Lock bolt

Abstract

The invention discloses a lock bolt. The lock bolt comprises a bolt head and screw rod, wherein the bolt head and the screw rod are connected into a whole, and a through groove is formed in the upper surface of the bolt head; two L-shaped rotating blocks are symmetrically arranged in the through groove; the top ends of I-shaped parts of the L-shaped rotating blocks are rotatably connected with a side plate of the through groove; when the I-shaped parts of the L-shaped rotating blocks are located in the through groove, transverse-line-shaped parts of the L-shaped rotating blocks face the screw rod; the thicknesses of the L-shaped rotating blocks are equal to the width of the through groove; and a plurality of bosses are arrayed on the inner end faces of the transverse-line-shaped parts of the L-shaped rotating blocks. The lock bolt provided by the invention uneasily gets loose when a mechanical device works and generate mechanical vibration, so that the thread is uneasily abraded, the fastening effect is improved, the working performance and the stability of the mechanical device are improved, specifically the machining precisions of a plurality of precision devices are guaranteed, and phenomenon that the bolt is separated from a threaded hole is further prevented.

Description

technical field [0001] The invention relates to an anti-loosening bolt, in particular to an anti-loosening bolt used for connecting a workbench and a side plate. 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, which is widely used to connect the workbench and the side 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 holes, which may ...
