High-strength corrugated carton with double-layer supporting structure

The utility model is applicable to the technical field of corrugated carton structures, and provides a high-strength corrugated carton with a double-layer supporting structure, which comprises a carton bottom plate, a plurality of carton side wall mechanisms and a carton top plate mechanism, and the carton side wall mechanisms are vertically and fixedly connected to the upper surfaces of four outer edges of the carton bottom plate respectively. According to the high-strength corrugated carton of the double-layer supporting structure, by arranging a plurality of bending pieces and a plurality of reinforcing strips, when the corrugated carton is actually used, firstly, the bending pieces on the inner-layer side plates of the carton side wall mechanisms of the corrugated carton are bent downwards and then inserted into the corresponding clamping grooves; at the moment, a triangular structure is formed by the multiple bent pieces and the side surfaces and the bottom face of the box body, the overall stability and
