Description

Lock nut for automobile assembly

technical field

The utility model relates to the technical field of nuts, in particular to a locknut for automobile assembly.

Background technique

A locknut is a nut that is screwed together with a bolt for fastening. When the existing locknuts are used to lock parts with ordinary nuts and bolts, in order to prevent the nuts from loosening, generally first Put the spring washer on the bolt and then tighten the nut on the bolt, and rely on the elastic force of the spring washer to increase the friction between the nut and the matching thread of the bolt, thereby preventing the nut from loosening. When the strength is too high, the gasket will be deformed to a certain extent, resulting in poor effect of the locknut, and the locknut will even lose its function directly. Moreover, the existing locknut is inconvenient to disassemble and requires a large torque to carry out turn.
