The bag type air spring has many advantages compared with the common steel spring, is widely applied to various fields as a vibration isolation element at present, and can be used for simulating rigidity according to the self-bearing characteristic of the bag type air spring. When the bag type air spring is used for carrying, sometimes because of the requirement of a stroke, under the condition that a single air spring cannot meet the stroke, two or more air springs are connected in series through connecting end plates to form an air spring group. But in the event of such large deformations could easily cause the air spring set to deflect off the central axis, causing instability, as shown in figure 3.
In order to prevent the instability, the most common method at present is to penetrate a pull rod at a connecting end plate of the air spring, fix the pull rod, restrain the air spring group from moving along a central axis, and prevent the instability of the device. However, this method has the following drawbacks: 1. the method utilizes the pull rod to restrain the movement of the air spring group, and external force exists, so that additional load can be generated, and the load precision of the whole air spring group is influenced; 2. the method is only suitable for the situation of vertical movement of the air spring set, and the instability of the air spring set cannot be effectively prevented under the movement situation with an inclined angle.

The invention aims to provide a method for preventing an air spring set from being unstable, which realizes the stable application of load under a large stroke of the air spring set.
The invention provides an anti-instability air spring set which mainly comprises an air spring, a cover plate, a connecting end plate and a telescopic rod. Wherein the cover plates at the two ends of the air spring are connected with the outside; the telescopic rod penetrates through the middle of the connecting end plate and is in clearance fit with the connecting end plate, two ends of the telescopic rod are hinged with the air spring cover plate respectively, and the whole system forms a closed whole. Specifically, as shown in fig. 1 and 2, the method mainly includes:
one end of the first air spring 1 is connected with the first cover plate 3, and the other end of the first air spring is connected with the end plate 5;
one end of the second air spring 2 is connected with the second cover plate 4, and the other end of the second air spring is connected with one surface of the end plate 5, which is far away from the first air spring 1;
the telescopic rod 6 is composed of a plurality of sleeves, one end of the telescopic rod is hinged on the first cover plate 3, and the other end of the telescopic rod is hinged on the second cover plate 4;
the end plate 5 is provided with a through hole, and the telescopic rod 6 penetrates through the through hole and is in clearance fit with the end plate 5.
In this embodiment, a hinge point between the telescopic rod 6 and the first cover plate 3 is located at the center of the first cover plate 3; the hinge point of the telescopic rod 6 and the second cover plate 4 is located in the center of the second cover plate 4, referring to fig. 1, the telescopic rod 6 is the central axis of the anti-destabilization air spring set, and the stability of the structure is further facilitated.
It will be appreciated that for added stability, a plurality of telescopic rods may also be provided, with the axes of the telescopic rods 6 being parallel to one another.
In this embodiment, the telescopic rod 6 is disposed in a sealed cavity formed by the first air spring 1 and the second air spring 2, referring to fig. 1 and 2.

In an alternative embodiment, two ends of the telescopic rod 6 are connected with the first cover plate 3 and the second cover plate 4 through spherical hinges.
In the loading process, as the cover plate is connected with the outside, the air spring is compressed when the load is applied, and meanwhile, the telescopic rod is contracted, and the connecting end plate is constrained to move along the central axis in the contraction process, so that the instability of the device in the movement process is effectively prevented.
The telescopic rod is hinged with the air spring cover plate, the whole system forms a whole without the influence of external force, and therefore the generation of additional load is avoided in the loading process.
