[0025] During operation, due to the heavy weight of the insulator, the existing insulator is connected by a threaded rod, which is inconvenient to operate and requires the cooperation of multiple people for installation. Moreover, when the insulator is damaged and needs to be replaced, it is inconvenient to disassemble and replace it, resulting in inconvenience in disassembly and assembly. In the present scheme, in the initial test state, the spring 7 will always push the No. 1 ratchet bar 5 in the direction of the square sleeve 3, so that the No. 1 ratchet bar 5 is tightly attached to the side wall of the square sleeve 3, and the ratchet on the No. 1 ratchet bar 5 passes through the through groove 6 and is set in the square sleeve 3.

The other end of the heat dissipation aluminum fin 16 is penetrated and arranged on the outside of the fixed box 1, and a fixing seat 17 is installed on the fixed box 1. A flip buckle 18 is installed on the fixing seat 17 through a pin shaft. Fixed plates 19 are respectively installed on the same side of the fixing seat 17 and the flip buckle 18. Threaded holes are penetrated on the two fixing plates 19, and bolts 20 are arranged on the two fixing plates 19.

When the No. 2 ratchet bar 10 is installed in the square sleeve 3, the inclined surface of the ratchet teeth on the side of the No. 2 ratchet bar 10 will push the ratchet teeth of the No. 1 ratchet bar 5 into the through groove 6, and the ratchet teeth of the No. 1 ratchet bar 5 will squeeze the spring 7 in the opposite direction of the through groove 6 after being squeezed, so that the spring 7 will be squeezed and contracted. After the spring 7 contracts, the No. 1 ratchet bar 5 will slide on the No. 1 limiting rod 4, so that the ratchet teeth of the square sleeve 3 will contract into the through groove when the square sleeve 3 moves. The second ratchet bar 10 is inserted into the groove 6, and when the second ratchet bar 10 is gradually inserted upward, the ratchet teeth on the second ratchet bar 5 will push the ratchet teeth on the first ratchet bar 5 toward the side of the spring 7 in sequence. When the second ratchet bar 10 is inserted into place, the ratchet teeth on the side of the first ratchet bar 5 and the ratchet teeth on the side of the second ratchet bar 10 will mesh with each other under the action of the spring 7, so that the second ratchet bar 10 is fixed in the square sleeve 3, and the cooperation achieves the effect of facilitating installation. When it needs to be removed, it only needs to pull the anti-slip buckle 9, which will drive the first ratchet bar 5 through the second limit rod 8. The ratchet bar 5 moves in the opposite direction of the through slot 6, thereby separating the No. 1 ratchet bar 5 from the No. 2 ratchet bar 10, and making the No. 1 ratchet bar 5 slide on the No. 1 limiting rod 4. When moving, the No. 1 ratchet bar 5 will squeeze the spring 7 to the opposite side of the through slot 6 to shrink it, and after the ratchet teeth of the No. 1 ratchet bar 5 are separated from the ratchet teeth of the No. 2 ratchet bar 10, the No. 2 ratchet bar 10 can be taken out of the square sleeve 3, which achieves the effect of quick disassembly and assembly. Compared with traditional insulators, it is more convenient to install and effectively saves manpower.

When wind blows through the heat dissipation aluminum sheet 16, the temperature of the heat dissipation aluminum sheet 16 can be reduced, and then the temperature of the square sleeve 3 can be reduced through the heat dissipation aluminum sheet 16, and then the temperature of the No. 2 ratchet bar 10 can be reduced through the square sleeve 3, and at the same time, the temperature of the rod core 13 is jointly reduced under the action of the heat dissipation box 15. When installing, the operator only needs to set the fixing part on the fixing seat 17, and then flip the flip buckle 18 on the fixing seat 17, and then install the bolt 20 in the threaded holes of the two fixing plates 19 at the same time, and the fixing box 1 can be installed under the fixing part through the fixing seat 17 and the flip buckle 18, which cooperates to achieve the effect of improving the heat dissipation effect and effectively reduces the operating intensity of the operator.
