Bolt assembly with locking function

Abstract

The invention relates to a bolt assembly with a locking function. The bolt assembly comprises a bolt, a fixing nut and a gasket, wherein the bolt comprises a bolt head and a bolt shaft formed by extending perpendicularly relative to the bolt head, and the peripheral surface of the bolt shaft is provided with a first thread; a second thread combined with the first thread is formed in the fixing nut; the gasket is arranged between the bolt and a fastened object; the lower end face of the bolt head is provided with a plurality of combination protrusions; each combination protrusion comprises an inclined surface and a vertical surface, wherein the high end and the lower end of the inclined surface face the loosening direction and the fastening direction of the bolt correspondingly. The upper surface of the gasket is provided with a plurality of clamping protrusions. Each clamping protrusion comprises a clamping inclined surface and a vertical surface, wherein the high end and the lower endof the clamping inclined surface face the loosening direction and the fastening direction of the bolt correspondingly. A magnetic component for keeping the gasket and the fastened object in a restrained state through magnetic force is arranged in the gasket. In this way, when rotating force in the loosening direction is applied to the bolt, the inclined surfaces of the bolt can be clamped by theclamping inclined surfaces of the gasket so as to prevent rotating.

Description

technical field [0001] The invention relates to a bolt assembly with an anti-loosening function, more specifically, an anti-loosening bolt assembly capable of providing a stable anti-loosening effect for a long time. Background technique [0002] Bolts and nuts have been widely used in various fields since long ago as fasteners that maintain fastening force by screwing together. However, bolts and nuts maintain fastening force through friction between the internal thread and external thread, so there is a disadvantage that they are easy to loosen when subjected to shock and vibration. [0003] Therefore, various structures for preventing loosening of bolts and nuts after tightening are being studied. As one example, Korean Granted Patent Publication No. 10-1999-0019896 discloses a loosening prevention structure of bolts and channel nuts. The disclosed structure includes a channel nut in which a plurality of fixing grooves are radially formed, and a plurality of bolts protr...

AI Technical Summary

Problems solved by technology

Because of this structure, it is difficult to process the fixing frame formed by the extension of the bolt end, and the fixing frame needs to be bent one by one after tightening, so there is a problem of prolonging the man-hour and working time

[0004] In addition, various anti-loosening bolts have also appeared, but due to their complex structure, they are inconvenient to manufacture and use, and there is a shortcoming that the anti-loosening effect gradually decreases with the passage of time.
