Problems solved by technology

[0002] There are still deficiencies in the existing nuts: 1. Nylon nuts. The temperature resistance of nylon is 120-250 degrees. If the temperature exceeds this temperature, the locking function will be lost; 2. The anti-theft nut adopts the steel ball anti-retraction structure. The plastic sleeve is installed in the nut, the purpose is to prevent the steel ball in the triangular groove in the threaded hole from falling out, but this kind of installation is very inconvenient, and the nut can only be moved forward and cannot be reversed at the beginning of assembly.
The above three kinds of nuts have a common disadvantage: the cooperation between the nut and the bolt produces a lot of friction at the beginning of installation, and it is not easy to screw in; A lot of iron filings fell, the connection is unreliable, and the practicability is poor

Abstract

The invention discloses a self-locking anti-disengagement nut which comprises a nut body. An anti-disengagement band is integrally arranged at one end of the nut body and axially provided with a self-locking groove. A self-locking conical face is integrally arranged at the end, close to the nut body, of the anti-disengagement band. The anti-disengagement band is sleeved with a lock pad. The middleof the lock pad is axially provided with a lock pad through hole. The end, away from the nut body, of the lock pad is axially provided with a positioning groove. The positioning groove communicates with the lock pad through hole. The nut body is locked through the cooperation of the lock pad and the self-locking conical face. By means of the technical scheme, the self-locking anti-disengagement nut is reasonable in structural design, simple in structure, convenient to install, reliable in connection, good in anti-disengagement performance, good in antitheft effect and high in practicability.

Description

technical field [0001] The invention relates to the technical field of nuts, in particular to a self-locking anti-loosening nut. Background technique [0002] There are still deficiencies in the existing nuts: 1. Nylon nuts. The temperature resistance of nylon is 120-250 degrees. If the temperature exceeds this temperature, the locking function will be lost; 2. The anti-theft nut adopts the steel ball anti-retraction structure. The plastic sleeve is fitted in the nut, the purpose is to prevent the steel ball in the triangular groove in the threaded hole from falling out, but this kind of installation is very inconvenient, and the nut assembly can only advance and cannot retreat at the beginning. 3. Metal cleat nuts and metal flattening (pressure point) nuts. The above three kinds of nuts have a common disadvantage: the cooperation between the nut and the bolt produces a lot of friction at the beginning of installation, and it is not easy to screw in; A lot of iron filings ...
