A self-locking fastening bolt

Abstract

The invention belongs to the technical field of bolts, in particular to a self-locking fastening bolt. The existing self-locking fastening bolts are inconvenient to disassemble and need to cooperate on both sides for disassembly, especially when the position away from the nut is difficult to disassemble. When it is used for human control, it is more difficult to disassemble, and even the fixed object needs to be destroyed to remove the bolt, resulting in the technical problem of incomplete disassembly of the object. The side end of the self-locking screw rod away from the nut is provided with a self-locking groove, and a self-locking component is arranged in the self-locking groove. The self-locking component includes a self-locking spring and a self-locking block. The lock spring is fixedly connected to the inner wall of the self-locking groove, and the inner side of the self-locking groove is also provided with an unlocking component. The invention has the advantages of convenient and quick installation, sensitive self-locking, good stability, and convenient disassembly. When disassembling, it is not necessary to cooperate on both sides for disassembly, and the bolt can be removed smoothly to ensure the complete disassembly of the object.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a self-locking fastening bolt. Background technique [0002] Bolts are fasteners that are often used to fasten two or more parts or components into a whole. When bolting two parts or components, it is first necessary to pass the bolt through the mounting hole from one side of the part to be connected, so that the nut rests on the part to be connected and keep the bolt still, and use the other side of the part to be connected. The bolt and nut are fastened to the threaded rod. When the area of ​​the part 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 part to be connected, which makes the installation process cumbersome, labor-intensive and time-consuming. [0003] The Chinese utility model patent with the authorization announcement number CN207470555U discloses a "self-loc...

AI Technical Summary

Problems solved by technology

[0005] Based on the inconvenient disassembly of the existing self-locking fastening bolts, both sides need to cooperate to disassemble, especially when the position away from the nut is difficult to be manipulated by humans, disassembly is more difficult, and even the fixed objects need to be destroyed. To remove the bolt, resulting in the technical problem of incomplete disassembly of the object, the present invention proposes a self-locking fastening bolt
