A general anti-loosening bolt and its assembly and installation method

Abstract

The invention provides a universal check bolt and an assembly and installation method thereof, and belongs to the field of bolts. According to the universal check bolt and the assembly and installation method thereof, the problem that a conventional check bolt cannot fix a normal connecting piece is solved. The universal check bolt comprises a screw rod, a bolt head and a reset spring, wherein threads are arranged on the periphery of the screw rod; a movable cavity is formed in the screw rod; a movable rod is arranged in the movable cavity; a plurality of anti-loosening holes are formed in thescrew rod; an anti-loosening sheet is adaptively arranged in each anti-loosening hole; a driven telescopic mechanism is arranged between the inner side edges of the anti-loosening sheets and the movable rod; a rubber strip is fixed on the outer side edge of each anti-loosening sheet; sawteeth are arranged on the rubber strips; a plurality of adjusting holes are formed in the bolt head; an adjusting rod is arranged in each adjusting hole; a driving telescopic mechanism is arranged between the inner ends of the adjusting rods and the movable rod; the outer end of each adjusting rod is a spherical adjusting head; the reset spring is positioned in the movable cavity; and the two ends of the reset spring abut against the top end of the movable cavity and the top end of the movable rod. By means of the universal check bolt, a traditional bolt can be directly replace, so that the universality is better; and the universal check bolt is prevented from being completely locked, later disassemblyand maintenance are facilitated, and the universal check bolt is easy and convenient to assemble and disassemble.

Description

technical field [0001] The invention belongs to the technical field of bolts, and relates to a universal anti-loosening bolt and an assembly and installation method thereof. Background technique [0002] Bolt connection is the most common connection method, which is used for fastening, but the vibration of the fastened object will cause the bolt to loosen, which will have serious consequences. The traditional method is to inject glue on the bolt, but there is a risk of preventing There are many problems such as poor loosening effect, troublesome installation, inconvenient disassembly, etc. Therefore, how to improve the anti-loosening effect and overcome the above problems has always been a subject of research. [0003] The existing application number is 201710183959.7, which is a Chinese invention patent named "An active intrusive bolt connection anti-loosening structure and its forming process". The ring groove of the first connected part is connected, and the elastic anti...

Problems solved by technology

[0002] Bolt connection is the most common connection method, which is used for fastening, but the vibration of the fastened object will cause the bolt to loosen, which will have serious consequences. The traditional method is to inject glue on the bolt, but there is a risk of preventing There are many problems such as poor loose effect, troublesome installation, inconvenient disassembly, etc. Therefore, how to improve the anti-loose effect and overcome the above problems has always been a research topic.

[0004] 1. It is necessary to change the through-hole structure of the first connected part, so the bolts of this structure can only be adapted to the connecting parts of the corresponding structure, and the conventional connecting parts cannot be universally fastened

[0005] 2. After the elastic anti-loosening ring is installed, it is not only anti-loosening, but the bolt is locked as a whole, so the bolt cannot be disassembled, so maintenance and replacement are inconvenient, and it is not suitable for occasions where bolts need to be disassembled, so the scope of application is limited

[0006] 3. In the process of connecting the bolts, the structure needs to be additionally equipped with elastic anti-loosening rings, which makes the construction more troublesome
