The plurality of second longitudinal ribs 222 respectively correspond to the plurality of clamping grooves 21, that is, the plurality of second longitudinal ribs 222 respectively correspond to the plurality of first ribs 33 on the top cover 3 (specifically, the plurality of second longitudinal ribs 222 on the first movable plate 2A respectively align with the plurality of first transverse ribs 331 on the top cover 3, and the plurality of second longitudinal ribs 222 on the second movable plate 2B respectively align with the plurality of first longitudinal ribs 332 on the top cover 3), so that the bearing force borne by the top cover 3 can be better transferred to the base 1 through the respective movable plates 2, and the bearing force of the folding storage box is further improved.

As shown in fig. 5, a stop block (not numbered in the figure) is provided on the inner wall of the top cover 3, that is, the inner wall of the top cover is close to the corner and a circular protrusion is provided on the inner side of the turnup on the long side of the inner wall of the top cover, so that the stop block blocks the movable plate 2 from being turned inwards when the folding type storage box is in the storage state. The shape of the stopper is not limited to a circular shape, and may be a structure capable of mainly blocking the movable plate.

As shown in fig. 16, an embodiment of the present utility model further provides a folding bin assembly including a plurality of the folding bins described above. Specifically, the folding bin assembly includes one or more of the rectangular parallelepiped folding bins 101 described above and/or one or more of the square folding bins 102 described above. The folding storage boxes with the same size can be stacked with each other; meanwhile, the length of the rectangular parallelepiped-shaped folding type storage case 101 is twice the length of the square-shaped folding type storage case 102, so that two square-shaped folding type storage cases 102 can be stacked on one rectangular-shaped folding type storage case 101 right and left. The folding type storage boxes with the two sizes can be freely combined and stacked.

According to the folding storage box provided by the embodiment of the utility model, the connecting pieces 4 are arranged, the movable plates 2 are respectively connected with the side plates 12 in a rotating way through the connecting pieces 4, the first end 40A of each connecting piece 4 is hinged with the corresponding side plate 12, the second end 40B of each connecting piece 4 is hinged with the corresponding movable plate 2, namely the connecting pieces 4 form a structure with hinged two ends, so that when the movable plates 2 are folded downwards, the two opposite movable plates 2 can be stacked up and down, and the folded volume of the folding storage box is further reduced; moreover, when the two opposite movable plates 2 are folded, the sequence is not required to be distinguished (namely, the two movable plates can be folded in any sequence without purposely folding which movable plate 2 first), so that the use is convenient. Meanwhile, the movable plate 2 is rotationally connected with the side plate 12 through the connecting piece 4, the height of the hinge position between the connecting piece 4 and the side plate 12 can be not considered, the structure is simpler, the movable plate 2 can rotate more smoothly, and the movable plate is convenient to use.

The foregoing is merely illustrative embodiments of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present utility model, and the utility model should be covered. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
