Detachable lock nut

Abstract

The invention discloses a detachable lock nut which comprises a nut body, a gasket and a spacer. A receding groove is formed in the gasket, the spacer is located below the gasket, an elastic piece is arranged on the spacer, the elastic piece is located in the receding groove of the gasket, the upper end of the elastic piece extends to the position above the gasket, the nut body is located above the gasket, and a ratchet corresponding to the upper end of the elastic piece is arranged on the bottom face of the nut body. The detachable lock nut has the advantages that a good anti-loosening effect is guaranteed, meanwhile, the nut further has a detachable function, and the detachable lock nut can be conveniently and repeatedly used.

Description

technical field [0001] The present invention relates to the technical field of nuts, more specifically to the technical field of anti-loosening nuts. Background technique [0002] The anti-loosening nut is a nut with an anti-loosening function. The anti-loosening methods adopted by the anti-loosening nut in the prior art mainly include mechanical anti-loosening, riveting anti-loosening, friction anti-loosening and structural anti-loosening, etc. Among them, Friction anti-loosening is the most widely used anti-loosening method. This method generates a positive pressure that does not change with the external force between the lock nut pairs to generate a frictional force that can prevent the lock nut pairs from rotating relative to each other. This kind of positive pressure can be achieved by compressing the lock nut pair axially or in two directions at the same time, such as using anti-slip washers, and the current common anti-slip washers generally improve the anti-slip effe...

[0002] The anti-loosening nut is a nut with an anti-loosening function. The anti-loosening methods adopted by the anti-loosening nut in the prior art mainly include mechanical anti-loosening, riveting anti-loosening, friction anti-loosening and structural anti-loosening, etc. Among them, Friction anti-loosening is the most widely used anti-loosening method. This method generates a positive pressure that does not change with the external force between the lock nut pairs to generate a frictional force that can prevent the lock nut pairs from rotating relative to each other. This kind of positive pressure can be achieved by compressing the lock nut pair axially or in two directions at the same time, such as using anti-slip washers, and the current common anti-slip washers generally improve the anti-slip effect by setting anti-slip teeth on their surface, so the anti-loosening The effect is not very ideal, and it cannot adapt to the use occasions that have high requirements for anti-loosening performance. Although some anti-loosening nuts with anti-loosening structures can have a good anti-loosening effect at present, these anti-loosening nuts are installed It cannot be disassembled afterwards, or it is very difficult to disassemble, and it is not convenient for the repeated use of the anti-loosening nut
