Description

Technical Field

[0001] This utility model relates to the field of clothes drying equipment technology, and in particular to a winding wheel for winding steel wire ropes when raising and lowering clothes drying racks, a winding device using the winding wheel, 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 a groove 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 out of the groove, 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 reel to become loose. When the clothes rack rises or falls, the loose steel wire rope will rub against the gearbox housing, making it prone to jumping out of the groove. Utility Model Content

[0005] This application provides a winding wheel for steel wire rope, which allows the steel wire rope wound on the winding wheel to fit tightly against the steel wire rope groove of the winding wheel, thereby solving the problem of the steel wire rope jumping out of the groove during the raising or lowering of the clothes rack.

[0006] The winding wheel for steel wire rope provided in this application embodiment includes a drive gear, a winding wheel body is provided on one side of the drive gear, a steel wire rope groove is provided along the outer side of the winding wheel body, a cavity is provided inside the winding wheel body, a winding wheel shaft extending from the drive gear is provided in the cavity, and a winding wheel magnet is provided in the cavity.

[0007] The wire rope winding reel provided in this application embodiment has a magnet installed in the cavity inside the reel body. The magnet exerts an attractive force on the wire rope, thereby overcoming the outward tension of the wire rope and causing the wire rope to press tightly against the wire rope groove in the reel body. This prevents the wire rope from jumping out of the groove when the reel rotates.

[0008] For the same purpose, embodiments of this application also provide a winding device, including a gearbox housing, a winding wheel mounting cavity provided 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, a winding wheel shaft bearing provided in the winding wheel mounting cavity, the aforementioned winding wheel for the wire rope being mounted on the winding wheel mounting cavity, and the winding wheel shaft being mounted on the winding wheel shaft bearing.

[0009] The winding device provided in this application mainly improves the winding wheel. A magnet is installed in the internal cavity of the winding wheel. The magnet exerts an attractive force on the wire rope, thereby overcoming the outward tension of the wire rope and causing the wire rope to press tightly against the wire rope groove of the winding wheel body. When the winding wheel rotates, because the wire rope is pressed tightly against the wire rope groove, the wire rope will rotate completely along the wire rope groove, thus solving the problem of wire rope jumping out of the groove and avoiding friction between the wire rope and the gearbox housing.

[0010] This application embodiment also provides a clothes drying machine, including a main unit and a clothes rack. The main unit is equipped with the above-mentioned winding device. Each winding wheel of the winding device is wound with a steel wire rope. The first end of the steel wire rope is fixed on the steel wire rope groove of the winding wheel close to the drive gear, and the second end of the steel wire rope is fixed on the clothes rack. The steel wire rope is wound on the winding wheel along the steel wire rope groove.

[0011] The clothes drying rack provided in this application embodiment improves upon its winding mechanism. When the winding wheel rotates, the magnet inside attracts the wire rope, overcoming its tension and causing the wire rope to press firmly against the groove on the winding wheel. As the winding wheel rotates, the wire rope, pressed against the groove, rotates completely along it, thus solving the problem of the wire rope jumping out of the groove and preventing friction between the wire rope and the gearbox housing.

Detailed Implementation

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Therefore, features specified with terms such as "first" or "symmetric" may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

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.

[0017] The technical solution of this application will now be described in detail with reference to the accompanying drawings.

[0018] The inventors of this application discovered during the repair of a clothes drying rack provided by the applicant that the wire rope sometimes jumps out of the grooves during the winding process, preventing it from fully matching the grooves. The inventors found that when there are clothes hanging on the clothes rack (i.e., when the clothes rack is under load), the wire rope winds around the grooves of the winding rack in an orderly manner. However, when the clothes rack is unloaded, the wire rope jumps out of the grooves. This jumping out of the grooves can affect the smooth winding of the wire rope, potentially preventing the clothes rack from retracting properly.

[0019] Further research by the inventors revealed that the main reason for the wire rope jumping out of its groove is that when there is no load on the clothes rack, the wire rope, under the action of elastic tension, will spread outward on the winding reel, causing the fit between the wire rope and the groove on the winding reel to loosen. When the clothes rack rises or falls, the loose wire rope is hindered by friction with the gearbox housing, easily leading to the wire rope jumping out of its groove.

[0020] Based on this, the inventors of this application provide an improved clothes drying rack to solve the aforementioned problems. For example... Figures 1 to 7As 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 wire rope jumping out of the groove caused by defects in the winding device 10 of existing clothes drying racks. The winding device 10 provided in the embodiments of 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 square-shaped 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 it is cylindrical in shape. The side wall of the winding wheel mounting cavity 110 is provided with a wire rope inlet and 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 focuses on improving its winding wheel 200. The winding wheel 200 provided in this application 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. The drive gear 210 and the winding wheel body 220 are coaxially arranged, meaning that the drive gear 210 can drive the winding wheel body 220 to rotate synchronously. Along the outer surface 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 spirally shaped. 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.

[0023] 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.

[0024] 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.

[0025] The winding device provided in this application also has a wire pressing module mounting position 130 in the gearbox housing corresponding to each winding wheel. 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.
