[0002] As a new generation of intelligent drying tools, clothes drying racks are being used by more and more families. To make them more convenient to use, existing clothes drying racks generally have a lift-up function (which is usually triggered by touch or physical action, such as lifting the drying rod and the clothes drying rack automatically rising).
[0003] For example, Chinese utility model patent publication number "CN221993800U" discloses "a lifting control system for a clothes drying rack and a clothes drying rack, including a power module, the power module including at least a pull rope, one end of which is connected to a drying rod for performing the lifting and lowering action of the drying rod; an air pressure detection module connected to the power module to collect the pressure signal of the drying rod in the direction of gravity; and a controller connected to the power module and the air pressure detection module to receive the pressure signal of the drying rod in the direction of gravity and control the lifting and lowering of the drying rod. This utility model collects the pressure signal of the drying rod in the direction of gravity through the air pressure detection module, simplifies the operation of controlling the lifting and lowering of the drying rod, provides users with a convenient and efficient clothes drying experience, and meets user needs."
[0004] The existing technology has the following problems: When the user uses the clothes drying rack's lifting function, the wire rope is momentarily in a free state. During this state, the wire rope is prone to tangling or getting caught in the scissor bracket or pole seat, causing the wire rope or scissor bracket to jam and damage the clothes drying rack. Furthermore, existing wire rope limiting devices for clothes drying racks lack a stable guiding device, making the wire rope prone to long-term wear and breakage. Therefore, a limiting device that can protect the wire rope and maintain its tension is needed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a wire rope limiting device that can reduce the wear of the wire rope through arc transition guidance and can also continuously tighten the wire rope.
[0006] This utility model provides a wire rope limiting device, comprising:
[0007] The main body has a motor assembly inside, and a steel wire rope is connected to the output shaft of the motor assembly. The steel wire rope extends to both sides of the main body and downwards.
[0008] The drying section has pole seats on both sides, which support and install the poles used for drying. The bottom of the steel wire ropes on both sides extends into the pole seats on both sides and is installed therewith.
[0009] A guide buckle is installed inside the rod base and includes a guide rail. The steel wire rope extends into the guide buckle and bends around the guide rail to a horizontal state.
[0010] An elastic element is installed inside the rod seat. The elastic element is installed with the horizontal steel wire rope to keep the steel wire rope taut at all times through elastic force.
[0011] As a further improvement of this utility model, a scissor frame is provided between the main body and the rod seat, and the steel wire rope is installed by passing through the scissor frame;
[0012] The top of the rod holder is open and has a rod holder cavity, and the bottom of the scissor bracket extends into the rod holder cavity and is installed therewith;
[0013] The rod base, the scissor bracket, and the guide buckle are installed via a pin.
[0014] As a further improvement of this utility model, the guide buckle includes a connecting plate, the top of which has a rope hole, through which the steel wire rope passes to pierce the connecting plate.
[0015] As a further improvement of this utility model, an extension plate is provided on one side of the connecting plate, and a transition block is installed on the extension plate.
[0016] The transition block is arranged in an arc shape at one end facing the connecting plate, and the wire rope is bent around the arc-shaped end.
[0017] As a further improvement of this utility model, the bottom surface of the transition block is provided with a concave bottom arc surface, and the wire rope is installed in close contact with the bottom arc surface.
[0018] As a further improvement of this utility model, a protruding mounting post is installed on the extension hanging piece, and a mounting hole corresponding to the mounting post is provided on the transition block, and the mounting post and the mounting hole are installed together.
[0019] As a further improvement of this utility model, the bottom of the extension hanging piece is bent and provided with a support piece, the support piece is horizontally arranged, and the support piece supports the transition block and the wire rope.
[0020] As a further improvement of this utility model, a fixing frame is installed at each of the two ends of the pole seat cavity, and an installation arm is provided at the end of the two fixing frames that are far apart from each other. The installation arm extends out of the pole seat cavity and installs the drying pole.
[0021] As a further improvement of this utility model, a plug is installed at the bottom end of the wire rope.
[0022] As a further improvement of this utility model, the elastic element includes a limiting spring, one end of which is installed with the fixing frame, and the other end of which is installed with the plug.
[0023] Compared to existing technologies, the advantages of this invention are as follows: This solution incorporates a guide buckle structure for changing the direction of the wire rope. After the wire rope is bent to a horizontal position, a spring is installed to tighten it. This spring consistently provides a taut force, ensuring that the free state of the wire rope during the lifting function is immediately tightened and straightened by the spring, preventing it from getting stuck in other components and damaging the clothes dryer. Furthermore, the guide buckle integrates an arc-shaped guide limit block, which provides an arc transition and protective limit for the wire rope, reducing wear caused by the extension and retraction of the wire rope.

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0036] Specific Implementation Example 1: Please refer to Figures 1-9 A wire rope limiting device includes:
[0037] The main body 21 has a motor assembly inside, and a steel wire rope 25 is connected to the output shaft of the motor assembly. The steel wire rope 25 extends to the outside and downward from the inside of the main body 21 to both sides.
[0038] It is understandable that the above-mentioned motor assembly includes conventional servo motors and winding reels in clothes drying racks. The output shaft of the motor directly controls the rotation of the winding reel, and a steel wire rope 25 is wound on the winding reel. Therefore, the forward and reverse rotation of the motor can reel in and out the steel wire rope 25, thereby controlling the lifting and lowering movement of the drying rod.
[0039] The drying section has pole seats 23 on both sides. The pole seats 23 on both sides support and install the poles used for drying. The bottom of the steel wire ropes 25 on both sides extends into the pole seats 23 on both sides and is installed therewith.
[0040] It is understood that the aforementioned drying section includes a drying rod consisting of a drying rod 22 and a rod base 23. The drying rod 22 is a conventional drying rod with hanging holes for hanging clothes to dry, while the rod base 23 is used to fix the two drying rods 22 and connect to the main body 21.
[0041] A guide buckle is installed inside the rod base 23 and includes a guide rail. The steel wire rope 25 extends into the guide buckle and bends around the guide rail to a horizontal state. An elastic element is installed inside the rod base 23 and is installed with the horizontal steel wire rope 25 to keep the steel wire rope 25 taut at all times through elastic force.
[0042] It is understandable that the aforementioned guide buckle is used to: when the wire rope 25 is inserted into the pole seat 23 for installation, instead of directly connecting the wire rope 25 to the guide buckle in the conventional way, the wire rope 25 is bent to a horizontal state by 90 degrees through a guide rail and connected to an elastic element, so that the wire rope 25 is continuously tightened by the elastic force of the elastic element.
[0043] It should be further explained that when the user uses the lifting function or manually pushes the pole seat 23 on either side to lift, the steel wire rope 25 on the same side will become loose or unrestrained due to the loss of the downward pressure of the pole seat 23. This can easily cause the steel wire rope 25 to get stuck in the scissor frame 24 or other gaps, resulting in jamming or breakage. Therefore, when the steel wire rope 25 is in an unrestrained state, the limit spring 34 will tighten the steel wire rope 25 in real time through elastic tension, so that the steel wire rope 25 is always kept taut, which plays a role in protecting the steel wire rope 25 and other clothes drying rack components.
[0044] It's worth noting that the clothes drying rack's lift-up function means that by gently lifting a part of the clothes rack (usually the left or right end of the drying rod), the sensors inside the drying rack will detect the movement and automatically control the motor to start the lifting mode, eliminating the need to operate it via remote control or app each time. This design not only makes it more convenient for users but also reduces operating steps and improves the user experience.
[0045] A scissor frame 24 is provided between the main body 21 and the rod base 23, and the steel wire rope 25 is installed by passing through the scissor frame 24; the top of the rod base 23 is provided with a rod base cavity 38, and the bottom of the scissor frame 24 extends into the rod base cavity 38 and is installed therewith; the rod base 23, the scissor frame 24 and the guide buckle are installed by a pin.
[0046] It is understandable that the aforementioned scissor bracket 24 is a conventional structure for clothes drying racks, generally consisting of multiple connecting rods hinged together to form a multi-link structure. Its telescopic nature provides stability to the drying rod 22 as it approaches or moves away from the main body 21. The bottom of the scissor bracket 24 extends into the rod seat cavity 38, and a pin hole 37 is provided at the bottom of the connecting hanging piece 26. A pin passes through the pin hole 37 and the bottom of the scissor bracket 24 to connect the connecting hanging piece 26 and the rod seat 23.
[0047] The guide buckle includes a connecting plate 26, and the top of the connecting plate 26 has a rope hole 36, through which the steel wire rope 25 passes to the connecting plate 26.
[0048] It is understandable that the above-mentioned rope hole 36 is an opening through which the wire rope 25 can pass, and both the wire rope 25 and the plug 33 can extend vertically from the rope hole 36 to below the connecting hanger 26.
[0049] An extension plate 27 is provided on one side of the connecting plate 26, and a transition block 30 is installed on the extension plate 27; the end of the transition block 30 facing the connecting plate 26 is arc-shaped, and the wire rope 25 is bent around the arc-shaped end.
[0050] It is understood that the aforementioned extension plate 27 is an extension of the connecting plate 26, and the two are an integral structure. Furthermore, a guide transition block 30 is installed on the extension plate 27. The end face of the transition block 30 facing the connecting plate 26 is set with a semi-circular head, and this semi-circular head is located directly below the rope hole 36. Therefore, after the wire rope 25 extends into the area below the rope hole 36, it can directly bend to a horizontal state by transitioning around the semi-circular head arc.
[0051] The bottom surface of the transition block 30 is provided with a concave bottom arc surface 32, and the steel wire rope 25 is fitted and installed in close contact with the bottom arc surface 32. A protruding mounting post 29 is installed on the extension hanging piece 27, and the transition block 30 is provided with a mounting hole 31 corresponding to the mounting post 29. The mounting post 29 and the mounting hole 31 are installed together.
[0052] The bottom of the extension hanging piece 27 is bent to provide a support piece 28. The support piece 28 is horizontally positioned and supports the transition block 30 and the wire rope 25.
[0053] It is understood that the mounting post 29 on the aforementioned extension bracket 27 is correspondingly installed with the mounting hole 31 on the transition block 30 to fix the transition block 30 within the extension bracket 27. Regarding the fixing of the transition block 30, the vertical end face of the extension bracket 27 can mate with the wall surface of the rod seat cavity 38 to fix the transition block 30. And as... Figure 4 As shown, the extension bracket 27 has a horizontal bend at the top and a bent support plate 28 at the bottom, which can limit the transition block 30 from the top and bottom, and support the wire rope 25 and the transition block 30 through the support plate 28. Regarding the guidance and storage of the wire rope 25, as... Figure 5 As shown, the bottom surface of the transition block 30 is provided with an arc-shaped bottom arc surface 32, which can better surround and protect the wire rope 25, prevent the wire rope 25 from coming off and wearing out during the extension and contraction process, and further improve the extension and contraction stability of the wire rope 25.
[0054] Fixing brackets 35 are respectively installed at both ends of the pole seat cavity 38. An installation arm 39 is provided at the end of the two fixing brackets 35 that are far apart from each other. The installation arm 39 extends out of the pole seat cavity 38 and installs the drying pole.
[0055] It is understandable that the aforementioned fixing bracket 35 is a conventional connecting seat structure found in clothes drying racks, such as... Figure 2 As shown, the mounting arm 39 can extend out of the pole seat cavity 38 to connect and fix the drying rod 22.
[0056] A plug 33 is installed at the bottom end of the wire rope 25.
[0057] It is understandable that the aforementioned plug 33 is a conventional dropper structure in a clothes drying machine. Since the steel wire rope 25 needs to be connected to various components such as the connecting hanging plate 26, the diameter of the plug 33 is larger than the diameter of the steel wire rope 25 to prevent the steel wire rope 25 from falling off in the opposite direction.
[0058] The elastic element includes a limiting spring 34, one end of which is installed with the fixing frame 35, and the other end of which is installed with the plug 33.
[0059] It is understandable that the aforementioned limiting spring 34 is a tension spring. By setting the limiting spring 34, a traction force can always be provided to the plug 33, so that the wire rope 25 can be pulled and tightened by the limiting spring 34 at the moment of relaxation, making the connection state of the wire rope 25 more stable.
[0060] Working principle: The user can control the steel wire rope 25 to be relaxed at the top through the motor in the main unit 21. At this time, the drying rod 22 will slowly descend due to its own weight. The scissor frame 24 provides stability for the descent of the drying rod 22. When the drying rod 22 descends to a height that is convenient for the user to operate, the user can hang clothes on the drying rod 22.
[0061] like Figure 7 , Figure 8 As shown, when the user gently lifts the drying rod 22, manually lifting one side of the rod base 23 or one end of the drying rod 22 triggers the motor, causing the wire rope 25 to contract. At this time, the wire rope 25 on the lifted side is unrestrained and may get stuck in the scissor frame 24 or other positions within the rod base 23, causing jamming and damage to components such as the scissor frame 24 and the wire rope 25. Therefore, to solve this problem, a continuous pulling force from the limit spring 34 on the plug 33 ensures that the wire rope 25 is tightened when it becomes unrestrained. Furthermore, due to the installation of the transition block 30 and the guidance of the bottom arc surface 32, the tightening of the wire rope 25 is more stable.
[0062] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this application. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it is clear that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. Multiple units or devices recited in the apparatus claims may also be implemented by a single unit or device in software or hardware. The terms "first," "second," etc., are used to indicate names and do not indicate any particular order.
