Fastening bolt capable of being rapidly disassembled and assembled

Abstract

The invention discloses a fastening bolt capable of being rapidly disassembled and assembled, relates to the technical field of bolts, and aims to solve the problems that in the prior art,in the usingprocess, a bolt can be independently used as a connecting piece and can also cooperate with a nut to achieve fixing, sometimes, in the process of achieving disassembling and assembling by cooperatingwith the nut, the thickness of a fixed piece is small, consequently, the rotating torque of the nut or the bolt is too long, and consequently consumed time is increased. A hexagon nut is arranged below a metal screw, a nut threaded hole is formed in the inner side of the hexagon nut, a hexagon screw cap is arranged above the metal screw, a pre-tightening gasket is arranged at the bottom of the hexagon screw cap, the pre-tightening gasket is connected with the hexagon screw cap in a welded mode, and the metal screw comprises a resistance-free rod body. A long-distance threaded groove is formedin one end of the resistance-free rod body, a short-distance threaded groove is formed in the other end of the resistance-free rod body, the metal screw rod is rotationally connected with the hexagonnut through the long-distance threaded groove, and a screw cap threaded hole is formed in the hexagon screw cap.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a fastening bolt that can be quickly disassembled. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. As nut is unscrewed from bolt, these two parts can be separated again, so bolt connection belongs to detachable connection. Bolt, be can't do without when neutralizing in the middle of industrial production manufacture at daily life, and bolt is also referred to as the rice of industry. . The utilization of visible bolt is extensively. The operation strategies of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods. Ships and ships, vehicles, hydraulic engineering, even also use bolt in chemi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fastening bolt that can be quickly disassembled to solve the problem that the bolt proposed in the above background technology can be used as a connector alone during use, or can be fixed with a nut. During the installation process, sometimes the thickness of the fixing parts is small, resulting in too long nut or bolt turning torque, which leads to the problem of increased time consumption
