Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a multi-purpose shelving. Background Technology

[0002] In daily life, shelving units are commonly used as storage tools in homes, offices, and other settings, especially in bathrooms and kitchens, where they serve the important function of storing toiletries, kitchen utensils, and condiments. With the increasing demand for more refined use of living space, users have higher requirements for the practicality, flexibility, and spatial adaptability of shelving units. However, existing shelving units still have many limitations in practical use. Most storage shelves on the market today are fixed structures, meaning their frames and shelf positions cannot be adjusted once installed. The fixed shelf spacing makes it difficult to accommodate items of varying heights, such as shampoos, shower gels, and skincare products in bathrooms. This often results in items not being able to stand upright due to insufficient shelf spacing, or wasting space due to excessive spacing. Furthermore, fixed shelves cannot be folded away when not in use, continuously occupying wall or floor space. In small bathrooms and other confined areas, this can lead to overcrowding and hinder daily convenience. While some adjustable shelves offer shelf spacing adjustment, their complex structures often rely on bolts or snap-fit ​​connections, making operation cumbersome and unstable. During adjustment, shelves are prone to loosening and wobbling, and under load, there's a risk of them falling off, compromising safety. Furthermore, the folding mechanism of these shelves is often poorly designed; even when folded, they require additional storage space, or folding requires disassembling multiple parts, increasing the user's burden.

[0003] Therefore, we propose a multi-purpose storage rack. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose storage rack to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-purpose storage rack, comprising: a fixed plate, slots, and a placement plate. A first support rod and a second support rod are rotatably connected to one side of the fixed plate, and a U-shaped rod is provided on one side of the fixed plate. One end of each of the two first support rods and the two second support rods is rotatably connected to the U-shaped rod. Slots are provided at equal intervals on the side of the fixed plate near the first support rod. Slots corresponding to the slots are provided at equal intervals on the inner side of the U-shaped rod. The placement plate is slidably installed between the slots and the slots. A storage groove for storing the placement plate is provided at the top of the fixed plate.

[0006] Preferably, a groove is provided on one side of the U-shaped rod, and an extrusion plate is slidably connected to the inner wall of the groove. A bolt is threadedly connected to one side of the U-shaped rod, and one end of the bolt is rotatably connected to one side of the extrusion plate. The groove communicates with several of the aforementioned grooves.

[0007] Preferably, a connecting groove is provided on one side of the fixing plate, a slide rod is fixedly connected to the inner wall of the connecting groove, an ear block is slidably connected to the inner wall of the connecting groove, the ear block is slidably connected to the slide rod, and a spring is sleeved on the outer wall of the slide rod, with both ends of the spring fixedly connected to one side of the connecting groove respectively.

[0008] Preferably, a square through hole is provided at one end of the ear block, and a square protrusion is fixedly connected at the connection between the first support rod and the fixing plate, and the square through hole and the square protrusion are slidably connected.

[0009] Preferably, the bottom end of the fixing plate is symmetrically fixed with pads, and the two pads are in contact with the bottom end of the second support rod.

[0010] Preferably, one end of each of the two second support rods has a hanging groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Improve space utilization efficiency and adapt to small scenarios The shelving unit employs a parallelogram linkage structure consisting of a first support rod, a second support rod, and a U-shaped rod. Combined with a locking mechanism using lugs and square protrusions, it achieves convenient folding and unfolding. When not in use, the U-shaped rod can be folded to fit snugly against the fixed panel, significantly reducing its space occupation. This is especially suitable for small areas such as small bathrooms, avoiding the cramped feeling caused by the continuous space occupation of traditional fixed shelving units. Simultaneously, the storage slot at the top of the fixed panel can centrally store unused shelves, further reducing space waste caused by scattered storage and improving the overall tidiness of the living space. II. Enhance adjustment flexibility to meet diverse storage needs By using the slots of the fixed plate and the sliding grooves of the U-shaped rod, the placement plate can slide along both and be inserted into the slots at different positions, allowing for flexible adjustment of the spacing between adjacent placement plates. This design breaks through the limitations of traditional fixed shelves with fixed shelf spacing. Users can freely adjust the spacing according to the height differences of items such as bathroom toiletries and kitchen condiments. This avoids the problem of items not being able to stand upright due to insufficient shelf spacing, and also prevents the space waste caused by excessive shelf spacing, significantly improving the shelf's adaptability to items of different sizes. III. Optimize structural stability and ensure safe use. The shelving unit features a multi-layered stability design: a pad at the bottom of the fixed plate and a second support rod together form a bottom support point, distributing the load and preventing the shelving unit from tilting outwards; the rigid fit between the ear blocks and the square protrusions securely locks the parallelogram structure in the unfolded state, preventing the frame from wobbling under load; and the bolts on the U-shaped rod, in conjunction with the compression plate, use friction to fix the position of the shelf, preventing it from sliding when retrieving items. The synergistic effect of these multiple stabilizing structures effectively solves the problems of traditional adjustable shelving units being prone to loosening and falling off under load, ensuring safety and reliability during use.

[0017] Working principle: I. Basic Structure and Installation Fixing Core framework components: The basic structure of the shelving unit includes a fixed plate 1, first support rods 2, second support rods 3, and a U-shaped rod 4. The fixed plate is fixed to the wall with screws, serving as the load-bearing foundation for the entire shelving unit. The two first support rods and two second support rods are rotatably connected to the fixed plate and the U-shaped rod at both ends, forming a parallelogram linkage structure. The characteristic of this structure is that when subjected to force, each rod can rotate around the hinge point, allowing the U-shaped rod to move parallel to the fixed plate, providing a basis for folding and unfolding functions.

[0018] Initial support assistance: The pads 18, which are symmetrically fixed at the bottom of the fixed plate, contact the bottom of the second support rod when the shelf is unfolded, forming a bottom support point together with the second support rod, preventing the shelf from tilting outward due to the load and enhancing the overall stability.

[0019] II. Deployment and Locking Mechanism Expand operation: When the shelf is needed, pull the U-shaped rod 4. The first support rod 2 and the second support rod 3 in the parallelogram structure will rotate outward around the hinge point with the fixed plate, moving the U-shaped rod away from the wall. As the rotation angle increases, the shelf gradually unfolds until it reaches a suitable angle for placing items. At this point, the U-shaped rod and the fixed plate maintain a parallel distance.

[0020] State locking principle: The locking mechanism in the unfolded state relies on the engagement of the lug 14, the square through hole 16, and the square protrusion 17. A sliding rod 13 is provided in the connecting groove 12 on one side of the fixed plate. The lug 14 is fitted on the sliding rod and can slide along it. The two ends of the spring 15 outside the sliding rod are connected to the inner wall of the connecting groove and the lug respectively. Under normal conditions, the spring pushes the lug close to the connection between the first support rod and the fixed plate.

[0021] A square protrusion 17 is fixed at the hinge of the first support rod and the fixed plate. The square through hole 16 at one end of the ear block matches the size of the square protrusion. When the shelf is unfolded into place, the spring pushes the ear block to make the square through hole fit into the square protrusion. The rigid fit of the square structure restricts the rotation of the first support rod, thereby locking the entire parallelogram structure and ensuring that the shelf does not shake or fold when bearing weight.

[0022] III. Adjustment and Fixing of the Placement Board Spacing adjustment function: Slots 5 are evenly spaced on one side of the fixed plate near the first support rod, and corresponding grooves 6 are formed on the inner side of the U-shaped rod. The two ends of the placement plate 7 are inserted into the slots and grooves respectively and can slide along them. Since the slots and grooves are evenly distributed, users can insert the placement plate into the slots and grooves at different positions according to the height of toiletries such as shampoo and shower gel, flexibly adjusting the vertical spacing between adjacent placement plates to meet the storage needs of items of different heights.

[0023] Position fixing mechanism: The groove 9 on one side of the U-shaped rod is connected to the slide 6, and the extrusion plate 10 in the groove is driven by the bolt 11. After the placement plate is adjusted to the target position, the bolt is turned, and the bolt pushes the extrusion plate to slide in the groove. The extrusion plate is in close contact with the edge of the placement plate in the slide, and the position of the placement plate is fixed by friction to prevent the placement plate from sliding due to the removal and placement of items during use.

[0024] IV. Folding Storage Mechanism When the shelf is not in use, it can be folded and stored away using the following steps to save space: Unlocking operation: Pull the ear block 14 to overcome the elastic force of the spring 15, so that the ear block slides along the slide bar 13 away from the square protrusion 17 until the square through hole 16 is completely disengaged from the square protrusion, thereby releasing the rotation restriction on the first support rod 2.

[0025] Folding linkage: Push the U-shaped rod 4 towards the fixed plate 1. At this time, the first and second support rods rotate inward around the hinge point, and the parallelogram structure retracts. As the rotation continues, the U-shaped rod gradually approaches the fixed plate until it is in contact with the side of the fixed plate, completing the folding.

[0026] Folding and locking: After folding into place, release the ear block 14, the spring 15 returns to its original position and pushes the ear block to move, so that the square through hole 16 slides and connects with the square protrusion 17 again, locking the folded state and preventing the shelf from being accidentally unfolded.

[0027] Placement board storage: Before folding, the placement board 7 can be removed from the slot 5 and slide 6 and placed into the storage slot 8 at the top of the fixed board to achieve centralized storage of parts and further save space.

[0028] V. Additional Functions: Suspension Extension The hanging slot 19 at one end of the second support rod 3 can be used to hang small items such as towels, bath balls, and bath towels, expanding the use scenarios of the shelf and improving its practicality without taking up space on the shelf.
