[0042] The present embodiment provides a packaging box, which includes a box body and at least one group of cushioning corner protection packages, the cushioning corner protection packages are arranged in the box body, the size of the cushioning corner protection packages can be changed according to different products, so that the packaging box can perform cushioning packaging for different products, and the packaging box is more environmentally friendly.

[0043] like Figure 1-Figure 3As shown, the cushioning corner protection package is formed by folding an integrally formed cardboard. The cushioning corner protection package does not require the use of adhesives for bonding, and can be formed without setting buckles and lock holes. It is more environmentally friendly and beautiful. It should be mentioned that the cushioning corner protection package in this embodiment is formed by folding corrugated cardboard.

[0044] Specifically, the cushioning corner protection package includes a main body cardboard 1 and four groups of corner protections 2. Two groups of first folding marks 11 and two groups of second folding marks 12 are arranged on the main body cardboard 1. The two groups of first folding marks 11 are arranged at intervals along the length direction of the main body cardboard 1, and the two groups of second folding marks 12 are arranged at intervals along the length direction of the main body cardboard 1, and the two groups of second folding marks 12 are located between the two groups of first folding marks 11. The two groups of first folding marks 11 and the two groups of second folding marks 12 extend along the width direction of the main body cardboard 1. The cushioning corner protection package can change its internal size through the two groups of first folding marks 11 and the two groups of second folding marks 12, so that it can be suitable for products of three different sizes. The application scope of the cushioning corner protection packaging is widened; four groups of corner protectors 2 are respectively arranged at the four corners of the main paperboard 1, and the corner protectors 2 can protect a corresponding corner of the product. The corner protectors 2 include a first buffer structure 21, a second buffer structure 22 and a third buffer structure 23. The first buffer structure 21 can abut against the product and can buffer the product along the X direction; the second buffer structure 22 can abut against the product and can buffer the product along the Y direction; the third buffer structure 23 can abut against the product and can buffer the product along the Z direction; the corner protectors 2 can simultaneously buffer the impacts on the product in the X, Y and Z directions to protect the product.

[0045] like Figure 3 As shown, the first buffer structure 21 is formed by folding a first paperboard, the first paperboard includes a first wall panel 211, a first connecting panel 212, a first combined panel 213 and a second combined panel 214, one side of the first wall panel 211 is connected to the main paperboard 1, and the first connecting panel 212 is connected to the side of the first wall panel 211 away from the main paperboard 1; the first combined panel 213 includes a first panel 2131, a second panel 2132 and a third panel 2133 connected in sequence, one end of the first panel 2131 is connected to the first connecting panel 212; the second combined panel 214 includes a fourth panel 2141, a fifth panel 2142 and a sixth panel 2143 connected in sequence, and one side of the fourth panel 2141 is connected to the third panel 2133.

[0046] like Figure 3As shown, the second buffer structure 22 is formed by folding a second paperboard, and the second paperboard includes a second wall panel 221, a second connecting panel 222, a third connecting panel 223, a third combined panel 224 and a fourth combined panel 225. One end of the second wall panel 221 is connected to the first wall panel 211, the second connecting panel 222 is connected to an end of the second wall panel 221 away from the first wall panel 211, and one end of the third connecting panel 223 is connected to the second connecting panel 222; the third combined panel 224 includes a first sub-panel 2241, a second sub-panel 2242 and a third sub-panel 2243 connected in sequence, and one end of the first sub-panel 2241 is connected to the third connecting panel 223; the fourth combined panel 225 includes a fourth sub-panel 2251, a fifth sub-panel 2252 and a sixth sub-panel 2253 connected in sequence, and one end of the fourth sub-panel 2251 is connected to an end of the third sub-panel 2243 away from the third connecting panel 223.

[0047] like Figure 3 As shown, the third buffer structure 23 is folded from the third paperboard, and the third paperboard includes a fourth connecting plate 231, a fifth connecting plate 232, a fifth combined plate 233 and a sixth combined plate 234, the fourth connecting plate 231 is connected to the main paperboard 1, one end of the fifth connecting plate 232 is connected to the fourth connecting plate 231, the fifth combined plate 233 includes a first wing plate 2331, a second wing plate 2332 and a third wing plate 2333 connected in sequence, and one side of the first wing plate 2331 is connected to the fifth connecting plate 232; the sixth combined plate 234 includes a fourth wing plate 2341, a fifth wing plate 2342 and a sixth wing plate 2343 connected in sequence, and one end of the fourth wing plate 2341 is connected to the third wing plate 2333.

[0048] In order to enhance the strength of the corner protector 2 , the corner protector 2 in this embodiment is further provided with a reinforcing plate 24 , which is connected to the main paperboard 1 . When the first paperboard and the second paperboard are folded, the reinforcing plate 24 can overlap with the second wall panel 221 .

[0049] When the paperboard of the cushioning corner protection packaging is folded and assembled, first, the first combined board 213 and the second combined board 214 are folded into the first multi-layer paper spring structure 210, the third connecting board 223, the third combined board 224 and the fourth combined board 225 are folded into the second multi-layer paper spring structure 220, and the fifth connecting board 232, the fifth combined board 233 and the sixth combined board 234 are folded into the third multi-layer paper spring structure 230 (see Figure 4 ), and then fold the first wall panel 211, the second wall panel 221 and the reinforcing panel 24 (see Figure 5 ), and then fold the fourth connecting plate 231, the first connecting plate 212 and the second connecting plate 222 in sequence (see Figure 6 and Figure 7) so that the first multi-layer paper spring structure 210, the second multi-layer paper spring structure 220 and the third multi-layer paper spring structure 230 are mutually clamped (see Figure 8 ) to fold into corner guards 2. It is conceivable that the four groups of corner guards 2 can be folded separately in sequence or simultaneously.

[0050] from Figure 3 and Figure 4 It can be seen that the second multi-layer paper spring structure 220 and the third multi-layer paper spring structure 230 have seven layers of paperboard, while the first multi-layer paper spring structure 210 has only six layers of paperboard. Therefore, the assembled reinforcing plate 24 can also serve as the seventh layer of paperboard of the first multi-layer paper spring structure 210, so that the first multi-layer paper spring structure 210, the second multi-layer paper spring structure 220 and the third multi-layer paper spring structure 230 can provide the same cushioning.

[0051] It is conceivable that in order to adapt to products with different buffer strengths, the number of paperboards in the first multi-layer paper spring structure 210, the second multi-layer paper spring structure 220 and the third multi-layer paper spring structure 230 only needs to be greater than or equal to three layers (and the number of layers is a positive integer).

[0052] It is conceivable that the corner protector 2 in this embodiment can be disassembled and used separately.

[0053] It should be noted that the dotted lines in the accompanying drawings are folding marks of the cardboard of the cushioning corner protection packaging.
