The air spring mainly comprises a base, a diaphragm, a partition plate, a pressing ring and an air floatation top cover, wherein a cavity with an upper opening is formed in the base, the diaphragm is fixed at the opening of the base through the pressing ring to seal the opening of the cavity, the partition plate divides the sealed cavity into two parts to form a bearing air chamber on the upper layer and a damping air chamber on the lower layer, the bearing air chamber and the damping air chamber are communicated through a speed regulating valve, and the air floatation top cover is arranged above the diaphragm. After the damping air chamber is filled with compressed air, the air enters the bearing air chamber through the speed regulating valve, and the air floatation top cover is jacked up after a diaphragm at the top of the bearing air chamber expands. The membrane air springs are generally mounted at the four corners of the equipment or platform and carry the weight of the equipment or platform through the air flotation caps.
When the existing film air spring works normally, the air floatation top cover of the film air spring is loaded through the compressed air inside, and an object is supported after the air floatation top cover is suspended. However, in the maintenance or installation stage, when the air spring is not inflated, the weight of the object above the air spring directly acts on the diaphragm of the air spring, and the elastic diaphragm needs to bear higher pressure at the fixing position of the pressing ring, so that the diaphragm is easily damaged, and the air spring cannot normally work.
Therefore, a self-supporting membrane air spring is designed, which can bear the weight by the base when the membrane air spring is not inflated, and avoid the damage of the membrane.

the diaphragm is fixed with the fixed ring through the pressing ring, and the upper opening of the cavity is sealed by the diaphragm;
the diaphragm divides the cavity below the diaphragm into two parts to form an upper bearing air chamber and a lower damping air chamber, the bearing air chamber and the damping air chamber are communicated through a speed regulating valve, and the damping air chamber is provided with an air inlet joint;
the air floatation top cover is arranged above the membrane, when the cavity of the base is not inflated, the air floatation top cover is positioned in the cavity of the base, and the upper end surface of the air floatation top cover is lower than that of the base.

Detailed Description
In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.
Example 1
As shown in fig. 1 and 2, a self-supporting film air spring comprises a base 1, a diaphragm 2, a partition plate 3, a pressing ring 4 and an air floatation top cover 5;
a cavity with an upper opening is arranged in the base 1, and a circle of convex fixing ring 101 is arranged on the upper part of the inner wall of the cavity;
the diaphragm 2 is fixed with the upper surface of the fixing ring 101 through the pressing ring 4, the upper opening of the cavity is sealed by the diaphragm 2, and the cavity above the fixing ring 101 is an accommodating cavity for accommodating the base 1;
the diaphragm 3 is fixed on the lower surface of the fixing ring 101 in a sealing manner, the diaphragm 3 divides the cavity below the diaphragm 2 into two parts to form an upper bearing air chamber 102 and a lower damping air chamber 103, the bearing air chamber 102 and the damping air chamber 103 are communicated through a speed regulating valve (not shown in the figure), and the damping air chamber 103 is provided with an air inlet joint (not shown in the figure);
