[0002] In the field of mechanical vibration control technology, spring dampers are a common vibration reduction device, whose main function is to absorb and consume vibration energy through the elastic force of the spring and the flow of lubricating oil in the damper, thereby achieving effective control of vibration. In the field of external equipment design, due to the complex and changeable external environment of the equipment, the performance requirements for dampers are becoming increasingly higher. The dampers are not only required to have good vibration reduction effects, but also to be able to adapt to different working environments and working conditions.

[0003] Solutions of existing technologies: In existing spring damper designs, built-in damping structures are usually used to change the damping parameters of the product by changing the size of the damping hole. However, this design method often requires complex disassembly, processing and reassembly of the damper, which is difficult to operate, inefficient, expensive and time-consuming.

[0004] Problems with the prior art: Although the existing spring damper design has solved the problem of vibration control to a certain extent, there are still some problems and shortcomings in practical applications. First, the existing damper design often cannot meet the sealing requirements under micro-angle high-frequency vibration conditions, which can easily lead to lubricating oil leakage and affect the normal operation of the damper. Secondly, the existing damper design often cannot achieve continuous adjustment of the damping parameters, which to a certain extent limits the scope of application of the damper. Finally, the existing damper design often cannot meet the requirements of lightweight and high efficiency at the same time, which to a certain extent affects the overall performance of the equipment.
