[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-slip bolt structure, including a screw 1, a groove 2 at one end of the screw 1, a support rod 3 slidably connected to the inner wall of the groove 2, a limiting groove 4 inside the support rod 3, a limiting plate 5 slidably connected to the inner wall of the limiting groove 4, a support rod 6 fixedly connected to one side of the limiting plate 5, one end of the support rod 6 slidably penetrating to the outside of the support rod 3, one end of the support rod 6 fixedly connected to the inner wall of the groove 2, a rotating hole at one end of the support rod 3, a rotating rod 8 rotatably connected to the inner wall of the rotating hole, a rotating plate 9 fixedly connected to one end of the rotating rod 8, the outer surface of the rotating plate 9 rotatably connected to the inner wall of the limiting groove 4, a support plate 10 fixedly connected to the other end of the rotating rod 8, and a first spring 7 provided on the outer surface of the support rod 6;

[0020] One end of the first spring 7 is fixedly connected to one end of the support rod 3, and the other end of the first spring 7 is fixedly connected to the inner wall of the slide groove 2.

[0021] Through the above embodiments, when the bolt is fixed, the elastic potential energy provided by the first spring 7 is released by the first spring 7 to push the support plate 10. The support plate 10 cannot move because it is in contact with the inner wall of the thread groove. Then, through the reaction of the force, the screw 1 will be driven to the outside of the thread groove, thereby increasing the friction between the screw 1 and the thread groove, thus preventing the bolt from stripping. The support rod 6 can increase the structural stability of the support rod 3. At the same time, the cooperation between the rotating rod 8 and the support plate 10 ensures that the rotation efficiency of the screw 1 is not seriously affected after the support plate 10 contacts the inner wall of the thread groove, thus increasing the convenience of bolt installation.

[0022] The other end of the screw 1 is fixedly connected to a support block 11. A plurality of sliding grooves 12 are provided on one side of the support block 11, and a sliding tube 13 is slidably connected to the inner wall of the sliding groove 12.

[0023] A fixed rod 14 is slidably connected to the inner wall of the slide tube 13. One end of the fixed rod 14 is fixedly connected to the inner wall of the slide groove 12. A second spring 15 is provided on the outer surface of the fixed rod 14.

[0024] One end of the second spring 15 is fixedly connected to one end of the slide tube 13, and the other end of the second spring 15 is fixedly connected to the inner wall of the sliding groove 12.

[0025] An annular plate 16 is fixedly connected to one end of multiple sliding tubes 13. Multiple ball grooves 17 are provided on one side of the annular plate 16, and a rotating ball 18 is rotatably connected to the inner wall of the ball groove 17.

[0026] Through the above embodiments, the support block 11, sliding groove 12, sliding tube 13, fixed rod 14, second spring 15, annular plate 16, ball groove 17 and rotating ball 18 cooperate with each other. In the application of threaded holes, the support block 11 drives the annular plate 16 to contact the outer surface of the device with threaded holes. The elastic potential energy given by the second spring 15 causes the support block 11 to drive the screw 1 to have a force to pull out from the inside of the threaded hole, thereby increasing the friction between the screw 1 and the threaded hole, thus avoiding stripping. The rotating ball 18 can reduce the coefficient of friction between the annular plate 16 and the contact body, thereby reducing the influence of the annular plate 16 on the rotation of the support block 11.

[0027] Working principle:

[0028] like Figures 1-4 As shown, during use, the elastic potential energy provided by the first spring 7 allows the bolt to be fixed. When the bolt is fixed, the elastic potential energy released by the first spring 7 pushes the support plate 10. Since the support plate 10 cannot move due to contact with the inner wall of the thread groove, the reaction force causes the screw 1 to move outward from the thread groove, increasing the friction between the screw 1 and the thread groove. This prevents the bolt from stripping. The support rod 6 increases the structural stability of the support rod 3. Furthermore, the cooperation between the rotating rod 8 and the support plate 10 ensures that the contact between the support plate 10 and the inner wall of the thread groove does not significantly affect the rotation efficiency of the screw 1, thus improving the bolt installation efficiency. For ease of use, the support block 11, sliding groove 12, sliding tube 13, fixed rod 14, second spring 15, annular plate 16, ball groove 17 and rotating ball 18 work together. In the application of threaded holes, the support block 11 drives the annular plate 16 to contact the outer surface of the device with threaded holes. The elastic potential energy given by the second spring 15 causes the support block 11 to drive the screw 1 to have a force to pull out from the inside of the threaded hole, thereby increasing the friction between the screw 1 and the threaded hole, thus avoiding stripping. The rotating ball 18 can reduce the coefficient of friction between the annular plate 16 and the contact body, thereby reducing the influence of the annular plate 16 on the rotation of the support block 11.

[0029] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
