Variable shaft type locknut

The invention belongs to the technical field of nuts, and particularly relates to a variable shaft type locknut. According to the locknut, a bevel-edge inner nut is additionally arranged in a conventional screw nut, the rotating axes of two nuts are deflected through mutual single-edge extrusion of the two nuts, the nut shaft locking effect is achieved, and therefore the anti-loosening purpose is achieved. According to the variable shaft type locknut, the production process is simple, replacement and use are convenient, the application prospect is wide, and the locknut can be widely applied to the fields with anti-loosening requirements such as rails of high-speed rails, steel rings of automobiles and various large and small machines. 本发明属于螺母技术领域，具体涉及一种变轴型防松螺母。本发明是一种通过给常规螺丝螺母中增加一个斜边内螺母，通过两个螺母互相单边挤压来使得两个螺母的旋转轴心发生偏斜而达到螺母锁轴效果，从而达成防松目的的。本发明生产工艺简单，替换使用方便，应用前景广阔，可大范围的应用于高铁的轨道，汽车的钢圈，各种大小型机械等有防松需求在领域。
