As shown in fig. 1 to 9, an embodiment of the present invention provides a cable fixing clip, including:
the base 100 is provided with a through hole 102 for the cable 101 to pass through, a plurality of rotating pieces 200 are arranged in the through hole 102 at intervals along the circumferential direction, and the moving speed of the cable 101 along the through hole 102 is positively correlated with the rotating speed of the rotating pieces 200;
a brake assembly 300 provided on the rotary member 200, the brake assembly 300 being switchable between a release position and a braking position such that the rotary member 200 is switched between a corresponding free rotation state and a locking state;
the cable 101 is forced to move the cable 101 along the through hole 102, the brake assembly 300 is at the release position or is switched from the brake position to the release position under the action of the force so that the cable 101 starts to move along the through hole 102, and the force is removed, and the brake assembly 300 is switched from the release position to the brake position so as to limit the cable 101 from moving along the through hole 102.
The base 100 is installed at a fixed point of the cable 101, a force is applied to the cable 101 to enable the cable 101 to have a trend of moving along the through hole 102, at the moment, the brake assembly 300 is at a release position, the cable 101 starts to move and drives the rotating piece 200 to rotate to start installing the cable 101, the force is removed, at the moment, the brake assembly 300 is switched to the brake position from the release position, the rotating piece 200 is synchronously switched to a locking state, at the same time, the cable 101 is limited to move, the cable 101 is fixedly installed, and at the moment, the force is applied to the cable 101, at the moment, the brake assembly 300 is switched to the release position from the brake position, the cable 101 starts to move and drives the rotating piece 200 to rotate to start detaching the cable 101. The installation and the disassembly process of the cable 101 can be realized by controlling the movement of the cable, the construction process is simple and convenient, the construction efficiency is improved, the construction period is shortened, and the engineering progress is ensured, thereby meeting the severe requirements of efficient and standardized construction.
The base 100 may be integrally formed or formed by combining two components, so as to facilitate the processing and installation of the rotor 200, the brake assembly 300, and other structures. When the base 100 is used, the base 100 is directly fixed on the passing point when the cable 101 is laid through the bolts, and compared with the prior art that the upper part and the lower part of the base 100 are required to be combined and installed, the process of installing the base 100 is more convenient.
The rotating member 200 is a cylinder, but may be a sphere, and the axis of the through hole 102 is perpendicular to the rotation axis of the rotating member 200. The outer surface of the cable 101 has a certain elasticity, and when the cable 101 moves along the through hole 102, the outer surface of the cable 101 is in close contact with the outer surface of the rotating member 200 to drive the rotating member 200 to rotate, so that the speed of the cable 101 moving along the through hole 102 is equal to the linear speed of the outer surface of the rotating member 200 when rotating, and when the rotating member 200 is in the locked state, the movement of the cable 101 along the through hole 102 is also limited. In addition, the rotating member 200 can also restrict the rotation of the cable 101 in the circumferential direction thereof, and a plurality of, preferably three, rotating members 200 are provided at intervals in the circumferential direction of the through hole 102 to achieve the support of the cable 101 and the guiding of the movement of the cable 101 along the through hole 102.
The force applied when the cable 101 is detached is greater than the force applied when the cable 101 is installed, because when the cable 101 is installed, the brake assemblies 300 corresponding to each base 100 are in a release state, the cable 101 can be moved along the through holes 102 by applying smaller first force to the cable 101, and when the cable 101 is detached, the brake assemblies 300 corresponding to each base 100 are in a brake state, the cable 101 generally has certain elasticity, larger second force needs to be applied to one end of the cable 101, so that one end of the cable 101 deforms in the length direction until the brake assemblies 300 corresponding to the first base 100 are switched from the brake position to the release position, and at the moment, only the larger second force needs to be applied to the cable, so that the brake assemblies 300 corresponding to each base 100 can be sequentially switched from the brake position to the release position, and finally the cable 101 is detached from all the bases 100.
Preferably, referring to fig. 3, the brake assembly 300 includes a clamping groove 301 and a sliding plate 302, the inner wall of the through hole 102 is provided with a mounting groove 303 for mounting the rotating member 200, the inner wall of the mounting groove 303 is provided with a plurality of clamping grooves 301 at intervals along the circumferential direction thereof, and the rotating member 200 is provided with a plurality of sliding plates 302 at intervals along the circumferential direction thereof;
when slide plate 302 slides into engagement with card slot 301, brake assembly 300 is in the braking position, and when slide plate 302 slides out of engagement with card slot 301, brake assembly 300 is in the release position.
The installation groove 303 is an arc groove, and the corresponding arc is a major arc, so that the rotating member 200 protrudes into the through hole 102 after the rotating member 200 is installed in the installation groove 303, but in order to save space, the protruding distance of the rotating member 200 needs to be limited. In addition, the number of the clamping grooves 301 is greater than that of the sliding plates 302, and the clamping grooves 301 are formed at two ends of the mounting groove 303 corresponding to the arc, and are half of the clamping grooves 301, so that the sliding plates 302 protruding into the through holes 102 can slide into the half of the clamping grooves 301.
Wherein, the rotating member 200 is provided with a sliding slot, and the sliding plate 302 is slidably disposed in the sliding slot, and the sliding slot is preferably disposed along a radial direction of the rotating member 200.
Of course, other structures may be adopted to implement the function of the brake assembly 300, so that the rotating member 200 can be switched between a corresponding free rotation state and a locking state, for example, a brake shoe capable of clamping and releasing the rotating member 200 is arranged on the outer circumferential surface of the rotating member 200, for example, a brake disc is arranged on the end surface of the rotating member 200, friction braking force is generated on the rotating member 200 when the brake disc contacts the rotating member 200, for example, a conductor disc is arranged on the end surface of the rotating member 200, an electromagnet is arranged near the conductor disc, and when the rotating member 200 drives the conductor disc to rotate, a static magnetic field generated by the cutting electromagnet generates an opposite magnetic field in the conductor disc, so that braking torque on the conductor disc and the rotating member 200 is generated.
Preferably, a cavity is formed in the rotating member 200, a flywheel 304 coaxial with the rotating member 200 is disposed in the cavity, and a plurality of elastic protrusions 305 are disposed on the flywheel 304 at intervals along the circumferential direction thereof;
the elastic protrusion 305 is pushed by the inner side of the sliding plate 302 to rotate the flywheel 304, or the outer side of the sliding plate 302 is separated from the clamping groove 301, the inner side of the sliding plate 302 passes over the elastic protrusion 305, and the elastic protrusion 305 pushes the inner side of the sliding plate 302 to be clamped with the clamping groove 301 when the acting force is removed.
When the cable 101 is installed, a small first force is applied to the cable 101 to enable the cable 101 to have a tendency to move along the through hole 102, at this time, the brake assembly 300 is in a release position, that is, the outer side of the sliding plate 302 is separated from the clamping groove 301, the rotating member 200 is in a free rotation state, the cable 101 can start to move and drive the rotating member 200 to rotate, and the inner side of the sliding plate 302 contacts and pushes the elastic protrusion 305, so that the originally static flywheel 304 starts to rotate along with the rotating member 200 until the cable 101 passes through the through hole 102, as shown in fig. 3;
After the cable 101 passes through all the through holes 102 on the base 100, the acting force applied to the cable 101 is cancelled, the cable 101 stops moving, the rotating member 200 synchronously stops rotating, the flywheel 304 continues rotating due to inertia, the elastic protrusion 305 on the flywheel 304 contacts and pushes the inner side of the sliding plate 302, so that the sliding plate 302 far away from the cable 101 slides to the outer side thereof to be clamped with the clamping groove 301, the brake assembly 300 is switched to a brake position from a release position, the rotating member 200 synchronously switches to a locking state and cannot rotate, and the sliding plate 302 close to the cable 101 slides to the outer side thereof to further squeeze the cable 101 so as to limit the cable 101 to move, and thus the cable 101 passing through the through hole 102 is fixed, as shown in fig. 9, and the process is automatically completed in a short time;
When the cable 101 is detached, a larger second force is applied to the cable 101 to enable the cable 101 to have a trend of moving along the through hole 102, at this time, the brake assembly 300 is in a braking position, so that the rotating member 200 has a trend of rotating but cannot rotate until the sliding plate 302 slides inwards, so that the outer side of the sliding plate 302 is separated from the clamping groove 301, meanwhile, the inner side of the sliding plate 302 presses the elastic protrusion 305 to deform the elastic protrusion, until the inner side of the sliding plate 302 passes over the elastic protrusion 305, the brake assembly 300 is switched from the braking position to the release position, the rotating member 200 is synchronously switched to a free rotation state, the cable 101 starts to move and drives the rotating member 200 to rotate, and the originally stationary flywheel 304 is also pushed to start rotating until the cable 101 passes through the through hole 102 to complete the detachment process of the current base 100.
Referring to fig. 3 and 6, the rotating member 200 is a cylindrical structure with a cavity, two ends of the rotating member are closed and are coaxially provided with a fixed shaft, two ends of the fixed shaft are rotatably disposed in the mounting groove 303, and the fixed shaft extends into the cavity of the rotating member 200. The flywheel 304 is fixedly provided with mounting plates 316 at both ends for providing the elastic protrusions 305, and the flywheel 304 and the mounting plates 316 are rotatably mounted on the fixed shaft.
Wherein the number of resilient protrusions 305 preferably corresponds to the number of slides 302.
Wherein, the bulge size, bulge shape and elastic restoring force of the elastic bulge 305 can be selected. When the outer side of the sliding plate 302 is not blocked by the clamping groove 301, that is, the brake assembly 300 is at the release position, the rotating member 200 drives the sliding plate 302 to rotate, the inner side of the sliding plate 302 can stir the elastic protrusion 305 to rotate the flywheel 304, at this time, the acting force exerted by the inner side of the sliding plate 302 on the elastic protrusion 305 is smaller than the elastic restoring force, the elastic protrusion 305 keeps itself unchanged without deformation, and when the outer side of the sliding plate 302 is blocked by the clamping groove 301, that is, the brake assembly 300 is at the brake position, the outer side of the sliding plate 302 slides out along the inclined surface 314 of the clamping groove 301, and the acting force exerted by the inner side of the sliding plate 302 on the elastic protrusion 305 is larger than the elastic restoring force, so that the elastic protrusion 305 is extruded to deform, and the inner side of the sliding plate 302 passes over the elastic protrusion 305.
It should be noted that, the contact portion between the sliding plate 302 and the sliding groove may be provided with an anti-slip layer, that is, the resistance of the sliding plate 302 sliding along the sliding groove is moderately increased, so as to avoid the sliding plate 302 sliding freely in the sliding groove, that is, the sliding plate 302 sliding into the clamping groove 301 or sliding out of the clamping groove 301 under the action of the centrifugal force generated by the rotation of the rotating member 200 or the gravity, so that the sliding action of the sliding plate 302 along the sliding groove is only caused by the elastic protrusion 305 and the inclined surface 314 of the clamping groove 301.
Of course, other arrangements for driving the sled 302 to retract synchronously may be employed. For example, a linear motor is disposed on the rotating member 200, and the output end of the linear motor drives the sliding plates 302 to slide and independently control, and for example, a micro motor is disposed on the rotating member 200, and a gear is disposed on the output end of the micro motor, and each sliding plate 302 is mounted on a rack, and the gear is meshed with the rack, so that the sliding plates 302 can synchronously stretch.
Preferably, referring to fig. 3, 4, 7 and 8, the flywheel 304 is sleeved with an elastic ring 306, a plurality of elastic protrusions 305 are formed on the elastic ring 306 at intervals, and a middle part 307 is arranged between two adjacent elastic protrusions 305, wherein the middle part 307 is used for isolating the two adjacent elastic protrusions 305 from each other.
All the elastic protrusions 305 belong to the whole elastic ring 306, which can be understood as a cam with the elastic protrusions 305, the cam rotates to squeeze the inner side of the sliding plate 302 to drive the sliding plate 302 to slide along the sliding groove, and a recess is formed between the adjacent elastic protrusions 305, that is, the elastic protrusions 305 and the recess are alternately arranged, when the inner side of the sliding plate 302 is located in the recess, the outer side of the sliding plate 302 is separated from the clamping groove 301, that is, the brake assembly 300 is located at the release position.
The middle piece 307 is a rod body and at least three rod bodies are arranged between the two mounting plates 316, and the elastic rings 306 are wound on the three rod bodies in an inner-outer alternating manner, so that two adjacent elastic protrusions 305 are isolated from each other, that is, when one elastic protrusion 305 deforms, the deformation amount of the elastic protrusion 305 adjacent to the elastic protrusion is not affected. Of course, the intermediate member 307 may be a fixing member such as a fixing nail or a rivet, and the elastic ring 306 is directly fixed to the outer circumferential surface of the flywheel 304, and the elastic protrusions 305 are formed between two adjacent fixing members, so that the mutual influence caused when the two adjacent elastic protrusions 305 deform can be avoided.
Preferably, the direction in which the elastic protrusion 305 is deformed is the radial direction of the flywheel 304.
Therefore, when the inner side of the sliding plate 302 extrudes the elastic bulge 305 from any side of the elastic bulge 305, the corresponding elastic bulge 305 can only deform along the radial direction of the flywheel 304, so that the deformation of the elastic bulge 305 keeps a certain rule.
Of course, the direction of deformation of the elastic protrusion 305 may be other directions, for example, when the inner side of the sliding plate 302 is pressed from one side of the elastic protrusion 305, the elastic protrusion 305 deforms toward the other side.
Preferably, the elastic projection 305 includes two oppositely disposed elastic plates 308.
The two elastic plates 308 are oppositely arranged, one end of each elastic plate 308 close to the flywheel 304 is widely spaced, and the other end of each elastic plate 308 is smoothly connected with the other end of each elastic plate, so that the two elastic plates 308 are obliquely arranged, a sliding rod 309 is arranged at the joint of the two elastic plates 308, sliding grooves 310 for sliding the sliding rod 309 are formed in the opposite surfaces of the two mounting plates 316, and the sliding grooves 310 are arranged along the radial direction of the mounting plates 316, so that the elastic protrusions 305 can deform only along the radial direction of the flywheel 304 to avoid the inner side of the sliding plate 302.
Of course, the elastic protrusion 305 may have other structures, for example, the contact surface between the elastic protrusion 305 and the inner side of the sliding plate 302 is an arc surface, a deformation cavity is formed in the elastic protrusion, and the elastic protrusion has an elastic deformation function and is independently disposed on the outer circumferential surface of the flywheel 304, and the shape of the deformation cavity may be selectively disposed so that the corresponding elastic protrusion 305 can only deform along the radial direction of the flywheel 304.
Preferably, referring to fig. 5, the elastic plate 308 is provided with a guide 311, and the guide 311 deforms the elastic plate 308 along its length.
When the elastic plate 308 is pressed on the inner side of the sliding plate 302, the elastic plate 308 can only deform along the length direction, so that the elastic plate 308 is prevented from being pressed to generate bending or deformation in other directions.
Preferably, the elastic plate 308 is a corrugated plate having a plurality of bending grooves 312, and the dimension of the bending grooves 312 along the length direction of the elastic plate 308 is positively correlated with the length of the elastic plate 308.
Under the extrusion action of the inner side of the sliding plate 302, the elastic plate 308 deforms, and the size of the bending groove 312 changes accordingly, it can be understood that the larger the elastic plate 308 is, the larger the size of the bending groove 312 in the length direction of the elastic plate 308 is, the shorter the elastic plate 308 is, and the smaller the size of the bending groove 312 in the length direction of the elastic plate 308 is until it disappears.

After the cable 101 passes through all the through holes 102 on the base 100, the acting force applied to the cable 101 is cancelled, the cable 101 stops moving, when the rotating piece 200 synchronously stops rotating, the flywheel 304 continues rotating due to inertia, the elastic plate 308 contacts the inner side of the sliding plate 302, the inner side of the sliding plate 302 is positioned in the bending groove 312 at the corresponding position, the elastic plate 308 deforms to reduce the size of the bending groove 312, the elastic plate 308 synchronously pushes the sliding plate 302 to slide outwards, the outer side of the sliding plate 302 far away from the cable 101 is clamped with the clamping groove 301, the brake assembly 300 is switched from the release position to the brake position, the rotating piece 200 is synchronously switched to the locking state and cannot rotate, the cable 101 is further extruded by the outer side of the sliding plate 302 close to the cable 101, so that the cable 101 is limited to move, and the cable 101 passing through the through hole 102 is fixed, as shown in fig. 9, and the process is automatically completed in a short time;
when the cable 101 is detached, a larger second force is applied to the cable 101 to enable the cable 101 to have a trend of moving along the through hole 102, at the moment, the brake assembly 300 is in a braking position, so that the rotating member 200 has a trend of rotating but can not rotate, for the sliding plate 302 positioned in the clamping groove 301, the sliding plate 302 slides inwards, so that the outer side of the sliding plate 302 is separated from the clamping groove 301, the inner side of the sliding plate 302 presses the elastic plate 308 to deform, the size of the bending groove 312 at the corresponding position is reduced to the inner side of the sliding plate 302, the inner side of the sliding plate 302 passes over the elastic protrusion 305, and other sliding plates 302 protruding into the through hole 102 slide into half of the clamping groove 301 at the edge of the mounting groove 303 and slide along the inclined surface 314 of the half of the clamping groove 301 to be separated from the same, the brake assembly 300 is switched from the braking position to the releasing position, the rotating member 200 is synchronously switched to a free rotating state, the cable 101 starts to move and drives the rotating member 200 to rotate, and the flywheel 304 is also pushed to be stationary until the cable 101 starts rotating through the through hole 102 to complete the detachment process of the current base 100.

Preferably, referring to fig. 3 and 9, the card slot 301 has two oppositely disposed inclined surfaces 314, the inclined surfaces 314 enabling the outer side of the slide plate 302 to slide out of the card slot 301.
When the cable 101 is detached, a larger force is applied to the cable 101 to cause the cable 101 to have a tendency to move along the through hole 102, and at this time, the brake assembly 300 is in the braking position, so that the rotating member 200 has a tendency to rotate but cannot rotate, and the outer side of the sliding plate 302 slides out of the clamping groove 301 through the inclined surface 314, that is, the sliding plate 302 slides inward, so that the outer side of the sliding plate 302 is separated from the clamping groove 301.
Wherein, the inclined plane 314 forms an included angle with the radial direction of the mounting groove 303, and the included angle is in the range of [30 °,60 ° ], preferably 45 °, so that when a larger second force is applied to the cable 101, the outer side of the sliding plate 302 is convenient to slide out of the clamping groove 301, and when the force applied to the cable 101 is smaller than the second force, the outer side of the sliding plate 302 is always located in the clamping groove 301, so that the fixation of the cable 101 is more stable.
