[0032] As shown in the drawings, Figure 2 and Figure 4 As shown in the drawings, the outer box body comprises a cylindrical outer box body 7 and a box cover 1 arranged at both ends of the outer box body 7, the box cover 1 is provided with a box cover card convex 11, the outer box body 7 is provided with a box cover card slot, and the box cover card convex 11 is matched with the box cover card slot to fix the box cover 1 on the outer box body 7. The box cover 1 comprises an inner wall and an outer wall, and the inner wall and the outer wall surround a sealed air cavity, and the box cover 1 is made of PVC (polyvinyl chloride), rubber, PE (polyethylene) or PET (polyethylene terephthalate) and the like.

[0033] The inner surface of the outer box body 7 is provided with an outer box body air bag 20, and the first inner box body 4 and the second inner box body 5 are buckled in the outer box body air bag 20.

[0034] The box cover 1 is internally provided with a accessory box, and the accessory box comprises an accessory cavity 2 and an accessory cavity cover 3. The accessory cavity 2 is open on one side, the accessory cavity cover is fixed to the open side of the accessory cavity 2 through a buckle structure, and the accessory cavity 2 is fixed to the box cover 1 through the buckle structure.

[0035] A sealing ring 6 made of silica gel is arranged between the box cover 1 and the outer box body 7, and the box cover 1 and the outer box body 7 are buckled to form a sealed cavity, so that water vapor in the external environment cannot enter the inside of the packaging box, thereby playing a waterproof and moisture-proof role.

[0036] The outer box body 7 has a handle slot 17, and a handle 9 is arranged in the handle slot 17 through a pulling structure.

[0037] As shown in the drawings, Figure 2 , Figure 4 and Figure 5 As shown in the drawings, the pulling structure comprises a handle limiting column 21, a handle slot T-shaped guide rail 14 arranged on the side wall of the handle slot 17, and at least one level of pulling piece 10 arranged between the handle 9 and the handle slot 17. The handle limiting column 21 is fixed to the handle 9, the pulling piece 10 is provided with a pulling piece T-shaped guide rail 15, the pulling piece 10 is fixedly provided with a pulling piece limiting column 16, the pulling piece limiting column 16 of the level of pulling piece 10 close to the handle slot 17 is slidably connected with the handle slot T-shaped guide rail 14, the handle limiting column 16 is slidably connected with the pulling piece T-shaped guide rail 15 of the level of pulling piece 10 close to the handle 9, and the pulling piece limiting column 16 of the pulling piece 10 is slidably connected with the pulling piece T-shaped guide rail 15 of the adjacent pulling piece 10.

[0038] The handle limiting post 16, the pull-out component 10, and the handle groove T-shaped guide rail 14 each include a vertical guide rail portion and a horizontal guide rail portion, which are connected.

The valve plate 24 covers the inner end opening of the valve body 22. The spring 25 is located between the valve plate 24 and the valve body 22.

[0042] During inflation, the inflation head of the inflation tube opens to the outer end connected to the valve body 22. Simultaneously, the inflation head pushes the valve stem 23 inward, causing the valve plate 24 to separate from the valve body 22. The inflation valve opens, and the compressed gas in the inflation tube enters the airbag after passing through the inflation valve. After reaching the required inflation volume, the inflation head is removed. At this point, under the action of the internal and external pressure difference, the gas inside the airbag pushes the valve plate 24 outward, covering the inner end of the valve body 22. The inflation valve closes, preventing gas leakage.
