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-off nut, which comprises a nut body. An anti-off strip is integrally provided at one end of the nut body. A self-locking groove is axially arranged on the anti-off strip. The anti-off strip is close to the nut body. A self-locking tapered surface is provided at the end; the anti-off belt is covered with a lock pad, and a lock pad through hole is arranged axially in the middle of the lock pad, and a positioning recess is provided axially at the end of the lock pad away from the nut body The positioning groove communicates with the through hole of the lock washer; when the nut body is locked, the lock washer and the self-locking cone are locked together. The above-mentioned technical scheme has reasonable structural design, simple structure, convenient installation, reliable connection, good detachment prevention performance, good anti-theft effect and good 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 ...
