[0030] Combination Figures 1 to 7 The lifting electric clothes drying device of the present invention will be further described below.

[0031] A lifting electric clothes drying device is characterized by including a clothes rack 10, wherein the clothes rack 10 includes a profile 1, a main unit box 2, a lifting rod 3, and a lifting drive assembly 5.

[0032] The profile 1 is longer than the main unit 2. Guide hoisting assemblies 4 are installed at both ends of the profile 1. Each guide hoisting assembly 4 includes a hoisting plate 41 capable of being hoisted to the building's roof and guide wheels 42 disposed within the hoisting plate 41. The main unit 2 is installed at the middle of the upper surface of the profile 1 and is located between the two hoisting plates 41. The lifting drive assembly 5 includes a drive motor 52 and a rope 51. The drive motor 52 is installed in the main unit 2, and a winding wheel 53 is connected to the output shaft of the drive motor 52. The middle portion of the rope 51 is wound around the winding wheel 53, and both ends of the rope 51 pass through the main unit 2, then extend downwards around the guide wheels 42. When the drive motor rotates, it drives the winding wheel 53 to rotate, winding or unwinding the rope, thereby achieving synchronous lifting and lowering of both ends of the rope 51. The lifting rod 3 is located below the profile 1, and its two ends are connected to the two ends of the rope 51, rising and falling with the rope.

[0033] Specifically, in the entire clothes drying device, two sets of clothes racks 10 are arranged symmetrically. The clothes drying device also includes a control module, i.e., a PCB control board. The control module is electrically connected to two drive motors 52 in the two sets of clothes racks 10 to control the operation of the two drive motors 52. In this embodiment, by controlling two drive motors 52 simultaneously through one drive module, the cost of the entire clothes drying device can be reduced, and the coordinated control of the two drive motors 52 can be facilitated. That is, in actual use, the control module controls the two drive motors 52 to rotate in opposite directions at regular intervals, so that while one lifting rod 3 rises, the other lifting rod 3 falls, avoiding permanent obstruction of the clothes drying on the outer lifting rod 3 by the clothes drying on the inner lifting rod 3, so that the clothes drying on both lifting rods 3 can be effectively exposed to sunlight. On the other hand, since the two clothes racks 10 are suspended by their respective profiles 1, when one clothes rack 10 malfunctions, the corresponding clothes rack 10 can be directly disassembled without dismantling the entire clothes drying device.

[0034] The profile 1 includes a horizontal main plate 11 and vertical side plates 13. The horizontal main plate 11 has slots 111 extending along the length of the profile 1 on both sides. The lifting plate 41 has an inverted U-shaped structure, and its two side walls have locking strips 412 that can slide from the end of the profile 1 into the slots 111. The vertical side plates 13 are two in number and located on both sides of the lower surface of the horizontal main plate 11, forming a lifting rod receiving groove 12 between them. The outer surface of the vertical side plates 13 has a downward-facing light groove 131, in which a light is installed to achieve an illumination effect.

[0035] Furthermore, the two sides of the transverse main plate 11 are bent upwards and then inwards to form a slot 111. The locking strip 412 is formed by bending outwards from the bottom of the two side walls of the lifting plate 41. The slot 111 extends through both ends of the profile 1, allowing the locking strip on the lifting plate 41 to slide into the slot 111 from the end of the profile 1. The end of the transverse main plate 11 has a clearance opening 113 for the rope 51 to pass through.

[0036] The end of the clip 412 has an upwardly bent limiting strip 413 to limit the amount of sliding of the lifting plate 41 into the slot 111. The end of the profile 1 is fitted with a profile end cap 6, which is used to restrict the clip in the slot 111 and prevent the clip from accidentally falling out of the slot 111; at the same time, the profile end cap 6 is provided with a power driver for driving the light strip to emit light.

[0037] The profile end cap 6 has two sets of clamping plate groups 61 on the end facing the profile 1. Each set of clamping plate groups 61 has two parallel clamping plates 611, and the two sets of clamping plate groups 61 correspond to the two light grooves 131 respectively. In the clamping state, the two clamping plates 611 in each set of clamping plate groups 61 are respectively attached to the two inner walls of the light groove. When it is necessary to remove the profile end cap, the profile end cap can be removed from the end of the profile by manually pulling it outward.

[0038] The back of the inwardly bent portion of the horizontal motherboard 11 has an extension 112 to increase the width of the upper surface of the profile 1, which facilitates the installation and fixation of the main unit 2 on the upper surface of the profile 1.

[0039] The guide wheel 42 is mounted on the two side walls of the hoisting plate 41. A hoisting hole 411 is provided on the top surface of the hoisting plate 41. The hoisting plate 41 is hoisted to the roof of the building through the hoisting hole 411 and the corresponding hoisting rod or rope.

[0040] The lifting rod 3 includes an outer tube 32 and two inner tubes 31 that are movably fitted within the outer tube 32. The two inner tubes 31 are arranged axially along the outer tube 32, and the opposite ends of the two inner tubes 31 can be moved out of the outer tube 32 to increase the axial length of the entire lifting rod 3. The outer tube 32 is provided with a pad 8, i.e., a silicone pad or a rubber pad, to increase the friction of the hanger. This pad 8 can prevent the hangers hanging on the lifting rod 3, i.e., the outer tube 32, from slipping, thereby improving the stability of hanging hangers and drying clothes. At the same time, it can also reduce the need for hanging holes on the lifting rod 3 for positioning hangers, thus facilitating the production of the outer tube 32 in the lifting rod 3.

[0041] The top surface of the outer tube 32 has an assembly strip 321, and the two sides of the gasket 8 are bent to form an assembly groove 81 that can mate with the assembly strip 321. Specifically, the top surface of the outer tube 32 is raised upward to form a top wall protruding from the top surface of the outer tube 32, and the left and right sides of the top wall extend in opposite directions to form the assembly strip 321; the two sides of the gasket 8 are bent downward and then bent inward to form an assembly groove 81 that can be inserted into the assembly strip 321 from the end of the assembly strip 321.

[0042] The outer tube 32 is provided with connecting seats 7 at both ends. The connecting seats 7 include an outer tube end cap 72 and a rope connecting shell 71. The outer tube end cap 72 has a slot 721 for inserting the end of the outer tube 32, a claw 722 for locking the end of the outer tube 32 in a slot 111, and a central hole 723 for the inner tube 31 to pass through. The rope connecting shell 71 includes a shell 711 formed on the outer tube end cap 72 and a cover plate 712 detachably connected to the shell 711. The shell 711 has a first connecting groove 7112, and the cover plate 712 has a second connecting groove 7123. The first connecting groove 7112 and the second connecting groove 7123 cooperate to form a connecting hole for hoisting the end of the rope 51.

[0043] The slot 721 has a notch on the inner wall on the side corresponding to the center hole 723 to form a claw 722 on the inner wall. Two claws 722 are symmetrically arranged. Correspondingly, there is a slot on the side wall of the outer tube 32 near the end for the claw 722 to be engaged.

[0044] The bottom of the housing 711 is formed on the outer tube end cap 72. The housing 711 has a side opening and a top plate 7111 for the first connecting long groove 7112. One end of the first connecting long groove 7112 is a closed end, and the other end penetrates the side wall of the top plate as an open end. The cover plate 712 has an L-shaped structure and is divided into a horizontal plate 7121 and a vertical plate 7122. The vertical plate 7122 is fixed to the side opening of the housing 711 by bolts. The horizontal plate 7121 enters the housing 711. The second connecting long groove 7123 is located on the horizontal plate 7121. Similarly, one end of the second connecting long groove 7123 is a closed end, and the other end penetrates the side wall of the horizontal plate 7121 as an open end. The connecting hole is formed by the closed end of the first connecting long groove 7112 and the closed end of the second connecting long groove 7123. A hanging piece with an area larger than the connecting hole is provided at the end of the rope 51. When connecting, the hanging piece is moved into the housing 711 from the side opening, and then the cover plate 712 is installed to position the hanging piece in the housing 711. It has the characteristics of flexible and convenient assembly and disassembly.

[0045] The inner end of the inner tube 31 is connected to a limiting end cap 311 to prevent the inner end of the inner tube 31 from disengaging from the outer tube 32, and the outer end of the inner tube 31 is connected to an inner tube end cap 312. The insertion structure of the limiting end cap 311 to the end of the inner tube 31 is the same as the insertion structure of the end of the outer tube 32 to the outer tube end cap 72.
