The invention provides a lock bolt convenient to disassemble. The lock bolt convenient to disassemble comprises a nut, a stud, threads, a hexagonal groove, a cross-shaped groove and an elastic washer, wherein the stud is cylindrical; the threads are arranged on the outer side of the lower end of the stud; the nut is arranged on the top of the stud and is in the shape of a hexagonal prism; the hexagonal groove is formed in the upper end surface of the nut; the cross-shaped groove is formed below the hexagonal groove; the elastic washer is arranged on the lower end surface of the nut; and a plurality of inner holes are formed in the elastic washer and are uniformly distributed circumferentially around the stud. By the lock bolt convenient to disassemble, the probability of incapability of disassembling due to the fact that a matched operating tool cannot be found out is greatly reduced, meanwhile, a friction force between the bolt and the surface of a connecting piece is increased, loosening of the bolt due to vibration is avoided, and bolt connecting stability is guaranteed.
Description
【Technical field】 [0001] The invention relates to the technical field of connection and fastening of parts of open-air machinery, mining machinery and chemical equipment, in particular to the technical field of a convenient disassembly and assembly anti-loosening bolt. 【Background technique】 [0002] Bolt heads are usually set in a hexagonal, quadrangular or octagonal shape. When disassembling the above-mentioned bolts, they cannot be disassembled due to the limitation of tools. The assembly tools of hexagonal sockets, square sockets or octagonal sockets take up a lot of space. Big, people need bolts to have fast and efficient performance and function in use. People have made beneficial improvements in bolt products such as cross bolts, hexagon socket bolts, etc., and other medium-sized mechanical equipment such as storm trucks and coal unloaders. Exposure to rain and sun can easily cause rust and corrosion on the exposed bolts on the equipment, the main beam, flange connect...
