Description

Technical Field

[0001] This utility model relates to the field of towel rack equipment, and in particular to a towel rack. Background Technology

[0002] Towel racks are common bathroom accessories in homes, mainly used to hang towels and other items for easy access in daily life. They not only effectively utilize space and keep the bathroom tidy and organized, but also provide personalized storage solutions based on the needs of different family members.

[0003] As people's demands for convenience and aesthetics in home life continue to increase, traditional towel racks can no longer meet their needs. Traditional towel racks usually need to be installed on the wall by drilling holes or using other fixing methods, which not only damages the wall, but also makes the installation process cumbersome and inconvenient to disassemble and move.

[0004] Therefore, this utility model provides a towel rack. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a towel rack.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a towel rack, comprising a mounting frame, a hanging frame, and an extension frame;

[0007] A negative pressure fixing assembly includes a through hole formed on a mounting bracket, a receiving column fixedly connected to the through hole, a lead screw internally threaded to the receiving column, and a piston fixedly connected to one end of the lead screw near the receiving column;

[0008] A limiting component includes a slot formed inside the mounting frame, a mounting plate is provided on the slot, and sliding grooves are formed at both the upper and lower ends of the mounting plate. An adhesive plate is fixedly connected to the end of the mounting plate away from the slot.

[0009] In a preferred embodiment, a suction cup is fixedly connected to the end of the receiving column away from the lead screw, and the end of the suction cup near the receiving column is fixedly connected to the mounting bracket.

[0010] In a preferred embodiment, a rotating handle is fixedly connected to the end of the lead screw away from the piston.

[0011] In a preferred embodiment, the outer side of the piston is movably connected to the inner wall of the receiving column.

[0012] In a preferred embodiment, the end of the hanger near the adhesive plate is rotatably connected to the top of the mounting bracket.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention utilizes a negative pressure adsorption component. A rotating screw drives a piston to move within a receiving column, expelling air and creating negative pressure. This allows the suction cup to firmly adhere to the wall surface. A limiting component, through the cooperation of a sliding groove and an adhesive plate, restricts the movement of the extension rack and enhances rigidity through frictional damping. This design, through negative pressure adsorption, avoids the problems of traditional towel racks requiring drilling or other fixing methods, preventing damage to the wall surface. Installation and disassembly are more convenient and quick. Furthermore, the synergistic effect of negative pressure adsorption and the limiting component enhances the stability of the towel rack, ensuring it remains secure even when hanging heavy items, thus solving the problem of traditional towel racks easily loosening or falling off.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment provides a technical solution: a towel rack, including a mounting frame 1, a hanging frame 4, and an extension frame 5;

[0027] Mounting rack 1 serves as the basic support structure for the entire towel rack, used to connect and fix other components, providing stability and load-bearing capacity for the towel rack, ensuring that it can be firmly installed on the wall and bear the weight of towels and other items. Hanging rack 4 is used to hang towels and other items, providing hanging points for users to hang towels and other items on it to meet daily use needs. Extension rack 5 can increase the hanging space of the towel rack. The extension rack 5 can be pulled out or retracted as needed to flexibly adjust the length of the towel rack to adapt to the hanging needs of different quantities and sizes of towels.

[0028] The negative pressure fixing assembly 2 includes a through hole 21 formed in the mounting bracket 1. A receiving post 22 is fixedly connected to the through hole 21. A lead screw 23 is threadedly connected to the inside of the receiving post 22. A piston 24 is fixedly connected to the end of the lead screw 23 near the receiving post 22. The outer side of the piston 24 is movably connected to the inner wall of the receiving post 22. A suction cup 25 is fixedly connected to the end of the receiving post 22 away from the lead screw 23. The end of the suction cup 25 near the receiving post 22 is fixedly connected to the mounting bracket 1. A rotating handle 26 is fixedly connected to the end of the lead screw 23 away from the piston 24.

[0029] The through hole 21 serves as the installation location for the receiving column 22, providing fixation and support for it, while also providing a channel for generating negative pressure. The receiving column 22 forms a sealed cavity to house the lead screw 23 and piston 24. The lead screw 23 is threadedly connected, enabling its rotation and the piston 24's movement, thus generating negative pressure. This provides a stable, sealed environment, ensuring effective generation and maintenance of negative pressure. The threaded connection of the lead screw 23 also allows for precise control of the piston 24's movement, improving the stability and controllability of negative pressure generation. The rotation of the lead screw 23 drives the piston 24 within the receiving column 22, changing the internal air pressure and generating negative pressure, causing the suction cup 25 to adhere to the wall. This precise control of the piston 24's movement allows for precise adjustment of the negative pressure, ensuring the towel rack is firmly attached to the wall. The threaded connection of the lead screw 23 also... For easy installation and disassembly, the piston 24 moves within the receiving column 22, expelling or drawing in air, thereby changing the air pressure inside the receiving column 22 and generating negative pressure, causing the suction cup 25 to adhere to the wall. The piston 24 has good sealing performance, effectively expelling or drawing in air from the receiving column 22, ensuring the generation and maintenance of negative pressure. At the same time, the movement of the piston 24 is relatively smooth, without problems such as jamming or air leakage. The suction cup 25 uses negative pressure to adhere to the wall, providing adsorption and fixing force for the towel rack, allowing it to be firmly installed on the wall without drilling or using other fixing methods. The drill-free design will not damage the wall surface and is suitable for various smooth wall surfaces, such as tiles and glass. Installation is convenient and quick, and it can be disassembled and moved at any time, allowing users to adjust the installation position of the towel rack as needed. The rotating handle 26 is the rotating operating component of the lead screw 23, allowing users to rotate the lead screw 23 to control the movement of the piston 24 and the generation of negative pressure.

[0030] like Figures 1-3 As shown, the limiting component 3 includes a slot 31 opened inside the mounting frame 1. The end of the extension frame 5 near the slot 31 is rotatably connected to the bottom end of the mounting frame 1. A mounting plate 32 is provided on the slot 31. Sliding grooves 33 are opened at both the upper and lower ends of the mounting plate 32. An adhesive plate 34 is fixedly connected to the end of the mounting plate 32 away from the slot 31. The end of the hanger 4 near the adhesive plate 34 is rotatably connected to the top end of the mounting frame 1.

[0031] The slot 31 is the mounting position for the mounting plate 32, providing fixation and support for the mounting plate 32, while limiting the direction of movement of the mounting plate 32, ensuring that the mounting plate 32 slides stably within the slot 31, thus acting as a limit. The mounting plate 32 is installed in the slot 31 and cooperates with the extension frame 5 or other components through the sliding groove 33, serving as a limit and support. Sliding grooves 33 are provided at both the upper and lower ends of the mounting plate 32 to guide and limit the movement of the extension frame 5, preventing the extension frame 5 from over-extending or retracting. The sliding grooves 33 are located at both the upper and lower ends of the mounting plate 32 to guide and limit the movement of the extension frame 5. The shape and size of the sliding grooves 33 match the sliding components of the extension frame 5, ensuring that the extension frame 5 can move within the sliding grooves 33. Smooth sliding while preventing the extension frame 5 from detaching from the slide groove 33. The adhesive plate 34 is fixedly connected to the end of the mounting plate 32 away from the slot 31 to enhance the adhesion between the mounting plate 32 and the wall, preventing the mounting plate 32 from loosening or falling off during use. The material of the adhesive plate 34 has good adhesion and durability, and can be firmly pasted to the wall. The limiting component 3 is placed on the bottom side of the negative pressure fixing component 2. In this way, when the towel is hung on the hanger 4 and the extension frame 5, the force generated will squeeze towards the limiting component 3 and exert an outward pulling force on the negative pressure fixing component 2. Thus, through the large contact area between the mounting plate 32 and the adhesive plate 34, the contact friction is increased, thereby making the entire device stable.

[0032] Working principle:

[0033] like Figure 1 - Figure 4 As shown:

[0034] In use: First, fix the adhesive plate 34 to the front, then align the mounting plate 32 with the adhesive plate 34 and attach it. Next, slide the mounting plate 32 into the slot 31 on the mounting bracket 1. Then, rotate the handle 26 of the negative pressure fixing assembly 2, causing the lead screw 23 to rotate threadedly within the receiving column 22. This pushes the piston 24 to move linearly along the inner wall of the receiving column 22 towards the suction cup 25. The advancement of the piston 24 compresses the air inside the receiving column 22 through the through hole 21, creating a sealed negative pressure space between the suction cup 25 and the wall. As the lead screw 23 continues to screw in, the suction cup 25 generates strong adhesion under negative pressure, firmly fixing the mounting bracket 1 to the wall. Under load, the weight of the suspended object exerts a pulling force on the top of the mounting bracket 1 through the hanger 4. This force is transmitted through the mounting bracket 1 to the negative pressure fixing component 2, forming a reverse pull and enhancing the sealing of the suction cup 25. On the other hand, the weight is converted into a compressive force on the limiting component 3 through the rotating shaft of the extension bracket 5, causing the sliding groove 33 of the mounting plate 32 to produce a wedge-shaped locking effect with the extension bracket 5. At the same time, the contact area between the adhesive plate 34 and the wall increases, suppressing device displacement through friction damping effect. The synergistic effect of the two components forms a balance, achieving high-load stable suspension without drilling.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
