Rapid anti-loosening fastening device and assembling and using method thereof

Abstract

The invention provides a rapid anti-loosening fastening device and an assembling and using method thereof, and belongs to the field of mechanical fastening devices. The rapid anti-loosening fastening device and the assembling and using method thereof solve the problem that an existing thread fastening device is low in disassembling and assembling efficiency. The rapid anti-loosening fastening device comprises a fastening bolt and a fastening nut, wherein the fastening bolt comprises a bolt rod and a bolt head, the rod wall of the bolt rod is provided with a thread groove, a one-way tooth groove is formed in the groove bottom of the thread groove, the fastening nut comprises a thread sleeve, a baffle ring is fixed on the outer wall of the bottom end of the thread sleeve, the rapid anti-loosening fastening device further comprises an inner adjusting sleeve which sleeves the outer wall of the thread sleeve and an outer adjusting sleeve which sleeves the outer wall of the inner adjusting sleeve and the outer wall of the baffle ring, an adjusting groove is formed in the inner wall of the inner adjusting sleeve, an adjusting hole is formed in the sleeve wall of the thread sleeve, the rapid anti-loosening fastening device further comprises an adjusting rod and an adjusting pipe which sleeves the adjusting rod, the adjusting pipe is arranged in the adjusting hole in a penetrating mode, the outer end of the adjusting pipe is fixedly provided with an adjusting block which is located in the adjusting groove in a sliding mode, and a baffle pipe is fixed on the hole wall of the inner end of the adjusting hole. According to the fastening device, a structure similar to the thread fit can be realized so that fixation at any degree can be realized, moreover, disassembling and assembling are efficient, and the anti-loosening effect can be realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical fastening devices, and relates to a fast anti-loosening fastening device and an assembly and use method thereof. Background technique [0002] As a commonly used fastener, the bolt cooperates with the nut to fasten the mechanical equipment. Since the bolt is connected by thread, it can be fixed to any degree, and has been widely used in various fields of production and life. [0003] The application number is 201510633255.6, and the Chinese invention patent titled "one-way rotation structure for anti-loosening mechanical fastening mechanism" has two threaded sections on the bolt body that are respectively connected to the compression nut and the anti-loosening nut. And the thread directions of the two thread segments are opposite, and it includes an adjustment ring sleeved on the bolt body and between the compression nut and the anti-loosening nut, so as to realize the one-way rotation of the c...

AI Technical Summary

Problems solved by technology

[0004] 1. Two thread segments with opposite thread directions will affect the normal tightening and loosening operation of the nut

[0005] 2. It is necessary to operate the compression nut, the anti-loosening nut and the adjustment ring separately, and the construction efficiency is low

[0006] 3. Including this patent, the fastening device through thread fit needs to be assembled and disassembled by continuously rotating the nut on the bolt, which is not suitable for equipment that requires quick assembly and disassembly
