Problems solved by technology

[0003] 1. Although it can improve the friction between the threads, under frequent vibration, the threads between the nut and the bolt will still loosen slowly, and it is impossible to completely prevent loosening;
[0004] 2. The more the nut is tightened, the better the anti-loosening effect will be, but it will make it

Abstract

The invention provides an anti-loosening fastening assembly, and belongs to the field of mechanical fasteners. The problem that an existing fastener is poor in anti-loosening effect is solved. The anti-loosening fastening assembly comprises a bolt and a nut and further comprises an anti-loosening gasket; the longitudinal section of the anti-loosening gasket is of a right triangle structure; the nut is provided with an extrusion mechanism; the extrusion mechanism comprises an extrusion groove located on the inner wall of the bottom end of the nut, and the groove wall of the extrusion groove isprovided with telescopic grooves; telescopic columns and compression springs are arranged in the telescopic grooves; an extrusion sleeve is arranged in the extrusion groove, the outer wall of the extrusion sleeve is provided with a rotation groove, and the inner side groove all of the rotation groove is of a sawtooth structure in the circumferential direction of the rotation groove; the extrusionmechanism further comprises an annular plate-like extrusion plate, the bottom surface of the extrusion plate is of an annular inclined surface structure, and the inner edge of the extrusion plate is fixed to the bottom end of the extrusion sleeve; and the groove wall of the extrusion groove and the outer wall of the extrusion sleeve are smooth surfaces, and the bottom surface of the extrusion plate and the top surface of the anti-loosening gasket are rough surfaces. The anti-loosening fastening assembly can further improve the anti-loosening effect.

Description

technical field [0001] The invention belongs to the technical field of mechanical fasteners and relates to an anti-loosening fastening component. Background technique [0002] The use of fasteners for the connection of mechanical devices is a common connection method, usually including bolts and nuts that are screwed together. Because of its convenient disassembly and simple structure, it is widely used in mechanical equipment. In order to prevent mechanical vibration from causing connection Loosening, the most common method is to put gaskets on the bolts, so that the gaskets are clamped between the nuts and the connected parts, and the gaskets are axially expanded and reset to increase the thread friction between the bolts and the nuts. So as to achieve the anti-loosening effect, but the use of gaskets for anti-loosening has the following defects: [0003] 1. Although it can improve the friction between the threads, under frequent vibration, the threads between the nut and...
