A buffer layer is fixedly connected inside the support layer inside the cavity;

[0006] The support layer includes a first U-shaped frame and a second U-shaped frame. The first U-shaped frame and the second U-shaped frame are fixedly connected. There are multiple first U-shaped frames and second U-shaped frames, and multiple first U-shaped frames and second U-shaped frames are staggered and distributed inside the cavity.

[0007] As a preferred implementation method, a foldable box cover is connected to the top of the box body. One end of the box cover is fixedly connected with a buckle. A card slot adapted to the buckle is arranged at the upper end of the front surface of the box body.

[0008] As a preferred implementation method, seal flaps that can be folded are connected to both sides of the opening at the top of the box body.

[0009] As a preferred implementation method, the protective layer includes a kraft paper layer and a carbon fiber woven layer that are adhesively bonded to each other.

[0010] As a preferred implementation method, the buffer layer includes a polyurethane foam layer and a rubber layer that are adhesively bonded to each other.

[0011] As a preferred implementation method, support blocks are fixedly connected to the four corners of the inner bottom wall of the box body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This carton with high support can strengthen and support the bottom and four sides of the box body by arranging a support layer in the sandwich layer of the box body. The first U-shaped frame and the second U-shaped frame can improve the support strength of the side wall of the box body, making the carton not easily deformed and damaged when being extruded by external forces. Thus, the probability of damage to the items inside the carton can be reduced, and the safety can be improved.

[0014] This carton with high support, by arranging a protective layer, both the kraft paper layer and the carbon fiber woven layer have good toughness and impact resistance and are not easily damaged when being impacted by external forces. And the kraft paper layer has certain waterproof performance, which can enhance the protection effect on the box body and reduce the probability of the carton being damaged. By arranging a buffer layer, both the polyurethane foam layer and the rubber layer have good elasticity and resilience performance. When being impacted by external forces, they are prone to undergo certain elastic deformation to buffer and reduce the impact force.
