[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3As shown, this utility model provides a quick-assembly glue-free plug-in packaging box, including an outer packaging box 1. A first support pad 2 is glued to the bottom inner side of the outer packaging box 1, which can provide support and cushioning for the bottom of the inner packaging box 3. The top of the first support pad 2 supports the inner packaging box 3, which is plugged into the inner side of the outer packaging box 1. A cover plate 4 is hinged to one side of the inner wall of the outer packaging box 1. A second support pad 5 is glued to the bottom of the cover plate 4, which can provide support and cushioning for the top of the inner packaging box 3. Two top plates 6 are symmetrically hinged to the top of the outer packaging box 1. The top plates 6 abut against the top of the cover plate 4. The top of each of the two top plates 6 is connected to an elastic piece 7. A fastener 8 is nested in the middle of the left elastic piece 7. The middle of the right elastic piece 7 has a fastening hole for fastening the fastener 8. The two elastic pieces 7 can be fixed by fastening the fastener 8 into the fastening hole, thereby fixing the two top plates 6. The glue-free design allows for repeated assembly and disassembly.

[0021] Specifically, connecting blocks 9 are glued to the upper part of the front and rear outer walls of the outer packaging box 1, and connecting rods 10 are movably inserted into the inner side of the connecting blocks 9. Handles 11 are connected between the two ends of the connecting rods 10. The handles 11 can rotate relative to the connecting blocks 9 through the connecting rods 10, and the moving device can be easily lifted through the two handles 11.

[0022] Furthermore, a label 12 is attached to the left outer wall of the outer packaging box 1. The label 12 is marked with information about the contents of the inner packaging for easy and quick understanding. The label 12 is also covered with a protective film to prevent wear and tear and ensure that the information is clearly visible.

[0023] Furthermore, four support pads 13 are bonded to the bottom of the outer packaging box 1 in a rectangular shape, and the support pads 13 are flush with the corresponding side of the outer packaging box 1, which can prevent the bottom of the outer packaging box 1 from being worn.

[0024] It is worth noting that the bottom of the inner packaging box 3 is rectangularly distributed with four positioning rods 14 connected to it. The top of the first support pad 2 is constructed with positioning holes for inserting the positioning rods 14. The four sets of this structure ensure that the inner packaging box 3 will not shake horizontally during transportation.

[0025] It is worth noting that the top of the side wall of the positioning rod 14 has threads, and the bottom of the inner box 3 of the packaging has a positioning hole for screwing the positioning rod 14, which facilitates the disassembly and assembly of the positioning rod 14 and makes it easy to replace it when it is damaged.

[0026] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: Place the item inside the inner box 3, then place the inner box 3 inside the outer box 1. At this time, the positioning rod 14 will be inserted into the corresponding positioning hole. Then, flip the cover plate 4 so that the second support pad 5 supports the top of the inner box 3. Then flip the two top plates 6 on top and fix the two elastic pieces 7 by fastening the fasteners 8 into the fastener holes to fix the two top plates 6. Then, it can be moved by the carrying device of the two handles 11. Since the bottom and top of the inner box 3 are supported by the first support pad 2 and the second support pad 5 respectively, the inner box 3 will not shake in the vertical direction. The structure of the four sets of positioning rods 14 at the bottom of the inner box 3 inserted into the positioning hole makes it not shake in the horizontal direction. In addition, the double-layer structure of the inner box 3 and the outer box 1 can provide sufficient protection for the packaged items.
