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 lifting beam and an electric clothes drying rack with the beam. 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. 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 utility model is to provide a lifting beam for an electric clothes drying rack. It adopts a novel structural design, allowing for easy adjustment even when the steel wire lengths are inconsistent, ensuring the lifting frame remains horizontal and greatly simplifying maintenance. Furthermore, this electric clothes drying rack with this lifting beam ensures a tight fit between the lifting frame and the main unit when fully raised, guaranteeing the overall aesthetic appeal of the product.

[0009] To solve the above-mentioned technical problems, this utility model provides an electric clothes drying rack lifting beam, which includes a long strip-shaped profile body, and a support groove arranged along its length on one side of the profile body.

[0010] Also includes:

[0011] A connecting hole is provided on one side of the profile body and near both ends of the profile body;

[0012] A connector is threaded to the connecting hole, and one side of the connector is provided with a groove running through its axial direction.

[0013] As a further improvement of this utility model, the connecting hole is located near the support groove.

[0014] As a further improvement of this utility model, the profile body is provided with a reinforcing wall located between the connecting hole and the mounting groove, and the reinforcing wall extends through the axial direction of the profile body.

[0015] As a further improvement of this utility model, the profile body is provided with a stiffening plate located below the connecting hole and spaced apart from the connecting hole.

[0016] As a further improvement of this utility model, the two ends of the profile body are respectively provided with insertion cavities for holding corner brackets.

[0017] As a further improvement of this utility model, the end face of the profile body is square or round.

[0018] 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.

[0019] 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.

[0020] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0021] This invention improves the traditional crossbeam profile structure, completely changing the way it connects with the steel wire. While achieving a stable lifting connection, it also allows for fine-tuning of the steel wire length by rotating or lowering the connector, thereby ensuring consistent crossbeam height and levelness. It achieves the most stable and reliable effect through the simplest structure.

[0022] 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.

[0023] In addition, the above improvements have limited impact on the modification of profiles, but can significantly reduce the cost of upgrading and modifying existing products and processing costs, thereby enhancing the price advantage of the products. Attached Figure Description

[0041] 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 12 The 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.

[0042] 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.

[0043] The traditional connection method is:

[0044] 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.

[0045] 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.

[0046] The present invention will now be described in detail: Example 1

[0047] The purpose of this embodiment is to provide a lifting crossbeam for an electric clothes drying rack, which is further divided into lightweight crossbeams (such as...). Figures 1 to 3 (as shown) and heavy crossbeams (such as) Figures 4 to 6 As shown in the figure, they correspond to light and heavy load specifications, respectively.

[0048] As shown in the diagram, lightweight beams have a simpler structure and lower cost, but they have limitations in load-bearing capacity and are prone to deformation when hanging heavy items. Heavy-duty beams, on the other hand, have a more complex structure with more load-bearing components and closed-loop connections, allowing them to support heavier items, but at a higher cost. Both types of beams have their advantages and disadvantages, offering users a wider range of choices.

[0049] Specifically, it includes a long, strip-shaped profile body 100, which can be made of steel, iron, or aluminum alloy and can be extruded. One side of the profile body 100 has a support groove 101 arranged along its length. This location is mainly used to support the scissor bracket 5. The scissor bracket 5 provides a stable connection, improves smooth lifting, and prevents phenomena such as tilting or warping caused by uneven force. It is a conventional connection structure.

[0050] In addition, improvements include:

[0051] A connecting hole 102 is disposed on one side of the profile body 100. This connecting hole 102 can penetrate through a through hole (such as a through hole) in the thickness direction of the profile body 100, or it can not penetrate through the thickness direction of the profile body 100 (such as a blind hole). Figure 12 As shown, the connecting hole 102 needs to be a hole with a certain depth.

[0052] Its orientation can be a horizontal side direction (as shown in the left and right direction in the figure), or a vertical direction (such as...). Figure 11 (The bottom surface of the profile). Of course, it is set on the side of the profile body 100 facing the ceiling (such as...). Figure 2 and Figure 5 The top surface of the profile body 100 is ideal. Furthermore, the connecting holes 102 are positioned close to both ends of the profile body 100 to improve stability. If the connecting holes 102 are too close together, the center of gravity will be unstable, making it easy for clothes to curl up or tilt when hung.

[0053] Additionally, the connector 200 is threaded and fastened to the connecting hole 102. Specifically, the threading method can be that the connector 200 uses an external thread to connect with the internal thread of the connecting hole 102, or the connector 200 uses an internal thread to connect with the external thread of the connecting hole 102.

[0054] In other words, whether it's an external thread or an internal thread, both are threaded connections. The connector 200 can be rotated up or down with the connecting hole 102, thereby changing its own height. Furthermore, one side of the connector 200 has a groove 201 running through its axial direction. This groove 201 is used to hold the steel wire 600. The steel wire 600 does not rotate within the groove 201; a gap exists between them to prevent the steel wire from rotating.

[0055] This structure is completely different from traditional connection methods. This improvement allows for fine-tuning of the height of the connector 200 by raising or lowering it, thereby adjusting the length of the connected steel wire 600. Because the length of the steel wire 600 may change slightly after prolonged use, the fine-tuning of the connector 200's height can accommodate these changes, thus enabling adjustment of the length of each steel wire 600 and ensuring a horizontal lifting state.

[0056] Of course, the longer the axial length of the connector 200, 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 200 can be determined according to actual needs.

[0057] In this embodiment, the connection hole 200 is positioned close to the support groove 101, which is the optimal location. Of course, the connection hole 200 can also be positioned at... Figure 1 , Figure 2 , Figure 4 and Figure 5 The left and right directions are shown.

[0058] refer to Figures 4 to 6 The specifications of the heavy-duty crossbeam are described below. The profile body 100 is provided with a reinforcing wall 104 located between the connecting hole 102 and the support groove 101, and the reinforcing wall 104 extends through the axial direction of the profile body 100. This structure reinforces the position of the connecting hole 102. As can be seen from the figure, the reinforcing wall 104 forms a closed-loop structure, making it less prone to deformation of the profile body 100 under stress, resulting in better overall load-bearing capacity and suitability for hanging heavier items.

[0059] As a further improvement of this utility model, the profile body 100 is provided with a rib plate 105 located below the connecting hole 102 and spaced apart from the connecting hole 102. This further improves the stability of the connection and also limits the required sag height of the connector 200. This structure and... Figure 1 and Figure 2 The limiting rib 103 in the middle has a similar function.

[0060] As a further improvement of this utility model, the two ends of the profile body 100 are respectively provided with insertion cavities 106 for holding the corner brackets 3. Of course, this insertion cavity 106 can be a separate space, or it can share a space with the holding groove 101. The corner brackets 3 are used to connect the lifting longitudinal beams 4, thereby forming a closed-loop lifting frame.

[0061] As a further improvement of this utility model, the end face of the profile body 100 is square or circular. Example 2

[0062] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0063] refer to Figures 7 to 10 This embodiment provides an electric clothes drying rack, including a main unit base 7 fixed to the ceiling, the two being connected by expansion bolts. A drive motor 8 is installed inside the main unit base 7, and the drive end of the drive motor 8 has four steel wires 600. In practice, every two steel wires 600 form a group, with the two groups of steel wires mirror-corresponding and arranged in opposite directions, which is a conventional connection structure.

[0064] The end of the steel wire 600 passes through the groove 201 of the connector 200 for embedded connection, and is limited and connected to the connector 200 by a limiting block 601 at the end, thus achieving positioning connection with the connector 200. The size of the limiting block 601 is larger than the size of the groove 201, so the steel wire 600 will be stably placed in the groove 201 under the obstruction of the limiting block 601. Of course, the size of the limiting block 601 also needs to be adapted to the connecting hole 102.

[0065] This invention improves the traditional crossbeam profile structure, completely changing the way it connects with the steel wire. While achieving a stable lifting connection, it also allows for fine-tuning of the steel wire length by rotating or lowering the connector, thereby ensuring consistent crossbeam height and levelness. It achieves the most stable and reliable effect through the simplest structure.

[0066] 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.

[0067] In addition, the above improvements have limited impact on the modification of profiles, but can significantly reduce the cost of upgrading and modifying existing products and processing costs, thereby enhancing the price advantage of the products.

[0068] 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.
