Description

Technical Field

[0001] This utility model belongs to the field of clothes drying rack technology, specifically a folding clothes drying rack. Background Technology

[0002] Folding clothes racks are portable and space-saving household drying tools, widely applicable to the drying needs of everyday clothes, small home textiles, etc. Whether used on a family balcony or in a rented apartment or small space-constrained environment, they can efficiently utilize vertical space to dry multiple items of clothing. When traveling for business or leisure, they can also be easily folded and packed into a suitcase, solving the drying problem at accommodations.

[0003] The existing clothes drying rack technology has the following disadvantages: For users who frequently travel for business and stay in hotels, the connection between the support rod and the fixed base of the existing folding clothes drying rack requires additional tools such as screwdrivers for disassembly and assembly, which is time-consuming. In addition, the fixing method is limited and has low adaptability to different scenarios. Furthermore, suction cup clothes drying racks often involve directly pulling and squeezing the suction cup body, which is prone to tearing and fatigue. With frequent disassembly and assembly during business trips, the rack will break after one to two months. In order to address the above problems, a folding clothes drying rack is proposed. Utility Model Content

[0004] To address the shortcomings of existing clothes drying racks, a folding clothes drying rack is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The folding clothes rack of this utility model includes a fixed base and folding support rods. The two adjacent folding support rods are hinged together by a connector. The end of the folding support rod near the fixed base is hinged with a connecting plate for quick assembly and disassembly of the folding support rod to the fixed base. The fixed base is provided with screw holes for fixing the folding support rod to the wall.

[0006] Preferably, the fixing seat is integrally formed with a limiting part by stamping. The limiting part includes a first locking protrusion for locking the side wall of the connecting plate to prevent its horizontal displacement, and a second locking protrusion for supporting the bottom end of the connecting plate.

[0007] Preferably, the connector includes two plugs connected by a connecting component, one end of each plug is provided with a gear portion, and the gear portions on the two plugs mesh with each other, and the other end of each plug extends to the inner wall of the end of the folding support rod and is fixed thereon.

[0008] Preferably, the bottom end of the folding support rod is provided with several through holes for hanging clothes. The through holes are diamond-shaped and have an inverted triangle at the bottom.

[0009] Preferably, the mounting base is fitted with a suction cup mechanism for fixing it to the wall through an opening.

[0010] Preferably, the suction cup mechanism includes a housing, a rotating sleeve, a lifting column, a piston, a piston chamber, and a suction cup body. The rotating sleeve and the lifting column cooperate to operate through a linkage structure. When the rotating sleeve rotates, the lifting column can move closer to or further away from the rotating sleeve. When the lifting column moves upward, the air pressure in the piston chamber decreases, causing the suction cup body to adhere and fix to the wall. When the lifting column moves downward, the air pressure in the piston chamber increases, causing the suction cup body to separate and disassemble from the wall.

[0011] Preferably, the linkage structure includes an oblique through groove formed on the periphery of the rotating sleeve, a linkage column fixedly mounted on the lifting column and passing through the oblique through groove, and a longitudinal limiting groove formed on the outer shell. The linkage column is inserted into the longitudinal limiting groove, and several equidistant limiting protrusions are provided on the oblique through groove.

[0012] Preferably, the rotating sleeve is rotatably mounted on the outer shell, and one end of the rotating sleeve extends to the outside of the rotating sleeve and is fixedly provided with an operating sleeve, and the peripheral side of the operating sleeve is provided with friction ribs.

[0013] Preferably, a Y-shaped sealing ring is provided on the periphery of the piston, and a pressure relief hole is provided on the piston chamber for pressure relief. A one-way valve is provided in the pressure relief hole. When the air pressure in the piston chamber decreases, the one-way valve closes, and when the air pressure in the piston chamber increases, the one-way valve opens to allow the piston chamber pressure relief suction cup body to recover.

[0014] Preferably, the suction cup body is provided with a fixed boss, the opening end of the outer shell is provided with a positioning groove that cooperates with the fixed boss, and a sealing protrusion is provided on the inner wall of the piston cavity near the suction cup body.

[0015] The beneficial effects of this utility model are: This utility model provides a folding clothes rack. The limiting part, which is stamped and formed in one piece on the fixed base, cooperates with the connecting plate at the end of the folding support rod to realize the quick assembly and disassembly of the folding support rod and the fixed base without additional tools. The limiting part has high strength and is not easily deformed, ensuring stable fixation. Adjacent folding support rods are hinged through a connector with a gear meshing structure, which can be smoothly unfolded or folded along the hinge point with precise movement trajectory and no jamming. When folded, the gear transmission is synchronized and smooth, without any jamming or dragging, making operation effortless and convenient. When unfolded, the gear meshing limit keeps the support rod in a stretched and straight state, preventing it from tilting and making the load-bearing capacity more stable. At the same time, the volume is greatly reduced when folded, making it compact and space-saving. Whether it is packed into a suitcase for carrying or stored in a small apartment, it is extremely convenient. The suction cup mechanism indirectly drives the suction cup body to deform and generate negative pressure through the cooperation of the piston chamber and the piston. It does not directly contact the suction cup body, avoiding local wear, tearing or fatigue deformation caused by direct force on conventional suction cups, and significantly extending the service life of the suction cup body. At the same time, the linear movement of the piston makes the negative pressure generation more uniform and stable. Furthermore, the linkage structure and limiting convex ball enable multi-level suction adjustment, which can adapt to the hanging needs of clothing of different weights. With the Y-shaped sealing ring and sealing convex ring, a double seal is formed to ensure stable adsorption. The suction cup mechanism and screw hole form a double fixing solution, which is suitable for various wall scenarios, requires no drilling, is suitable for temporary use, and leaves no residue after disassembly.

Detailed Implementation

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Example 1: Please refer to Figures 1-3 The present invention provides a folding clothes rack, which includes a fixed base 1 and folding support rods 2. Two adjacent folding support rods 2 are hinged together by a connector 3. The end of the folding support rod 2 near the fixed base 1 is hinged with a connecting plate 4 for quick assembly and disassembly of the folding support rod 2 to the fixed base 1. The fixed base 1 is provided with screw holes 5 for fixing the folding support rod to the wall. The fixed base 1 has a limiting part 6 integrally formed by stamping. The limiting part 6 includes a first locking protrusion 601 for locking the side wall of the connecting plate 4 to prevent its horizontal displacement, and a second locking protrusion 602 for supporting the bottom end of the connecting plate 4. During operation and installation, the fixed base 1 is first firmly fixed to the wall with screws through the screw holes 5 on the fixed base 1. Then, the connecting plate 4, which is hinged to the end of the folding support rod 2, is aligned with the limiting part 6 of the fixed base 1, so that the side wall of the connecting plate 4 is locked into the gap between the first locking protrusions 601. The first locking protrusions 601 limit the horizontal displacement of the connecting plate 4 by physical blocking. At the same time, the bottom end of the connecting plate 4 is attached to the upper surface of the second locking protrusion 602. The second locking protrusion 602 prevents the connecting plate 4 from moving vertically by supporting force. The folding support rod 2 falls off the wall, thus completing the quick assembly of the folding support rod 2 and the fixed base 1. During disassembly, simply lift the folding support rod 2 away from the fixed base 1, so that the connecting plate 4 is released from the clamping of the first snap-fit ​​protrusion 601 and the support of the second snap-fit ​​protrusion 602, thereby separating the folding support rod 2 from the fixed base 1. Adjacent folding support rods 2 can be folded and stored or unfolded for use by rotating around the hinge point through the hinge structure of the connecting piece 3. The quick assembly and disassembly are achieved through the cooperation of the connecting plate 4 and the limiting part 6, without the need for additional tools, solving the problems of cumbersome assembly and difficult disassembly of traditional clothes racks. In addition, the limiting part 6 adopts a stamping one-piece molding process, avoiding structural weak points caused by welding or assembly, improving the overall strength of the limiting part 6, making it less prone to deformation after long-term use, and ensuring the fixed stability of the connecting plate 4.

[0020] Furthermore, the connector 3 includes two plugs 302 connected by a connecting component 301. One end of each plug 302 is provided with a gear part 303, and the gear parts 303 on the two plugs 302 mesh with each other. The other end of each plug 302 extends to the inner wall of the end of the folding support rod 2 and is fixed thereon. During operation, when the clothes rack needs to be unfolded, the folding support rod 2 is pulled to both sides. The folding support rod 2 drives the plugs 302 fixed thereon to move synchronously. Since the gear parts 303 of the two plugs 302 mesh with each other, when one plug 302 rotates, it will drive the other plug 302 to rotate in the opposite direction through the meshing transmission of the gear teeth. The rotation angle is always symmetrical, so that the adjacent folding support rods 2 can be unfolded smoothly along the hinge point. Moreover, the gear part 303 is an integral gear column structure, which makes the state more stable when rotating. When the clothes rack is fully unfolded, the multiple folding support rods 2 can remain stretched and straight. When it needs to be folded for storage, the same principle applies, so it will not be described in detail here. The folding is flexible and convenient.

[0021] Furthermore, the bottom end of the folding support rod 2 is provided with several through holes 7 for hanging clothes. The through holes 7 are diamond-shaped and have an inverted triangle at the bottom. When in use, clothes are hung into the through holes 7 through the hanger hooks. Since the bottom end of the through hole 7 is an inverted triangle, its opening size gradually decreases from the middle of the hole to the bottom. After the hanger hook is hung, the neck of the hook will be stuck at the narrow end of the inverted triangle. Even if it is blown by a slight wind or the clothes rack shakes, the hook will be difficult to come out from the narrow end of the inverted triangle. At the same time, the diamond-shaped hole design makes the middle opening of the hole larger, which makes it easy to quickly insert the hook. It is also aesthetically pleasing. Multiple through holes 7 are evenly distributed along the bottom end of the folding support rod 2, which can hang multiple clothes at the same time.

[0022] Example 2, please refer to Figure 4Based on Embodiment 1, a suction cup mechanism 8 is added to the fixing base 1. The fixing base 1 is fitted with a suction cup mechanism 8 through a through hole for fixing it to the wall. The suction cup mechanism 8 includes a housing 801, a rotating sleeve 802, a lifting column 803, a piston 804, a piston chamber 8011, and a suction cup body 805. The rotating sleeve 802 and the lifting column 803 cooperate through a linkage structure. When the rotating sleeve 802 rotates, the lifting column 803 can move closer to or further away from the rotating sleeve 802. When the lifting column 803 moves upward, the air pressure in the piston chamber 8011 decreases, causing the suction cup body 805 to adhere and fix to the wall. When the lifting column 803 moves downward, the piston chamber 8011... The increased internal air pressure causes the suction cup body 805 to separate and disassemble from the wall. The linkage structure includes an oblique groove 9 formed on the periphery of the rotating sleeve 802, a linkage column 10 fixedly mounted on the lifting column 803 and passing through the oblique groove 9, and a longitudinal limiting groove 11 formed on the outer shell 801. The linkage column 10 is inserted into the longitudinal limiting groove 11. Several equidistant limiting protrusions 12 are provided on the oblique groove 9. During operation, the suction cup body 805 is pressed tightly against the wall to ensure there are no foreign objects between it and the wall. The rotating sleeve 802 is rotated, and the rotating sleeve 802 drives the oblique groove 9 on the periphery to rotate synchronously. Since one end of the linkage column 10 is fixed on the lifting column 803 and the other end passes through the oblique groove, the linkage column 10 is disassembled. 9 is inserted into the longitudinal limiting groove 11 of the outer shell 801. The longitudinal limiting groove 11 restricts the linkage column 10 from rotating with the oblique through groove 9 and can only move up and down longitudinally. Therefore, when the oblique through groove 9 rotates, its inclined groove wall will generate an upward thrust on the linkage column 10, causing the linkage column 10 to move upward along the longitudinal limiting groove 11. The linkage column 10 drives the lifting column 803 to move upward synchronously. The lifting column 803 pulls the piston 804 to move upward in the piston cavity 8011. The volume of the piston cavity 8011 increases as the piston 804 moves upward, and the air pressure in the cavity decreases accordingly, forming a negative pressure. The suction cup body 805 deforms under the action of external atmospheric pressure and adheres tightly to the wall. At the same time, the limiting protrusion 1 in the oblique through groove 9... 2 will lock the linkage column 10 to prevent it from moving down on its own, maintain the negative pressure state of the piston chamber 8011, and ensure adsorption and fixation. Several limiting protrusions 12 form an adjustable level, which can match different suction power according to the weight of the clothes hanging on the clothes rack, improving the flexibility of use. The suction cup mechanism 8 and screw hole 5 are adapted to different walls, expanding the product's applicable scenarios. The suction cup fixation does not require wall drilling, making it suitable for temporary use scenarios such as rental rooms and hotels. There is no residue after disassembly. Moreover, every time you rotate through the slot of a limiting protrusion 12, you will feel a slight jamming sensation, which can intuitively determine the current suction level without additional observation. After selecting the level, stop rotating, and the limiting protrusion 12 locks the linkage column 10 to maintain the current suction power. During disassembly, the rotating sleeve 802 is rotated in the opposite direction, generating a downward pulling force on the linkage column 10, which drives the linkage column 10 to move downward along the longitudinal limiting groove 11. The linkage column 10 drives the lifting column 803 and the piston 804 to move downward synchronously, the volume of the piston chamber 8011 decreases, and the air pressure inside the chamber increases. When the air pressure increases to a certain value, the suction cup body 805 detaches from the wall and the disassembly is completed.

[0023] Furthermore, the rotating sleeve 802 is rotatably mounted on the outer shell 801, and one end of the rotating sleeve 802 extends to the outside of the rotating sleeve 802 and is fixedly provided with an operating sleeve 806. The operating sleeve 806 is provided with friction ribs 13 on its periphery. When working, when the operating suction cup body 805 is adsorbing and the suction force is adjusted, the user holds the operating sleeve 806 and the friction ribs 13 on it to increase the friction of the hand and avoid slipping.

[0024] Furthermore, a Y-shaped sealing ring 14 is provided on the periphery of the piston 804, and a pressure relief hole 15 is provided on the piston 804 for relieving pressure in the piston chamber 8011. A one-way valve is provided in the pressure relief hole 15. When the air pressure in the piston chamber 8011 decreases, the one-way valve closes; when the air pressure in the piston chamber 8011 increases, the one-way valve opens, allowing the pressure relief suction cup body 805 of the piston chamber 8011 to return to its original position. During operation, when the lifting column 803 drives the piston 804 to move upward in the piston chamber 8011, the volume of the piston chamber 8011 increases, and the air pressure inside the chamber is lower than the external atmospheric pressure. At this time, the one-way valve in the pressure relief hole 15 tightly adheres to the inner wall of the pressure relief hole 15 under the action of the external atmospheric pressure, sealing the pressure relief hole 15 and preventing external air from passing through for pressure relief. The piston chamber 8011 is entered through the hole 15. At the same time, as the piston moves upward, the two lips of the Y-shaped sealing ring 14 on the side of the piston 804 will tightly adhere to the inner wall of the piston chamber 8011, forming a double seal to ensure the stability of the negative pressure state in the piston chamber 8011 and improve the suction force of the suction cup. When the lifting column 803 drives the piston 804 to move downward in the piston chamber 8011, the volume of the piston chamber 8011 decreases, and the air pressure inside the chamber is higher than the external atmospheric pressure. At this time, the high-pressure gas pushes the one-way valve to open, and the high-pressure air in the piston chamber 8011 is quickly discharged to the outside through the pressure relief hole 15, so that the air pressure inside the piston chamber 8011 is quickly balanced with the outside. The cooperation between the one-way valve and the pressure relief hole 15 realizes automatic pressure relief, making separation more convenient.

[0025] Furthermore, the suction cup body 805 is provided with a fixing boss 16, and the opening end of the outer shell 801 is provided with a positioning groove 17 that mates with the fixing boss 16. A sealing ring 18 is provided on the inner wall of the piston chamber 8011 near the suction cup body 805. During operation, when installing the suction cup body 805, the fixing boss 16 on the edge of the suction cup body 805 is aligned with the positioning groove 17 at the opening end of the outer shell 801, and the suction cup body 805 is pushed so that the fixing boss 16 is fully embedded in the positioning groove 17. Adhesive can be added between the two for fixation. At the same time, the interference fit between the fixing boss 16 and the positioning groove 17 can initially prevent air from entering from the connection between the suction cup body 805 and the outer shell 801. Furthermore, when the suction cup body 805 is fixed to the wall, its structure deforms inward, so that the surface of the suction cup body 805 is tightly fitted with the sealing ring 18, forming a second sealing line, further preventing air from entering from the gap between the suction cup body 805 and the piston chamber 8011, and ensuring the sealing integrity of the piston chamber 8011.
