Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1-2, the present invention comprises: the device comprises a lower cover plate 1 and an upper cover plate 2, guide cylinders 3 are arranged at four corners of the upper surface of the lower cover plate 1, guide posts 4 are arranged at four corners of the lower surface of the upper cover plate 2, the guide cylinders 3 and the guide posts 4 perform vertical guide motion on the same vertical line,

In the present embodiment, the positioning column 5 and the air nozzle 8 are preferably connected by a screw thread.

In this embodiment, it is preferable that the lower cover plate 1 is provided with a groove along the center of the upper surface, and the rubber bladder 6 is embedded in the groove.

In this embodiment, it is preferable that the rubber bladder 6 is sleeved with a limiting ring 12, and the limiting ring 12 is located at the joint of the rubber bladder 6 and the lower cover plate 1.

In this embodiment, it is preferable that a hexagonal nut 13 is further sleeved on the bolt 9, and the hexagonal nut 13 is located on the upper surface of the upper cover plate 2.

In this embodiment, the upper cover plate 2, the second buffer plate 10, the helmet 11, the air nozzle 8, the first buffer plate 7, the rubber bladder 6 and the lower cover plate 1 are preferably attached to each other.

The working principle is as follows: the during operation, at first the upper cover plate atress can extrude downwards, the upper cover plate exerts pressure to the guide post through the guide post, partly pressure can be alleviated to second buffer board and helmet simultaneously, then the air nozzle compresses, the in-process of compression can extrude downwards, partly pressure can be alleviated to first buffer board, then the rubber bag compresses and exerts pressure downwards, the apron exerts pressure to the guide post through the guide post simultaneously down, form a closed circulation, therefore, this compound bumper shock absorber of bag formula compressive shock absorber pressure resistance can be strong, bearing capacity preference.
