DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The embodiment of the utility model provides a technical solution: an anti-loosening and anti-theft nut, comprising a bolt 1, a nut 2 is arranged on the bolt 1, an annular groove 3 is opened on the surface of the nut 2, main body fixing plates 4 are arranged on the front and rear sides of the inner wall of the annular groove 3, threaded holes 5 are opened on the front and rear sides of the inner wall of the annular groove 3, two threaded rods 6 are threadedly connected to the front and rear sides of the nut 2 through the two threaded holes 5, two bidirectional bearings 7 are fixed at the center of the surfaces of the opposite sides of the two main body fixing plates 4, the opposite ends of the two threaded rods 6 are connected to the bidirectional bearings 7, and the opposite sides of the two main body fixing plates 4 are provided with a plurality of elastic pressing sheets.

[0024] Effectively, the main fixed plate 4 includes a movable plate 13 and a limit rod 14, the movable plate 13 is an arc-shaped structure, the limit rod 14 is a cylindrical structure, the movable plate 13 and the limit rod 14 are a smooth transition and integrally stamped structure, the limit rod 14 is vertically installed on the outer wall of the movable plate 13, the movable plate 13 is built with an integrally stamped steel plate 8, the steel plate 8 is an arc-shaped structure, and a plurality of evenly distributed triangular cavities 16 are opened on the surface of the steel plate 8. The movable plate 13 and the limit rod 14 are both integrally stamped to improve the overall stability of each component and to prevent breakage. By building the steel plate 8 into the movable plate 13, the compressive strength of the movable plate 14 is further improved.

[0025] Furthermore, the surface of the bolt 1 is threadedly connected to the inner wall of the nut 2 , thereby facilitating the threaded connection of the nut 2 to the bolt 1 .

[0026] Furthermore, a plurality of rectangular cavities 9 are provided inside the movable plate 13, and a spring 10 is provided in the rectangular cavity 9. One end of the spring 10 is fixedly connected to a support rod 11, and the other end of the support rod 11 is connected to an elastic pressing plate 12. The elastic pressing plate 12 and the spring 10 are used in coordination to provide a buffering and protective effect on the connected parts.

[0028] Working principle: When in use, the user first passes the bolt 1 through the target connected part, and then threadedly connects the nut 2 with the other end of the bolt 1 to preliminarily fix the connected part, and then rotates the threaded rod 6 on the nut 2, and the threaded rod 6 moves in the threaded hole 5, so that the threaded rod 6 pushes the main fixing plate 4 to move. When the arc-shaped fixing plate 4 moves, it is guided by the limit hole 15 to prevent the main fixing plate 4 from moving offset, so that the two main fixing plates 4 are close to each other, and the surface of the bolt 1 is clamped by the elastic pressing plate 12, so that the nut 2 can reinforce the bolt 1 again. In addition, the coordinated use of the elastic pressing plate 12 and the spring 10 can play a buffering and protective role on the connected part.
