Referring to fig. 1 and 2, a medium corrugated cardboard box includes a box body 1 and an inner frame 2, the inner frame 2 is disposed on an inner surface of a bottom end of the box body 1 in a vertical direction, and a top end of the inner frame 2 is contactable with a top end of the box body 1, so that when an object is pressed against the box body 1, the inner frame 2 helps to share pressure of a side surface of the box body 1, increasing compressive strength of the box body 1, so as to avoid deformation of a middle weak portion on the side surface of the box body 1.

Referring to fig. 2, the inner frame 2 includes a plurality of corrugated columns 21 disposed on two opposite inner side surfaces of the box body 1, each of the corrugated columns 21 is formed by two corrugated boards 211, and one ends of the two corrugated boards 211 forming the corrugated columns 21, which are close to each other, are inclined toward a direction away from the inner side wall of the box body 1, so that a triangular region can be formed between the corrugated columns 21 and the inner side wall of the box body 1. Integrally formed has connecting paperboard 22 between two adjacent stupefied post 21, connecting paperboard 22 and the contact of box 1 inside wall, connecting paperboard 22 one-to-one on two relative inside walls of box 1, and corresponding two connecting paperboard 22's bottom integrated into one piece have supporting paperboard 23, and supporting paperboard 23 sets up on the internal surface of box 1 bottom to leave the space between two adjacent supporting paperboard 23. Referring to fig. 3, after the inner frame 2 is taken out, the two corrugated boards 211 forming each corrugated column 21 are unfolded, and the gap between the two adjacent supporting boards 23 is enlarged, so that the inner frame 2 is conveniently unfolded into a piece of paper, and the inner frame 2 is stored.

Referring to fig. 1, a reinforcing paperboard 3 is detachably connected between two corrugated boards 211 forming a corrugated column 21, the reinforcing paperboard 3 is arranged in the vertical direction, and a triangular prism is formed between the reinforcing paperboard 3 and the two corrugated boards 211, so that the reinforcing paperboard 3 and the two corrugated boards 211 help to play a certain buffering role when the carton falls in transportation. Referring to fig. 2, a desiccant bag 4 is arranged in the triangular prism, so that the desiccant bag 4 absorbs moisture in the box body 1, and the compression strength of the corrugated carton is prevented from being affected after the corrugated carton is wetted. Both ends of the reinforcing cardboard 3 in the horizontal direction correspond to the two corrugated cardboards 211 one to one, and the connection structure of the end of the reinforcing cardboard 3 and the corrugated cardboard 211 is equal, as described below by taking the connection structure of one end of the reinforcing cardboard 3 and the corrugated cardboard 211 as an example:

a first extension plate 31 is integrally formed at one end of the reinforced paperboard 3, and a connecting plate 32 is integrally formed at one end of the first extension plate 31 far away from the reinforced paperboard 3; the corrugated board 211 is provided with two abdicating holes 2111, the two abdicating holes 2111 are distributed along the horizontal direction, one end of the connecting plate 32 far away from the reinforcing board 3 passes through one of the abdicating holes 2111 to extend into the box body 1, and passes back to one side of the corrugated board 211 close to the inner side wall of the box body 1 from the other abdicating hole 2111; the reinforcing paperboard 3 can be taken down by pulling out the connecting plate 32 from the yielding hole 2111, and the detachable connection between the reinforcing paperboard 3 and the corrugated board 211 is realized.

Referring to fig. 2, the stupefied column 21 at the end of the inner side wall of the box body 1 abuts against the adjacent inner side wall of the box body 1, which helps to fix the position of the inner frame 2, so as to avoid the inner frame 2 from shaking in the box body 1.

Referring to fig. 5, the box body 1 comprises two layers of sheet paper 11, and vertical corrugated paper 12 and horizontal corrugated paper 13 which are arranged between the two layers of sheet paper 11, wherein the corrugations on the vertical corrugated paper 12 are arranged in the vertical direction so as to increase the compressive strength of the box body 1 in the vertical direction; the corrugations of the transverse corrugated paper 13 are arranged in the horizontal direction so as to increase the compression strength of the box body 1 in the horizontal direction. The vertical corrugated paper 12 is located on one side of the horizontal corrugated paper 13 close to the inner surrounding frame 2, and the partition paper 14 is connected between the vertical corrugated paper 12 and the horizontal corrugated paper 13, so that when the inner layer and the outer layer of the board paper 11 of the box body 1 are extruded, the partition paper 14 helps to relieve the interaction force of the corrugation on the horizontal corrugated paper 13 and the corrugation on the vertical corrugated paper 12, and further helps to avoid the compression strength of the box body 1 caused by deformation after the horizontal corrugated paper 13 and the vertical corrugated paper 12 are extruded.

The implementation principle of the medium corrugated case in the embodiment of the application is as follows: when the box body 1 is pressed with heavy objects, the inner surrounding frame 2 in the box body 1 and the reinforcing paperboard 3 in the prismatic column 21 forming the inner surrounding frame 2 are convenient for adding the compressive strength of the side surface of the cavity box body 1. If the box body 1 falls off in the conveying process, the triangular prism formed by the prismatic columns 21 and the reinforcing paper boards 3 can buffer articles in the box body 1 to a certain extent. When the inner frame 2 needs to be disassembled, the inner frame 2 is taken out from the box body 1, and the corrugated board 211 constituting each corrugated column 21 is unfolded, so that the inner frame 2 can be unfolded to be a piece of paper, so as to store the inner frame 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
