Problems solved by technology

After the conventional bolts and nuts are tightened and matched, the anti-loosening effect is not good. When used in vibration situations, the fastening reliability cannot be guaranteed; and the general nuts often need to be screwed into a long thread on the screw rod to reach the fastened position. distance, reduce work efficiency

Abstract

The invention discloses a check bolt assembly with high efficiency. The check bolt assembly comprises a bolt body, a cushion block, an anti-rotation groove, an anti-rotation body, an upper half nut, alower half nut, a fixing sleeve and a connecting assembly. A screw rod of the bolt body is sleeved with the cushion block and provided with the anti-rotation groove with an open rear end, the anti-rotation body matched with the anti-rotation groove is arranged on the inner wall of the cushion block, the upper half nut and the lower half nut are matched together to form a nut body matched with thescrew rod of the bolt body, and the cross section of the nut body is in a regular polygon shape. Compared with the prior art, the check bolt assembly has the advantages that the anti-loose effect isgood and the working efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of high-efficiency anti-loosening bolt assemblies. 【Background technique】 [0002] Fasteners are the most widely used basic parts, and are the general term for a class of mechanical parts used when two or more parts or components are fastened into a whole. There are many types and specifications of fasteners, each with different functions and uses, and the degree of standardization, serialization and generalization is extremely high. Among them, the cooperation of bolts and nuts is the most common type of fasteners. After the conventional bolts and nuts are tightened and matched, the anti-loosening effect is not good. When used in vibration situations, the fastening reliability cannot be guaranteed; and the general nuts often need to be screwed into a long thread on the screw rod to reach the fastened position. distance, reducing work efficiency. 【Cont...
