The activity structure drives the grid plate. At the same time, the grid plate is fixed at the top by a first rotating shaft. The grid plate can be opened and closed by controlling the rod to rotate the transmission rod, thereby changing the direction of the grid plate.

During the disassembly and maintenance of the cloth bag air pipe, multiple hoist buckle structures on the cloth bag air pipe need to be disassembled, which makes the disassembly and maintenance of the air duct more troublesome.

[0005] Therefore, a decentralized cold storage top air duct is proposed to solve the problem of disassembling and maintaining the cloth bag air pipe, which requires disassembling multiple hoist buckle structures on the cloth bag air pipe, making the disassembly and maintenance of the air duct more troublesome.
