Problems solved by technology

[0002] The pin insulator includes a porcelain body and a metal post. The metal post is inserted into the groove of the porcelain body and bonded with an adhesive. During use, the metal post tends to expand, causing the groove of the porcelain body to burst and break the porcelain body. It will affect the later use of insulators

Embodiment 1

[0014] Such as figure 1 Shown: an anti-explosion pin type insulator, including a porcelain body 1, a screw column 2, and a nut 3, the lower end of the porcelain body 1 is provided with a groove 5, and the screw column 2 is inserted into the groove at the lower end of the porcelain body 1 In 5, an adhesive is used for bonding and connection, and the nut 3 is connected to the screw post 2 .

[0015] Further speaking, the nut 3 is welded with an annular cylinder 4 .

[0016] Further speaking, the diameter of the circular cylinder 4 is 2 mm larger than the edge diameter of the groove 5 at the lower end of the porcelain body 1 .

[0017] Furthermore, the material of the circular cylinder 4 is iron or aluminum alloy.

[0018] When the present invention is in use: the groove of the porcelain body and the screw column are bonded and fixed with an adhesive, the nut welded with the circular cylinder is connected with the end of the screw column, and the nut is turned to make the circu...

Abstract

An anti-explosion pin insulator, including a porcelain body, a screw post, and a nut, characterized in that: the lower end of the porcelain body is provided with a groove, and the screw post is inserted into the groove at the lower end of the porcelain body and bonded with an adhesive connected, the screw column is connected with a nut, the nut is welded with a ring cylinder, the diameter of the ring cylinder is greater than the edge diameter of the groove at the lower end of the porcelain body by 2mm, and the ring The material of the column body is iron or aluminum alloy, the nut has a confinement to the screw column, and the ring cylinder has a confinement to the groove of the porcelain body, double protection, preventing the expansion of the metal screw column from affecting the porcelain body, and avoiding damage to the later use and expenses influences.

Description

technical field [0001] The invention relates to the technical field of electric porcelain appliances, in particular to an explosion-proof pin-type insulator. Background technique [0002] The pin insulator includes a porcelain body and a metal post. The metal post is inserted into the groove of the porcelain body and bonded with an adhesive. During use, the metal post tends to expand, causing the groove of the porcelain body to burst and break the porcelain body. It will affect the later use of insulators. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide an anti-explosion pin insulator with simple structure, low manufacturing cost, firm fixation, and effective prevention of expansion of the metal cylinder to burst the ceramic body. [0004] The technical solution of the present invention is: an anti-explosion pin type insulator, including a porcelain body, a screw column, and a nut. Adhes...
