At this time, the tensioning belt 5 can be pulled downward. After the pulling is completed, the pulling of the pulling plate 8 is released. At this time, under the elastic force of the first spring 28, the clamping end of the cross-shaped clamping rod 29 is clamped into the clamping hole 30 again, so that the winding wheel 9 cannot rotate;

[0034] like Figure 6 As shown, the limiting mechanism includes a T-shaped pull rod 34, the T-shaped pull rod 34 is slidably connected to the connecting cavity 33, the connecting cavity 33 is opened in the bottom plate 1, the T-shaped pull rod 34 is fixedly connected to one end close to the bottom plate 1 with a plurality of limiting rods 35, the limiting rod 35 is clamped in the limiting hole 36 at one end away from the T-shaped pull rod 34, and a plurality of limiting holes 36 are opened in the outer side of the tensioning belt 5, and the second spring 20 is sleeved on the outer side of the T-shaped pull rod 34, and one end of the second spring 20 is connected to the T-shaped pull rod The rod 34 is fixedly connected, and the other end is fixedly connected to the connecting cavity 33. The T-shaped pull rod 34 is pulled to compress the second spring 20, and the tension belt 5 is pulled downward to pass through the through slot 32. The bottom plate 1 and the top plate 10 are fitted with the surface of the box body 3 by tightening the tension belt 5. The pulling of the T-shaped pull rod 34 is released. At this time, under the elastic force of the second spring 20, the limiting rod 35 is clamped into the limiting hole 36, so that the tension belt 5 is fixed in the through slot 32;

[0035] like Figure 1 as well as Figure 2As shown, the sealing assembly includes four airbags 11. After being inflated, the four airbags 11 will be propped up and extended, and contact the storage groove 13. At the same time, the four airbags 11 will be in conflict with each other after being fully inflated. At this time, the box body 3 is in a sealed state. The four airbags 11 are arranged around the storage groove 13 and are fixedly connected to the storage groove 13. An air guide cavity 12 is opened in the box body 3. The air guide cavity 12 is respectively connected to the positioning hole 16, the positioning tube 14 and the airbag 11. Two T-shaped baffles 4 are arranged in the air guide cavity 12, and a through hole 16 is opened in the T-shaped baffle 4. The hole 26, one end of the T-shaped baffle 4 is slidably connected to the guide cavity 24, the guide cavity 24 is opened in the box body 3, and the guide cavity 24 is fixedly connected with a connecting spring 25, one end of the connecting spring 25 is fixedly connected to the T-shaped baffle 4, and the other end is fixedly connected to the guide cavity 24, the box door 7 is closed to allow the connecting ring 21 to enter the inner side of the box body 3, and the fixing screw 6 is rotated to be screwed into the box body 3, and the fixing screw 6 will push the T-shaped baffle 4 to move, so that the through hole 26 corresponds to the air guide cavity 12, so that the gas can enter the airbag 11 through the air guide cavity 12;

[0036] The blowing mechanism includes a blower 18. During the use of the blower 18, the corresponding size and model can be selected for use. The blower 18 is fixedly installed at the lower end of the bottom plate 1. The output end of the blower 18 is fixedly connected to the input end of the one-way valve 17. The one-way valve 17 is fixedly installed in the bottom plate 1. The output end of the one-way valve 17 is connected to the guide chamber 2. Through the setting of the one-way valve 17, the gas entering the air guide chamber 12 will not return to the blower 18. The guide chamber 2 is opened in the bottom plate 1, and the guide chamber 2 is connected to the positioning hole 16. Turning on the blower 18 allows external air to enter the one-way valve 17. The air entering the one-way valve 17 will enter the guide chamber 2. The air entering the guide chamber 2 will eventually enter the air guide chamber 12. After the gas enters the airbag 11, the airbag 11 will be propped up outward from the storage groove 13, and enter the sealing groove 22 through the four airbags 11, so that the box body 3 is in a sealed state.

[0037] like Figure 3As shown, two fixing screws 6 are movably connected in one side of the box door 7, which are screwed into the box body 3 through the fixing screws 6, so that the box door 7 is fixed. An internal threaded hole is provided on the outside of the box body, and the fixing screws 6 are screwed into the internal threaded hole, so that the box door 7 is fixed. At the same time, when the fixing screws 6 are screwed into the internal threaded hole, the T-shaped baffle 4 will be pushed to move. A rubber plug 23 is fixedly connected to one end of the box door 7 close to the box body 3, and the rubber plug 23 is clamped in the exhaust hole 19. The exhaust hole 19 is connected to the air guide cavity 12. In the process of closing the box door 7, the rubber plug 23 is clamped in the exhaust hole 19 to block the exhaust hole 19. When the box door 7 is pulled outward, the rubber plug 23 will immediately move out of the exhaust hole 19. At this time, the gas in the airbag 11 will be discharged into the external environment through the exhaust hole 19. At the same time, the airbag 11 will be re-collected into the storage groove 13 under the action of its own elastic force. At this time, the box door 7 can be fully opened.

[0038] Working principle: when in use, the boxes 3 are placed between the bottom plate 1 and the top plate 10 in sequence according to the number of boxes 3 to be used. Specifically, the two positioning tubes 14 connected to the lower ends of one set of boxes 3 are inserted into the two positioning holes 16 at the upper end of the bottom plate 1. After the insertion is completed, the two positioning tubes 14 connected to the lower ends of the other set of boxes 3 are inserted into the positioning holes 16 at the upper end of the installed boxes 3. The two fixing rods 15 at the lower end of the top plate 10 are clamped into the positioning holes 16 in the upper end of the upper box 3. After the installation is completed, The pull plate 8 is pulled outward to drive the cross-shaped clamping rod 29 to disengage from the clamping hole 30, so that the winding wheel 9 is in a movable state, and the T-shaped pull rod 34 is pulled to compress the second spring 20, and the tension belt 5 is pulled downward to pass through the through slot 32. By tightening the tension belt 5, the bottom plate 1 and the top plate 10 are fitted with the surface of the box body 3, and the pulling of the T-shaped pull rod 34 is released. At this time, under the elastic force of the second spring 20, the limit rod 35 is clamped into the limit hole 36, so that the tension belt 5 is fixed in the through slot 32;

[0039] The box door 7 is closed to allow the connecting ring 21 to enter the inner side of the box body 3, and the fixing screw 6 is rotated to be screwed into the box body 3. At the same time, the fixing screw 6 will push the T-shaped baffle 4 to move so that the through hole 26 corresponds to the air guide cavity 12. At the same time, in the process of closing the box door 7, the rubber plug 23 will be snapped into the exhaust hole 19 to block the exhaust hole 19, and the blower 18 is turned on to allow external air to enter the one-way valve 17. The air entering the one-way valve 17 will enter the guide cavity 2, and the air entering the guide cavity 2 will eventually enter the air guide cavity 12. After the gas enters the airbag 11, the airbag 11 will be propped up from the storage groove 13 to the outside, and enter the sealing groove 22 through the four airbags 11, so that the box body 3 is in a sealed state;

[0040] The box door 7 can be opened by rotating the fixing screw 6 to cancel its threaded connection with the box body 3. At the same time, in the process of rotating the fixing screw 6 outward, the T-shaped baffle 4 will move outward under the elastic force of the connecting spring 25. At this time, the through hole 26 and the air guide cavity 12 are staggered to prevent the gas in other boxes 3 from being discharged. When the box door 7 is pulled outward, the rubber plug 23 will immediately move out of the exhaust hole 19. At this time, the gas in the airbag 11 will be discharged into the external environment through the exhaust hole 19. At the same time, the airbag 11 will be re-received into the storage groove 13 under the action of its own elastic force. At this time, the box door 7 can be fully opened.

[0041] The above embodiments are only used to help understand the method and core idea of ​​the present invention.
