Description

Technical Field

[0001] This utility model relates to the field of hardware components, specifically a self-locking and anti-loosening high-strength nut. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It is an essential component in all manufacturing machinery. Based on the material, nuts are classified into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). The utility model application CN201621338285.0 discloses an integrated anti-loosening nut, comprising a nut body and an annular elastic locking plate. The annular elastic locking plate is disposed on the upper end of the nut body and is an integral structure with the nut body. The annular elastic locking plate is bent towards the threaded inner side of the nut body and forms an annular groove with the nut body. The inner diameter of the annular elastic locking plate is smaller than the inner diameter of the threaded portion of the nut body, or the annular elastic locking plate and the threaded portion of the nut body have a slight axial or radial misalignment. Compared with the prior art, the annular elastic locking plate of this integrated anti-loosening nut is an integral structure with the nut body, which is convenient to manufacture and process, and has reliable performance. It also solves the problem of easy loosening of the split structure in the prior art. However, this nut still has the following defects in use: traditional nut structures usually have poor self-locking structures, which are prone to loosening, resulting in relatively unstable subsequent locking. Moreover, the stability of conventional locking structures is poor, and the stability of tightening the nut is poor. Utility Model Content
