Description

Technical Field

[0001] The present application relates to the technical field of shock-absorbing springs, and in particular to a shock-absorbing spring that is resistant to deformation and wear. Background Art

[0002] The main function of a shock-absorbing spring is to use its unique elastic properties to absorb and disperse the energy of impact or vibration, thereby reducing the degree of structural vibration. This function helps protect structures and equipment from severe shock and vibration, thereby extending their service life and improving their working efficiency and safety. However, after a long period of use or excessive compression, the shock-absorbing spring may deform, causing it to lose its designed elastic properties. Therefore, it is necessary to improve the anti-deformation and anti-wear properties of the shock-absorbing spring.

[0003] The utility model with announcement number CN217355346U discloses a compression and deformation resistant spring, comprising a spring body and an elastic sheet, both ends of the spring body are fixedly connected with mounting seats, both ends of the mounting seat close to the spring body are provided with arc-shaped slots, the inner cavities of the four arc-shaped slots are respectively fixedly connected with the two ends of the two elastic sheets, a number of guide rods are fixedly connected with both sides of the spring body at equal distances, a buffer groove is provided between two adjacent guide rods and inside the spring body, a buffer spring is fixedly connected with the inner cavity of the buffer groove, the top of the buffer spring is fixedly connected with a guide slider, the top of the guide slider is fixedly connected with the bottom of the guide rod, the mounting seat comprises a top plate, a threaded groove, an adjusting bolt, a rotating bearing, a movable plate and a hexagonal adjusting groove. The utility model is a compression and deformation resistant spring, which enhances the compression resistance of the spring body, assists the recovery of the spring body after deformation, and adjusts the elastic force of the spring body.

[0004] When the above technical scheme is in use, the force points of the spring body are connected through the guide rod and the guide slider. When the spring body is subjected to pressure, the spring body transfers the pressure to the guide rod, and the guide rod transfers the pressure to the guide slider and the buffer spring. The buffer spring is used to enhance the elasticity of the spring body. When the spring body is subjected to uneven force and twisted, the twisting of the spring body is limited by the guide rod and the guide slider to prevent the spring body from deforming. However, the guide slider and the buffer spring provided in the above scheme are both installed inside the spring body. Therefore, it is necessary to open a plurality of buffer grooves on the spring body. The opened buffer grooves may damage the structure of the spring body, thereby affecting the use effect of the spring body and being not conducive to actual use. Therefore, a technician in this field provides a deformation-resistant and wear-resistant shock-absorbing spring to solve the problems raised in the above background technology.
