Technical Field

[0001] The utility model relates to the technical field of air spring vibration isolators, in particular to an air spring vibration isolator with adjustable shock absorption hardness. Background Technique

[0002] The air spring shock absorber is a relatively new technology. Although its application is not yet widespread, it is a very promising vibration isolation solution. It has been increasingly valued by people and has been adopted in some engineering vibration isolations. An air spring is a rubber bladder reinforced by cord, filled with compressed air, and is a vibration damping rubber product that uses the compressibility of gas to act as a spring. There are types such as long pillow type, gourd type, and diaphragm type.

[0003] When the existing air spring vibration isolator is fixed to an object, it is generally directly fixed at a certain place of the device. After long-term use, the air spring vibration isolator is prone to damage but difficult to disassemble for replacement or repair; therefore, we propose an air spring vibration isolator with adjustable shock absorption hardness to solve this problem.
