[0027] likeFigure 1 , Figure 2 and Figure 4 As shown in the figure, this embodiment provides a multi-layered reinforcement structure to enhance the load-bearing capacity of the bottom of a cardboard box. The structure includes a cardboard box 1, with a reinforcement component 2 connected to the lower end of the box 1. The reinforcement component 2 includes, from top to bottom, a corrugated cardboard layer 23, a kraft paper layer 22, and a bottom plate 21 located at the lower end of the cardboard box 1. Reinforcing frames 25 and reinforcing ribs 26 are inserted into the middle and four corners of the bottom plate 21, the kraft paper layer 22, and the corrugated cardboard layer 23. The bottom plate 21 and the kraft paper layer 22, and the kraft paper layer 22 and the corrugated cardboard layer 23 are bonded together by an adhesive layer 24 made of white glue. The reinforcing frames 25 are embedded in the middle of the bottom plate 21, the kraft paper layer 22, and the corrugated cardboard layer 23, and are arranged in a cross shape. The reinforcing frames 25 and the reinforcing ribs 26 are made of high-strength polyester fiber.

[0028] The kraft paper layer 22 can improve the wear resistance and load-bearing capacity of the carton 1. The corrugated cardboard layer 23 can be set as a three-layer corrugated cardboard structure. The load-bearing capacity of the three-layer corrugated cardboard structure is about 80kg-300kg. The reinforcing frame 25 and reinforcing rib 26 can effectively improve the deformation resistance and load-bearing capacity of the bottom of the carton 1. The reinforcing frame 25 is set as a cross shape, which can effectively distribute the pressure inside the carton 1 and increase the pressure resistance of the bottom of the carton 1. The bottom plate 21, kraft paper layer 22 and corrugated cardboard layer 23 are firmly glued together by the adhesive layer 24 to ensure that the carton 1 will not be damaged due to poor adhesion during transportation.

[0029] like Figures 1-3 As shown, the outer wall of the carton 1 is provided with a protective component 3. The protective component 3 includes a base 31 that is wrapped around the outer wall of the base plate 21, the kraft paper layer 22, and the corrugated cardboard layer 23. The lower outer wall of the base 31 is provided with four sets of symmetrical support seats 32. The support seats 32 are set in a triangular prism shape. The four corners of the carton 1 are wrapped with edge protectors 33. The edge protectors 33 are set in an L shape. A wooden frame 34 is fixed between the edge protectors 33 and the edge protectors 33. The wooden frame 34 is attached to the outer wall of the carton 1. A waterproof layer 4 is fixed at the lower end of the base 31. The waterproof layer 4 is made of polyethylene. The lower end of the waterproof layer 4 is provided with rubber particles 5. The lower ends of the support seats 32 and the lower ends of the rubber particles 5 are on the same horizontal plane.

[0030] The edge protector 33 protects the corners of the carton 1. The wooden frame 34 not only prevents damage to the outer wall of the carton 1 from direct impact during transportation, but also provides some load-bearing capacity when the carton 1 is fully loaded, preventing damage. The support base 32 increases the contact area between the bottom of the carton 1 and the ground. Furthermore, when objects inside the carton 1 rest against its upper part, the support base 32 disperses the force on the carton 1, reducing the pressure on it. This increases the service life of the cardboard box 1. The waterproof layer 4 is fixed to the lower end of the base 31 by coating, hot pressing or bonding. Polyethylene is a thermoplastic with good waterproof performance and chemical stability. It is not easily soluble in water. The waterproof layer 4 can effectively prevent water from penetrating into the inside of the cardboard box 1, protect the contents from the influence of ground moisture, and ensure that the bottom of the cardboard box 1 will not soften. This avoids the phenomenon that the bottom of the cardboard box 1 becomes soft and cannot be picked up or moved after being placed on the ground for a long time. The setting of rubber particles 5 increases the friction between the device and the ground, so that the device can be placed stably on the ground.

[0031] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
