The swivel seat 407 at the other end of the two connecting rods 406 is symmetrically installed on the upper and lower fixed plates 401. When the two fixed plates 401 are close to each other, the reverse thrust plate 405 is pushed toward the air column 404 through the connecting rod 406. After the air column 404 is squeezed, it expands laterally, generating a reaction force on the reverse thrust plate 405, reducing the degree of compression deformation of the rubber pad body 1, and then In order to reduce the elastic deformation of the shock-absorbing spring 402, the vibration of the shock-absorbing spring 402 is reduced, and the shock-absorbing effect is improved. An inner groove 409 is opened inside the reverse thrust plate 405, and a first piston 410 is movably installed inside the inner groove 409. The outer wall of the first piston 410 is in close contact with the inner wall of the inner groove 409. A push rod 411 is installed on the side of the two first pistons 410 that are away from each other. The end of the push rod 411 passes through the outer side of the reverse thrust plate 405.

[0028] Working principle: When the top of the rubber pad body 1 is under pressure, the rubber pad body 1 and the end rubber sheet 2 buffer the pressure to protect the equipment, and at the same time, the shock absorbing spring 402 and the air column 404 between the two fixing plates 401 are compressed, thereby further improving the buffering effect;

[0029] During the buffering process, the two fixed plates 401 approach each other, so that the connecting rod 406 rotates to push the reverse thrust plate 405 to move toward the gas column 404, and the gas column 404 expands laterally after being squeezed, thereby generating a reaction force on the reverse thrust plate 405, thereby reducing the degree of compression deformation of the rubber pad body 1, and then reducing the elastic deformation of the shock-absorbing spring 402, reducing the vibration of the shock-absorbing spring 402, and improving the shock-absorbing effect;

[0030] When the reverse thrust plate 405 moves toward the gas column 404, after one end of the push rod 414 contacts the gas column 404, the second piston 413 moves toward the inner groove 409. Under the action of gas pressure, the two first pistons 410 move away from each other, so that the push rod 411 is output outward until it contacts the fixed plate 401, thereby supporting the rubber pad body 1, further reducing the degree of compression deformation of the rubber pad body 1, and then reducing the elastic deformation of the shock-absorbing spring 402, reducing the vibration of the shock-absorbing spring 402, and improving the shock-absorbing effect.
