Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a suction cup armrest. Background Technology

[0002] In the existing technology, in order to make it easier for the elderly to get up and lie down, handrails are installed on the walls in the bathroom or bedroom. In order not to damage the wall, most handrails on the market are suction cup handrails, including handrail bars and suction cups at both ends of the handrail bars, which are attached to the wall for installation and fixation.

[0003] Existing suction cup handrails are fixed with suction cups, which are used to adhere to the wall. Although this structure does not damage the wall, the suction cup handrails need to be left to stand for 5-24 hours after installation to ensure that they are completely stable. The waiting time is long, and the suction cups are not detachable from the handrail. Once the suction cups lose their adhesion, they cannot be replaced, which poses a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a suction cup armrest with a detachable connection between the suction cup assembly and the armrest trunk. An adhesive is provided on the inside of the suction cup, which uses the double adsorption of the adhesive and the suction cup to enhance the adsorption force and effectively reduce the waiting time. It can be used immediately after installation.

[0005] The technical solution of this utility model is as follows: A suction cup handrail includes a handrail rod and suction cup assemblies installed at both ends of the handrail rod. The suction cup assembly includes a connecting cover and suction cup components. The connecting cover is connected to the handrail rod. A connecting chamber is provided on one end of the connecting cover facing the handrail rod. A connecting rod is provided on the handrail rod. The connecting rod is inserted into the connecting chamber and connected to the connecting cover by screws. The connecting cover has an installation chamber that runs through it in the front-back direction. One side of the suction cup component extends into the installation chamber and connects to the connecting cover. An adhesive is provided on the other side of the suction cup component, and the end face of the adhesive is exposed outside the suction cup component. An exhaust channel is provided in the middle of the suction cup component. A piston component is provided in the exhaust channel. A pressing component is provided in the installation chamber along its through direction. The end of the pressing component is exposed outside the installation chamber. The piston component is connected to the pressing component and slides in the exhaust channel under the drive of the pressing component.

[0006] By adopting the above technical solution, the detachable connection between the outer cover and the handrail allows for replacement of the suction cup components when their adhesion weakens. Furthermore, only the suction cup components need to be replaced, rather than the entire unit. The connection structure between the outer cover and the handrail is simple, easy to assemble and disassemble, and structurally robust. The connecting rod is smaller than the handrail, and after the connecting rod is inserted into the connecting chamber, the surface of the handrail is flush with the outer surface of the connecting chamber, resulting in smoother, stepless operation. Adhesive is provided on the inner side of the suction cup components to enhance their adhesion to the wall. By pushing the pressing component into the mounting chamber, the piston moves within the exhaust channel, expelling air and creating a vacuum or near-vacuum state within the exhaust channel. This allows the suction cup to be stably adhered to the wall, and the adhesive, combined with the adhesive, provides even stronger adhesion.

[0007] Further features of this invention: The connecting cover includes a separate cover body and a cover plate. The connecting chamber and the mounting chamber are both located on the cover body. The cover plate covers the front end of the mounting chamber. The cover plate has insertion blocks and through connecting posts at both ends. The cover body has insertion grooves and connecting holes. The connecting posts and connecting holes are correspondingly arranged and connected by screws. The insertion blocks are inserted into the insertion grooves.

[0008] With the above-mentioned further design, the split design facilitates the disassembly and assembly of components such as the pressing parts and suction cups in the installation chamber. After the installation is completed, the cover plate is installed. First, the plug block at one end of the cover plate is inserted into the plug groove for positioning, and then the other end is fixed with screws. The installation position is accurate and the structure is firm.

[0009] A further feature of this invention is that the cover plate is provided with a guide post extending into the installation cavity, the guide post being arranged through it in the front-back direction, the pressing member extending through the guide post into the installation cavity, the pressing member being provided with a positioning hook, and the side wall of the guide post being provided with a positioning groove along the sliding direction of the pressing member, the positioning hook being located in the positioning groove.

[0010] The above-mentioned further design can guide the pressing component, making it slide smoothly and without deviation. The positioning hook is located in the positioning groove, which can position the pressing component and prevent it from detaching from the connecting cover after being installed in the installation chamber.

[0011] A further feature of this invention is that the suction cup component has an annular constriction portion, and the inner wall of the mounting cavity has a connecting boss along its circumference. The annular constriction portion has an outwardly extending extension piece, the annular constriction portion is located inside the connecting boss, and the extension piece rests on the connecting boss.

[0012] With the above-mentioned further design, the structure is simple and easy to assemble and disassemble.

[0013] A further feature of this invention is as follows: a limiting member is provided in the installation chamber, the limiting member is located on the connecting boss, the limiting member is provided with several limiting blocks, the annular constricted portion is provided with several limiting grooves, each limiting block is inserted into the corresponding limiting groove, the limiting member is also provided with an insert block, the side wall of the installation chamber is provided with a slot, and the insert block is inserted into the slot.

[0014] With the above-mentioned further design, the limiting component can restrict the rotation of the suction cup component, making its structure stable and firm during installation. The limiting block is installed and fixed by the cooperation of the insert and the slot. The structure is simple and requires no other tools for installation, making it convenient and quick.

[0015] A further improvement of this invention is that the piston is provided with a sealing element that cooperates with the side wall of the exhaust channel.

[0016] The above-mentioned further design ensures the airtightness of the exhaust channel, effectively expels air, and prevents air from entering the exhaust channel during use.

[0017] A further improvement of this utility model: the pressing component includes a pressing rod and a pressing seat. The pressing seat is located between the pressing rod and the piston component. One end of the pressing rod is exposed outside the mounting cavity, and the other end abuts against the pressing seat. The piston component has a connecting hook in the middle, and the pressing seat has a connecting groove. The connecting hook is hooked into the connecting groove, and the pressing seat presses against the sealing component.

[0018] With the above-mentioned further design, the connection structure is simple and easy to disassemble and assemble. The sealing element is located between the pressure seat and the piston to clamp and improve the sealing performance.

[0019] A further feature of this invention is that the mounting cavity is provided with several limiting plates, each of which is located on the front side of the suction cup component.

[0020] With the above-mentioned further design, the suction cup component can be positioned during installation, and the connection to the outer cover can be strengthened. Attached Figure Description
