[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: Refer to Figure 1 A highly protective packaging box is shown, comprising a box body 1 and a box cover 2 . An opening is provided at one end of the box body 1 , and the box cover 2 is arranged on the outside of the box body 1 and is used to seal the end opening of the box body 1 .

[0025] Reference Figure 2 、 Figure 3 and Figure 4 As shown, the inner wall of the box body 1 is paved with multiple air bags 3, a base 5 is fixed to one end of the box body 1, and an air control chamber 501 connected to the air bags 3 is opened in the base 5. In specific implementation, an air cavity 4 connected to the multiple air bags 3 is opened in the inner wall of the box body 1, and one end of the air cavity 4 is connected to the inside of the air control chamber 501.

[0026] At the same time, a screw 8 is rotatably mounted within the air control chamber 501. A sealing plate 9 is threadedly sleeved on the screw 8. Sealing oil is provided between the screw 8 and the sealing plate 9 to ensure that the sealing plate 9 effectively seals and isolates the air control chamber 501 without affecting the movement of the sealing plate 9. To ensure the effective movement of the sealing plate 9 driven by the screw 8, the edge of the sealing plate 9 slides against the inner wall of the air control chamber 501 to form a limit.

[0027] In summary, the sealing plate 9 can be driven to move in the air control chamber 501 by rotating the screw 8, so that the sealing plate 9 can squeeze the air inside the air control chamber 501 to make the airbag 3 swell, so that the expansion of the airbag 3 can be used to cushion and protect the items stored in the box body 1, thereby improving the protection effect.

[0028] One end of the screw rod 8 extends out of the outside of the box body 1 and is fixed with a rotating wheel 7, so that the user can rotate the screw rod 8 outside the base 5. Specifically, the middle of one side of the base 5 away from the box body 1 allows the end of the screw rod 8 fixed with the rotating wheel 7 to pass through, and the middle of this side of the base 5 is provided with a mounting groove 6 for the rotating wheel 7 to be rotatably mounted.

[0029] Reference Figure 1 and Figure 5 As shown, an abutment plate 11 for extending into the box body 1 is elastically installed in the box cover 2. Specifically, a spring 10 is fixed on the inner wall of the box cover 2 away from the box body 1, and the abutment plate 11 is fixed on the spring 10. A soft pad 12 is installed on the side of the abutment plate 11 away from the spring 10. The soft pad 12 can be made of but not limited to soft materials such as sponge.

[0030] The working principle of this utility model is as follows: when using this highly protective packaging box, articles can be stored in the box body 1, and then the rotating wheel 7 is rotated as needed to drive the screw 8 to rotate, thereby driving the sealing plate 9 to move in the air control chamber 501, so that the sealing plate 9 can squeeze the air in the air control chamber 501 into the airbag 3, causing it to expand and abut against the articles in the box body 1, thereby improving the protection effect of the articles in the box body 1.

[0031] At the same time, after closing the box cover 2, the abutment plate 11 in the box cover 2 will extend into the box body 1 under the action of the spring 10, and abut the items in the box body 1 through the cushion 12, which can further ensure the protection effect of the items in the box body 1.

[0032] When the box body 1 needs to store more items, the sealing plate 9 can be driven to increase the space inside the control air chamber 501 that is connected to the airbag 3, so that the airbag 3 is deflated and the volume inside the box body 1 is reduced, so as to store more items and be flexible in use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
