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. Since the screw heads of the existing bolts cannot be replaced, if the screw heads slip again , the entire bolt needs to be scrapped, resulting in waste

Abstract

The invention discloses a straight slot flat tail screw assembly. The straight slot flat tail screw assembly comprises a screw body, a sliding groove, a cushion block, a positioning body, a nut, a fixing assembly and a screw head assembly. The screw head assembly is arranged at the front end of the screw body. The screw head assembly comprises a body integrally formed at the front end of the screwbody and a twisting head detachably connected with the body. The sliding groove with the open rear end is formed in the screw body, the screw body is sleeved with the cushion block, the positioning body cooperating with the sliding groove is arranged on the inner ring surface of the cushion block, an annular connector I is arranged on the circumferential surface of the rear end of the cushion block, and the nut located behind the cushion block is arranged on the screw body. Compared with the prior art, the anti-loosening effect can be good, waste is reduced, the anti-theft effect is achieved,and use is convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a slotted flat tail screw assembly. 【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. Since the screw heads of the existing bolts cannot be replaced, if the screw heads slip again , the whole bolt needs to be scrapped, resulting in waste. 【Content of in...
