Abstract
Description
Technical Field
[0001] This invention relates to the field of furniture, and more particularly to a folding storage rack. Background Technology
[0002] With the increasing popularity of small apartments, rentals, and flexible office spaces, users have placed higher demands on the space utilization efficiency and functional versatility of furniture.
[0003] Currently, storage furniture on the market has significant functional shortcomings. Traditional shelves and tables are single-function; if users need both storage and desktop functionality, they must purchase two separate pieces, which not only occupies limited living or office space but also increases expenses. Even if some products attempt to convert shelves into desktops, their frame structures are often not stable enough when used as desktops, with limited load-bearing capacity, making them prone to wobbling and affecting safety and practicality.
[0004] In terms of storage flexibility, most existing shelving units have fixed shelves. When users need to store tall items such as boots, computer cases, or kitchen appliances, the fixed shelf height makes it impossible to effectively utilize vertical space. Either the items cannot be placed, or there is a great waste of upper space, reducing the actual storage flexibility and space adaptability.
[0005] In addition, foldable storage racks have emerged on the market to save space when not in use. However, these products have shortcomings in terms of ease of folding and stability. On the one hand, some products are still quite large when folded, making it difficult to fit them into narrow spaces such as under beds or in closet gaps. On the other hand, many folding racks lack an effective locking mechanism when fully folded, causing the folding frame (such as X-shaped supports) to easily loosen or come apart accidentally when users move them or lean them against a wall, which is not only inconvenient to operate but also poses a safety hazard. Summary of the Invention
[0006] The purpose of this invention is to provide a folding storage rack that solves the problems of large space occupation and high purchase cost caused by the single function of existing storage products; at the same time, it solves the contradiction between traditional storage racks that cannot take into account multi-layer large-capacity storage and compact folding and portability, as well as the problem that they cannot adapt to small storage spaces; in addition, it also solves the problems of existing convertible furniture that is cumbersome to operate and requires tools, as well as poor structural stability and easy shaking after the form is changed.
[0007] To achieve the above objectives, the present invention provides the following technical solution: A folding storage rack includes: a base, on both sides of which a support component one and a support component two are rotatably connected; multiple support frames are rotatably connected between the support component one and the support component two to form an X-shaped cross-folding structure; a storage board is fixedly connected to the top between two opposite support frames; two fixing components are provided on the outer side of each support frame for detachable fixing to accommodate items of different heights; and two locking components are provided on both sides of the base to prevent the folding storage rack from shaking during use. The fixing component includes a limiting rod, a connecting rod fixedly connected to the outside of the limiting rod, and a spring fixedly connected to the outside of the connecting rod. Both the first support component and the second support component include an outer rod. The outer rod has multiple limiting grooves on its outside. An adjustment component is provided on the top of the outer rod to adjust the height of the first support component and the second support component.

A multiple limiting groove 4 is provided on one side of the movable rod, and a multiple limiting groove 2 is provided on the other side of the movable rod.
[0009] Preferably, the locking assembly includes a fixed base, a pull rod is provided on the outside of the fixed base, a rotating rod is fixedly connected to the outside of the pull rod, a connecting plate is rotatably connected to the outside of the rotating rod, and a spring is fixedly connected to the outside of the connecting plate.
[0010] Preferably, the folding shelf has an unfolded state and a folded state; when in the unfolded state, the two locking components on the same side of the base lock the first support component and the second support component respectively; when in the folded state, the two locking components on the same side of the base lock the second support component simultaneously.
[0011] Preferably, the diameters of the limiting groove one, the limiting groove three, and the limiting groove four are the same.
[0012] Preferably, the top of the base is fixedly connected to two fixing rods.
[0013] Preferably, the limiting rod is slidably connected to the outside of the support frame, a portion of the limiting rod is slidably connected to the inside of the limiting groove, the connecting rod is slidably connected to the inside of the support frame, and the spring is fixedly connected to the inside of the support frame.
[0014] Preferably, another portion of the limiting rod 1 is slidably connected inside the limiting groove 4; when the height of the support component 1 and the support component 2 is adjusted using the adjusting component, a portion of the limiting rod 1 is slidably connected inside the limiting groove 3.
[0015] Preferably, the inner rod is fixedly connected to the top of the outer rod, the second limiting rod is slidably connected inside the second limiting groove, the second connecting rod is slidably connected inside the inner rod, and the second spring is fixedly connected inside the inner rod.
[0016] Preferably, the fixing seat is fixedly connected to the outside of the base, the spring is fixedly connected to the inside of the base, and the connecting plate is slidably connected to the inside of the base.
[0017] In summary, the present invention has at least one of the following beneficial technical effects: 1.

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 The present invention will be further described in detail below.
[0022] Reference Appendix Figure 1 - Appendix Figure 9 This invention provides a folding storage rack, including a base 1. Support components one and two are rotatably connected to both sides of the base 1. Multiple support frames 3 are rotatably connected between support components one and two, forming an X-shaped cross-folding structure. A storage board 2 is fixedly connected to the top between two opposing support frames 3. Two fixing components are provided on the outer side of each support frame 3 for detachable fixing, adapting to the storage of items of different heights. Two locking components are provided on both sides of the base 1 to prevent the folding storage rack from shaking during use. The fixing components include a limiting rod 4, a connecting rod 5 fixedly connected to the outer side of the limiting rod 4, and a spring 6 fixedly connected to the outer side of the connecting rod 5. Both support components one and two include an outer rod 7, with multiple limiting grooves 8 on the outer side of the outer rod 7. An adjustment component is provided at the top of the outer rod 7 for adjusting the height of support components one and two.
[0023] The diameters of limiting groove 1 (8), limiting groove 3 (18), and limiting groove 4 (22) are the same. Two fixing rods 21 are fixedly connected to the top of the base 1. Limiting rod 1 (4) is slidably connected to the outside of the support frame 3, with a portion of limiting rod 1 (4) slidably connected to the inside of limiting groove 1 (8). Connecting rod 1 (5) is slidably connected to the inside of the support frame 3, and spring 1 (6) is fixedly connected to the inside of the support frame 3.
[0024] Specifically, base 1 is the basic support component of the entire folding shelf, ensuring the overall stability of the device when unfolded. In the folded state, it provides a neat bottom structure for easy storage and transport. Support components one and two form an X-shaped cross-folding structure through a rotatable connection with support frame 3, providing stable support for shelf 2 and ensuring the stability of the storage space in the unfolded state. They also participate in the folding action of the device, assisting in achieving compact storage. Shelf 2 directly supports the storage of items; its multi-layer design allows for the categorized storage of multiple items. The upper shelf 2 can be used as a desktop after the frame height is adjusted, achieving both storage and desktop functionality. The fixing component is used to detachably fix support frame 3, and its own structure allows for flexible height adjustment of shelf 2, adapting to the storage needs of items of different heights, improving the storage flexibility of the shelf. It can be operated without additional tools, simplifying the height adjustment process.
[0025] The locking mechanism prevents the folding shelf from shaking during use. In the unfolded state, it locks support components one and two respectively, ensuring the overall structural stability of the device. In the folded state, it locks support component two simultaneously to prevent the device from accidentally disassembling during handling or storage, improving safety and convenience. The limiting rod 4 is the core actuator of the fixing mechanism. By sliding into different limiting slots (limiting slot 1 8, limiting slot 3 18, limiting slot 4 22), it enables the detachable fixing and height adjustment of the shelf 2, adapting to the storage needs of items of different heights. The connecting rod 5 transmits the elastic force of the spring 6, ensuring that the limiting rod 4 can stably engage or disengage from the limiting slots. The spring 6 provides elastic restoring force to the limiting rod 4; after pressing the limiting rod 4 to adjust the position of the shelf 2, the spring... The first 6 can automatically push the limiting rod 4 into the corresponding limiting slot, simplifying the operation process; the outer rod 7 serves as the basic structure of support component one and support component two, providing an installation carrier for the adjustment component. The limiting slot 8 on the outer rod 7 cooperates with the limiting rod 4 to achieve initial fixation and height adjustment of the shelf 2; the limiting slot 8 and the limiting rod 4 cooperate to form a locking point. Through multiple evenly distributed designs, the shelf 2 is provided with multiple height adjustment options to meet the storage adaptation needs of items of different heights; the adjustment component is used to adjust the overall height of support component one and support component two, changing the overall shape of the device so that the upper shelf 2 can be converted into a desktop, realizing the dual function of storage and desktop, meeting diverse usage scenarios, and can be stably locked after adjustment to ensure safety.
[0026] The limiting grooves 1-8, 3-18, and 4-22 have the same diameter, ensuring that the limiting rod 4 can smoothly switch between sliding and engaging in the three different limiting grooves without needing to adapt to different sized limiting grooves. This simplifies the design and manufacturing of the limiting rod 4 and ensures that it can stably engage in any corresponding limiting groove when adjusting the height of the shelf 2 or fixing the shelf 2. This avoids problems such as loose engagement or inability to engage due to mismatched diameters, and improves the reliability of the cooperation between the fixing component and the adjusting component. The fixing rod 21 enhances the structural strength of the base 1, improves the overall stability of the device, and prevents the base 1 from deforming or shaking when unfolded for use. It has a foldable structure.
[0027] The limiting rod 4 is used to cooperate with the limiting groove 8 to provide a stable support and fixing point for the shelf 2; the connecting rod 5 is slidably connected inside the support frame 3 to ensure that the trajectory of the limiting rod 4 is stable when it moves, and to avoid deviation; the spring 6 provides a stable elastic restoring force for the limiting rod 4, and the connection of the three to the support frame 3 makes the fixing components integrated on the support frame 3, without occupying additional space, and ensuring the compactness of the device structure.
[0028] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 The adjustment assembly includes an inner rod 9, with multiple limiting grooves 18 on the outer side of the inner rod 9. A limiting rod 12 is slidably connected inside the inner rod 9. A connecting rod 13 is fixedly connected to the outer side of the limiting rod 12. A spring 14 is fixedly connected to the bottom of the connecting rod 13. A movable rod 10 is slidably connected to the outer side of the inner rod 9. Multiple limiting grooves 22 are opened on one side of the movable rod 10, and multiple limiting grooves 11 are opened on the other side of the movable rod 10.
[0029] Another part of the limiting rod 4 is slidably connected inside the limiting groove 22; when the height of the support component 1 and the support component 2 is adjusted using the adjusting component, part of the limiting rod 4 is slidably connected inside the limiting groove 18.
[0030] The inner rod 9 is fixedly connected to the top of the outer rod 7, the second limiting rod 12 is slidably connected to the inside of the second limiting groove 11, the second connecting rod 13 is slidably connected to the inside of the inner rod 9, and the second spring 14 is fixedly connected to the inside of the inner rod 9.
[0031] Specifically, the inner rod 9 provides sliding and installation space for the movable rod 10 and the second limiting rod 12, serving as the core support structure for the adjustment assembly; the third limiting groove 18 cooperates with the first limiting rod 4 to provide a locking point for the shelf 2 after the overall frame height is adjusted, ensuring the stability of the shelf 2 after adjustment; the second limiting rod 12, as the locking actuator of the adjustment assembly, achieves height fixation of the movable rod 10 by engaging the second limiting groove 11; the second connecting rod 13 transmits the elastic force of the second spring 14; the second spring 14 lifts the second limiting rod 12. Provides elastic restoring force; after pressing the limit rod 12 to adjust the height of the movable rod 10, the spring 14 can automatically push the limit rod 12 into the corresponding limit groove 11, simplifying the overall height adjustment operation; the movable rod 10 can slide along the inner rod 9 to adjust its height; the limit groove 22 cooperates with the limit rod 4 to provide a locking point for the shelf 2 after the height of the movable rod 10 is adjusted; the limit groove 11 cooperates with the limit rod 12 to form a locking point, and the design of multiple limit grooves 11 provides multiple height adjustment options for the movable rod 10.
[0032] Limiting rod 4 strengthens the connection and fixation between the shelf 2 and the movable rod 10, ensuring that the shelf 2 can be synchronously and stably fixed after the height of the movable rod 10 is adjusted; when adjusting the height of the support component, limiting rod 4 enables the shelf 2 to adjust its position synchronously with the change in the height of the support component, meeting the fixing requirements of the shelf 2 under different height configurations of the device and improving the flexibility of use.
[0033] The inner rod 9 provides a stable sliding support base for the movable rod 10, ensuring that the movable rod 10 moves smoothly along the trajectory of the inner rod 9 when adjusting its height; the second limiting rod 12 and the second limiting groove 11 realize the height locking of the movable rod 10 and the inner rod 9; the second connecting rod 13 provides a stable guide for the movement of the second limiting rod 12; the second spring 14 provides a reliable elastic restoring force for the second limiting rod 12.
[0034] Reference Appendix Figure 1 Appendix Figure 8 and attached Figure 9 The locking assembly includes a fixed base 15, a pull rod 16 is provided on the outside of the fixed base 15, a rotating rod 20 is fixedly connected to the outside of the pull rod 16, a connecting plate 19 is rotatably connected to the outside of the rotating rod 20, and a spring 17 is fixedly connected to the outside of the connecting plate 19.
[0035] The fixed base 15 is fixedly connected to the base 1, the spring 17 is fixedly connected inside the base 1, and the connecting plate 19 is slidably connected inside the base 1.
[0036] Specifically, the fixed base 15 provides a rotation support point for the pull rod 16 and the rotating rod 20, serving as the basic mounting structure for the locking assembly. The pull rod 16 is the operating component of the locking assembly, controlling the unlocking and locking of the locking structure by pulling and rotating it. In the unfolded state, it locks support assembly one and support assembly two respectively, and in the folded state, it locks support assembly two simultaneously. The rotating rod 20 converts the linear pulling of the pull rod 16 into the opening and closing action of the locking structure. The connecting plate 19 transmits the elastic force of the spring three 17, enabling the operation of the pull rod 16 to synchronously drive the rotating rod 20. The spring three 17 provides an elastic restoring force for the connecting plate 19 and the rotating rod 20. After releasing the pull rod 16, the spring three 17 can push the connecting plate 19 to drive the rotating rod 20 to reset, causing the locking assembly to automatically engage with the corresponding support assembly, ensuring stable locking in the unfolded or folded state and preventing accidental loosening.
[0037] The fixed base 15 is fixedly connected to the outside of the base 1, the spring 17 is fixedly connected to the inside of the base 1, and the connecting plate 19 is slidably connected to the inside of the base 1.
[0038] The fixed base 15 is stabilized by the base 1, providing a stable mounting support point for the pull rod 16 and the rotating rod 20; the spring 17 can provide a continuous and stable elastic restoring force for the connecting plate 19; the connecting plate 19 ensures that the rotating rod 20 moves with a precise trajectory, avoiding the locking component from failing to lock accurately due to the shaking of the connecting plate 19. The connection of the three components with the base 1 makes the locking component stably integrated on the base 1, improving the overall working reliability of the locking component.
[0039] Reference Appendix Figure 1 and attached Figure 2 The folding shelf has an unfolded state and a folded state; when it is in the unfolded state, the two locking components on the same side of the base 1 lock the support component one and the support component two respectively; when it is in the folded state, the two locking components on the same side of the base 1 lock the support component two.
[0040] Specifically, the locking components can switch the locking object according to different states of the device. In the unfolded state, the two locking components on the same side lock the support component one and the support component two respectively, providing independent and stable locking force for both. In the folded state, the two locking components lock the support component two at the same time, firmly fixing the device in a compact folded form, preventing the support components from accidentally loosening and falling apart during transportation or storage, which not only ensures safety of use but also improves the convenience of storage.
[0041] Working Principle: When the folding shelf needs to be used, its folding lock must first be released. By manipulating the pull rod 16 outward, the pull rod 16 drives the rotating rod 20 and the connecting plate 19 to move synchronously, compressing the spring 17 and causing the locking structure to disengage from the support component 2. At this time, the pull rod 16 can be rotated to temporarily hold it in the unlocked position. After unlocking, pull open the support component 1 and support component 2. The X-shaped cross-folding structure formed by the connection of multiple support frames 3 between them unfolds, causing the shelf 2 to return to its position layer by layer, forming a multi-layered storage space. When the shelf is fully unfolded, rotate and release the pull rod 16 again. Under the rebound force of the spring 17, the end of the locking component will respectively engage with the corresponding positions of support component 1 and support component 2, achieving a firm lock on the two components, thereby ensuring the structural stability of the shelf in the unfolded state and preventing shaking.
[0042] This folding storage rack features flexible height adjustment to suit different usage scenarios.
[0043] When the height of a single shelf 2 needs to be adjusted, press the limiting rod 4 inward. The limiting rod 4 drives the connecting rod 5 to compress the spring 6, causing it to disengage from the limiting groove 8 or the limiting groove 22. At this time, the shelf 2 can slide freely along the support frame 3 to the target position. After releasing, the spring 6 automatically rebounds, pushing the limiting rod 4 into the new limiting groove, thus completing the fixation of the shelf 2.
[0044] When the overall frame height needs to be adjusted to use the upper layer as a desktop, press the limiting rod 12 in the adjustment assembly inward. The limiting rod 12 drives the connecting rod 13 to compress the spring 14, causing it to disengage from the limiting groove 11, thereby unlocking the movable rod 10. At this time, the height of the movable rod 10 can be freely adjusted. After reaching the desired height, align the limiting rod 12 with the other limiting groove 11. The spring 14 will automatically push the limiting rod 12 into the groove, locking the movable rod 10 and completing the overall height adjustment. After adjustment, the upper shelf 2 can be used as a flat desktop, while the lower shelf 2 continues to retain its storage function.
[0045] When the shelf needs to be folded for storage or transformed into a compact desktop mode, the locking mechanism must first be released. Then, push support components one and two inwards in the opposite direction, and the X-shaped folding structure will begin to close. During this process, the multiple shelves 2 will fit tightly together, ultimately forming a compact unit, which can then be used as a low desktop. After the transformation is complete, return it to its original position and release the pull rod 16. Both locking components will then lock onto support component two, securing the folded state. When no longer needed, this folded state represents the final storage configuration. Its compact size allows users to store it in small spaces such as under the bed or in closet gaps, achieving efficient space utilization.
