Abstract

The invention belongs to the technical field of bolts, particularly relates to a self-locking type fastening bolt, and aims to solve the technical problems that an existing self-locking type fastening bolt is inconvenient to disassemble and needs to be disassembled through two-side matching, particularly, when the position far away from one side of a nut is difficult to manually control, disassembly is more difficult, and even a fixed object needs to be damaged to take down the bolt to cause incomplete disassembly of the object. According to the technical scheme, the self-locking type fastening bolt comprises a self-locking screw and a nut which are fixedly connected, wherein a self-locking groove is formed in the side end, away from the nut, of the self-locking screw; a self-locking component is arranged in the self-locking groove; the self-locking assembly comprises a self-locking spring and a self-locking block; the self-locking block is fixedly connected to the inner wall of the self-locking groove through the self-locking spring; and an unlocking component is further arranged at the inner side of the self-locking groove. The self-locking type fastening bolt is convenient and fast to install, sensitive in self-locking, good in stability and convenient to disassemble, two sides do not need to be matched for disassembly during disassembly, the bolt can be smoothly taken down, and complete disassembly of the object is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a self-locking fastening bolt. Background technique [0002] Bolt is a fastener commonly used to fasten two or more parts or components into a whole. When connecting two parts or components with bolts, it is first necessary to pass the bolt through the mounting hole from one side of the piece to be connected, make the nut lean against the piece to be connected and keep the bolt still, and use the bolt from the other side of the piece to be connected The bolt nut is fastened on the screw rod. When the area of ​​the parts to be connected is large, one person cannot complete the operation independently, and two people are required to complete the operation on both sides of the parts to be connected respectively, which makes the installation process cumbersome, labor-intensive and time-consuming. [0003] The Chinese utility model patent whose authorization notification number is CN2...
