[0002] An insulator is a special insulating control component that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles. Gradually, many disc-shaped insulators were hung at one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramics, which is called an insulator. Publication number: CN211828309U discloses an insulator, including a protection component, an insulator body, and an installation component. A parallel component is movably installed at the top of the insulator body. An insulating wire penetrates through the inside of the protection component. A lower steel foot is fixedly installed at the bottom of the insulator body, and an installation component is movably arranged at the bottom of the lower steel foot. In the utility model, by movably installing a parallel component at the top of the insulator body, the insulator body can be isolated by using a connecting rod, and then the connecting nut is rotated to drive the upper connecting plate to move up and down. Then, the upper pressing block and the lower pressing block are used in cooperation to limit the insulating wire. The gap between the insulator body and the parallel component protects the line and enables the product to be used more durably with a longer service life. Then, the positioning hole is used in cooperation with an external positioning bolt to install the support feet on the power equipment, which is convenient for the staff to carry out maintenance and repair. However, in the process of using the above technology, it is generally directly installed on the telegraph pole, which is not convenient for adjustment, there is no specific adjustment device, it is not convenient for distance adjustment, which affects the use effect of the device, reduces the work efficiency of the staff, and reduces the flexible usability of the device, so it needs to be improved.

A lower limit plate 6 is fixedly installed on the surface of the slider 5, an internal thread interface 7 is fixedly installed on the surface of the lower limit plate 6, an upper limit plate 9 is fixedly installed at the bottom end of the insulator body 8, an external thread joint 10 is fixedly installed on the bottom surface of the upper limit plate 9, and the external thread joint 10 is threadedly connected inside the internal thread interface 7. The lower limit plate 6 is slidably connected inside the chute 2, and the upper limit plate 9 presses the lower limit plate 6 inside the chute 2, enabling the insulator body 8 to be fixed on the slider 5 by threaded rotation, and then adjusting its position by rotating the bidirectional lead screw 4, ensuring the stability and reliability of the insulator during use. A protective cover 11 is fixedly installed on the surface of the mounting plate 1, a bolt 17 is inserted into the side surface of the protective cover 11, a screw hole 16 is opened on the side surface of the mounting plate 1, and the positions of the screw hole 16 and the bolt 17 correspond to each other, making the installation of the protective cover 11 more stable and also facilitating the disassembly and reinstallation of the protective cover 11, providing convenience for the maintenance and repair of the insulator. A limit block 14 is fixedly installed on the inner side of the protective cover 11, a limit groove 15 is opened on the surface of the mounting plate 1, and the cooperation use of the limit block 14 and the limit groove 15 can effectively prevent the performance degradation or damage of the protective cover 11 caused by position deviation during use or installation. A notch 12 is opened on the surface of the protective cover 11, an elastic soft pad 13 is inserted into the notch 12, the elastic soft pads 13 are symmetrically distributed on both sides of the insulator body 8, and the elastic soft pads 13 are made of polyurethane foam, improving the buffering performance between the insulator and the contact object and reducing the damage to the insulator caused by vibration.

[0025] Working principle: When the distance between insulators needs to be adjusted, first remove the protective cover 11 from the surface of the mounting plate 1, then rotate the bidirectional lead screw 4 so that the bidirectional lead screw 4 rotates inside the slider 5. Subsequently, the slider 5 can move inside the adjustment groove 3, so that the slider 5 can drive the insulator body 8 to move on the mounting plate 1, facilitating the operator to adjust the gap between the insulators and making the operation convenient. When the insulator body 8 needs to be maintained, only need to disassemble the external thread joint 10 from the internal thread interface 7, then the insulator body can be removed from the surface of the slider 5, improving the maintenance efficiency of the insulators by the operator.
