[0002] As the demands for space utilization and flexibility continue to rise in the fields of home, office, and commercial display, the versatility of shelving as a basic storage tool is receiving increasing attention.
[0003] Most storage racks on the market have fixed shelves (placement boards) with non-adjustable shelf heights, making them unsuitable for storing items of different heights and often resulting in wasted space or inconvenient storage. While some storage racks allow for manual shelf height adjustment via bolts or clips, the adjustment process is usually cumbersome, requires tools, and is difficult to quickly return to its original position after adjustment, leading to a poor user experience.
[0004] There is an urgent need for a storage rack that can quickly, flexibly, and intuitively adjust the placement space of each layer and remain stable under different conditions. Summary of the Invention
[0005] The purpose of this invention is to provide a felt storage rack with adjustable placement space, which allows for quick, flexible, and intuitive adjustment of the placement space on each shelf.
[0006] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a base; the upper end of the base is detachably provided with a vertically upward extending part, and multiple placement plates are rotatably provided on the side wall of the extending part, evenly arranged along the extending direction of the extending part; the side wall of the extending part is also provided with a lifting assembly corresponding to each placement plate and used to fix the placement plate in a horizontal position. The lifting assembly is located above the corresponding placement plate. The lifting assembly includes a mounting block, a rotating roller, a drive handle, a ratchet, a pawl, and a pull rope. The mounting block is fixedly provided with a rotating groove that allows the rotating roller to rotate. One end of the pull rope is detachably fixedly connected to the rotating roller, and the other end of the pull rope is detachably fixedly connected to the placement plate; both ends of the rotating roller are rotatably arranged in the rotating groove and extend out of the rotating groove. One end of the rotating roller is fixedly connected to the center of the ratchet, and the other end of the rotating roller... The end is fixedly connected to the drive handle; one end of the rotating rod is fixedly connected to the pawl, and the other end of the rotating rod is rotatably mounted on the outer wall of the mounting block. A torsion spring is sleeved on the rotating rod, one end of the torsion spring is fixedly mounted on the rotating rod, and the other end of the torsion spring is fixedly mounted on the mounting block. The pawl forms a one-way rotation limit engagement with the ratchet through the torsion force of the torsion spring. The rotating roller forms a one-way rotation through the one-way rotation limit engagement of the pawl and the ratchet. The pull rope is wound up on the rotating roller through the rotation of the rotating roller and the one-way rotation limit engagement of the pawl and the ratchet. The placement plate rotates towards the rotating roller through the winding of the pull rope to form a storage state. The pull rope is unwound through the rotation of the rotating roller and the pawl and the ratchet disengage from the one-way rotation limit engagement. The placement plate rotates away from the rotating roller through the unwound of the pull rope to form a horizontal unfolded state. A first placement space is formed between each placement plate and the base.
[0007] Furthermore, the groove wall of the rotating groove is provided with through holes corresponding to the two ends of the rotating roller. Bearings are installed in the through holes. The outer ring of the bearing is fixedly connected to the inner wall of the through hole, and the inner ring of the bearing is fixedly connected to the rotating roller. The rotating roller is rotatably mounted in the rotating groove through the bearings.
[0008] Furthermore, the extension includes a mounting plate and a connecting plate. Two mounting plates are provided, symmetrically arranged. A connecting plate is fixedly connected between opposite sides of the two symmetrically arranged mounting plates. Both sides of the connecting plate are fixedly connected to the two mounting plates respectively. The lower end of the connecting plate rests on the base. The placement plate and the lifting assembly are both located on the other side of the mounting plates. An installation space is formed between the connecting plate and the two mounting plates. Multiple support plates are fixedly arranged within the installation space, evenly arranged from the lower end to the upper end of the connecting plate. The sidewalls of each support plate are simultaneously fixedly connected to both the two mounting plates and the connecting plate. A second placement space for placing items is formed between the support plate closest to the base and the base, as well as between two adjacent support plates.
[0009] Furthermore, the base is provided with two first slots corresponding to the two mounting plates. A first block is formed between the bottom of the first slot and the bottom of the base. Each of the two mounting plates is provided with a second slot that can be inserted into the first block. A second block is formed between the bottom of the second slot and the mounting plate that can be inserted into the first slot. The two mounting plates are detachably mounted on the base through the insertion and engagement of the second slot with the first block and the first slot with the second block.
[0010] Furthermore, mounting blocks are symmetrically arranged on the mounting plate, and a first rotating shaft is fixedly provided on one end of the placement plate. The opposite side of the symmetrically arranged mounting blocks is provided with a first rotating groove that can form a rotating fit with the first rotating shaft. The placement plate is rotatably mounted on the mounting plate through the rotating fit between the first rotating shaft and the first rotating groove.
[0011] Furthermore, hooks are fixedly provided on both the placement plate and the rotating roller, and hooks that cooperate with the hooks are fixedly provided on both ends of the pull rope. The two ends of the pull rope are detachably fixedly connected to the placement plate and the rotating roller respectively through the cooperation of the hooks and hooks.
[0012] This utility model has the following positive effects: (1) Through multiple independently operable placement boards and their lifting components set on the side wall of the extension, users can choose to unfold some or all of the placement boards to a horizontal use state, or store the unnecessary placement boards and attach them to the extension, according to the actual height and volume of the stored items. This design greatly improves the space utilization rate, so that the same shelf can adapt to different storage needs from small items to large items.
[0013] (2) Each placement plate of this utility model is controlled by an independent lifting assembly. By rotating the drive handle, the rotating roller is driven to rewind the pull rope, and the placement plate can be easily pulled up to a horizontal unfolded state. The one-way rotation limiting mechanism composed of ratchet and pawl can effectively prevent the rotating roller from rotating in the opposite direction under the action of gravity or load, thereby ensuring that the placement plate is firmly locked in a horizontal state and has stable load bearing. When it is necessary to store it, simply disengage the pawl from the limiting engagement with the ratchet to release the rotating roller and allow the placement plate to fall smoothly.
[0014] (3) The base and the extension of this utility model are connected in a detachable manner, which makes the entire shelf easy to be disassembled into multiple parts, making it convenient for packaging, transportation and storage; at the same time, the extension itself can also be designed as a stable frame composed of a mounting plate, a connecting plate and a support plate, forming an additional second placement space inside, increasing the storage function.
[0015] (4) The pull rope, the placement plate, and the rotating roller in the lifting assembly of this utility model are detachably connected by hooks and rings, which makes it easy to replace the worn pull rope separately after long-term use and reduces maintenance costs; at the same time, the main transmission components such as the rotating roller are set by bearings, which ensures smooth operation and extends service life.

[0022] Mounting blocks 41212 are symmetrically arranged on the mounting plate 21. A first rotating shaft 31 is fixedly arranged on one end of the placement plate 3. A first rotating groove is provided on the opposite side of the symmetrically arranged mounting blocks 41212, which can form a rotating fit with the first rotating shaft 31. The placement plate 3 is rotatably arranged on the mounting plate 21 through the rotating fit between the first rotating shaft 31 and the first rotating groove.
[0023] Hooks 6 are fixedly provided on both the placement plate 3 and the rotating roller 42. Hooks 7 that cooperate with the hooks 6 are fixedly provided on both ends of the pull rope 46. The two ends of the pull rope 46 are detachably fixedly connected to the placement plate 3 and the rotating roller 42 respectively through the cooperation of the hooks 7 and the hooks 6.
[0024] The working principle of this utility model is as follows: When it is necessary to retract a certain layer of placement plate 3 to release vertical space, the user operates the corresponding lifting component 4; rotate the drive handle 43, which drives the rotating roller 42 fixedly connected to it to rotate synchronously; the rotating roller 42 is supported by bearings at both ends in the rotating groove 411 of the mounting block 41212, achieving smooth rotation. As the rotating roller 42 rotates, the pull rope 46 is wound up and wrapped around the rotating roller 42, and the length of the pull rope 46 is shortened; the other end of the pull rope 46 is connected to the hook ring 6 near the free end of the placement plate 3 through the hook 7, thereby applying an upward pulling force to the free end of the placement plate 3. The pulling force overcomes the weight of the placement plate 3 itself and the weight of any small, light items that may be stored on it, forcing the placement plate 3 to rotate upwards around its other end's first pivot 31, which is mounted in a first slot on the mounting plate 21. This causes it to rotate from a horizontally unfolded state toward the side wall of the extension 2 until it fits against the extension 2, achieving a compact, vertically folded state. During this process, the ratchet 44, coaxially fixed to the rotating roller 42, rotates accordingly. Under the continuous action of the torsion spring 47, the pawl 45, hinged to the mounting block 41212, ... The end is always pressed against the ratchet 44, and is sequentially engaged in its tooth groove as the ratchet 44 rotates; the ratchet 44 and the pawl 45 form a one-way clutch mechanism: it allows the rotating roller 42 to rotate freely in the direction of lifting the placement plate 3 to the storage state by the winding rope 46, but the mechanical interference of the pawl 45 engaging in the tooth groove strictly prohibits the rotating roller 42 from unwinding the rope 46 in the opposite direction; therefore, once the user stops turning the handle, the placement plate 3 is firmly locked in the vertical storage state by the rope 46 and the self-locking ratchet 44 mechanism. When the placement plate 3 needs to be used to place items, the user must first manually move or lift the tail of the pawl 45 to overcome the torque of the torsion spring 47, causing the tip of the pawl 45 to disengage from the tooth groove of the ratchet 44; this releases the mechanical limit on the reverse rotation of the rotating roller 42; at this time, the wound pull rope 46 is in a taut state, and under the action of the placement plate 3's own weight, the placement plate 3 tends to rotate downward around its axis of rotation, that is, from a vertical state to a horizontal state. This tendency is transmitted through the pull rope 46, driving the rotating roller 42 to rotate in the opposite direction, realizing the unwinding of the pull rope 46; the placement plate 3 swings smoothly downward under the action of gravity until it reaches a horizontal unfolded working state; in this state, the placement plate 3 can support items, and since the direction of gravity is perpendicular to the rotation axis, the placement plate 3 can naturally maintain stability, and the pull rope 46 is in a slack or slightly stressed state.
[0025] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
