There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting hardware. In the early years, insulators were mostly used for electric poles, and gradually developed into a high-voltage electric wire connection tower with many disc-shaped insulators hung on one end.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides Figure 1-5 The anti-expansion and cracking electric porcelain insulator shown comprises a base 1;

[0030] A fixing block 6 is installed inside the base 1 and is used to support and assemble the electric porcelain insulator. A threaded column 2 is fixedly installed below the base 1.

[0031] An insulating umbrella 9 is fixedly mounted on the fixing block 6 and is used to assemble the insulating umbrella 9. A mounting groove 10 is provided on the outer surface of the insulating umbrella 9. A rubber ring 11 is sleeved inside the mounting groove 10. A reinforcing ring 12 is provided outside the rubber ring 11.

[0032] The fireproof layer 13 and the protective layer 14 are arranged inside the insulating umbrella 9 to prevent the insulating umbrella 9 from expanding and cracking;

[0033] The insulating head 23 is installed on the upper end of the insulating umbrella 9 and is used to install the electric porcelain insulator. A connecting strip 24 is fixedly installed above the insulating head 23. The reinforcing ring 12 is sleeved on the outside of the insulating umbrella 9, so that the reinforcing ring 12 can stabilize the insulating umbrella 9 and prevent the melting point of the insulating umbrella 9 from increasing and the internal pressure from expanding, thereby causing cracking. In addition, the installation groove 10 also makes it convenient for workers to install.

[0034] like Figure 1 and Figure 2 As shown, telescopic rods 3 are movably connected inside the two sides of the base 1, inner cavities are opened inside the two sides of the base 1, springs 4 are arranged inside the inner cavity and outside the telescopic rod 3, a docking column 5 is arranged at the inner center of the base 1, the base 1 is movably connected to the fixed block 6, a docking groove 7 is arranged inside the fixed block 6, and slots 8 are opened on the two side surfaces of the fixed block 6.

[0035] like Figure 1 and Figure 3 As shown, the insulating umbrellas 9 are arranged in three groups, and the outsides of the three groups of insulating umbrellas 9 are respectively sleeved with rubber rings 11 and reinforcement rings 12. The reinforcement rings 12 can improve the strength of the insulating umbrellas 9 and prevent them from bursting.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the material of the fireproof layer 13 is high-purity alumina, and the material of the protective layer 14 is insulating paint. Through the arrangement of the fireproof layer 13 and the protective layer 14, it has good heat resistance, wear resistance, and corrosion resistance, and can effectively prevent exposure to high temperatures in the sun and avoid cracking at high temperatures.

[0037] like Figure 1 , Figure 3 and Figure 5As shown, a connecting end 15 is fixedly installed at the lower end of the insulating umbrella 9, and sliding grooves 16 are provided on the two side surfaces of the connecting end 15. A socket end 17 is fixedly installed at the upper end of the insulating umbrella 9. By threadedly connecting the connecting end 15 below the insulating umbrella 9 with the socket end 17 above another group of insulating umbrellas 9, each insulating umbrella 9 can be disassembled individually, and the damaged part of each insulating umbrella 9 can be disassembled and replaced.

[0038] like Figure 5 As shown, a limiting groove 18 is provided on the upper end surface of the socket end 17, a protective sleeve 19 is movably provided above the socket end 17, a card slot 20 is provided on one side surface of the protective sleeve 19, a card block 21 is fixedly installed on the other side of the protective sleeve 19, and a limiting block 22 is fixedly installed on the lower end of the protective sleeve 19. After the connection between the connecting end 15 and the socket end 17, the protective sleeve 19 will limit the connection to improve the stability of the connection between the two.

[0039] The practical working principle of the present invention is as follows: first, the connection end 15 below each insulating umbrella 9 is threadedly connected with the socket end 17 above another group of insulating umbrellas 9, so that each insulating umbrella 9 can be assembled and disassembled separately. After the assembly is completed, the slider inside the protective sleeve 19 is aligned with the slide groove 16 outside the connection end 15, and the card groove 20 and the card block 21 on one side of the two groups of protective sleeves 19 are used for assembly and connection, and then the limiting block 22 below the protective sleeve 19 is aligned with the limiting groove 18 in the socket end 17, so as to protect the connection of the insulating umbrella 9 and enhance the stability, and then the lowest insulating umbrella 9 and the fixing block 6 are placed in the base 1, and at this time, the telescopic rods 3 on both sides of the base 1 are pulled first, and when the fixing block 6 and the docking groove 7 are docked in the docking column 5 in the base 1, the telescopic rod 3 is loosened and used. The external spring 4 plays a rebounding role, and the telescopic rod 3 rebounds and is inserted into the slots 8 on both sides of the fixing block 6, so as to assemble and fix the entire device, and then it is installed to the required position through the threaded column 2 under the base 1. When the electric porcelain insulator is used for a long time, the internal temperature will gradually increase. As the internal pressure expands, the reinforcing ring 12 is sleeved on the outside of the insulating umbrella 9, which can stabilize the insulating umbrella 9 and prevent the insulating umbrella 9 from increasing its own melting point and expanding the internal pressure, thereby causing expansion and cracking. At the same time, through the arrangement of the fireproof layer 13 and the protective layer 14, it has good heat resistance, wear resistance and corrosion resistance, can effectively prevent exposure to high temperature of the sun, and avoid expansion and cracking at high temperature. In this way, the use process of the anti-expansion and cracking electric porcelain insulator is completed.
