Description

Technical Field

[0001] This utility model relates to the field of electric clothes drying rack technology, specifically a stable transmission box for electric clothes drying racks. Background Technology

[0002] Retractable clothes drying racks are common drying devices in modern homes, mainly divided into hand-cranked and electric types. During the raising and lowering process, the hanging cord needs to be wound up. The most direct design approach is to use a motor to drive the reel. However, motor speeds are generally high and difficult to control, easily leading to rapid winding and unwinding of the hanging cord. To solve this problem, technicians introduced gear sets into the transmission box where the motor is located to slow down the winding and unwinding of the hanging cord. However, the limited size of the transmission box restricts the number and diameter of the gears, thus limiting the speed-reducing effect. This results in the clothes drying rack being raised and lowered very quickly, and the inertia at this speed leads to poor stability, especially when clothes are hanging on it. Therefore, how to more effectively reduce the speed of winding and unwinding the hanging cord, further avoid rapid raising and lowering when clothes are hanging on the rack, and ultimately improve the stability of the clothes drying rack has become an increasingly urgent problem for relevant technicians. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a stable transmission box for electric clothes drying racks.

[0004] A stable transmission box for an electric clothes drying rack includes an upper box and a lower box. The upper box has a first mounting groove in the middle, a second mounting groove symmetrically arranged above the first mounting groove, and third mounting grooves symmetrically arranged on both sides of the first mounting groove. A motor is fixedly installed inside the first mounting groove, and a worm gear is fixedly installed at the end of the motor's output shaft. A worm wheel and a first gear are rotatably installed inside the second mounting groove, the first gear being coaxial with the worm wheel and located in front of the worm wheel. A second gear is rotatably installed inside the third mounting groove, meshing with the first gear. The worm wheel meshes with the worm gear. A winding wheel is fixedly installed behind the second gear. Cable outlets are symmetrically arranged at the lower part of the upper box, and the cable outlets communicate with the third mounting grooves.

[0005] Furthermore, a crossbeam is provided at the lower part of the upper box, and a transition device is provided below the cable outlet and above the lower box. The lower part of the transition device is rotatably sleeved with the crossbeam. A stop bar is provided inside the transition device. A torsion spring is sleeved on the surface of the crossbeam. One end of the torsion spring contacts the lower box, and the other end of the torsion spring contacts the stop bar. A rotating sleeve is rotatably provided on the upper part of the transition device.

[0006] Furthermore, a magnet is provided at the lower end of the transition device, a circuit board is fixedly installed inside the lower housing, a Hall sensor is fixedly installed at the upper part of the circuit board, a detection unit is fixedly installed at the upper part of the Hall sensor, and the magnet and the detection unit are positioned correspondingly.

[0007] Furthermore, a lower insert block is symmetrically fixedly arranged on the upper part of the lower box body, and an upper insert block is symmetrically fixedly arranged on the lower part of the upper box body. The lower insert block is inserted into the upper insert block. A screw hole is provided on the upper part of the lower box body, and a screw is provided inside the screw hole. The screw is threadedly connected to the screw hole and the upper box body.

[0008] Furthermore, a front cover is provided at the front of the lower box body, the front cover is positioned corresponding to the motor, and slots are symmetrically provided on the upper part of the upper box body, with guide grooves symmetrically provided between the slots.

[0009] The beneficial effects of this utility model's stable transmission box for electric clothes drying racks are as follows:

[0010] 1. The design of the worm gear and the first gear being coaxial, the first gear being located in front of the worm gear, and the winding wheel being located behind the second gear, combined with the vertical design of the worm, effectively ensures full utilization of the space in the second and third mounting slots, effectively reduces the restrictions on the number and diameter of gears, effectively achieves more effective speed reduction for the winding and unwinding of the hanging line, and effectively improves the stability of the electric clothes drying rack.

[0011] 2. When clothes are hanging on the clothes rack, the magnet is separated from the detection unit. When no clothes are hanging, the magnet is directly above the detection unit. This allows the Hall sensor to transmit relevant signals to the circuit board, causing the motor to output a corresponding speed. The output speed is low when clothes are hanging and high when no clothes are hanging. The transmission, processing, and control of the output speed of the signal are not within the scope of this application. However, the transition device, magnet, detection unit, Hall sensor, and circuit board provide a good structural foundation for the realization of this function. This effectively avoids rapid lifting and lowering when clothes are hanging on the clothes rack, further improving the stability of the electric clothes rack. Attached Figure Description

The lower part of the transition device 10 is rotatably sleeved with the crossbeam 15. A stop bar 26 is provided inside the transition device 10. A torsion spring is sleeved on the surface of the crossbeam 15. One end of the torsion spring contacts the lower box 4, and the other end of the torsion spring contacts the stop bar 26. A rotating sleeve 14 is rotatably provided on the upper part of the transition device 10.

[0024] Furthermore, a magnet 23 is provided at the lower end of the transition device 10, a circuit board 24 is fixedly provided inside the lower box 4, a Hall sensor 21 is fixedly provided on the upper part of the circuit board 24, a detection unit 22 is fixedly provided on the upper part of the Hall sensor 21, and the magnet 23 corresponds to the position of the detection unit 22.

[0025] Furthermore, the lower box body 4 is symmetrically fixed with a lower insertion block 11 on the upper part, and the upper box body 5 is symmetrically fixed with an upper insertion block 18 on the lower part. The lower insertion block 11 is inserted into the upper insertion block 18. The lower box body 4 is provided with a screw hole 25 on the upper part, and a screw is provided inside the screw hole 25.

[0027] The working principle of the stable transmission box for an electric clothes drying rack of this utility model is as follows: The suspension line is wound on the winding wheel 12, and the free end passes over the rotating sleeve 14 and is then tied to the clothes drying rack. In the initial state, there are no clothes hanging on the clothes drying rack. At this time, the magnet 23 is in contact with the detection unit 22, and the Hall sensor 21 transmits the signal to the circuit board 24, so that the motor 9 can output high speed, thereby increasing the lifting speed of the clothes drying rack. After the user hangs clothes on the clothes drying rack, the magnet 23 separates from the detection unit 22, and the Hall sensor 21 transmits the signal to the circuit board 24, so that the motor 9 can only output low speed, thereby avoiding rapid lifting when there are clothes on the clothes drying rack. The clothes rack is raised and lowered. After clothes are hung on it, the torsion spring changes from its natural state to a tightened state. After the clothes are removed, the torsion spring automatically returns to its natural state. The specific transmission process is as follows: the motor 9 is started, the output shaft of the motor 9 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 8 to rotate, the worm wheel 8 and the first gear 7 rotate synchronously, the first gear 7 drives the second gear 6 to rotate, the second gear 6 and the winding wheel 12 rotate synchronously, and the winding wheel 12 releases or retracts the hanging line. Once the clothes rack is moved to a suitable height, the motor 9 can be turned off. The release and retraction of the hanging line correspond to the forward and reverse rotation of the motor 9, respectively. The reversible motor 9 is existing technology and will not be described in detail here.
