Although the wires are limited and pressed and fixed by the limiting grooves opened on the driven roller and the active roller, so as to adapt to wires of different sizes, different numbers of cables need to be built when the cables are built. The device cannot fix different numbers of cables according to the actual needs of the users, which increases the difficulty of the users' work. Therefore, an anti-entanglement aid in the construction of transmission and distribution lines is proposed to solve the above problems. Utility Model Content

After pressing the connecting block downward, the elastic potential energy of the reset spring will cause the two guide assemblies to clamp the cable, thereby effectively preventing the cable from being entangled, making the whole more practical.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 In this embodiment, the anti-entanglement aid in the construction of power transmission and distribution lines includes a protective box 1, a handle 2 is fixed on the top of the protective box 1, and a sponge pad is covered on the outer surface of the handle 2. Guide holes 10 are opened on the front and back sides of the protective box 1. Through the set guide holes 10, the cables can pass through the interior of the protective box 1. The left and right side walls of the inner cavity of the protective box 1 are slidably connected with a fixed frame 3. The left and right sides of the fixed frame 3 are fixed with extension rods slidably connected to the protective box 1. The outer surface of the extension rod is fixed with an extension block slidably connected to the protective box 1. Through the set extension rod and extension block, the sliding of the fixed frame 3 can be more stable, and the fixed frame 3 is not easily separated from the protective box 1.

[0033] In addition, a plug block 11 is fixed to the top of the fixing frame 3, and a slot compatible with the plug block 11 is opened on the inner top wall of the protective box 1. The set plug block 11 can be plugged into the protective box 1 to fix the fixing frame 3, so that the distance between the two guide components 6 can be maintained. A connecting rod 4 that passes through the outside of the protective box 1 is fixed to the top of the fixing frame 3, and a connecting block 5 is fixed to the top of the connecting rod 4.

[0034] Furthermore, a guide assembly 6 is provided inside the fixing frame 3 and inside the protective box 1. The guide assembly 6 is used to guide the wires. Two return springs 7 are fixed inside the fixing frame 3. A fixing rod 8 that passes through the outside of the fixing frame 3 is fixed to the bottom of the return spring 7. A fixing block 9 fixed to the protective box 1 is fixed to the bottom of the fixing rod 8.

[0035] In general, after the two guide components 6 clamp the cables, when the cables are subsequently pulled, the guide components 6 will rotate inside the protective box 1 and the fixing frame 3, thereby effectively improving the efficiency of pulling the cables and preventing the cables from being tangled.

[0036] See also Figures 2 to 3 The guide assembly 6 in this embodiment includes a rotating block 601, a guide block 602, four stabilizing rods 603, four positioning blocks 604 and four positioning springs 605. The two rotating blocks 601 are rotatably connected to the fixed frame 3 and the protective box 1 respectively. A stabilizing block 12 is fixed to the right side of the bottom rotating block 601, and the stabilizing block 12 is rotatably connected to the protective box 1. By setting the stabilizing block 12, the rotation stability of the rotating block 601 can be effectively improved, thereby making the whole more stable.

[0037] In addition, the rotating block 601 is fixed to the guide block 602, and the rotating block 601 is a square block. The front of the top guide block 602 and the back of the bottom guide block 602 are both provided with square grooves adapted to the rotating block 601. The rotating block 601 is a square block, so that when the guide block 602 rotates, it will drive the rotating block 601 to rotate together, thereby effectively ensuring the stability of the overall rotation. The outer surface of the guide block 602 is provided with a guide groove, and a friction pad is fixed in the groove of the guide groove. The guide groove is provided to guide the cable, and the friction pad is provided. The pad can effectively increase the friction between the cable and the guide block 602. The interior of the rotating block 601 is fixed to the stabilizing rod 603. The outer surface of the stabilizing rod 603 is slidably connected to the positioning block 604. Sliding blocks are fixed on the left and right sides of the positioning block 604. A sliding groove slidably connected to the sliding block is provided inside the rotating block 601. Through the setting of the sliding block, the sliding of the positioning block 604 inside the rotating block 601 is more stable. The positioning block 604 is plugged into the guide block 602, and the positioning block 604 and the rotating block 601 are fixed with a positioning spring 605.

[0038] In general, by pressing the positioning block 604, the positioning block 604 can be slid into the interior of the rotating block 601. At this time, different guide blocks 602 can be conveniently replaced according to the number of cables to be built, and the disassembly and assembly of the guide block 602 is very efficient, thereby effectively improving the overall practicality.

[0039] The working principle of the above embodiment is:

[0040] By pulling the connecting block 5 upward, the connecting rod 4, the fixing frame 3 and the top guide assembly 6 are moved upward, and the plug block 11 on the fixing frame 3 is plugged into the protective box 1, thereby creating a certain distance between the two guide assemblies 6. At this time, the cable can be passed through the guide hole 10 through the protective box 1 and between the two guide assemblies 6. By pressing the connecting block 5 downward, the connecting rod 4, the fixing frame 3 and the top guide assembly 6 are moved downward, and the plug block 11 loses connection with the protective box 1. Therefore, under the prestressed action of the reset spring 7, the top fixing frame 3 and the guide assembly 6 are moved downward, so that the two guide assemblies 6 clamp the cables, thereby effectively preventing the cables from being entangled. When the guide block 602 is replaced with a guide block 602 with a corresponding number of guide grooves, the positioning block 604 is pressed to allow the rotating block 601 to slide to the inside of the guide block 602. After the positioning block 604 moves to a position matching the guide block 602, the positioning spring 605 that accumulates elastic potential energy will push the positioning block 604 to connect with the guide block 602, thereby completing the fixation of the guide block 602. The overall structure is simple, and different numbers of cables can be built, making the overall structure more practical.
