An automatic elastic anti-loosening nut

Abstract

The invention discloses an automatic elastic lock nut which comprises a nut main body and two L-shaped rotating blocks, wherein a threaded hole is formed in the nut main body; the bottoms of I-shaped parts of the L-shaped rotating blocks are arranged as circular corners; a plurality of bulges are arrayed on inner end faces of '-' shaped parts of the L-shaped rotating blocks; two horizontal slots are symmetrically formed in the nut main body; vertical accommodating slots are formed in the nut main body; a cylinder with an upward extending stretching rod is arranged at the bottom of each accommodating slot; a pushing block is arranged on an end part of the stretching rod of each cylinder; the I-shaped part of each L-shaped rotating block is accommodated in one accommodating slot; the width of the horizontal slots is greater than the width of the L-shaped rotating blocks; the I-shaped parts of the L-shaped rotating blocks can slide up and down in the accommodating slots; each of the '-' shaped parts of the L-shaped rotating blocks comprises a fixing block, a connecting block and an elastic part. When the automatic elastic lock nut provided by the invention is not used, the occupied space is small; the automatic elastic lock nut is conveniently taken and used; the automatic elastic lock nut can be used as a general nut and is multifunctional.

Description

technical field [0001] The invention relates to an automatic elastic anti-loosening nut, in particular to an automatic elastic anti-loosening nut used on plates, and belongs to the technical field of mechanical fasteners. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is used to fasten and connect two mechanical parts with through holes. If the bolt is unscrewed from the nut, the two parts can be separated, so the connection is a detachable connection, and can also be widely used on plates. When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the thre...

When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the threaded hole of the nut, which may cause mechanical failure
