Specific embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by accompanying drawing and implementing Example, is further elaborated to the utility model.However, it should be understood that specific embodiment described herein only to The utility model is explained, scope of the present utility model is not limited to.
Unless otherwise defined, all of technical term used herein and scientific terminology with belong to skill of the present utility model The implication that the technical staff in art field is generally understood that is identical, herein in term used in the description of the present utility model only It is to describe the purpose of specific embodiment, it is not intended that in restriction the utility model.
As shown in Figures 2 and 3, a kind of nut locking structure, including fastening bolt 3, installed in the tight of the end of fastening bolt 3 Gu nut 1, also includes being arranged on the nut anti-looseness part 2 in the outside of clamp nut 1 and for nut anti-looseness part 2 to be fixed on into fastening Locking stove bolt 4 on bolt 3;
The nut anti-looseness part 2 includes fixed plate 22, the limiting plate 21 in fixed plate 22, and the limiting plate 21 is in U-shaped, U-shaped limiting plate 21 is fixed in fixed plate 22 by two sides, and spacing hole 24, the fixed plate 22 are provided with limiting plate 21 On be provided with fixing hole 23 with the form fit of clamp nut 1;
The end of the fastening bolt 3 is provided with screwed hole, and spiral shell in first coordinated with locking stove bolt 4 is provided with screwed hole Line, the nut anti-looseness part 2 is sleeved on the outside of clamp nut 1, and clamp nut 1 is located in fixing hole 23, the locking little spiral shell Bolt 4 is fixed in the screwed hole in fastening bolt 3 through after spacing hole 24.
