Problems solved by technology

[0003] 1. The processing is troublesome, and the auxiliary nut needs to be specially made. First, the original nut on the bottom frame leg must be disassembled, and a concave conical surface corresponding to the main nut must be processed, and then reinstalled;
[0004] 2. There are limitations to the chassis feet of small equipment. Small bolts and nuts are generally used for the chassis feet of small equipment. If you encounter this structure, it will undoubtedly increase the difficulty of processing, or even fail to process it, because the small nuts The size itself is small. If a concave cone is processed again, the wall thickness will not meet the requirements, and it will be easily damaged by strong stress and cause damage.

Abstract

The invention discloses a universal nut locking assembly, and relates to the technical field of fasteners. The universal nut locking assembly comprises a mounting bolt and a mounting nut, wherein themounting bolt is provided with an upper nut and a lower nut above the mounting nut, and the lower nut fits and wraps the outer peripheral surface of the mounting nut; one of the upper nut and the lower nut is provided with a protruding part of which the outer peripheral edge is gradually narrowed along the circumferential direction of the inner hole of the nut, and the other nut is provided with asunken part of which the inner peripheral edge is gradually narrowed along the circumferential direction of the inner hole of the nut; the protruding part and the sunken part are mutually matched, and the sunken part and the inner hole of the nut are eccentrically arranged; the protruding part and the inner hole of the nut are concentrically arranged. The universal nut locking assembly disclosedby the invention has the advantages of good locking effect, convenient processing and good practicability.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a general anti-loosening nut assembly. Background technique [0002] According to the patent disclosed by the announcement number CN206478100U on September 08, 2017, it includes a main nut and an auxiliary nut. The top of the main nut is provided with a slightly eccentric convex tapered surface, and the bottom of the auxiliary nut is provided with a concave tapered surface. , the two cooperate with each other, and this strong stress will be applied in the opposite direction to the bolts engaged with the threaded holes. This structure has the following problems: [0003] 1. The processing is troublesome, and the auxiliary nut needs to be specially made. First, the original nut on the bottom frame leg must be disassembled, and a concave conical surface corresponding to the main nut must be processed, and then reinstalled; [0004] 2. There are limitations to the chassis feet of ...
