Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1 to 4, the present utility model provides a technical solution: the utility model provides an air formula anticollision mound, including pier stud 1, pier stud 1's outside cover is equipped with buffering gasbag cover 2, buffering gasbag cover 2 is located pier stud 1's periphery, this buffering gasbag cover 2's top is provided with gasbag shutoff 3, go up gasbag shutoff 3 and be located pier stud 1's top, buffering gasbag cover 2 and go up gasbag shutoff 3 and make whole pier stud 1 be included completely, can cushion the protection to the impact of arbitrary direction from this, buffering gasbag cover 2's cover internal fixation is provided with catching groove 21, pier stud 1's periphery wall fixation is provided with the annular spacing collar 11 that matches with catching groove 21, before the inflation, establish buffering gasbag cover 2 cover in pier stud 1's outside, with the outside of catching groove 21 corresponding buckle at annular spacing collar 11, when inflating the air cock on buffering gasbag cover 2, buffering gasbag cover 2 inflation at this moment, catching groove 21 can only extrude on annular spacing collar 11, whole buffering gasbag cover 2 and post 1 fixed connection, can cushion the impact of arbitrary direction under buffering gasbag cover 2 and the effect of last gasbag shutoff 3.
