Description

Technical Field

[0001] This utility model relates to a wire rope drive device for a clothes drying rack, and more particularly to an anti-tangling wire rope drive device. Background Technology

[0002] The wire rope drive device mainly consists of core components such as a motor, a strand reel, and a wire pressing assembly. Its design purpose is to achieve smooth and reliable lifting and lowering of the drying rack.

[0003] In this drive unit, a spiral groove is carefully designed on the strand reel. This unique design allows the wire rope to be tightly and orderly wound around the spiral groove in a predetermined sequence. This orderly winding is crucial for ensuring that the wire rope maintains a stable and uniform tension distribution during the stress process, thereby ensuring the smoothness of the raising and lowering process of the drying rack.

[0004] The wire clamping assembly plays a crucial role in this process. Its main function is to apply appropriate pressure to the steel wire rope wound on the strand reel, firmly pressing the wire rope into the groove and preventing it from loosening or shifting during operation. By precisely controlling the pressure, the wire clamping assembly ensures that the steel wire rope always fits tightly against the spiral groove, maintaining a good winding state. This ensures that the steel wire rope transmits power efficiently and stably, providing a reliable guarantee for the smooth raising and lowering of the drying rack.

[0005] However, if the wire clamping assembly malfunctions or is improperly adjusted, problems such as wire rope skipping and tangling can occur. Once the wire rope skips or becomes tangled, it directly disrupts the original force balance of the wire rope, causing it to bear uneven tension during operation. This not only accelerates the wear of the wire rope and reduces its service life, but more seriously, it can directly cause obstacles in raising and lowering the clothes drying rack, such as jamming, inability to raise or lower normally, or unstable raising and lowering speed, severely affecting the normal use of the entire clothes drying equipment. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a guide component and a wire rope drive device for guiding the synchronous movement of wire rope, which can avoid problems such as wire rope skipping and repeated winding.

A guide post is arranged parallel to the threaded post to guide the threading block to move along the threaded post; The ratio of the number of teeth of the first gear and the second gear is the same as the ratio of the pitch of the spiral groove of the winding portion and the threaded column.

[0008] A further preferred embodiment of this utility model is as follows: the ratio of the number of teeth of the first gear and the second gear is 4:1; the ratio of the pitch of the spiral groove of the winding part to the pitch of the threaded column is 4:1.

The bottom surface of the upper connecting part and the top surface of the lower connecting part are in close contact, so that the first semicircular hole and the second semicircular hole form the threading hole.

[0010] A further preferred embodiment of this utility model is: the threading part is provided with a guide part, and the guide part is provided with two guide ears; The guide post is provided with a guide cavity into which the guide part extends, and a guide groove that mates with the guide ear.

[0011] A further preferred embodiment of this utility model is: a base supported on the housing of a clothes drying rack; the lower end of the threaded column is connected to a first side of the base; and the lower end of the guide column is connected to a second side of the base.

[0012] Another preferred subject: a guiding assembly, comprising a second gear meshing with a first gear of a clothes dryer reel, a threaded post integrally connected to the second gear, and a threading block, the threading block having a threaded hole fitted on the threaded post, and the threading block having a threading hole through which the steel wire rope of the clothes dryer passes; A guide post is arranged parallel to the threaded post to guide the threading block to move along the threaded post; The ratio of the number of teeth of the first gear and the second gear is a, and the ratio of the spiral groove of the winding part of the clothes drying machine coil to the pitch on the threaded column is a', where a is equal to a'.

[0013] A further preferred embodiment of this utility model is as follows: the ratio of the number of teeth of the first gear and the second gear is 4:1; the ratio of the pitch of the spiral groove of the winding part to the pitch of the threaded column is 4:1.

[0014] A further preferred technical solution of this utility model is: the threading block is composed of two connected parts, the first part includes a columnar body with a threaded hole and an upper connecting part located on one side of the columnar body, and the bottom surface of the upper connecting part has a first semi-circular hole; The second part includes a lower connecting portion, the top surface of which has a second semi-circular hole; When the upper connecting part and the lower connecting part are fixedly connected by screws, they form a threading part.

[0017] Compared with existing technologies, the advantages of this invention are: This technical solution ensures highly synchronized operation between the strand reel and the guide assembly by specifically setting the tooth ratio of the first and second gears, and the pitch ratio of the spiral groove to the threaded column in the winding section. This ensures that the moving speed of the threading block on the threaded column is completely consistent with the winding speed of the wire rope in the spiral groove. This highly synchronized operation mechanism effectively avoids problems such as skipped wires, repeated winding, or uneven winding that may occur during the winding process, significantly improving the service life of the wire rope and the overall operating efficiency of the clothes drying rack.

The threading block is fitted onto the threaded post through the threaded holes and moves smoothly along the threaded post under the guidance of the guide post. This not only ensures that the wire rope stays on the correct path during winding, but also further enhances the stability of the wire rope through the cooperation of the guide post and the threading block. The guide cavity and guide groove on the guide post fit tightly with the guide part and guide ear on the threading block, ensuring that the threading block does not deviate or wobble during movement. This effectively solves the common problems of wire rope skipping and repeated winding in traditional wire rope drive devices, significantly improving the operational stability and reliability of the clothes drying rack.

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0023] like Figures 1 to 3As shown, an anti-tangling wire rope drive device 100 includes a housing 10, a motor 20, and two meshing stranding reels 30. The motor 20 drives the stranding reels 30 to rotate, and the stranding reels 30 are used to wind the wire rope s. The motor 20, as the power core of the entire drive device, primarily provides stable and continuous power support for the rotation of the stranding reels 30, ensuring that the stranding reels 30 can rotate precisely according to a preset running trajectory and speed. The stranding reels 30 are the key component for winding the wire rope s, allowing the wire rope s to be tightly and orderly wound on them, thus providing reliable physical support and power transmission for the lifting and lowering operation of the clothes drying rack.

[0024] To further enhance the operational stability and reliability of the device, each strand reel 30 is equipped with a specially configured guide assembly 40. The main function of the guide assembly 40 is to guide the winding and movement of the wire rope s on the strand reel 30, ensuring that the wire rope s maintains a stable and uniform tension distribution during the stress process, in order to solve problems such as wire rope tangling or skipping.

[0025] Specifically, the twisted wire reel 30 consists of two key parts: first, a first gear 31 connected to the motor 20 and capable of rotating synchronously, which ensures the power transmission of the twisted wire reel 30; second, a winding section 32, whose surface is distributed with spiral grooves 33. This unique spiral groove structure can guide the steel wire rope s to be tightly and orderly wound on the winding section 32 along a predetermined path, thereby effectively avoiding problems such as loosening, twisting or cross-entanglement that may occur during the winding process of the steel wire rope s, providing a solid foundation for the smooth lifting and lowering of the clothes drying rack.

[0026] The guide assembly 40, which closely mates with the stranded wire reel 30, also plays a crucial role. For example... Figures 4 to 5 As shown, the guide assembly 40 mainly includes the following core components: a second gear 41 that meshes with the first gear 31, which ensures that the guide assembly 40 and the stranding reel 30 operate synchronously; a threaded post 42 integrally connected to the second gear 41, which provides stable support and a precise movement path for the wire guide block 43; and the wire guide block 43 itself, which is fitted onto the threaded post 42 through a threaded hole 44 and has a wire guide hole 45 on it, through which the wire rope s is guided to the spiral groove 33 of the stranding reel 30 for winding.

[0027] In addition, to further ensure that the wire threading block 43 can move smoothly and accurately along the threaded post 42, a guide post 50 parallel to the threaded post 42 is specially set. It can effectively position the movement direction of the wire threading block 43 and prevent it from deviating or shaking during the movement, thereby ensuring that the winding process of the wire rope s is smoother and more precise.

[0028] In its design, the gear ratio between the first gear 31 and the second gear 41 is precisely set to 'a', while the pitch ratio between the spiral groove 33 of the winding section 32 and the threaded post 42 is set to 'a', with 'a' and 'a' having identical values. This carefully predetermined consistency between the gear ratio and the pitch ratio ensures perfect synchronous operation between the stranding disc 30 and the guide assembly 40. When the motor 20 drives the first gear 31 to rotate, the second gear 41, through the precise gear ratio transmission, drives the threaded post 42 to rotate at a corresponding speed. This causes the threading block 43 to move smoothly along the threaded post 42 and the guide post 50, ensuring that the wire rope s is always wound along the predetermined spiral groove 33 path. This effectively avoids problems such as skipped wires, repeated winding, or uneven winding that may occur during the winding process, greatly improving the service life of the wire rope s and the overall operating efficiency of the clothes drying rack.

[0029] In this invention, the gear ratio of the first gear 31 to the second gear 41 is preferably set to 4:1, and the pitch ratio of the spiral groove 33 of the winding section 32 to the threaded post 42 is also set to 4:1. This precise parameter matching enables highly synchronized operation between the stranding reel 30 and the guide assembly 40. Specifically, when the motor 20 drives the first gear 31 to rotate, the second gear 41 can drive the threaded post 42 to rotate at a corresponding speed due to the 4:1 gear ratio. At the same time, the pitch ratio of the spiral groove 33 of the winding section 32 to the threaded post 42 is also 4:1, which means that the moving speed of the threading block 43 on the threaded post 42 is perfectly matched with the winding speed of the wire rope s in the spiral groove 33. This highly synchronized operation mechanism ensures that the wire rope s maintains a stable and uniform tension distribution during winding, effectively avoiding problems such as skipped wires, repeated winding, or uneven winding that may occur during winding.

[0030] It should also be noted that the wire threading block 43 consists of two parts, which are fixedly connected by screws to form a complete wire threading part g, which is used to guide the wire rope s through.

[0031] The first part is a cylindrical body d1, whose core feature is a precisely machined threaded hole 44. This threaded hole 44 fits perfectly with the threaded post 42, ensuring that the threaded block 43 can move smoothly and accurately along the threaded post 42. On one side of the cylindrical body d1, an upper connecting part d2 extends, and its bottom surface has a first semi-circular hole c1. The shape and size of this semi-circular hole c1 are precisely calculated to ensure a perfect fit with the lower connecting part d3 of the second part.

[0032] The second part is the lower connecting part d3, whose top surface has a second semi-circular hole c2. When the upper connecting part d2 and the lower connecting part d3 are fixedly connected by screws, the two semi-circular holes c1 and c2 will fit tightly together to form a complete wire-passing hole 44. The diameter and shape of this wire-passing hole 44 are carefully designed to ensure that the wire rope s can pass through smoothly, while remaining stable during operation and avoiding any unnecessary friction or wear.

[0033] This split-type design of the threading block 43 not only improves assembly flexibility but also enhances its durability in practical use. By dividing the threading block 43 into two parts, the size and shape of each part can be more precisely controlled during processing, thereby ensuring that the final assembled threading hole 44 has extremely high precision and consistency.

[0034] During the assembly process, such as Figure 8 As shown, the wire rope s can be first placed into the first semicircular hole c1 of one of the connecting parts (e.g., the upper connecting part d2), and then the other connecting part (the lower connecting part d3) can be placed on top to ensure that the two semicircular holes (the first semicircular hole c1 and the second semicircular hole c2) are precisely aligned, thereby completing the assembly of the wire threading block 43. This assembly method is not only simple to operate, but also effectively ensures the stability and accuracy of the wire rope s within the wire threading hole 44, further improving the operational reliability of the entire drive device.

[0035] In addition, such as Figure 6 and Figure 7 , Figure 8 As shown, a guide section g1 is specially designed in the structural design of the threading part g. This technical means plays a key role in ensuring the stable movement of the threading block 43. The guide section g1 is equipped with two guide ears g2. These two guide ears g2 not only enhance the structural stability of the guide section g1, but also provide additional support points for the precise movement of the threading block 43. The guide post 50 that cooperates with it is provided with a special guide cavity 51. Its size and shape are perfectly matched with the guide section g1, so that the guide section g1 can be smoothly inserted into it. Moreover, the guide post 50 is also provided with guide grooves 52 that cooperate with the guide ears g2. These guide grooves 52 provide a clear path for the movement of the threading block 43, ensuring that it always maintains a stable and straight movement trajectory when moving on the threaded post 42, thereby effectively avoiding problems such as wire rope tangling and confusion caused by movement deviation.

[0036] Furthermore, the stability of the entire drive unit also relies on a specifically designed base 60. The base 60 is firmly supported on the clothes dryer's housing, providing a solid foundation for the entire device. The lower end of the threaded post 42 is connected to the first side of the base 60 via a precise mechanical connection. This connection not only ensures the stability of the threaded post 42 but also allows it to rotate smoothly under motor drive. Similarly, the lower end of the guide post 50 is connected to the second side of the base 60. This arrangement allows the guide post 50 to remain parallel and stable with the threaded post 42, further enhancing the structural stability of the entire guide assembly 40.
