Anti-loosening anti-theft removal tool special for screw bolt

Abstract

A tool for assembling and disassembling a screw bolt structural body includes an assembling and disassembling body, a step cavity provided at the bottom inside the assembling and disassembling body upwards, a first step most close to the bottom of the assembling and disassembling body in the step cavity having shape thereof in accordance with the shape of the gasket, a second step above the first step in the step cavity having shape thereof in accordance with the shape of the screw bolt head and the screw nut, wherein the first step is in irregular circular shape. The tool is a special tool for the anti-loosening anti-theft screw bolt, and the anti-loosening anti-theft screw bolt comprises a screw nut, two gaskets, and a screw bolt.; Wedge-shape toothed oblique surfaces high on one edge and low on another edge is disposed on the bottom edge of the screw bolt head and the upper edge of the screw nut, having blocking surfaces formed at the joint positions between wedge-shape toothed oblique surfaces. An oblique surface correspondingly wedged to the wedge-shaped toothed oblique surfaces of the screw bolt head and the screw nut, having bearing surfaces formed on the joint positions between oblique surfaces. A panel strip or a salient point is provided on the other surface of the gasket which is in irregular circular shape. With the structure, the screw bolt is capable of complete anti-theft, and can be detached only by the special tool of the invention.

Description

technical field [0001] The invention relates to a special dismounting tool for a detachable anti-loosening and anti-theft bolt structure. Background technique [0002] As we all know, bolts, as basic parts for connecting various mechanical components and devices, are widely used in various mechanical equipment connected by flanges. According to the current domestic situation, the anti-theft of iron towers is all realized by using anti-theft bolts, so anti-theft lock nuts have been used all the time. Although the anti-theft lock nut has solved the problem of anti-theft, it brings great difficulties to transformation construction and emergency construction because it cannot be disassembled. Especially in 2008, when towers were covered with ice in a large area in the south, during the emergency project, since the anti-theft lock nuts could not be disassembled with tools, the bolts had to be cut off by gas cutting. Workers had to carry oxygen cylinders, acetylene gas cylinders,...

Although the anti-theft lock nut solves the problem of anti-theft, it brings great difficulties to reconstruction construction and emergency construction because it cannot be disassembled

Especially in 2008, when towers were covered with ice in a large area in the south, during the emergency project, since the anti-theft lock nuts could not be disassembled with tools, the bolts had to be cut off by gas cutting. Workers had to carry oxygen cylinders, acetylene gas cylinders, gas cutting guns or Machines and other equipment can be completed, seriously affecting the progress of emergency rescue
