[0026] Embodiment 1

[0027] Reference Figures 1 to 3 As shown, a packaging partition, the main body of the packaging partition is an integrated structure, Figure 1 A whole rectangular paperboard 100 is folded to form a Figure 2 and Figure 3 The body is provided with a central part 11, an outer supporting part 12, an inner supporting part 13, and a loading part 14, and the outer supporting part 12, the inner supporting part 13, and the loading part 14 are distributed on the left and right sides of the central part, and the central part 11, the outer supporting part 12, the inner supporting part 13, and the loading part 14 are separated by crease lines.

[0028] The length of the outer support part 12 is equal to the length of the inner support part 13. The outer support part 12 and the inner support part 13 are arranged side by side by bending and protrude from the same side of the center part. The outer support part 12 and the inner support part 13 are perpendicular to the center part. The object-carrying part 14 is curled in a ring shape. The bottom of the curled object-carrying part 14 is fixedly connected to the center part 11, and the top of the curled object-carrying part 14 faces the area between the two inner support parts. Figure 2 and Figure 3 As shown, the loading part 14 supports the bottom surface of the product, and the inner supporting part 13 acts on the side of the product so that the product is wrapped in three directions; and the curled structure of the loading part 14 and the double-layer structure of the outer supporting part 12 and the inner supporting part 13 can effectively protect the product.

[0029] As an embodiment, the loading part 14 includes a bottom plate part 141, an elevated part 142, a bearing part 143, and a connecting part 144. The bottom plate part 141 is connected to the inner supporting part 13, and the bottom plate part 141, the elevated part 142, the bearing part 143, and the connecting part 144 are separated by crease lines. The length of the bottom plate part 141 is equal to the length of the bearing part 143, and the length of the elevated part 142 is less than the length of the inner supporting part 13. The connecting part 144 is located on one side of the inner supporting part 13 by bending the bottom plate part 141, the elevated part 142, and the bearing part 143 in the same bending direction, and the connecting part 144 is fixedly connected to the inner supporting part 13, and the bottom plate part 141 is fixedly connected to the central part 11. The above technical features make the loading part 14 square in shape and not occupy too much space, so that the partition in the standby state has a compact and flat structural feature, which is convenient for storage and transportation, and also convenient for product placement.

[0030] Furthermore, the central part is provided with a through hole I 111, and the bottom plate part is provided with a through hole II 1411. After molding, the center of the through hole I and the center of the through hole II are in the same straight line direction. This is because in the product packaging process, in order to transport the partition, a support rod is provided on the transport component, and the support rod passes through the through hole I and the through hole II, so that the partition is transported along with the transport component.

[0031] In order to facilitate the placement of the partition, the body is also provided with a hand-held portion 15, which is located between the outer support portion 12 and the inner support portion 13. The length of the hand-held portion 15 is less than the length of the central portion, and a cavity 16 is formed between the outer support portion 12, the hand-held portion 15, and the inner support portion 13. The setting of the hand-held portion 15, on the one hand, forms a cavity between the outer support portion 12 and the inner support portion 13, which is beneficial to the product buffering and shock absorption. On the other hand, the outer support portion 12 is provided with a through hole III 121 directly connected to the cavity 16. The through hole III 121 is roughly rectangular, and a finger can be inserted into the through hole III 121, so that the partition and the product thereon can be conveniently taken out of the packaging box. The length of the hand-held portion 15 should not be too long, so that the gap between the outer support portion 12 and the inner support portion 13 is not too large, and the width of the partition in the standby state is not too large, which is convenient for storage and transportation.

[0032] like Figure 1 As shown, before the partition is formed, a through hole I 111, a through hole III 121 and a through hole II 1411 have been formed on a whole rectangular paperboard. In addition, crease lines are also marked to facilitate bending during the manufacturing process, and the dotted lines in the figure are crease lines.

[0033] Embodiment 2

[0034] A packaging partition expansion method, such as Figures 4 to 6 As shown, first, the packaging partition is preliminarily bent to a standby state.

[0035] Then, if Figure 7 As shown, the spatial posture of the central part 11 is fixed, and the two outer supporting parts 12 are bent toward one side of the central part 11 until a cavity with a rectangular cross-section is formed between the inner supporting part 13, the bottom plate part 141, the increased part 142, and the bearing part 143.

[0036] Furthermore, while the outer supporting portion is bent, a force is applied to the load-bearing portion through the central portion to facilitate the load-bearing portion to move away from the central portion.

[0037] It can be understood from the above embodiments that the packaging partition of the present invention is formed by folding a whole piece of cardboard, avoiding the original process and structure of processing and reassembling multiple parts separately, simplifying the manufacturing method and structure, and reducing costs.

[0038] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
