Description

Technical Field

[0001] This utility model relates to the field of clothes drying equipment technology, and in particular to a wire pressing module for pressing down the wire rope when the clothes drying machine is raising and lowering the clothes drying rack, a winding device using the wire pressing module, and a clothes drying machine having the winding device. Background Technology

[0002] The clothes drying rack consists of a main unit and a clothes rack, with the main unit connected to the clothes rack via steel cables. When clothes need to be dried, the main unit loosens the steel cables, allowing the clothes rack to descend under gravity. Once it reaches the predetermined height, the main unit tightens the steel cables to secure the clothes rack, making it easy to hang clothes on it. When clothes are no longer needed, the clothes rack is raised close to the main unit, freeing up space on balconies or other areas occupied by the drying rack.

[0003] The main unit is equipped with a winding device, the main functional component of which is a winding wheel with grooves for the wire rope. One end of the wire rope is fixed to the winding wheel, and the other end is fixed to the clothes rack. A motor drives the winding wheel to rotate, causing the wire rope to wind around or be pulled off the winding wheel, thus enabling the clothes rack to be retracted or extended.

[0004] The steel wire rope has a clearance fit with the groove. When the steel wire rope is wound around the groove, if there are no clothes hanging on the clothes rack connected to it (i.e., the only load on the steel wire rope is the clothes rack), the steel wire rope will loosen on the winding reel due to its own elastic tension, causing the fit with the groove to loosen. When the clothes rack rises or falls, the loose steel wire rope will experience friction with the gearbox housing, easily leading to the steel wire rope jumping out of the groove.

[0005] To address this issue, existing technologies provide a corresponding pressure wheel for each winding reel, using these pressure wheels to limit the movement of the wire rope. However, the pressure wheels in existing technologies have the following problems: the position between the pressure wheel and the winding reel is relatively fixed. When the position is set according to the needs of the wire rope when it is stationary, the distance between the pressure wheel and the winding reel needs to be closer. However, when the wire rope needs to be pulled out or wound, this distance will generate significant resistance to the wire rope, affecting its normal movement. Conversely, if the relative position of the pressure wheel and the winding reel is set according to the needs of the wire rope when it is moving, the distance between the pressure wheel and the winding reel is relatively large. Under tension, the wire rope may detach from the winding reel, resulting in the wire rope not being able to completely avoid jumping off the groove during winding and unwinding. Utility Model Content

[0006] To address the issue of the positional arrangement between the pressing wheel and the winding wheel in existing technologies, this application provides a pressing module that allows the position between the pressing wheel and the winding wheel to be automatically adjusted.

[0007] The crimping module provided in this application includes a crimping wheel and a crimping wheel mounting bracket. The crimping wheel includes a cylindrical crimping wheel body and a crimping wheel shaft for rotating the crimping wheel body. The crimping wheel mounting bracket includes a first end and a second end of the crimping wheel mounting bracket arranged in parallel. The first end of the crimping wheel mounting bracket is provided with a first guide groove and a first guide hole along the first guide groove. The second end of the crimping wheel mounting bracket is provided with a second guide groove and a second guide hole along the second guide groove. It also includes a first crimping wheel magnet, a second crimping wheel magnet, a third crimping wheel magnet, and a fourth crimping wheel magnet. The pressure roller magnets are as follows: the second pressure roller magnet is fixed to the second end of the first guide groove, the fourth pressure roller magnet is fixed to the second end of the second guide groove, the first pressure roller magnet and the third pressure roller magnet are respectively fixed to both ends of the pressure roller shaft, the two ends of the pressure roller shaft pass through the first guide hole and the second guide hole respectively, the first pressure roller magnet is located in the first guide groove, the third pressure roller magnet is located in the second guide groove, the first pressure roller magnet and the second pressure roller magnet are arranged opposite each other with the same polarity, and the third pressure roller magnet and the fourth pressure roller magnet are arranged opposite each other with the same polarity.

[0008] The wire pressing module provided in this application embodiment, when installed on the winding device, allows the first and third wire pressing wheel magnets, under the repulsive force of the second and fourth wire pressing wheel magnets respectively, to press against the ends of the first and second guide holes away from the second and fourth wire pressing wheel magnets. This provides a force to the wire pressing wheel body that presses against the wire rope between the wire pressing wheel and the winding wheel, allowing the wire rope to better fit against the wire rope groove of the winding wheel. When the wire rope needs to be pulled, the outward pull of the wire rope generates a thrust on the wire pressing wheel body. This thrust causes the wire pressing wheel body to move along the first and second guide holes towards the second end of the guide groove. During this movement, the repulsive force between the second and first wire pressing wheel magnets, and between the fourth and third wire pressing wheel magnets, increases, eventually balancing the thrust of the wire rope. At this point, the gap between the wire pressing wheel and the winding wheel increases, facilitating smoother wire rope movement. When the wire rope is stationary, the pressure wheel will reduce the gap between the pressure wheel and the winding wheel under the action of repulsive force, making the wire rope more closely close to the wire rope groove of the winding wheel.

[0009] Based on the same inventive purpose, this application provides a winding device, including a gearbox housing, a winding wheel mounting cavity on the gearbox housing, a wire rope inlet and outlet for the wire rope to pass through the side wall of the winding wheel mounting cavity, and a winding wheel on the winding wheel mounting cavity; the gearbox housing also has a wire pressing module mounting position for each winding wheel, and a wire pressing module as described above is installed on each wire pressing module mounting position, wherein the wire pressing wheel mounting bracket is fixed on the wire pressing module mounting position, so that the wire pressing wheel body is close to the winding wheel.

[0010] The winding device provided in this application embodiment is an improvement over existing clothes drying rack winding devices. The main improvement is in the pressure roller module, which allows for adjustment of the distance between the pressure roller and the winding roller. When the wire rope is stationary, the distance between the pressure roller and the winding roller is reduced, ensuring the wire rope is close to the groove, preventing it from jumping out of the groove when moving. Simultaneously, when the wire rope is moving, the gap between the pressure roller and the winding roller is increased, allowing the wire rope to move more smoothly.

[0011] Based on the same inventive purpose, this application also provides a clothes drying rack. It includes a main unit and a clothes rack. The main unit is equipped with a winding device as described above. Each winding wheel of the winding device has a steel wire rope wound around it. The first end of the steel wire rope is fixed to a steel wire rope groove on the winding wheel close to the drive gear, and the second end of the steel wire rope is fixed to the clothes rack. The steel wire rope is wound around the winding wheel along the steel wire rope groove.

[0012] The clothes drying rack provided in this application focuses on improving the wire pressing module in its winding device. This improvement allows for adjustment of the distance between the wire pressing wheel and the winding wheel. When the wire rope is stationary, the distance between the two wheels is reduced, ensuring the wire rope is close to the groove and preventing it from jumping out of the groove during movement, which would affect the clothes drying rack's operation. Simultaneously, when the wire rope is moving, the gap between the wire pressing wheel and the winding wheel is increased, allowing for smoother wire rope movement. Attached Figure Description

[0016] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the accompanying drawings and specific circumstances.

[0018] The technical solution of this application will now be described in detail with reference to the accompanying drawings.

[0019] To address the problem of existing clothes drying racks where the wire rope detaches from the groove on the winding reel due to elastic tension, the current method uses a pressure roller for each winding reel to limit the wire rope tension. However, the inventors of this application have discovered that the relative position between the pressure roller and the winding reel is fixed. The space required for this differs depending on whether the wire rope is moving or stationary. This causes the pressure roller to interfere with the movement of the wire rope, thus affecting the adjustment of the clothes drying rack. In other words, adjusting the clothes drying rack in existing clothes drying racks is not as smooth as it could be due to the influence of the pressure roller.

[0020] Based on this, this application provides an improved clothes drying rack. For example... Figures 1 to 8As shown in the embodiment of this application, the clothes drying rack includes a main unit (not shown) and a clothes rack (not shown). The main unit is equipped with a motor (not shown) and a winding device 10. The winding wheel 200 of the winding device 10 has a wire rope groove 221. One end of the wire rope 400 is fixed to the winding wheel. Driven by the motor, the winding wheel can wind the wire rope 400 around the wire rope groove 221 or release it from the wire rope groove 221. The other end of the wire rope 400 is fixed to the clothes rack. The clothes drying rack provided in this application may also include components that perform other functions, such as a transmission mechanism located at both ends of the main unit and the clothes rack, mainly providing buffering, balancing, and protection for the opening and closing of the clothes rack; and a control unit located on the main unit, used to install and set control programs, and receive control commands sent by devices such as remote controls and smart terminals, controlling the motor to work according to the set process. The clothes drying rack provided in this application may also include other functions and components that can be achieved by existing technology, such as disinfection, air blowing, and heating. Please refer to the solutions provided by existing technology, which will not be elaborated here.

[0021] The clothes drying rack provided in this application focuses on improving its winding device 10 to solve the problem of the influence of the fixed position of the pressure wheel on the movement of the wire rope in existing clothes drying racks. The winding device 10 provided in this application includes a gearbox housing 100 that serves as the mounting base for various functional components. The gearbox housing 100 is provided with a winding wheel mounting cavity 110. The winding wheel mounting cavity 110 can be a generally square cavity. In the preferred embodiment provided in this application, the shape of the winding wheel mounting cavity 110 is adapted to the shape of the winding wheel 200, and is generally cylindrical. The side wall of the winding wheel mounting cavity 110 is provided with a wire rope inlet / outlet 120 for the wire rope to pass through. In the preferred embodiment provided in this application, a winding wheel mounting cavity 110 is provided on each side of the gearbox housing 100. Each winding wheel mounting cavity 110 is provided with a winding wheel shaft bearing 111. A winding wheel 200 is installed on each winding wheel mounting cavity 110 by matching the winding wheel shaft 240 provided on the winding wheel 200 with the winding wheel shaft bearing 111. When the gearbox housing 100 is provided with two winding wheel mounting cavities 110, the two wire rope inlets and outlets 120 provided on the side wall of the winding wheel mounting cavity 110 are symmetrically arranged and far away from the other winding wheel. In this way, when a winding wheel 200 is installed in each winding wheel mounting cavity 110, the wire rope 400 wound on the winding wheel 200 can extend from different directions, and each wire rope 400 controls the lifting and lowering of one end of the clothes rack.

[0022] The winding device 10 provided in this application embodiment is further provided with a wire pressing module mounting position 130 corresponding to each winding wheel in the gearbox housing. A wire pressing module 300 is installed on each wire pressing module mounting position 130 to further limit the wire rope 400, so that the wire rope 400 can be wound more smoothly on each wire rope groove 221 in sequence.

[0023] The crimping module 300 provided in this application includes a crimping wheel 310 and a crimping wheel mounting bracket 320. The crimping wheel 310 includes a crimping wheel body 311 and a crimping wheel shaft 312 for rotating the crimping wheel body 311. The crimping wheel mounting bracket 320 includes a first end 321 and a second end 322 of the crimping wheel mounting bracket arranged in parallel. The first end of the crimping wheel mounting bracket is provided with a first guide groove 3211 and a first guide hole 3212 along the first guide groove 3211. The second end 322 of the crimping wheel mounting bracket is provided with a second guide groove 3221 and a second guide hole 3222 along the second guide groove 3221. It also includes a first crimping wheel magnet 331, a second crimping wheel magnet 332, a third crimping wheel magnet 333, and a fourth crimping wheel magnet 3222. The first pressure wheel magnet 334 and the second pressure wheel magnet 332 are fixed to the second end of the first guide groove 3211, and the fourth pressure wheel magnet 334 is fixed to the second end of the second guide groove 3221. The first pressure wheel magnet 331 and the third pressure wheel magnet 333 are respectively fixed to the two ends of the pressure wheel shaft 312. The two ends of the pressure wheel shaft 312 pass through the first guide hole 3212 and the second guide hole 3222, respectively. The first pressure wheel magnet 331 is located in the first guide groove 3211, and the third pressure wheel magnet 333 is located in the second guide groove 3221. The first pressure wheel magnet 331 and the second pressure wheel magnet 332 are arranged opposite each other with the same polarity, and the third pressure wheel magnet 333 and the fourth pressure wheel magnet 334 are arranged opposite each other with the same polarity. That is, if the end of the first pressing wheel magnet 331 facing the second pressing wheel magnet 332 is the N pole, then the end of the second pressing wheel magnet 332 facing the first pressing wheel magnet 331 is also the N pole; if the end of the first pressing wheel magnet 331 facing the second pressing wheel magnet 332 is the S pole, then the end of the second pressing wheel magnet 332 facing the first pressing wheel magnet 331 is also the S pole. The third pressing wheel magnet 333 and the fourth pressing wheel magnet 334 are configured similarly. The pressing wheel mounting bracket 320 can be fixed on the pressing module mounting position 130. When the pressing wheel mounting bracket 320 is fixed on the pressing module mounting position 130, the entire pressing wheel mounting bracket 320 is parallel to the winding wheel 200, so that the first guide groove 3211 and the second guide groove 3221 are both perpendicular to the winding wheel 200. Meanwhile, in the first guide groove 3211 and the second guide groove 3221, the first end of the first guide groove 3211 is close to the winding wheel 200, and the second end of the first guide groove 3211 is relatively far away from the winding wheel 200. Similarly, the first end of the second guide groove 3221 is close to the winding wheel 200, and the second end of the second guide groove 3221 is also relatively far away from the winding wheel 200. Therefore, the pressure wheel installed between the first guide hole 3212 and the second guide hole 3222 of the pressure wheel mounting bracket is close to the winding wheel 200, and the axis of the pressure wheel is parallel to that of the winding wheel. The gap between the pressure wheel and the winding wheel forms a limiting space for the wire rope.

[0024] The wire pressing module 300 provided in this application, when the wire rope 400 is stationary, generates a repulsive force between the second wire pressing wheel magnet 332 and the fourth wire pressing wheel magnet 334 on the first wire pressing wheel magnet 331 and the third wire pressing wheel magnet 333, respectively. This pushes the wire pressing wheel body 311 to press tightly against the wire rope 400, applying pressure to the wire rope 400 and making the wire rope better fit on the wire rope groove 221. During the lifting and lowering process of the clothes rack, in addition to tension, the wire rope also generates an outward thrust, which can push the wire pressing wheel body along the guide hole towards the second wire pressing wheel magnet 332 and the fourth wire pressing wheel magnet 334. Simultaneously, the first wire pressing wheel magnet 331 and the third wire pressing wheel magnet 333 will move along the first guide groove 3211 and the second guide groove 3221, respectively. This expands the limiting space between the wire pressing wheel and the winding wheel, making it easier for the wire rope to enter and exit, and facilitating smoother wire rope movement. As the first and third pressure wheel magnets approach the second and fourth pressure wheel magnets respectively, the repulsive force between the first and second pressure wheel magnets increases, as does the repulsive force between the third and fourth pressure wheel magnets. This eventually causes the confined space to expand to a reasonable size and then stop increasing, maintaining its limiting effect on the wire rope. When the winding wheel stops rotating and the wire rope is stationary, the additional thrust of the wire rope on the pressure wheel disappears. Under the influence of the magnetic repulsive force, the pressure wheel moves closer to the winding wheel again, further confining the wire rope located between the winding wheel and the pressure wheel. Therefore, the pressure module provided in this application can confine the wire rope close to the winding wheel when it is stationary, preventing the wire rope from jumping out of its groove due to excessive distance from the winding wheel and friction with the gearbox housing when starting. It can also open the limiting space between the pressure wheel and the winding wheel after the wire rope starts moving, allowing for smoother wire rope movement.

[0025] In the preferred embodiment provided in this application, the wire pressing module 300, including the wire pressing wheel mounting bracket 320, the wire pressing wheel body 311, and the wire pressing wheel shaft 312, are all made of non-magnetic materials. Using non-magnetic materials avoids magnetization by the wire pressing wheel magnets, thereby controlling the interaction between the wire pressing wheel magnets within the scope of the wire pressing module, while the impact on the wire rope is negligible.

[0026] The inventors of this application discovered in further research that when the wire rope 400 is in motion, the friction between it and the pressure wheel 310 is insufficient to drive the pressure wheel 310 to rotate, causing slippage between the wire rope 400 and the pressure wheel 310, resulting in wear on the pressure wheel 310. When the wear is significant, the surface of the pressure wheel 310 becomes uneven, causing the clothes drying rack to produce considerable noise during adjustment.

[0027] Therefore, the inventors have further improved the wire pressing module 300 provided in this application. In a further improved embodiment, a groove is provided on the cylindrical outer surface of the wire pressing wheel body 311. By providing the groove, the maximum static friction between the wire pressing wheel 310 and the wire rope 400 is increased, so that when the wire rope 400 starts, the maximum static friction is sufficient to drive the wire pressing wheel 310 to rotate. This ensures that there is almost no slippage or wear between the wire rope 400 and the wire pressing wheel 310, guaranteeing a smooth fit between the wire pressing wheel 310 and the wire rope 400.

[0028] In this embodiment, the grooves on the outer surface of the pressure wheel body 311 are preferably provided in two ways. In the first embodiment, a plurality of first grooves 315 are provided along the cylindrical outer surface of the pressure wheel body, extending from the first surface 313 of the pressure wheel body 311 to the second surface 314 of the pressure wheel body 311. The first grooves 315 are parallel to the central axis of the pressure wheel body 311. Since the outer surface of the pressure wheel body 311 is cylindrical, and the outer surface of the wire rope 400 is also approximately cylindrical, the pressure wheel 310 and the wire rope 400 are approximately tangential, that is, there is point contact or a short line contact between the pressure wheel 310 and the wire rope 400. This is also the reason for the low friction between the pressure wheel and the wire rope. When a first groove 315 is provided on the cylindrical outer surface of the pressure wheel, when the pressure wheel and the wire rope are stationary, both sides of the first groove 315 will be in tangential or line contact with the wire rope, effectively doubling the contact area and the maximum static friction. This allows the friction between the wire rope and the pressure wheel to rotate when the wire rope begins to move, thus preventing sliding friction and wear between the wire rope and the pressure wheel. This also makes the movement between the pressure wheel and the wire rope smoother and reduces noise.

[0029] In a preferred second embodiment, a plurality of wire rope receiving grooves are provided along the cylindrical outer surface of the pressing wheel body 311, and the wire rope receiving grooves are parallel to the first surface 313 of the pressing wheel body. When the cylindrical outer surface of the pressing wheel body 311 is set as the wire rope receiving groove, when the pressing wheel and the wire rope are in a stationary state, there is point contact at the top or short line contact between the pressing wheel and the wire rope, and there is also a line contact between the two sides of the wire rope receiving groove and the wire rope. Therefore, the contact area between the pressing wheel and the wire rope is increased, further increasing the friction between the pressing wheel and the wire rope, so that the wire rope can easily drive the pressing wheel to rotate. This avoids sliding friction and wear between the wire rope and the pressing wheel, making the movement between the pressing wheel and the wire rope smoother and avoiding noise.

[0030] The winding device 10 provided in this application embodiment also improves its winding wheel 200. The winding wheel 200 provided in this application embodiment includes a drive gear 210, and a winding wheel body 220 is provided on one side of the drive gear 210. In this application example, the winding wheel body 220 is preferably cylindrical, that is, the winding wheel body 220 is a cylinder extending from one side of the drive gear 210, which can be integrally formed with the drive gear 210, and the drive gear 210 and the winding wheel body 220 are coaxially arranged, that is, the drive gear 210 can drive the winding wheel body 220 to rotate synchronously. Along the outer side of the winding wheel body 220, starting from the side closest to the drive gear 210, a plurality of wire rope grooves 221 are provided. The beginning and end of each wire rope groove 221 are connected to the end of the adjacent wire rope groove 221, and all the wire rope grooves 221 are spiral in shape. The body 220 of the winding wheel is provided with a cavity 230 inside, and a winding wheel shaft 240 extending from the drive gear 210 is provided in the cavity 230. A winding wheel magnet 250 is provided in the cavity.

[0031] In a preferred embodiment of this application, the cavity is cylindrical in shape, and the winding wheel shaft 240 is disposed at the center of the cylindrical cavity. The winding wheel shaft 240 includes a winding wheel shaft base 241 and a winding wheel shaft main shaft 242. The winding wheel shaft base 241 is a cylinder extending from the drive gear 210, and the winding wheel shaft main shaft 242 is disposed at the end of the winding wheel shaft base 241 away from the drive gear 210. The winding wheel shaft base 241 and the winding wheel shaft main shaft 242 are integrally formed. n reinforcing ribs 260 are disposed between the winding wheel shaft base 241 and the winding wheel body 220, dividing the cavity into n equal sub-cavities, where n ≥ 2. By adding reinforcing ribs 260, the structural strength of the surface of the winding wheel body 220 is enhanced, thereby strengthening the support of the winding wheel body 220 for the wire rope 400 and allowing the clothes rack to bear more clothes. Theoretically, more reinforcing ribs 260 result in stronger support for the winding wheel body 220, but this also increases the overall weight of the winding wheel and the processing difficulty of the winding wheel body. In this embodiment, the reinforcing ribs 260 can be set to 3, 4, 6, or 8, correspondingly dividing the cavity into 3, 4, 6, or 8 sub-cavities. In the preferred embodiment provided by this application, the reinforcing ribs 260 are set to 6, which provides sufficient support for the winding wheel body 220 while keeping the processing difficulty and efficiency within an acceptable range.

[0032] When the cavity 230 is divided into multiple sub-cavities by the reinforcing rib 260, the winding wheel magnet disposed in the cavity needs to be divided into multiple sub-winding wheel magnets so that they can be disposed in the sub-cavities respectively. Therefore, m sub-winding wheel magnets are disposed, each of which is disposed in one sub-cavity, where 2≦m≤n. When there are 6 sub-cavities, this embodiment of the application can be configured with 6 sub-winding wheel magnets, each of which is disposed in one sub-cavity. In a preferred embodiment of this application, four sub-winding wheel magnets are provided, and the sub-cavities are sequentially designated as a first sub-cavity 231, a second sub-cavity 232, a third sub-cavity 233, a fourth sub-cavity 234, a fifth sub-cavity 235, and a sixth sub-cavity 236. The first sub-winding wheel magnet 251 is disposed in the first sub-cavity 231, the second sub-winding wheel magnet 252 is disposed in the second sub-cavity 232, the third sub-winding wheel magnet 253 is disposed in the fourth sub-cavity 234, and the fourth sub-winding wheel magnet 254 is disposed in the fifth sub-cavity 235. The sub-winding wheel magnets can be glued to the sub-cavities or fixed in place by snap-fitting; these are mature technologies achievable in the prior art and will not be elaborated upon here. By installing sub-winding wheel magnets in the first sub-cavity 231, the second sub-cavity 232, the fourth sub-cavity 234, and the fifth sub-cavity 235, with each pair of sub-winding wheel magnets arranged adjacently as a group and each group separated by a sub-cavity, the design ensures that most of the space in the winding wheel body is filled with a magnetic field. This provides magnetic attraction to the portion of the wire rope wound around the winding wheel body. Within the spaced sub-cavities, a certain area of ​​magnetic field weakening is formed, resulting in overall magnetic field non-uniformity. This creates a weak force area between the wire rope and the winding wheel body when the wire rope is wound in the wire rope groove, which facilitates smoother wire rope extraction.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
