[0032] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0033] Embodiment 1:

[0034] like Figure 1-4As shown, a packaging box with a self-supporting lining comprises a first side panel 1, a second side panel 2, a third side panel 3, and a fourth side panel 4 which are connected in sequence and used to be folded into an up-and-down through-type cavity; a bottom panel 5 provided at the bottom of the first side panel 1 and used to fold and close the bottom of the up-and-down through-type cavity; a first top panel 6 provided at the top of the third side panel 3 and used to fold and close the top of the up-and-down through-type cavity; a first supporting lining area 7 provided at the bottom of the second side panel 2 and used to be folded and parallel to one end of the bottom panel 5; a second supporting lining area 8 provided at the bottom of the fourth side panel 4 and used to be folded and parallel to the other end of the bottom panel 5; a third supporting lining area 9 provided at the top of the second side panel 2 and used to be folded and parallel to the inner side of the first top panel 6; and a second top panel 10 provided at the top of the fourth side panel 4 and used to be folded and engaged with the third supporting lining area 9. This technical solution uses the first support lining area 7 and the second support lining area 8 provided on one side of the second side plate 2 and the fourth side plate 4 as the bottom of the product support, and the third support lining area 9 and the second top plate 10 provided on the other side of the second side plate 2 and the fourth side plate 4 as the top of the product limit, so that the product is further limited in the space formed by the first support lining area 7, the second support lining area 8, the third support lining area 9 and the second top plate 10, thereby avoiding damage during transportation. In addition, the one-piece structure improves the efficiency of assembling the packaging box with its own support lining and reduces manpower.

[0035] The first supporting lining area 7 includes a first supporting lining bottom panel 7-1 connected in sequence to the bottom of the second side panel 2 and used for folding and being parallel to the bottom panel 5, a first supporting lining side panel 7-2 used for folding and being parallel to the second side panel 2, a first supporting lining top panel 7-3 used for folding and being parallel to the first top panel 6, and a first supporting lining pasting portion 7-4 used for folding and being in contact with the second side panel 2. Under the height limit after the first supporting lining side panel 7-2 is folded, the bottom of the packaging box is raised. The second supporting lining area 8 includes a second supporting lining bottom panel 8-1 connected in sequence to the bottom of the fourth side panel 4 and used for folding and being parallel to the bottom panel 5, a second supporting lining side panel 8-2 used for folding and being parallel to the fourth side panel 4, a second supporting lining top panel 8-3 used for folding and being parallel to the first top panel 6, and a second supporting lining pasting portion 8-4 used for folding and being in contact with the fourth side panel 4. Under the height limit after the second supporting lining side panel 8-2 is folded, the bottom of the packaging box is also raised. In order to make the product in a horizontal position, the height of the first support lining side panel 7-2 after folding is consistent with the height of the second support lining side panel 8-2 after folding. The third support lining area 9 includes a third support lining top panel 9-1 connected in sequence to the top of the second side panel 2 and used to fold parallel to the first top panel 6, a third support lining side panel 9-2 used to fold parallel to the second side panel 2, a third support lining bottom panel 9-3 used to fold parallel to the bottom panel 5, and a third support lining adhesive portion 9-4 used to fold and fit with the second side panel 2. Under the height limit of the third support lining side panel 9-2 after folding, the top of the packaging box is lowered. Therefore, the space composed of the first support lining area 7, the second support lining area 8, the third support lining area 9 and the second top panel 10 is smaller than the space of the packaging box, which reduces the shaking space of the product during transportation and also reduces the degree of damage to the product during transportation.

[0036] The first support lining area 7, the second support lining area 8 and the third support lining area 9 are all cavity structures. Therefore, the technical solution enhances the support strength of the sides, top or bottom by providing a plurality of strong ribs 11 on the first support lining side panel 7-2, the first support lining top panel 7-3, the second support lining side panel 8-2, the second support lining top panel 8-3, the third support lining side panel 9-2 and the third support lining bottom panel 9-3, so that the height of the cavity three-dimensional structure formed by the first support lining area 7, the second support lining area 8 and the third support lining area 9 after folding remains unchanged.

[0037] In order to further reinforce the three-dimensional structure of the hollow cavity formed by the first supporting lining area 7, the second supporting lining area 8 and the third supporting lining area 9 after folding, the several strong ribs 11 on the first supporting lining side panel 7-2 are arranged in parallel and their length direction after folding is perpendicular to the first supporting lining top panel 7-3, and the several strong ribs 11 on the first supporting lining top panel 7-3 are arranged in parallel and their length direction after folding is perpendicular to the first supporting lining side panel 7-2. The several strong ribs 11 on the second supporting lining side panel 8-2 are arranged in parallel and their length direction after folding is perpendicular to the second supporting lining top panel 8-3, and the several strong ribs 11 on the second supporting lining top panel 8-3 are arranged in parallel and their length direction after folding is perpendicular to the second supporting lining side panel 8-2. The several strong ribs 11 on the third support inner lining side panel 9-2 are arranged in parallel and their length direction after folding is perpendicular to the third support inner lining bottom panel 9-3. The several strong ribs 11 on the third support inner lining bottom panel 9-3 are arranged in parallel and their length direction after folding is perpendicular to the third support inner lining side panel 9-2.

[0038] The second top plate 10 is provided with a second top plate engaging portion 10-1 on a side away from the fourth side plate 4, and a notch 12 for cooperating with the second top plate engaging portion 10-1 is provided at the connection between the third support lining top plate 9-1 and the third support lining side plate 9-2, such as the front edge of the second top plate engaging portion 10-1 can overlap the notch 12 or be embedded in the notch 12. The second top plate 10 is engaged with the third support lining area 9 to form a second top portion, which limits the height of the product on the one hand, and also achieves the effect of double protection of the product on the other hand.

[0039] In addition, in order to facilitate the assembly and molding of the packaging box, the first side panel 1 is further provided with a first adhesive portion 1-1 on the side away from the second side panel 2 for folding and fitting with the fourth side panel 4 to form a vertical through-type cavity that is tightly connected.
