Problems solved by technology

However, general nuts will loosen by themselves due to some other reasons such as vibration during use, and often cause major accidents. If the maintenance is not found in time, the connection will not be firm or the bolts and nuts will fall off. Major safety accidents will occur, resulting in unsustainable estimated loss
There are many anti-loosening nuts on the market, but either the anti-loosening effect is not good, or the structure is complicated and the cost is high.

Abstract

The invention discloses a high-strength locking nut which comprises a nut body. An internal thread is arranged in a screw hole of the nut body, an annular transition portion is arranged in the axial direction of the nut body in an extending manner, and the inner diameter of the annular transition portion is slightly smaller than that of the nut body. The high-strength locking nut has the advantages of simple structure, easiness in manufacture, low cost, shock resistance, high anti-loose strength, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a high-strength lock nut, which automatically completes anti-vibration and anti-backward functions after tightening, so as to prevent the nut from being buckled and loosened due to strong mechanical shock. Background technique [0002] All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, etc.; nuts and bolts are the most commonly used fasteners. Convenient and widely used. Using nuts and bolts for connection and fastening provides convenience in disassembly and assembly for metal structure products that need to be disassembled and assembled frequently. However, general nuts will loosen by themselves due to some other reasons such as vibration during use, and often cause major accidents. If the maintenance is not found in time, the connection will not be firm or the bolts and nuts will fall off. Major safety accident...
