[0002] This utility model belongs to the technical field of household items, and relates to a storage cabinet, particularly a stackable folding storage cabinet. Background Technology
[0003] Storage boxes and cabinets are commonly used storage containers. Folding storage boxes can reduce packaging volume, leading to increasing production and sales. There is also a growing body of literature on folding storage boxes and stackable folding cabinets. For example, one folding storage box (patent number ZL201720702871.7) typically uses TPE / TPR materials for its connecting parts, while the remaining parts are made of other materials such as PP. The box is manufactured using a two-stage injection molding process; however, this method suffers from high investment and manufacturing costs.
[0004] Another example is a foldable storage box and a storage cabinet made by stacking the storage boxes (patent number ZL202320533298.7). The four side walls, bottom wall and door of the storage box are all made independently and then need to be assembled, which has the problems of high investment cost and high manufacturing cost. Summary of the Invention
[0005] This utility model proposes a folding storage box. The technical problem to be solved by this utility model is how to reduce the investment cost and manufacturing cost of the folding storage box.
[0006] This utility model proposes a folding storage box. The technical problem to be solved by this utility model is how to reduce the investment cost and manufacturing cost of stackable folding storage cabinets.
[0007] The technical problem to be solved by this utility model can be achieved through the following technical solution: A folding storage box, characterized in that it includes an integral box body and a bottom plate. The box body has four side walls. The first and second side walls, which are arranged opposite each other, cannot be folded. The third and fourth side walls, which are arranged opposite each other, can be folded. The third and fourth side walls are each divided into thick-walled areas and thin-walled areas located between two adjacent thick-walled areas. The thin-walled areas are strip-shaped and vertically arranged, and there are three thin-walled areas. One side of the bottom plate is rotatably connected to the bottom edge of the first side wall through a shaft. The bottom edge of the second side wall, the bottom edge of the thick-walled area in the third side wall, and the bottom edge of the thick-walled area in the fourth side wall all have a bearing part. The side edge of the bottom plate is in contact with the top surface of the bearing part. The side edge of the bottom plate and the bearing part are also connected by a positioning structure. When the bottom plate is in the flipped-up state, the thin-walled areas in the third and fourth side walls can be bent to make the box body folded.
[0008] Compared with existing technologies, the body of this folding storage box is a one-piece design, requiring only one set of molds and being injection molded in one go. The shaft connection structure between the body and the bottom plate has the advantage of easy assembly. Therefore, this folding storage box has the advantages of low investment cost and low manufacturing cost.

[0038] A folding storage box 10 includes an integrated box body 1 and a base plate 2.
[0039] The box body 1 is made of plastic material and has four side walls, which are referred to as the first side wall 1-1, the second side wall 1-2, the third side wall 1-3 and the fourth side wall 1-4 respectively. The first side wall 1-1 and the second side wall 1-2 are arranged opposite to each other and cannot be folded. The third side wall 1-3 and the fourth side wall 1-4 are arranged opposite to each other and can be folded.
[0040] Both the third sidewall 1-3 and the fourth sidewall 1-4 are divided into a thick-walled region 1a and a thin-walled region 1b located between two adjacent thick-walled regions 1a. The thin-walled regions 1b are strip-shaped and vertically arranged, and there are three thin-walled regions 1b. Specifically, from the first sidewall 1-1 to the second sidewall 1-2, they are the first thick-walled region 1a, the thin-walled region 1b, the second thick-walled region 1a, the thin-walled region 1b, the third thick-walled region 1a, and the thin-walled region 1b.
[0041] One side of the base plate 2 is rotatably connected to the bottom edge of the first side wall 1-1 via a shaft 3. The first thick-walled region 1a of the third side wall 1-3 and the first thick-walled region 1a of the fourth side wall 1-4 form a receiving area for the base plate 2. The bottom edges of the second side wall 1-2, the third side wall 1-3, and the fourth side wall 1-4 all have a supporting part 1c, the top surface of which is the supporting surface. When the folding storage box 10 is in the unfolded state, the side edge of the base plate 2 contacts the top surface of the supporting part 1c, and the side edge of the base plate 2 and the supporting part 1c are also connected by a positioning structure.
[0042] The positioning structure includes a positioning groove 1d on the top surface of the supporting part 1c, and a positioning plug 2a on the side of the base plate 2 that corresponds one-to-one with the positioning groove 1d. Thus, when the folding storage box 10 is in the unfolded state, the positioning plug 2a is embedded in the positioning groove 1d. Depending on the actual situation, the positions of the positioning groove 1d and the positioning plug 2a can be interchanged.
[0043] By explaining the process of switching between the unfolded and folded states of the folding storage box 10, the function and advantages of each component are further illustrated. When the folding storage box 10 switches from the unfolded state to the folded state, the bottom plate 2 is first flipped upwards, and the bottom plate 2 is located between the first thick wall region 1a of the third side wall 1-3 and the first thick wall region 1a of the fourth side wall 1-4. Then, the middle parts of the third side wall 1-3 and the fourth side wall 1-4 are pushed towards the inside of the storage box cavity. The thin wall region 1b in the third side wall 1-3 and the thin wall region 1b in the fourth side wall 1-4 are both bent. The third side wall 1-3 and the fourth side wall 1-4 are gradually folded, and the distance between the first side wall 1-1 and the second side wall 1-2 is reduced until the second thick wall region 1a and the third thick wall region 1a are against each other.
[0044] When the folding storage box 10 switches from the folded state to the unfolded state, the first sidewall 1-1 and the second sidewall 1-2 are stretched first, increasing the distance between the first sidewall 1-1 and the second sidewall 1-2. The thin-walled region 1b in the third sidewall 1-3 and the thin-walled region 1b in the fourth sidewall 1-4 gradually unfold until the sides of the second thick-walled region 1a and the third thick-walled region 1a are flush. Then the bottom plate 2 is flipped downwards. When the folding storage box 10 is in the unfolded state, the bottom plate 2 is located between the bottoms of the four sidewalls. The bottom surface of the bottom plate 2 contacts the top surface of the bearing part 1c, the inner side of the sidewall contacts the side of the bottom plate 2, the positioning plug 2a is embedded in the positioning groove 1d, and the side of the positioning plug 2a contacts the side of the positioning groove 1d. This improves the load-bearing capacity of the folding storage box 10 in the unfolded state and also improves the strength of the folding storage box 10.
[0045] A stackable folding storage cabinet includes multiple stacked folding storage boxes 10. The attached drawings show that there are 3 folding storage boxes 10. The number of folding storage boxes 10 can be increased or decreased according to the actual situation, such as 2, 4 or 5 folding storage boxes 10.
[0046] A stacking connecting ring 20 is provided between two adjacent folding storage boxes 10. A retrieval opening is provided on the first side wall 1-1 or the second side wall 1-2 of the folding storage box 10, and a door 30 is provided at the retrieval opening. This not only makes it easy to retrieve and put away items, but also makes it easier to store items.
[0047] The bottom surface of the stacked connecting ring 20 is provided with a lower connecting groove 20b, and the top surface of the stacked connecting ring 20 is provided with an upper connecting groove 20a. The top edge area of the box body 1 in the folding storage box 10 is embedded in the lower connecting groove 20b, and the bottom edge area of the box body 1 is embedded in the lower connecting groove 20b.
[0048] Multiple buckles 40 are connected to the stacked connecting ring 20. The top of the box body 1 in the folding storage box 10 has an outwardly extending flange 1e. The hook of the buckle 40 contacts the bottom surface of the flange 1e, which not only improves the strength of the top of the box body 1, but also enhances the connection between the stacked connecting ring 20 and the box body 1. The bottom of the box body 1 in the folding storage box 10 is provided with a snap-fit part 1f that matches the hook of the buckle 40. The hook of the buckle 40 contacts the top surface of the snap-fit part 1f, which further enhances the connection between the stacked connecting ring 20 and the box body 1.
[0049] A stackable folding storage cabinet also includes a top cover 50 located at the opening of the topmost folding storage box 10.
