Description

Technical Field

[0001] This utility model relates to the field of furniture equipment technology, and in particular to a rotating storage rack. Background Technology

[0002] Multi-tiered storage shelves are common storage devices in daily life, widely used in homes, offices, warehouses, and other settings. Traditional storage shelves typically use a fixed shelf structure. While simple and inexpensive, in actual use, especially when storing many items or when the shelf is deep, it is very inconvenient for users to retrieve items placed inside the shelves or in corners. Often, they need to move items in front of them to reach them. This not only reduces storage efficiency but also makes it difficult to effectively utilize the internal space of the shelf.

[0003] Most multi-tiered storage shelves on the market are currently fixed structures, with each shelf arranged in parallel and unable to rotate. While this design offers some advantages in space utilization, in actual use, users need to bend over or stand on tiptoe to access items on different shelves, especially when storing items on higher or lower shelves, which is inconvenient and can easily cause physical fatigue. In recent years, as people's demands for convenience have increased, some rotating storage shelves have begun to appear, but most of them use a whole-unit rotating design, unable to rotate individual shelves independently. This means that the entire storage shelf still needs to be moved to retrieve items, resulting in a poor user experience.

[0004] In existing technologies, the following solutions are commonly used to address the inconvenience of accessing multi-layer storage shelves: First, increase the spacing between shelves to make each shelf more spacious and easier for users to reach for items. However, this solution significantly reduces the shelf's capacity. Second, add sliding rails or drawers to the sides of the shelf for lateral sliding access. However, this solution increases structural complexity and the rails are prone to wear. Third, adopt an overall rotating design, using a base motor to drive the entire shelf to rotate. However, this solution is costly, and all items move together during rotation, making it difficult to accurately locate the target item.

[0005] The main drawback of existing technology is that it cannot achieve independent rotation of a single-layer shelf, which means that when you want to take out an item, you still have to move the whole shelf or bend over to operate it, which is inconvenient. At the same time, increasing the spacing between layers or adding sliding rails will sacrifice storage space or increase structural complexity, and the overall rotation design is costly and energy-intensive.

[0006] Therefore, this utility model proposes a rotating storage rack to address the shortcomings of the prior art. Summary of the Invention

[0007] To overcome the above shortcomings, this utility model provides a rotating storage rack, which aims to improve the problems of inconvenience in retrieving items from fixed storage racks and the high cost and complex operation of overall rotating storage racks in the prior art.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a rotating storage rack, comprising: a column and a plurality of rotating storage baskets rotatably connected to the column, and further comprising: Rotating components and limiting components; The rotating assembly includes a sleeve, a bearing, an L-shaped rotating rod, a fixing block, a limiting block, and a torsion spring. The sleeve is fixedly connected to the outer wall of the column. The L-shaped rotating rod passes through the sleeve and is rotatably connected to the sleeve through the bearing. One end of the L-shaped rotating rod is fixedly connected to the rotating storage basket through the fixing block. The limiting component includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to the outer wall of the column, and the second connecting block is fixedly connected to the side wall of the rotating storage basket.

[0009] Preferably, the torsion spring is sleeved on the outer wall of the L-shaped rotating rod, and the two ends of the torsion spring are respectively connected to the inner wall of the L-shaped rotating rod and the sleeve.

[0010] Preferably, the limiting block is fixedly connected to the end of the L-shaped rotating rod away from the rotating basket, and is used to abut against the sleeve to limit the axial displacement of the L-shaped rotating rod.

[0011] Preferably, the first connecting block is provided with a first magnet inside, and the second connecting block is provided with a second magnet inside. The first magnet and the second magnet attract each other when the rotating basket rotates to a predetermined position.

[0012] Preferably, the bearing is fixed inside the sleeve, and the L-shaped rotating rod passes through the inner ring of the bearing.

[0013] Preferably, the rotating storage rack further includes at least another upright and a crossbeam, the crossbeam being horizontally connected between the upright and the other upright.

[0014] Preferably, the rotating storage rack further includes a top storage basket, which is fixedly connected to the top side wall of the column.

[0015] Preferably, the rotating storage rack further includes a bottom storage basket, which is fixedly connected to the bottom side wall of the column.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by independently setting a rotating component connected to the column for each rotating storage basket, it is possible to rotate horizontally independently, which solves the problems of inconvenience in taking out items from the fixed storage rack and the high cost and complicated operation of the overall rotating storage rack in the prior art. It achieves the effect of making it convenient for users to accurately and quickly take out target items and improving the flexibility of space utilization.

[0017] 2. This utility model solves the problem that rotating structures with reset functions may accidentally rotate due to external force or spring rebound when retrieving items by setting a limiting component consisting of a first magnet and a second magnet on the rotating storage basket and the upright column. The magnetic attraction is used for positioning, thus achieving the effect of automatically and reliably locking the rotating storage basket after rotation, thereby significantly improving the safety and stability of use.

[0020] Reference Figures 1-5 This utility model provides a rotating storage rack, which aims to solve the problems of inconvenience in retrieving items, complex operation and high cost of multi-layer storage racks in the prior art.

[0021] Specifically, it includes a column 1 and multiple rotating storage baskets 4 rotatably connected to the column 1. The column 1 serves as the mounting and support base for the entire device, providing an installation interface for the rotating storage baskets 4 and other components. The rotating storage baskets 4 are used to carry items and realize independent rotating retrieval functions.

[0022] It also includes a rotating component 6 and a limiting component 7, thereby realizing the independent rotation, automatic reset and positioning of the rotating storage basket 4. The rotating component 6 includes a sleeve 601, a bearing 602, an L-shaped rotating rod 603, a fixing block 604, a limiting block 605 and a torsion spring 606. The sleeve 601 is fixedly connected to the outer wall of the column 1 by welding or bolts. The rod part of the L-shaped rotating rod 603 passes through the internal cavity of the sleeve 601 and is rotatably connected to the sleeve 601 by the bearing 602 set inside the sleeve 601. One end of the L-shaped rotating rod 603 is fixedly connected to the outer wall of the rotating storage basket 4 by means of the fixing block 604, so that the tension applied to the rotating storage basket 4 can be effectively transmitted to the L-shaped rotating rod 603, driving the L-shaped rotating rod 603 to rotate around its own axis.

[0023] Meanwhile, the limiting component 7 includes a first connecting block 701 and a second connecting block 702. The first connecting block 701 is fixedly connected to the outer wall of the column 1, and its specific position corresponds to the target position after the rotating storage basket 4 is rotated. The second connecting block 702 is fixedly connected to the side wall of the rotating storage basket 4. When the rotating storage basket 4 rotates, the second connecting block 702 moves synchronously with the rotating storage basket 4 and eventually interacts with the first connecting block 701 to complete the positioning and locking of the rotating storage basket 4.

[0024] To enable the automatic reset function of the rotating basket 4 after the item retrieval operation is completed, a torsion spring 606 is sleeved on the outer wall of the L-shaped rotating rod 603 and located inside the sleeve 601. One end of the torsion spring 606 is fixedly connected to the rod body of the L-shaped rotating rod 603, and the other end is fixedly connected to the inner wall of the sleeve 601. When the L-shaped rotating rod 603 rotates under the action of external force, the torsion spring 606 undergoes torsional deformation and stores mechanical energy in the form of elastic potential energy. Once the external force is removed, the stored elastic potential energy is released, driving the L-shaped rotating rod 603 to rotate in the opposite direction, thereby causing the rotating basket 4 to automatically return to the initial position.

[0025] To ensure smooth rotation and low friction of the L-shaped rotating rod 603 inside the sleeve 601, the bearing 602 is fixed inside the sleeve 601 by interference fit or adhesive bonding. The rod body of the L-shaped rotating rod 603 passes through the inner ring of the bearing 602, and the outer ring of the bearing 602 is fixed to the inner wall of the sleeve 601. The rod body of the L-shaped rotating rod 603 and the inner ring of the bearing 602 are in a rotational fit, and rolling friction is used instead of sliding friction, which greatly reduces the rotational resistance.

[0026] To prevent the L-shaped rotating rod 603 from shifting and coming out of the sleeve 601 when rotating or subjected to unexpected axial tension, thereby ensuring the stability and safety of the overall structure of the rotating assembly 6, a limiting block 605 is fixedly connected to the end of the L-shaped rotating rod 603 away from the rotating basket 4 by means of threaded connection or pin connection. The radial dimension of the limiting block 605 is larger than the inner diameter of the through hole of the sleeve 601, and it is used to abut against the end face of the sleeve 601 or the end face of the bearing 602 in the axial direction, thereby limiting the axial displacement of the L-shaped rotating rod 603 and ensuring that the L-shaped rotating rod 603 always remains in the preset working position.

[0027] In order to reliably lock the rotating storage basket 4 after it has rotated to the correct position and prevent it from accidentally resetting due to the rebound force of the torsion spring 606 or external disturbance, a first magnet 703 is provided inside the first connecting block 701, and a second magnet 704 is provided inside the second connecting block 702. When the rotating storage basket 4 rotates to a predetermined position under the action of an external force, for example, when it rotates 90 degrees, the second connecting block 702, which moves with the rotating storage basket 4, moves to the vicinity of the first connecting block 701 fixed on the column 1. At this time, the opposite magnetic poles of the first magnet 703 and the second magnet 704 face each other, generating a sufficiently strong magnetic attraction, which attracts the second connecting block 702 and fixes it to the first connecting block 701, thereby firmly locking the rotating storage basket 4 in the predetermined open position.

[0028] To further increase the storage space of the entire storage rack, the top storage basket 3 is fixedly connected to the top side wall of the column 1 by bolts or snaps, and the bottom storage basket 5 is also fixedly connected to the bottom side wall of the column 1 by bolts or snaps. The top storage basket 3 and the bottom storage basket 5 do not have a rotating function and can be used to store items that are not frequently used or are large in size, thus complementing the function of the rotating storage basket 4.

[0029] It also includes at least another column 1 and a crossbeam 2. The crossbeam 2 is a rod-shaped or plate-shaped structure. The two ends of the crossbeam 2 are fixedly connected to the initial column 1 and another column 1, respectively. The multiple columns 1 and the crossbeam 2 together form a more stable frame structure, which significantly improves the overturning resistance and load-bearing capacity of the entire device.

[0030] Working principle: When in use, the upright 1 is the supporting component of the entire storage rack. The upright 1 is vertically fixed to the ground, and the crossbeam 2 is horizontally connected between the upright 1. The top side wall of the upright 1 is fixed with a top storage basket 3, and the bottom side wall of the upright 1 is fixed with a bottom storage basket 5. Multiple rotatable rotating storage baskets 4 are set in the middle of the upright 1. The rotating component 6 allows the adjacent rotating storage baskets 4 to rotate left and right alternately, which makes it convenient for users to take out items, while avoiding the high cost and inconvenience of operation caused by overall rotation. After rotation, the baskets are fixed by the limiting component 7.

[0031] When the rotating basket 4 rotates alternately left and right, pulling the rotating basket 4 to one side causes the rotating basket 4, which is fixed to the outer wall of the rotating basket 4, to transmit the rotational force to the L-shaped rotating rod 603, causing the L-shaped rotating rod 603 to rotate inside the sleeve 601. The sleeve 601 is fixed to the outer wall of the column 1. When the L-shaped rotating rod 603 rotates, its rotational force causes the torsion spring 606, which is sleeved on the outer wall of the L-shaped rotating rod 603, to store elastic potential energy. One end of the torsion spring 606 is fixed inside the L-shaped rotating rod 603, and the other end of the torsion spring 606 is fixed to the inner wall of the sleeve 601. At this time, the outer wall of the L-shaped rotating rod 603 is fixed to the sleeve 601. The bearing 602 inside the sleeve 601 rotates, while the limiting block 605 fixed to one end of the L-shaped rotating rod 603 provides a limit to prevent the L-shaped rotating rod 603 from dislodging from the sleeve 601. By pulling the rotating storage basket 4, the cooperation of the fixing block 604, the L-shaped rotating rod 603, the limiting block 605 and the torsion spring 606 realizes the rotation function of the rotating storage basket 4, and the torsion spring 606 realizes automatic reset. This realizes that each rotating storage basket 4 can rotate independently, which makes it convenient for users to accurately take out the target items. The design of the adjacent rotating storage baskets 4 rotating left and right alternately avoids the high cost and inconvenience of overall rotation.

[0032] When fixing the rotated storage basket 4, after the rotating storage basket 4 rotates 90 degrees, a second connecting block 702 fixed to its side wall is provided with a 703 inside. At this time, a second magnet 704 is also provided inside the first connecting block 701 fixed to the outer wall of the column 1. At this time, 703 and the second magnet 704 will come into contact and produce a magnetic attraction effect, thereby realizing that the rotated storage basket 4 can be automatically locked in position to prevent accidental rotation due to the elasticity of the torsion spring 606 when taking out items.
