[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0033] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] See also Figures 1 to 7 As shown, the utility model provides a clothes drying machine 200, including a traction rope 110, a main body 120, a clothes drying rod 130 and a rope reel 140, wherein the main body 120 is used to be installed on a mounting base. The rope reel 140 is arranged inside the main body 120, and the rope reel 140 is connected to the clothes drying rod 130 through the traction rope 110, and the rope reel 140 drives the clothes drying rod 130 to move up and down relative to the main body 120 through the traction rope 110.

[0035] In order to further adjust the height of both ends of the clothes drying rod 130 to keep it horizontal, the clothes drying machine 200 is further provided with a connecting structure 100, which is used to fine-tune the height of both ends of the clothes drying rod 130. The connecting structure 100 is fixedly connected to the clothes drying rod 130, and one end of the traction rope 110 is connected to the rope reel 140, and the other end is connected to the connecting structure 100. That is, the connecting structure 100 is used to connect the clothes drying rod 130 and the traction rope 110 of the clothes drying machine 200.

[0036] The connection structure 100 includes an adjustment member 1 and a connection member 2, wherein the connection member 2 includes a first portion 23 and a second portion 24, wherein the first portion 23 and the second portion 24 are fixedly connected to both sides of the clothes drying rod 130, and the first portion 23 and the second portion 24 are both provided with a recessed portion, and the recessed portion is used to accommodate the adjustment member 1 and a portion of the traction rope 110. The connection member 2 includes a first connection portion 21 for fixedly connecting to the clothes drying rod 130, and a second connection portion 22 for connecting to the traction rope 110. Specifically, the first connection portion 21 is a fixing hole provided on the connection member 2, and a fastener passes through the fixing hole to fix the connection member 2 to the clothes drying rod 130.

[0037] Furthermore, the traction rope 110 includes a limiting head 1101, a limiting protrusion 1103 and a main rope portion 1102 connected to the limiting protrusion 1103. The limiting head 1101 and the limiting protrusion 1103 are located at the ends of the traction rope 110 and are arranged at intervals. The limiting protrusion 1103 protrudes outward from the main rope portion 1102.

[0038] The second connecting part 22 includes a first cavity 221, a second cavity 222, and a connecting passage 223 disposed between the first cavity 221 and the second cavity 222. Specifically, the first part 23 and the second part 24 are fixedly connected to both sides of the clothes drying rod 130, that is, when the first part 23 and the second part 24 are spliced, the recessed part of the first part 23 and the recessed part of the second part 24 are jointly formed to form the first cavity 221, the second cavity 222 and the connecting passage 223. In other words, the first cavity 221 and the connecting passage 223 are closed structures; in addition, the second cavity 222 is entered through the adjusting member 1 to close the opening of the second cavity 222. The closed structure can prevent external dust, debris or moisture from entering the cavity and the passage, thereby keeping the internal structure clean and dry. The closed first cavity 221 is configured to accommodate and limit the limit head 1101, which can effectively prevent the limit head 1101 from detaching from the first cavity 221, thereby ensuring a firm connection between the traction rope 110 and the connecting structure 100, and avoiding the risk of accidental falling off of the clothesline 130 due to the detachment of the traction rope 110.

[0039] Specifically, the first cavity 221 and the second cavity 222 are connected through a connecting channel 223, the limiting protrusion 1103 is arranged at intervals with the limiting head 1101 and connected through the main rope portion 1102, the connecting channel 223 is configured to allow the main rope portion 1102 to pass through, and the cross-sectional area of ​​the connecting channel 223 is smaller than the cross-sectional area of ​​the limiting head 1101, which can limit the limiting head 1101. The limiting head 1101 is arranged in the first cavity 221 and is limited by the connecting channel 223, so that the limiting head 1101 is always limited in the first cavity 221, even if the adjusting member 1 is separated from the connecting structure 100 during the adjustment process, the traction rope 110 will not be separated from the connecting structure 100, thereby avoiding safety hazards such as the clothes drying rod 130 falling, and improving the overall safety of the clothes drying machine 200. At the same time, the limiting protrusion 1103 and the limiting head 1101 are connected through the main rope part 1102 to form a complete connection structure 100, which effectively disperses the force and avoids excessive force at a single point, thereby improving the bearing capacity of the entire structure.

[0040] The limiting head 1101 is located at the end of the traction rope 110, and a connecting rope portion 1104 is connected between the limiting protrusion 1103 and the limiting head 1101, and the length of the connecting rope portion 1104 is greater than the length of the connecting channel 223. The connecting rope portion 1104 can give the traction rope 110 a certain activity space, and cooperate with the adjusting member 1 to adjust the height of the traction rope 110.

[0041] Further, the adjusting member 1 is at least partially accommodated in the second cavity 222 and is movably connected to the second cavity 222. The adjusting member 1 has a hollow accommodating cavity 132. The limiting protrusion 1103 is disposed in the accommodating cavity 132 and abuts against the cavity wall of the accommodating cavity 132. The adjusting member 1 can be displaced in the vertical direction relative to the second cavity 222 to displace the clothes drying rod 130 in the vertical direction. In this embodiment, the external force drives the adjusting member 1 to move downward in the vertical direction. The limiting protrusion 1103 abuts against the cavity wall of the accommodating cavity 132 under the action of gravity. The adjusting member 1 and the traction rope 110 are limited and cooperated and move synchronously. The connecting rope portion 1104 is squeezed and curled, and the overall length of the hoisted traction rope 110 is shortened, so that the height of the clothes drying rod 130 at one end of the adjusting member 1 rises, so as to adjust the clothes drying rod 130 until both ends are in a horizontal state.

[0042] Specifically, the adjusting member 1 includes a head 11 and a fixing portion 12. The diameter of the head 11 is larger than the diameter of the second cavity 222, and the head 11 cannot completely enter the second cavity 222, which facilitates the installation and removal of the adjusting member 1. The fixing portion 12 is at least partially accommodated in the second cavity 222, the accommodating cavity 132 is located inside the fixing portion 12, and the outside of the fixing portion 12 is threadedly connected to the second cavity 222, so that the adjusting member 1 can be easily screwed into or out of the second cavity 222, thereby simplifying the installation and removal process. The user can easily complete the installation and removal of the adjusting member 1 without using special tools or complicated operations.

[0043] The adjusting member 1 also includes a through hole 13 that penetrates in the vertical direction, and the through hole 13 includes a first clearance hole 131 and a receiving cavity 132 that are arranged up and down and communicate with each other. The diameter of the first clearance hole 131 is smaller than the diameter of the receiving cavity 132, and the first clearance hole 131 is configured to allow only the main rope portion 1102 to pass through, and to limit the limiting protrusion 1103. The receiving cavity 132 is configured to accommodate the limiting protrusion 1103. During the adjustment of the adjusting member 1, the receiving cavity 132 and the limiting protrusion 1103 remain relatively still, so that the main rope portion 1102 and the adjusting member 1 move synchronously to achieve the height adjustment of the clothes drying rod 130.

[0044] In this embodiment, the adjusting member 1 is a screw. When one end of the clothesline 130 is low, the adjusting member 1 at the low end is screwed into the second cavity 222, and the limiting protrusion 1103 moves downward accordingly, and remains relatively still with the accommodating cavity 132, compressing the accommodating space of the connecting rope portion 1104 in the second connecting portion 22, causing part of the connecting rope portion 1104 to bend or curl up, and reducing the overall length of the main rope portion 1102 in the vertical direction, thereby increasing the height of the connecting structure 100, and the height of the clothesline 130 fixedly connected to the connecting structure 100 increases accordingly, and the adjusting member 1 stops rotating when it rises to the level of both ends of the clothesline 130. When one end of the clothesline 130 is too high, the adjusting member 1 at the high and low ends is rotated out of the second cavity 222, and the limiting protrusion 1103 moves upward accordingly and remains relatively still with the accommodating cavity 132. The accommodating space of the connecting rope portion 1104 in the second connecting portion 22 is increased, and the bent or curled connecting rope portion 1104 is straightened again, and the overall length of the main rope portion 1102 in the vertical direction increases, so that the height of the connecting structure 100 in the vertical direction is reduced, and the height of the clothesline 130 fixedly connected to the connecting structure 100 is reduced accordingly, and the adjusting member 1 stops rotating when it drops to the horizontal position at both ends of the clothesline 130.

[0045] In order to facilitate the installation and removal of the traction rope 110, an opening 14 is also provided on the side of the adjusting member 1, and the opening 14 is connected to the accommodating chamber 132. When installing, it is only necessary to align the opening 14 with the main rope portion 1102 and push it in with a little force, so that the main rope portion 1102 can smoothly pass through the yield hole 131 and enter the accommodating chamber 132. When the limiting protrusion 1103 abuts against the accommodating chamber 132, the installation is completed. The setting of the opening 14 allows the main rope portion 1102 of the traction rope 110 to easily enter the through hole 13 through the opening 14, without the need for complicated operations or tools, thereby simplifying the installation process and improving the installation efficiency. Similarly, when it is necessary to remove the adjusting member 1, after the adjusting member 1 is rotated out of the second cavity 222, the main rope portion 1102 can be easily separated from the adjusting member 1 through the opening 14, and then the adjusting member 1 can be taken out, which greatly improves the convenience of disassembly.

[0046] Preferably, the diameter of the opening 14 is smaller than the diameter of the limiting protrusion 1103, preventing the limiting protrusion 1103 from detaching from the opening 14, ensuring that the connection between the traction rope 110 and the adjusting member 1 remains stable during normal use and is not easy to loosen or fall off, reducing the safety hazards caused by loose connection, thereby improving the safety of user use.

[0047] Preferably, the first cavity 221 has a first extension direction. In this embodiment, the first extension direction is a horizontal direction. In the first extension direction, the length of the stopper 1101 is less than the length of the first cavity 221, so that the stopper 1101 has a certain range of movement in the first cavity 221. This design increases the flexibility of the clothes drying rod 130 when adjusting the height. Even if there is a certain error during the installation process, it will not cause much impact on the normal use of the clothes drying rod 130, that is, it reduces the requirements for installation accuracy and improves the user experience.

[0048] Further, the second cavity 222 has a second extension direction. In this embodiment, the second extension direction is a vertical direction. There is an angle between the first extension direction and the second extension direction, and the angle is an acute angle or a right angle. Such a configuration can effectively utilize space and avoid overlapping or occupying too much space in the same direction; the entire structure is more compact, which is particularly suitable for application scenarios with limited space. There is an angle between the first extension direction and the second extension direction. When the angle is an acute angle, the active friction of the limit head 1101 is increased, so that the limit head 1101 is not easy to shift, thereby improving the protection and stability of the entire connection structure 100. There is an angle between the first extension direction and the second extension direction. When the angle is a right angle, it is convenient for the traction rope 110 to move, and more accommodation space is provided, which helps to reduce the excessive extrusion of the traction rope 110 during the movement and ensures the normal service life of the traction rope 110.

[0049] In summary, the adjusting member 1 of the utility model and the traction rope 110 adopt a limited fit, and the adjusting member 1 is moved downward, so that the height of the clothes drying rod 130 at one end of the adjusting member 1 rises, so as to adjust the clothes drying rod 130 to a horizontal state at both ends. By limiting the limit head 1101 in the first cavity 221, even if the adjusting member 1 accidentally detaches from the connecting structure 100 during the adjustment process, the connecting structure 100 still remains firmly connected to the traction rope 110. Since the clothes drying rod 130 is fixedly connected to the connecting structure 100, the safety hazard of the clothes drying rod 130 falling is avoided, and the safety performance of the clothes drying machine 200 is improved. Compared with the prior art, the clothes drying machine 200 of the utility model is simpler and more convenient in the operation of adjusting the two ends of the clothes drying rod 130 to be horizontal, and at the same time, the risk of the clothes drying rod 130 falling is avoided through structural design, providing users with more reliable safety protection during the adjustment process.

[0050] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
