[0002] Elastic damping buffers are important mechanical components, widely used in various situations requiring shock absorption, buffering and damping. Elastic damping buffers are devices that absorb, alleviate and disperse impact energy through elastic media and damping mechanisms. They can effectively reduce the amplitude of mechanical systems when subjected to shock or vibration, protecting equipment from damage and improving system stability and reliability.

[0003] As an important mechanical component, the elastic damping buffer is mainly used to effectively absorb and reduce the impact and vibration generated by the equipment during movement through its internal damping mechanism. This buffering effect can significantly reduce the risk of damage to the equipment caused by hard collisions, thereby protecting the structure and components of the equipment from damage.

[0004] In the existing technology, ordinary dampers cannot actively adjust the internal pressure, which may lead to problems such as poor shock absorption effect of the device in many situations, and increase the possibility of device damage. Utility Model Content
