The invention discloses a self-tightening nut / bolt fastener. The self-tightening bolt fastener comprises a self-tightening nut body, a self-tightening gasket and an ordinary bolt. The contact face of the self-tightening nut body and the self-tightening gasket is a smooth transition spiral face. The self-tightening nut body is connected with the ordinary bolt in a threaded mode. The bolt fastener comprises a self-tightening bolt, a self-tightening gasket and an ordinary nut. The ordinary nut is connected with the self-tightening bolt in a threaded mode. According to the self-tightening nut / bolt fastener, by means of the self-tightening principle, a self-tightening structure is arranged on the nut / bolt, so the self-tightening effect is achieved after locking, and the nut is not moved or loosened any more; the self-tightening nut / bolt can be widely applied to machine design, machining and manufacturing industries and has revolutionary application value in railway, bridge and building industries.
Description
technical field [0001] The invention relates to the technical field of application of nut and bolt fasteners, in particular to a self-tightening nut and bolt fastener. Background technique [0002] In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts. [0003] In view of the above situation, in actual operation, people use various methods to fasten the locked nuts and bolts, such as super glue, electric welding, secondary reinforcement by perforation, etc., but there is still no way to fundamentally solve the nut The phenomenon of loose displacement. SUMMARY OF THE INVENTION [0004] The prior art is difficult to meet people's needs. In order to solve the above problem...
