Abstract

The invention discloses a anti-loosening bolt assembly. The bolt assembly comprises an anti-loosening bolt, an anti-loosening gasket, a fastening nut and an anti-loosening fastener, wherein the anti-loosening bolt further comprises a bolt head, a boss, a stud and an external thread, the boss is arranged at the bottom of the screw head, the stud is arranged in the center of the bottom of the boss,the external thread is arranged on the stud, the anti-loosening gasket, the fastening nut and the anti-loosening fastener are sequentially arranged on an outer side of the stud from top to bottom, a through hole corresponding to the stud in size is formed in the center of the anti-loosening gasket and the center of the fastening nut, and an internal thread is arranged on an inner wall of the fastening nut through hole. Compared with the prior art, the bolt assembly is advantaged in that the bolt assembly is simple in structure, reasonable in design, and can effectively increase friction forcebetween the fastener and the connecting piece, absorb vibration impact, guarantee long-term stability of connection and have excellent anti-loosening performance.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to an anti-loosening bolt assembly. 【Background technique】 [0002] Threaded fasteners are widely used in fastening connections between various mechanical structures, involving many industries and fields such as ships and vehicles. They are easy and convenient to disassemble, and have a good fastening effect in a short time. However, during the working process of existing threaded fasteners, due to the influence of device vibration, impact, and working condition changes, there will always be loosening and falling off, resulting in a decrease in fastening force, etc., and even lead to connection failure and falling off, resulting in huge Potential safety hazards and even personal and property losses, therefore, it is necessary to propose an anti-loosening bolt assembly. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior a...
