Problems solved by technology

[0002] During the inspection of transmission lines, it is often found that the tower materials on the line towers are stolen, which brings safety hazards to the safe operation of transmission lines, and brings great harm to national property and people's life safety.
In the prior art, an anti-theft nut with a built-in ball structure is often used. When this anti-theft nut is installed, the balls often fall off or the balls are broken, so that the nut loses the anti-theft function. The phenomenon that it cannot be unscrewed in reverse will cause the tower material to be unable to be fastened at the construction site

Abstract

The invention discloses an antitheft nut of a power transmission tower. The antitheft nut comprises a cylindrical head nut body. A left boss and a right boss which are in central symmetry relative tothe center of the top face are arranged on the cylindrical head top face of the cylindrical head nut body; and a left boss included angle is arranged on the upper right portion of the section of the left boss, a right boss included angle is arranged on the lower left portion of the section of the right boss, and the left boss included angle and the right boss included angle are equal. The antitheft nut is suitable or fastened connection of parts on the power transmission tower and can be screwed by a screwdriver, and mounting construction of the power transmission tower is facilitated; and when overhauled, the nut has to be loosened through a matched special tool and cannot be loosened by a common screwdriver and a common spanner, the parts of the power transmission tower can be effectively prevented from being stolen, and safe operation of a power transmission line is ensured.

Description

technical field [0001] The invention relates to an anti-theft nut for a power transmission tower. Background technique [0002] During the inspection of transmission lines, it is often found that the tower materials on the line poles and towers are stolen, which brings safety hazards to the safe operation of transmission lines, and brings great harm to national property and people's life safety. In the prior art, an anti-theft nut with a built-in ball structure is often used. When this anti-theft nut is installed, the balls often fall off or the balls are broken, so that the nut loses the anti-theft function. The phenomenon that it cannot be unscrewed in the opposite direction causes the tower material to be unable to be fastened at the construction site. Contents of the invention [0003] The purpose of the present invention is to provide a new type of anti-theft nut, which has a simple structure, is easy to process and manufacture, is more convenient to install when wor...
