DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 3 The present application provides an embodiment: a cable bracket with adjustable tightening aperture, comprising a bracket 1, a round tube 2 is arranged on the top of the bracket 1, and the round tube 2 is convenient for the cable to pass through; the inner wall of the round tube 2 is provided with a plurality of slide grooves 3 along the circumference, and screws 4 are rotatably arranged in the plurality of slide grooves 3, and the screws 4 are assembled inside the slide grooves 3.

[0028] A transmission gear 5 is provided at one end of the screw rod 4, and a folding piece 6 is provided on the outer wall of the screw rod 4. The inner wall of the circular tube 2 is provided with clamping pieces 7 along the circumference, the number of which is corresponding to the number of the slide grooves 3. When the transmission gear 5 drives the screw rod 4 to rotate, the folding piece 6 folds and pushes the clamping piece 7 to move. At this time, the diameter of the cable tightening hole can be adjusted by synchronously contracting several clamping pieces 7.

[0029] The clamping member 7 is connected to the inner wall of the circular tube 2 by setting a first spring 8. The first spring 8 pulls the clamping member 7 to move and causes the clamping member 7 to always fit with the folding member 6. Therefore, when the folding member 6 is unfolded, the clamping member 7 loses its thrust. At this time, the first spring 8 pulls the clamping member 7 to return to its original position, thereby increasing the diameter of the cable tightening hole.

[0030] The threads at both ends of the screw rod 4 are in opposite directions, and a winding disk 41 is fixedly sleeved in the middle of the screw rod 4. When the screw rod 4 rotates, the folding member 6 is folded or unfolded. When the folding member 6 is folded, it pushes the clamping member 7 to move and reduce the diameter of the cable tightening hole. When the folding member 6 is unfolded, the first spring 8 pulls the clamping member 7 to reset and expand the diameter of the cable tightening hole.

[0031] The folding member 6 includes two internal threaded rings 61 and two folding plates 62. The two internal threaded rings 61 are respectively threadedly sleeved on the two ends of the screw rod 4. One end of the two folding plates 62 is hinged to the two internal threaded rings 61 respectively, and the other ends of the two folding plates 62 are hinged by a pin shaft. When the screw rod 4 rotates, the two internal threaded rings 61 move in opposite directions at the same time. When the internal threaded rings 61 move inward at the same time, the folding plates 62 fold and shrink, thereby pushing the clamping member 7 to move. When the internal threaded rings 61 move outward at the same time, the folding plates 62 unfold, and the clamping member 7 loses its thrust, and the clamping member 7 is pulled back to its original position by the first spring 8.

[0032] The clamping member 7 includes two movable rods 71 ​​and an arc plate 72. The two movable rods 71 ​​are symmetrically arranged on the outer wall of the arc plate 72. One end of the movable rod 71 away from the arc plate 72 is movably plugged into the circular tube 2. The first spring 8 is sleeved on the movable rod 71. One end of the first spring 8 is fixedly connected to the arc plate 72, and the other end of the first spring 8 is fixedly connected to the inner wall of the circular tube 2. The folding member 6 is used to facilitate the movement of the arc plate 72. At the same time, the two movable rods 71 ​​cooperate to increase the stability of the arc plate 72 when it moves, and the first spring 8 pulls the arc plate 72 to move and causes the arc plate 72 to always fit with the pin of the folding plate 62.

[0033] An annular groove 9 is provided on the inner wall of the circular tube 2, and a gear ring 10 is rotatably provided on the inner wall of the annular groove 9. The gear ring 10 meshes with the transmission gear 5. By rotating the gear ring 10, several transmission gears 5 are driven to rotate synchronously with the screw 4, and as the screw 4 rotates, the folding part 6 is folded and the clamping part 7 is pushed to move.

[0034] See the attached drawings in the specification Figure 1-2 A hollow ring 11 is fixedly provided on the inner side of the gear ring 10, and the hollow ring 11 is provided on the inner wall of the circular tube 2. The hollow ring 11 is provided to facilitate the operator to rotate the gear ring 10, and then the gear ring 10 facilitates the transmission gear 5 and the screw 4 to rotate.

[0035] The shape of the bracket 1 is T-shaped, and two auxiliary plates 12 are symmetrically hinged at the bottom of the cross plate of the bracket 1. The two auxiliary plates 12 are connected to the cross plate of the bracket 1 by setting a second spring 13 on one side facing the cross plate of the bracket 1. The second spring 13 facilitates the deflection of the auxiliary plates 12, so that the cooperation of the two auxiliary plates 12 facilitates the increase of the stability of the bracket 1 when supporting the cable.

[0036] The auxiliary plate 12 is hinged to the cross plate of the bracket 1 through a pin shaft, and a steel cable 14 is wound around the outer wall of the pin shaft. The end of the steel cable 14 away from the pin shaft passes through the round tube 2 and is wound around the winding disk 41. When the operator rotates the gear ring 10, it drives the transmission gear 5 and the screw 4 to rotate, causing the folding piece 6 to fold, and at the same time, the steel cable 14 is unwound. At this time, the auxiliary plate 12 loses the tension and pushes the auxiliary plate 12 to deflect through the second spring 13, causing the auxiliary plate 12 to unfold. When the operator rotates the gear ring 10 in the opposite direction, it drives the transmission gear 5 and the screw 4 to rotate in the opposite direction, causing the folding piece 6 to unfold, and at the same time, the steel cable 14 is wound. At this time, the auxiliary plate 12 is pulled upward by the steel cable 14 to deflect and cause the auxiliary plate 12 to fold and shrink.

[0037] Working principle: When using the cable bracket with adjustable tightening aperture, first insert the cable into the round tube 2, then drive several transmission gears 5 and the screw 4 to rotate synchronously by rotating the gear ring 10, and as the screw 4 rotates, the folding member 6 is folded and the clamping member 7 is pushed to move. At this time, the diameter of the cable tightening hole is adjusted by the synchronous contraction of several clamping members 7;

[0038] When the operator rotates the gear ring 10, the transmission gear 5 and the screw rod 4 rotate to cause the folding member 6 to fold, and at the same time, the steel cable 14 is unwound. At this time, the auxiliary plate 12 loses its tension and the auxiliary plate 12 is pushed to deflect by the second spring 13 to cause the auxiliary plate 12 to unfold;

[0039] When the operator rotates the gear ring 10 in the opposite direction, the transmission gear 5 and the screw rod 4 rotate in the opposite direction, causing the folding member 6 to unfold and the steel cable 14 to be wound up. At this time, the auxiliary plate 12 is pulled upward by the steel cable 14 to deflect and fold and shrink.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
