The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please refer to the appendix carefully. Figures 1-6 A reinforced rotomolded box includes a box body 1. The side walls and bottom of the box body 1 are provided with a reinforcing structure, which includes reinforcing ribs 5 and a reinforcing bottom plate. The box body 1 is provided with a removable cushioning component inside. The bottom and top of the box body 1 are provided with mutually cooperating stacking modules. The reinforcing ribs 5 and the reinforcing bottom plate improve the impact resistance of the box body 1. The cushioning component improves the stability of the items contained in the box body 1. The stacking modules improve the stacking stability of the box body 1, thereby increasing the service life of the box body 1.

[0028] In this utility model, the reinforcing ribs 5 are evenly arranged on the side wall of the box body 1, and are recessed inward on the side wall of the box body 1. The reinforcing ribs 5 are provided with inclined walls, and the wall thickness of the reinforcing ribs 5 increases from top to bottom. The reinforcing bottom plate is a honeycomb rib 9 provided at the bottom of the box body 1. Through the gradual increase in the wall thickness of the reinforcing ribs 5 and the honeycomb rib 9 at the bottom of the box body 1, the overall load-bearing capacity and impact resistance of the box body 1 are further improved.

[0029] In this utility model, the buffer is a protective plate 8, which is placed inside the box 1 and contacts the side wall, reinforcing ribs 5 and honeycomb ribs 9 to ensure the stability of the object's movement.

[0030] In this utility model, the stacking module includes a stacking slot 6 and a stacking block 7. The stacking block 7 cooperates with the stacking slot 6. The stacking block 7 is set on the top of the box 1, and the stacking slot 6 is set on the bottom of the box 1. This improves the stability of the stacking of the box 1 and thus increases the stacking height.

[0031] In this utility model, the side end of the box body 1 is symmetrically provided with rollers 4 for movement; the side end of the box body 1 is provided with one or more pull rings 3; the box body 1 is provided with a lock 2, which is used to fix the lid of the box body 1.

[0033] The implementation principle of this utility model of a reinforced rotational molding box is as follows:

[0034] 1. Improved load-bearing capacity and enhanced impact resistance: The thickness of the bottom honeycomb ribs 9 and the side wall reinforcing ribs 5 of the box body 1 gradually increases, thereby improving the load-bearing capacity and impact resistance of a single box;

[0035] 2. Improve stacking stability: Through stacking blocks 7 and stacking slots 6, it is possible to sequentially correspond to boxes 1 of the same specifications, or to stack other boxes 1 (medium boxes, small boxes) on top of box 1 (large box).

[0036] 3. Movement stability: The rollers 4 facilitate the movement of the box 1, and the protective plate 8, which is set to buffer the objects, can buffer and protect the moving objects, thereby improving stability.
