[0044] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0045] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0046] like Figures 1 to 4 As shown, a single-pole clothes drying machine 100, designed to increase the amount of clothes drying, comprises a main unit 10 and a drying rod 20. The rod 20 is connected to the main unit 10 at each end via a steel cable 30. The main unit 10 is the core component of the clothes drying machine, responsible for supporting and driving the entire system. It typically incorporates a built-in motor and control system to enable the automatic raising and lowering of the clothes drying machine. The drying rod 20 serves as the primary platform for drying clothes. The rod 20 is connected to the main unit 10 at both ends via steel cables 30. This technology allows the rod 20 to be raised and lowered smoothly under the control of the main unit 10, making it convenient for users to hang and remove clothes.

[0047] Preferably, the clothes drying rod 20 is made of high-strength material to ensure stability and durability when carrying a large amount of clothes.

[0048] The clothes drying rod 20 comprises a housing 21 with an inner cavity h. This cavity h is a key component of the clothes drying rod 20, providing the necessary space for the clothes drying machine's functionality. A rack 40, aligned with the direction of the clothes drying rod 20, is located within this cavity h. This allows the clothes drying rod 20 to perform complex mechanical movements, enhancing the practicality and flexibility of the clothes drying machine. Rack 40 is equipped with teeth 41 on both sides, which are key components for precise control and power transmission.

[0049] The rack 40 and the tooth portion 41 are designed with reference to the geometric parameters of a standard basic rack tooth profile, ensuring meshing accuracy and transmission efficiency between the rack and the gear. The configuration of the tooth portion 41 of the rack 40 also takes into account the basic rack parameters recommended for different usage scenarios to accommodate different loads and operating conditions. For example, the rack tooth profile can be selected as a straight line with the same pressure angle at each point, which helps reduce friction, extend the service life of the machine, and basically does not cause heat generation or component wear. Alternatively, the rack tooth direction can be a circular arc tooth line. During installation, it can be rotated along the tooth line by a small angle without affecting its meshing transmission, and the gear pair installation parallelism error is highly adaptable. Manufacturers can make this selection based on actual assembly requirements.

[0050] In addition, openings k communicating with the inner cavity h are provided on both sides of the shell 21. This technical means not only optimizes the compactness of the structure, but also improves the space utilization of the clothes drying machine. A plurality of support rods 50 are axially connected to both sides of the shell 21. The plurality of support rods 50 are arranged in the openings k on the side of the shell 21 along the length direction. The openings k allow the axial ends of the support rods 50 to pass through smoothly, so that the support rods can be arranged on the side of the shell 21 along the length direction. This layout allows the clothes drying machine to provide more clothes drying positions while maintaining a compact structure. The axial ends of the support rods 50 are provided with fan-shaped teeth 51, and the teeth 41 engage with the fan-shaped teeth 51. The engagement of the fan-shaped teeth 51 with the rack 40 provides a precise control mechanism, so that the support rods 50 can stably switch between the storage and deployment positions, ensuring a smooth and safe clothes drying process.

[0051] By arranging a plurality of support rods 50 on both sides of the housing 21, the clothes drying machine can provide more clothes drying positions within a limited space, thereby optimizing the utilization efficiency of the space.

[0052] Furthermore, if Figure 7 As shown, an adjustment handle 60 is provided on the outer side of the housing 21 and is threadedly connected to the rack 40. Rotating the adjustment handle 60 drives the rack 40 to move forward and backward a certain distance within the inner cavity h of the housing 21. The teeth 41 then engage the sector teeth 51, allowing the support rod 50 to rotate between a first, stowed position and a second, extended position.

[0053] The adjustment handle 60 on the outside end of the housing 21 is a key user-interaction component. It is directly connected to the rack 40 via a threaded connection, allowing users to control the functions of the clothes dryer with a simple rotation. The design of the adjustment handle 60 takes user convenience into consideration. Its position and shape allow users to easily grasp and apply force to achieve precise control of the rack 40.

[0054] In addition, the threaded connection between the adjustment handle 60 and the rack 40 ensures that when the handle is turned, the rack can move smoothly and accurately back and forth in the inner cavity h. This connection not only provides good mechanical advantages, but also ensures smooth and reliable operation.

[0055] Finally, by rotating the adjustment handle 60 , the user can easily adjust the position of the rack 40 , thereby controlling the deployment and storage of the support rod 50 .

[0056] It should be noted that the cooperation between the rack 40 and the sector teeth 51 provides a transmission method with high efficiency and self-locking properties, thereby ensuring a stable transition of the support rod 50 between the stowed and deployed positions.

[0057] When the support rod 50 is in the first position of storage, Figure 5As shown, the technical means is parallel to the rack 40 and located in the opening k of the side of the shell 21, which makes the support rod 50 compactly stored when not in use, reduces space occupation, makes the clothes drying machine more tidy when not in use, and is convenient for storage.

[0058] As shown in Figure 7 and Figure 8 When the support rod 50 is expanded to the second position, it leaves the opening k and forms an angle with the shell 21, which allows the support rod 50 to effectively support the clothes and provide a stable drying platform. This allows the clothes to get better ventilation and light when drying, speeding up the drying process of the clothes.

[0059] The angle formed by the support rod 50 and the shell 21 can be adjusted according to the needs of the user to adapt to different lengths and types of clothes. This flexibility allows the clothes drying machine to meet a variety of drying needs, whether it is long or short clothes, a suitable drying angle can be found. Moreover, this angle not only provides the function of drying, but also enhances the stability of the structure.

[0060] Preferably, the maximum included angle between the support rod 50 and the rack 40 is 90 degrees when the support rod 50 is expanded to the second position. The 90-degree included angle allows the support rod 50 to maximize the use of space when expanded, providing the maximum drying area. In addition, this vertical layout provides better mechanical support, enhancing the stability and load-bearing capacity of the entire clothes drying structure.

[0061] Preferably, the shell 21 includes a narrow part a at the upper part and a wide part b at the lower part, and the rack 40 and the support rod 50 are located at the wide part b. The design of the narrow part a takes into account the compactness of the space, suitable for placing components that do not occupy too much space, while the wide part b provides a suitable position for the rack 40 and the support rod 50 which require more space. This design of upper and lower parts makes the structure of the shell 21 more reasonable, facilitating the layout and maintenance of components.

[0062] By arranging the rack 40 and the support rod 50 in the wide part b, the lower space of the shell 21 can be maximized, while the upper narrow part a remains light, which helps to improve the space utilization efficiency and overall balance of the clothes drying machine.

[0063] More specifically, the end of the shell 21 in this embodiment is provided with an end plate c, and the inner side and the outer side of the end plate c are respectively provided with nuts d. The adjusting handle 60 is connected with a screw rod 61, and the screw rod 61 passes through the two nuts d respectively and is connected with the rack 40. The end plate c plays a role of fixing and supporting, and the inner side and the outer side thereof are respectively provided with nuts d, thereby enhancing the stability of the entire structure. The nuts d here play a role of locking and fixing the screw rod 61, ensuring that the screw rod does not shift or loosen during adjustment, thereby ensuring the accuracy and reliability of the adjustment.

[0064] The screw rod 61 connected with the adjusting handle 60 is connected with the rack 40 through two nuts d, and this technical means allows precise control of the rack 40 by rotating the adjusting handle 60. This connection of the screw rod 61 through the nuts not only provides a stable transmission path, but also allows fine adjustment under different loads to adapt to different use requirements.

[0065] Preferably, when the support rod 50 is located in the opening k, the outer wall of the support rod 50 does not exceed the outer wall of the shell 21. On the one hand, it makes the clothes drying machine more smooth and coordinated in appearance, without protruding parts, providing a better visual experience, especially suitable for modern home environment, blending with the home decoration style. On the other hand, it helps to enhance the stability of the overall structure. Thus it can ensure that the support rod 50 fits closely with the shell in the storage state, reducing the shaking, thereby improving the stability and durability of the clothes drying machine. In addition, when the outer wall of the support rod 50 is flush with the outer wall of the shell 21, the appearance of the entire clothes drying machine is more neat and beautiful.

[0066] Further, the rack 40 is provided with limit strips 70 distributed at intervals on both sides, and the adjacent limit strips 70 form an empty area f accommodating the sector teeth 51. The inner end of the support rod 50 is provided with a limit protrusion 52, which is located on the side of the sector teeth 51. The limit protrusion 52 cooperates with the inner end of the limit strip 70 to limit the maximum amplitude of the outward rotation of the sector teeth 51.

[0067] The cooperation of the limit strip 70 and the empty area f ensures the flexibility and accuracy of the installation of the sector teeth 51 during rotation. In addition, through the cooperation of the limit protrusion 52 and the inner end of the limit strip 70, the maximum amplitude of the outward rotation of the sector teeth 51 is effectively limited.

[0068] In addition, as shown in Figure 6 、 Figure 7 The inner end of the support rod 50 is provided with a shaft connecting hole g0, and the sector teeth 51 are arranged around the shaft connecting hole g0. The empty area f is provided with a shaft connecting column g. The shaft connecting hole g0 and the shaft connecting column g are rotationally connected. The rotationally connected shaft connecting hole g0 and shaft connecting column g provide a stable and flexible connection method. This makes the support rod 50 rotate smoothly during unfolding and storage, reducing wear caused by friction.
