[0002] As modern life demands ever-increasing space utilization, hanging storage devices, as one of the solutions to improve space efficiency, have been widely used in homes, offices, and other environments.

[0003] In existing technologies, no-drill suction cups and nail-free adhesives are gradually becoming the mainstream fixing methods. Suction cup fixing is convenient, allowing for immediate use without damaging the wall. However, traditional suction cups are prone to detachment over prolonged use due to vacuum leakage or aging, and cannot be reused, thus reducing the product's lifespan. On the other hand, nail-free adhesives require additional auxiliary materials during installation and take hours or even longer to fully cure, affecting their immediacy. Furthermore, once fixed, nail-free adhesives are difficult to adjust, limiting user flexibility during installation. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0022] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, front, back, left, and right sides are shown.

[0023] like Figures 1 to 3 As shown, this application provides an adsorption-type hanging device. The device includes: an adsorption assembly 11, a housing 12, a piston 13, a pressing component 14, and a one-way valve 15.

[0024] Specifically, the right end face of the adsorption component 11 is provided with an exhaust groove 111, and a suction cup adsorption part 112 is provided around the exhaust groove 111. The adsorption component 11 is provided with a first exhaust pipe 113 extending in the left-right direction in the middle. The right end of the exhaust pipe is provided with a first platform 1131, and a strong adhesive adsorption part 114 is provided on the right end face of the first platform 1131.

[0025] Piston 13 is movably disposed in first exhaust pipe 113. When piston 13 moves relative to exhaust groove 111, it compresses the air in exhaust groove 111, causing the air to be expelled from exhaust groove 111 under pressure. A second exhaust pipe 131 extending in a left-right direction is provided in the middle of piston 13. An exhaust port 1311 is provided on the right side of the second exhaust pipe 131. A negative pressure space 100 communicating with exhaust groove 111 is formed between piston 13 and first exhaust pipe 113. A first spring 132 is provided within negative pressure space 100. The first spring 132 can maintain the negative pressure state of negative pressure space 100.

[0026] A one-way valve 15 is at least partially disposed in the second exhaust pipe 131, which restricts air from flowing into the first exhaust pipe 113 from the exhaust port 1311. A pressing member 14 is at least partially disposed on the right side of the piston member 13, and abuts against the piston member 13 to drive the piston member 13. When the pressing member 14 drives the piston member 13 to move to the right, the piston member 13 compresses the air in the negative pressure space 100. The air pressure is greater than the resistance of the one-way valve 15, allowing the air to be discharged from the negative pressure space 100 through the one-way valve 15. The outer shell 12 is at least partially fitted onto the adsorption assembly 11 and the pressing member 14, and its outer peripheral wall is provided with an anti-detachment member 121 to prevent the object to be hung from detaching.

[0027] The fixing device achieves rapid adsorption and stable fixation of the hanging item by setting an exhaust groove 111 and a suction cup adsorption part 112 in the adsorption assembly 11, and by driving the piston part 13 through the pressing part 14 to expel air and form a negative pressure space 100. Simultaneously, the fixing device combines the advantages of both suction cups and nail-free strong adhesive; users can choose to use the suction cup for immediate fixation as needed, or after a period of use, increase the attraction force by pressing to solidify the suction cup's fixation by creating a vacuum. Once the final position is determined, users can also choose to use nail-free strong adhesive for permanent fixation to extend the product's lifespan. Furthermore, the device eliminates the need for complex rotation or locking operations; simple pressing is all that's required for adsorption, greatly reducing the difficulty of use and improving efficiency.

[0028] like Figure 1 As shown, the first platform 1131 has a mounting hole 115 in the middle, so that when the suction cup and the nail-free strong adhesive fail, the fixing device can be fixed by screws, which improves the stability of the fixing device installation.

[0029] like Figure 2As shown, the piston component 13 includes a piston ring 133 and a connecting ring 134. The piston ring 133 and the connecting ring 134 are fixedly connected or integrally formed so that the one-way valve 15 is sealed in the piston component 13 to achieve one-way exhaust. The connecting ring 134 abuts against the pressing member 14. The piston component 13 is provided with a sealing ring 135 that can cooperate with the inner wall of the first exhaust pipe 113. The sealing ring 135 can reduce gas leakage in the negative pressure space 100 and improve the adsorption stability of the entire device. Depending on the operating environment, the material of the sealing ring 135 can be selected from rubber, silicone, polytetrafluoroethylene, or other materials to adjust its high temperature resistance and corrosion resistance.

[0030] The right end of the connecting ring 134 is provided with several snap-fit ​​connectors 1341, and the side wall of the pressing member 14 is provided with snap-fit ​​holes 141 corresponding to the snap-fit ​​connectors 1341, so that the pressing member 14 can snap-fit ​​with the connecting ring 134. With the above arrangement, the pressing member 14 and the connecting ring 134 are more securely fixed and easier to assemble and disassemble.

[0031] The fixing device also includes a connecting cover 16; the inner wall of the first exhaust pipe 113 has an internal thread 1132 on the left side, and the connecting cover 16 can be threadedly connected to the first exhaust pipe 113 through the internal thread 1132; the right side of the pressing member 14 has an outwardly protruding edge 142, and the left side of the connecting cover 16 has a limiting part 161 corresponding to the edge 142 to restrict the movement of the pressing member 14 in the left and right directions.

[0032] The outer side of the second exhaust pipe 131 is provided with a mounting groove 136, and the first spring 132 is disposed in the mounting groove 136 to ensure that the stress provided by the first spring 132 is in the left-right direction, to prevent the first spring 132 from shifting, and to improve the durability of the fixing device. The right end of the first spring 132 abuts against the left end face of the first platform 1131 to provide a continuous reverse elastic force to the negative pressure space 100 and maintain the negative pressure state.

[0033] like Figure 3 As shown, a raised ring 1131a is provided on the outer right side of the first tabletop 1131. Adhesive or double-sided tape is provided within the space enclosed by the raised ring 1131a, forming a strong adhesive adsorption part 114; several through holes 1131b are provided on the side wall of the first tabletop 1131. The through holes 1131b connect the exhaust groove 111 to the negative pressure space 100. With the above configuration, the fixing device can be immediately fixed by the suction cup adsorption part 112, or permanently fixed by adhesive or double-sided tape, increasing its service life and thus improving the flexibility of use and applicability to various application scenarios.

[0034] like Figure 3As shown, a second platform 1313 is provided on the right side of the second exhaust pipe 131. An exhaust port 1311 is provided on the second platform 1313. A one-way valve 15 is installed inside the second exhaust pipe 131 to seal the exhaust port 1311. Through the above arrangement, efficient air discharge from the negative pressure space 100 is achieved, and backflow of external air is avoided, improving the stability of the adsorption and the airtightness of the fixing device.

[0035] like Figure 2 As shown, the one-way valve 15 includes a bracket 151, a support member 152, a plug 153, and a second spring 154. The bracket 151 is disposed inside the second exhaust pipe 131. The support member 152 is movably mounted on the bracket 151. The plug 153 is fixedly disposed on the right side of the support member 152 for sealing the exhaust port 1311. The second spring 154 is at least partially sleeved on the support member 152, with one end abutting against the bracket 151 and the other end abutting against the plug 153, for maintaining the plug 153 in sealing the exhaust port 1311. With the above configuration, the one-way valve 15 has a compact structure and reliable performance, and can effectively control the unidirectional flow of air. The second spring 154 provides a stable return force, ensuring that the exhaust port 1311 closes quickly after exhaust, avoiding the pressure relief problem of the negative pressure space 100. At the same time, this configuration improves the service life and adaptability of the fixing device.

[0036] like Figure 3 As shown, the outer peripheral wall of the outer casing 12 is provided with an external thread 122, and the anti-detachment component 121 is a nut that can be adapted to the thread. The anti-detachment component 121 can be fed and moved relative to the adsorption assembly 11 to clamp and fix the object to be hung. With the above settings, the user can flexibly adjust the position of the anti-detachment component 121 according to the size and shape of the object, thereby improving the applicability and ease of operation of the fixing device. It should be understood that, depending on the actual use requirements, the anti-detachment component 121 can be replaced with a snap-on structure, an elastic clip, or other structures.

[0037] The right end face of the outer casing 12 is flush with the right end face of the adsorption assembly 11 to prevent damage to the adsorption assembly 11 and reduce the erosion of the internal structure by dust or impurities. The interior of the outer casing 12 has a space that allows the adsorption assembly 11 to be fully accommodated. The outer ring of the right end face of the adsorption assembly 11 has a recessed surface. An annular sealant is provided within the recessed surface, forming the suction cup adsorption part 112 to improve the sealing performance of the suction cup adsorption part 112, enabling the device to adapt to different surfaces and maintain a stable adsorption force.

[0038] like Figure 4As shown, the outer casing 12 is basically square-column shaped. A mounting portion 123 is provided on the front end face of the outer casing 12. The mounting portion 123 includes a connector 1231, a positioning spring 1232, a positioning hole 1233, and a friction plate 1234. The connector 1231 has an internal thread. The positioning spring 1232 is positioned close to the connector 1231 to facilitate the positioning of the anti-detachment component 121. The positioning hole 1233 is positioned around the connector 1231 to further guide the anti-detachment component 121. The friction plate 1234 surrounds the positioning hole 1233 to ensure a more secure installation of the anti-detachment component 121. The anti-detachment component 121 is a hook, including a hook body 1211, a rotating shaft 1212, and a fixing member 1213. The hook body 1211 has a through hole in the front-rear direction. The rotating shaft 1212 is engaged in the through hole, and the fixing member 1213 passes through the rotating shaft 1212 and is threadedly connected to the connector 1231. With the above settings, the installation of the fixing device is more convenient and its use is more flexible.
