Today, people increasingly pursue life, indoor environmental pollution always puzzles us, especially furniture pollution as main articles, and people pay more attention. The traditional furniture cabinet body is a wood product made of density boards, shaving boards or solid wood, and the problem that formaldehyde exceeds standard is commonly existed in the wood product, which definitely causes great harm to people living indoors for a long time and seriously affects the health of people. For this reason, the structure of stainless steel wallboard has appeared among the prior art, through utilizing the corrosion resistant plate as the dado, not only makes wallboard environmental protection healthy more, and the life of corrosion resistant plate is longer moreover.
In walls, a door opening is usually left, and a door is installed in the door opening. In the prior art, door handles are arranged on the doors, so that the doors and the wallboards are not coordinated. In some home furnishings, the door lock mechanism is eliminated in order to allow coordination between the door and the wall panel. However, after the door lock mechanism is not provided, the door leaf can be closed inaccurately, and the door lock is not provided, so that inconvenience is brought to use.
For this reason, the present invention proposes a stainless steel door that can form a better call with a panel, and specifically, referring to fig. 1 to 5, the stainless steel door includes a door frame 100 and a door leaf 200, wherein the door frame 100 is used for being fixedly installed on a door opening, and the door leaf 200 is hinged with the door frame 100 through a hinge 300.
For example, in the present embodiment, the hinge 300 is installed at the left side, and the door leaf 200 of the present embodiment is opened inward (or backward). In the closed state, the door leaf 200 is flush with the surface of the door frame 100.
When the door frame 100 is installed, the installation edge 111 and the wall body are fixedly installed through expansion bolts or self-tapping screws, a second clamping groove 114 is formed in the outer side of the installation edge 111, similarly, the wall body is fixedly installed on the second clamping groove 114, after the section bar main body 110 is fixed on the wall body, the installation bolts are embedded into the second clamping groove 114 to cover the installation bolts, the wall body is covered by the aid of the wall body through embedding the wall body into the two sides of the section bar main body 110, and accordingly plastering operation on the wall body can be omitted, and decoration efficiency is improved.
In addition, in order to ensure better tightness of the door leaf 200 and the door frame 100, a step surface 115 is provided on the front side of the profile main body 110, and when the door is closed, the edge of the door leaf 200 abuts against the step surface 115, thereby achieving a tight door closing effect. Furthermore, by providing the sealing strip on the step surface 115, better sealing and silencing effects can be achieved.
The door leaf 200 includes a frame 230, and the frame 230 may be formed by welding a plurality of frame profiles, or assembling a plurality of frame profiles by hardware such as a corner bracket. In addition, in order to play a better supporting role, the frame 230 may further be provided with a filling profile, and by assembling the filling profile with the frame profile, the installation efficiency and the installation flexibility may be improved. And two stainless steel panels, namely, a first panel 210 and a second panel 220, are covered on the outer side of the frame 230. The first panel 210 is located at the outer side of the frame 230, and the second panel 220 is installed at the inner side of the frame 230. The first panel 210 and the second panel 220 can wrap up and down, left and right, front and back six end surfaces of the frame 230, so that the first panel 210 and the second panel 220 are formed by bending.
Specifically, the first panel 210 includes a first surface 211, a first bent edge 212 is disposed around the first surface 211, a first clamping edge 213 is disposed at an end of the first bent edge 212 and connected to the first surface 211, the second panel 220 includes a second surface 221, a second bent edge 222 is disposed around the second surface 221, a first end of the second bent edge 222 is connected to the second surface 221, and a second clamping edge 223 is disposed at an end of the second bent edge 222, and the second clamping edge 223 and the first clamping edge 221 are closely abutted to each other.
In addition, in order to match the stepped surface 115, the length of the second panel 220 is greater than the length of the first panel 210, so that a second stepped surface is formed between the first bent edge 212 and the second bent edge 222, and the second stepped surface can match the stepped surface 115. Thus, two mutually matched step surfaces can be utilized between the door frame 100 and the door leaf 200, so that no visible light gap is reserved in the door closing state, and the sealing effect is better.
In order to enable the door leaf 200 to be reliably closed in the door frame 100, a concealed door lock mechanism 400 is provided on the right side of the door leaf 200. Specifically, the door lock mechanism 400 includes a pressing block 410, and the pressing block 410 is mounted on the outer side (i.e., the first panel 210) of the door leaf 200. The pressing block 410 may be set to be similar to the palm of a human hand, the pressing block 410 is movably connected with the door leaf 200, and the pressing block 410 can move along the front-back direction relative to the door leaf 200. Whereas the outer surface of the pressing block 410 is normally substantially flush with the first surface 211 of the first panel 210, i.e. the pressing block 410 is not protruding from the outer surface of the door leaf 200. In order to ensure rigidity, the pressing block 410 has a certain thickness, and the thickness of the pressing block 410 is also greater than the thickness of the plate of the first panel 210, so that the pressing block 410 can be relatively integrally embedded into the door leaf 200. Therefore, in order to ensure a reliable movement of the pressing block 410, the pressing block 410 is slidably connected with the frame 230 of the door leaf 200. And the first surface 211 is provided with a through hole, and the size and shape of the through hole are matched with those of the pressing block 410. It can be appreciated that, on the premise of ensuring that the pressing block 410 can move smoothly, the smaller the gap between the pressing block 410 and the through hole is, the better the consistency of the outer surface of the door leaf 200 can be ensured.
In addition, the door lock mechanism 400 further includes a lock pin 420 and a transmission mechanism 430, where the lock pin 420 is disposed on an upper end surface of the right side of the door leaf 200 in a vertically sliding manner, and correspondingly, a lock seat 120 matched with the lock pin 420 is disposed on an upper portion of the door frame 100, and the lock seat 120 is nested and installed in the profile main body 110. The transmission mechanism 430 is used for realizing the transmission of the motion between the pressing block 410 and the locking pin 420. It will be appreciated that there are many ways of the described transmission 430. As described above, the pressing block 410 moves along the front-back direction relative to the door leaf 200, and the locking pin 420 moves up and down relative to the door leaf 200, and the transmission mechanism only needs to drive the locking pin 420 to move down when the pressing block 410 moves backward. It will be appreciated that the door leaf 200, unlike conventional solid wood doors, includes a frame 230, which frame 230 has a large cavity, because it is a stainless steel door, thus providing great convenience in the installation of the transmission mechanism 430.
As can be seen from this, in this embodiment, the lock and unlock of the door 200 and the door frame 100 are achieved by controlling the lock pin 420 located above the door 200 by the pressing block 410 which can be hidden in the door 200. Compared with the traditional arrangement of the lock tongue on the side surface of the door leaf 200, the matched lock seat is arranged on the side surface of the door frame 100, and the lock pin and the lock seat are arranged at the tops of the door leaf and the door frame, so that the side surface of the door leaf is tidier and more attractive, and the appearance consistency of products is better. Since the door leaf 200 is generally more than 2.3 meters, the locking pin 410 and the lock base 120 are not visible to the user in normal use. Meanwhile, since the pressing block 410 is hidden on the outer surface of the door leaf 200, the gap between the pressing block 410 and the door leaf 200 can be very small, so that the structure of the pressing block 410 can not be seen at first glance, and therefore, the consistency between the door leaf 200 and the door lock mechanism 400 is better, and the product is more attractive. In the present embodiment, since the door 200 is opened inward (rearward) and the unlocking operation of the pressing block 410 is also moved rearward, the unlocking operation of the door lock mechanism 410 and the door opening operation can be performed at one time, and the feeling of use can be improved. In the conventional door lock, when the door is to be unlocked, the handle is often required to be twisted by hand, and then the door is pushed backwards by force under the condition of keeping the twist. Therefore, the door opening operation includes two steps, but after the door lock structure of the embodiment is adopted, only one step is needed, namely, the pressing block 410 is forcefully pushed backwards, so that the door lock can be released and the door leaf can be opened, and the operation is simpler and more convenient.
In the above-described embodiments, it is described how the present solution enables the door to be opened from outside, and it will be further described how the door is opened from inside.
As described above, in the present embodiment, the door 200 is opened inward, and the door 200 is opened inward only because the door 200 is engaged with the door frame 100 via the step surface. I.e. if it is desired to open the door from the inside, it is necessary to pull the door inwards. Therefore, a handle 440 is provided on the second panel 220 of the door leaf 200, and the handle 440 can be connected to the transmission mechanism 430 and is connected to the lock pin 420 in a transmission manner. When the handle 440 is pulled backward with force, the unlocking of the door and the opening of the door leaf can be realized, and the same actions are performed at a time, thereby improving the convenience of operation.
Specifically, the transmission mechanism 430 may be provided with a main shaft 431, the main shaft 431 penetrates through the door leaf 200 along the front-back direction and is sleeved with the frame 230, that is, the main shaft 431 can move back and forth relative to the frame 230, the pressing block 410 is mounted at the front end of the main shaft 431, the handle 440 is mounted at the rear end of the main shaft 431, and linkage of the pressing block 410 and the handle 440 can be realized by using the main shaft 431, that is, when the pressing block 410 moves backward under force, the handle 440 is synchronously driven to move backward by the main shaft 431, and similarly, when the handle 440 is pulled backward by force, the pressing block 410 also moves backward synchronously. As described above, when the pressing block 410 moves backward, the locking pin 420 is driven to move downward, so as to unlock the door leaf 200 and the door frame 100.
In order to facilitate the installation of the spindle 431 and the frame 230, the transmission mechanism 430 further includes a base 432, the base 432 is provided with a guiding structure such as a guiding hole or a guiding slot, the spindle 431 is slidably connected with the base 432 back and forth through the guiding structure, and the base 432 is fixedly installed in the frame 230. Furthermore, in order to improve the smoothness of the forward and backward movement of the spindle 431, the base 432 may be made of a wear-resistant material, and grease may be disposed in the guide hole, so as to improve the smoothness of the spindle 431 during the forward and backward movement.
As described above, the main function of the transmission mechanism 430 is to convert the forward and backward movement of the pressing block 410 (or the spindle 431) into the up and down movement of the locking pin 420, and in order to achieve the above function, the transmission mechanism 430 may adopt the following scheme:
Referring to fig. 5, further as a preferred embodiment, the transmission mechanism 430 further includes a connecting rod 433, an upper end of the connecting rod 433 is connected to the locking pin 420, a first wedge block 434 is disposed at a lower end of the connecting rod 433, a second wedge block 435 is disposed on the main shaft 431, and the first wedge block 434 and the second wedge block 435 are abutted with each other.
The connecting rod 433 extends along the up-down direction, and the connecting rod 433 has good rigidity and can play a role in force transmission. As mentioned above, since the locking pin 420 is installed at the top of the door leaf 200 and the pressing block 410 is generally installed in the middle of the door leaf 200, the transmission between the two components is realized by a connecting rod 433, therefore, the length of the connecting rod 433 is generally not less than 1 meter, in order to ensure the rigidity of the connecting rod 433, the connecting rod 433 may be a hollow tube, the periphery of the connecting rod 433 is provided with a rib, the frame 230 is provided with a guide groove extending along the up-down direction, the rib is cooperatively connected with the guide groove, and the rib not only has the function of reinforcing the rigidity of the connecting rod 433, but also has the guiding function through cooperation with the guide groove, i.e. the rib can be used as a guide block at the same time.
In this embodiment, the change of the direction of the transmission of force is achieved by two wedge blocks abutting against each other. Referring to fig. 5, both wedge blocks include inclined planes which are gradually inclined downward along the front-rear direction, when the spindle 433 drives the second wedge block 435 to move backward, the first wedge block 434 is gradually moved downward under the action of gravity by itself under the cooperation of the inclined planes, and since the first wedge block 434 is connected with the locking pin 420 through the rigid link 433, the locking pin 420 is synchronously moved downward when the first wedge block 434 moves downward, thereby unlocking the door leaf 200. In this embodiment, the transmission mechanism 430 is simplified, mechanical parts are reduced, and the installation efficiency is improved by using the wedge with the inclined surface as a main member for changing the direction of the transmission force. Meanwhile, the wedge block can be made of wear-resistant high polymer materials, so that the service life of the wedge block is prolonged.
In addition, to enhance the self-locking capability of the locking pin 420, the transmission mechanism 430 further includes a return spring 436, where the return spring 436 is installed in the base 432, and one end of the return spring 436 abuts against the inner wall of the base 432, and the other end abuts against the second wedge 435. Normally, the spring force provided by the return spring 436 causes the second wedge 435 to have a tendency to move forward, thereby preventing the downward movement of the first wedge 434 and thus avoiding the inadvertent unlocking of the door leaf 200. When the door needs to be unlocked, the pressing block 410 is pushed by force or the handle 440 is pulled by force, so that the main shaft 431 and the second wedge 435 are driven to move backward against the elastic force of the return spring 436, and the first wedge 434, the connecting rod 433 and the locking pin 420 are driven to move downward, so that the door leaf 200 is unlocked.
By adjusting the return spring 446 to provide a proper spring force, the pressing block 410 can have a good damping feel during unlocking, and the operation feel is improved. Meanwhile, proper spring force can also play a good self-locking role. In order to adjust the self-locking force, it can also be realized by setting the inclination angle of the inclined plane.
In some use scenarios, people located indoors do not want people outside, and then need to avoid people outside entering by back locking on the inner side. As described above, in the present embodiment, the main shaft 431 realizes the synchronous linkage between the handle 440 and the pressing block 410, that is, the pressing block 410 and the handle 440 move synchronously when unlocking. To function as a counter lock, it is necessary to perform an operation indoors, preventing an outdoor person from operating the pressing block 410 to unlock the lock pin 420.
In order to achieve the above-mentioned functions, in this embodiment, the transmission mechanism 430 is optimized, specifically, referring to fig. 5, further as a preferred embodiment, the spindle 431 is cylindrical, the pressing block 410 is sleeved with the front end of the spindle 431, the second wedge 435 is also sleeved with the spindle 431, that is, the spindle 431 can freely rotate around the axis of the spindle 431 relative to the pressing block 410, the second wedge 435 and the base 432, the handle 440 is fixed at the rear end of the spindle 431, and the handle 440 can also rotate relative to the base 432 due to the fact that the handle 440 is fixed with the spindle 431, in addition, a locking block 437 is fixed on the peripheral wall of the spindle 431, a stop wall is provided on the base 432, and a through slot penetrating front and back is provided on the stop wall, the locking block 437 corresponds to the through slot. Specifically, the locking block 437 and the through groove are configured such that the locking block 437 can pass through the through groove in the front-rear direction when the locking block 437 is integrally formed with the through groove, and the locking block 437 is held against by the holding wall when the locking block 437 is rotated, thereby preventing the locking block 437 from moving back and forth.
The door lock mechanism 400 also has a counter locking function through the above structural optimization. The pressing block 410 can only move along the front-back direction under the limitation of the through hole of the first panel 210, the handle 440 can be connected with the frame 230 through the main shaft 431, the handle 440 can also rotate around the axis of the main shaft 431 in addition to moving along the front-back direction, when the handle 440 rotates, the handle 440 can synchronously drive the locking block 437 on the main shaft 431 to rotate, the handle 440 can be provided with two stations, when the handle 440 is positioned at the first station, the locking block 437 can correspondingly pass through the groove, at the moment, the main shaft 431 can smoothly move along the front-back direction, namely, an outdoor person can push the pressing block 410 by force, so that the door can be unlocked, and when the handle 440 is positioned at the second station, the locking block 437 can not correspond to the through groove any more, at the moment, if the outdoor person pushes the pressing block 410 by force, the main shaft 431 cannot move backwards because the locking block 437 is abutted with the stop wall, so that the door lock of the main shaft 431 cannot be opened, so that the anti-locking function of the door can be realized.
Of course, in order to increase the strength of the back locking, the locking blocks 437 may be provided in a plurality of pieces, for example, 3 to 4 locking blocks 437 may be provided at equal intervals on the outer circumference of the main shaft 431, and of course, the corresponding through grooves are also in one-to-one correspondence with the locking blocks 437. In addition, in order to facilitate the indoor person to intuitively see whether the door lock is unlocked, an indication block may be provided on the handle 440 and the second panel 220. By means of the indicating block it is known whether the handle 440 is in the first or second position. Meanwhile, further, a marble may be disposed on the base 432, and two arc-shaped pits may be disposed on the outer circumference of the spindle 431, the pits corresponding to positions of the marble, the two pits corresponding to two stations of the handle, respectively. Because the marble has certain elasticity, when marble and pit correspond, can play certain spacing effect, utilize the marble to provide certain damping for the rotation of handle 440, improve the operation feel of handle 440. For example, when the handle 440 is in the first or second position, the marble just snaps into the pit and the handle cannot be easily rotated. When the handle 440 needs to be rotated, the marble is separated from the pit and is abutted against the outer end surface of the main shaft 431 until the marble enters another pit, and at the moment, the marble enters the pit again, so that resistance is provided for rotation of the handle. People can use the handle more conveniently through the change of the damping of the operating handle or whether the handle rotates in place.
In other embodiments, a second door lock mechanism may be provided on the indoor side, by means of which the counter-locking of the door leaf is achieved.
In this embodiment, the transmission mechanism 430 mainly uses the cooperation of two wedge blocks to realize the motion transmission between the main shaft and the connecting rod, and in other embodiments, the force transmission can also be realized by a gear rack mode. For example, the transmission mechanism 430 may include a first rack, a second rack, and a transmission gear, where the front-back movement of the spindle is converted into a linear movement of the first rack, and the first rack transmits the movement to the second rack through the transmission gear, and the second rack drives the link to move. Besides the gear rack, the transmission mechanism can also be a worm gear, a crank-link mechanism and the like.
As previously described, since the transmission mechanism 430 includes the return spring 436, the spring force provided by the return spring 436 automatically ejects the locking pin 420 upward in the absence of an external force. That is, in the absence of external force, when the door leaf 200 is not in the closed state, the latch 420 is obtrusive on the top of the door leaf 200, and if the door leaf 200 needs to be closed, the obtrusive latch 420 may collide with the door frame 100, so that the door leaf 200 is not closed. To overcome the above-mentioned disadvantages, referring to fig. 4, further as a preferred embodiment, the upper end of the locking pin 420 is provided with a guide slope, and the inside of the door frame 100 is provided with a guide slope corresponding to the guide slope. The lock pin 420 can be automatically introduced into the lock base 120 by using the guide inclined surface and the guide inclined surface. When the door is closed, the guide inclined surface is firstly contacted with the guide inclined surface of the door frame 100, then the guide inclined surface can force the guide inclined surface to move downwards, namely, the guide inclined surface forces the lock pin 420 to move downwards, so that the lock pin 420 avoids the door frame 100, and after the lock pin 420 moves to a position corresponding to the lock seat 120, the lock pin 420 is ejected upwards again under the action of the return spring 436, so that the locking of the door leaf 200 is realized. In addition, the guide slope also serves to facilitate entry of the locking pin 420 into the lock base 120.
Furthermore, in order to improve the indoor privacy, the hinge 300 is configured to drive the door leaf 200 to close automatically, i.e. the door leaf 200 closes automatically under the action of the hinge 300 in the absence of external force. In order to achieve the above function, a torsion spring may be provided in the hinge 300, and the torsion spring may be used to provide a force for locking the door to the door leaf 200. In addition, by arranging the first magnet block on the side of the door leaf 200 and arranging the second magnet block corresponding to the first magnet block in the door frame 100, the door leaf 200 and the door frame can be better self-locked by utilizing the two magnets which are attracted to each other. When the door leaf 200 is opened at a large angle, the two magnets are far apart and the force is small, but the force of the torsion spring is large, and when the door leaf 200 is opened at a small angle, the two magnets are near apart and the force of the torsion spring is large. The torsion of the torsion spring and the attractive force of the magnet are used for adaptively adjusting the acting force of the automatic door closing, so that a better door leaf 200 automatic door closing function can be achieved.
For convenient operation, the installation height of the traditional door handle is about 110cm, but a plurality of children with the age of 2-3 years can reach the installation height. As a further improvement of the above technical solution, the range of the installation height of the pressing block 410 from the ground is 130cm to 150cm. By setting the pressing block higher than the normal door lock handle, accidental opening by a child can be effectively prevented.
