Description

Technical Field

[0001] This utility model belongs to the field of kitchen utensils, specifically a storage rack. Background Technology

[0002] In the realm of kitchenware, storage racks are primarily used to drain water from washed dishes and utensils, preventing water accumulation and bacterial growth. Currently, the mainstream storage racks on the market include stainless steel wire baskets and roll-up racks, but both have significant drawbacks. Stainless steel wire basket racks use a fixed wire structure, which, while durable, takes up a lot of space and cannot accommodate tableware of different shapes. Roll-up racks, while allowing for easy storage, require stacking dishes, resulting in incomplete drainage and increased risk of damage from collisions. These designs are insufficient in terms of space utilization and functionality, failing to meet the modern kitchen's demands for efficient drainage and flexible storage.

[0003] In summary, the main problems with existing kitchen storage racks are concentrated in three aspects: first, low space utilization, as the fixed structure cannot be folded or retracted, occupying countertop space for extended periods; second, poor versatility, making it difficult to adapt to tableware of different sizes and shapes; and third, poor drainage, as stacking or fixed grid designs affect water evaporation efficiency. Especially for small kitchens, the large size and fixed structure of traditional storage racks severely limit their flexibility, while roll-up racks lack the load-bearing capacity and stability needed for daily use. Therefore, the market urgently needs a new type of storage rack that can improve space utilization through a foldable design while ensuring stable load-bearing capacity and good drainage. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of existing shelves not being able to balance space utilization, versatility and stability, and to provide a shelf that meets these requirements.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The shelf includes a first shelf, a second shelf, a third shelf, and a connecting structure. The second and third shelves are provided with positioning notches. The opposite sides of the second shelf are connected to one side of the first or third shelf through the connecting structure. When the other side of the first shelf abuts against the other side of the third shelf, the first, second, and third shelves form a triangular upright state. The positioning notches are spliced ​​together to form a placement structure for placing tableware.

[0007] This utility model provides a deformable storage rack with a three-component modular design. Through the combination of the first, second, and third storage components and connecting structures, it achieves free switching between at least two states. Its core innovation lies in: 1) In the triangular upright state, the three components support each other to form a stable triangular structure, and the positioning notches combine in a preset manner to form specific tableware storage spaces (i.e., placement structures); 2) In the flat unfolded state, the components lay flat to form a low-height draining platform and can also form other storage spaces. This design breaks through the single-function limitations of traditional storage racks, allowing the product to be flexibly adjusted according to actual usage scenarios, fully embodying the design concept of "one item, multiple uses." Through simple form transformation, it can meet the differentiated needs of different families regarding storage rack capacity, space occupation, and storage efficiency.

[0008] Furthermore, the first, second, and third storage components each include a drain panel and connecting portions disposed on opposite sides of the drain panel, with the connecting structure disposed on the connecting portions. Thus, in the unfolded state, the connecting portions act as bottom supports for the drain panel; in the triangular upright state, the planar contact of each storage component increases the stress-bearing area, significantly improving the overall structural stability.

[0009] Furthermore, the connection structure includes a flexible connector and connecting holes. The connecting holes are located on the first, second, and third storage units, and the flexible connector connects two adjacent connecting holes. In this solution, the second storage unit is foldably (and relatively rotatable) connected to the first and third storage units via the flexible connector. The elastic properties of the flexible connector allow it to absorb deformation during daily use, avoiding plastic fatigue of plastic or metal parts and thus delaying aging. Compared to traditional rigid hinges, the flexible connector is less prone to wear or rust due to frequent folding, making it particularly suitable for humid kitchen environments. While ensuring the strength and functionality of the storage rack, it significantly improves folding smoothness, storage efficiency, and adaptability to different scenarios.

[0010] Furthermore, the flexible connector includes a first structural portion and a second structural portion symmetrically disposed on both sides of the first structural portion, and the connecting hole is sleeved on the second structural portion.

[0011] Furthermore, the connecting hole is an elongated hole, adapted to the length of the flexible connector. In this design, the equal-length fit between the flexible connector and the elongated hole ensures uniform tension distribution under stress, avoiding localized stress concentration caused by traditional circular connecting holes, and effectively preventing plastic deformation of the connector due to long-term use.

[0012] Furthermore, the positioning notches are spaced apart on the second and third storage components. The placement structure includes a first storage position and a second storage position. The positioning notches penetrate the side where the second and third storage components are connected, so that the positioning notches of the two components combine to form the first storage position in the unfolded state and combine to form the second storage position in the triangular upright state.

[0013] Furthermore, the first shelf is selectively folded to abut one of the upper or lower sides of the second shelf, and the third shelf is folded to abut the other side of the second shelf to form a folded state. This design allows the three shelves to be stacked vertically, compressing the shelf's surface area and making storage easier. When folded, the first shelf contacts the countertop through its connecting part, the second shelf folds to the top of the first shelf, and the third shelf folds to the top of the second shelf, so that their connecting parts abut against each other to form a hollow sandwich structure (at this time, the positioning notch of the third shelf is used to fix the tableware); of course, the third shelf can also be placed at the bottom, with the second and first shelves stacked in sequence.

[0014] Furthermore, the second and third shelves are arranged in a mirror-symmetric manner. This design enables the three shelves to form a stable isosceles triangular support structure in three triangular upright states, with the first shelf serving as the base support at the bottom, creating a deep, three-dimensional second storage space at the top of the triangular structure.

[0015] Furthermore, the shape of the first storage compartment matches the cross-sectional profile of the dish, allowing the dish to be inserted vertically and securely engaged.

[0016] Furthermore, the first placement component is provided with a positioning slot, the shape of which matches the cross-sectional profile of the bowl. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] See Figure 1-8 As shown, this utility model discloses a storage rack 1, which includes a first storage component 2, a second storage component 3, a third storage component 4, and a connecting structure. The second storage component 3 and the third storage component 4 are provided with positioning notches. The opposite sides of the second storage component 3 are connected to one side of the first storage component 2 and the third storage component 4 through the connecting structure. When the other side of the first storage component 2 abuts against the other side of the third storage component 4, the first storage component 2, the second storage component 3, and the third storage component 4 form a triangular upright state. The positioning notches are spliced ​​together to form a storage structure for placing tableware.

[0030] In one embodiment, to improve the stability of the placement and connection of the shelf 1, the first shelf 2, the second shelf 3, and the third shelf 4 include a drain panel 21 and connecting portions disposed on opposite sides of the drain panel 21, with the connecting structure disposed on the connecting portions. Thus, in the unfolded state, the connecting portions act as bottom supports for the drain panel 21; in the triangular upright state, the planar contact of each shelf increases the stress-bearing area, significantly improving the overall structural stability.

[0031] In one embodiment, the connecting structure includes a flexible connector 51 and connecting holes 54. The connecting holes 54 are disposed on the first shelf 2, the second shelf 3, and the third shelf 4, and the flexible connector 51 connects two adjacent connecting holes 54. In this solution, the second shelf 3 is foldably (and relatively rotatable) connected to the first and third shelves through the flexible connector 51. Furthermore, the elastic properties of the flexible connector 51 allow it to absorb deformation during daily use, avoiding plastic fatigue of plastic or metal parts and thus delaying aging. Compared to traditional rigid hinges, flexible components are less prone to wear or rust due to frequent folding, making them particularly suitable for humid kitchen environments. While ensuring the strength and functionality of the shelf 1, this significantly improves folding smoothness, storage efficiency, and adaptability to different scenarios.

[0032] In one embodiment, the flexible connector 51 includes a first structural portion 52 and a second structural portion 53 symmetrically disposed on both sides of the first structural portion 52, and the connecting hole 54 is sleeved on the second structural portion 53.

[0033] In one embodiment, the connecting hole 54 is an elongated hole, adapted to the length of the flexible connector 51. In this design, the equal-length fit between the flexible connector 51 and the elongated hole ensures uniform tension distribution under stress, avoiding localized stress concentration caused by traditional circular connecting holes 54, and effectively preventing plastic deformation of the connector due to long-term use.

[0034] In one embodiment, the positioning notches 33 are spaced apart on the second and third storage components 3 and 4, and the placement structure includes a first storage position 34 and a second storage position 35. The positioning notches 33 penetrate the side where the second and third storage components 3 and 4 are connected, so that the positioning notches 33 of the two components combine to form the first storage position 34 in the unfolded state and combine to form the second storage position 35 in the triangular upright state.

[0035] In one embodiment, the first storage element 2 is folded to selectively abut against one of the upper and lower sides of the second storage element 3, and the third storage element 4 is folded to align with the other side of the second storage element 3 to form a folded state.

[0036] In one embodiment, the second shelf 3 and the third shelf 4 are arranged in a mirror-symmetric manner. This design enables the three to form a stable isosceles triangular support structure in three triangular upright states, with the first shelf 1 serving as the base support at the bottom, creating a deep, three-dimensional second storage space 35 at the top of the triangular structure.

[0037] In one embodiment, the shape of the first receiving position 34 matches the cross-sectional profile of the dish, allowing the dish to be inserted vertically and securely engaged.

[0038] In one embodiment, the first placement component 2 is provided with a positioning slot 22, the shape of which matches the cross-sectional contour of the bowl.

[0039] The aforementioned connecting portion includes a first connecting portion 23 disposed on opposite sides of the first object holder 2, the first connecting portion 23 being disposed along the length direction of the first object holder 2.

[0040] The aforementioned connecting portion includes a second connecting portion 31 located on the side where the second placement member 3 and the third placement member 4 are connected and extending downward, the second connecting portion 31 being located between two adjacent second positioning notches 33, and a third connecting portion 32 located on the other side of the second placement member 3 and the third placement member 4.

[0041] This utility model's storage rack 1 uses a connecting structure to rotatably connect the second storage component 3 to one side of the first storage component 2 and the third storage component 4. When the free ends of the first storage component 2 and the third storage component 4 abut against each other, the three storage components together form a stable triangular vertical structure. At this time, the positioning notches on each storage component interlock to form a stable tableware placement platform. By separating the abutting ends and unfolding the storage components, it can be quickly converted into a low-height, flat unfolded state, realizing flexible switching between two usage modes. In the triangular vertical state, the three storage components form a rigid triangular support structure with excellent stability and anti-tipping performance, and the spliced ​​positioning notches can firmly fix the tableware. In the unfolded state, the overall height is significantly reduced, and the flat design greatly saves storage space. Each storage component can still independently use its positioning notch for tableware drainage. To optimize storage, the three storage components can be stacked vertically to form a folded state.

[0042] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
