When the lower carriage plate 3 moves to the lowest part, the lower surface of the lower carriage plate 3 abuts against the upper surface of the bottom plate 101, the axial movement of the screw rod pipe 301 is blocked, so that the screw rod 202 drives the screw rod pipe 301 to synchronously rotate, and the gear 303 and the rack 306 are utilized, so that the fixing rod 305 moves towards the inner side of the carriage body 1, the lower carriage plate 3 is pulled towards the inner side of the carriage body 1, when the lower carriage plate 3 abuts against the end part of the connecting rod 304, the moving position of the lower carriage plate 3 is limited, at the moment, the upper carriage plate 2 and the lower carriage plate 3 are closed, as shown in fig. 4, and the closing between the side carriage plate and the carriage body 1 is realized.
Further, sealing strips or dust-proof brush strips and the like are arranged on two sides of the upper compartment plate 2, and are used for sealing the space between the upper compartment plate 2 and the upright post 103 through the sealing strips or the dust-proof brush strips, and the fixing rod 305 is guaranteed to move between the upper compartment plate 2 and the upright post 103.
Meanwhile, the lower surface of the lower carriage plate 3 is provided with a plurality of bull-eye wheels, so that when the lower surface of the lower carriage plate 3 is abutted to the bottom plate 101, the horizontal movement can be realized through the bull-eye wheels, and the reliability and stability of the overall action are improved. And, there is the guard shield board lower carriage board 3 medial surface through the screw, and lead screw pipe 301 is located the guard shield board, through the guard shield board to the holistic protection of lead screw pipe 301, gear 303 and dead lever 305, avoids receiving the condition emergence of the goods influence in the carriage railway carriage or compartment body 1.
