[0032] refer to Figure 1-Figure 5 By setting a waterproof layer 12, the inner structure of the packaging carton can avoid erosion due to moisture resurgence when in use, thereby maintaining the stability of the overall structure. In addition, a hard reinforcement ring 13 is provided to increase the pressure resistance of the side wall of the carton, which will not bend easily and maintain the aesthetic appearance of the carton. The support mechanism 2 can further increase the pressure resistance of the carton and reinforce it from the top, bottom and side walls in all directions. At the same time, under the conduction and support of the support rod 22, the pressure applied to the carton from the top by the outside world can be transmitted to the support at the bottom of the carton, thereby ensuring the integrity of the main mechanism 1.

[0033] refer to Figure 1-Figure 5In this embodiment, a waterproof layer 12 is provided so that the bottom of the paper layer 11 will not be affected by water. A cross 24 is provided so that the paper top cover 16 will not be deformed when squeezed. In addition, a lifting piece 17 and a lifting piece 2 18 are provided, and the two can be used in combination. Therefore, when carrying the carton, the paper layer 11 and the paper layer 2 14 are not easily torn and deformed.

[0034] Working principle: Reference Figure 1-Figure 5 When the utility model is in use, if the side wall of the paper layer 11 is squeezed, the pressure will be borne by the support rod 22 and the hard reinforcing ring 13, and at the same time, the hard reinforcing ring 13 can effectively prevent the surface of the paper layer 11 from having obvious depressions and creases, thereby improving the pressure resistance of the side wall of the packaging carton. When pressure is applied to the top of the carton, the pressure will be transmitted to the support rod 22 by the top frame 23 and the cross 24, and finally transmitted to the support at the bottom of the carton through the bottom frame 21, thereby improving the pressure resistance of the top of the packaging carton. At the same time, the cross 24 can prevent the paper top cover 16 from denting toward its center when it is squeezed, thereby improving the pressure resistance of the paper top cover 16. The integrity of the top cover 16 is guaranteed. In addition, when the carton is in use and water accumulates at the bottom thereof, the plastic pad 15 can be used to ensure that the paper layer 11 does not absorb water, and the main body 1 does not deform or even damage. At the same time, in a water-accumulating environment, the moisture absorbed by the paper layer 11 does not spread to the paper layer 2 14. Under the action of the waterproof layer 12, the items inside the carton are prevented from being affected by moisture as much as possible. If the carton needs to be moved, the lifting tab 1 17 and the lifting tab 2 18 can be half-gripped at the same time, and the paper layer 11 and the paper layer 2 14 can be effectively prevented from being torn. In summary, the packaging carton has strong pressure resistance.
