[0019] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 5The utility model provides a technical solution: an anode plate step bolt structure, comprising a bolt 1, a fixing hole 2 is provided in the middle of the bolt 1, a plurality of elastic components are arranged on the rear side of the bolt 1, a fixing plate 5 is arranged on the rear side of the plurality of elastic components, a backing plate 6 is arranged on the rear side of the fixing plate 5, a fixing hole 2 is provided in the middle of the bolt 1, a thread 3 is provided in the inner cavity of the fixing hole 2, a through hole 7 is provided in the middle of the fixing plate 5 and the backing plate 6, through the setting of the elastic component, after the bolt 1 is screwed on the screw rod, the elastic component can be squeezed by the fixing plate 5, so that the elastic component applies a reaction force to the bolt 1, The pressure between the thread 3 inside the fixing hole 2 and the thread 3 on the screw rod increases, thereby increasing the friction between the two, preventing the bolt 1 from loosening after being screwed on the screw rod, and solving the problem that the bolt 1 in the prior art may rotate due to factors such as vibration during actual use, thereby becoming loose, affecting its fixing effect, and having limited stability during use. By setting the pad 6, the pad 6 made of rubber sheet will also generate corresponding elastic force when squeezed, thereby further improving the friction between the inner cavity thread 3 of the fixing hole 2 on the bolt 1 and the outer wall thread 3 of the screw rod.

[0021] In this embodiment, the elastic component includes a telescopic component and a spring 12. The telescopic component is arranged between the bolt 1 and the fixing plate 5. The spring 12 is sleeved on the outside of the telescopic component. The front and rear ends of the spring 12 are respectively fixedly connected to the bolt 1 and the fixing plate 5. Under the action of the through hole 7 and the fixing hole 2, the bolt 1, the fixing plate 5 and the pad 6 are sleeved on the outer wall of the screw, and under the action of the thread 3, the bolt 1 is screwed on the outer wall of the screw. After the pad 6 contacts the fixed object, the bolt 1 continues to rotate, so that the bolt 1 moves along the limit of the telescopic rod 9 and the telescopic cylinder 8. The spring 12 is squeezed in a straight line, so that the spring 12 produces corresponding elastic deformation, and then produces corresponding elastic force. Under the action of the elastic force of the spring 12, the bolt 1 is subjected to a reaction force, so that the pressure between the thread 3 inside the fixing hole 2 and the thread 3 on the screw rod becomes larger, thereby increasing the friction between the two, preventing the bolt 1 from loosening after being screwed on the screw rod, and solving the problem that the bolt 1 in the prior art may rotate due to factors such as vibration during actual use, and then become loose, affecting its fixing effect and having limited stability during use.

[0022] In this embodiment, the telescopic assembly includes a telescopic tube 8, a telescopic rod 9 and a limit assembly. The telescopic tube 8 is arranged at the front end of the fixed plate 5. One end of the telescopic rod 9 can be slidably inserted into the inner cavity of the telescopic tube 8. The other end of the telescopic rod 9 is fixedly connected to the bolt 1. The two limit assemblies are both arranged on the inner wall of the telescopic tube 8 and are respectively fixedly connected to the two sides of the outer wall of the telescopic rod 9. Under the joint action of the telescopic rod 9 and the telescopic tube 8, the bolt 1 and the fixed plate 5 can only slide relative to each other along a straight line, avoiding the fixing plate 5 from shaking due to the excessive softness of the spring 12 and being inconvenient to be sleeved on the bolt 1 and the outer wall of the screw.

[0023] In this embodiment, the limit assembly includes a limit groove 10 and a limit block 11. The limit groove 10 is opened on the inner wall of the telescopic cylinder 8. The limit block 11 can be slidably embedded in the inner cavity of the limit groove 10 and fixedly connected to the outer wall of the telescopic rod 9. Under the interaction between the limit groove 10 and the limit block 11, one end of the telescopic rod 9 can always remain inserted in the inner cavity of the telescopic cylinder 8, thereby improving the stability of the telescopic assembly during use.

[0024] In this embodiment, the inner cavity of the limiting groove 10 is matched with the outer wall of the limiting block 11 and both are dovetail-shaped, so that one end of the limiting block 11 can always remain embedded in the inner cavity of the limiting groove 10, thereby improving the stability of the limiting assembly during use.

[0025] In this embodiment, the pad 6 is a rubber plate, which will generate corresponding elastic force after being squeezed to increase the friction between the inner cavity thread 3 of the fixing hole 2 on the bolt 1 and the outer wall thread 3 of the screw.

[0026] The use method and advantages of the utility model: When in use, the working process is as follows:

[0027] When in use, the bolt 1, the fixing plate 5 and the backing plate 6 are sleeved on the outer wall of the screw rod under the action of the through hole 7 and the fixing hole 2, and the bolt 1 is screwed on the outer wall of the screw rod under the action of the thread 3. After the backing plate 6 is in contact with the fixed object, the bolt 1 is continuously rotated, so that the bolt 1 squeezes the spring 12 along a straight line under the limiting action of the telescopic rod 9 and the telescopic cylinder 8, so that the spring 12 generates corresponding elastic deformation, and then generates corresponding elastic force. Under the elastic force of the spring 12, the bolt 1 is subjected to a reaction force, so that the thread 3 inside the fixing hole 2 and the screw rod are in contact with each other. The pressure between the threads 3 on the upper surface increases, thereby increasing the friction between the two, preventing the bolt 1 from loosening after being screwed on the screw rod, and solving the problem that the bolt 1 in the prior art may rotate due to factors such as vibration during actual use, thereby causing loosening, affecting its fixing effect, and having limited stability during use. By setting the pad 6, the pad 6 made of rubber sheet will also generate corresponding elastic force when squeezed, thereby further improving the friction between the inner cavity thread 3 of the fixing hole 2 on the bolt 1 and the outer wall thread 3 of the screw rod.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
