However, the above design has a high cost, and because the transmission structure is located inside the device and communicates with the complex external environment, it is easy to be corroded after a period of use, thereby affecting the later use, and it is not easy to maintain it. Utility Model Content

[0004] The utility model provides a wire rack based on power transmission engineering, which solves the problems of a wire rack based on power transmission engineering proposed in a Chinese patent with publication number CN218829013U, which has high cost, and because the transmission structure is located inside the device and communicates with the complex external environment, it is easy to be corroded after being used for a period of time, thereby affecting the later use, and it is difficult to maintain.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a wire rack based on power transmission engineering, comprising a vertically arranged wire pole, a bracket is fixed to one side of the upper end of the wire pole in the horizontal direction, a movable plate is arranged above the bracket, a fixed plate is slidably arranged on the movable plate, the bottom end of the fixed plate is spliced ​​with the upper end of the bracket, a plurality of mounting grooves evenly arranged along the horizontal splicing line are arranged at the splicing of the bracket and the fixed plate, a gap is arranged between the upper end of the bracket and the bottom end of the movable plate, and the gap height is large. At half the height of the mounting groove, an arc-shaped arm is fixed on one end of the movable plate close to the electric pole, and the arc-shaped arm is horizontally arranged along the outer wall curve of the electric pole, and the end of the arc-shaped arm away from the bracket is rotatably connected with a boss 1, and the boss 1 is fixed on the outer wall of the electric pole, and a positioning shaft is arranged on the rotation center line of the arc-shaped arm and the boss 1 and passes through the arc-shaped arm and the boss 1, and the other end of the arc-shaped arm is connected with a boss 2 by a bolt, and the boss 2 is fixed on the outer wall of the electric pole, and the movable plate is connected to the position between the two ends of the arc-shaped arm.

[0006] The beneficial effects of the utility model are as follows: the bolts connecting the arc arm and the second convex seat are removed, and then the arc arm is rotated on the first convex seat with the positioning axis as the center, so that the arc arm drives the movable plate and the fixed plate supported on the movable plate to rotate around the positioning axis to the side away from the bracket, thereby facilitating the fixing of several cables to the positions of several installation slots on the bracket respectively, and then the movable plate, the fixed plate and the arc arm are pulled back, and during the pulling back process, it is ensured that the fixed plate is lifted upward to avoid being stuck to the cable, and the arc arm and the second convex seat are fixed again with bolts, and then the fixed plate is moved downward to be spliced ​​with the bracket, and then different cables are classified and fixed in several installation slots. Through the above structure, not only is it easy to install cables, it is easy to organize cables, and the cables are stably fixed, but the realized structure is relatively simple, cost-saving, convenient for maintenance and long-term use.

The limiting nut is limited on the side of the movable plate away from the fixed plate, and two groups of the special-shaped groove, sliding column and limiting nut are arranged in parallel in the horizontal direction.

[0015] The beneficial effect of this improvement is that the fixed plate is lifted upward relative to the movable plate, and during the process the sliding column slides upward in the special-shaped groove, so that the bottom end of the fixed plate is higher than the height of the installed cable. Then, when the cable is installed on the bracket, the bottom end of the fixed plate will not get stuck on the cable when the fixed plate is rotated back, avoiding affecting the installation.

[0016] In order to facilitate the fixed plate to be supported on the movable plate at a raised height, so as to facilitate the installation operation;

[0017] As a further improvement of the above technical solution: the special-shaped groove is an inverted L-shaped groove formed by connecting a vertical groove and a transverse groove at the top, and the inner wall end of the transverse groove is concave downward.

[0018] The beneficial effect of this improvement is that the shape of the special-shaped groove allows the sliding column to first move upward and then move horizontally to one side during the sliding process, and fall back downward at the end of the horizontal movement, thereby restricting the sliding column to the end position of the special-shaped groove, and then supporting the fixed plate at the raised height, which is more conducive to installation operations.

[0019] In order to facilitate the manual operation of the fixed plate movement;

[0020] As a further improvement of the above technical solution: a protrusion is provided on an upper portion of a side of the fixed plate away from the movable plate.

[0021] The beneficial effect of this improvement is that it is easier to move the fixing plate by holding the protrusion.
