[0002] Turnover boxes are widely used in the manufacturing industry, mainly for holding parts and materials, and can participate in multiple stages of logistics such as transportation, distribution, storage, and processing.
[0003] Patent CN220997244U discloses a turnover box, including a base plate, a mounting ring above the base plate, side plates symmetrically hinged below the mounting ring, and double-folded plates symmetrically hinged to the mounting ring and perpendicular to the side plates. A splicing limiting part is provided between the double-folded plates, which limits the maximum unfolding stroke of the double-folded plates to a vertical state. When the double-folded plates are subjected to the unfolding force to a vertical state, the double-folded plates are automatically limited; when the double-folded plates are subjected to a certain force to fold, the double-folded plates are released from the limiting part and fold inward. This turnover box can simplify the loading and unloading process and make folding or unfolding more convenient.
[0004] The structure described above lacks a moving mechanism at the bottom, making it inconvenient to temporarily pull heavy items from the container on the ground, resulting in low dragging efficiency. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a foldable turnover box, which has the following beneficial effects:
[0017] When the structure is not in use, the frame is pulled out, and then the first side plate is folded around the fourth hinge assembly at its top. The frame is further pressed down, and the joint between the first baffle and the second baffle is pushed. Through the action of the first hinge assembly, the first baffle and the second baffle can be folded inward between the bottom plate and the frame, thereby lowering the position of the frame. This makes it convenient to temporarily fold the structure so that it can be carried when not in use.
[0018] During placement, multiple bases of this structure contact the ground. When it is necessary to pull the structure on the ground, a pulling force is provided to the shell. When the pulling force is greater than the friction between the positioning block and the base plate, the shell can be disassembled at the lower end of the base plate, allowing the bottom wheels to contact the ground. With the multiple bottom wheels, the structure can be easily pulled on the ground with high dragging efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-8 The folding turnover box of this utility model includes a base plate 1 and a frame 8. Two first side plates 13 are symmetrically arranged vertically between the base plate 1 and the frame 8, and two second side plates are symmetrically arranged horizontally between the base plate 1 and the frame 8. The bottom end of the base plate 1 is provided with multiple moving components, each of which includes a bottom wheel 2 and a housing 4.
