Abstract

The invention discloses a spring nut with a good anti-loosening performance. The spring nut with the anti-loosening performance comprises a nut body, an inner nut and a spring washer, wherein an innernut installation chamber matched with the inner nut is arranged in the nut body; the inner nut is vertically arranged in the inner nut installation chamber and is up-and-down slidably connected withthe inner nut installation chamber; a screw-thread through hole is vertically formed in the center of the inner nut; the spring washer is arranged at the upper end of the inner nut; the upper end of the spring washer is matched with the top wall of the upper end of the inner nut installation chamber; and the spring washer downwards presses against the inner nut under a free state. According to thespring nut with the anti-loosening performance provided by the invention, the inner nut and the spring washer are arranged in the nut body, the inner nut and a bolt can be fixed in a matching way, and when the inner nut is screwed down, the spring washer at the upper end of the inner nut can be matched with the inner nut, so that anti-vibration and anti-loosening performances of the inner nut canbe improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of fasteners, especially the technical field of spring nuts. [0003] 【Background technique】 [0004] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into several types such as carbon steel, stainless steel, and non-ferrous metals according to different materials. The anti-loosening performance of the existing nuts is poor, and it needs to cooperate with spring washers to increase the anti-vibration performance of the nuts, improve the anti-loosening performance, the installation is troublesome, and additional washers are required, and the washers are easily damaged. [0005] 【Content of invention】 [0006] The purpose of the present invention is to solve the problems in the prior art, and propose a spring nut with good anti-loosening performance, which can have a spring washer inside the nu...
