[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A portable concealed clothes drying rack includes a trough frame with symmetrically distributed sliding grooves inside. Folding arms are rotatably connected to both ends of the trough frame, and long arms are rotatably connected to opposite sides of the two sets of folding arms. One end of the long arm is slidably connected to the two sets of sliding grooves via a sliding rod, and a positioning sleeve is rotatably connected to the other end of the long arm. A fixing tube is sleeved between the two sets of positioning sleeves, and extension tubes are inserted into both ends of the fixing tube.

[0007] A further embodiment of this invention is that the groove frame, slide, long arm, folding arm, extension tube, and fixed insertion tube are all made of aluminum alloy.

[0008] A further embodiment of this invention is that the groove frame and the slide are integrally manufactured.

[0009] A further aspect of this invention is that the surface of the groove is provided with a wear-resistant coating.

[0011] A further embodiment of this invention is that a limiting head is connected to the end of the extension tube away from the fixed insertion tube.

[0012] A further embodiment of this invention is that the extension tube is threadedly connected to the limiting head.

[0013] A further embodiment of this invention is that the positioning sleeve is a plastic product.

[0014] A further embodiment of this invention is that the port of the fixed insertion tube is fitted with a limiting sleeve, and two sets of positioning sleeves are disposed between the two sets of limiting sleeves.

[0015] A further embodiment of this invention is that the limiting sleeve is a rubber product.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model extends service life: This portable invisible clothes drying rack, through its unique structural design, abandons the traditional folding method where the long arm slides on the drying rod. The long arm slides within a groove via a sliding rod and rotates in coordination with the folding arm, positioning sleeve, and other components to achieve folding.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 2 to 3 As shown, a convenient concealed clothes drying rack includes a trough frame 1, with symmetrically distributed sliding grooves 2 connected inside the trough frame 1. Folding arms 4 are rotatably connected to both ends of the trough frame 1, and long arms 3 are rotatably connected to opposite sides of the two sets of folding arms 4. One end of the long arm 3 is slidably connected to the two sets of sliding grooves 2 via a sliding rod, and the other end of the long arm 3 is rotatably connected to a positioning sleeve 8. A fixing insert 9 is sleeved between the two sets of positioning sleeves 8, and extension tubes 6 are inserted into both ends of the fixing insert 9.

[0027] Working principle

[0028] Unfolding principle

[0029] Initial drive: The user first applies force to the folding arm 4, causing it to begin rotating outward around the rotational connection point at the inner end of the slot frame 1. The folding arm 4, as the initial drive component, drives the long arm 3, which is rotatably connected to it, to move synchronously.

[0030] Long arm sliding and rotation: During the outward rotation of the long arm 3, the sliding rod connected to one end slides upward along the symmetrically distributed sliding grooves 2 inside the trough frame 1. This sliding process not only provides a track constraint for the rotation of the long arm 3, but also ensures the stability of the long arm 3 when it is extended. The long arm 3 slides upward while rotating outward, expanding the clothes drying space.

[0031] Fixed insertion tube deployment: As the long arm 3 rotates, the positioning sleeve 8, which is rotatably connected to the other end of the long arm 3, also rotates. The fixed insertion tube 9, which is sleeved between the two positioning sleeves 8, gradually unfolds to a horizontal state under the action of the positioning sleeves 8.

[0032] Extension tube extension: After the fixed insertion tube 9 reaches the horizontal position, the user pulls the extension tubes 6 at both ends of the fixed insertion tube 9 outwards. At this point, the clothes rack is fully extended and can be used to hang clothes.

[0033] Folding principle

[0034] Extension tube storage: After use, the user first pushes the extension tube 6 into the fixed insertion tube 9 so that it is stored in both ends of the fixed insertion tube 9, shortening the overall length of the clothes drying rod.

[0035] The folding arm drives the movement: the user pushes the folding arm 4 to rotate inward towards the groove frame 1, and the folding arm 4 drives the long arm 3 to rotate inward towards the folding arm 4. At this time, the slide bar at one end of the long arm 3 slides downward along the slide groove 2, providing a reverse motion trajectory.

[0036] Fixed insertion tube folding: The rotation of the long arm 3 drives the positioning sleeve 8 to rotate, and the positioning sleeve 8 in turn drives the fixed insertion tube 9 to rotate inward of the long arm 3. As the folding arm 4 continues to rotate, the long arm 3, the folding arm 4 and the fixed insertion tube 9 gradually fold into the slot frame 1, achieving invisible storage and reducing space occupation.

[0037] Example 2

[0038] like Figures 2 to 3 As shown, a convenient concealed clothes drying rack includes a trough frame 1, with symmetrically distributed sliding grooves 2 connected inside the trough frame 1. Folding arms 4 are rotatably connected to both ends of the trough frame 1, and long arms 3 are rotatably connected to opposite sides of the two sets of folding arms 4. One end of the long arm 3 is slidably connected to the two sets of sliding grooves 2 via a sliding rod, and the other end of the long arm 3 is rotatably connected to a positioning sleeve 8. A fixing insert 9 is sleeved between the two sets of positioning sleeves 8, and extension tubes 6 are inserted into both ends of the fixing insert 9.

[0039] The trough frame 1, slide 2, long arm 3, folding arm 4, extension tube 6, and fixed insertion tube 9 are all made of aluminum alloy.

[0040] The advantages of the above settings are:

[0041] Lightweight and portable, easy to operate

[0042] The low density of aluminum alloy significantly reduces the overall weight of the clothes rack. This means users need to exert less effort when unfolding and folding the rack, making operation easier and more convenient. This is especially beneficial for the elderly and children, reducing the difficulty of use and improving the user experience. Furthermore, the lighter weight also simplifies installation, reducing the load-bearing requirements on the wall or ceiling.

[0043] Corrosion resistant, extending service life

[0044] Aluminum alloys possess excellent corrosion resistance, effectively resisting the erosion of humid environments and various chemicals. During use, clothes racks inevitably come into contact with water and corrosive substances such as detergents. The aluminum alloy material ensures that the clothes rack will not be damaged by corrosion during long-term use, greatly extending the product's lifespan and reducing replacement costs for users.

[0045] High strength and stable structure

[0046] Despite its lightweight nature, aluminum alloy possesses high strength, enabling it to withstand significant weight. This allows the clothes rack to maintain a stable structure even when carrying a large amount of clothing, preventing deformation or damage and ensuring safety during use.

[0047] The trough frame 1 and the slide 2 are made as a single piece.

[0048] The advantages of the above settings are:

[0049] Enhance structural stability

[0050] The trough frame 1 and the slide rail 2 are manufactured as a single piece, eliminating any potential seams between them and avoiding structural weaknesses caused by splicing processes. When the long arm 3 slides within the slide rail 2 via the sliding rod, and when the folding arm 4 drives the long arm 3 to complete the folding action, the integrated trough frame 1 and slide rail 2 can evenly distribute the stress. This feature effectively prevents localized deformation or damage to the trough frame 1 and slide rail 2, significantly improving the durability and load-bearing capacity of the clothes rack compared to traditional spliced ​​structures, ensuring stable performance even under frequent use.

[0051] Reduce processing and installation difficulty

[0052] The integrated manufacturing process greatly simplifies the production flow, reducing the processing and assembly steps of the trough frame 1 and slide 2 as independent components. This lowers processing costs and shortens the production cycle. During installation, the elimination of complex splicing and alignment operations makes the clothes rack installation much easier. Installers do not need to spend a lot of time positioning and securing the trough frame 1 and slide 2, reducing various problems caused by improper installation. This not only improves production efficiency but also provides users with a more convenient installation experience and reduces the risk of installation errors.

[0053] The surface of the slide 2 is coated with a wear-resistant coating.

[0054] The advantages of the above settings are:

[0055] Reduce component wear and extend service life

[0056] In daily use of the portable concealed clothes drying rack, the long arm 3 slides repeatedly within the sliding groove 2 via a sliding rod. The wear-resistant coating on the surface of the sliding groove 2 effectively reduces the coefficient of friction between the sliding rod and the sliding groove 2, minimizing wear caused by sliding friction. Over time, even after numerous unfolding and folding operations, the sliding groove 2 maintains good structural and dimensional accuracy, and the sliding rod will not affect normal use due to excessive wear. This significantly extends the service life of the sliding groove 2, the sliding rod, and even the entire clothes drying rack.

[0057] Reduce maintenance costs

[0058] The presence of the wear-resistant coating reduces the frequency of repair or replacement of the groove 2 due to wear. Compared to a groove without a wear-resistant coating, it eliminates the need for frequent inspections and repairs during long-term use, reducing replacement costs due to component damage. This not only saves economic costs but also saves users significant time and effort associated with maintenance, improving the stability and sustainability of the clothes rack's use.

[0059] Ensure smooth operation

[0060] Wear and tear often leads to unevenness on the surface of the slide rail 2, affecting the smoothness of the sliding rod. The wear-resistant coating, however, maintains the smoothness of the slide rail 2 surface, ensuring the rod slides smoothly within the rail. Whether unfolding the clothes rack to dry clothes or folding it for storage, there will be no jamming or obstruction, greatly improving the user experience.

[0061] A first damping shaft is provided at the rotatable connection between the folding arm 4 and the tank frame 1, a second damping shaft is provided at the rotatable connection between the long arm 3 and the folding arm 4, and a third damping shaft is provided at the rotatable connection between the long arm 3 and the positioning sleeve 8.

[0062] The advantages of the above settings are:

[0063] Precise operation and convenient positioning

[0064] During the unfolding or folding of the clothes rack, the first damping pivot provides moderate resistance to the rotation of the folding arm 4 and the tray frame 1, allowing the user to precisely control the rotation angle of the folding arm 4 and stop it at any desired position. Similarly, the second damping pivot makes the adjustment of the rotation angle of the long arm 3 and the folding arm 4 more flexible, and the third damping pivot assists the positioning sleeve 8 in precisely rotating and positioning the long arm 3. This allows the positions of each component of the clothes rack to be precisely set according to the user's needs during adjustment, greatly improving operational convenience.

[0065] Improve stability and ensure security

[0066] When the clothes rack is in its unfolded state and carrying clothes, the damping force generated by the three damping pivots effectively prevents the folding arm 4, the long arm 3, and the positioning sleeve 8 from rotating arbitrarily due to external forces or vibrations. For example, when drying clothes in a windy environment, the damping pivots can prevent the clothes rack from swaying in the wind and causing clothes to fall off. The stable structural design ensures the safety of the clothes rack during use.

[0067] Reduce impact and extend lifespan

[0068] When unfolding and folding the clothes rack, the damping pivot can slow down the rotation speed of the components, avoiding collisions and impacts caused by excessive speed. Taking the folding arm 4 as an example, the first damping pivot prevents it from rapidly impacting the tray frame 1, reducing the risk of component damage, extending the service life of the folding arm 4, the tray frame 1, and other related components, and reducing the economic costs caused by frequent component replacements.

[0069] Example 3

[0070] like Figures 2 to 3 As shown, a convenient concealed clothes drying rack includes a trough frame 1, with symmetrically distributed sliding grooves 2 connected inside the trough frame 1. Folding arms 4 are rotatably connected to both ends of the trough frame 1, and long arms 3 are rotatably connected to opposite sides of the two sets of folding arms 4. One end of the long arm 3 is slidably connected to the two sets of sliding grooves 2 via a sliding rod, and the other end of the long arm 3 is rotatably connected to a positioning sleeve 8. A fixing insert 9 is sleeved between the two sets of positioning sleeves 8, and extension tubes 6 are inserted into both ends of the fixing insert 9.

[0071] The end of the extension tube 6 away from the fixed insertion tube 9 is connected to the limiting head 5.

[0072] The advantages of the above settings are:

[0073] Significantly improves ease of use

[0074] Traditional clothes racks often lack a reliable point of leverage when pulling out the extension tube, making it difficult for users to operate. However, the design of the limit head 5 provides a reliable point of leverage. When the extension tube 6 needs to be pulled out, the user can directly grasp the limit head 5 and apply force easily, without needing to spend extra effort finding a suitable grip position. This greatly simplifies the operation of pulling out the extension tube 6, saves time, and even people with less strength can easily complete the pulling action.

[0075] Improve user experience

[0076] When pulling out the extension tube, the limit head 5 allows for more precise control of the extension tube 6. Users can precisely control the extension length of the extension tube 6 according to their actual drying needs, avoiding repeated adjustments due to over- or under-extension. This precise control enhances the user's sense of control over the clothes rack's operation, creating a smoother and more comfortable user experience in conjunction with the overall operation flow.

[0077] The extension tube 6 is threadedly connected to the limiting head 5.

[0078] The advantages of the above settings are:

[0079] A secure connection ensures safe use.

[0080] The threaded connection has excellent self-locking properties, ensuring a tight fit between the limiting head 5 and the extension tube 6. During use, even under significant pulling or shaking, the limiting head 5 is unlikely to loosen or detach, ensuring the extension tube 6 remains in a stable working state. This robust connection effectively prevents clothes from falling due to the limiting head 5 detaching, protecting user safety and enhancing the reliability of the clothes rack.

[0081] Easy to install and reduces operating difficulty

[0082] Compared to other connection methods, threaded connections are simple and easy to install. Users simply align the limiting head 5 with the threaded port of the extension tube 6 and rotate it clockwise to easily complete the installation. No professional tools or complicated procedures are required, greatly reducing installation difficulty and saving time. Even users without professional installation experience can quickly complete the installation.

[0083] Easy to maintain and replace

[0084] When the limiting head 5 becomes damaged or worn due to long-term use, it can be easily disassembled and replaced by the user via the threaded connection. Similarly, when maintaining or cleaning the extension tube 6, the limiting head 5 can also be easily disassembled, facilitating comprehensive maintenance of the end of the extension tube 6. This convenient maintenance and replacement method reduces the maintenance cost of the clothes rack and extends its service life.

[0085] The positioning sleeve 8 is made of plastic.

[0086] The advantages of the above settings are:

[0087] Low cost, enhancing product competitiveness

[0088] The wide availability of plastic raw materials and mature production processes significantly reduce the manufacturing cost of the positioning sleeve 8. Compared to metal positioning sleeves, plastic products can effectively control production costs while ensuring the basic functions of the clothes rack, thereby lowering the product price, increasing its price competitiveness in the market, and attracting more consumers.

[0089] Lightweight and easy to operate

[0090] The lightweight plastic positioning sleeve 8, when used in conjunction with the extension arm 3 and the fixing tube 9, reduces the overall weight of the clothes rack. This makes unfolding and folding the clothes rack easier and more convenient, reducing physical exertion and providing a better user experience.

[0091] High corrosion resistance, extending service life

[0092] Plastics have good chemical stability and do not easily react with common chemicals such as water and detergents. The positioning sleeve 8 is made of plastic, and unlike metal products, it will not rust or corrode when exposed to humid drying environments or contact with chemical cleaning products. This extends the service life of the positioning sleeve 8 and ensures the overall stable performance of the clothes rack.

[0093] Easy to mold and adaptable to diverse designs

[0094] Plastics can be easily processed into various complex shapes through injection molding, extrusion, and other molding processes. This allows for greater design flexibility in the positioning sleeve 8, enabling the design of shapes and sizes to match the structural requirements of different clothes rack models, thus meeting diverse product design needs and enhancing the product's market adaptability.

[0095] Excellent insulation properties, making it safer to use.

[0096] Plastic is a good insulating material. The positioning sleeve 8 is made of plastic, which can effectively avoid safety problems caused by contact with current in special environments, such as when using a clothes rack near a power source or in a humid environment, reducing the risk of electric shock to users and providing users with a safer and more reliable usage environment.

[0097] The port of the fixed insertion tube 9 is connected to the limiting sleeve 7, and two sets of positioning sleeves 8 are set between the two sets of limiting sleeves 7.

[0098] The advantages of the above settings are:

[0099] Enhance structural stability and improve safety in use

[0100] The limiting sleeve 7 is fitted onto the port of the fixed insertion tube 9, playing a crucial role in limiting the positioning sleeve 8 and effectively preventing it from accidentally slipping off the fixed insertion tube 9. When the clothes rack is unfolded and in use, this design ensures the stability of the connection between the long arm 3, the positioning sleeve 8, and the fixed insertion tube 9, maintaining structural stability even under significant external force or shaking. For example, when drying clothes in windy weather, it prevents the positioning sleeve 8 from detaching due to shaking, avoiding overall structural imbalance of the clothes rack and clothes falling, greatly improving safety during use.

[0101] Reduce maintenance costs and extend service life

[0102] The limiting sleeve 7 prevents potential collisions and damage caused by the positioning sleeve 8 sliding out, reducing the need for component repair or replacement due to accidental detachment. Simultaneously, preventing the positioning sleeve 8 from sliding out reduces the risk of unnecessary friction with other components, thereby reducing wear, extending the service life of each component, lowering overall maintenance costs, and improving the product's cost-effectiveness.

[0103] The limiting sleeve 7 is made of rubber.

[0104] The advantages of the above settings are:

[0105] Tight fit and enhanced positioning: Rubber has excellent flexibility and elasticity, allowing the limiting sleeve 7 to fit tightly against the port of the fixing tube 9 and the outer surface of the positioning sleeve 8. In daily use, even if the clothes rack is pulled or shaken by external forces, the limiting sleeve 7, through its own elastic deformation, always maintains effective positioning of the positioning sleeve 8, preventing the positioning sleeve 8 from slipping off the fixing tube 9 and maintaining the structural stability of the clothes rack.

[0106] Increase friction to prevent slippage: The rubber material has high surface friction. When the positioning sleeve 8 attempts to slide on the fixed insertion tube 9, the limiting sleeve 7, with its high friction, hinders the displacement of the positioning sleeve 8, keeping the positioning sleeve 8 stably between the two sets of limiting sleeves 7. This improves the reliability of the clothes rack during use and avoids structural imbalance caused by the slippage of the positioning sleeve 8.

[0107] Shock absorption and noise reduction for an optimized user experience: During the unfolding and folding of the clothes rack, the positioning sleeve 8 and the limiting sleeve 7 will come into contact and move relative to each other. The excellent shock absorption properties of rubber can absorb the vibrations generated by the collision and friction between the two, while reducing the noise generated by friction, creating a quiet and comfortable user experience, especially suitable for noise-sensitive indoor environments.

[0108] Corrosion and wear resistant, extending lifespan: Rubber has strong corrosion resistance, resisting the erosion of water, detergents, and other substances in daily use, preventing damage to the limiting sleeve 7 due to corrosion. In addition, its wear resistance also effectively reduces wear between the positioning sleeve 8 and the fixing insertion tube 9, reducing the frequency of component replacement and extending the overall service life of the clothes rack.

[0109] The examples provided in this utility model are not intended to limit the implementation methods. Those skilled in the art will recognize that various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
