Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and in particular to a foldable storage box and an expandable storage cabinet. Background Art

[0002] In order to facilitate storage, classification and transportation, we often need to use storage boxes to hold various goods. However, there are some problems with traditional storage boxes, the most prominent of which is that the empty storage box still occupies a lot of space when not in use, which brings great inconvenience to storage and transportation. Traditional storage boxes are usually made of rigid materials such as plastic, wood or metal. These materials have a fixed volume, so the storage boxes made of them still occupy a certain amount of space when not in use. In addition, the structure of traditional storage boxes is also relatively simple, and no consideration is given to how to minimize the space occupied when idle.

[0003] In order to solve the above problems, there are several foldable storage boxes on the market, which can be conveniently stored after being folded when not in use, thereby also reducing the volume and space occupied.

[0004] The defects of known foldable storage boxes generally include: poor design of the folding structure, poor connection between components, unstable structure when using the storage box, not allowing the storage of heavy items, and not allowing multiple foldable storage boxes to be stacked, etc. For example, the patent document "Folding Box and Method of Use Thereof" with US application number 20230257160 discloses a folding box that is easy to fold and unfold, and the folding box can be easily stacked. The invention comprises a fixed frame and folding side walls hinged on the frame, which can be simply stacked through stacking holes. In addition to the hinges, the folding box structure only has a buckle fixation at the intersection of the four side walls of the box body. There is a situation that the folding box is unstable when the objects placed in the box may collide with the box body. After the folding boxes are stacked through the stacking holes, except for the top folding box, other folding boxes can no longer be used to take and place objects. If you want to take or place, you have to separate the stacked folding boxes, which is very inconvenient. Similarly, the patent document "Folding Storage Box" with US application number 20070095825 also discloses a foldable storage box, which also has the problem of unstable placement of objects and inability to stack multiple items. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technologies and provide a foldable storage box and an expandable storage cabinet.

[0006] A foldable storage box, comprising an upper frame, a bottom plate, two long side walls arranged along the length direction of the upper frame and two narrow side walls arranged along the width direction of the upper frame, each long side wall comprising a long side wall upper plate and a long side wall lower plate which are rotatably connected, the top end of the long side wall upper plate is rotatably connected to the upper frame, the bottom end of the long side wall lower plate is rotatably connected to the bottom plate, the top end of each narrow side wall is rotatably connected to a width direction portion of the upper frame, and a first mounting buckle group which can be opened and closed is provided between the bottom end of the narrow side wall and the bottom plate;

The top end of the upper plate of the long side wall and the bottom end of the lower plate of the long side wall are provided with a rotating shaft portion that cooperates with the card slots on the first rotating connecting buckle and the second rotating connecting buckle.

[0013] Furthermore, at the bottom end of the long side wall upper plate, at least one first hinge is provided, and at least two second hinges are provided for the long side wall lower plate. The long side wall upper plate and the long side wall lower plate are hinged to each other through the first hinge and the second hinge. The long side wall can be folded into the storage box through the first hinge and the second hinge.

[0014] Furthermore, the long side wall and the narrow side wall have a certain elasticity and can bend to a certain extent under the action of external force during installation;

[0015] The width of the bottom plate is greater than the height of the long side walls, so that the two long side walls can be laid flat on the bottom plate after being folded;

[0016] The bottom plate is located on the inner side of the narrow side wall and is provided with a limiting protrusion for limiting the narrow side wall.

[0017] Furthermore, a handle hole is provided at the upper end of the narrow side wall for the user to reach out and take the storage box.
