Background Art

[0002] At present, the traditional clothes drying rod or the clothes drying rod on the clothes drying machine has multiple hanging holes fixedly arranged on the clothes drying rod, and the hanging holes are spaced at a certain distance and cannot be moved. When drying clothes, each piece of clothing is hung on the corresponding hanging hole through the clothes drying rack. When the clothes are dried, it is relatively inconvenient to collect the clothes.

[0003] In order to solve the above problems, a clothes drying rod assembly with announcement number CN208586438U includes a clothes drying rod, a connecting rope and a plurality of hanging hole assemblies, each hanging hole assembly is distributed on the track along the length direction of the track, and adjacent hanging hole assemblies are connected by connecting ropes. The above movable plurality of hanging hole assemblies can flexibly hang clothes, which not only meets the need for convenient collection of clothes, but also allows for dispersed drying.

[0004] The clothes-drying assembly and clothes-drying system of CN212834640U can slide the clothes-drying assembly as required to make adjacent sliding parts to be linked and unfolded or brought together.

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

"First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present invention.

[0044] An electric clothes drying rack capable of automatically adjusting the distance between clothes, the embodiment of the invention is as follows Figures 1 to 7 As shown, it includes a main machine 1 and a liftable drying rod 2, wherein the end of the main machine 1 is provided with an upper coupling 3 driven by a motor 8; the head end of the drying rod 2 is provided with a lower coupling 4 and a main gear 5, and the main gear 5 is coaxially arranged on the lower side of the lower coupling 4; the tail of the drying rod 2 is provided with a passive gear; the lower end surface of the upper coupling 3 is provided with a first tooth portion 12, and the upper end surface of the lower coupling 4 is provided with a second tooth portion 13.

[0045] When the clothes-drying rod 2 rises to the upper limit position, the first tooth portion 12 of the upper coupling 3 and the second tooth portion 13 of the lower coupling 4 engage, the motor 8 drives the upper and lower couplings 4 and drives the belt 10 to reciprocate, which can drive the last hanging ring 9 to reciprocate in the linear slide 7, and then drive all the hanging rings 9 on the clothes-drying rod 2 to disperse and gather together.

[0046] In the present invention, no power device is installed in the drying rod 2. The present invention concentrates the motor 8 on the main machine 1, and sets the upper coupling 3, and then sets the lower coupling 4 on the drying rod 2 accordingly. When the upper coupling 3 and the lower coupling 4 are engaged, the motor 8 drives the lower coupling 4 on the drying rod 2 to rotate, and drives the main gear 5 to rotate through the lower coupling 4. When the drying rod 2 leaves the upper limit position, the lower coupling 4 loses the force and is in a free state, and the lower gear can rotate freely. In other words, after the drying rod 2 is lowered, the user can manually pull the hanging ring 9 on the drying rod 2, so as to facilitate the use of the user and adapt to the user's usage habits.

[0047] The drying rod 2 is provided with a linear slide 7 extending along the length of the drying rod 2 and an annular groove surrounding the linear slide 7, and a plurality of hanging rings 9 are provided in the linear slide 7; a belt 10 is provided in the annular groove, and the belt 10 is connected to the main gear 5 and the passive gear; the first hanging ring 9 is fixed in the slide of the drying rod 2; adjacent hanging rings 9 are connected by soft wires 11, and finally the hanging ring 9 is connected to the belt 10.

[0048] In the present invention, a linear chute 7 extending along the length of the air-drying rod 2 is planned for installing a plurality of hanging rings 9, and an annular groove surrounding the linear chute 7 is planned for installing a belt 10, and the main gear 5 rotates to drive the belt 10 and the passive gear to rotate. The movement of the belt 10 drives the hanging ring 9 to be unfolded and retracted. Specifically, the present invention can be arranged that when the air-drying rod 2 is lowered (generally when the user needs to dry clothes or collect clothes), the motor 8 works to collect the plurality of hanging rings 9 to the head end of the air-drying rod 2, and the user only needs to stand in place to hang all the clothes that need to be dried on the plurality of hanging rings 9, or collect the clothes that have been dried. After the clothes-drying rod is set to rise to the upper limit, the motor 8 works, and the plurality of hanging rings 9 are pulled mutually and dispersed on the air-drying rod 2, and the clothes hung on the hanging rings 9 are evenly dispersed, so that ventilation is realized to accelerate drying.

[0049] The motor 8 is driven by the upper coupling 3 through the gear set 21. The motor 8 is driven by the upper coupling 3 through the gear set 21, and the speed of the motor 8 can be adjusted by multiples according to actual needs and then output to the upper coupling 3. The setting of the gear set 21 provides a more flexible solution for the selection of the motor 8. The gear set 21 can increase the output torque, meet different load requirements, and improve the carrying capacity of the system.

[0050] Embodiment 2, as Figures 1 to 7 As shown, the lower coupling 4 is arranged at the bottom of the cylindrical part 22. When the upper coupling 3 is docked with the lower coupling 4, the peripheral wall of the upper coupling 3 enters into the concave cavity of the cylindrical part 22. The concave cavity design of the cylindrical part 22 can effectively guide the upper coupling 3 and the lower coupling 4 to dock accurately, ensure the alignment of the axes of the upper and lower couplings, and avoid eccentricity and runout. And the peripheral wall of the upper coupling 3 enters into the concave cavity of the cylindrical part 22, which provides radial support, increases the rigidity and stability of the connection, and reduces vibration during operation.

[0051] There is a gap between the outer periphery of the lower coupling 4 and the inner wall of the cylindrical portion 22, and the peripheral wall of the upper coupling 3 matches the gap. The top surface of the cylindrical portion 22 is a conical surface 23 whose outer periphery is higher than the inner periphery, and the outer ring of the peripheral wall of the upper coupling 3 is adapted to the top surface of the cylindrical portion 22. In the scheme of the present invention, the top surface of the cylindrical portion 22 is designed as a conical surface 23, which plays a positioning and guiding role. In conjunction with the peripheral wall of the upper coupling 3 that is adapted, the upper coupling 3 can be automatically aligned, and the upper coupling 3 and the lower coupling 4 are aligned, thereby improving the reliability and efficiency of docking. When the upper coupling 3 is docked with the lower coupling 4, the peripheral wall of the upper coupling 3 is sleeved on the outer periphery of the lower gear portion, and the cylindrical portion 22 is sleeved on the outer periphery of the upper coupling 3.

[0052] The first tooth portion 12 has the same structure as the second tooth portion 13. The second tooth portion 13 includes a plurality of tooth surfaces 24, which are surrounded to form a circular ring structure. The tooth surface 24 is in the shape of a fan set at an angle. The tooth surface 24 includes a convex side 24a and a connecting side 24b. The convex side 24a of the tooth surface 24 is set higher than the connecting side 24b. The convex side 24a of the tooth surface 24 is transitioned with an arc angle 24c between the convex side 24a of the tooth surface 24 and the outer peripheral surface. After the upper and lower couplings are disengaged, the lower coupling 4 is in a free state and will rotate under external force. Therefore, when the lower coupling 4 rises and meshes with the upper coupling 3 for the next time, the first tooth portion 12 and the second tooth portion 13 may be misaligned. At this time, continuing to force the rise will cause the first tooth portion 12 and the second tooth portion 13 to collapse. In response to this problem, the present invention adopts a tooth row method. That is, the tooth surface 24 is in the shape of a fan set at an angle, and the convex side 24a of the tooth surface 24 is transitioned with an arc angle 24c between the convex side 24a of the tooth surface 24 and the outer peripheral surface. When the first tooth portion 12 and the second tooth portion 13 are misaligned and meshed, the arc angle 24c will press against the inclined fan surface. Under the action of pressure, the arc angle 24c slides against the fan surface until the fan surface of the first tooth portion 12 fits with the fan surface of the second tooth portion 13.

[0053] A compression spring 25 is provided between the upper coupling and the main machine 1, and the compression spring 25 applies a downward thrust to the upper coupling 3; the compression spring 25 drives the upper coupling 3 to extend downward for a distance, and the lower coupling 4 rises to contact the upper coupling 3 and drives the upper coupling 3 to rise. The present invention increases the elastic force of the upper coupling 3 when it is engaged by providing the compression spring 25. When the upper and lower couplings just come into contact, it can play a buffering role, making it a soft connection and reducing the wear between the gears. At the highest point of the rise, the matching clearance between the upper and lower couplings is eliminated.

[0054] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0055] Embodiment three, as Figures 1 to 11As shown, the annular groove includes an arc groove 14 located at both ends of the drying rod 2 and a linear belt groove 15 located outside the linear slide 7; a partition 16 is provided between the linear belt groove 15 and the linear slide 7, and a through groove 17 is provided in the middle of the partition 16; the belt 10 is connected to the last hanging ring 9 through a transverse connecting portion 18, and when the belt 10 slides, the transverse connecting portion 18 can slide along the through groove 17.

[0056] The present invention realizes the installation and limiting of the belt 10 by setting an annular groove, ensuring that the belt 10 can move along a predetermined trajectory. The installation and limiting of the hanging ring 9 are realized by setting a linear slide 7, ensuring that the hanging ring 9 can move along the length direction of the clothes-drying rod 2 to avoid shaking. And the linear belt groove 15 and the linear slide 7 are separated by a partition 16 to avoid the mutual influence between the belt 10 and the hanging ring 9. In the present invention, the belt 10 only needs to drive the last hanging ring 9 to slide to realize the expansion or folding of all the hanging rings 9. Therefore, a groove 17 is provided on the partition 16, and a transverse connecting part 18 is provided to connect the belt 10 with the last hanging ring 9 to realize the driving of multiple hanging rings 9.

[0057] The inner side of the belt 10 is regularly arranged with gear teeth 26, one end of the transverse connection part 18 is connected to the last hanging ring 9, and the other end of the transverse connection part 18 is connected to the bite block 27, which is installed on the belt 10, and the bite block 27 is engaged with the gear teeth 26 on the belt 10. The moving belt 10 drives the last hanging ring 9 to move along the linear slide 7 through the transverse connection part 18. When the last hanging ring 9 is forced to move toward the tail of the drying rod 2, the adjacent hanging rings 9 are pulled one by one by the soft wire 11, and multiple hanging rings 9 are unfolded; when the last hanging ring 9 is forced to move toward the head end of the drying rod 2, the last hanging ring 9 moves and contacts with the adjacent hanging rings 9 to push the hanging rings 9 to be recovered one by one.

[0058] The cross section of the linear belt groove 15 is a rectangular frame structure, the belt 10 is installed in the linear belt groove 15, and the through groove 17 is provided on the adjacent side of the linear belt groove 15 and the linear slide groove 7. The linear belt groove 15 stores the belt 10 well, preventing the belt 10 from being exposed to the outside and causing the user to touch it by mistake, and also preventing dust and foreign matter in the external environment from entering the belt 10, causing abnormal noise or blockage when the belt 10 moves.

[0059] The cross section of the linear slide 7 is a rectangular frame structure, and a slot is provided on the top surface of the linear slide 7 for the upper end surface of the slider 20 to pass through, and the moving wheel 19 is located in the linear slide 7. Similarly, the linear slide 7 structure also stores the lower ends of the moving wheel 19 and the slider 20 to avoid exposure to accidental touching by the user and to prevent dust and foreign matter from entering.

[0060] The hanging ring 9 is a slider 20 equipped with a moving wheel 19. The upper end surface of the slider 20 is higher than the upper surface of the clothes-drying rod 2, and the upper end surface of the slider 20 is a concave arc surface. When the clothes-drying rod 2 is raised to the upper limit, there is a gap between the hanging ring 9 and the main unit 1, which can accommodate the hanging of the hanger. Specifically, the upper end surface of the slider 20 can be a wave-shaped structure, including crests and troughs. When the clothes hanger is hung on the upper end surface of the slider 20, the clothes hanger will naturally fall to the trough and be limited by the crests on both sides.

[0061] The present invention is provided with a moving wheel 19 on the hanging ring 9, and the moving wheel 19 can effectively reduce the friction resistance when the hanging ring 9 moves, so that the hanging ring 9 moves smoothly. Whether the user pushes and pulls manually or is driven by the motor 8, the hanging ring 9 can be easily driven to move.

[0062] The other contents of the third embodiment are the same as those of the first embodiment or the second embodiment.
