[0002] Insulators are devices installed between conductors at different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress. Insulators are a special type of insulating control that can play an important role in overhead transmission lines. They are usually made of glass or ceramic, and are called insulators. Among them, electric porcelain insulators refer to those made of porcelain electrical insulating materials.

[0003] Commonly used porcelain insulators are installed with a bracket at the use position and fastened with bolts. However, they are exposed to the air for a long time, and the fastening parts will rust after long-term use. Once the porcelain insulator is damaged, it will affect the safe operation of the transmission line. It is difficult to disassemble it when it needs to be replaced, which makes it inconvenient for users to replace it. For this reason, we propose a conveniently replaceable anti-expansion and crack porcelain insulator to solve the above problems. Utility Model Content

A through hole 17 is opened on the upper surface of the mounting seat 1. The set through hole 17 can make the mounting block 12 conveniently inserted into the mounting seat 1 for easy use. By rotating the threaded screw 6, the square connecting plate 8, the transmission long rod 9 and the fixing plate 10 are moved outward under the action of the thread, and then the limiting long rod 11 is moved out of the mounting block 12 and the socket 13 under the fixing action of the fixing plate 10 and the limiting long rod 11, thereby releasing the limiting fixation of the bearing seat 2 and the main insulator 3, thereby achieving the purpose of facilitating their removal from the mounting seat 1 and realizing convenient disassembly when replacement is required.
