A round table 10 is fixedly arranged in the middle of the top of the circular plate 6, and a binding ring 11 is fixedly arranged on the top of the round table 10. The mounting belt 8 passes through the through hole 9, and these mounting belts 8 are tied to the binding ring 11 together, so that the piston assembly and the shock-absorbing washer 4 can be installed together, and can also be disassembled later, so that the shock-absorbing washer 4 is easy to replace when it is damaged.

[0026] See also Figure 1-3A through-tube 12 is fixedly provided at the bottom end of the shock-absorbing shell 1, and rolling grooves 13 are evenly arranged on the inner side of the through-tube 12. Balls 14 are slidably arranged in the rolling grooves 13. The piston rod 2 passes through the through-tube 12, and the through-tube 12 contacts the balls 14. Three-quarters of the volume of the balls 14 is located in the rolling grooves 13. When the piston rod 2 moves in the rolling grooves 13, the balls 14 effectively guide the telescopic movement of the piston rod 2 relative to the shock-absorbing shell 1, thereby reducing the positional deviation of the shock-absorbing shell 1 when it enters the interior of the shock-absorbing shell 1 due to severe vibration.

[0027] See also Figure 1 The outer side of the shock-absorbing washer 4 is provided with a second mounting belt 15, and the bottom end of the shock-absorbing washer 4 is provided with a third mounting belt 16.

After installation, its positioning column 19 is inserted into the corresponding positioning cylinder 20, and the positioning column 19 contacts the shock-absorbing airbag 21. When the piston assembly is in the process of rising, the shock-absorbing airbag 21 will squeeze the positioning column 19, thereby reducing the shock absorption of the piston assembly when the piston assembly is rising.

[0029] During specific operation, the equipment that requires shock absorption is installed on the top of the shock-absorbing shell 1 of the present application, and the mounting plate 5 can be installed on the ground. The upper end of the shock-absorbing shell 1 is also provided with an air valve port 3 to allow compressed air to enter. The piston rod 2 at the bottom end of the piston assembly can pass through the bottom of the shock-absorbing shell 1. When subjected to vibration impact, the piston assembly and the piston rod 2 are in a working state, and move up and down relative to the shock-absorbing shell 1 inside. Since the compressed air is introduced from the upper end of the shock-absorbing shell 1, the compressed air is located in the compressed air space. When subjected to vibration impact, the piston rod 2 is buffered by the compressed air during its upward movement, thereby weakening the shock-absorbing effect of the installed equipment.
