As a preferred embodiment, the four corners of the inner wall of the carton main body are fixedly connected with lining corners, and the cross section of the inner lining corners is an "L"-shaped structure, and the four corners of the inner wall of the carton main body are fixedly connected with two As for the clamping block, one end of the lining corner is slidably engaged between two corresponding clamping blocks.

As a preferred embodiment, the bottom of the inner wall of the main body of the carton is provided with a support bar, the support bar is an "X"-shaped structure, and the four corners of the support bar are respectively fixedly connected with the inner walls of the four lining corners.

As a preferred embodiment, the four corners of the lower surface of the carton main body are wrapped and fixed with outer pad corners, and the outer wall of the carton main body is bonded with a protective layer, and the protective layer is a waterproof film.

As a preferred implementation manner, the pin shaft is located above the contact surface between the support frame and the support plate.

Compared with the prior art, the beneficial effects of the utility model are:

In the utility model, a supporting frame is fixed on the inner wall of the opening end of the carton main body, and the supporting plate connected with it can form a supporting surface at the opening end of the carton main body. When the carton cover is rotated and closed, the carton cover passes through the reinforcing plate and The support frame is in contact with the support plate, so that the support frame cooperates with the support plate to stably support the carton cover, which can prevent its excessive deformation and adversely affect its packaging effect when it is under pressure. The plates are connected so that the support plate can be rotated outward to prevent it from hindering the storage of items. Through its design, the carton has good compression resistance and provides convenience for the safe transportation of items;

In the utility model, by setting corresponding blocks at the four corners of the inner wall of the carton main body, it can be used to connect the lining corners, and under the cooperation of the support strips, the structure of the carton main body can be reinforced to prevent the corners from The main body of the carton is deformed due to bumping, which improves its safety during use.

detailed description

Below in conjunction with embodiment the utility model is described further.

The following examples are used to illustrate the utility model, but can not be used to limit the protection scope of the utility model. The conditions in the embodiment can be further adjusted according to the specific conditions, and the simple improvement of the method of the utility model under the premise of the concept of the utility model belongs to the protection scope of the utility model.

Please refer to Figures 1-3, the utility model provides a double-layer anti-extrusion packaging carton, including a carton main body 1, the left and right sides of the opening inner wall of the carton main body 1 are fixedly connected with a support frame 2, and one end of the support frame 2 passes through The provided pin shaft 7 is hinged with a support plate 3, and the inner wall of the carton cover 4 on both sides of the carton main body 1 is bonded with a reinforcement plate 5, and the outer wall of the support plate 3 and the outer wall of the reinforcement plate 5 are provided with several anti-slip grooves 8, through The anti-slip groove 8 can increase the frictional force between the support plate 3 and the reinforcing plate 5, thereby achieving an anti-slip effect.

Specifically, as shown in Figure 2, the support frame 2 and the support plate 3 are both hard cardboard, and the reinforcing plate 5 is a plastic plate. Through its design, excessive manufacturing costs can be prevented, and the carton has the characteristics of light weight. It is convenient for repeated use.
