Description

High-performance lock nut for automobile

Technical Field

The utility model relates to the field of automobile accessories, in particular to a high-performance lock nut for an automobile.

Background

The locking nut is widely applied to the industries of machinery and the like, and the working principle of the locking nut is to adopt friction force between the nut and a bolt for self locking. But the reliability of such self-locking in dynamic loads is reduced. In some important occasions, we can take some anti-loosening measures to ensure the reliability of nut locking, chinese patent discloses a high-performance locking nut (issued publication No. CN 213744419U) for automobiles, the technology of the patent is provided with a second spiral surface on the upper end surface of a gasket and a first spiral surface on the lower end surface of the nut, and the spiral surface anastomosis structure between the nut and the gasket is utilized, so that the application of self-tightening force theory is realized, the anti-loosening effect is completely achieved by a specific lifting angle, the stability of a coupling pair is improved, the defect that the stress is concentrated on the traditional fasteners on the first tooth and the second tooth after the nut is screwed is avoided, the stress is uniformly distributed, the bearing capacity of the nut and the bolt is greatly improved, the damage degree of internal and external threads is also reduced, and the high-performance locking nut for automobiles is well prevented from loosening.

However, in order to make the gasket conveniently sleeved in the bolt, the diameter of the through hole of the gasket is larger than that of the bolt, so that the gasket can transversely move or incline after being sleeved in the bolt, further, the position of the gasket deviates after screwing the nut, the fastening effect is poor, the gasket is thinner, when the locking bolt is not completely fastened, the gasket is extruded to deform, and at the moment, the bolt is difficult to continuously fasten, but the fastening effect does not reach an ideal value, and the fastening effect is affected. Accordingly, one skilled in the art would be able to provide a high performance lock nut for an automobile that addresses the problems set forth in the background above.

Disclosure of Invention

In order to solve the technical problems, the utility model provides a high-performance lock nut for an automobile, which comprises a bolt, a nut sleeve and a nut, wherein the nut sleeve comprises a sleeve wall and a gasket, the sleeve wall is fixedly connected with the gasket, and a nut groove is formed in the nut sleeve;

the sleeve wall inner wall is matched with the nut outer wall in size, the first latch is fixedly connected with the bottom of the gasket, and the second latch is fixedly connected with the top of the nut.

Preferably: the nut sleeve and the nut are respectively provided with a through hole, and the diameter of each through hole is larger than that of the bolt.

Preferably, a reinforcing ring is arranged in the nut groove.

Preferably, two sides of the reinforcing ring are fixedly connected with the gasket and the sleeve wall respectively.

Preferably, the first latch is matched with the second latch in shape.

The utility model has the technical effects and advantages that:

1. after the second latch of the nut is combined with the first latch of the gasket, the nut can be clamped into a nut groove of the nut sleeve, and the nut cannot move or incline transversely under the influence of the screw threads of the bolt, so that the nut sleeve is limited not to move or incline transversely, and the position deviation or incline of the gasket is finally avoided;

2. the strength of the gasket is increased by using the sleeve wall and the reinforcing ring, so that the gasket is prevented from being extruded and deformed when the nut is fastened, and the fastening degree of the nut is ensured.
