Novel automatic lock bolt

Abstract

The invention discloses a novel automatic lock bolt. An accommodating slot is formed in a screw rod; the accommodating slot is communicated with a horizontal through slot; a first cylinder is arranged at the bottom of the accommodating slot; the first cylinder is provided with a stretching rod which upward extends out; a pushing block is arranged on an end part of the stretching rod of the first cylinder; a switch is arranged on an upper surface of a bolt head; I-shaped parts of two L-shaped rotating blocks are abutted to each other and are accommodated in the accommodating slot; a gap is remained between a lower end part of a bulge and the bottom of the horizontal through slot; the I-shaped parts of two L-shaped rotating blocks can slide up and down in the accommodating slot; when the I-shaped parts of two L-shaped rotating blocks upward slide to the top positions, the I-shaped parts can be downward turned; a '-' part of each L-shaped rotating block comprises a fixing block, a connecting block and a second cylinder; a second switch is arranged on the upper surface of the bolt head. The novel automatic lock bolt provided by the invention can avoid the abrasion or damage to the bulge; the stretching forces of the cylindesr can ensure the contact force and frictional force between the bulge and the two lateral surfaces; the occupied space is small; the novel automatic lock bolt is conveniently taken and used.

Description

technical field [0001] The invention relates to an automatic novel anti-loosening bolt, in particular to a novel anti-loosening bolt used on plates, and belongs to the technical field of mechanical fasteners. Background technique [0002] Bolts are a type of fastener consisting of a bolt head and a screw rod (a cylinder with external threads), which are used to fasten two mechanical parts with through holes. If the bolt is unscrewed, the two parts can be separated, so the bolt connection is a detachable connection and is widely used on the plate. When the mechanical equipment is running, mechanical vibration will inevitably occur. Long-term mechanical vibration will cause the bolts to shake, resulting in thread wear, making the fastening effect of the bolts worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision parts. The machining accuracy of the equipment may also cause bolts to escape from the threaded hole...

Problems solved by technology

However, when the bolt is in a normal state, the upper surface of the "I" part of the "L" shaped turn block is higher than the upper surface of the bolt head, which takes up a large space and is extremely inconvenient to carry and use; and when in use, the "L" When the turning block is turned over, before the inner end surface of the "--" part of the "L"-shaped turning block comes into contact with the surfaces on both sides of the plate, the plate will squeeze several protrusions on the outside, causing the protrusions to be worn or damaged, which seriously affects the anti-loosening of the bolts Effect
