Description

Technical Field

[0001] This utility model relates to the field of storage box technology, and in particular to a foldable storage box. Background Technology

[0002] Storage boxes, as a common household product, can provide stable storage space for many odds and ends in the room, making it convenient for users to organize and store various odds and ends. When not in use, the storage boxes can also be folded up and stored, thereby reducing the storage space occupied by the storage boxes themselves.

[0003] Existing storage boxes have flaws in their folding mechanism. The folding structure is too complex, which not only leads to high production costs and low strength, but also makes the folding process difficult. The opening design is also too simple, making it difficult to quickly access items in different situations. Utility Model Content

[0004] The technical problem this utility model aims to solve is: how to provide a new folding structure and connection structure for a storage box. To solve the above technical problem, this utility model provides a folding storage box, including a bottom plate and multiple side panels. The bottom plate and the multiple side panels are joined together to form a storage box. The bottom of each side panel is rotatably connected to the bottom plate, and two adjacent side panels are rotatably connected. The bottom plate is provided with a receiving groove for accommodating the multiple side panels after folding.

[0005] At least one of the side panels includes a door frame, a door panel is disposed inside the door frame, the door panel is slidably connected to the door frame, and a locking structure is provided between the door frames.

[0006] Preferably, the bottom of the side panel is provided with a first rotating shaft, and the bottom plate is provided with a first limiting groove at the position corresponding to the first rotating shaft, and the first rotating shaft is rotatably disposed in the first limiting groove.

[0007] Preferably, the inner side of the first limiting groove is provided with a first limiting protrusion and a second limiting protrusion disposed opposite to each other, the first limiting protrusion and the second limiting protrusion being used to abut against the first rotating shaft to limit the first rotating shaft within the first limiting groove.

[0008] Preferably, an elastic pressure plate is provided in the first limiting groove, the elastic pressure plate is arranged parallel to the bottom plate, and the first limiting protrusion is provided on the side of the elastic pressure plate facing the bottom plate.

[0009] Preferably, the first limiting groove is disposed on the side wall of the base plate, and at least one of the first limiting grooves extends from the top of the side wall of the base plate through the side wall to the bottom surface of the receiving groove.

[0010] Preferably, a second pivot is provided on the side of the side panel, and a second limiting groove is provided on the adjacent side panel at the position corresponding to the second pivot. The second pivot is detachably rotatably connected to the second limiting groove.

[0011] Preferably, the door panel includes a first door panel and a second door panel arranged in parallel, and the door frame is provided with a first sliding groove and a second sliding groove at positions corresponding to the first door panel and the second door panel, respectively.

[0012] Preferably, the locking structure includes a first magnet disposed on the first door panel and the second door panel, and a second magnet is disposed on the door frame at a position corresponding to the first magnet.

[0013] Preferably, it also includes a cover plate, which is placed on top of the side panel to close the storage box.

[0014] Compared with the prior art, the foldable storage box provided in this embodiment of the present invention has the following advantages:

[0015] In this invention, adjacent side panels are rotatably connected and also rotatably connected to the bottom plate. When subjected to external pressure, the rotation axes between the side panels, the bottom plate, and other side panels constrain each other, thereby limiting the movement of the side panels. This makes the structure of the storage box more stable and reliable, less prone to deflection and loosening. When items need to be retrieved, the storage box can be easily opened and retrieved through the sliding door. When folding is required, the side panels can be moved from the inside out to disconnect the rotatable connection structure between adjacent side panels, allowing each side panel to rotate relative to the bottom plate, thus realizing the folding of the storage box. The entire folding process of the storage box is more convenient and faster. Attached Figure Description

[0022] 3. Cover plate. Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 4 As shown, a preferred embodiment of this utility model provides a foldable storage box, which includes a bottom plate 1 and multiple side panels 2. The bottom plate 1 and the multiple side panels 2 are closed to form a storage box. The bottom of the side panels 2 is rotatably connected to the bottom plate 1, and two adjacent side panels 2 are rotatably connected. The bottom plate 1 is provided with a receiving groove 11 for receiving the multiple side panels 2 after folding.

[0025] At least one side panel 2 includes a door frame 21, a door panel is provided inside the door frame 21, the door panel is slidably connected to the door frame 21, and a locking structure is provided between the door frames 21.

[0026] Specifically, in this embodiment, each side panel 2 is rotatably connected to the bottom plate 1 and the two adjacent side panels 2. In the unfolded state, the rotation axis of the bottom of the side panel 2 is perpendicular to the rotation axis of its side, thereby effectively restricting the movement of the side panel 2. When the side panel 2 of the storage box is subjected to external pressure, due to the restriction of the side connection structure of the side panel 2, the top of the side panel 2 cannot be flipped inward to the inside of the storage box. The restriction of the bottom connection structure of the side panel 2 also prevents the side of the side panel 2 from tilting inward, so that the storage box can also ensure the stability of the overall structure when subjected to external pressure.

[0027] Meanwhile, compared to a purely snap-fit ​​structure, the rotating connection between the side panels 2 allows for relative rotation between the side panels 2. When the storage box needs to be folded, gently push the side panel 2 from the inside out to disengage it from the adjacent side panel 2, that is, to disengage the rotating shaft from the rotating groove. Then, the side panels 2 can be flipped over, so that the side panels 2 are folded and stored in the receiving groove 11 of the bottom plate 1. Compared to the snap-fit ​​structure, this is undoubtedly more labor-saving and simpler. The entire folding and storage process is simpler and faster, and it can also withstand external pressure well.

[0028] Furthermore, in another embodiment, when the storage box needs to be folded, only one side of the side panel 2 can be disconnected, causing the rotating shaft on one side of the side panel 2 to disengage from the rotating groove. Then, pressure is applied to the side panel 2 from the outside of the storage box, causing the side panel 2 to rotate around the rotating shaft on its other side and fold to the inner side of the adjacent side panel 2. The side panel 2 is then folded into the receiving groove 11, eliminating the hassle of unfastening both sides of the side panel 2 as in traditional snap-fit ​​solutions, making the folding of the storage box more convenient and quick. Furthermore, in another embodiment, the side panel 2 can also be flipped outwards to the adjacent side panel 2, thereby maximizing the opening of the side of the storage box and further facilitating the user to find items inside.

[0029] In some embodiments, a first rotating shaft 24 is provided at the bottom of the side panel 2, and a first limiting groove 12 is provided at the position corresponding to the first rotating shaft 24 on the bottom plate 1. The first rotating shaft 24 is rotatably disposed within the first limiting groove 12. Further, a first limiting protrusion 121 and a second limiting protrusion 122 are provided on the inner side of the first limiting groove 12, which are oppositely disposed. The first limiting protrusion 121 and the second limiting protrusion 122 are used to abut against the first rotating shaft 24 to limit the first rotating shaft 24 within the first limiting groove 12.

[0030] Specifically, in the actual product, multiple first rotating shafts 24 and first limiting grooves 12 are provided. The opening of the first limiting groove 12 can face the inside of the receiving groove 11, the top of the storage box, or the side away from the receiving groove 11. The first limiting protrusion 121 and the second limiting protrusion 122 inside the first limiting groove 12 are arranged opposite each other. When the first rotating shaft 24 is engaged in the first limiting groove 12, the first limiting protrusion 121 and the second limiting protrusion 122 can reduce the inner width of the first limiting groove 12, thereby restricting the movement of the first rotating shaft 24 and preventing the first rotating shaft 24 from disengaging from the first limiting groove 12.

[0031] In some embodiments, an elastic pressure plate 123 is provided in the first limiting groove 12. The elastic pressure plate 123 is arranged parallel to the bottom plate 1, and a first limiting protrusion 121 is provided on the side of the elastic pressure plate 123 facing the bottom plate 1.

[0032] Specifically, the elastic pressure plate 123 is set parallel to the bottom plate 1. When the storage box is in the unfolded state, the bottom of the side panel 2 will press down on the elastic pressure plate 123, making the first limiting protrusion 121 closer to the second limiting protrusion 122, thereby better restricting the position of the first rotating shaft 24 and preventing the first rotating shaft 24 from disengaging from the first limiting groove 12. In particular, when the side panel 2 of the storage box is subjected to pressure from the vertical direction above, the connection between the side panel 2 and the bottom plate 1 is more compact and stable.

[0033] In other embodiments, a first limiting groove 12 is disposed on the side wall of the base plate 1, and at least one first limiting groove 12 extends from the top of the side wall of the base plate 1 through the side wall to the bottom surface of the receiving groove 11. A portion of the first limiting groove 12 extends to the bottom surface of the receiving groove 11. When the side panel 2 needs to be folded and stored, the side panel 2 at the bottom after folding can slide along the first limiting groove 12 towards the bottom surface of the receiving groove 11, thereby storing the side panel 2 at the bottom of the receiving groove 11. The remaining side panels 2 are then stacked on top of this side panel 2, allowing multiple side panels 2 to be staggered during folding, making the entire folding process simpler and more convenient. Furthermore, when the first limiting grooves 12 of multiple side panels 2 are all configured in this way, the folding of the side panels 2 no longer requires distinguishing the folding order, further improving the convenience of folding the storage box.

[0034] In some embodiments, a second pivot 25 is provided on the side of the side panel 2, and a second limiting groove 26 is provided on the adjacent side panel 2 at the position corresponding to the second pivot 25. The second pivot 25 is detachably rotatably connected to the second limiting groove 26.

[0035] Specifically, this embodiment includes two scenarios: in one scenario, a second pivot 25 is provided on one side of each side of the side panel 2, and a second limiting groove 26 is provided on the other side; in the other scenario, a second pivot 25 is provided on both sides of a portion of the side panel 2, while a second limiting groove 26 is provided on both sides of the unclosed side panel 2. During the actual folding process, the side panel 2 can be folded towards another side panel 2 first, and then folded together into the receiving groove 11, or each panel can be individually flipped into the receiving groove 11. When retrieving items, the side panel 2 can be flipped outwards to open it for easy access to the items inside the storage box. The second pivot 25 is vertically positioned, which better withstands pressure from above and sides. Its larger cross-sectional area and higher strength make the entire storage box less prone to bending, deflection, or structural breakage when facing external pressure and thrust, resulting in a more stable and reliable structure.

[0036] In some embodiments, the door panels include a first door panel 22 and a second door panel 23 arranged in parallel. The door frame 21 is provided with a first sliding groove 211 and a second sliding groove 212 at positions corresponding to the first door panel 22 and the second door panel 23, respectively. Furthermore, the locking structure includes a first magnet 27 disposed on the first door panel 22 and the second door panel 23, and a second magnet 28 disposed on the door frame 21 at positions corresponding to the first magnet 27. In practice, when it is necessary to retrieve an item, the first door panel 22 or the second door panel 23 can be pushed to slide until it overlaps with the other door panel, thereby opening the space on one side of the storage box for easy access to items on that side. The two door panels can completely cover the opening in the middle of the door frame 21, thus protecting the items stored in the storage box. The cooperation of the first magnet 27 and the second magnet 28 can stabilize the positions of the first door panel 22 and the second door panel 23, preventing them from sliding due to external vibrations or impacts, and ensuring the stability of the positions of the first door panel 22 and the second door panel 23.

[0037] In some embodiments, a cover plate 3 is also included, which is placed on top of the side panel 2 to close the storage box. The cover plate 3 and the side panel 2 can be simply overlapped together, or an additional snap-fit ​​structure can be provided to snap the cover plate 3 to at least one side panel 2. The cover plate 3 can protect the items inside the storage box and also prevent dust and other adverse external factors from entering the storage box and affecting the items stored inside.

[0038] In summary, this utility model embodiment provides a folding storage box that changes the connection method between the side panels 2 and provides a sliding door structure on the side panels 2. In the rotational connection structure between the side panels 2, the second rotating shaft 25 acts as a support beam. The perpendicularity between the first rotating shaft 24 and the second rotating shaft 25 restricts the movement of the side panels 2 in the unfolded state, improves the structural strength of the side panels 2 in the unfolded state, and makes it less likely for the side panels 2 to flip or deflect when subjected to external pressure. The connection structure is also less prone to breakage, allowing the storage box to better withstand external pressure.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
