It should be noted that, when selecting five-layer corrugated board such as AB flute type corrugated board or other thick (for example, the board thickness exceeds 5 mm) cardboard, the folding process is difficult and easy to damage the cardboard, the reason is that the cardboard with large board thickness is folding, when the adjacent cardboard structure is turned over relatively and needs to realize a large break angle (for example, close to 90 degrees) between the two, must exert bigger squeezing action to the structure of the junction of the adjacent boards to make its structure produce extrusion deformation, not only the force application process is difficult to control, but also the core paper and the stupefied core structure are damaged seriously during the extrusion. For example, as shown in fig. 2, in the structure, any two adjacent side surfaces of four side surfaces in the box flattening structure need to be perpendicular to each other when being folded and formed, at this time, the cardboard formed into the two side surfaces is folded to make the structures of the two formed side surfaces adjacent and perpendicular to each other, the included angle between the two side surfaces is 90 degrees, the cardboard structure at the joint of the two side surfaces is severely deformed due to large extrusion, both the core paper and the corrugated core are severely damaged to cause damage in the folding area, or even if the inner paper and the face paper are not damaged, the box has a large hidden damage risk due to damage of the core structure, after the internal articles are placed, the box is easily collapsed and collapsed or is directly cracked from the side when bearing the box.

In order to solve the above problems, the present invention may be further configured as follows: as shown in fig. 5, adjacent sides of the four front, rear, left and right sides of the box body are connected by at least one folding buffer plate, wherein the left side and the front side, the left side and the rear side, and the rear side and the right side of the four sides are connected by the folding buffer plate.

Specifically, when a paperboard formed into the box body is cut, the box body flattening structure is cut according to the structure shown in fig. 5, wherein folding buffer plates are arranged at the joints of the adjacent side surfaces (between the left side surface and the front side surface, between the left side surface and the rear side surface, and between the rear side surface and the right side surface), the adjacent side surfaces are not directly turned over with each other through the folding buffer plates, but are respectively turned over with the folding buffer plates, so that an included angle of 135 degrees is formed between the two turned over side surfaces, and in the structure shown in fig. 5, the rear side surface 102 and the right side surface 104 are connected through a first folding buffer plate 501; fig. 6 shows the junction between two adjacent sides of the box body in the box body after being folded, and in this partial structure, the back side 102 forms an angle of 135 degrees with the first folding buffer board 501, and the right side 104 forms an angle of 135 degrees with the first folding buffer board 501.

In addition, the longitudinal lining plate can be connected with the bottom inner plate through a second folding buffer plate, and the transverse lining plate is connected with the bottom outer plate through a third folding buffer plate.

In some of the embodiments, as shown in fig. 5, a folding buffer plate may be provided only between the two forming plates (the bottom front outer plate 10611 and the bottom rear outer plate 10612) of the bottom outer plate and the lining plates (the front horizontal lining plate forming part 2011 and the rear horizontal lining plate forming part 2012) connected thereto, because the slots (the first slots 4021 and 4022) on the two forming plates (the bottom left inner plate 10621 and the bottom right inner plate 10622) of the bottom inner plate span the connecting position of the forming plate of the bottom inner plate and the lining plate connected thereto, so that the forming plates of the bottom inner plate are cut into a shorter connecting structure, and thus the difficulty in folding is reduced.

In addition, folding cushioning plates (not shown in fig. 5) may also be provided at the junctions between the top inner panel 1051 and the front side 101 connected thereto, and the top outer panel 1052 and the rear side 102 connected thereto.

The utility model can be arranged according to the following structure for preventing the double-layer structure of the top surface from automatically turning up due to the effect of the resilience force of the turning-over part of the top outer plate 1052: as shown in fig. 3 and 5, two side edges of the top outer plate 1052 are respectively connected with an ear plate, including a left ear plate 3021 and a right ear plate 3022, as shown in fig. 2, when the top outer plate 1052 is covered and attached to the top inner plate 1051, the two ear plates are inserted into two sides of the top inner plate 1051, the left ear plate 3021 is located between the lateral lining plate 201 and the left side 103 of the box body, and the right ear plate 3022 is located between the lateral lining plate 201 and the right side 104 of the box body. When the two ear plates are inserted and positioned in the inner cavity of the box body, the two ear plates are turned outwards under the resilience effect of the turning positions, so that the two ear plates are tightly attached to the inner surface of the left side surface 103 or the right side surface 104, and the two ear plates can be better attached to the inner surface of the left side surface 103 or the right side surface 104 due to the extrusion of the left end and the right end of the transverse lining plate 201 on the two ear plates, so that a better self-locking effect after the top surface is covered is achieved.

In order to facilitate opening of the top surface, the top outer plate 1052 can be provided with a first notch 4031, and the top inner plate 1051 is provided with a second notch 4032, so that a person can conveniently exert force when turning up the top outer plate 1052 and the top inner plate 1051.
