A vacuum bellows to prevent leakage after impact

Abstract

This utility model relates to the field of vacuum bellows technology and discloses a vacuum bellows for preventing leakage after collision. It includes a buffer layer and two fixed pipes. Pipe mechanisms are provided on both the left and right sides of the buffer layer for leak prevention. Connecting mechanisms are provided on the opposite sides of the two fixed pipes for connecting the bellows. A protective mechanism is provided on the outside of the buffer layer. The pipe mechanisms include multiple A-layers, which are fixedly connected to each other on the left and right sides of the buffer layer. Two B-layers on the left side are fixedly connected to the right side of the two A-layers. In this utility model, the A-layers are fixed to both sides of the buffer layer, and the B-layers are connected to adjacent A-layers on their left and right sides. The A and B-layers are connected to a protective layer, which contains an internal bellows. A buffer assembly is provided on the outer wall of the buffer layer. The A and B-layers are alternately connected to form a main body that combines flexibility and strength.
