Abstract

The invention provides a locknut, and relates to the technical field of mechanical anti-loose devices. The locknut comprises a first nut and a second nut; the first nut and the second nut are simultaneously fastened on the same bolt; one of the contact faces of the first nut and the second nut is an inclined plane; the horizontal end faces of the nuts abut against external workpieces; when the first nut and the second nut are coaxially arranged and abutted to each other, a gap with the angle is formed between the first nut and the second nut, the second nut continues to be twisted towards thedirection of the first nut, the eccentric magnitude is generated between the first nut and the second nut as the gap becomes smaller, and the eccentric magnitude is increased as the vibration force ofthe external workpieces increases, so that the loosening of the locknut is prevented. On the basis of ensuring the anti-loose effect, the locknut has simple processing process, low requirements on materials and tooling, and low processing cost, and the locknut is not affected by metal ductility and fatigue, and is more suitable for the needs of consumers.

Description

technical field [0001] The invention relates to the technical field of mechanical anti-loosening devices, in particular to an anti-loosening nut, an anti-loosening mechanism and an anti-loosening assembly. Background technique [0002] At present, the existing nuts have good fastening performance. But the anti-loosening property is not good. During the long-term use of parts, nuts and bolts will loosen differently. Only Japan Hadlock Industry Co., Ltd. produces the never loosening nut. The anti-loosening performance is the most excellent. Currently at the highest level in the world. However, such nuts with wedge heads and concave nuts are affected by metal ductility and fatigue, and the processing technology is cumbersome, and the requirements for materials and tooling are relatively high, and the cost is too high. The present invention guarantees the same anti-loosening performance as Hadlock. The cost is low, the process is simple, and the requirements for materials ...
