as shown in fig. 6, the blocking block 37 is spherical, and the connecting position of the first air passage 9 and the second air passage 10 is provided with an arc-shaped groove 39 matching with the blocking block 37 in shape; during operation, spherical blocking piece 37 can reduce its produced resistance with pressure port 36 relative motion, and blocking piece 37 can impress under the effect of pressure port 36 atmospheric pressure simultaneously in the arc wall 39 of two air flue handing-over departments to can play more effectual shutoff effect to the gap of two air flue handing-over, further reduce revealing of 2 inside gas of case lid.

The working principle is as follows: when the box body 1 needs to place goods, the buffer film 13 is in a shrivelled state and is tightly attached to the inside of the buffer cavity 12 at the moment, the occupation of the storage space in the box body 1 is reduced, so that the goods can be easily placed in the box body 1, the buffer cushions 14 arranged on the box body 1 and the box cover 2 can reduce the damage to the goods during up-and-down vibration, after the goods are placed, the box cover 2 is covered on the box body 1 at the moment, then another box body 1 filled with the goods is placed on the box cover 2, so that the elastic film 3 at the top end of the box cover 2 is pressed, the piston 6 is pushed to move towards the bottom end of the sliding cavity 5 through the air pressure in the elastic film 3 until the air inlet groove 8 on the piston 6 is communicated with the communication groove 11, at the moment, the air in the elastic film 3 can flow into the buffer cavity 12 through the air inlet groove 8, the communication groove 11 and the two air passages, so that the buffer film 13 gradually bulges and can play a role of damping effect on the goods vibrated in the horizontal direction, when pressure is not applied to the top end of the box cover 2 any more, the elastic membrane 3 is jacked up along with the elastic block 4, at the moment, gas in the buffer cavity 12 can flow back to the interior of the elastic membrane 3 through the two air passages and the one-way valve 40 in the air return groove, so that the work of the transportation mechanism can be carried out in a reciprocating mode, and meanwhile, the elastic membrane 3 which is arranged at the top end of the box cover 2 and is bulged can further relieve the vibration of the box body 1 in the vertical direction; when the air inlet groove 8 is communicated with the communicating groove 11, at the moment, the air in the elastic membrane 3 can apply pressure to the slider 15 and the blocking body 18 after flowing into the first air passage 9, so that the air pressure difference between the inner end and the outer end of the slider 15 can push the slider 15 to move towards one side of the second air passage 10 until the slider 15 is attached to the limiting block 20, at the moment, the slider 15 can block the junction between the two air passages, the condition that the air flowing into the first air passage 9 leaks from the attachment part between the box body 1 and the box cover 2 is reduced, and meanwhile, when the air pressure in the first air passage 9 is continuously increased, the air pressure at the position can push the blocking body 18 open from the through groove 17, so that the through groove 17 is in an open state, and the air can effectively flow into the buffer cavity 12; when the sliding block 15 is gradually close to the limiting block 20, the limiting block 20 can attract the sliding block 15 and play a certain fixing effect, and a part of pulling force of the second spring 16 on the sliding block 15 is counteracted, so that the sliding block 15 can be more stably positioned at the joint position of the two air passages and more effectively block the joint position of the two air passages; when gas initially flows into the first air passage 9, the free end of the sliding plate 21 is positioned in the through groove 17 and blocks the through groove 17, so that the air pressure in the first air passage 9 can sufficiently exert acting force on the blocked sliding block 15 and promote the sliding of the blocked sliding block 15 in the two air passages, the situation that part of gas flows out of the through groove 17 to influence the efficient sliding of the sliding block 15 in the moving process of the sliding block 15 is reduced, when the sliding block 15 moves to be attached to the limiting block 20, the free end of the sliding plate 21 is separated from the through groove 17 and is not blocked any more, and the gas in the first air passage 9 can smoothly push the blocking body 18 open and flow out; after the box cover 2 is covered on the box body 1, the elastic membrane 3 is pressed by external pressure at the moment, so that the blocking ball 23 can be ejected from the funnel-shaped cavity after the gas flows into the two air passages, the gas smoothly flows into the buffer cavity 12, when the pressure is not applied to the elastic membrane 3 any more, the blocking ball 23 blocks the funnel-shaped cavity under the action of the elastic body 24 at the moment, the backflow of the gas in the buffer cavity 12 is reduced, the continuous pressure application to the box cover 2 is not needed any more, so that the top of the box body 1 can also effectively work under the action of not placing another box body 1, when the box body 1 needs to reset, the threaded rod 25 is gradually screwed into the first air passage 9 at the moment, the threaded rod 25 ejects the blocking ball 23 from the funnel-shaped cavity through the movement of driving the sliding block 15 and the ejector rod 26, so that the gas in the buffer cavity 12 can effectively backflow after the elastic membrane 3 resets, so that the work of the transportation mechanism can be carried out in a reciprocating way; lubricating oil is stored in the oil storage cavity 27 in advance, the conveying strips 28 can continuously adsorb the lubricating oil, and when the sliding plate 21 moves relative to the through groove 17, the conveying strips 28 can coat the lubricating oil in the through groove 17, so that the friction resistance generated when the sliding plate 21 moves relative to the through groove 17 is reduced, and the movement of the sliding block 15 can be performed more smoothly; when the sliding plate 21 is positioned in the through groove 17, the magnetic layer 29 attracts the magnetic blocks 30, so that the magnetic blocks 30 press the conveying strips 28 to be effectively attached to the side walls of the through groove 17 when approaching the inner wall of the through groove 17, and the conveying strips 28 stably coat lubricating oil on the through groove 17, when the free end of the sliding plate 21 is separated from the through groove 17, the two symmetrical magnetic blocks 30 are close to each other under the tension of the pull rope 31, and the conveying strips 28 are contracted in the oil conveying groove, so that the sliding plate 21 can be more stably inserted into the through groove 17, and the phenomenon that the conveying strips 28 are blocked with the through groove 17 due to the fact that the conveying strips protrude at the outer end of the sliding plate 21 is reduced; when the slide block 15 slides in the two air passages under the action of air pressure at one side, the slide block 15 can drive the roller 33 to roll on the inner walls of the two air passages, so that the friction resistance between the slide block 15 and the two air passages due to relative movement is greatly reduced, and meanwhile, the arranged roller 33 can isolate gas from flowing between the slide block 15 and the two air passages, so that the slide block 15 can slide more effectively under the action of the air pressure at one side; when the sliding block 5 is attached to the limiting block 20, the blocking piece 34 drives the pressure hole 36 to move to the joint of the first air passage 9 and the second air passage 10, at the moment, the gas flowing out of the through groove 17 can pass through the pressure groove 35 and the pressure hole 36 to apply pressure to the blocking block 37, so that the blocking block 37 is pressed at the joint of the two air passages, and the condition that the gas in the box cover 2 flows out of the gap to cause gas leakage is reduced; spherical plugging block 37 can reduce its produced resistance with pressure port 36 relative motion, and plugging block 37 can be impressed in the arc wall 39 of two air flue handing-over departments under the effect of pressure port 36 atmospheric pressure simultaneously to can play more effective shutoff effect to the gap of two air flue handing-over, further reduce the inside gaseous leakage of case lid 2.
