Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a high-frequency and long-life compression spring. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under external force and returns to its original shape after the external force is removed. It is also called a "spring" and is generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] The springs currently used for high-frequency motion have a single structure and are difficult to adapt to high-frequency expansion and contraction, which easily causes damage. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A high-frequency and long-life compression spring comprises a shock absorbing mechanism and a high-frequency mechanism. The shock absorbing mechanism comprises a chassis, a spring body connected to the top of the chassis, and a high-frequency mechanism. The high-frequency mechanism comprises a plurality of ring bodies movably connected to the spring body, a pull rod installed inside the ring body, a rod sleeve slidably sleeved on the outside of the pull rod and connected to the top of the chassis, and a thin spring connected between the pull rod and the rod sleeve.

[0007] By adopting the above technical solution, once the spring body is compressed, the force brought by the spring body will be transmitted to multiple rings, and then the rings will transmit the force to the pull rod, and then the thin spring will be subjected to force to evenly distribute the force brought by the spring body, thereby alleviating the external force and improving the adaptability to high frequencies.

[0008] In a preferred example, the utility model can be further configured as follows: a cross section is formed at the bottom end of the spring body, and the bottom of the cross section is flush with the bottom of the chassis.

[0009] In a preferred example, the utility model can be further configured as follows: a shallow groove is opened on the top of the chassis, and the outer wall of the spring body is fixedly connected to the inner wall of the shallow groove.

[0010] In a preferred example, the utility model can be further configured as follows: a plurality of ring bodies are arranged in a ring shape at equal intervals, and the ring bodies and the pull rods are both made of metal materials.

[0011] In a preferred example, the utility model can be further configured as follows: the multiple rod sleeves have different heights and are located inside the spring body.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] In the utility model, once the spring body is compressed, the force brought by the spring body will be transmitted to multiple rings, and then the rings will transmit the force to the pull rod, and then the thin spring will be stressed to evenly distribute the force brought by the spring body, thereby alleviating the external force and improving the adaptability to high frequencies.
