Abstract

The invention belongs to the technical field of an air distribution bag and particularly relates to a compressed air distribution bag. The air distribution bag comprises an air distribution bag body,wherein fixing blocks are fixedly connected with ends, away from a rotating shaft, of the two arc-shaped blocks, threaded holes are formed on the fixing blocks, a threaded rod is arranged in the threaded holes in a matched manner, one end of the threaded rod is fixedly connected with a rotating block, a rubber soft cushion is fixedly connected with an inner wall of the arc-shaped block through a first spring, a base is arranged at a bottom end of the air distribution bag body, a first limiting block and a second limiting block are slidably connected with the base, a top end of a third spring is fixedly connected with a pull block, and a bottom end of the third spring is fixedly connected with an upper end face of the first limiting block. The air distribution bag has the advantages that through the arc-shaped block, the rubber soft cushion, the first limiting block, the second limiting block and the base, the air distribution bag can be conveniently connected with a connecting pipe, anair leakage phenomenon is effectively prevented, sealing performance is better, moreover, the air distribution bag is not prone to shaking, and stability is higher.

Description

technical field [0001] The invention relates to the technical field of air distribution bags, in particular to a compressed air distribution bag. Background technique [0002] The air distribution bag can adjust the compressed air, separate different air, and then lead them to different air distribution pipes, so that the compressed air can be effectively distributed. The compressed air distribution bag in the prior art The sealing performance of the air intake pipe and the air distribution pipe is not good, and leakage is prone to occur. Moreover, the compressed air distribution bag in the prior art is not stable, and it is easy to be knocked down by the operator, resulting in parts on the air distribution bag. damage. [0003] There are following problems in the compressed air distribution bag in the middle of the prior art: [0004] 1. In the compressed air distribution bag in the prior art, during long-term use, air leakage is prone to occur at the connection between t...
