Referring to fig. 1-5, the application provides an innovative design of a space-earth lock. The design includes a lock cylinder 1, a gear shaft 2, a rack 3, a latch bolt assembly 4, and a housing 5. The lock cylinder 1 includes a driving portion 11 and a first connecting portion 12, and the gear shaft 2 includes a gear portion 21 and a second connecting portion 22. The lock cylinder 1 and the gear shaft 2 are mutually connected through the first connecting part 12 and the second connecting part 22, so that stress transmission is realized. The gear shaft 2 and the rack 3 are respectively mounted on the housing 5, a shaft hole 51 is provided on the housing 5, and the gear shaft 2 is mounted in the shaft hole 51.
The rack 3 includes a rack portion 31, and the housing 5 is provided with a mounting groove 52 accommodating the rack portion 31 in the vertical direction. The mounting groove 52 has an opening at one end, and the rack portion 31 is mounted in the mounting groove 52 and engaged with the gear portion 21 of the gear shaft 2. This design allows the rack 3 to move freely in the vertical direction while maintaining engagement with the gear shaft 2. The open design of the mounting slot 52 is a key innovation, allowing the exposed end of the rack 3 to move away from the housing 5 during linear movement, thereby increasing the travel of the rack 3.
The rack 3 is detachably connected with the lock tongue assembly 4, so that the adaptability of the space lock is improved, and adjustment is allowed according to different door plate thicknesses or the requirements of the lock tongue 42. When the driving part 11 of the key cylinder 1 is rotated by an external force, it drives the gear part 21 to rotate, and the gear part 21 converts the rotational motion into up-and-down movement of the rack 3 in the vertical direction by engagement with the rack part 31.
The space-earth lock successfully solves the problems that the space-earth lock in the prior art is large in size and difficult to install on a thin door plate through ingenious structural design. Compared with the traditional heaven and earth lock, the design of the application controls the whole thickness within 8mm, and is thinner by nearly half than the common heaven and earth lock with the thickness of 15-20 mm. The compact design not only enables the top-bottom lock to be completely hidden in the thin door plate, but also greatly improves the convenience and the aesthetic property of installation.
In addition, compared with the traditional direct connecting rod transmission mechanism, the gear rack transmission mechanism realizes larger travel of the lock tongue 42 in the same space, and improves the reliability of locking and the smoothness of operation. The detachable lock tongue 42 is designed to solve the problem of poor adaptability of the traditional world lock, allows a user to replace different lock tongues 42 according to actual demands, and improves the universality and practicality of products.
In general, the design of the heaven and earth lock successfully solves a plurality of technical problems of thin door plate installation, locking reliability, adaptability and the like through innovative structures and ingenious mechanism arrangement, and provides a new technical scheme for the field of furniture safety locks.
Referring to fig. 7 and 8, in the above embodiments, the present application is implemented by implementing the method, which has the problem of how to connect the rack 3 and the link 6 and ensure the strength and stability of the link 6 when the housing 5 is thin.
In this regard, the application further provides a connecting rod 6, the rack 3 further comprises a third connecting part 32, the third connecting part 32 is externally arranged on the shell 5, one end of the connecting rod 6 is detachably mounted on the third connecting part 32 of the rack 3, the other end of the connecting rod 6 is detachably provided with a lock tongue assembly 4, one end, close to the rack part 31, of the mounting groove 52 is of a closed structure, and the closed structure is used for limiting the rack 3 which is driven to move up and down.
The connecting rod 6 is used as a transmission part between the rack 3 and the lock tongue assembly 4, and the detachable installation mode is convenient for maintenance and replacement. The design of the third connecting part 32 outside the housing 5 solves the problem of the size limitation of the housing 5, and provides enough space for the connection of the rack 3 and the connecting rod 6. The mounting groove 52 with one end of the closed structure limits the movement of the rack 3, prevents the rack 3 from being separated from the mounting groove 52 due to interference rotation of a user in the unlocking process, and ensures the reliability of the world lock. These technical features cooperate with each other to solve the problem of realizing the connection of the rack 3 and the connecting rod 6 in the thin-walled housing 5. The external third connection 32 allows the use of a thicker link 6, ensuring the strength of the link 6. Meanwhile, the design of the third connecting part 32 enables the upper connecting rod 6 and the lower connecting rod 6 to be positioned on the coaxial line, so that the overall stability and reliability of the lock are improved. The mounting groove 52 of the closed structure prevents interference operation of a user in the unlocking process, and reliability of the lock is improved.
In the present application, the connecting rod 6 may be made of various materials and structural designs. For example, it may be made of a metal material such as aluminum alloy or stainless steel to secure sufficient strength. The cross section of the connecting rod 6 can be circular, square or other polygonal, and the most suitable shape is selected according to specific requirements. The length of the connecting rod 6 can be adjusted according to the thickness of the door body 9, and is generally in the range of 50-200 mm.
Many variations of the design of the third connection 32 are possible. The device can be an integrally formed part of the rack 3, or can be fixedly connected with the rack 3 after being manufactured independently. The third connecting portion 32 may be cylindrical, square or other geometric shape in shape to facilitate a secure connection with the connecting rod 6. The thickness of the third connecting portion 32 is generally in the range of 9-12mm, so that sufficient strength can be ensured without excessively increasing the overall size.
The closed configuration of the mounting slot 52 may take a variety of forms. For example, the baffle may be formed integrally with the housing 5, or may be a stopper that is separately manufactured and then fixed to the housing 5. The height of the closure structure is typically designed to be about 1-2mm from the rack 3 so that the normal movement of the rack 3 is not affected while the movement of the rack 3 is restricted.
There is a close association and interaction between these features. The external design of the third connecting portion 32 is matched with the detachable mounting mode of the connecting rod 6, so that the problem of insufficient space in the thin shell 5 is solved, and greater flexibility is provided, so that maintenance and replacement are facilitated. At the same time, this design allows the use of thicker, stronger links 6, thereby improving the strength and stability of the overall lock. The closed structure of the mounting groove 52 interacts with the movement of the rack 3, preventing possible malfunction caused by excessive movement while ensuring the normal movement of the rack 3.
In practical application, the technical scheme of the application can be realized by taking a space-earth lock with the thickness of 8mm as an example, the third connecting part 32 of the rack 3 can be designed into a cylinder shape, the diameter is 10mm, and the height is 5mm. The connecting rod 6 is made of an aluminum alloy material, has a hollow structure with an outer diameter of 8mm and an inner diameter of 6mm, and has a length of 100mm. The connecting rod 6 is connected with the third connecting part 32 through threads, so that the disassembly and adjustment are convenient. The closed structure of the mounting groove 52 adopts an integrally formed baffle plate, and the distance between the baffle plate and the rack 3 is 1.5mm.
In the use process, when a user rotates the lock cylinder 1, the gear shaft 2 drives the rack 3 to move up and down. The rack 3 drives the connecting rod 6 to move through the external third connecting part 32, and the connecting rod 6 drives the lock tongue assembly 4 to realize locking or unlocking. Since the third connecting portion 32 is located outside the housing 5, even in the case of a thin housing 5, a sufficient connecting space and strength of the connecting rod 6 can be ensured. Meanwhile, the closed structure of the mounting groove 52 ensures that the rack 3 cannot be separated from the mounting groove 52 in the moving process, and the reliability of the lockset is improved.
Compared with the prior art, the technical scheme provided by the application has obvious advantages. Conventional world locks often have difficulty in mounting on the door panels due to the size constraints of the housing 5, or have to use thinner, lower strength links 6, affecting the overall performance of the lock. Through ingenious structural design, the application realizes reliable connection of the rack 3 and the connecting rod 6 while keeping the thinning of the shell 5, and ensures the strength of the connecting rod 6 and the stability of the whole structure. The design not only solves the problem of space limitation, but also improves the overall performance and reliability and durability of the space lock, so that the space lock can better adapt to the double requirements of modern furniture on safety and aesthetic property.
Referring to fig. 2, 7 and 8, in some embodiments, the present application is implemented by improving stability and reliability of the lock and preventing the rack 3 from being separated from the gear shaft 2 during movement.
In this regard, the present application further proposes a technical solution in which two racks 3 are provided, and the two racks 3 are oppositely and symmetrically provided at both sides of the gear shaft 2, and the gear portion 21 of the gear shaft 2 is simultaneously engaged with the rack portions 31 of the two racks 3.
According to the technical scheme, by arranging the two reversely symmetrical racks 3 and enabling the gear part 21 of the gear shaft 2 to be meshed with the two racks 3 at the same time, the technical effects that firstly, the two reversely symmetrical racks 3 improve the structural stability of the space-earth lock are achieved. When the gear shaft 2 rotates, the two racks 3 move in opposite directions at the same time, and the symmetrical movement can balance acting force, so that deflection or deformation possibly caused by single-side stress is reduced. Secondly, the double racks 3 increase the contact area with the gear part, and improve the transmission reliability. The gear part is meshed with the two racks 3 at the same time, so that the force transmission is more uniform, and the possible abrasion or fault risk of the single rack 3 is reduced. Furthermore, the design can realize more accurate locking and unlocking operations, the synchronous movement of the two racks 3 ensures the operation precision, and the locking and unlocking accuracy of the world lock is improved. Finally, the double rack structure enhances the overall bearing capacity of the lock. When external force is applied, the two racks 3 can share pressure together, so that the anti-damage capability of the lockset is improved.
In the embodiment of the present application, the two racks 3 may be of the same structural design, but are installed on both sides of the gear portion 21 in an inversely symmetrical manner. The symmetrical arrangement not only ensures the balance of the structure, but also simplifies the production and assembly processes. The rack 3 can be made of metal materials with good wear resistance, such as stainless steel or hard alloy, so as to improve the service life and the reliability.
The gear portion 21 of the gear shaft 2 may be of a double-sided gear design, i.e. one gear is provided on each side of the shaft, respectively engaged with the racks 3 on the corresponding sides. The design can further increase the engagement area and improve the transmission efficiency and stability. The tooth form of the gear can be an involute tooth form, and the tooth form can keep a constant transmission ratio in the transmission process, so that vibration and noise are reduced.
The depth of engagement of the rack 3 with the gear is an important parameter and it is generally recommended that the depth of engagement be between 1/3 and 1/2 of the tooth height. Too shallow engagement may result in unstable transmission, while too deep engagement may increase friction and drag. In the present application, the depth of engagement can be set to about 2/5 of the tooth height to achieve the optimum balance.
The double rack design of the present application forms a coordinated whole with the previous single rack structure. The gear shaft 2 serves as an intermediate link for connecting the lock cylinder 1 and the racks 3, and by driving the two racks 3 simultaneously, not only is the transmission efficiency improved, but also more accurate position control is realized. The design ensures that the whole locking and unlocking process is smoother and more reliable, and solves the possible problems of instability and inaccuracy of a single rack structure.
During the locking process, when the user turns the lock cylinder 1, the gear shaft 2 starts to rotate. Since the gear portion 21 is simultaneously engaged with the two reversely symmetrical racks 3, the rotational movement of the gear is converted into the reversely linear movement of the two racks 3. This reverse motion not only balances the forces, but also increases the speed of locking and unlocking. For example, if a single rack 3 is moved 10mm in one operation, the same locking effect can be achieved by moving two racks 3 each 5mm in a double rack 3 system, which means that the user requires less operating force and less operating time to complete locking or unlocking.
In addition, the double rack design also enhances the anti-damage capability of the world lock. When an external force tries to forcibly open the lock, the acting force is dispersed to the two racks 3, and the stress born by each rack 3 is reduced, so that the anti-damage capability of the whole lock is improved. Meanwhile, since the two racks 3 are arranged in opposite symmetry, any attempt to unlock by prying or vibrating becomes more difficult because the forces on both sides cancel each other out.
The length of the tooth-free section of the rack portion 31 near the closed end of the mounting groove 52 is typically between 5mm and 20mm, and the tooth-free section may be smoothly polished to reduce friction with other components, and the edges may be slightly chamfered to avoid sharp edges.
In general, the symmetrical structure arrangement of the double racks effectively solves the defects of the traditional world lock in the aspects of stability, reliability and operation efficiency, and meanwhile, the traditional design often neglects the processing of the movement limit position of the racks, so that the racks are easy to separate. The application skillfully avoids the problem by arranging the toothless section at the end part of the rack 3. The innovation points not only improve the performance and reliability of the world lock, but also enhance the durability and safety of the product, and provide a new thought and solution for the design of the furniture safety lock.
In the implementation process of the application, the problem of further preventing the rack 3 from being separated from the gear shaft 2 in the movement process is also existed.
Referring to fig. 2 and 3, in order to solve this problem, in the embodiment of the present application, a boss 313 may be disposed on the end of the rack portion 31 near the closed end of the mounting groove 52 toward the gear portion 21, and the height of the boss 313 may be designed according to practical requirements. It may be generally set to between 1/4 and 1/2 of the thickness of the rack 3 to ensure that the rack portion 31 is effectively prevented from being disengaged from the gear portion 21 when the rack 3 is moved to the limit position, without excessively disturbing the normal gear engagement. The boss 313 may be shaped in a circular arc or a slope to reduce the impact force with the gear part 21.
The application realizes more direct and effective anti-disengagement protection by arranging the boss 313 on the rack 3. The safety and the reliability of the world lock are improved through the innovative design.
Referring to fig. 7, in the above embodiments, in the implementation process of the present application, there is a problem that when the door body 9 is embedded and the upper and lower ends have the lock seats 81, how to realize stable connection between the latch bolt assembly 4 and the connecting rod 6 and ensure the locking effect.
In this regard, the application further proposes a technical scheme that the latch bolt assembly 4 comprises a latch bolt connector 41 and a latch bolt 42, wherein one end of the latch bolt connector 41 is fastened on the connecting rod 6, and the other end is fastened on the latch bolt 42, and the latch bolt 42, the latch bolt connector 41 and the connecting rod 6 are positioned on the coaxial line.
The lock tongue assembly 4 consists of a lock tongue joint 41 and a lock tongue 42, and the lock tongue 42 is connected with the connecting rod 6 through the lock tongue joint 41. One end of the lock tongue joint 41 is fixedly connected with the connecting rod 6, and the other end is fixedly connected with the lock tongue 42 to form an integral structure. The bolt 42, the bolt joint 41 and the connecting rod 6 are designed on the same axis, so that the force transmission can be ensured to be more direct and efficient. This coaxial design helps to reduce stress concentrations and improves the stability and reliability of the overall locking mechanism. When the lock cylinder 1 drives the gear shaft 2 to rotate, the rotation motion can be converted into the linear motion of the lock tongue 42 through the transmission of the rack 3 and the connecting rod 6, so that the locking or unlocking function is realized. The lock tongue 42, the lock tongue connector 41 and the connecting rod 6 are designed on the same axis, and the condition is suitable for realizing locking when the door body 9 is embedded, and the lock tongue 42 directly correspondingly stretches into the lock seat 81 of the cabinet body 8. This design not only simplifies the construction, but also increases the strength and durability of the locking mechanism. Meanwhile, as all the parts are positioned on the same axis, the installation and adjustment become easier, and the assembly efficiency and the maintenance convenience of the product are improved.
In embodiments of the present application, the tongue tab 41 may take a variety of forms to effect connection with the link 6 and tongue 42. For example, the tongue joint 41 may be fastened to the link 6 and the tongue 42 by screwing, snap-fitting, or socket-fitting. The connection modes can be selected according to specific application scenes and requirements so as to ensure the firmness and reliability of connection.
The tongue tab 41 is designed to take into account different materials and configurations. For example, the tongue tab 41 may be made of a metallic material (e.g., stainless steel or aluminum alloy) to provide sufficient strength and durability. Meanwhile, the shape of the latch tongue joint 41 may be designed in a cylindrical shape or a shape with protrusions to increase the contact area with the connecting rod 6 and the latch tongue 42, further improving the stability of connection.
The design of the locking bolt 42 may also be optimized for different application requirements. For example, it may be designed in a shape with an inclined surface so that the latch bolt 42 is smoother when entering the lock housing 81.
In the application, the design that the lock tongue 42 and the lock tongue joint 41 are coaxial with the connecting rod 6 is combined with the design of the rack 3 and the gear shaft 2, so that an efficient transmission system is formed. When the key cylinder 1 drives the gear shaft 2 to rotate, the engagement of the gear portion 21 with the rack portion 31 causes the rack 3 to move linearly. The motion is directly transmitted to the lock tongue joint 41 and the lock tongue 42 through the connecting rod 6, and the force transmission is more direct because the three parts are positioned on the same axis, so that the energy loss is reduced, and the response speed of locking and unlocking is improved.
In addition, the coaxial design also simplifies the structure of the whole locking mechanism, and reduces the production cost and the maintenance difficulty.
Referring to fig. 8, in some embodiments of the present application, in the implementation process, there is a problem how to extend the lock tongue 42 into the lock seat 81 of the cabinet 8 to lock under the condition that the door 9 is externally connected and the upper and lower ends have no lock seats 81, so as to realize the locking effect of the top-bottom locking in the cabinet 8.
In this regard, the application further provides a technical scheme that the lock tongue assembly 4 comprises a lock tongue connector 41 and a lock tongue 42, wherein the left end and the right end of the lock tongue connector 41 are respectively provided with a mounting hole, the connecting rod 6 is perpendicular to the lock tongue connector 41 and is fastened on one of the mounting holes, the lock tongue 42 is perpendicular to the lock tongue connector 41 and is fastened on the other mounting hole, and the lock tongue 42 and the connecting rod 6 are positioned on the opposite sides of the lock tongue connector 41.
According to the technical scheme, the problem that the lock tongue stretches into the cabinet body 8 to be locked with the lock seat 81 is solved by designing the lock tongue assembly 4 with a special structure, and under the condition that the door body 9 is externally connected and the lock seats 81 are not arranged at the upper end and the lower end of the door body, the lock tongue 42 is connected through the epitaxial lock tongue connector 41. The tongue joint 41 serves as a connecting member, and is provided with mounting holes at both ends thereof for connecting the link 6 and the tongue 42, respectively. The design makes the latch bolt joint 41 extend to the door body 9, and the latch bolt 42 connected to the extension part of the latch bolt joint 41 realizes translation, and extends to the radial locking position of the latch bolt 42, so that more locking scenes can be matched. Install spring bolt 42 and connecting rod 6 in the different sides that spring bolt connects 41, can be when the application less adapting unit lets spring bolt 42 translation, ensure that connecting rod 6 and spring bolt 42 are located the upper and lower different end position that spring bolt connects 41 respectively, ensure that spring bolt 42 stretches into the lock seat 81 of the upper and lower end of cabinet body 8 and accomplish the locking, guaranteed the realization of locking function.
The design that the lock tongue 42 and the connecting rod 6 are located on the opposite side of the lock tongue joint 41 not only solves the problem of space layout, but also improves the locking stability. When the lock tongue 42 extends out of the lock, the thrust of the connecting rod 6 and the shearing resistance of the lock tongue 42 form a moment, and the stability of the whole lock structure is increased.
According to the technical scheme, when the problem of locking the external door body 9 is solved, the extension of the position of the lock tongue 42 is realized through the design of the lock tongue connector 41. When the lock cylinder 1 drives the gear shaft 2 to rotate, the gear shaft 2 drives the rack 3 to move up and down, and the rack 3 drives the lock tongue joint 41 to move through the connecting rod 6. Since the lock tongue 42 is mounted at the other end of the lock tongue joint 41, the lock tongue 42 can extend out of the edge of the door body 9 and directly cooperate with the lock seat 81 on the cabinet body 8. The structure design overcomes the limitation that the upper end and the lower end of the external door body 9 are not provided with the lock seats 81, and realizes the application of the world lock on the external door body 9.
Compared with the prior art, the scheme of the application has the advantages that firstly, the problem that the external door body 9 cannot use a traditional world lock is solved, the application range of the world lock is expanded, secondly, the position of the lock tongue 42 is adjustable due to the design of the lock tongue connector 41, the lock tongue is suitable for door bodies 9 and cabinet bodies 8 with different thicknesses, thirdly, the problem of space layout is solved due to the design of the installation of the lock tongue 42 and the connecting rod 6 at different sides, the stability of a locking structure is improved, and finally, the whole structure is compact in design and the attractiveness of the cabinet body 8 is not influenced.
The specific embodiment is as follows, taking a standard wardrobe as an example, the thickness of the door body 9 is 18mm, and the external connection type installation is adopted. The bolt joint 41 is made of 304 stainless steel material, and has the length of 40mm, the width of 20mm and the thickness of 8mm. The mounting holes at the two ends of the lock tongue joint 41 have diameters of 6mm, one end of the mounting holes is in threaded connection with the connecting rod 6 with the diameter of 6mm, and the other end of the mounting holes is in snap-fit connection with the lock tongue 42. The length of the bolt 42 is 25mm, the width is 15mm, and the thickness is 5mm. When the lock cylinder 1 rotates to drive the gear shaft 2 to rotate, the rack 3 moves up and down to drive the connecting rod 6 to move for 15mm, and at the moment, the lock tongue 42 can extend out of the edge 10mm of the door body 9 through the transmission of the lock tongue connector 41 and just enters the lock seat 81 on the cabinet body 8 to realize locking. In addition, the latch tab 41 may be provided with a covering area that, when installed, covers the opening in the door 9 that is provided for the latch tab 41, regardless of whether the lock is open or closed.
Compared with the prior art, the technical scheme provided by the application has obvious advantages. The conventional world lock is generally only applicable to the embedded door body 9, but cannot be used on the external door body 9. The present application successfully addresses this problem by a smart design of the latch bolt assembly 4. The introduction of the tongue joint 41 not only enables the tongue 42 to extend beyond the edge of the door body 9, but also provides a flexible way of installation, accommodating door bodies 9 of different thickness. The design of the bolt 42 and the connecting rod 6 installed on different sides solves the space layout and improves the safety performance. In addition, the application has compact structural design, does not influence the overall beauty of the cabinet body 8, and meets the dual requirements of modern furniture on functionality and beauty. The innovation points enable the lock to solve the locking problem of the external door body 9, improve the applicability and reliability of the lock and provide a new thought and scheme for the design of furniture locks.
Referring to fig. 2, in some embodiments of the present application, there is a problem in implementing the present application in how to provide position feedback during unlocking and locking of the lock cylinder 1, and prevent damage to components caused by over-rotation of the lock cylinder 1.
In this regard, the present application further proposes a positioning feedback unit 7, wherein the positioning feedback unit 7 comprises a spring 71 and a ball 72, one end of the spring 71 elastically abuts against and acts on the ball 72 in the housing 5, the other end of the spring 71 abuts against and acts on the ball 72, the ball 72 is elastically abutted against the rack portion 31 of the rack 3, a first groove 311 and a second groove 312 are sequentially provided at a position of the rack portion 31 of the rack 3 near the third connecting portion 32, when the rack 3 moves up and down, the ball 72 is acted on by elastic force generated by compression deformation of the spring 71, when the ball 72 abuts against the groove of the rack portion 31, feedback is generated by the driving portion 11 of the lock cylinder 1, when the ball 72 abuts against the groove of the rack portion 31, the ball 72 is in a state of moving to the unlock position or the lock position by cooperation between the ball 72 and the two grooves, thereby judging that the lock of the lock cylinder 1 is in place, and preventing damage to the rack 3 or the lock cylinder 1 caused by continued rotation of the driving portion 11 of the lock cylinder 1, when the rack 3 moves to the unlock position, the ball 72 of the positioning feedback unit 7 elastically abuts against the first groove 311, and when the rack 3 moves to the lock cylinder 1. The positioning feedback assembly 7 may also be a leaf spring fixed in the housing 5, the leaf spring being centrally arched, the arched portion being in elastic abutment against the rack portion 31.
The positioning feedback assembly 7 of the present application is comprised of a spring 71 and a marble 72, providing a simple and effective feedback mechanism. The elastic force generated by the compression of the spring 71 is transmitted to the rack 3 through the marble 72, and when the marble 72 contacts with the groove, a significant resistance change is generated, thereby realizing position feedback. Two grooves (a first groove 311 and a second groove 312) are provided at positions of the rack portion 31 near the third connecting portion 32, corresponding to the unlock and lock positions, respectively. This design enables significant feedback to be generated at a particular location. As the rack 3 moves, the marble 72 slides on the surface of the rack 3. When the marble 72 enters the recess, a significant resistance change is generated, causing the rotational resistance of the driving portion 11 of the key cylinder 1 to suddenly increase, which can be perceived by the operator. By this feedback mechanism, the operator can judge whether the world lock has reached the unlock or lock position, thereby avoiding the continued rotation of the drive portion 11 of the key cylinder 1, and preventing damage to the rack 3 or the key cylinder 1.
The present application also proposes to use a reed fixed in the housing 5 as an alternative to the positioning feedback assembly 7, the arched portion of the reed being in contact with the rack portion 31, as well as to achieve the position feedback function.
There are many variations of the groove design on the rack 3. In addition to simple semicircular grooves, V-shaped, square or trapezoidal designs, etc. can be used to provide different tactile sensations and feedback strengths. The depth and width of the grooves can be adjusted as required, and are typically between 0.5mm and 2mm in depth and between 1mm and 3mm in width. The position of the groove can be finely adjusted according to actual requirements so as to ensure that feedback is provided at the optimal position.
The mating design of the positioning feedback assembly 7 with the rack 3 and the housing 5 is of vital importance. The pre-pressure of the spring 71 needs to be carefully adjusted to ensure that the marble 72 can provide sufficient feedback force without causing excessive resistance to movement of the rack 3. Typically, the pre-compression force of the spring 71 may be set between 0.5N and 2N. The contact area of the marble 72 with the surface of the rack 3 also needs to be considered, and an excessively large contact area may increase friction, while an excessively small contact area may cause inaccurate positioning.
The reed can alternatively be designed to take into account a number of factors. The reed can be made of elastic steel, phosphor copper or titanium alloy, and the thickness is usually between 0.1mm and 0.5 mm. The spring arch height and shape directly affect the strength and characteristics of the feedback, and the feedback effect can be optimized by adjusting these parameters.
The design of the present application provides significant advantages over locks of the prior art that lack a positive feedback mechanism. The traditional world lock often relies on the experience of an operator to judge whether to be in place or not, and misoperation easily occurs. The application realizes reliable position sensing through a simple and ingenious mechanical structure without complex electronic elements, ensures the realization of functions, maintains the control of the simplicity and the cost of the structure, effectively prolongs the service life of the lock and reduces the maintenance and replacement requirements.
Referring to fig. 7 and 8, in some embodiments, the present application is implemented by the connection method of the connecting rod 6 and the third connecting portion 32 of the rack 3, and the problem of laborious operation caused by the heavy weight of the connecting rod 6.
In this regard, the present application further proposes a technical solution in which the connecting rod 6 is of a hollow structure, the connecting rod 6 is made of aluminum, and one end of the connecting rod 6 can be fastened and connected with the third connecting portion 32 of the rack 3 through a jackscrew.
The hollow structure of the connecting rod 6 can effectively reduce the weight, and simultaneously maintain enough strength. This design solves the problem of laborious operations caused by the heavy weight of the connecting rod 6. The connecting rod 6 adopts aluminum material, so that the weight can be effectively reduced, the strength is ensured, and the problem of labor-consuming operation caused by large weight of the connecting rod 6 is solved. The hollow connecting rod 6 also provides an internal space, which is convenient to connect in a fastening manner. The connecting rod 6 is fixedly connected with the third connecting part 32 of the rack 3 through the jackscrew, so that the connecting mode saves space and is suitable for being placed in a limited installation space by a space lock. The jackscrew connection is used primarily for the shaft bore 51 to prevent relative movement by bearing against the shaft. This connection ensures the stability and reliability of the connection between the connecting rod 6 and the third connecting portion 32, while also facilitating later disassembly and maintenance.
The connecting rod 6 is made of aluminum alloy, and particularly can be 6061-T6 or 7075-T6 aviation grade aluminum alloy. These materials have the characteristics of high strength and low density, further reduce the weight of the connecting rod 6, and simultaneously ensure the strength and durability of the connecting rod 6.
The connection of the connecting rod 6 and the third connecting part 32 of the rack 3 adopts a jackscrew fixing mode. The jackscrew can be made of stainless steel or high-strength alloy steel according to the specification M3 or M4. The length of the jackscrew is determined by the thickness of the connection site, typically between 5mm and 10 mm. The jackscrews may be arranged in a position on the end face of the end of the connecting rod 6.
This design provides a good fit with the previously described rack 3 and housing 5 configuration. Because of the thin thickness of the housing 5 (only 7-9 mm), the connection of the connecting rod 6 to the rack 3 must be made outside the housing 5. The hollow connecting rod 6 is designed to not only reduce the weight, but also provide an internal space for the connection of the jackscrews, which saves space and ensures the stability of the connection.
According to the technical scheme, the weight of the connecting rod 6 is remarkably reduced by adopting the hollow structure and the connecting rod 6 made of aluminum. Compared with the traditional solid steel connecting rod 6, the hollow aluminum connecting rod 6 can reduce the weight by more than 50 percent. The resistance when the world lock is operated is greatly reduced, and the user experience is improved. Meanwhile, the strength of the connecting rod 6 is not affected by the hollow structure and the aluminum material, so that the reliability and the durability of the world lock are ensured.
The manner of the jackscrew connection solves the problem of achieving reliable connection of the connecting rod 6 with the third connecting portion 32 in a limited space. The connecting mode does not need an extra connecting piece, and the hollow structure of the connecting rod 6 is directly utilized to realize connection, so that the space is saved, and the connection firmness is ensured. Meanwhile, the jackscrew connection mode is convenient for disassembly and maintenance in the future, so that maintainability of the world lock is improved, various requirements of the world lock in actual use are fully considered, and design ingenious and practicality are embodied.
Referring to fig. 7 and 8, in some embodiments of the present application, during the implementation process, the problem that abnormal sound may be generated during the movement of the connecting rod 6, which affects the use experience and the product quality is also existed.
In this regard, the present application further proposes that the outer surface of the connecting rod 6 is covered with more than one soft member 61, and the soft member 61 is used for eliminating abnormal sound generated when the connecting rod 6 moves.
According to the technical scheme, the problem of abnormal sound generated when the connecting rod 6 moves is solved by coating the soft piece 61 on the outer surface of the connecting rod 6. The soft member 61 serves as a buffer material capable of absorbing vibration and impact generated when the link 6 moves, thereby reducing or eliminating abnormal sound. The soft part 61 mainly plays roles in vibration reduction, buffering, gap filling, sound insulation and the like, and can effectively eliminate abnormal sound generated when the connecting rod 6 moves, so that the use experience of the space lock and the product quality are improved.
The flexible member 61 of the present application can take a variety of materials and forms. For example, a material having elastic and cushioning properties such as rubber, silicone, soft plastic, or foam material may be used. The flexible member 61 may be a unitary sleeve structure or a segmented annular structure. In some embodiments, the soft member 61 may have a multi-layered structure, wherein an inner layer is made of a material having a high hardness to secure the strength of the connecting rod 6, and an outer layer is made of a soft material to enhance the shock absorbing effect.
The number and distribution of the flexible members 61 can be adjusted according to actual requirements. The soft member 61 may be uniformly coated on the entire outer surface of the connecting rod 6, or may be partially coated only at a critical position where collision or vibration is likely to occur. For example, the flexible member 61 may be provided in a point-by-point manner at the connection of the link 6 to the rack 3, at the connection of the link 6 to the tongue assembly 4, and at the intermediate portion of the link 6.
The thickness of the flexible member 61 may be determined according to the overall size of the world lock and the diameter of the connecting rod 6. Typically, the thickness of the flexible member 61 may be between 0.5mm and 3mm to ensure a sufficient cushioning effect without excessively increasing the overall diameter of the connecting rod 6.
In the solution of the present application, the connection and fixation of the flexible element 61 to the connecting rod 6 is also an important factor to be considered. The flexible member 61 may be fixed to the surface of the connecting rod 6 by means of bonding, hot pressing, a sleeve, or molding. By selecting a proper connection mode, the soft piece 61 can be ensured not to fall off or shift in the movement process of the connecting rod 6, so that the effects of vibration reduction and noise reduction are continuously exerted.
In addition, the soft member 61 fills the gap between the connecting rod 6 and the surrounding parts, reducing the relative movement between the parts, and thus reducing the frictional noise. The soundproofing effect of the soft member 61 also blocks the propagation of sound generated when the link 6 moves.
Through the design, the application not only remarkably improves the acoustic performance of the world lock, but also improves the use experience and quality of the product. It is worth noting that this improvement does not affect the main function of the connecting rod 6, since the design of the soft member 61 allows for the movement characteristics and space constraints of the connecting rod 6.
Referring to fig. 2 and 7-10, in some embodiments, the problem of how to install the top-bottom lock on the cabinet door to realize the locking function of the cabinet door is also existed in the implementation process of the application.
In this regard, the application further provides a cabinet door adopting a top-bottom lock, wherein the top-bottom lock is embedded in the door body 9.
According to the technical scheme, the world lock is embedded in the door body 9, so that integration of the world lock and the cabinet door is realized. The design has the advantages that firstly, the embedded installation can integrate the top and bottom lock and the cabinet door, and the overall aesthetic property is improved. The top and bottom lock will not protrude from the surface of the door body 9, avoiding possible collision or damage caused by exposed parts. Second, the embedded installation enhances the security of the world lock. Since the lock body is hidden inside the door body 9, it is difficult for a potential vandalism to access the key components of the lock, thereby improving the anti-theft performance. And the mounting mode can fully utilize the thickness of the cabinet door to provide mounting space for the space lock, so that the lock core 1, the gear shaft 2, the rack 3 and other parts can be well protected. Finally, the embedded installation can ensure that each component (such as the bolt assembly 4) of the top-bottom lock can be accurately aligned with the lock hole or the lock seat 81 of the door frame or the ground, thereby improving the reliability and stability of locking.
In the application, the top-bottom lock is embedded in the door body in a plurality of realization modes. One possible implementation way is to reserve a groove matching with the shape of the space lock inside the cabinet door, and the space lock can be completely embedded in the groove. Another way is to design the cabinet door as a hollow structure, such as an aluminum frame cabinet door, and the space lock can be installed in the inner space of the cabinet door. The modular design can be adopted, the space lock is divided into a plurality of modules, and the modules are respectively embedded into different positions of the cabinet door, so that more flexible installation is realized.
The integration of the world lock and the cabinet door is not just a simple physical combination, but forms a complete whole. For example, the latch bolt assembly 4 of the space-time lock can be precisely aligned with the rim or bottom of the cabinet door, ensuring accuracy and stability of the lock. Not only ensures the beautiful appearance, but also is convenient to use.
In the concrete implementation, the proper model of the world lock can be selected according to the thickness and the material of the cabinet door. For example, for a metal cabinet door, it may be necessary to add ribs or support structures inside the door body 9 to carry the weight of the heaven and earth lock and provide sufficient rigidity.
The technical scheme provided by the application can effectively solve the problem that the world lock is arranged on the cabinet door, and meanwhile, the reliable locking of the cabinet door is realized. Through with world lock inlay formula setting in the door body 9, core parts such as lock core 1, gear shaft 2, rack 3 are all hidden inside the cabinet door, have improved the security greatly. The bolt assembly 4 can be accurately extended out through a pre-designed opening, and is perfectly abutted with a lock hole of a door frame or the ground, so that the locking reliability is ensured. In addition, the design mode fully utilizes the internal space of the cabinet door, the appearance and the use of the cabinet door are not affected, and meanwhile, the collision or the artificial damage possibly suffered by the exposed parts is avoided.
In addition, the embedded design can also protect the mechanical parts of the world lock better, prolong the service life of the world lock, and reduce the maintenance requirement. The novel integration mode represents a new direction of cabinet door lock design, not only meets the functional requirement, but also gives attention to the attractiveness and the safety.
