[0006] An upper-layer inner card formed by folding the main board, which includes a first receiving groove for placing articles provided on the upper end face;
[0007] A lower-layer inner card formed by folding the sub-board, disposed below the upper-layer inner card, and provided with a second receiving groove for placing articles.
[0008] The main board includes a central board, and four side boards are provided around the central board. After the four side boards are folded, they enclose with the central board to form the first receiving groove.
[0009] The sub-board includes a bottom board, and support boards are provided on both sides of the bottom board. The support boards are arranged perpendicular to the bottom board, and connecting plates are connected to the tail ends of the support boards. One of the connecting plates is integrally connected to one of the side boards.
[0010] The second receiving groove is disposed on the opposite surfaces of the central board and the bottom board.
[0011] Cutting slits are provided on the support boards, and part of the support boards are folded along the cutting slits to be flush with the connecting plates.
[0012] A packaging box includes a box body, and the box body is internally provided with a multi-layer integrated inner card structure as described above.
[0013] The beneficial effects of the present utility model are as follows: The present utility model provides a multi-layer integrated inner card structure and a packaging box. The integrally formed design reduces costs and losses, improves the quality of product packaging. When folding, no division of labor is required, and the packaging can be formed only by simple manual folding, without the need for other auxiliary forming materials such as glue, which simplifies the production process, reduces the labor intensity, and improves the production efficiency.

[0020] The present utility model will be further described below with reference to the accompanying drawings: As shown in the figure, a multi-layer integrated inner card structure includes a main board 1 and a secondary board 2 made of a cardboard, and further includes an upper inner card 11 formed by folding the main board, which includes a first receiving groove 111 provided on the upper end surface for placing articles;
[0021] A lower inner card 21, formed by folding the secondary board, is provided below the upper inner card and is provided with a second receiving groove 211 for placing articles. Both the upper inner card and the lower inner card can be used to prevent articles. The upper inner card can be flipped open to place the articles in the lower inner card. Moreover, the upper inner card and the lower inner card are made of a single cardboard, which includes a main board and a secondary board. The main board is used to fold to form the upper inner card, and the secondary board is used to fold to form the lower inner card. The integrally formed design reduces costs and losses, improves the quality of product packaging. When folding, no division of labor is required, and the packaging can be formed only by simple manual folding, without the need for other auxiliary forming materials such as glue, which simplifies the production process, reduces the labor intensity, and improves the production efficiency.
[0022] In this embodiment, as shown in the figure, the main board includes a central board 101, and four side boards 102 are arranged around the central board. After the four side boards are folded, they enclose with the central board to form a first accommodation groove. The side boards can be folded in a two-piece manner to form a "п" structure, or can be a single upwardly folded side board structure, and the first accommodation groove is formed therein.
[0023] In this embodiment, as shown in the figure, the auxiliary board includes a bottom board 201, support boards 202 are arranged on both sides of the bottom board, the support boards are arranged perpendicular to the bottom board, and a connecting plate 203 is connected to the tail end of the support board. One connecting plate is integrally connected to one side board. The bottom board folds vertically downward along the folding line 502 and then folds along the second folding line 501, thus forming the support boards (in the vertical direction) and the connecting plates (in the horizontal direction). One connecting plate is connected to the side board, and the connecting plate also plays a role in supporting the upper inner card at the same time. A second accommodation groove for placing materials is formed between the bottom board and the central board.
[0024] In this embodiment, as shown in the figure, the second accommodation groove is arranged on the opposite surfaces of the central board and the bottom board.
[0025] In this embodiment, as shown in the figure, cutting slits 204 are arranged on the support boards, and part of the support boards are folded along the cutting slits to be flush with the connecting plates. It is also possible to press down part of the support boards along the cutting slits, so that a small placement groove can also be formed on the back of the support boards that are not pressed down.
[0026] In this embodiment, as shown in the figure, a packaging box includes a box body 6, and a multi-layer integrated inner card structure as described above is arranged in the box body 6.
