[0026] Specifically, when the user needs to connect the fastener with the rope, the second knob 13 and the threaded rod 14 are rotated, because the threaded rod 14 surface is screw connected with the moving piece 17, and the moving piece 17 is slidably connected between the connecting seat 2, when the threaded rod 14 rotates, the moving piece 17 will slide along the connecting seat 2 under the screw transmission, the moving piece 17 sliding towards the rope direction can compress and fix the rope, so as to realize the quick connection of the fastener and the rope, if need to release the connection, reverse rotation second knob 13, make threaded rod 14 reverse, and moving piece 17 will slide away from the direction of rope, loosen the fixing of the rope, realize the locking and release of the rope, meet the requirement of quick connection and disassembly under different scenes.
[0027] With reference to Figure 4 The connecting seat 2 surface is fixedly connected with a connecting piece 4, and the first roller 5 is rotatably connected in the connecting piece 4.
[0028] Specifically, when the buckle is connected with the rope and the traction operation is performed, the first roller 5 can rotate with the movement of the rope during the traction process, and the direct wear between the connecting piece 4 and the rope is reduced by replacing the sliding friction with the rolling friction, thereby prolonging the service life of the rope and the buckle and reducing the resistance during traction.
[0029] With reference to Figure 4 , the connecting piece 4 is internally provided with a second roller 6, and the two ends of the second roller 6 are rotatably connected with the connecting piece 4.
[0030] Specifically, the double rolling support structure is formed by adding the second roller 6, which further disperses the pressure received by the rope, so that the rope can be in contact with and rolled by the first roller 5 and the second roller 6 during the traction process, thereby further reducing the friction loss and better maintaining the straight motion trajectory of the rope.
[0031] With reference to Figure 1 , the inside of the shell 1 is provided with a steel wire rope 7, one end of the steel wire rope 7 is fixedly connected with the winding wheel 12, and the other end of the steel wire rope 7 is fixedly connected with a pull ring 8.
[0032] Specifically, the steel wire rope 7 can be directly wound or unwound by the rotation of the winding wheel 12, so as to flexibly adjust the extension length of the steel wire rope 7 to adapt to the demand for traction distance in different use scenarios, and the pull ring 8 facilitates the user to quickly connect the steel wire rope 7 with external equipment.
[0033] With reference to Figure 4 , the surface of the moving piece 17 is fixedly connected with a plurality of limiting blocks 15, and the plurality of limiting blocks 15 are slidably connected with the connecting seat 2.
[0034] Specifically, the sliding cooperation of the limiting block 15 and the connecting seat 2 provides a clear guide path for the movement of the moving piece 17, ensures that the moving piece 17 can only slide linearly in the preset direction under the driving of the threaded rod 14, avoids the rotation or deviation of the moving piece 17 during the threaded transmission process, and prevents the moving piece 17 from being moved excessively to cause the moving piece 17 to fall off.
[0035] With reference to Figure 2 , the surface of the shell 1 is rotatably connected with a first knob 3, and the first knob 3 is fixedly connected with the worm 10.
[0036] Specifically, by rotating the first knob 3, the worm 10 can be directly driven to rotate synchronously, and the rotation of the first knob 3 is transmitted to the worm wheel 11 through the meshing transmission characteristics of the worm 10 and the worm wheel 11, so as to drive the winding wheel 12 coaxially arranged with the worm wheel 11 to rotate, realizing the winding or releasing operation of the steel wire rope 7. Meanwhile, the meshing of the worm 10 and the worm wheel 11 has a self-locking function, which can automatically lock the position of the steel wire rope 7 after the winding wheel 12 stops rotating, preventing the steel wire rope 7 from sliding by itself due to external force, and improving the safety and stability of the fastener in the traction process.
[0037] With reference to Figure 3 The surface of the moving piece 17 is fixedly connected with a locking piece 9, and the locking piece 9 is rotatably connected with a third roller 16.
[0038] Specifically, when the moving piece 17 is slidably connected with the connecting seat 2 through the limiting block 15 and compresses the rope, the third roller 16 can be in contact with the surface of the rope and rotate with the rope, so as to replace the sliding friction between the locking piece 9 and the rope with rolling friction, reduce the wear of the rope during locking, and the rotation of the third roller 16 can adapt to the dynamic displacement of the rope in the traction process, avoiding the deformation of the rope or the jamming of the locking piece 9 due to rigid extrusion, so that the locking piece 9 can stably compress the rope to realize reliable fixation, and can reduce the resistance through the rolling of the third roller 16 when the rope is stressed, improving the flexibility and protection of the locking assembly.
[0039] Working principle: when the user needs to use the convenient steel wire traction rope fastener, if the length of the steel wire rope 7 needs to be adjusted, the first knob 3 on the surface of the shell 1 is rotated, the first knob 3 drives the worm 10 fixedly connected therewith to rotate, the rotation of the worm 10 drives the worm wheel 11 to rotate, and the worm wheel 11 drives the winding wheel 12 fixedly connected therewith to rotate, so that the winding wheel 12 winds or unwinds the steel wire rope 7 wound thereon, realizing the adjustment of the length of the steel wire rope 7, and the meshing of the worm 10 and the worm wheel 11 has a self-locking function, which can prevent the steel wire rope 7 from sliding by itself.
[0040] When the fastener needs to be connected with the rope, the second knob 13 is rotated, the second knob 13 drives the threaded rod 14 to rotate, the threaded rod 14 is threadedly connected with the moving piece 17, and the moving piece 17 is slidably connected with the connecting seat 2 through the limiting block 15, so that the rotation of the threaded rod 14 drives the moving piece 17 to slide along the connecting seat 2, the moving piece 17 drives the locking piece 9 to approach the rope and compresses the rope through the third roller 16, realizing the connection of the fastener with the rope, and the rope can be loosened by reversely rotating the second knob 13.
[0041] In the traction process, the first roller 5 and the second roller 6 in the connecting piece 4 are in rolling contact with the rope, reducing friction loss and maintaining the straight motion trajectory of the rope, and the pull ring 8 at the end of the steel wire rope 7 is convenient for connecting with external equipment.
