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.

[0018] Example: Refer to Figure 1-3 A positioning bracket for high-voltage transmission wires in an electrical cabinet comprises a positioning bracket body 1, a bracket groove 2 is provided on the positioning bracket body 1, a first bonding layer 3 is provided in the bracket groove 2, two movable grooves 4 are provided on the inner walls of the bottom sides of the two movable grooves 4, a splint 6 is movably installed in the two movable grooves 4, an inner chamber 7 is provided in the two splints 6, and an insert block 8 is installed in the two inner chambers 7 through a clamping elastic force adjustment mechanism, the clamping elastic force adjustment mechanism comprises a circular plate 9, a connecting rod 10 and a spring 11, a circular plate 9 is movably installed in the inner chamber 7, one end of the connecting rod 10 is fixedly installed on one side of the circular plate 9, and the other end of the connecting rod 10 movably passes through the outside of the splint 6, and one side of the circular plate 9 is fixed One end of the spring 11 is installed, and the other end of the spring 11 is fixedly installed on the top inner wall of the inner chamber 7, so as to realize the movable adjustment of the plug block 8 by clamping the elastic force adjustment mechanism; one end of the two plug blocks 8 are respectively plugged into the corresponding sockets 5, and the two clamping plates 6 are provided with a second bonding layer 12 on the side close to each other, and the positioning bracket body 1 is provided with a mounting mechanism, which includes a mounting seat 13 and a mounting hole 14. One end of the positioning bracket body 1 is fixedly installed with a mounting seat 13, and a plurality of mounting holes 14 are opened on the mounting seat 13, so that the staff can install the mounting seat 13 on the pressure-bearing part of the electrical cabinet by using bolts. At this time, the straight-line distance from the upper frame slot 2 of the positioning bracket body 1 to the electrical cabinet is greater than 25 cm.

[0019] Furthermore, the two movable grooves 4 are symmetrically arranged, and the movable grooves 4 are arranged in a convex structure, which facilitates the sliding of the clamping plate 6 in the movable grooves 4.

[0020] Furthermore, the two clamping plates 6 are symmetrically arranged, and the sides of the two clamping plates 6 that are close to each other are arranged in an arc-shaped structure, so that the two clamping plates 6 can clamp and fix the high-voltage transmission wire.

[0021] Furthermore, the number of the second bonding layers 12 is set to two, and the first bonding layer 3 and the second bonding layer 12 are both made of rubber material. The high-voltage transmission wire is clamped and wrapped by the first bonding layer 3 and the two second bonding layers 12, thereby increasing the friction force at the contact parts between the first bonding layer 3 and the two second bonding layers 12 and the high-voltage transmission wire, and reducing the shaking of the high-voltage transmission wire during the clamping and fixing process.

[0022] When in use: install the mounting base 13 on the pressure-bearing part of the electrical cabinet by using bolts. At this time, the straight-line distance from the upper frame slot 2 of the positioning bracket body 1 to the electrical cabinet is greater than 25 cm. By pulling the two connecting rods 10 outward, the two circular plates 9 slide in the corresponding inner chambers 7 respectively. At this time, the two springs 11 are deformed and compressed by force. At this time, the two plug blocks 8 are recovered to the corresponding clamping plates 6, and then the high-voltage transmission wire is placed in the upper frame slot 2 of the positioning bracket body 1. After that, the two clamping plates 6 are adjusted to slide close to each other in the corresponding movable slots 4, so that the two clamping plates 6 clamp and fix the high-voltage transmission wire. At this time, the two second bonding layers 12 are respectively bonded to the surface of the high-voltage transmission wire, which increases the friction between the two clamping plates 6 and the high-voltage transmission wire, and reduces the shaking of the high-voltage transmission wire during the clamping and fixing process. Then, the two connecting rods 10 are loosened, and under the elastic force of the two springs 11, the two plug blocks 8 are respectively inserted into the corresponding sockets 5, thereby limiting and fixing the positions of the two clamps 6, and thus clamping and fixing the high-voltage transmission wire on the positioning bracket body 1. Therefore, the high-voltage transmission wire is clamped and fixed on the positioning bracket body 1 by adjusting the two clamps 6, and the high-voltage transmission wire is clamped and wrapped by the first bonding layer 3 and the two second bonding layers 12, thereby increasing the friction between the first bonding layer 3 and the two second bonding layers 12 and the high-voltage transmission wire. The shaking of the high-voltage transmission wire during the clamping and fixing process is reduced, thereby ensuring that the high-voltage transmission wire maintains a safe distance from the electrical cabinet while the high-voltage transmission wire will not shake, thereby avoiding the occurrence of short circuit or discharge accidents.
