[0015] In this embodiment, the upright frame 1 serves as the vertical support structure for the entire storage rack, providing the basic carrier for height adjustment of the upper movable storage component 3. The L-shaped base frame 13 bears the load of the lower movable storage box 2 and provides bottom support for the entire storage rack. Its symmetrical arrangement ensures the balance of the bottom of the storage rack and guarantees the overall stability of the storage rack. The upright frame adjustment hole 11 is used to cooperate with the connector snap-fit ​​part 311 and connector bending part 312 of the upper movable storage component 3 to realize flexible adjustment of the height of the upper storage box body 32, so as to adapt to the storage needs of different heights under the sink and different sizes of items. The lower movable storage box 2 is used to store various items in the kitchen, such as cookware, cleaning supplies, etc., providing a large storage space. The storage box connecting plate 31 of the upper movable storage component 3 is the bridge connecting the upright frame 1 and the storage box body 32, through the connector snap-fit ​​part 31 on it. 1. The connecting bending part 312, connecting hook plate 313, and connecting protrusion 314 achieve a stable connection with the stand 1 and the storage box body 32. The connecting snap-fit ​​part 311 and the connecting bending part 312 snap-fit ​​with the stand adjustment hole 11 to fix the storage box connecting plate 31 on the stand 1, thereby fixing the storage box body 32. The connecting hook plate 313 snaps into the hook plate mounting groove 321 of the storage box body 32 to fix the storage box body 32 laterally and prevent it from wobbling. The connecting protrusion 314 snaps into the protrusion snap-fit ​​groove 322 of the storage box body 32 to further enhance the stability of the connection between the storage box connecting plate 31 and the storage box body 32.

[0017] Effect: Through layered design, the three-dimensional space under the sink is fully utilized. The design of the stand adjustment hole 11 allows the height of the upper movable storage component 3 to be adjusted according to actual needs. The installation process requires no complicated tools and is simple and convenient to operate. Users can quickly complete the installation according to their own needs. The storage box connecting plate 31 is connected to the stand 1 by the connector snap-fit ​​part 311 and the connector bending part 312. It is connected to the storage box body 32 by the connector hook plate 313 and the connector protrusion 314, which are respectively snapped into the hook plate mounting groove 321 and the protrusion snap-fit ​​groove 322. The multi-snap structure ensures the stability of the connection. Even if heavy items are placed, they are not easy to loosen or fall off. The second storage box hollow hole 323 at the bottom of the storage box body 32 allows water inside the box to drain in time, keeping the items dry. The dry design reduces bacterial growth, which is beneficial for item preservation. It facilitates packaging, avoids the use of screws that take up space in the box, and is a single unit after assembly, making it difficult to disassemble. This reduces transportation costs. The modular design of each component allows for quick disassembly and assembly, enabling compact stacking during packaging and reducing packaging volume, which is convenient for logistics and transportation. The entire process uses a snap-fit ​​structure, eliminating the need for screw fixation and preventing screw installation from taking up internal space, thus maximizing storage space utilization. After assembly, the components form a stable whole through multiple snap-fit ​​connections, making it difficult to disassemble without professional operation. This ensures structural stability during use and reduces the risk of damage due to accidental disassembly. The small size and even weight distribution after disassembly allow for bulk transportation, reducing the unit transportation cost of the product and enhancing its market competitiveness.

[0018] Specifically, the upper surfaces of the two sets of L-shaped base frames 13 are movably snapped with support frames 15. The support frames 15 are integrally formed by the upper frame side plate 152, the lower frame plate 151 and the middle plate. The length of the lower frame plate 151 on both sides is shortened inside the upper frame side plate 152. The support frames 15 are movably snapped with on both sides of the two L-shaped base frames 13. The top of the two uprights 1 are bolted with top crossbeams 12. The bottom of the L-shaped base frame 13 is equipped with suction cup seats 14, which are threadedly connected to the L-shaped base frame 13.

[0019] In this embodiment, the support frame 15, through the integrated structure of the upper frame side plate 152 and the lower frame clamping plate 151, provides a stable placement platform for the lower movable storage box 2, ensuring that the lower storage box will not tilt or fall during use. It is movably clamped to both sides of the two sets of L-shaped base frames 13, enabling quick assembly and disassembly with the L-shaped base frames 13, facilitating the installation, maintenance, and component replacement of the storage rack. The upper frame side plate 152 forms a protective structure on both sides of the support frame 15, preventing the lower movable storage box 2 from sliding off the sides, while also enhancing the overall structural strength of the support frame 15. Since the lengths of the lower frame clamping plate 151 are shortened to its interior, space is provided for the clamping of the lower frame clamping plate 151 and the L-shaped base frame 13, ensuring a reasonable layout of the clamping structure. The lower frame clamping plate 151 and the L-shaped base frame 13... The movable snap-fit ​​joints on both sides of the frame 13 are key components for connecting the support frame 15 and the L-shaped base frame 13. This snap-fit ​​method allows for initial fixation without additional fasteners. The top crossbeam 12 is bolted to the top of the two uprights 1, connecting them into a whole and enhancing the structural stability of the top of the storage rack, preventing the uprights 1 from shaking or deforming during use. The suction cup base 14 uses the suction force of the suction cup to firmly fix the L-shaped base frame 13 to the ground, preventing the storage rack from sliding during use and increasing the safety of the storage rack. The threaded connection allows for the installation, removal, or replacement of the suction cup base 14 without additional tools, making it simple to operate and providing a stronger connection than snap-fit ​​structures. It can withstand the weight of the storage rack and its contents for a long time, ensuring stability during use.

[0020] Specifically, the adjustment holes 11 of the upright frame are set at equal intervals along the height direction of the upright frame 1, and the distance between adjacent adjustment holes 11 is 3-5cm.

[0021] In this embodiment, the equidistant design ensures that the adjustment process of the upper movable storage component 3 is uniform and controllable. The 3-5cm spacing not only meets the storage needs of items of different heights, tall and short bottles and jars, and small kitchen utensils, but also avoids insufficient adjustment precision due to excessive spacing, or cumbersome adjustment operation due to excessive spacing. Through the cooperation of the connector snap-fit ​​part 311 and the connector bending part 312 with the storage box connecting plate 31, the installation height of the upper storage box body 32 can be quickly switched according to the height of the space under the sink, the distribution of pipes, or the user's usage habits, thereby improving the adaptability of the storage rack to different sink cabinet environments.

[0022] Specifically, the bottom of the lower movable storage box 2 is provided with a first storage box perforation 21. Both the first storage box perforation 21 and the second storage box perforation 323 are elongated perforations. The width of the lower movable storage box 2 is greater than the width of the storage box body 32. Both the lower movable storage box 2 and the upper movable storage component 3 have the first storage box perforation 21 at their bottom. The elongated perforation of the first storage box perforation 21 has a larger permeable area, which can quickly drain residual moisture from the surface of items in the lower movable storage box 2, such as pots, cleaning tools, and larger bottles and jars. At the same time, it promotes air circulation, prevents the box from becoming damp and breeding bacteria and producing odors, and keeps the contents clean. To ensure items stay dry and clean, both the upper and lower storage boxes feature a long, perforated design, creating a continuous ventilation channel. This allows air to circulate between the upper and lower layers within the enclosed space under the sink, further enhancing overall drainage and moisture-proofing. This prevents moisture buildup in the lower layer from affecting items on the upper layer. The width of the lower movable storage box 2 is greater than the width of the main storage box 32. This width difference aligns with the classification and storage logic of "larger items on the lower layer, smaller items on the upper layer." The wider lower layer can accommodate larger items such as pots, large cleaning buckets, and large-capacity storage containers, while the narrower upper storage box 32 is suitable for smaller items such as condiment bottles, tableware, and small tools, achieving precise space allocation.

[0023] Specifically, both the lower movable storage box 2 and the upper movable storage component 3 are made of galvanized steel sheet.

[0024] In this embodiment, the overall structure and the upper and lower storage layers are made of galvanized steel sheet. Galvanized steel sheet has excellent structural strength and rigidity. Compared with plastic and ordinary sheet materials, it can withstand greater weight and is not prone to bending, deformation or breakage after long-term use, effectively extending the service life of the storage rack. It is suitable for high-frequency use scenarios in the kitchen. The galvanized layer can form a dense protective film, which isolates moisture, acid and alkali media from contact with the steel plate substrate, preventing rust and corrosion. This solves the problem that ordinary metal materials are easily damaged in humid environments, ensuring that the storage box is clean and durable for a long time.

[0025] Example 2 Please refer to Figure 6 As shown, the other parts of this embodiment are the same as those of Embodiment 1. The difference is that a non-perforated storage box 4 is provided in a pull-out manner between the support frames 15.

[0026] A non-perforated storage box 4 is provided between the support frames 15 via a pull-out design.

[0027] The perforated storage box 4 is suitable for large items that do not require drainage. The complete bottom structure without perforations can distribute the pressure of heavy objects and increase the load-bearing capacity of the lower layer. It can stably place heavy pots and pans, large-capacity bottles and jars, etc., and is not prone to deformation due to excessive local stress. At the same time, the closed bottom can prevent ground moisture from directly penetrating, thus protecting large items that need moisture protection. The upper layer focuses on "ventilation and drainage", while the lower layer focuses on "load-bearing and sealing", realizing the functional division of "ventilation for small items and stability for large items". It is suitable for the storage needs of different types of kitchen items. Depending on the user's needs, storage boxes with or without perforations can be selected. Consumers can choose to purchase either one. If both are purchased, they can be stacked for packaging and transportation to reduce transportation costs.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
