Locknut structure and using method thereof

Abstract

The invention provides a locknut structure and a using method thereof, and belongs to the field of mechanical accessories. The lock nut structure solves the problems that an existing lock nut is poorin universality, troublesome in operation and poor in mistake proofing performance. The locknut structure comprises a hexagon nut provided with a threaded hole, an anti-loosening groove is formed in the outer wall of the top end of the nut, an anti-loosening sleeve is sleeved with the anti-loosening groove, the outer wall of the anti-loosening sleeve is of a regular hexagon sleeve-shaped structurecoaxial with the threaded hole, an outer clamping groove and an inner clamping groove are formed in the groove wall of the anti-loosening groove and the inner wall of the anti-loosening sleeve and rotationally connected through clamping rings, and an anti-loosening plate is fixed to the inner wall of the top end of the anti-loosening sleeve; and an extrusion groove is coaxially formed in the inner wall of the top end of the nut, an extrusion part is arranged between the anti-loosening plate and the top end of the nut and comprises an extrusion sleeve and an extrusion plate, the extrusion sleeve is embedded in the extrusion groove in a matched mode, the outer edge of the extrusion plate is in threaded connection with the inner wall of the anti-loosening sleeve, an annular rubber anti-skidring is coaxially arranged in the extrusion groove, and the anti-skid ring is pressed between the extrusion sleeve and the bottom of the extrusion groove. The nut structure is good in universality, convenient to operate and good in mistake proofing performance.

Description

technical field [0001] The invention belongs to the technical field of mechanical accessories, and relates to an anti-loosening nut structure and a use method thereof. Background technique [0002] Bolt and nut screw connection is a common fastening structure, which is widely used in the field of mechanical equipment. However, the vibration of the equipment will cause the nut to loosen on the bolt, which in turn causes the nut to fall off, which is prone to safety accidents. Therefore, this fastening structure exists. It has the defect of easy loosening. [0003] The existing application number is 201910609425.5, and the Chinese invention patent application titled "A limit fastener and its assembly and use method", which sets a limit groove on the rod wall of the screw, installs an adjustment sleeve on the nut, and adjusts the sleeve. There is a rotating mechanism between the nut and the nut, and the adjustment sleeve is provided with a limit block that cooperates with the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The nut of this structure can only be used in conjunction with the bolt of this structure to form a limit fastener. The nut cannot be used in conjunction with the bolt of the traditional structure, and its versatility is poor;

[0005] 2. When rotating the nut, it is necessary to align the wrench with the nut and operate it. When rotating the adjustment sleeve, it is necessary to align the wrench with the adjustment sleeve and operate, which is troublesome to operate;

[0006] 3. The outer wall of the adjustment sleeve is the same shape as the outer wall of the nut, and the same wrench is used, which is very easy to operate incorrectly, so the error proofing is poor
