[0002] An electric drying rack is an innovative product that combines modern technology with the needs of home life. It uses electric drive to realize the automatic lifting of the drying rack, greatly improving the convenience and efficiency of drying clothes. The wire winding mechanism on the electric drying rack is its core structure. The wire winding mechanism uses an intelligent controller to control the servo motor, so as to be able to automatically wind and unwind the steel wire rope on the drying rack, and then realize the automatic lifting of the drying rack.
[0003] As a commonly used device in the family, the electric drying rack has a high usage frequency. Long-term use will cause the steel wire rope on the wire winding mechanism to gradually become loose due to long-term stretching and vibration. The loose steel wire rope is prone to breakage due to the winding tension during the winding process. When the steel wire rope breaks, since the servo motor of the wire winding mechanism continues to work, the broken steel wire rope will continue to wind, which not only causes inconvenience to subsequent maintenance, but also may cause further damage or safety hazards due to the winding and knotting of the steel wire rope. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a wire winding mechanism for an electric drying rack and an electric drying rack, which are proposed to solve the problem that the steel wire rope of the existing wire winding mechanism of the electric drying rack continues to wind after breaking, resulting in inconvenient maintenance.
[0005] To achieve the above purpose, the utility model adopts the following technology: a wire winding mechanism for an electric drying rack and an electric drying rack, including a mounting top plate. A machine box is arranged in the middle of the bottom of the mounting top plate. A wire winding and unwinding assembly is arranged on the mounting top plate at a position on one side of the machine box. A resistance strain gauge is arranged on the mounting top plate through a mounting plate, and the steel wire rope on the wire winding and unwinding assembly is turned by a guide wheel connected to the resistance strain gauge. The resistance strain gauge is electrically connected to a controller in the machine box.
[0006] As a further description of the above technical solution: a wire clamping assembly is arranged on the mounting top plate at the position of the moving path of the steel wire rope. The wire clamping assembly includes a mounting frame fixed to the bottom of the mounting top plate. A cushion block is arranged on the mounting frame, and an elastic member is arranged at the bottom of the mounting frame and is matched with the cushion block.
[0007] As a further description of the above technical solution: the elastic member includes a connecting shaft penetrating through the bottom of the mounting frame. A top head is arranged on the connecting shaft below the cushion block, and a spring is sleeved on the connecting shaft at a position between the top head and the mounting frame.
[0008] As a further description of the above technical solution: a first threaded end is provided at the top of the connecting shaft, and a connecting screw hole matching the first threaded end is provided at the bottom of the top head. A locking nut is provided at the bottom of the connecting shaft through a second threaded end.
[0009] As a further description of the above technical solution: the wire winding and unwinding assembly includes a fixing frame fixed on the installation top plate. A wire winding cylinder is provided on the fixing frame. A first gear is fixedly connected to the bottom of the wire winding cylinder. A second gear meshing with the first gear is provided on the fixing frame through a servo motor.
[0010] As a further description of the above technical solution: a guiding shaft is provided on the fixing frame through a fixing rod. The steel wire rope horizontally extends to the guiding wheel after being guided by the guiding shaft.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0025] Referring to Figures 1-6 , an electric clothes hanger wire winding mechanism and an electric clothes hanger provided in this embodiment include an installation top plate 1. A machine box 3 is provided in the middle of the bottom of the installation top plate 1. A wire winding and unwinding assembly 2 is provided on the installation top plate 1 at a position on one side of the machine box 3. A resistance strain gauge 7 is provided on the installation top plate 1 through an installation plate 4. The steel wire rope on the wire winding and unwinding assembly 2 is turned by a guide pulley 6 connected to the resistance strain gauge 7. The resistance strain gauge 7 is electrically connected to a controller in the machine box 3.
[0026] In this utility model, the wire winding mechanism is installed and fixed through the installation top plate 1. The wire winding and unwinding assembly 2 winds and unwinds the steel wire rope. The steel wire rope turns through the guide pulley 6 and then vertically downward. The clothes drying rod is suspended by the steel wire rope. The controller in the machine box 3 controls the wire winding and unwinding assembly 2 to wind and unwind the steel wire rope. The guide pulley 6 is connected to the resistance strain gauge 7 on the mounting plate 4. The resistance strain gauge 7 can detect the stress change of the guide pulley 6. When the steel wire rope breaks during the wire winding process due to relaxation, since the steel wire rope breaks, the clothes drying rod connected to it no longer exerts a pulling force on the steel wire rope, which will cause the pressure of the steel wire rope on the guide pulley 6 to suddenly decrease. At this time, the stress of the guide pulley 6 will change. When the resistance strain gauge 7 detects the stress change, the resistance strain gauge 7 transmits the signal to the controller in the machine box 3, so that the controller controls the wire winding and unwinding assembly 2 to stop wire winding. At the same time, the wire clamping assembly 5 clamps the broken steel wire rope, avoiding the inconvenience of maintenance caused by the continuous wire winding of the wire winding and unwinding assembly 2, and at the same time preventing further damage or potential safety hazards caused by the entanglement and knotting of the steel wire rope;
[0027] It should be noted that in this application, the model of the resistance strain gauge 7 is TSK-1D-120-3A-11L1M2S. The resistance strain gauge 7 is installed in the annular mounting plate 4, and then the guide pulley 6 is connected to the resistance strain gauge 7. It can accurately monitor the stress change when the steel wire rope breaks without affecting the load-bearing of the clothes drying rod. The controller in the machine box 3 adopts the commonly used single-chip microcomputer control structure in the prior art, which can receive the signal of the resistance strain gauge 7 and realize the start-stop control of the wire winding and unwinding assembly 2.
[0028] Specifically, as Figure 1 and Figure 3 shown, a wire clamping assembly 5 is arranged on the installation top plate 1 at the position of the moving path of the steel wire rope. The wire clamping assembly 5 includes an installation frame 51 fixed to the bottom of the installation top plate 1. A cushion block 52 is arranged on the installation frame 51, and an elastic member matching with the cushion block 52 is arranged at the bottom of the installation frame 51.
[0029] Among them, the steel wire rope passes through the installation frame 51 and the space between the cushion block 52 and the elastic member. When the steel wire rope is in normal use, since the bottom of the steel wire rope is connected with a clothes drying rod, under the action of the gravity of the clothes drying rod, the steel wire rope is always in a straight and taut state. At this time, due to the pulling force of the clothes drying rod, the steel wire rope will press down the elastic member on the installation frame 51, making the top of the steel wire rope away from the cushion block 52. The steel wire rope can smoothly pass through the installation frame 51 during the winding and unwinding process. When the steel wire rope breaks, due to the lack of the pulling force of the clothes drying rod, the steel wire rope is no longer in a straight and taut state. At this time, the elastic member resets and cooperates with the cushion block 52 to clamp the steel wire rope, avoiding the continuous winding of the broken steel wire rope by the wire winding and unwinding assembly 2, so that the fracture position of the steel wire rope can be quickly and accurately found during maintenance, facilitating maintenance.
[0030] Specifically, asFigure 3 and Figure 4 As shown in Figure 4 , the elastic member includes a connecting shaft 54 passing through the bottom of the mounting bracket 51. A top head 53 is provided on the connecting shaft 54 below the cushion block 52, and a spring 55 is sleeved on the connecting shaft 54 at a position between the top head 53 and the mounting bracket 51.
[0031] Among them, the connecting shaft 54 passing through the mounting bracket 51 can ensure that the top head 53 can move precisely. When the steel wire rope is in normal use, the steel wire rope presses the top head 53 downward, and the top head 53 compresses the spring 55 on the connecting shaft 54, so that there is enough space between the top head 53 and the cushion block 52 for the steel wire rope to move. When the steel wire rope breaks, the steel wire rope lacks the pressure on the top head 53. At this time, the spring 55 resets and pushes the top head 53 upward, and the top head 53 cooperates with the cushion block 52 to clamp the steel wire rope to prevent it from continuing to wind;
[0032] It should be noted that the cushion block 52 is made of rubber material, so that when the top head 53 and the cushion block 52 clamp the steel wire rope, the friction with the steel wire rope can be increased, ensuring that the top head 53 cooperates with the cushion block 52 to clamp and fix the steel wire rope.
[0033] Specifically, as Figure 4 shown, a first threaded end 541 is provided at the top of the connecting shaft 54, and a connecting screw hole 531 matching the first threaded end 541 is opened at the bottom of the top head 53. A locking nut 543 is provided at the bottom of the connecting shaft 54 through a second threaded end 542.
[0034] Among them, the connecting shaft 54 is detachably connected to the top head 53 through the first threaded end 541 and the connecting screw hole 531, so that the disassembly between the top head 53 and the connecting shaft 54 can be facilitated. When the locking nut 543 is unscrewed from the second threaded end 542, the connecting shaft 54 can be withdrawn from the mounting bracket 51, and thus the disassembly and maintenance of the elastic member can be facilitated, extending the service life of the wire clamping assembly 5.
[0035] Specifically, as Figure 1 and Figure 5 shown, the wire winding and unwinding assembly 2 includes a fixed bracket 21 fixed on the mounting top plate 1. A wire winding cylinder 22 is provided on the fixed bracket 21. A first gear 23 is fixedly connected to the bottom of the wire winding cylinder 22, and a second gear 25 meshing with the first gear 23 is provided on the fixed bracket 21 through a servo motor 24.
[0036] Among them, when the wire winding and unwinding assembly 2 winds and unwinds the wire, the servo motor 24 on the fixed bracket 21 is started, the servo motor 24 drives the second gear 25 to rotate, and then the wire winding cylinder 22 is rotated through the first gear 23 meshing with it. The controller in the machine box 3 controls the forward and reverse rotation of the servo motor 24 to realize the control of the wire winding and unwinding of the wire winding cylinder 22.
[0037] It should be noted that a guide shaft 28 is provided on the fixing bracket 21 through a fixing rod 27. After being guided by the guide shaft 28, the steel wire rope extends horizontally to the guide wheel 6. The guide of the steel wire rope on the winding drum 22 is realized through the guide shaft 28 on the fixing rod 27, so that when the steel wire rope is released and wound, it can move along a predetermined path and direction, avoiding the winding, knotting or deviation of the wire, and at the same time reducing the friction and wear between the steel wire rope and other components on the winding drum 22;
[0038] A protective cover 26 is provided at the bottom of the fixing bracket 21, and both the first gear 23 and the second gear 25 are located inside the protective cover 26. The protective cover 26 is used to protect the transmission structure between the servo motor 24 and the winding drum 22, avoid the damage of the transmission structure, and ensure that the wire winding and unwinding assembly 2 can perform normal wire winding and unwinding operations during use.
[0039] An electric drying rack, the electric drying rack includes the wire winding mechanism of any one of the above. The wire winding mechanism that can perform wire breakage protection can avoid the problem of difficult maintenance caused by continuous winding when the steel wire rope on the drying rack breaks.
[0040] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
