Abstract

The invention relates to an anti-looseness and antitheft nut. The anti-looseness and antitheft nut comprises a nut body of a circular-truncated-cone-shaped structure. The outer side face of the nut body is a polished face. A through hole penetrating through the upper bottom face and the lower bottom face is formed in the nut body in the axial direction and is a cylindrical through hole. The cylindrical through hole is divided into an upper through hole section and a lower through hole section. The upper through hole section and the lower through hole section are connected in series. An elasticbush is arranged on the inner wall of the upper through hole section. An inner thread is arranged on the inner wall of the lower through hole section. At least three notches are formed in the bottomarea of the nut body. Each notch is formed in the generatrix direction of the nut body. The notches extend from the outer surface of the nut body to the inner surface of the nut body. The anti-looseness and antitheft nut is good in reliability, high in antitheft coefficient and good in anti-looseness effect.

Description

technical field [0001] The invention belongs to the field of mechanical parts, in particular to a nut, in particular to an anti-loosening and anti-theft nut. Background technique [0002] As we all know, a nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is an essential element for all production and manufacturing machinery, and its application is very wide. [0003] At present, nuts are usually made of carbon steel, stainless steel, non-ferrous metals (such as copper), and their material costs are high, especially for high-cost nuts. If they are installed outdoors, some criminals will think of stealing them and selling them as scraps for money. In addition, the existing traditional nuts also have the disadvantage of being easy to loosen. [0004] Therefore, it is the subject of the present invention to propose an anti-loosening anti-theft nut. SUMMARY OF THE INVENTION [0005] The main purpose of the present application is to provi...
