A deceleration assembly 21 is provided between the mounting disk 25, a winding assembly 26 is provided on the rotating shaft of the mounting disk 25, the winding assembly 26 includes a winding wheel 27, an inner cylinder 28 and a connecting plate 29, the inner cylinder 28 is slidably arranged on the rotating shaft of the mounting disk 25, the winding wheel 27 is arranged on the outside of the inner cylinder 28, a plurality of connecting plates 29 are connected between the winding wheel 27 and the inner cylinder 28, a steel wire rope 31 is wound around the surface of the winding wheel 27, a plurality of locking assemblies 30 are provided between the mounting disk 25 and the inner wall of the winding wheel 27, the locking assembly 30 includes a locking seat 32 and a locking cylinder 33, the locking seat 32 is arranged on the inner wall of the winding wheel 27, a slot 35 is provided in the locking seat 32, the locking cylinder 33 is arranged on the mounting disk 25, and a sliding arrangement is provided in the locking cylinder 33 An insert block 34 is provided, and a pull rod 36 is provided on one side of the insert block 34. One end of the pull rod 36 passes through the locking cylinder 33 and is connected to the insert block 34. A spring is provided between the insert block 34 and the inner wall of the locking cylinder 33; the adapter 19 is connected to the dual-axis motor 14 through a wire, and the adapter 19 can be connected to a household socket using a wire with a plug, thereby converting residential electricity into low-voltage electricity for normal operation of the dual-axis motor 14, preventing the dual-axis motor 14 from being burned due to excessive voltage input to the dual-axis motor 14; the winding assembly 26 is locked with the mounting disk 25 through the locking assembly 30. When the mounting disk 25 rotates, the winding assembly 26 will also rotate accordingly. When the wire rope 31 is worn and needs to be replaced, only the auxiliary cover plate 17 on the mounting cylinder 16 needs to be removed, and then the pull rod 36 is pulled to make the insert block 34 The locking cylinder 33 is moved into the locking cylinder, so that the plug block 34 is separated from the slot 35. At this time, the locking assembly 30 releases the lock on the winding assembly 26, and the winding assembly 26 is slid along the rotating shaft of the mounting plate 25, so that the winding assembly 26 and the wire rope 31 are taken out from the casing 2 12 together, and then the wire rope 31 wrapped around the surface of the winding wheel 27 is removed and replaced. After the replacement is completed, the winding assembly 26 and the wire rope 31 are installed back in place together. In the process of replacing the wire rope 31, it is only necessary to open the auxiliary cover 17 to expose the winding assembly 26 alone to prevent other components from being affected when disassembling the winding assembly 26. The winding assembly 26 and the wire rope 31 can be taken out of the casing 2 12 by pulling the pull rod 36. No other tools are required, and the operation is simple and convenient.

[0021] Furthermore, the reduction assembly 21 includes gear one 22, gear two 23 and gear three 24, the gear one 22 is rotatably arranged in the housing two 12, the gear one 22 is meshed with the worm 20, the gear two 23 is arranged on the rotating shaft of the gear one 22, the gear three 24 is arranged on the rotating shaft of the mounting plate 25, and the gear two 23 is meshed with the gear three 24; when the dual-axis motor 14 is started to rotate the worm 20, the gear two 23 rotates accordingly, thereby rotating the gear two 23, and then rotating the gear three 24, thereby rotating the winding assembly 26, and the wire rope 31 on the winding assembly 26 is wound or released accordingly; the gear one 22, the gear two 23 and the gear three 24 provide transmission between the rotating shaft of the worm 20 and the mounting plate 25 and reduce the rotation speed, so that the winding assembly 26 can rotate at a low speed, thereby smoothly winding or releasing the wire rope 31, and then the external clothes drying rack body connected to the wire rope 31 can move stably and smoothly during the lifting process.

[0022] Furthermore, there are three connecting plates 29 between the winding wheel 27 and the inner cylinder 28, and the three connecting plates 29 are equally divided along the circumference of the circle; the connecting plates 29 connect the winding wheel 27 and the inner cylinder 28 into a whole. At the same time, the three connecting plates 29 equally divided along the circumference of the circle have good supporting stability, thereby ensuring the stability of the overall structure of the winding assembly 26.

[0023] Furthermore, the mounting tube 16 is communicated with the interior of the casing 2 12, the winding assembly 26 is located on the inner side of the mounting tube 16, the auxiliary cover 17 is threadedly connected to the port of the mounting tube 16, an outlet box 18 is provided on one side of the mounting tube 16, an obstruction detection assembly 38 is provided in the outlet box 18, a wire hole 37 is provided on the side wall of the mounting tube 16 near the outlet box 18, one end of the wire rope 31 passes through the wire hole 37; the auxiliary cover 17 can be removed from the mounting tube 16 by twisting the auxiliary cover 17, so that the winding assembly 26 located on the inner side of the mounting tube 16 is exposed separately, and other components are not affected during disassembly.

[0024] Further, the obstruction detection assembly 38 includes a fixed box 39, which is arranged in the outlet box 18. A pressure sensor 40 is arranged at the bottom of the fixed box 39. A U-shaped plate 41 is slidably arranged on the upper side of the pressure sensor 40. A spring is arranged between the U-shaped plate 41 and the inner wall of the fixed box 39. Both ends of the U-shaped plate 41 pass through the inner wall of the fixed box 39. A rubber roller 42 is arranged between the two side walls of the U-shaped plate 41. The steel wire rope 31 passes through the wire hole 37 and then goes around the top of the rubber roller 42. The steel wire rope 31 is connected to the clothes drying rack body at its end. The steel wire rope 31 is kept taut downwardly, so that the rubber roller 42 is pressed downwardly, so that the U-shaped plate 41 is pressed against the pressure sensor 40, and the pressure sensor 40 can receive the pressure. At this time, the spring between the U-shaped plate 41 and the fixed box 39 is in a stretched state. When the clothes drying rack encounters an obstacle during the descent process, the taut steel wire rope 31 becomes loose, and the U-shaped plate 41 moves upward under the action of the spring. The pressure sensor 40 detects a decrease in pressure, thereby controlling the dual-axis motor 14 to shut down, and then controlling the clothes drying rack to stop moving, avoiding the clothes drying rack from moving further downward to prevent danger.

[0025] The working principle of the utility model is that when the wire rope 31 needs to be replaced due to long-term use, the auxiliary cover 17 is twisted to remove the auxiliary cover 17 from the mounting tube 16, so that the winding assembly 26 inside the mounting tube 16 is exposed alone, and then the pull rod 36 is pulled to make the plug block 34 move into the locking tube 33, so that the plug block 34 is separated from the slot 35. At this time, the locking assembly 30 releases the lock of the winding assembly 26, and the winding assembly 26 is slid along the rotating shaft of the mounting plate 25, so that the winding assembly 26 and the wire rope 31 are taken out from the casing 12 together, and then the wire rope 31 wrapped around the surface of the winding wheel 27 is removed and replaced. After the replacement is completed, the winding assembly 26 and the wire rope 31 are installed back to their original positions together, and the wire rope 31 is allowed to pass through the wire hole 37 and bypass the top of the top rubber roller 42, and then the end of the wire rope 31 is tied to the main body of the clothes drying rack.

[0026] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
