Description

Technical Field

[0001] This utility model relates to the field of metal storage box technology, and more specifically, to a side-folding type metal storage box. Background Technology

[0002] Metal storage boxes can be used to store parts, tools, and products. Their acid and alkali resistance, as well as oil resistance, make them suitable for various environments. Foldable metal storage boxes can be folded up when not in use, saving space and floor area. This foldability significantly reduces logistics costs. Furthermore, compared to packaging that is completely disassembled into sheets, foldable metal storage boxes reduce the amount of packing material needed, saving on packaging costs.

[0003] However, to ensure sufficient mechanical strength, drawers generally do not employ a folding structure. Since drawers themselves occupy space, even if the metal storage box were folded, the overall volume would not be effectively reduced; instead, additional packaging and padding would be needed. Therefore, most metal storage boxes with drawers on the market are shipped pre-assembled, rather than folded. Furthermore, existing folding metal storage boxes also have the following drawbacks:

[0004] (a) The existing folding metal storage boxes have a relatively complex folding structure, requiring specific operating steps to unfold or fold, which increases the difficulty of use and installation, especially for users who are not familiar with such products.

[0005] (ii) The front of a metal storage box is a critical area. On the one hand, the front of a metal storage box is the most common surface, and on the other hand, important components such as locks and hinges are mostly located on the front. If the front of a metal storage box is dented, it will not only negatively affect its appearance, structural strength, and corrosion resistance, but may also damage key parts such as locks and hinges, affecting their normal function, such as making it difficult to open and close. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a side-folding metal storage box. This metal storage box achieves folding while taking into account the drawer setting, which can reduce the packaging volume of the storage box, save logistics costs, reduce packaging fillers, and lower packaging costs.
