[0001] This utility model relates to the field of clothes drying, and in particular to a clothes drying rod telescopic mechanism. Background Technology

[0002] The retractable drying rack assembly includes a thick rod and a thin rod, with the thin rod inserted into the thick rod and retractable; the thick rod has an end seat at its end, and the thin rod has a plug at its front end; typically the thick rod and thin rod are made of aluminum alloy, while the end seat and plug are made of plastic.

[0003] Utility model patent CN210031217U discloses a telescopic drying rack, comprising a hollow main rod and a telescopic rod. The main rod has an end cap at its end, which consists of an inner limiting tube, an outer sealing ring, and an annular connecting wall. The inner limiting tube and the outer sealing ring are connected by the annular connecting wall, and their outer walls, the inner walls of the outer sealing ring, and the rear end face of the annular connecting wall form an annular slot for tight insertion of the main rod end. The inner limiting tube extends into the main rod and has a through mounting hole inside, allowing the telescopic rod to pass through and be movably installed. A positioning tube integrally and coaxially mounted at the rear end of the telescopic rod has an outer diameter larger than the inner diameter of the mounting hole but smaller than the inner diameter of the main rod.

[0004] Utility model patent CN209568288U discloses a drying rod assembly, including two snap-fit ​​rods, each with two drying rods, and a quilt rod below each drying rod. The two ends of the drying rods are connected to the quilt rods via folding pieces. The quilt rod consists of an outer tube and an inner tube, with the inner tube and the inner wall of the outer tube connected by reinforcing ribs to enhance the strength of the quilt rod. The quilt rod and the folding pieces are connected by a connecting assembly, which includes a rivet nut, a plastic plug, and a screw head. The rivet nut is fastened to the end of the inner tube, one end of the plastic plug is fastened to the end of the outer tube, and the other end extends between the outer and inner tubes. The screw head passes through the folding piece and the plastic plug in sequence and connects to the rivet nut.

[0005] In existing technologies, when telescopic tube assemblies are in use, friction occurs between the aluminum alloy and plastic materials as the thinner rod extends or retracts within the thicker rod. This friction causes noise and wears down the materials, affecting the product's performance. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a smoother, less wear-resistant telescopic drying rod mechanism.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a drying rod telescopic mechanism, including a fixed main rod and a telescopic rod, the fixed main rod having a rod cavity in the length direction, an end seat provided at the end of the fixed main rod, a plug provided at the front end of the telescopic rod, the telescopic rod being inserted into the rod cavity of the fixed main rod, and the plug and the end seat cooperating to restrict the telescopic rod from detaching from the fixed main rod;

[0008] The bottom wall of the rod cavity of the fixed main rod is provided with a movable roller assembly. The roller assembly includes a wheel frame and multiple first rollers. The multiple first rollers are mounted side by side on the wheel frame. The bottom surface of the telescopic rod is supported on the first rollers. The upper end face of the plug of the telescopic rod is provided with a second roller. The second roller contacts the top wall of the rod cavity.

[0009] The first and second rollers work together to ensure the smooth extension and retraction of the telescopic rod within the fixed main rod.

[0010] A further technical solution of this utility model is: a third roller is provided on the lower end face of the plug of the telescopic rod, and the third roller contacts the bottom wall of the rod cavity.

[0011] A further technical solution of this utility model is: the bottom of the telescopic rod is provided with a sliding groove along the length direction, and the roller assembly is located in the sliding groove. When the telescopic rod slides relative to the fixed main rod, the roller assembly can move in the sliding groove.

[0012] A further technical solution of this utility model is: the second roller and the third roller are installed in the groove opened in the plug.

[0013] Another technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: Unlike the above solution, the end seat of the fixed main rod is provided with a fixed roller assembly, the roller assembly includes multiple parallel first rollers, and the bottom surface of the telescopic rod is supported on the first rollers.

[0014] The third technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: Unlike the above solutions, the rod cavity of the fixed main rod is provided with a roller assembly for supporting the telescopic rod. The roller assembly includes multiple first rollers arranged side by side. When the telescopic rod extends or retracts in the rod cavity of the fixed main rod, the position of the roller assembly relative to the telescopic rod will move.

[0015] Compared with existing technologies, the advantages of this invention are: by setting a movable roller assembly on the bottom wall of the rod cavity of the fixed main rod, the roller assembly includes a wheel frame and multiple parallel first rollers, while a second roller is set on the upper surface of the end cap of the telescopic rod, and the second roller contacts the top wall of the rod cavity. This technical means significantly reduces the friction between the telescopic rod and the inner wall of the fixed main rod, making the telescopic rod extend and retract more smoothly within the fixed main rod, making it easier and more convenient for users to adjust the length of the drying rack, and avoiding jamming during the extension and retraction process.

[0016] By installing a third roller on the lower end face of the plug of the telescopic rod, which contacts the bottom wall of the rod cavity, and by providing a sliding groove along the length of the bottom of the telescopic rod, the roller assembly is located within the sliding groove. When the telescopic rod slides, the roller assembly can move within the sliding groove. Multiple rollers support and limit the telescopic rod from different directions. This technology improves the stability of the telescopic rod's extension and retraction, preventing swaying and tilting, and ensuring the stability and safety of the clothes drying rack during use.

[0017] By employing a multi-roller design and the coordination of the sliding groove and roller assembly, direct friction between the telescopic rod and the inner wall of the fixed main rod is reduced. This technology effectively avoids wear on the telescopic rod and the main rod, extends the service life of the clothes drying rack telescopic mechanism, improves the reliability and durability of the clothes drying rack, reduces the frequency of maintenance and replacement, and lowers operating costs.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures. Example 1:

[0027] like Figure 1 The diagram shows the overall structure of the clothes drying rod telescopic mechanism 100 in this embodiment. It can be applied to a clothes drying machine, which includes a main unit and the clothes drying rod telescopic mechanism 100. The clothes drying rod telescopic mechanism 100 includes a fixed main rod 20 and a telescopic rod 30. The fixed main rod has a rod cavity 22 along its length. An end seat a is provided at the end of the fixed main rod 20, and a plug b is provided at the front end of the telescopic rod 30. The telescopic rod 30 is inserted into the rod cavity 22 of the fixed main rod 20. The plug b and the end seat a cooperate to prevent the telescopic rod 30 from detaching from the fixed main rod 20. This technique allows the telescopic rod 30 to be smoothly inserted into the rod cavity 22 of the fixed main rod 20, and the tight cooperation between the plug b and the end seat a effectively prevents the telescopic rod 30 from detaching from the fixed main rod 20 during telescopic movement, thus forming a stable and reliable telescopic system.

[0028] It should be noted that the telescopic drying rod mechanism 100 simplifies the connection between the telescopic rod 30 and the fixed main rod 20. At the same time, by optimizing the shape and fit of each component, the connection between the telescopic rod 30 and the fixed main rod 20 is more direct and efficient, improving the overall stability and reliability of the structure. Compared with the traditional design, it not only reduces production costs but also reduces the risk of failure caused by complex structure, making the use and maintenance of the telescopic drying rod mechanism 100 more convenient and further extending the service life of the product.

[0029] like Figures 2-4 As shown, a movable roller assembly 200 is provided on the bottom wall of the rod cavity 22 of the fixed main rod 20. The roller assembly 200 includes a wheel frame 40 and multiple first rollers 41. The multiple first rollers 41 are mounted side by side on the wheel frame 40. The bottom surface of the telescopic rod 30 is supported on the first rollers 41. A second roller 42 is provided on the upper end face of the plug b of the telescopic rod 30. The second roller 42 contacts the top wall of the rod cavity 22. The first rollers 41 and the second roller 42 work together to make the telescopic rod 30 extend and retract smoothly within the fixed main rod 20. This technology reduces the friction between the telescopic rod 30 and the inner wall of the fixed main rod 20, making the telescopic rod 30 more flexible and easy to extend and retract, effectively alleviating the jamming phenomenon during the extension and retraction process. When adjusting the length of the drying rod, the user only needs to apply a slight force, and the telescopic rod 30 can respond quickly to complete the extension and retraction action, improving the convenience and labor-saving of operation.

[0030] Meanwhile, a second roller 42 is provided on the upper end face of the plug b of the telescopic rod 30, and this roller is in close contact with the top wall of the rod cavity 22. When the telescopic rod 30 extends or retracts, the second roller 42 rolls along the top wall of the rod cavity 22, further reducing the frictional resistance between the telescopic rod 30 and the top wall of the rod cavity 22. This technical means not only makes the extension and retraction of the telescopic rod 30 more stable and smooth, but also enhances the stability and accuracy of the telescopic rod 30 during the extension and retraction process, avoiding unstable phenomena such as swaying or tilting of the telescopic rod 30, and ensuring the reliability and safety of the clothes drying rack during use.

[0031] like Figure 5 As shown, a third roller 43 is provided on the lower end face of the plug b of the telescopic rod 30. The third roller 43 contacts the bottom wall of the rod cavity 22. The bottom of the telescopic rod 30 is provided with a groove 50 along the length direction. The roller assembly 200 is located in the groove 50. When the telescopic rod 30 slides relative to the fixed main rod 20, the roller assembly 200 can move within the groove 50. The second roller 42 and the third roller 43 are installed in the wheel groove 50 opened in the plug b. When the telescopic rod 30 slides relative to the fixed main rod 20, the roller assembly 200 can not only roll freely with the movement of the telescopic rod 30, but also move flexibly within the groove 50. By converting sliding friction into rolling friction, the frictional resistance between the telescopic rod 30 and the fixed main rod 20 is reduced. This technical means has a certain protective effect on the rollers, preventing external impurities from entering and affecting the normal rotation of the rollers. It not only improves the performance of the drying rod telescopic mechanism 100, but also enhances its reliability and durability, and extends the service life of the product.

[0032] In a further preferred embodiment, a groove 50 along the length direction is designed at the bottom of the telescopic rod 30, and the roller assembly 200 is cleverly placed in the groove 50. When the telescopic rod 30 slides relative to the fixed main rod 20, the roller assembly 200 can move freely in the groove 50. The cooperative design of the groove 50 and the roller assembly 200 can effectively disperse the pressure generated by the telescopic rod 30 during the extension and retraction process. This technical means further reduces the friction between the telescopic rod 30 and the fixed main rod 20, making the extension and retraction of the telescopic rod 30 smoother. It is easier and more convenient for users to adjust the length of the drying rod. Moreover, the movement of the roller assembly 200 in the groove 50 has good guiding properties, ensuring the accuracy of the extension and retraction direction of the telescopic rod 30. Example 2:

[0033] like Figure 6As shown, the overall structure of this embodiment is consistent with that of Embodiment 1. The difference lies in that the end seat of the fixed main rod 20 is provided with a fixed roller assembly 200. The roller assembly 200 includes multiple parallel first rollers 41, and the bottom surface of the telescopic rod 30 is supported on the first rollers 41. The roller assembly 200 is fixed on the end seat, and its position is stable. It can continuously and stably provide support during the extension and retraction of the telescopic rod 30. This technical means makes the installation position of the roller assembly 200 more stable, providing a solid foundation for the extension and retraction of the telescopic rod 30.

[0034] Preferably, since the roller assembly 200 is firmly fixed to the end seat, its position remains stable throughout the extension and retraction of the telescopic rod 30, thus providing a continuous and reliable support force for the telescopic rod. This technique effectively avoids any swaying or tilting that may occur during the extension and retraction of the telescopic rod 30, ensuring the smoothness and accuracy of its movement.

[0035] Furthermore, a roller assembly 200 for supporting the telescopic rod 30 is provided inside the rod cavity 22 of the fixed main rod 20. The roller assembly 200 includes multiple first rollers 41 arranged side by side. After the telescopic rod 30 is inserted into the rod cavity 22 of the fixed main rod 20, the roller assembly 200 can fit tightly against the bottom surface of the telescopic rod 30, forming a stable support structure. When the telescopic rod 30 extends or retracts within the rod cavity 22 of the fixed main rod 20, the position of the roller assembly 200 relative to the telescopic rod 30 will move. The mobility of the roller assembly 200 can better adapt to the changes in force and position of the telescopic rod 30 during the extension and retraction process. Through the mobility of the roller assembly 200, the pressure generated by the telescopic rod 30 during the extension and retraction process is effectively distributed, reducing local wear. This technical means makes the extension and retraction of the telescopic rod 30 easier and more free, significantly improving the convenience and effortlessness of operation, and bringing a smoother user experience.

[0036] It should be noted that, according to the provided design drawings, the clothes drying rack in this technical solution includes a clothes drying rod and a quilt drying rod. Each clothes drying rod and quilt drying rod has a corresponding fixed main rod that cooperates with it, and both can be extended and retracted. The extension and retraction mechanisms between the clothes drying rod and the fixed main rod, and between the quilt drying rod and the fixed main rod, are the extension and retraction mechanisms of the drying rods described above. Users can choose to apply the extension and retraction mechanisms in any of the above embodiments according to their actual needs to meet diverse drying requirements.
