[0002] Insulators are a special type of insulating control, a device that is installed between conductors at different potentials or between conductors and grounded structures and can withstand voltage and mechanical stress. Insulators are mainly used to support and fix conductors to ensure their stable position in overhead lines. They can be combined with hardware to firmly fix the conductors on poles and towers, thus supporting and suspending the conductors. Insulators play a vital role in overhead lines, as they not only ensure the stable suspension of conductors, but also effectively prevent current leakage and ensure the normal operation of the power system.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the overhead line insulator installation structure, by rotating the rotating head, enables the rotating head to rotate the second gear by adjusting the rack, enables the second gear to rotate the first gear through the connecting rod, enables the displacement rack connected to one side of the first gear to move, thereby enabling the position of the movable seat set at the bottom to be adjusted, thereby facilitating the installation of insulators of different sizes, and pulls the pull rod to rotate the ring, so that the locking rod can clamp the inserted cable after moving, thereby preventing the cable from loosening after installation.

[0016] 1. The insulator installation structure for overhead lines. When the insulator installation structure is used to install insulators in overhead lines, it is usually not easy to install insulators of different sizes. The rotating head is engaged by a hexagonal tool, so that the threaded rod can move the adjusting rack, so that the adjusting rack can rotate the second gear, so that the second gear can rotate the first gear through the connecting rod, so that the displacement rack connected to one side of the first gear can move the movable seat, so that the movable seat can restrict the guide rod placed on the top of the fixed seat after movement, so that the guide rod can be quickly fixed, and the position of the movable seat can be adjusted, so that the insulator installation structure is more convenient for installing insulators of different sizes in overhead lines;

[0017] 2. The insulator installation structure for overhead lines, when the insulator installation structure is installing the insulator, it is usually not easy to tighten the cable, making the insulator inconvenient to use after installation. The cable can be passed through the locking groove, and the pull rod can be pulled, so that the pull rod can pull the connected fixed block when moving, so that the fixed block can pull the connected ring, so that the ring can rotate inside the ring groove, and the ring can push the displacement block through the guide groove provided inside when rotating, so that the displacement block can move, so that the displacement block can move the locking rod connected to the top when moving, so that the locking rod can clamp the inserted cable after moving, thereby preventing the cable from being easily loosened after installation;

[0018] 3. The insulator installation structure for overhead lines, when the insulator installation structure is installing the insulator, the second locking bolt connected to the lifting ring is usually exposed to the outside for a long time, so that the second locking bolt is easily corroded in the environment of sun and rain, so that the second locking bolt is easy to cause its own performance to decline, so that the second locking bolt is easy to break when locked, so that the fixed insulator is easy to fall off. After the second locking bolt is installed, the fixed rod is rotated, and then the movable rod is pulled so that the movable rod can be extended, and then the protective cover is placed on the top of the second locking bolt, and then the movable rod is loosened so that the protective cover connected to the movable rod can be moved downward, and the second locking bolt can be locked, so that the second locking bolt can be prevented from being exposed to the sun and rain for a long time at a high place, so that the lifting ring is not easy to fall after installation, and the insulator installation structure can be relatively stable after the insulator is installed.

After the second locking bolt 32 is installed, the fixing rod 35 is rotated so that the fixing rod 35 can drive the connected movable rod 34 to rotate, and then the movable rod 34 is pulled so that the movable rod 34 can be extended. The movable rod 34 is stretched so that the limiting spring 37 can be squeezed when it moves, and then the protective cover 33 is placed on the top of the second locking bolt 32.
