Novel automatic check nut

Abstract

The invention discloses a novel automatic check nut. The novel automatic check nut comprises a nut body and two L-shaped rotating blocks, wherein a threaded hole is formed in the nut body; the bottom of the vertical part of each L-shaped rotating block is a fillet; the inner end face of the horizontal part of each L-shaped rotating block is provided with multiple protrusions arranged in an array; the nut body is symmetrically provided with two horizontal grooves; the nut body is provided with vertical containing grooves; a first air cylinder is arranged at the bottom of each containing groove, and a telescopic rod of the first air cylinder extends upwards; a push block is arranged at the end of the telescopic rod of each first air cylinder; the vertical part of each L-shaped rotating block is contained in one containing groove; the width of each horizontal groove larger than the width of each L-shaped rotating block; the vertical part of each L-shaped rotating block can slide up and down in the corresponding containing groove; the horizontal part of each L-shaped rotating block comprises a fixed block, a connecting block and second air cylinders. The novel automatic check nut occupies a small space when not used, is convenient to carry and use, can also be used as a common nut and has multiple functions.

Description

technical field [0001] The invention relates to an automatic novel anti-loosening nut, in particular to an automatic novel 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 threaded...

Problems solved by technology

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
