Description

Technical Field

[0001] This utility model relates to the field of electric clothes drying rack technology, and in particular to an electric clothes drying rack pull cord fine adjustment structure and an electric clothes drying rack with the fine adjustment structure. Background Technology

[0002] Electric clothes drying racks are quite common, offering convenience for people to dry their clothes automatically. Their structure generally consists of a fixed mechanism and a lifting mechanism. The fixed mechanism is connected to the ceiling and mainly includes the main unit base and drive components (i.e., the motor). The lifting mechanism mainly includes the lifting frame and the clothes drying rod. The drive component in the fixed mechanism is connected to the lifting frame via steel cables to achieve the lifting action.

[0003] When the lifting mechanism is raised and integrated with the fixing mechanism (i.e., in the retracted state), the lifting frame needs to maintain a tight fit with the main unit to achieve a good aesthetic effect.

[0004] However, the lifting beams at both ends of the lifting frame are synchronously connected to the drive end of the drive component via two steel wires (also called tension wires). During use, the lifting frame needs to maintain a horizontal lifting motion. After a period of use or under uneven stress, the four steel wires may not remain completely of the same length, causing the lifting frame to tilt and lose its horizontal position.

[0005] In other words, the lengths of the four steel wires will change, resulting in inconsistencies in length. This ultimately prevents the lifting frame from lifting horizontally, causing a noticeable tilt.

[0006] Furthermore, when the lifting frame is raised to its highest position, it cannot guarantee a tight fit with the main unit. The height of the four corners of the lifting frame is inconsistent, and the gaps are very obvious, which greatly affects the appearance and makes the product look cheap and flawed.

[0007] In addition, because the four steel wires are of different lengths, the force on the drive component (i.e., the motor) will also be uneven, which will eventually affect the normal operation of the motor. Therefore, the failure rate of existing electric clothes drying racks has remained high. Utility Model Content

[0008] The purpose of this invention is to provide a fine-tuning structure for the pull cord of an electric clothes drying rack. This structure can be directly applied without altering the existing lifting beam, significantly reducing upgrade and modification costs. It also allows for adjustment of the steel wire (pull cord) length, ensuring the lifting frame remains horizontal and greatly facilitating maintenance. Furthermore, this invention provides an electric clothes drying rack with this fine-tuning structure, ensuring a tight fit between the lifting frame and the main unit after the frame is fully raised, thus maintaining the overall aesthetic appeal of the product.

[0009] To solve the above-mentioned technical problems, this utility model provides, in one aspect, a fine-tuning structure for the pull cord of an electric clothes drying rack, including...

[0010] A connecting seat is connected to the side of the lifting beam, and the connecting seat is provided with a transverse bend extending toward the lifting beam, and the transverse bend is provided with a connecting hole.

[0011] A connector is threaded to the connecting hole, and one side of the connector is provided with a groove running through its axial direction.

[0012] As a further improvement of this utility model, the connecting hole faces the inner cavity of the lifting beam.

[0013] As a further improvement of this utility model, the connecting seat is provided with at least one fixing hole facing the direction of the lifting beam.

[0014] As a further improvement of this utility model, the lifting beam is provided with a second fixing hole corresponding to the first fixing hole.

[0015] On the other hand, an electric clothes drying rack is also provided, including a main unit base fixed to the ceiling, a drive motor is provided in the main unit base, and a plurality of steel wires are provided at the drive end of the drive motor.

[0016] The end of the steel wire passes through the groove of the connector and is limited and connected to the connector by the end limiting block.

[0017] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0018] This invention can be directly applied to existing crossbeams without requiring modifications to existing molds, processing equipment, etc., which can significantly reduce product upgrade costs.

[0019] The connecting seat and connecting parts are easy to process and low in cost, and are simple to install. They can be fastened to the original crossbeam using bolts or screws, making operation convenient. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 9The present invention will be further described in detail with reference to embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0037] Before proceeding, it is necessary to provide a more detailed explanation of the drawbacks of the existing products so that they can produce a sufficiently significant difference from the technical effects of this application.

[0038] The traditional connection method is:

[0039] The steel wire is connected to the crossbeam at a fixed length; that is, the steel wire is pre-cut to a specific length, and then its two ends are fixed to the drive end of the drive motor and the crossbeam, respectively. Because it is difficult to guarantee absolute uniformity in the cutting dimensions, the length of the steel wire is inconsistent from the initial stage. Furthermore, over time, factors such as the stress and deformation of various linkage components and initial installation errors cause the steel wire to gradually lengthen and deform. This stress and deformation of the linkage components eventually leads to a noticeable tilt in the lifting frame, making it impossible to maintain a level position. When fully retracted, obvious gaps will appear.

[0040] The traditional maintenance method involves professional personnel disassembling the machine on-site and replacing the steel wire or other parts. This process involves many factors, such as maintenance costs, on-site service time, disassembly and assembly tools, climbing tools, types of parts, and time cycle, all of which can restrict normal use by users. Therefore, the traditional maintenance method is very inconvenient and results in a poor user experience.

[0041] The present invention will now be described in detail: Example 1

[0042] The purpose of this embodiment is to provide a fine-tuning structure for the pull cord of an electric clothes drying rack, including a connecting seat 200, which is a sheet-like structure that is attached to the side of the lifting crossbeam 100. The two can be fixed by welding, riveting, or fastening, as long as a good fixing effect is achieved. Furthermore, the side can be a left-right side as shown in the figure, a top-bottom side, or the inner or outer side of the profile. Of course, the connection position should be as close as possible to both ends of the lifting crossbeam 100 to improve the overall stability when hanging items and prevent tilting. Alternatively, the connecting seat 200 can also be connected to the side of the lifting longitudinal beam. Whether it is the lifting crossbeam or the lifting longitudinal beam, it is connected to the lifting frame to achieve the lifting action.

[0043] The connecting seat 200 has a transversely bent portion 202 extending towards the lifting beam 100. With this structure, the overall shape of the connecting seat 200 is a right-angled L-shape, which can fit snugly against the corners of the lifting beam, resulting in a more stable connection. The transversely bent portion 202 has a connecting hole 2021 facing the inner cavity 102 of the lifting beam 100, facilitating the deep tightening of bolts or screws. Of course, the connecting hole 2021 can be a through hole or a blind hole, with a certain depth.

[0044] In addition, it also includes a connector 300, which is threaded to the connecting hole 2021, and a groove 301 extending through its axial direction is provided on one side of the connector 300. Specifically, the threading method can be that the connector uses external threads to connect with the internal threads of the connecting hole, or the connector uses internal threads to connect with the external threads of the connecting hole.

[0045] In other words, the connector 300 can rotate up or down within the connecting hole 2021, thereby changing its own height. Furthermore, one side of the connector 300 has a groove 301 extending through its axial direction; this groove 301 is used to hold the steel wire 500. The steel wire 500 does not rotate within the groove 301, leaving a gap between them.

[0046] This structure is completely different from traditional connection methods. This improvement allows for fine-tuning of the height of the connector 300 by raising or lowering it, thereby adjusting the length of the connected steel wire 500. Because the length of the steel wire 500 may change slightly after prolonged use, the fine-tuning of the connector 300's height can accommodate these changes, thus enabling adjustment of the length of each steel wire 500 and ensuring a horizontal lifting state.

[0047] Of course, the longer the axial length of the connector 300, the greater the stroke for raising or lowering, and the larger the range of fine adjustment. Conversely, the smaller the stroke, the smaller the range of fine adjustment. The specific axial length of the connector 300 can be determined according to actual needs.

[0048] To facilitate quick installation, the connecting seat 200 is provided with at least one (in practice, two are provided, symmetrically arranged at both ends) fixing hole 201 facing the lifting beam 100. Furthermore, the lifting beam 100 is provided with a second fixing hole 101 corresponding to the first fixing hole 201.

[0049] Once the two types of holes align, the connection can be secured using fasteners such as bolts, rivets, or anchors, making the operation convenient. Alternatively, holes can be drilled directly on-site or rivets can be used without pre-drilling. However, this method requires workers to accurately locate the installation position and is suitable for softer profiles such as aluminum. Any deviation in position will also affect the length of the 500mm steel wire.

[0050] It should also be noted that, as Figure 8 what Figure 9 The structure shown depicts the connecting seat 200 positioned inside the lifting beam 100. As can be seen in the figure, the two can be connected via the fastener 8. Alternatively, they can be fastened, welded, or riveted. Because the outer surface of the lifting beam 100 is smooth and aesthetically pleasing, placing the connecting seat 200 on its exterior facilitates installation, but it also somewhat affects the appearance. Conversely, placing the connecting seat 200 inside the beam improves the appearance, but its shape must be compatible with the inner cavity of the lifting beam 100.

[0051] The advantage of placing the fastener 8 inside the lifting beam 100 is its better concealment and more aesthetically pleasing overall appearance. Although the shape of the fastener 8 has changed, the core technical features remain, such as the connecting seat 200, the transverse bending portion 202, the connecting hole 2021, and the connecting piece 300. The change in its overall shape is to better fit into and adapt to the inner cavity of the lifting beam 100; therefore, the appropriate change in shape does not deviate from this technical solution. Example 2

[0052] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0053] Reference image Figures 5 to 7 The invention also provides an electric clothes drying rack, including a main unit base 400 fixed to the ceiling via expansion joints. The main unit base 400 houses a drive motor 401, and the drive end of the drive motor 401 has four steel wires 500. In practice, every two steel wires 500 form a group, with the two groups mirror-image each other and arranged in opposite directions, representing a conventional connection structure.

[0054] The end of the steel wire 500 passes through the groove 301 of the connector 300 to achieve an embedded connection, and is limited and connected to the connector 300 by the end limiting block 501. The limiting block 501 is large in volume and will not pass through the groove 301, thus playing a limiting and supporting role.

[0055] With the above improvements, users can easily control the tightening of each connector, ensuring the tension of the steel wire. This allows the lifting frame to rise and fall smoothly in a horizontal position. When fully retracted, it fits perfectly and seamlessly with the main unit, making the product more aesthetically pleasing. Traditional maintenance methods, such as professional on-site disassembly and maintenance, are costly, cumbersome, and inconvenient, affecting the normal use of the product.

[0056] This invention can be directly applied to existing crossbeams without requiring modifications to existing molds, processing equipment, etc., which can significantly reduce product upgrade costs.

[0057] The connecting seat and connecting parts are easy to process and low in cost, and are simple to install. They can be fastened to the original crossbeam using bolts or screws, making operation convenient.

[0058] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
