Problems solved by technology

The structure of this traditional serrated washer is relatively complicated, and the manufacturing process is difficult, resulting in high cost
[0004] In addition, because there is no tight engagement between fasteners such as screws or bolts and the serrated washer, there will still be looseness between the fastener and the serrated washer or the fixed object, or even fall off

Abstract

The invention discloses a lock washer and the lock fastener component, wherein, the lock washer comprises a main body of the washer and a through hole arranged at the middle of the main body, wherein, a plurality of notches communicated with the through hole are distributed on the main body of the washer along radial direction by means of centrosymmetry; the edge of the main body of the washer at one side end of the communication part of each notch and the through hole is folded towards the surface end to form a raised locking part; the edge of the main body of the washer on the other side end is folded towards the internal end to form a raised locking part. The lock fastener component comprises a threaded fastener and the lock washer matched with the threaded fastener. The invention has the advantages of looseness prevention under high temperature and high-frequency vibration impact, better backward-resistant and locking effect, simpler processing technology, lower production cost, and repeated disassembly and application.

Description

technical field [0001] The invention belongs to the technical field of mechanical fastening connections, and in particular relates to an anti-loosening washer and an anti-loosening fastening assembly. Background technique [0002] The strong components of the existing fasteners generally use traditional bolts, nuts and washers. The fastening structure is composed of bolts inserted in the connectors, and nuts are tightened and fixed, or springs, washers or bolts are added. And other accessories prevent bolts and nuts from loosening. Due to their simple structure, low cost, good fastening effect under normal circumstances, and standardization can be implemented, the shape and structure of this fastening component have not changed for a hundred years. Nevertheless, this fastening structure assembly, due to its structural defects, is easy to loosen bolts and nuts, thus causing accidental stories to happen. The reason is that in some specific structures, fixed mechanical structu...
