Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly to a hanging member storage and fixing device. Background Art

[0002] With the continuous improvement of people's requirements for space utilization and life convenience, various hanging member storage devices are widely used in places such as homes and offices. The common fixing methods currently on the market mainly include two types: punch-free suction cups and nail-free strong adhesives.

[0003] The nail-free strong adhesive can provide relatively stable bonding strength after curing and will not damage the wall surface. However, its installation process requires the assistance of auxiliary materials and usually takes several hours or even longer to fully cure, which is not conducive to the immediate installation and use of the hanging member. At the same time, it is difficult to remove or reposition the nail-free strong adhesive after curing. If the user wants to adjust the position of the hanging member during the installation process, additional tools or removal steps are required, greatly limiting the flexibility of use.

[0004] In contrast, suction cup products are favored by users because they do not damage the wall surface and are easy to operate, allowing for immediate sticking and use. However, after traditional suction cups are used for a period of time, they often gradually lose their adsorption ability due to suction cup aging, air leakage, or environmental factors, resulting in the hanging member falling off. In addition, such suction cups often cannot be firmly adsorbed again after falling off, making their reusability poor.

[0005] A Chinese utility model patent (Publication No.: CN222102536U, Publication Date: December 3, 2024), a suction cup mechanism and a wall-mounted storage device, both include: a suction cup main body, the suction cup main body is provided with an installation pipe portion for passing through a preset installation hole of the storage hanging member, a detachment prevention member is detachably installed on the outer peripheral wall of the installation pipe portion, and an installation gap for preventing the storage hanging member from detaching is defined between the detachment prevention member and the suction cup main body. The suction cup main body has an adsorption surface in contact with the surface to be installed. An exhaust passage is provided in the suction cup main body, the inlet of the exhaust passage is located on the adsorption surface, a piston member is movably arranged in the exhaust passage, a sealing ring cooperating with the inner wall of the exhaust passage is installed on the piston member, and the piston member is connected to an operating rod passing through the installation pipe portion; the user presses the operating rod to drive the piston member to compress the space in the exhaust passage so that the exhaust passage is in a vacuum or near-vacuum state. Through the above structure, it is both convenient to replace the suction cup mechanism and can stably adsorb the suction cup mechanism on the wall, improving the convenience and stability of use. This patent uses the method of compressing the exhaust by the piston member, and the exhaust is difficult. At the same time, if the suction cup leaks air or is affected by environmental factors and gradually loses its adsorption ability after exhausting, reinstallation is required, which is very inconvenient.

[0006] In summary, the existing ways of hanging accessory storage and fixation have certain limitations in terms of convenience, durability, and adjustability. To meet people's needs for efficient space utilization and flexible installation, a hanging accessory storage and fixation solution that combines stability and removable adjustability is required.

[0015] Further, the one-way valve includes a bracket, a support member, a plug and a second spring; the bracket is arranged in the second exhaust pipe; the support member is movably penetrated through the bracket; the plug is fixedly arranged on the right side of the support member and is used to close the exhaust hole; the second spring is at least partially sleeved on the support member, one end of the second spring abuts against the bracket, and the other end abuts against the plug, and is used to maintain the plug to close the exhaust hole.

Detailed Embodiments

[0024] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] At the same time, in order to clearly illustrate the technical solutions of this application, the upper side, lower side, front side, rear side, left side, and right side are also defined as shown in Figure 1 the figure.

[0026] As shown in Figures 1 to 3 the figure, this application provides a hanging part storage and fixing device. The fixing device includes: an adsorption component 11, a piston part 12, a one - way valve 13, a pressing part 14, and an outer shell 15 for decorative fixation.

[0027] Specifically, an exhaust groove 111 is provided on the right end face of the adsorption assembly 11, and a suction cup adsorption part 112 is provided around the periphery of the exhaust groove 111. A first exhaust pipe 113 extending in the left-right direction is provided in the middle of the adsorption assembly 11. A first table surface 1131 is provided at the right end of the first exhaust pipe 113, and a strong glue adsorption part 114 is provided on the right end face of the first table surface 1131.

[0028] The piston member 12 is movably arranged in the first exhaust pipe 113, and a second exhaust pipe 121 extending in the left-right direction is provided in the middle. An exhaust hole 1211 is provided on the right side of the second exhaust pipe 121. A negative pressure space 100 communicating with the exhaust groove 111 is formed between the piston member 12 and the first exhaust pipe 113. A first spring 122 is provided in the negative pressure space 100. The first spring 122 can maintain the negative pressure state of the negative pressure space 100.

[0029] The one-way valve 13 is at least partially arranged in the second exhaust pipe 121 and can limit the air from flowing into the first exhaust pipe 113 through the exhaust hole 1211. The pressing member 14 is at least partially arranged on the right side of the piston member 12, and the pressing member 14 abuts against the piston member 12. When the pressing member 14 drives the piston member 12 to move to the right, the piston member 12 compresses the air in the negative pressure space 100, and the air pressure is greater than the resistance of the one-way valve 13, enabling the air to discharge from the negative pressure space 100 through the one-way valve 13. The housing 15 is at least partially sleeved on the adsorption assembly 11 and the pressing member 14, and an anti-detachment member 151 for restricting the detachment of the object to be hung is provided on the outer peripheral wall.

[0030] The fixing device realizes the quick adsorption and stable fixation of the hanging piece by providing the exhaust groove 111 and the suction cup adsorption part 112 in the adsorption assembly 11 and driving the piston member 12 to discharge air to form the negative pressure space 100 through the pressing member 14. At the same time, the fixing device combines the double advantages of the suction cup and the nail-free strong glue; users can choose to use the suction cup for immediate fixation according to needs, or after using it for a period of time, increase the attraction by pressing to evacuate the air and consolidate the fixation of the suction cup. When the final position is determined, users can also choose to use the nail-free strong glue for permanent fixation to increase the service life of the product. In addition, the device does not require complex rotation or locking operations, and only simple pressing is required to complete the adsorption, greatly reducing the use difficulty and improving the use efficiency.

[0031] As Figure 1 shown, an installation hole 115 is provided in the middle of the first table surface 1131, so that when the suction cup and the nail-free strong glue fail, the fixing device can be fixed by means of screw fixation, improving the installation stability of the fixing device.

[0032] As Figure 2As shown, the piston member 12 includes a piston ring 123 and a connecting ring 124. The piston ring 123 and the connecting ring 124 are fixedly connected or integrally formed so that the one-way valve 13 is sealed within the piston member 12 to achieve the one-way exhaust function. The connecting ring 124 abuts against the pressing member 14. A sealing ring 125 is provided on the piston member 12 that can cooperate with the inner wall of the first exhaust pipe 113. The sealing ring 125 can reduce the gas leakage in the negative pressure space 100 and improve the adsorption stability of the entire device. Among them, according to the use environment, the material of the sealing ring 125 can be selected from rubber, silica gel, polytetrafluoroethylene or other materials to adjust its high temperature resistance and corrosion resistance.

[0033] A number of clamping joints 1241 are provided at the right end of the connecting ring 124, and clamping holes 141 corresponding to the clamping joints 1241 are provided on the side wall of the pressing member 14 so that the pressing member 14 can be clamped and cooperated with the connecting ring 124. Through the above settings, the fixing of the pressing member 14 and the connecting ring 124 is more reliable and the disassembly is more convenient.

[0034] The fixing device further includes an adapter cover 16; an internal thread 1132 is provided on the left side of the inner wall of the first exhaust pipe 113, and the adapter cover 16 can be threadedly connected to the first exhaust pipe 113 through the internal thread 1132; an outwardly protruding edge 142 is provided on the right side of the pressing member 14, and a limiting portion 161 corresponding to the edge 142 is provided on the left side of the adapter cover 16 to limit the movement of the pressing member 14 in the left-right direction.

[0035] An installation groove 126 is provided on the outer side of the second exhaust pipe 121, and the first spring 122 is arranged in the installation groove 126 to ensure that the stress provided by the first spring 122 is in the left-right direction, avoid the deviation of the first spring 122, and improve the durability of the fixing device. The right end of the first spring 122 abuts against the left end face of the first table surface 1131 to provide a continuous reverse elastic force for the negative pressure space 100 and maintain the negative pressure state.

[0036] As Figure 3 shown, a convex ring 1131a is provided on the outer circumference of the right side of the first table surface 1131. An adhesive or double-sided tape is provided in the space surrounded by the convex ring 1131a to form a strong adhesive adsorption portion 114; a number of through holes 1131b are provided on the side wall of the first table surface 1131. The through holes 1131b communicate the exhaust groove 111 with the negative pressure space 100. Through the above settings, the fixing device can be instantaneously fixed through the suction cup adsorption portion 112 or permanently fixed through the adhesive or double-sided tape, increasing the service cycle, thereby improving the flexibility of the fixing device in use and its applicability to various use scenarios.

[0037] As Figure 3As shown, a second table surface 1212 is provided on the right side of the second exhaust pipe 121. Exhaust holes 1211 are provided on the second table surface 1212. A one-way valve 13 is disposed in the second exhaust pipe 121 for closing the exhaust holes 1211. Through the above arrangement, efficient discharge of air in the negative pressure space 100 is achieved, and reverse flow of external air is avoided, improving the adsorption stability and the airtightness of the fixing device.

[0038] As Figure 2 shown, the one-way valve 13 includes a bracket 131, a support member 132, a plug 133, and a second spring 134. The bracket 131 is disposed in the second exhaust pipe 121. The support member 132 is movably inserted through the bracket 131. The plug 133 is fixedly disposed on the right side of the support member 132 for closing the exhaust holes 1211. The second spring 134 is at least partially sleeved on the support member 132. One end of the second spring 134 abuts against the bracket 131, and the other end abuts against the plug 133 for maintaining the plug 133 to close the exhaust holes 1211. Through the above arrangement, the one-way valve 13 has a compact structure and reliable performance, and can effectively control the one-way flow of air. The second spring 134 provides a stable return force to ensure that the exhaust holes 1211 are quickly closed after exhaust, avoiding the problem of pressure relief in the negative pressure space 100. At the same time, this arrangement improves the service life and adaptability of the fixing device.

[0039] As Figure 3 shown, an external thread 152 is provided on the outer peripheral wall of the housing 15, and the anti-detachment member 151 is provided as a nut adaptable to the thread. The anti-detachment member 151 can be fed and moved relative to the adsorption assembly 11 to clamp and fix the object to be hung. Through the above arrangement, the user can flexibly adjust the position of the anti-detachment member 151 according to the size and shape of the hanging object, thereby improving the applicability and operation convenience of the fixing device. It should be understood that according to actual use requirements, the anti-detachment member 151 can be replaced with a snap structure, an elastic clip or other structures.

[0040] The right end face of the housing 15 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 dust or impurities on the internal structure. A space is provided inside the housing 15 for the adsorption assembly 11 to be completely received. A recessed surface is provided on the outer ring of the right end face of the adsorption assembly 11. An annular sealant is provided in the recessed surface, and the annular sealant forms a suction cup adsorption portion 112 to improve the airtightness of the suction cup adsorption portion 112, enabling the device to adapt to different surfaces and maintain a stable adsorption force.
