Under the action of the damping spring 6, the air bag damper 3 and the lower mounting plate 2, the air spring isolator body is formed, so that the damper can continue the corresponding vibration reduction work. An adjusting rod 5 is also provided inside the damping spring 6, and an adjusting nut 7 is provided below the adjusting rod 5 and below the lower mounting plate 2 through a threaded connection. Under the action of the adjusting nut 7, the distance between the upper mounting plate 1 and the lower mounting plate 2 can be adjusted, and then the stiffness of the air spring isolator can be adjusted, so that the device can better meet the needs of actual use.

[0023] A mounting bracket 4 is also provided on the top of the upper mounting plate 1. Under the action of the mounting bracket 4, the device can be connected to the equipment that needs vibration reduction, thereby ensuring the installation quality of the air spring vibration isolator. A base 9 is provided at the bottom of the lower mounting plate 2 through a fixing block 8. A bottom plate 10 is provided at the bottom of the base 9. Under the action of the bottom plate 10, the air spring vibration isolator can be installed in a suitable position for use, thereby ensuring the efficiency of the use of the air spring vibration isolator. A number of support plates 11 are also evenly provided on the top of the bottom plate 10. A through hole is provided on the support plate 11. A slide rod 12 is provided in the through hole through a sliding connection. The slide rod 12 is provided with The moving block 14 and the side wall of the base 9 are evenly provided with a number of card slots for use with the moving block 14. Under the action of the card slots and the moving block 14, the base 9 can be installed and fixed, thereby ensuring the installation quality of the air spring vibration isolator. A first return spring 13 is also sleeved on the outside of the slide rod 12. One end of the first return spring 13 is connected to the support plate 11, and the other end of the first return spring 13 is connected to the moving block 14. At this time, under the action of the first return spring 13, the connection quality of the moving block 14 and the card slot is guaranteed, thereby ensuring the installation work of the air spring vibration isolator, thereby ensuring the use efficiency of the air spring vibration isolator.

[0024] The bottom plate 10 is also evenly provided with a plurality of cavities, in which a slide plate 15 is slidably provided, and a plug rod 16 is provided on the top of the slide plate 15. A socket for cooperating with the plug rod 16 is provided on the moving block 14. Under the action of the plug rod 16, the moving block 14 can be fixed, thereby further ensuring the connection quality of the moving block 14 and the base 9, thereby better installing the air spring vibration isolator. A telescopic rod 17 is also provided in the cavity, and the end of the telescopic arm at the top of the telescopic rod 17 is connected to the slide plate 15. Under the action of the telescopic rod 17, the slide plate 15 can be driven to move up and down. A second return spring 18 is also sleeved on the outside of the telescopic rod 17. One end of the second return spring 18 is connected to the slide plate 15, and the other end of the second return spring 18 is connected to the inner wall of the cavity. At this time, under the action of the second return spring 18, the restriction of the plug rod 16 on the moving block 14 is guaranteed. A handle 19 is provided on the slide plate 15, and the slide plate 15 can be moved under the action of the handle 19.

[0025] Once the equipment requiring vibration reduction is connected to mounting bracket 4, the entire air spring isolator begins to function. The damping spring 6 and airbag damper 3 together form the isolator's primary damping elements. When the equipment is subjected to vibration, the damping spring 6 begins to deform to absorb and reduce vibration energy, while the airbag damper 3 dissipates vibration energy through internal air flow, further reducing vibration transmission. To adjust the stiffness of the air spring isolator, rotate the adjustment nut 7 to adjust the distance between the upper mounting plate 1 and the lower mounting plate 2, thereby varying the distance between them. This change in distance will directly affect the compression degree of the vibration-damping spring 6, and thus change the stiffness of the vibration isolator. When the stiffness needs to be increased, the distance between the upper mounting plate 1 and the lower mounting plate 2 can be reduced to put the vibration-damping spring 6 in a tighter compression state; conversely, when the stiffness needs to be reduced, the distance between the two can be increased to reduce the compression degree of the vibration-damping spring 6. When the air spring vibration isolator needs to be disassembled, the staff drives the slide plate 15 to move through the handle 19, so that the insertion rod 16 releases the restriction on the moving block 14. At this time, moving the moving block 14 outward can release the restriction on the base 9, thereby removing the air spring vibration isolator and then performing maintenance on the air spring vibration isolator, thereby ensuring the use efficiency of the air spring vibration isolator.
