[0027] 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.

[0028] Referring to Figures 1 to 3, one embodiment of this utility model provides a multifunctional elastic steel pad, including a nut 1, a screw 8 fixedly connected to the top of the nut 1, a nut 7 rotatably connected to the outside of the screw 8, and a buffer assembly rotatably connected to the outside of the nut 7. This buffer assembly effectively disperses the pressure between the nut 7 and the nut 1 through elastic deformation, significantly improving the stability and reliability of the connection.

[0029] Referring to Figures 1 and 4, the buffer assembly includes a gasket 2, the bottom of which is movably connected to the top of the nut 1. A rubber pad 3 is fixedly connected to the outside of the gasket 2, and a spring 4 is fixedly connected to the outside of the rubber pad 3. When the nut 7 is tightened, the gasket 2, as a basic support structure, initially buffers the pressure through the elastic deformation of the rubber pad 3, effectively reducing the stress concentration phenomenon caused by rigid contact.

[0030] The other end of the spring 4 is fixedly connected to a rubber pad 2 5, and a washer 2 6 is fixedly connected to the outside of the rubber pad 2 5. When the spring 4 is subjected to axial pressure, it undergoes elastic compression, stores energy and provides continuous rebound force. The rubber pad 2 5 further absorbs the vibration energy released by the spring 4, forming a double buffer mechanism.

[0031] The outer surface of washer 6 contacts the outer surface of nut 7, and the inner wall of washer 6 is slidably connected to the outer surface of screw 8. This structural design ensures that washer 6 can move synchronously with the rotation of nut 7, while maintaining coaxiality with screw 8, avoiding displacement during the buffering process that would reduce the buffering effect;

[0032] Referring to Figures 1, 2, and 4, the inner wall of rubber pad 2 5 is slidably connected to the outside of screw 8, and the inner wall of spring 4 is slidably connected to the inner wall of screw 8. Through the sliding engagement with screw 8, rubber pad 2 5 and spring 4 can maintain a stable axial movement trajectory when subjected to force and deformation, preventing structural damage caused by lateral displacement and extending service life;

[0033] The inner wall of rubber pad 3 is slidably connected to the inner wall of screw 8, and the inner wall of washer 2 is slidably connected to the inner wall of screw 8. This sliding connection method makes the installation of the buffer assembly on screw 8 more compact, while ensuring that each component can work together under force, thus improving buffering efficiency;

[0034] Gasket 2 is made of steel, and rubber pad 3 is made of rubber. The steel gasket 2 provides high-strength basic support and can withstand greater pressure without deformation; the rubber pad 3 utilizes its high elasticity and damping properties to effectively absorb and disperse vibration energy, further enhancing the cushioning effect.

[0035] Working principle: During installation, first, the first washer (2) is put into the screw (8), with its bottom fitting against the top of the nut (1). The first rubber washer (3) is attached to the outside of the first washer (2). The high elasticity of the rubber initially absorbs the pressure generated when the nut (7) is tightened, reducing the impact of rigid contact. One end of the spring (4) is connected to the first rubber washer (3), and the other end is fixed to the second rubber washer (5) and the second washer (6). During the rotation of the nut (7), the spring (4) is compressed and undergoes elastic deformation, storing energy and continuously buffering the axial pressure of the nut (7) on the nut (1). The second rubber washer (5) works with the spring (4) and uses its own damping characteristics to convert the rebound energy of the spring 4 into heat energy consumption, further weakening the vibration transmission. The second washer (6) is in close contact with the nut (7) and moves synchronously, ensuring that the buffer assembly runs stably on the screw (8). Through the rigid support of the steel washer and the elastic buffering of the rubber and spring 4, vibration reduction and loosening of the connection part are achieved, ensuring the long-term stable operation of the mechanical structure.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
