Description

Technical Field

[0001] This utility model relates to a storage rack, specifically a modular storage rack. Background Technology

[0002] For processing, packaging, warehousing, and transportation considerations, many storage racks on the market currently adopt a modular design. These modular racks typically consist of multiple shelves, with adjacent shelves connected at their four corners by interlocking support posts. The bottom of the support post interlocks with the top holes of the shelf, and the top of the support post interlocks with the bottom holes of the shelf above it. Years of use have revealed that this direct interlocking structure lacks sufficient connection strength and overall support capacity. When heavy items are placed on it, it easily tilts and tips over, causing significant inconvenience in actual use. Utility Model Content

[0003] To address the aforementioned issues, this utility model presents a modular storage rack, comprising two vertical panels on the left and right and multiple shelves. The two side walls of each shelf are connected to the vertical panels via at least one set of snap-fit ​​structures. The entire storage rack features good modular connection and high support strength.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A modular storage rack is characterized by comprising two vertical panels on the left and right and multiple shelves. The two side walls of each shelf are connected to the inner wall of the vertical panel by at least one set of snap-fit ​​structures. Each set of snap-fit ​​structures includes a latch on the side wall of the shelf and a slot on the inner wall of the vertical panel. The latch protrudes on both sides, and the slot has an open top. A U-shaped notch is provided on the front side plate of the slot for the latch to engage.

[0005] More specifically, the U-shaped notch has symmetrical locking protrusions on both sides of the opening. The locking protrusions are two-step protrusion structures. The entire locking protrusion consists of a thin upper protrusion and a thick lower protrusion. The upper and lower protrusions are smoothly connected by an arc surface. The thickness of the upper protrusion gradually increases from top to bottom, and the thickness of the lower protrusion also gradually increases from top to bottom.

[0006] More specifically, the aforementioned vertical plate has a locking protrusion at the top slot of each corresponding slot. The surface of the locking protrusion is set as an inclined surface so that its thickness gradually increases from top to bottom. When the latch is fully inserted into the corresponding slot, the bottom surface of the locking protrusion abuts against the top of the latch.

[0007] More specifically, the aforementioned vertical plate has perforated holes on the rear wall of the corresponding slot.

[0008] More specifically, the rear side of the aforementioned vertical plate is bent to form a rear connecting plate, and the rear connecting plate is provided with a wall-mounting hole that can be connected to a wall hook.

[0009] More specifically, the front side of the aforementioned vertical plate is bent to form the front edge.

[0010] More specifically, a bottom plate is provided between the bottoms of the two vertical plates, and a top plate is provided between the tops of the two vertical plates. A retrieval opening is formed between the bottom plate, the top plate, and the front edge of the two vertical plates, and an openable and closable cabinet door is provided on the retrieval opening.

[0011] More specifically, the cabinet door is configured as a single door or a double door, with a connecting shaft at the top and bottom of one side of the cabinet door, and the two connecting shafts are movably connected to the shaft holes on the top plate and bottom plate, respectively.

[0012] More specifically, the cabinet doors are equipped with handles.

[0013] This utility model designs a modular storage rack, which comprises two vertical panels on the left and right sides and multiple shelves. Each shelf's side walls are connected to the vertical panels via at least one set of snap-fit ​​structures. Compared to existing support rod configurations, this vertical panel structure not only ensures the combined strength of the vertical panels and shelves but also effectively enhances the support strength for each shelf.

Detailed Implementation

[0015] like Figure 1-4 As shown, a modular storage rack includes two vertical panels 1 on the left and right and multiple shelves 2. This illustration only describes the structure of three shelves 2. In practice, it can be configured with two or more shelves 2 as needed.

[0016] To facilitate placement and storage, the middle of the shelf 2 is recessed to form a corresponding storage groove 21.

[0017] Each shelf 2 has two side walls that are engaged with the inner wall of the vertical plate 1 by at least one set of snap-fit ​​structures 3. The shelf 2 in this figure is illustrated by two sets of snap-fit ​​structures 3 on each side. In practice, the number of snap-fit ​​structures 3 should be determined according to the width of the shelf 2. When it is relatively narrow, only one set can be used, while when it is relatively wide, three or even more sets of snap-fit ​​structures 3 can be used.

[0018] Each set of snap-fit ​​structures 3 includes a snap tongue 31 on the side wall of the shelf 2 and a slot 32 on the inner wall of the vertical plate 1.

[0019] The latch 31 is a T-shaped structure with protrusions on both sides.

[0020] The slot 32 has an open top structure, and a U-shaped notch 321 is provided on the front side plate of the slot 32 for the insertion of the latch 31.

[0021] To ensure effective locking of the latch 31 after it is engaged in the slot 32, vertically arranged locking protrusions 322 are symmetrically arranged on both sides of the opening of the U-shaped notch 321. The locking protrusions 322 are two-step protrusion structures. The entire locking protrusion 322 is composed of a thin upper protrusion 3221 and a thick lower protrusion 3222. The upper protrusion 3221 and the lower protrusion 3222 are smoothly connected by an arc surface 3223. The thickness of the upper protrusion 3221 gradually increases from top to bottom, and the thickness of the lower protrusion 3222 also gradually increases from top to bottom.

[0022] During assembly, when the latch 31 is first inserted into the slot 32, the outer wall of the corresponding shelf 2 on the inner side of the latch 31 aligns with the upper protrusion 3221. Because the upper protrusion 3221 is relatively thin, there is no mutual squeezing between the two, ensuring smooth insertion of the latch 31. As the latch 31 continues to be inserted, once it passes the arc surface 3223 between the upper and lower protrusions, the outer wall of the shelf 2 will align with the lower protrusion 3222. Compared to the upper protrusion 3221, the thickness of the lower protrusion 3222 suddenly increases. This causes the outer wall of the shelf 2 to create a squeezing effect with the surface of the lower protrusion 3222. The thickness of the lower protrusion 3222 gradually increases from top to bottom, making the squeezing effect more pronounced as the latch 31 is inserted into the slot 32, resulting in a better locking effect between the latch 31 and the slot 32.

[0023] Furthermore, to ensure effective locking after the latch 31 is fully inserted into the slot 32, the vertical plate 1 is provided with a locking protrusion 33 at the top opening of each slot 32. The surface of the locking protrusion 33 is set as an inclined surface 331, so that its thickness gradually increases from top to bottom. The inclined surface 331 structure of the locking protrusion 33 can guide the latch 31 when it is inserted into the slot 32, ensuring that the latch 31 is inserted into the slot 32 with less effort. When the latch 31 is fully inserted into the corresponding slot 32, the bottom surface of the locking protrusion 33 will abut against the top of the latch 31 to achieve locking, which can prevent the latch 31 from loosening or falling off during use and ensure the stability of the connection between the latch 31 and the slot 32.

[0024] Considering the need for disassembly, the vertical plate 1 is provided with a hollow hole 323 on the rear groove wall of the corresponding buckle structure slot 32. When disassembly is required, the latch 31 is pushed inward through the hollow hole 323 on the outside of the vertical plate with the help of a tool, thereby releasing the latch 31 from the locking protrusion 33 and realizing the disassembly of the latch 31 relative to the slot 32.

[0025] In summary, the modular storage rack designed in this utility model consists of two vertical panels 1 on the left and right sides and multiple shelves 2. The two side walls of each shelf 2 are connected to the vertical panel 1 by at least one set of snap-fit ​​structures 3. Compared with the existing support rod structure, the above vertical panel 1 structure can not only ensure the connection strength between the components, but also effectively improve the support strength of the entire storage rack, thereby meeting the storage needs of heavier items in practice.

[0026] The rear side of the vertical plate 1 is bent to form a rear connecting plate 12. The rear connecting plate 12 is provided with a wall-mounting hole 121 that can be connected to a wall hook. The rear connecting plate 12 can further enhance the support strength of the vertical plate 1. At the same time, the wall-mounting hole 121 on it, combined with the hook on the wall, can realize the wall-mounting of the entire storage rack.

[0027] The front side of the vertical plate 1 is bent to form a front edge 11, which can also enhance the support strength of the vertical plate 1.

[0028] Considering the need for dust prevention, a bottom plate 4 can be provided between the bottoms of the two vertical plates 1, and a top plate 5 can be provided between the tops of the two vertical plates 1. A retrieval opening is formed between the bottom plate 4, the top plate 5 and the front edge 11 of the two vertical plates 1, and an openable and closable cabinet door 6 is provided on the retrieval opening.

[0029] The cabinet door 6 can be configured as a single door or a double door as needed. Each of the top and bottom sides of the cabinet door 6 is provided with a connecting shaft 61, and the two connecting shafts 61 are movably connected to the shaft holes on the top plate 6 and the bottom plate 4, respectively.

[0030] To facilitate opening, the cabinet door 6 is equipped with a handle 62.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
