Description

TECHNICAL FIELD

[0001] The utility model relates to the field of storage box, especially a folding storage box. BACKGROUND

[0002] As a common household product, the storage box can provide stable storage space for many sundries in the room, and facilitates users to neatly store sundries. When not in use, the storage box can be folded and stored, thereby reducing the storage space of the storage box itself.

[0003] However, the existing storage box still has many problems. In the existing storage box, the four side plates located on the side are rotatably connected with the bottom plate. When folding, the side plates are folded from the top of the bottom plate to the bottom plate. When the storage box is unfolded, the overall structure has low strength, and the connection between the side plate and the bottom plate is prone to rotation and other instability problems. In addition, when facing a rectangular storage box with a higher height, the side plate needs to be additionally divided into two parts rotatably connected. After the side plate is folded, it can be folded again towards the bottom plate. This not only reduces the overall structural strength of the storage box, but also makes the structure and use process of the storage box more complex. At the same time, the thickness of the folded storage box is also increased due to the folding of the side plate. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a new folding structure to make the unfolded structure of the storage box more stable and the folding process simpler and faster. To solve the above technical problem, the utility model provides a folding storage box, which comprises a bottom plate and a side plate group.

[0005] The side plate group comprises a first side plate and a second side plate. The first side plate is rotatably connected with the bottom plate to fold the first side plate to the bottom surface or the top surface of the bottom plate. The second side plate is rotatably connected with the first side plate to fold the second side plate to be stacked with the first side plate. The rotation axis of the first side plate is perpendicular to the rotation axis of the second side plate. The second side plate is clamped with the bottom plate and the first side plate in the other side plate group.

[0006] Preferably, the bottom plate is provided with a groove, and a rotating part is arranged in the groove.

[0007] The rotating part is provided with a first rotating groove and a second rotating groove. The first rotating groove and the second rotating groove are arranged in parallel. The first side plate is provided with a first rotating shaft corresponding to the first rotating groove. The bottom plate is provided with a second rotating shaft corresponding to the second rotating groove.

[0008] Preferably, the bottom plate is provided with a second accommodating groove, a through hole is arranged in the second accommodating groove, and the first side plate is provided with a fourth rotating shaft corresponding to the through hole.

[0009] Preferably, the first side plate is provided with a third rotating groove, and the second side plate is provided with a third rotating shaft corresponding to the third rotating groove.

[0010] Preferably, the second side plate is provided with a first accommodating groove on a side away from the third rotating shaft, and a first limiting protrusion is arranged on the inner side of the first accommodating groove; the first side plate is provided with a limiting plate, the limiting plate is provided with a first clamping groove, the limiting plate is clamped into the first accommodating groove of the second side plate of the other side plate group, and the first limiting protrusion is clamped into the first clamping groove.

[0011] Preferably, the bottom plate is provided with a second limiting protrusion, and the bottom of the second side plate is provided with a second clamping groove corresponding to the second limiting protrusion.

[0012] Preferably, the utility model also comprises a top plate, and the first side plate and the second side plate are detachably connected with the top plate.

[0013] Preferably, the top plate comprises a plate frame, a cover plate is rotatably connected to the plate frame, one side of the plate frame is provided with a third clamping groove, and the first side plate and the second side plate are provided with third limiting protrusions corresponding to the third clamping groove.

[0014] Compared with the prior art, the folding storage box provided in the embodiment of the utility model has the following beneficial effects:

[0015] In the utility model, the second side plate is rotatably connected with the first side plate instead of the bottom plate, and when folding and storing, the second side plate is folded to the inner side of the first side plate, and then the first side plate is turned to the top surface or bottom surface of the bottom plate, and the first side plate on the other side is also turned to the bottom surface or top surface of the bottom plate after storing the second side plate, so that the thickness of the storage box after folding is only five layers of plates, and compared with the technical scheme in which the side plate itself is folded and then folded to the bottom plate when facing a side plate with a higher height, the thickness of the storage box after folding in the utility model is thinner, and the overall strength is higher and the structure is more stable due to fewer movable structures; and in the unfolded state, the first side plate is not easy to be pushed to turn due to the unfolding of the second side plate, the strength is higher, the whole structure is more stable and reliable, and the rotating shaft of the second side plate is perpendicular to the bottom plate, so that the strength is higher and the problem of rotation of the side plate under the top pressure in the traditional scheme does not easily occur, and the structure is more stable.

Specific implementation

[0021] The specific implementation of the utility model is described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0022] As Figs. 1 to 4 shown, the utility model preferred embodiment provides a kind of folding storage box, it includes bottom plate 1 and side plate group 2, side plate group 2 is rotatably connected with bottom plate 1, and is detachably connected with another side plate group 2, bottom plate 1 is combined with side plate group 2 to form storage box;

[0023] Side plate group 2 includes first side plate 21 and second side plate 22, first side plate 21 is rotatably connected with bottom plate 1, to fold first side plate 21 to the bottom surface or top surface of bottom plate 1;Second side plate 22 is rotatably connected with first side plate 21, to fold second side plate 22 to be placed with first side plate 21;The rotation axis of first side plate 21 is perpendicular to the rotation axis of second side plate 22, and second side plate 22 is clamped with bottom plate 1 and the first side plate 21 in another side plate group 2.

[0024] Specifically, in the embodiment, the four side plates of the storage box are divided into two side plate groups 2, each of which includes a first side plate 21 and a second side plate 22 connected by rotation, in the unfolded state of the storage box, the first side plate 21 and the second side plate 22 are perpendicular to each other and perpendicular to the bottom plate 1. Compared with the traditional scheme in which the four side plates are all connected with the bottom plate 1 by rotation and are all folded upwards to the bottom plate 1, in the embodiment, the first side plate 21 is no longer connected with the bottom plate 1 by rotation, but is connected with the second side plate 22 by rotation, and in the unfolded state of the storage box, the second side plate 22 is clamped with the bottom plate 1 and the second side plate 22 in the other side plate group 2. When the first side plate 21 is subjected to external pushing force or pulling force, the second side plate 22 will provide more stable and reliable support for the first side plate 21. When the second side plate 22 is not folded to the inner side of the first side plate 21, it is almost impossible to fold the first side plate 21. The structure of the entire storage box is obviously more stable and reliable than the traditional storage box which relies on the fragile clamping structure between the side plates to keep the side plates from being folded.

[0025] Secondly, when multiple storage boxes are stacked and the top of the storage box bears a large pressure, in the traditional storage box, because the side plate and the bottom plate 1 are connected by rotation, under the continuous pressure of external pressure, the pivot of the side plate is easy to deflect and rotate. Under the long-term pressure, it will cause further imbalance of the force structure of the entire storage box, and the clamping result between the side plates will be crushed and failed under the pressure, and then multiple side plates will be folded to the inside of the storage box, and the entire storage box will be destroyed. In the embodiment, because the axis of rotation between the second side plate 22 and the first side plate 21 is perpendicular to the bottom plate 1, its pivot structure can act as a column effect, and can better bear the pressure from the top of the storage box, and its structure is more stable and reliable, and has stronger carrying capacity.

[0026] Finally, when the storage box needs to be folded, the second side plate 22 is first driven to be separated from the bottom plate 1 and the first side plate 21 in the other side plate set 2, and then the second side plate 22 is flipped to the inside or outside of the first side plate 21, so that the second side plate 22 is stacked with the first side plate 21, and then the first side plate 21 is flipped to the bottom surface and the top surface of the bottom plate 1. The whole folding structure is simpler, and the folding process is more concise and rapid. After the storage box is folded, the thickness of the storage box is about the sum of the thicknesses of five plate bodies. Of course, in this embodiment, the square storage box is mainly used, or the storage box is more suitable for the side plate height being not greater than the side length of the bottom plate 1. In some other embodiments, the two first side plates 21 can also be connected to ensure the stability of the folded storage box, so that the plate bodies in the folded storage box are not easy to spread out. At the same time, in some other embodiments, the height of the cuboid is less than the side length of the bottom plate 1, and the two second side plates 22 can be flipped to the same side of the first side plate 21. In this embodiment, the thickness of the whole folded storage box is the thickness of four plate bodies, which is smaller, and can be better placed in various gaps, such as the gap between the refrigerator and the wall or the gap under the bed. The area of the gap is large, but the thickness is required. It is more convenient to store the folded storage box. In the traditional scheme, when the height of the side plate is greater than the side length of the bottom plate 1, the side plate is divided into upper and lower parts. When folding, the side plate is folded once by itself, and then the side plate is folded on the bottom plate 1. Although the area of the folded storage box is reduced, the thickness is increased, which is not suitable for some special cases requiring thickness. In addition, the side plate is additionally divided into two parts connected by rotation, which not only increases the complexity of the mechanism and the complexity of the folding process of the storage box, but also reduces the structural strength of the side plate itself, thereby reducing the structural strength of the whole storage box.

[0027] In some embodiments, the bottom plate 1 is provided with a groove 11, and the groove 11 is provided with a rotating part 3;

[0028] The rotating part 3 is provided with a first rotating groove 31 and a second rotating groove 32, and the first rotating groove 31 and the second rotating groove 32 are arranged in parallel. The first side plate 21 is provided with a first rotating shaft 211 corresponding to the first rotating groove 31, and the bottom plate 1 is provided with a second rotating shaft 12 corresponding to the second rotating groove 32.

[0029] Specifically, in this embodiment, the first side plate 21 needs to be rotated to the bottom surface of the bottom plate 1, so the rotating part 3 is additionally provided. The bottom plate 1 and the first side plate 21 are respectively connected with the rotating part 3 by rotation, so that the bottom plate 1 and the first side plate 21 can rotate relative to the rotating part 3, thereby facilitating the rotation of the first side plate 21 to the bottom of the bottom plate 1.

[0030] Of course, in some other embodiments, the bottom plate 1 is provided with a second accommodating groove 13, a through hole is arranged in the second accommodating groove 13, and the first side plate 21 is provided with a fourth rotating shaft corresponding to the through hole. The first side plate 21 can also be directly connected with the bottom plate 1 in rotation. In this embodiment, the structure of the bottom plate 1 needs to be adjusted, so that there is a clearance area on the side edge of the bottom plate 1, thereby facilitating the overturning of the first side plate 21 to the bottom surface of the bottom plate 1. When the first side plate 21 only needs to be overturned to the top of the bottom plate 1, an additional clearance area is not needed.

[0031] In addition, the first rotating groove 31 and the second rotating groove 32 both include a guide groove and a limiting groove. The opening part of the guide groove is large, and gradually narrows inward, thereby guiding the first rotating shaft 211 or the second rotating shaft 12, so that the first rotating shaft 211 or the second rotating shaft 12 can smoothly enter the limiting groove. The limiting groove is in an "L" shape relative to the guide groove, and can clamp the first rotating shaft 211 and the second rotating shaft 12, thereby avoiding the rotating shaft from being separated from the limiting groove under the action of an external force.

[0032] Further, the first side plate 21 is provided with a third rotating groove 212, and the second side plate 22 is provided with a third rotating shaft 221 corresponding to the third rotating groove 212. The third rotating shaft 221 rotates in the third rotating groove 212 to drive the second side plate 22 to rotate relative to the first side plate 21. The axis of the third rotating shaft 221 is perpendicular to the bottom plate 1, which can better withstand external tension, thereby improving the carrying strength of the entire storage box. When the second side plate 22 is not folded back to the first side plate 21, the third rotating shaft 221 also provides more stable support for the first side plate 21. In the unfolded state, the first side plate 21 is almost impossible to be overturned, and the overall structural strength is higher. When the storage box is unfolded for use, the second side plate 22 will not be overturned due to external force because of the existence of the items inside, thereby improving the overall structural strength.

[0033] In some embodiments, the second side plate 22 is provided with a first accommodating groove 222 on the side away from the third rotating shaft 221, and a first limiting protrusion 2221 is arranged on the inner side of the first accommodating groove 222. The first side plate 21 is provided with a limiting plate 241, and the limiting plate 241 is provided with a first clamping groove 2411. The limiting plate 241 is clamped into the first accommodating groove 222 of the second side plate 22 of the other side plate group 2, and the first limiting protrusion 2221 is clamped into the first clamping groove 2411.

[0034] Specifically, in this embodiment, the first accommodating groove 222 on the second side plate 22 corresponds to the limiting plate 241 on the first side plate 21 of the other side plate group 2, and in the unfolded state, the two sides of the second side plate 22 are both connected with the first side plate 21, one side is rotatably connected with the first side plate 21, and the other side is detachably clamped with the other first side plate 21, by clamping the limiting plate 241 into the first accommodating groove 222 and clamping the first limiting protrusion 2221 into the first clamping groove 2411, the clamping between the second side plate 22 and the first side plate 21 in the unfolded state is more stable and reliable, and the strength of the entire storage box in the unfolded state is higher.

[0035] In other embodiments, the bottom plate 1 is provided with a second limiting protrusion 14, and the bottom of the second side plate 22 is provided with a second clamping groove corresponding to the second limiting protrusion 14. By matching the second limiting protrusion 14 on the bottom plate 1 with the second clamping groove, the position of the second side plate 22 in the unfolded state can be further limited and stabilized, the structure of the storage box is more stable, the strength is better, and the storage box is not easy to overturn under external pressure in the unfolded state. Of course, in other embodiments, the bottom plate 1 can be provided with a second clamping groove, and the second side plate 22 can be provided with a second limiting protrusion 14.

[0036] In some embodiments, the top plate 4 is further detachably connected with the first side plate 21 and the second side plate 22. Further, the top plate 4 includes a plate frame 41 rotatably connected with a cover plate 42, and one side of the plate frame 41 is provided with a third clamping groove, and the first side plate 21 and the second side plate 22 are provided with a third limiting protrusion 5 corresponding to the third clamping groove.

[0037] The third limiting protrusion 5 of the top of the first side plate 21 and the second side plate 22 is inserted into the third clamping groove to connect the plate frame 41 with the first side plate 21 and the second side plate 22, which limits the relative position of the first side plate 21 and the second side plate 22, connects the two first side plates 21 and the two second side plates 22, and improves the stability of the structure of the storage box in the unfolded state.

[0038] In summary, the utility model embodiment provides a folding storage box, which changes the technical scheme in the prior art that all side plates are rotatably connected with the bottom plate 1, and makes the second side plate 22 rotatably connected with the first side plate 21, and makes the second side plate 22 clamped with the other first side plate 21 and the bottom plate 1, and vertically places the rotating shaft of the second side plate 22, thereby improving the structural strength and stability of the entire storage box after unfolding, and also making the structure of the storage box more simple and the folding process more simple and convenient.

[0039] The above are only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
