The loosening prevention nut connecting structure is simple in structure and good in loosening prevention performance.

Description

technical field [0001] The invention relates to a fastener connection structure, in particular to an anti-loosening nut connection structure. Background technique [0002] Generally, mechanical machines have vibrations when they work, which not only consumes part of the power and wastes energy, but also causes loosening of various connecting parts, especially in the parts where nuts and bolts are connected. Once the nuts are loose, they may fall off. , resulting in accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-loosening nut connection structure, which has a simple structure and good anti-loosening performance. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solution: an anti-loosening nut connection structure, including a connecting piece and a screw passing through the connecting piece, and a nut is screwed on the screw...
