[0001] The invention relates to the technical field of household appliances, in particular to a foldable storage box. Background Art

[0002] At present, among household appliances, storage boxes are being used by more and more families to store clothes or other sundries in the family. Existing storage boxes are also designed with a folding function to facilitate folding and storage or carrying. Since the storage box has a folding function, the side panels of the storage box need to be detachably connected, and the connection between the side panels is required to be firm; however, the connection structure between the side panels of the existing storage box is not firm, which reduces the use performance of the storage box. Summary of the invention

[0003] The purpose of the present invention is to provide a foldable storage box capable of improving the connection strength between side panels.

[0004] In order to achieve the above object, the present invention provides a foldable storage box, comprising:

[0005] A bottom plate, along the edge of which a first connecting plate, a second connecting plate and a third connecting plate are fixed in sequence; the first connecting plate is arranged opposite to the third connecting plate;

[0006] A first side plate, a second side plate and a third side plate hinged to the first connecting plate, the second connecting plate and the third connecting plate in a one-to-one correspondence;

[0007] a fourth side panel, the fourth side panel being arranged opposite to the second side panel and being hinged to the first side panel and the third side panel respectively;

[0008] In the storage state, the first side plate, the second side plate, the third side plate and the fourth side plate are connected to each other to form a storage cavity with an opening; a cover plate is provided on the opening;

[0009] The first side panel has first protrusions and first slots fixedly disposed on opposite end edges, respectively, and the third side panel has the same structure as the first side panel; the second side panel has second protrusions fixedly disposed on opposite end edges for engaging with the first slots; the fourth side panel has second slots fixedly disposed on opposite end edges for engaging with the first protrusions; the first slot and the second protrusion have matching first limiting structures; the first protrusion and the second slot have matching second limiting structures.

[0010] Among them, in the folded state, the first side panel and the third side panel are both attached to the upper surface of the bottom panel, and the third side panel is attached to the first side panel and the third side panel; the cover panel covers the third side panel; and the fourth side panel is attached to the lower surface of the bottom panel.

[0011] Compared with the prior art, the folding storage box of the embodiment of the present invention has the following beneficial effects: by hingedly connecting the first side panel, the second side panel and the third side panel to the first connecting panel, the second connecting panel and the third connecting panel respectively, and hingedly connecting the fourth side panel to the first side panel and the third side panel respectively; the first side panel, the second side panel, the third side panel and the fourth side panel can be conveniently rotated relative to the bottom panel to realize the folding function. In the sequential connection between the first side panel, the second side panel, the third side panel and the fourth side panel, the second side panel is respectively engaged with the first side panel and the third side panel through the corresponding first slot and the second protrusion, and the fourth side panel is respectively engaged with the first side panel and the third side panel through the corresponding second slot and the first protrusion; and the first slot and the second protrusion have a matched first limiting structure; the first protrusion and the second slot have a matched second limiting structure; the first limiting structure is used to limit the second protrusion from coming out of the first slot; the second limiting structure is used to limit the first protrusion from coming out of the second slot, thereby improving the firmness of the connection of the side panels of the storage box.

[0012] Furthermore, a limiting plate is fixedly provided on the second side panel, and the limiting plate is fixedly connected to the second protrusion; in the storage state, the limiting plate is parallel to the bottom panel. The limiting plate can limit the vertical movement of the first side panel and the third side panel relative to the second side panel, thereby improving the firmness of the connection between the second side panel and the first side panel and the third side panel. In the storage state, the limiting plate is parallel to the bottom panel, that is, the limiting plate is perpendicular to the second side panel, thereby improving the strength of the second side panel.

[0013] Specifically, the bottom plate, the first side plate, the second side plate, the third side plate and the fourth side plate may be provided with reinforcing plates to improve their inherent strength, thereby ultimately improving the strength of the storage box.

[0014] Furthermore, the fourth side plate is provided with a through hole, and a door panel is hinged in the through hole; the size of the through hole matches the size of the door panel. The through hole and the door panel are provided to facilitate users to take or store corresponding items.

[0015] Furthermore, the first limiting structure includes a first clamping hole provided on the inner wall of the first clamping slot and a first protrusion fixedly provided on the second protrusion; when the first clamping slot is clamped with the second protrusion, the first protrusion is clamped in the first clamping hole. By providing the first protrusion and the first clamping hole to cooperate with each other, the second protrusion can be more firmly clamped in the first clamping slot, thereby preventing the second protrusion from falling off from the first clamping slot and improving the firmness of the connection.

[0016] Furthermore, the second limiting structure includes a second protrusion fixedly arranged on the inner wall of the second slot and a second clamping hole provided on the first protrusion; when the second slot is clamped with the first protrusion, the second protrusion is clamped in the second clamping hole. The second protrusion and the second clamping hole cooperate with each other so that the first protrusion can be more firmly clamped in the second slot, thereby preventing the first protrusion from falling off from the second slot and improving the firmness of the connection.

[0017] Furthermore, the bottom plate, the first side plate, the second side plate, the third side plate, the fourth side plate, the first connecting plate, the second connecting plate, the third connecting plate, and the cover plate are all injection molded parts. Injection molding can improve product performance, facilitate production, and improve production efficiency.

[0018] Furthermore, a supporting block is provided on the edge of the fourth side plate close to the bottom plate; in the storage state, the supporting block abuts against the bottom edge of the bottom plate. Providing the supporting block can improve the bearing capacity of the bottom plate. During the rotation of the fourth side plate, the supporting block will squeeze the edge of the bottom plate. After the edge of the bottom plate undergoes corresponding elastic deformation, the supporting block enters the ground of the bottom plate and abuts against the bottom surface. Specifically, the material of the bottom plate is selected to be a plastic product, which can more easily undergo elastic deformation, so that the supporting block can enter the bottom surface of the bottom plate better and more effortlessly.

[0019] Furthermore, the bottom plate, the first connecting plate, the second connecting plate and the third connecting plate are integrally formed parts, which is easy to produce, increases production efficiency and can improve the firmness of the connection.

[0020] Furthermore, the lower ends of the first connecting plate, the second connecting plate and the third connecting plate are all located below the bottom plate; the bottom plate is connected with the first connecting plate, the second connecting plate and the third connecting plate to form a first groove for placing the fourth side plate. The first groove can easily accommodate the fourth side plate to prevent the bottom plate from squeezing the fourth side plate when the storage box is placed in a folded state.

[0021] Specifically, the lower ends of the first connecting plate, the second connecting plate and the third connecting plate are all located on the same predetermined plane, so that the storage box can be placed horizontally and the stability is improved.

[0022] Furthermore, the cover plate is provided with a second groove for the opening to be inserted into, thereby improving the firmness of the connection between the cover plate and the opening.

[0023] Furthermore, the number of the first protrusions and the number of the second slots are both one-to-one corresponding to each other, and the plurality of first protrusions are spaced and distributed along the edges of the first side plate and the third side plate, respectively, so as to improve the strength of the connection.

[0024] Furthermore, the height of the first connecting plate and the third connecting plate is less than the height of the second connecting plate; the first side plate, the second side plate and the third side plate are hinged to the top of the first connecting plate, the top of the second connecting plate and the top of the third connecting plate respectively. This height setting can facilitate the first side plate and the third side plate to be better attached to the bottom plate, and the second side plate to be better attached to the first side plate and the third side plate. This design is reasonable, compact and folded, and the volume of the storage box after folding is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
