Abstract
Description
Technical Field
[0001] This invention relates to the field of shelving technology, specifically to an absorbent shelving unit with enhanced stability. Background Technology
[0002] Existing wall-mounted shelving systems, especially those employing non-destructive installation techniques, offer significant advantages in convenience and wall protection. However, their fundamental safety risks have long remained unresolved. The core of this risk lies in the inherent limitation of the suction state being invisible and unknowable. Current products on the market that rely on negative pressure suction cups for fixation, regardless of whether they are supplemented with simple mechanical locking devices, lack any feedback mechanism that can intuitively and in real-time reflect the suction force within the cups. In actual use, due to factors such as temperature fluctuations, material creep, load changes, or microscopic deformation of the wall surface, the negative pressure within the suction cups slowly decays over time. This crucial failure process is completely hidden from the user. Users only passively discover the installation failure when the shelf shifts noticeably or detaches completely. This not only poses a risk of property damage but also potentially leads to personal injury accidents, severely limiting the reliability and user trust in such products.
[0003] The direct physical cause of suction cup failure typically stems from localized warping and stress concentration triggered by load torque. When the shelf is under load, the ends of the mounting plate are prone to slight warping under torque, causing the suction cup edges to lose their seal first, allowing air to leak in and gradually destroying the negative pressure chamber. Although existing technologies attempt to enhance adhesion by tightening screws in the central area, they fail to fundamentally solve the problem of uneven pressure distribution, thus failing to prevent this progressive failure starting from the edges. This failure mode is the concrete physical manifestation of the aforementioned hidden risk. In conclusion, there is room for technological improvement. Summary of the Invention
[0004] The present invention aims to solve the technical problem mentioned in the background art, namely the limitations of existing wall-mounted shelves, and to provide an adsorption shelf with enhanced stability.
[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an adsorption shelf with enhanced stability, comprising a shelf body; and further comprising:
[0006] Mounting mechanism; used to fix the shelf body to the support surface;
[0007] Support arms; two sets are symmetrically arranged, with their ends detachably connected to the mounting mechanism and the shelf body, respectively.
[0008] The installation mechanism includes a flexible bottom layer, a middle layer and a top layer arranged sequentially from the support surface outwards, and the back of the flexible bottom layer is provided with at least one suction cup;
[0009] The mounting mechanism also includes a locking component, which includes a threaded part that penetrates the surface layer and the intermediate layer and acts on the flexible bottom layer. By tightening the threaded part, the flexible bottom layer can be squeezed to deform locally toward the support surface.
[0010] The suction cup is equipped with an adsorption status indicator structure.
[0011] Furthermore, the number of threaded components is two, and their point of action is located near the edge of the flexible bottom layer.
[0012] Furthermore, the locking assembly also includes a disc-shaped extruder that mates with the threaded component. The extruder is disposed between the flexible bottom layer and the intermediate layer, and the end of the threaded component acts on the extruder.
[0013] Furthermore, a quick-release structure is provided between the shelf and the support arm; the quick-release structure includes a limiting slide bar provided at one end of the support arm near the shelf body, and a limiting slide groove provided on the shelf body to accommodate the limiting slide bar.
[0014] Furthermore, the end of the limiting slide rod is T-shaped, and the limiting slide groove is narrow at the top and wide at the bottom.
[0015] Furthermore, the suction cup includes a hard shell and a silicone disc, both of which are transparent, and the hard shell is threaded with locking bolts that extend out of the mounting mechanism.
[0016] Furthermore, the adsorption state indicator structure includes a hollow cylinder at the end of the locking bolt, the outer side of the hollow cylinder is fixed to the silicone disc, and its interior is connected to the negative pressure chamber of the suction cup; an indicator post is elastically provided inside the hollow cylinder, and the surface of the indicator post is coated with a fluorescent coating.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1:
[0031] Combined with appendix Figure 1-7 An enhanced stability adsorption shelf mainly consists of a shelf body 1, a mounting mechanism 2, and two sets of symmetrically arranged support arms 3.
[0032] The shelf body 1 can be made of metal, plastic or wood, and its specific shape can be a flat plate, grid or a tray with a rim, for carrying items;
[0033] Combined with appendix Figure 1 , 5 6. The mounting mechanism 2 is used to fix the entire shelf body 1 to a vertical support surface, such as a wall, glass, or tile. From the side closest to the support surface outwards, it includes a flexible bottom layer 21, a middle layer 22, and a top layer 23 in sequence. The flexible bottom layer 21 is preferably made of a material with good elasticity and sealing properties, such as silicone or rubber, and at least one suction cup 211 is fixedly installed on its back. In this embodiment, there is one suction cup 211, located approximately at the center of the mounting mechanism 2. The middle layer 22 can be made of a rigid or semi-rigid material, such as ABS plastic or metal plate, and is used to transmit and distribute pressure and support the locking bolts mentioned below. The top layer 23 constitutes the outer surface of the mounting mechanism 2.
[0034] Combined with appendix Figure 5 , 6 To prevent the edge of the mounting mechanism 2 from lifting due to torque after the shelf is loaded with items, which could lead to air leakage and failure of the suction cup 211, a locking assembly is provided. The locking assembly includes two threaded parts 24 that pass through the surface layer 23 and through the corresponding through holes on the intermediate layer 22, and finally have their ends act on the corresponding positions on the flexible bottom layer 21. The point of action is located on the flexible bottom layer 21 near its edge. When the threaded parts 24 are tightened, their ends squeeze the flexible bottom layer 21, causing it to produce controllable local elastic deformation, thereby pressing the edge of the mounting mechanism 2 more tightly onto the support surface, effectively counteracting the lifting tendency caused by the load, and ensuring that the edge seal of the suction cup 211 remains effective.
[0035] Combined with appendix Figure 1 , 2 Support arms 3, 4, are used to connect and support the shelf body 1. Both ends of the support arms are detachably connected to the surface layer 23 of the mounting mechanism 2 and the shelf body 1, respectively. To enable quick installation and removal of the shelf body 1, a quick-release structure is provided between the shelf body 1 and the support arms 3. Specifically, a limiting slide rod 31 is fixedly provided at one end of each support arm 3 near the shelf body 1. Correspondingly, a limiting groove 32 is provided on the back of the shelf body 1 at the position corresponding to the two support arms 3, capable of accommodating the corresponding limiting slide rod 31. Preferably, the end of the limiting slide rod 31 is T-shaped, and the cross-sectional shape of the limiting groove 32 is designed to be narrower at the top and wider at the bottom. During installation, simply align the T-shaped limiting slide rod 31 from below and push it upward into the corresponding limiting groove 32; a quick and stable connection can be achieved through shape interlocking, and it can withstand downward gravity. Disassembly is performed in the reverse direction.
[0036] Combined with appendix Figure 1 , 5 7. The suction cup 211 has an integrated suction status indicator structure to visually display its internal negative pressure status. Example 2:
[0037] Based on Example 1, this example refines the suction cup 211 and its adsorption state indicator structure;
[0038] Combined with appendix Figure 1 , 5 6, 7. The suction cup 211 specifically includes a rigid outer shell and a silicone disc attached thereto, both of which are transparent for easy observation of the indicator post 214 described below. A threaded boss is located at the center of the rigid shell, and a locking bolt 212 passes through the mounting mechanism 2 and is threadedly connected to the threaded boss on the rigid shell. By tightening the locking bolt 212, a pulling action is achieved, thereby pressing down the center of the silicone disc and creating an initial negative pressure inside, achieving initial adhesion and fixation to the wall.
[0039] The adsorption status indicator structure is integrated into the end of the locking bolt 212; a hollow cylinder 213 is fixedly connected to the end of the locking bolt 212, and the outer side of the end of the hollow cylinder 213 is fixedly connected to the central area of the silicone disc, for example by adhesive bonding or vulcanization; inside the hollow cylinder 213, an indicator post 214 that can slide along its axial direction is provided; the exposed end surface of the indicator post 214 is coated with a bright fluorescent coating, and a spring 215 is provided at the inner bottom of the hollow cylinder 213, one end of the spring 215 abutting against the bottom of the hollow cylinder 213, and the other end abutting against the inner end of the indicator post 214, thereby providing the indicator post 214 with an elastic force that always tends to push it outward;
[0040] The working principle is as follows: When the suction cup 211 is in good adsorption state and the internal negative pressure is strong enough, the external atmospheric pressure acts on the exposed end face of the indicator column 214 through the air passage, which will overcome the elastic force of the spring 215 and completely press the indicator column 214 into the hollow cylinder 213. At this time, the fluorescent coating on the indicator column 214 cannot be seen from the outside of the mounting mechanism 2, indicating that the state is safe.
[0041] When the suction cup 211 slowly leaks air at its edge and the internal negative pressure weakens due to various reasons, such as temperature changes, slight vibrations, or long-term load, the atmospheric pressure acting on the indicator post 214 also decreases. When this pressure is insufficient to completely balance the elastic force of the spring 215, the indicator post 214 will move a small distance outward from the hollow cylinder 213 under the action of the spring force. Once it moves, the part coated with fluorescent coating will be exposed from the observation window, forming a conspicuous visual warning signal. After seeing this signal, the user can restore the suction force in time by tightening the locking bolt 212 or checking the installation status, thereby performing preventive maintenance before the shelf becomes loose or falls off, greatly improving the safety and reliability of use. Example 3:
[0042] As a further optimization of the locking assembly, a disc-shaped extruder can be added between the flexible bottom layer 21 and the intermediate layer 22, below the point of action of the threaded part 24. The end of the threaded part 24 acts on the upper surface of the extruder. In this way, when the threaded part 24 is tightened, the pressure is evenly transmitted to a small circular area of the flexible bottom layer 21 through the disc-shaped extruder, avoiding local excessive pressure or damage to the flexible material that may be caused by the end of the threaded part, making the extrusion deformation smoother and more controllable.
[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
