The present disclosure relates to the field of item storage equipment, and in particular, to a collapsible storage box.

BACKGROUND TECHNOLOGY

Storage boxes are commonly known as sorting chests, containers, sorting boxes, and containing boxes. The storage boxes may be made of a variety of materials, usually including plastics, fabrics, paper, metals, wood, etc.

In order to improve the applicability of storage boxes, certain improvements have been made to the storage boxes in the prior art such that various storage boxes are obtained with adjustable spatial storage sizes. In order to realize variable sizes, storage boxes of this type share a common point that areas are changed by sleeve connection and folding of panels on their sides. However, existing storage boxes of this type cannot be collapsible and thus may occupy large storage space when they are not used.

In addition, it needs to be noted in the manufacturing process that: the sixth bottom corrugated retractable plate 2-41 is on an outer side and the seventh bottom corrugated retractable plate 2-42 is on an inner side, with a relative height difference therebetween. The first side retractable plate assembly 1-1 and the second side retractable plate assembly 1-2 are sleeved with each other such that there is obviously a relative height difference therebetween.

When folding, since the extension direction is perpendicular to the rotation direction, limiting is achieved. Therefore, there is no relative displacement between two corresponding rotating plates in the folding process, and the stability of the folding structure is greatly improved.

Embodiment 7.1

As shown in FIGS. 21-24, this embodiment discloses a collapsible storage box of another folding structure for storage and transportation in a non-use state: it includes a box body having a containing space that is formed by joining four side retractable assemblies and at least one bottom retractable assembly.

Each side retractable assembly is formed by two first side retractable plate assemblies 1-1 slidably sleeved with each other.

A side edge of the bottom retractable assembly is hinged with a lower portion of one side retractable assembly.

Two opposite side retractable assemblies of the four side retractable assemblies are combined to form flipping unit 3-21, and the other two opposite side retractable assemblies are combined to form infolding unit 3-22.

The flipping unit 3-21 further includes flipping cross beam 3-211 disposed above the side retractable assembly, and an upper portion of the side retractable assembly is rotatably connected to the flipping cross beam 3-211. Two ends of the flipping cross beam 3-211 are fixedly connected to the side retractable assemblies on the two corresponding sides within the infolding unit 3-22.

Moreover, in this embodiment, it further needs to be noted that in order to guarantee that the upper infolding subunit 3-221 and the lower infolding subunit 3-222 can be folded while sliding normally, the middle breakage positions of the vertical guide rails between them need to be foldable to achieve the above function.

Embodiment 7.2

As shown in FIGS. 25-28, another collapsible storage box solution is disclosed in another similar embodiment. In this solution, retraction and extension can be realized in length, width, and height directions, with specific differences from the above embodiment as follows:

Embodiment 8.1

As shown in FIGS. 29-32, this embodiment discloses a collapsible storage box of another folding structure for storage and transportation in a non-use state: it includes a box body having a containing space that is formed by joining four side retractable assemblies and at least one bottom retractable assembly.

Each side retractable assembly includes first side retractable plate assembly 1-1 formed by two movable panels slidably sleeved with each other.

A side edge of the bottom retractable assembly is hinged with a lower portion of one side retractable assembly.

Adjacent two side retractable assemblies of the four side retractable assemblies are combined in pair to form two folding units 3-31; transverse folding avoidance plate 3-311 configured to avoid thicknesses of the side retractable assemblies after being folded is disposed between the two side retractable assemblies inside each folding unit 3-31; and one side edge of the transverse folding avoidance plate 3-311 is fixedly connected to one side retractable assembly, while the other side edge is hinged with the other side retractable assembly.

Embodiment 8.2

As shown in FIGS. 33-36, another collapsible storage box solution is disclosed in another similar embodiment. In this solution, retraction and extension can be realized in length, width, and height directions, with specific differences from the above embodiment as follows:

Embodiment 9

With reference to FIG. 37, the difference from Embodiment 8 is as follows: the bottom retractable assembly is designed into a two-side flipping structure in this embodiment to facilitate opening and folding.

In the present disclosure, the advantages of the hinge assembly (4) are as follows. The first slide rail (4-61) and the first slider (4-62), as well as the second slide rail (4-71), and the second slider (4-72), form a sliding structure. In both folded and unfolded states, the first outer rotating plate (4-1) and the second outer rotating plate (4-2), as well as the first inner rotating plate (4-4) and the second inner rotating plate (4-5), can be freely slidably retracted and extended. The first slide rail (4-61) and the second slide rail (4-71) play a limiting role. The displacement that may occur during the folding process between the inner and outer plates is adjusted through the arc-shaped elastic connector (4-3) to ensure that their folding direction is always perpendicular to the sliding direction. The design greatly improves the stability of the folding structure between the side wall and the bottom plate, as well as between the side walls. In addition, the edge positions of the inner and outer plates between the side wall and the bottom plate, as well as between the side walls, can be aligned at any time without interference in the folded or unfolded state. Thus, each side wall and the bottom plate can be smoothly pushed and pulled to achieve retraction and extension in the folded or unfolded state. Meanwhile, in order to smoothly achieve the purpose of retraction and extension, when the edge positions of the inner and outer plates between each side wall and the bottom plate, as well as between the side walls, are hinged, the best connection method is to provide a hinge structure between the mutually close inner plates, as well as between the mutually close outer plates.

In the description of the present disclosure, the term “hinge” is only intended to describe the connection relationship between components. Therefore, features defined by “hinge” can explicitly or implicitly include various implementations such as fold hinge, butt hinge, and link hinge.

Moreover, it further needs to be noted that the structure with a wavy cross section is illustrated in the drawings corresponding to the corrugated retractable plates mentioned in the embodiments, and it would be easy for those skilled in the art to conceive of modifying the wavy shape to square, V-shape, trapezoid, or a combination thereof, which should all be included within the protection scope of the present disclosure.

The above embodiments are preferred embodiments of the present disclosure. However, the embodiments of the present disclosure are not limited to the above embodiments, and any other changes, modifications, replacements, combinations, and simplifications made without departing from the spirit and principles of the present disclosure should be equivalent substitutions and shall be included within the protection scope of the present disclosure. In addition, for various retractable structures adopted in the present disclosure, those skilled in the art should be able to understand that suitable dampings should be disposed therebetween so that two retractable assemblies can slide toward each other and a certain frictional force can be maintained to form a locking effect, thereby maintaining a certain spatial shape and size of the box body.
