Abstract

The invention relates to an elastic locking component, an anti-loosening nut and an anti-loosening bolt nut fastener. The elastic locking component comprises an inner spring and an outer spring arranged on the outer portion of the inner spring in a sleeving manner. One end of the outer spring is connected with the same end of the inner spring through an inner and outer spring connecting portion. The turning direction of the outer spring is opposite to that of the inner spring. The anti-loosening nut is used for being assembled with a bolt and is provided with a nut body and the elastic lockingcomponent. The other end of the outer spring is connected with the nut body, and the inner spring can be pressed on and wound around a thread of the bolt. The anti-loosening bolt nut fastener is provided with a pre-tightening sleeve and the above anti-loosening nut. The structure is simple, and the locking performance is good; only the nut body is modified, and the bolt or a fastening workpiece does not need to be modified; and it can be guaranteed that the fastener has good work intensity, and engineering safety can be guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical fasteners, in particular to an elastic locking component, a lock nut and a lock bolt and nut fastener. Background technique [0002] At present, all walks of life are using more and more fasteners. For some fasteners that have been exposed to shock, vibration, and variable loads for a long time, the anti-loosening of nuts is particularly important. In the prior art, commonly used anti-loosening methods include frictional anti-loosening, mechanical anti-loosening and permanent anti-loosening, etc. These anti-loosening structures are inconvenient to disassemble, and correspondingly, the processing procedures are cumbersome and the cost is high; in addition, in the prior art , It is often necessary to obtain fasteners with slotted holes on the base or bolt and nut kits, which will reduce the strength of the fasteners and reduce the safety of the project. Contents of the invention [0003] The present inv...
