[0002] In modern clothes drying rack designs, the retractor and drive cord are the core components that enable the rack to be raised and lowered. The retractor adjusts the rack's position by winding the drive cord and requires sufficient power to overcome the rack's weight for smooth raising and lowering. However, as the weight of the clothes on the rack increases, the power required by the retractor also increases, driving up the cost of the equipment. Summary of the Invention

[0003] The purpose of the utility model is to provide a clothes drying machine, which has the advantages of reducing the workload of a retractor, lowering the power of the retractor, and effectively reducing the production cost of the equipment.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A clothes drying machine, comprising:

[0006] Host;

[0007] A retractor is provided on the main machine; the retractor includes a drive rope;

[0008] a drying rack, the drying rack being controlled by the retractor to move relative to the host;

[0009] Also includes:

[0010] A crossbar is provided on the drying rack, and a first groove is provided on the crossbar;

[0011] The movable pulley is arranged in the first slot body, the first end of the driving rope is fixed to the retractor, and the second end passes around the movable pulley and extends to be connected to the main machine.

[0012] It is further configured that the movable pulley is arranged at the middle position of the cross bar.

[0013] It is further configured that the main machine is further provided with a steering wheel, and the steering wheel is located upstream of the movable pulley along the extending direction of the driving rope.

[0014] It is further configured that the surface where the steering wheel is located intersects with the surface where the movable pulley is located.

[0015] It is further configured that the steering wheel is located at a projected position on the side of the main machine, at a middle position of the main machine along the width direction, and the steering wheel and the movable pulley are located on the same vertical plane.

[0016] It is further configured that the steering wheel is located at a projected position on the side of the main machine, and the length from the midpoint of the main machine in the width direction is equal to the radius of the movable pulley.

[0017] It is further arranged that the driving ropes located upstream and downstream of the movable pulley are arranged parallel to each other.

[0018] It is further configured that the host includes a bottom plate, the bottom plate is provided with a hole, the drive rope passes through the hole, and the second end of the drive rope is connected to the outside of the bottom plate.

[0019] Further configuration: the main machine includes a bottom plate, the bottom plate is provided with two holes, and the upstream and downstream parts of the driving rope located at the movable pulley respectively pass through the two holes.

[0020] Further setting: the two holes are located in the same plane.

[0021] It is further configured that: there are two movable pulleys, and there is a distance between the two movable pulleys.

[0022] It is further configured that the spacing is not less than half the length of the cross bar.

[0023] It is further configured that the retractor is provided with a second end of the driving rope which is connected to the main machine after passing through two movable pulleys in sequence.

[0028] In summary, the present invention has the following beneficial effects:

[0029] First, in this utility model, a movable pulley is added to the crossbar. The retractor drives the drive rope around the movable pulley before connecting to the main machine. This changes the force distribution of the drive rope. By shortening the lever arm and reducing the torque, the torque that the retractor must overcome is reduced. This reduces the retractor's power requirement by half, reducing the retractor's workload and power requirements, effectively lowering the equipment's production costs. Furthermore, after passing around the movable pulley, the drive rope forms a double-line support, enhancing structural stability.

[0030] Secondly, in the present invention, the movable pulley is hidden in the first groove, preventing the movable pulley structure from being exposed, making the design more compact. This not only saves space, but also reduces possible collisions or external interference, making the overall appearance of the clothes drying machine more concise.

[0031] Third, in the present invention, when the clothes hanging on the clothes drying machine are subjected to heavy force, the scissors frame will be deformed to a certain extent. The limiting ring on the scissors frame is sleeved on the driving rope. The limiting ring increases the constraint between the scissors frame and the driving rope, reducing the deformation of the scissors frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] A clothes drying machine, such as Figure 1 and Figure 2 As shown, the main unit 100 and the drying rack 201 are provided. The drying rack 201 has a first position close to the main unit 100 and a second position away from the main unit 100. In this embodiment, the main unit 100 and the drying rack 201 are preferably stacked. In the conventional installation position, the main unit 100 is fixed to the floor structure, and the drying rack 201 is located below the main unit 100 and rises and falls relative to the side of the main unit 100.

[0048] Furthermore, the clothes drying machine includes a retractor 400, which is mounted on the main unit 100. The clothes drying rack 201 is controlled by the retractor 400 to move relative to the main unit 100. In this embodiment, the movement of the clothes drying rack 201 relative to one side of the main unit 100 is a lifting motion, preferably a linear lifting motion. The retractor 400 includes a drive cord 401, which is adapted to retract and extend the drive cord 401. The retractor 400 controls the extension and retraction of the drive cord 401, thereby causing the clothes drying rack 201 to rise and fall relative to the main unit 100.

[0049] On the basis of the above embodiment, as a further limited embodiment, Figure 3As shown, the clothes drying machine also includes a crossbar 202, which is mounted on the drying rack 201. The crossbar 202 includes a first slot 203 with a notch facing the main unit 100. A movable pulley 403 is mounted on the crossbar 202 and is rotatably connected to the interior of the first slot 203 via a rotating shaft 204. A drive rope 401 has a first end secured to a retractor 400, while a second end passes over the movable pulley 403 and extends to the main unit 100. The retractor 400 reels the first end, shortening the distance between the first and second ends. The drive rope 401 winds around the bottom of the movable pulley 403, thereby raising the movable pulley 403 and the crossbar 202. Conversely, when the retractor 400 unwinds the rope, the drive rope 401 lowers the crossbar 202. In this embodiment, the crossbar 202 is integrally connected to the drying rack 201, and the drying rack 201 and the crossbar 202 rise and fall together.

[0050] There is no restriction on the specific shape of the host 100. In this embodiment, the cross section of the host 100 is a rectangle. It has long sides and wide sides. In this embodiment, there are two crossbars 202, and these crossbars 202 are arranged on both sides of the host 100 along the length direction. There is no restriction on the arrangement position of the movable pulley 403. In this embodiment, the movable pulley 403 is arranged in the middle position in the length direction of the crossbar 202. Preferably, the movable pulley 403 is arranged at the midpoint of the crossbar 202. The movable pulley 403 being at the midpoint can maintain the balance of the crossbar 202. A drying rack 201 is provided between the two crossbars 202. The drying racks 201 on both sides also maintain a mutually balanced state according to the arrangement position of the movable pulley 403.

[0051] On the basis of the above embodiment, as a further limited embodiment, Figure 3 As shown, the main unit 100 is further provided with a steering wheel 402. The specific structure of the steering wheel 402 is not limited. In this embodiment, the steering wheel 402 is located upstream of the movable pulley 403 along the extension path of the drive rope 401. The steering wheel 402 is a fixed pulley that is rotatably connected to the main unit 100. The second end of the drive rope 401 passes around the fixed pulley before being redirected. The drive rope 401 has a portion parallel to the main unit 100 and a portion perpendicular to the main unit 100 after passing through the fixed pulley.

[0052] like Figure 3As shown, the surface where the steering wheel 402 is located intersects with the surface where the movable pulley 403 is located. In this embodiment, the surface where the steering wheel 402 is located is the surface formed by the wheel during rotation. From the perspective given in the figure, the rotating surface of the steering wheel 402 is the surface parallel to the main unit 100, and the rotating surface of the steering wheel 402 extends downward and intersects with the movable pulley 403 on the lower side. In this embodiment, the surface where the steering wheel 402 is located is perpendicular to the surface where the movable pulley 403 is located. There is no restriction on the specific position of the steering wheel 402. In this embodiment, the steering wheel 402 is located at both ends of the length direction of the main unit 100, and the steering wheel 402 is located at a projected position on the side 105 of the main unit 100, located in the middle position of the main unit 100 along the width direction, preferably, located at the midpoint position of the main unit 100 along the width direction. The position where the steering wheel 402 is fixed at the midpoint can be relatively fixed or relatively movable. For example, when the steering wheel 402 is installed, a certain movable distance is left along the axial direction. In this embodiment, reference Figure 2 The side surface 105 of the host 100 specifically refers to the two side surfaces 105 along the length direction of the host 100, and may also be the side surfaces 105 exposed to the outside of the host 100. As an alternative embodiment, refer to Figure 1 The side surface 105 can be a structure hidden within the end of the main unit 100, such as on the sheet metal member 101 at the end of the main unit 100. In this embodiment, the steering wheel 402 and the movable pulley 403 are located on the same vertical plane. For example, the steering wheel 402 is located at the projected position on the side surface 105 of the main unit 100, at the midpoint of the width of the main unit 100, and the movable pulley 403 is located at the midpoint of the crossbar 202. The center of the two wheels falls exactly on the symmetry plane of the clothes drying machine. Therefore, the steering wheel 402 and the movable pulley 403 are located on the same vertical plane.

[0053] like Figure 3 、 Figure 4 and Figure 5 As shown, the main unit 100 includes a base plate 104 with a hole 103 defined therein. The upstream portion of the movable pulley 403 passes through the hole 103, passes around the movable pulley 403, and then connects to the outside of the base plate 104. Specifically, the main unit 100 has sheet metal members 101 on both sides of its length, which are fixedly connected to the base plate 104 on the outside. The second end of the drive rope 401 is connected to the outside of the base plate 104, specifically to the sheet metal member 101. An end cap 102 is provided on the outside of the sheet metal member 101, which is adapted to shield the sheet metal member 101, giving the main unit 100 a sleek and simple appearance.

[0054] As an alternative embodiment, Figure 7As shown, the steering wheel 402 is located at a projected position on the side surface 105 of the main unit 100, and its length from the midpoint of the main unit 100 along the width direction is equal to the radius of the movable pulley 403. This allows the drive rope 401 located upstream of the movable pulley 403 to be vertically tangential to the movable pulley 403. Further, the drive rope 401 downstream of the movable pulley 403 is vertically connected to the main unit 100, so that the drive ropes 401 upstream and downstream of the movable pulley 403 are parallel to each other. It should be noted that the portion upstream of the movable pulley 403 referred to herein refers to the drive rope 401, specifically the vertical portion located between the steering wheel 402 and the movable pulley 403.

[0055] like Figure 8 As shown, the main unit 100 includes a base plate 104 having two holes 103 formed therein. The upstream and downstream portions of the drive rope 401 located at the movable pulley 403 respectively pass through the two holes 103. In this embodiment, the two holes 103 are located on the same plane, and the vertical portion of the drive rope 401 located between the deflection wheel 402 and the movable pulley 403 and the downstream portion of the movable pulley 403 are parallel to each other.

[0056] As an alternative embodiment, Figure 9 As shown, there are two movable pulleys 403, and there is a distance between the two movable pulleys 403. In this embodiment, preferably, the distance is not less than half the length of the cross bar 202. So that the two movable pulleys 403 are arranged at both ends of the cross bar 202.

[0057] On the basis of the above embodiment, as a further limited embodiment, Figure 9 As shown, the clothes drying machine also includes a scissor frame 300, which connects the main unit 100 and the crossbar 202. The crossbar 202 is provided with a second slot 205, into which a portion of the scissor frame 300 is connected. Two movable pulleys 403 are disposed within the first slot 203. Therefore, the scissor frame 300 and the drive rope 401 are located on different planes, and their motion paths do not interfere with each other.

[0058] The specific structure of the scissor frame 300 is not limited. In this embodiment, the scissor frame 300 is a scissor-type lifting mechanism. As an alternative embodiment, the scissor frame can also be replaced with a rack and pinion transmission mechanism. As an alternative embodiment, it can also be replaced with a hydraulic lever, a pneumatic lever, an oil pressure lever, or an electric lifting lever.

[0059] In this embodiment, reference Figure 9The retractor 400 is provided with one, and the second end of the drive rope 401 is passed around two movable pulleys 403 in sequence and then connected to the host 100. As an alternative embodiment, there are two retractors 400, each of which is provided with a drive rope 401, and each drive rope 401 is passed around a corresponding movable pulley 403.

[0060] There is no limitation on the specific material of the driving rope 401. In this embodiment, the driving rope 401 is a steel rope. As an alternative embodiment, the driving rope 401 can also be a synthetic fiber rope, such as a nylon rope.

[0061] In this embodiment, the scissors frame 300 is provided with a restraining ring 303. The restraining ring 303 is installed on the scissors frame 300, and the upstream and / or downstream portions of the drive rope 401 located on the movable pulley are passed through the restraining ring 303. When the clothes drying machine is subjected to heavy loads, the restraining ring 303 on the scissors frame 300 is fitted over the drive rope 401. The restraining ring 303 increases the constraint between the scissors frame 300 and the drive rope 401, thereby reducing deformation of the scissors frame 300.

[0062] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
