Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a folding shelving. Background Technology

[0002] As life goes on, many families accumulate more and more household items, so they need storage shelves to organize and arrange these items. If storage shelves were not installed in the early planning stages, new storage shelves will need to be installed by the family.

[0003] Currently, most shelving units are designed for easy transportation, but these designs require manual assembly by the user. When there are many parts, the user's hands-on skills are required to be high. In addition, due to the problem of assembly precision, the shelving unit may be twisted after assembly, making it unusable.

[0004] Therefore, folding shelves have emerged, which use a hinged structure to fold into a flat state for easy transportation. However, these structures lack locking devices, or the locking devices still require manual screwing by the user. When unfolding or storing, manual disassembly and assembly with tools are still required, which does not provide a good user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a folding storage rack, which solves the problem that existing storage racks still require manual disassembly and assembly with tools when unfolded or when they need to be folded up, thus failing to provide users with a good operating experience.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a folding storage rack, including a first support and a second support arranged in parallel, and storage panels on both sides respectively hinged to the first support and the second support, the first support being provided with hanging ears for fixing to the wall, and further including:

[0007] The self-unlocking mechanism includes an unlocking component and a locking component. The unlocking component is located on the top of the second bracket and includes a driving component, a telescopic component, and a connecting component. The driving component is located on the top of the second bracket, the telescopic component is located between the second bracket and the driving component, and the two ends of the connecting component are respectively connected to the driving component and the locking component. The connecting component is distributed along the second bracket. The locking component is located on the first bracket. When the second bracket is parallel to the first bracket, the locking component engages with the side wall of at least one shelf. After the driving component is activated, it drives the locking component away from the shelf through the connecting component.

[0008] In one embodiment, the locking assembly includes a fixed base, a limiting rod, and an adjusting spring. The fixed base is fixed to the side of the shelf corresponding to the side wall of the shelf, near the second bracket of the first bracket. The fixed base is provided with a sliding through hole. The end of the limiting rod away from the shelf is connected to the connector. The shelf is provided with a limiting hole corresponding to the limiting rod. The limiting rod slides along the sliding through hole and extends into the limiting hole under the action of the adjusting spring.

[0009] In one embodiment, the bottom of the fixing base is provided with support columns distributed in a horizontal direction, which keep the shelf horizontal after the support columns abut against the shelf.

[0010] In one embodiment, the second bracket has a connecting channel inside, and the connector is disposed in the connecting channel.

[0011] In one embodiment, a transition cylinder is provided between the second bracket and the driving member. One end of the transition cylinder is connected to the second bracket, and the other end of the transition cylinder is sleeved on the driving member. The transition cylinder has a driving cavity inside, and the driving cavity is connected to the connecting channel.

[0012] In one embodiment, the connector includes a nylon rope, a first pulley, and a second pulley. One end of the nylon rope is connected to a transition cylinder. The first pulley is disposed in the drive cavity and at the same height as the connection end of the nylon rope and the transition cylinder. The second pulley is disposed above the first pulley. The nylon rope enters the connection channel after passing through the first pulley and the second pulley. The drive end of the drive member is connected to the nylon rope between the first pulley and the transition cylinder.

[0013] In one embodiment, the driving end of the driving member is provided with a pressing ball head.

[0014] In one embodiment, the end of the connecting channel is provided with a connecting outlet, and a third pulley is provided at the connecting outlet to guide the nylon rope to the connecting outlet.

[0015] In one embodiment, the connector further includes a fourth pulley, which is located on the same straight line as the limiting rod and is disposed on the first bracket. The fourth pulley guides the nylon rope to the end of the limiting rod away from the shelf.

[0016] In one embodiment, the end of the fourth pulley away from the limiting rod is provided with an arc-shaped wall, which forms a guide channel with the fourth pulley. The nylon rope passes through the guide channel and is connected to the limiting rod.

[0017] The beneficial effects of this utility model are as follows:

[0018] Conventional storage racks are shipped in disassembled units, requiring users to assemble them themselves upon receipt. While this saves shipping space, it is difficult to assemble and requires users to have a high level of dexterity. The folding storage rack provided by this invention, however, employs a folding design, allowing the shelf to rotate relative to the first support, thereby adjusting the position of the second support relative to the first support to achieve a folded state.

[0019] In practical applications, existing shelves typically use screws, buckles, or other methods for locking, thereby enabling the switching between folded and unfolded states and ensuring stability in the unfolded state. However, these solutions still require users to disassemble or install the shelves at the locking position during actual switching. Furthermore, after the shelves are mounted on the wall, manual unlocking or locking operations are obstructed by the shelf frame, which significantly impacts the user experience.

[0020] Therefore, this utility model is equipped with a self-unlocking mechanism. The locking component automatically locks upon unfolding, ensuring rapid locking and limiting the rotation angle of the shelf, thus guaranteeing the stability of the shelf. Simultaneously, an unlocking component is located at the top of the second bracket. By pressing the drive component, the user can actuate the connecting component, moving the locking component away from the shelf and unlocking the shelf. The unlocking operation is simple and convenient, perfectly complementing the lifting of the second bracket during the folding process, resulting in a smooth overall folding operation and a superior user experience.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please refer to Figures 1 to 10 A folding shelf includes a first support 1 and a second support 2 arranged in parallel, and a shelf 3 hinged to the first support 1 and the second support 2 on both sides respectively. The first support 1 is provided with a hanging lug 11 for fixing to the wall, and also includes:

[0037] The self-unlocking mechanism includes an unlocking component 4 and a locking component 5. The unlocking component 4 is located on the top of the second bracket 2 and includes a driving member 41, a telescopic member 42, and a connecting member 43. The driving member 41 is located on the top of the second bracket 2, the telescopic member 42 is located between the second bracket 2 and the driving member 41, and the two ends of the connecting member 43 are respectively connected to the driving member 41 and the locking component 5. The connecting member 43 is distributed along the second bracket 2. The locking component 5 is located on the first bracket 1. When the second bracket 2 is parallel to the first bracket 1, the locking component 5 engages with the side wall of at least one shelf 3. After the driving member 41 is activated, it drives the locking component 5 away from the shelf 3 through the connecting member 43. Specifically, the locking component 5 can adopt a structure such as an elastic pin or a telescopic buckle, so that the shelf 3 can be automatically locked, and can be unlocked when the connecting member 43 is activated. No specific limitation is made.

[0038] Conventional shelving locking mechanisms typically require manual installation or disassembly. Therefore, to ensure automatic engagement between the locking component 5 and the shelf 3, the locking component 5 employs an elastic support design. Specifically, the locking component 5 includes a fixed base 51, a limiting rod 52, and an adjusting spring 53. The fixed base 51 is fixed to the side of the first bracket 1 near the second bracket 2, corresponding to the side wall of the shelf 3. The fixed base 51 has a sliding through hole 511. The end of the limiting rod 52 away from the shelf 3 is connected to the connecting piece 43. The shelf 3 has a limiting hole 31 corresponding to the limiting rod 52. Under the action of the adjusting spring 53, the limiting rod 52 slides along the sliding through hole 511 and extends into the limiting hole 31. This design allows the adjusting spring 53 to push the limiting rod 52 partially into the limiting hole 31, thus connecting the fixed base 51 and the shelf 3, restricting the rotation of the shelf 3, and ensuring a stable lock. Simultaneously, it facilitates the connecting piece 43 in pulling the limiting rod 52, ensuring smooth unlocking.

[0039] Preferably, the side wall of the shelf 3 is provided with an arc-shaped chamfer 32, which corresponds to the end of the limiting rod 52 away from the fixed seat 51. During the descent of the shelf 3, after the end of the limiting rod 52 away from the fixed seat 51 contacts the arc-shaped chamfer 32, the limiting rod 52 slides under the action of the arc-shaped chamfer 32 and gradually compresses the adjusting spring 53. After the limiting hole 31 is aligned with the limiting rod 52, the limiting rod 52 slides into the limiting hole 31 under the action of the adjusting spring 53, thus completing the locking.

[0040] After setting the limiting rod 52, the locking component 5 can limit the rotation angle of the shelf 3. However, relying solely on the limiting rod 52 to lock the shelf 3, the shelf 3 will continue to rotate downwards after an object is placed on it. This causes the overall weight to be transmitted to the limiting rod 52, resulting in a large tangential force on the limiting rod 52. Over long-term use, this may cause the limiting rod 52 to deform or break, affecting the service life of the folding shelf. Therefore, horizontally distributed support columns 54 are set at the bottom of the fixing base 51. After the support columns 54 abut against the shelf 3, they keep the shelf 3 in a horizontal state. That is, the support columns 54 are set at the bottom of the shelf 3 to restrict it. The shelf 3 and the limiting rod 52 work together to limit and lock the shelf 3. The limiting columns prevent the shelf 3 from flipping upwards, and the support columns 54 prevent the shelf 3 from rotating downwards, further ensuring the stability of the unfolded state. At the same time, this arrangement allows the weight of the shelf 3 and the objects placed on it to be transmitted to the first bracket 1 along the support column 54, avoiding continuous stress on the limiting rod 52, preventing deformation of the limiting rod 52 that would reduce locking accuracy, and ensuring the normal operation of automatic locking.

[0041] In actual use, the shelf may hold various items. When taking or placing items, the connector 43 may be touched, causing the locking component 5 to unlock, resulting in accidental operation. Therefore, a connecting channel 21 is provided inside the second bracket 2, and the connector 43 is placed inside the connecting channel 21 to prevent the connector 43 from being interfered with by external objects, ensuring the normal operation of the locking component 5 and the unlocking component 4. Preferably, the side wall of the shelf 3 is provided with a protective shell, and the connector 43 passes through the protective shell to connect with the locking component 5. This further avoids the connector 43 being exposed, ensuring the normal operation of the locking component 5 and the unlocking component 4.

[0042] Preferably, the tops of the first bracket 1 and the second bracket 2 adopt an arc-shaped structure, which ensures convenient gripping and lifting while effectively preventing the nylon rope 431 from being scratched by the edge, thus improving the overall service life. More preferably, there are two sets of connectors 43 and locking components 5, located at both ends of the shelf 3, respectively. A single drive unit 41 operates both sets of connectors 43 simultaneously, improving stability and convenience.

[0043] Normally, the frame structure of the second bracket 2 is relatively thin. If the driving component 41 and the connecting component 43 are directly mounted on the second bracket 2, the extension distance of the driving component 41 may be too small, requiring greater force to press, resulting in a poor user experience. Therefore, a transition cylinder 22 is provided between the second bracket 2 and the driving component 41. One end of the transition cylinder 22 is connected to the second bracket 2, and the other end is fitted onto the driving component 41. The transition cylinder 22 has a driving cavity 23 inside, which communicates with the connecting channel 21. The transition cylinder 22 provides a larger installation space and a greater extension range of the driving component 41, reducing the force required to press and effectively improving the user experience.

[0044] In this embodiment, the connector 43 includes a nylon rope 431, a first pulley 432, and a second pulley 433. One end of the nylon rope 431 is connected to the transition cylinder 22. The first pulley 432 is located inside the drive cavity 23 and is at the same height as the connection end of the nylon rope 431 and the transition cylinder 22. The second pulley 433 is located above the first pulley 432. The nylon rope 431 enters the connection channel 21 after passing through the first pulley 432 and the second pulley 433. The drive end of the drive member 41 is connected to the nylon rope 431 between the first pulley 432 and the transition cylinder 22. The first pulley 432 and the second pulley 433 form a pulley group, changing the direction of the nylon rope 431. Then, the nylon rope 431 is pulled by the extension and retraction process of the drive member 41, thereby pulling the limiting rod 52.

[0045] In this embodiment, the driving end of the driving member 41 is provided with a pressing ball head 411. The pressing ball head 411 makes the pressing of the driving member 41 on the nylon rope 431 more gentle, avoids scratching the nylon rope 431, and improves the overall service life.

[0046] In this embodiment, the end of the connecting channel 21 is provided with a connecting outlet 211, and a third pulley 434 is provided at the connecting outlet 211. The third pulley 434 guides the nylon rope 431 to the connecting outlet 211.

[0047] In this embodiment, the connector 43 further includes a fourth pulley 435. The fourth pulley 435 is located on the same straight line as the limiting rod 52 and is mounted on the first bracket 1. The fourth pulley 435 guides the nylon rope 431 to the end of the limiting rod 52 away from the shelf 3. Specifically, the fourth pulley 435 is horizontally positioned to guide the nylon rope 431 and prevent it from being scratched by the side wall of the fixing seat 51.

[0048] Because the fourth pulley 435 is horizontally positioned, when the folding shelf is switched to the folded state, the direction of the nylon rope 431 is nearly perpendicular to the direction of the fourth pulley 435. This makes it very easy for the nylon rope 431 to come loose from the fourth pulley 435. Consequently, during further switching, the nylon rope 431 may become entangled in the fourth pulley 435 or be scratched, affecting the switching process. Therefore, an arc-shaped wall 436 is provided at the end of the fourth pulley 435 furthest from the limiting rod 52. The arc-shaped wall 436 and the fourth pulley 435 form a guide channel, through which the nylon rope 431 passes and connects to the limiting rod 52. The arc-shaped wall 436 restricts the movement of the nylon rope 431, preventing it from coming loose from the fourth pulley 435 in the folded state. This ensures that the switching between different states of the folding shelf can proceed normally, effectively improving the user experience.

These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
