Abstract

The invention provides a locking nut. The locking nut comprises a hex nut body, a connecting body, a locking body and a protective cover. The connecting body is arranged above the hex nut, the outer wall of the connecting body is provided with a thread, the inner wall of the protective cover is provided with a mounting flange, the mounting flange includes a mounting part and a driving part, the inner wall of the mounting part is provided with a thread, and the connecting body is cooperatively in threaded connection with the mounting part; the locking body is arranged above the connecting bodyand cooperates with the driving part, the driving part controls the locking body to be retracted inward in the radial direction, the relative rotation between the nut and a bolt can be prevented, correspondingly the purpose of locking is achieved, and the problem of a poor rust-proof effect of the nut due to exposure in the air for a long time can be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to a lock nut. 【Background technique】 [0002] Nuts are fasteners that have internal threads and are used in conjunction with bolts, which have internal threads. The traditional anti-loosening method of nuts is usually to add a washer under the nut to increase the friction force to prolong the fastening life of the nut. The friction force that can be increased by this conventional method is far from enough, and it is easy to fail. The maintenance method is to apply anti-rust oil or paint on the bolts and nuts to prevent them from rusting, but the anti-rust oil or paint applied on them will dissolve and lose, which will cause environmental pollution and require regular maintenance. The maintenance cost is increased, so a lock nut is proposed. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a lock nut ...
