Description

Technical Field

[0001] This application relates to the technical field of home appliances, and more particularly to a clothes rack and clothes drying machine. Background Technology

[0002] In current double-pole clothes drying racks, to expand the drying space, some models vertically install several sliding crossbars between the two clothes poles. These crossbars can be unfolded along the clothes poles for hanging small items of clothing when in use; they can be folded up when not in use. More advanced models feature telescopic clothes poles, with the crossbars installed between the telescopic poles on both sides. Furthermore, the telescopic poles contain linkage components that connect to the crossbars. When the user pulls the telescopic pole to extend it, the linkage components automatically extend simultaneously, and the extended linkage components automatically unfold the crossbars. In this structure, the end of the linkage component needs to be fixed to the end of the telescopic pole to achieve the desired extension.

[0003] Currently, the end linkage rod is fixed by directly engaging with the limiting block at the end of the telescopic rod using a spring-loaded buckle. While the spring-loaded buckle structure is simple, it is prone to deformation under stress. During rapid extension or when jamming occurs, the spring-loaded buckle is susceptible to elastic deformation due to excessive force, leading to detachment from the limiting block. Therefore, resolving the reliability issue of the end fixing structure of the linkage rod assembly has become a critical problem urgently needing to be solved in the current technology of double-pole clothes drying racks. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a clothes rack and clothes drying machine that can solve the above-mentioned problems existing in the prior art.

The hook extends into the first clearance hole and the second clearance hole to engage with the limiting part of the adapter frame.

[0021] On the other hand, a clothes drying rack is provided, including the aforementioned clothes rack.

[0022] The beneficial effects of this application are as follows: The clothes rack provided in this application, by setting anti-detachment protrusions and anti-detachment holes, effectively prevents the hooks from disengaging from the limiting part, greatly improving the connection stability between the linkage rod and the main body of the clothes rack.

[0035] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in 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] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In modern home life, clothes drying racks are an essential piece of equipment for daily laundry drying, and their functionality and practicality are of great concern. As people's living standards improve, the requirements for clothes drying racks are no longer limited to meeting basic drying needs; more emphasis is placed on the rational utilization of drying space and ease of operation. To further expand the drying space of double-pole clothes drying racks and better meet users' needs for drying small items of clothing (such as socks and underwear), the industry has implemented many innovative designs. For example, some double-pole clothes drying racks have several sliding crossbars vertically installed between the two parallel drying poles. This design allows users to easily spread the crossbars to both sides according to their actual drying needs, thereby increasing the additional drying area and facilitating the hanging of various small items of clothing, effectively improving the space utilization of the clothes drying rack. When not in use, the crossbars can be folded together, making the clothes drying rack more neat and organized, without taking up too much space.

[0039] With the continuous progress of technology, the drying rods of some drying machines adopt a telescopic form. This design enables the drying machine to be retracted when not in use, further saving space; and when it is necessary to dry clothes, it can quickly extend to provide a larger drying area. The small crossbars are cleverly installed between the telescopic rods on both sides, forming an organic whole. At the same time, a linkage rod assembly connected to each small crossbar is carefully arranged inside the telescopic rod. This innovative design realizes the linkage between the telescopic rod and the small crossbar. When the user pulls the telescopic rod to make it extend, the linkage rod assembly will synchronously and automatically extend, and the extended linkage rod assembly will automatically drive the small crossbars to spread out, without the user manually operating each small crossbar one by one, greatly improving the convenience and efficiency of use.

[0040] However, in the existing such linkage structure, to achieve the extension of the linkage rod assembly when the telescopic rod extends, the key lies in firmly fixing the end of the linkage rod assembly to the end of the telescopic rod. Currently, the commonly adopted method in the industry is to directly fasten the end linkage pull rod to the limit stop on the end of the telescopic rod through a spring-back buckle. The spring-back buckle structure has the advantages of simple design and low cost, and can meet the basic fixing requirements to a certain extent, but it is prone to force deformation. When pulling quickly or encountering jams during the unfolding process, the spring-back buckle is likely to undergo elastic deformation due to excessive force, and then cause the hook to disengage from the limit stop. This will affect the normal use of the drying machine, resulting in the small crossbars being unable to spread out or fold back normally. Therefore, how to solve the reliability problem of the fixing structure at the end of the linkage rod assembly has become a key problem亟待解决 in the technical field of double-rod drying machines.

[0041] To overcome the above technical problems, as Figures 1-5 shown, the embodiment of the present application provides a drying rack, including:

[0042] The drying rack main body 1, including a drying rod 11;

[0043] The limiting member 4, fixed to the drying rack main body 1, including a limiting portion 41;

[0044] The linkage pull rod 3, telescopically arranged along the length direction of the drying rod 11, including a plurality of telescopic joints 31. The telescopic joint 31 at the end is provided with a hook 311, and the hook 311 is arranged in cooperation with the limiting portion 41; during the extension process of the linkage pull rod 3, the movement of the corresponding telescopic joint 31 is restricted by the fastening of the limiting portion 41 and the hook 311.

[0045] Among them, in one of the limiting portion 41 and the hook 311, a anti-disengagement hole 42 is provided, and a corresponding anti-disengagement protrusion 312 is provided on the other one. The anti-disengagement protrusion 312 is fastened to the anti-disengagement hole 42 to prevent the hook 311 from disengaging from the limiting portion 41.

[0046] The function of the linkage rod 3 in this embodiment is to pull the small horizontal bars 2 to unfold for use. Specifically, two drying rods 11 are arranged in parallel, and several small horizontal bars 2 are vertically installed between the two drying rods 11. By sliding each small horizontal bar 2 along the drying rod 11, the small horizontal bars 2 can be unfolded or gathered. For ease of use, this solution also includes a linkage rod 3 along the length of the drying rod 11. The linkage rod 3 includes multiple telescopic joints 31, each telescopic joint 31 connected to a small horizontal bar 2. Therefore, when the telescopic joints 31 extend relative to each other, they can cause the small horizontal bars 2 to spread out; when the telescopic joints 31 retract relative to each other, they can cause the small horizontal bars 2 to gather. In actual use, the user can push or pull one of the small horizontal bars 2 to extend the linkage rod 3, thereby quickly causing all the small horizontal bars 2 to spread out. Alternatively, when the drying rod 11 is telescopic, the user can directly pull the telescopic rod to extend, thereby extending the linkage rod 3 and causing all the small horizontal bars 2 to spread out. Based on this embodiment, users do not need to operate each small horizontal bar 2 individually during use, which greatly improves the convenience and efficiency of operation. At the same time, after unfolding, the length of each telescopic joint 31 can be used to stably control the spacing of each small horizontal bar 2, avoiding the problem of each small horizontal bar 2 sliding and gathering together during use, which would affect drying.

[0047] It is understandable that in order to achieve the function of extending the linkage rod 3, at least one end of the linkage rod 3 needs to be fixed. When in use, pulling the other end of the linkage rod 3 will cause the linkage rod 3 to extend, thereby causing the small crossbars 2 to unfold. Therefore, in this embodiment, a hook 311 is provided at the telescopic joint 31 at the end of the linkage rod 3, and a limiting member 4 is fixedly provided in the clothes rack body 1. In the assembled state, the hook 311 is engaged with the limiting member 4, and the telescopic joint 31 at the very end of the linkage rod 3 is locked and cannot move. When the remaining telescopic joints 31 are pulled by external force, the remaining telescopic joints 31 can be stably extended relative to the fixed end telescopic joint 31, thus realizing the function of stable extension of the linkage rod 3.

[0048] Assuming the extension direction of the linkage rod 3 is the first direction, the engagement of the hook 311 with the limiting member 4 can at least restrict the movement of one telescopic joint 31 at the end along the first direction. However, to facilitate the engagement and installation of the hook 311, the movement of the hook 311 along the second direction (the direction perpendicular to the first direction) is usually not completely restricted. This allows the hook 311 to undergo a certain degree of elastic deformation relative to the limiting member 4 along the second direction during assembly. After the hook 311 passes the limiting part 41, it will then elastically return to the limiting part 41 and latch onto it again. Under this mechanism, when the tension in the first direction of the hook 311 is too large, it may still elastically deform along the second direction, causing a disengagement problem. To address this, this embodiment provides a mutually cooperating anti-detachment protrusion 312 and anti-detachment hole 42 on both the limiting part 41 and the hook 311. When the hook 311 is fastened to the limiting part 41 (limiting the telescopic joint 31 at the end to move in the first direction), the anti-detachment protrusion 312 and the anti-detachment hole 42 engage, thereby restricting the degree of freedom of the hook 311 to move in the second direction, thus preventing the hook 311 from detaching from the limiting part 41.

[0049] In summary, in this embodiment, by setting the anti-detachment protrusion 312 and the anti-detachment hole 42, the hook 311 is effectively prevented from disengaging from the limiting part 41, greatly improving the connection stability between the linkage rod 3 and the clothes rack body 1. This enhances the overall structural reliability of the clothes rack, reduces the possibility of malfunctions during use, extends the service life of the clothes rack, and lowers maintenance costs.

[0050] In specific implementation, optionally, sliding grooves are provided on the opposite sides of the two drying rods 11, and sliding connectors are provided at both ends of the small horizontal bar 2. The installation of the small horizontal bar 2 is achieved by the cooperation of the sliding connectors and the sliding grooves.

[0051] Furthermore, the linkage rod 3 is installed within the sliding groove, achieving concealed installation and facilitating connection with the small crossbar 2. During installation, the linkage rod 3 can be installed on one or two of the drying rods 11 as needed.

[0052] In one embodiment, combined with Figure 7 and Figure 8 The hook 311 includes a support arm 3111 and a fastening part 3112. One end of the support arm 3111 is fixedly connected to the telescopic joint 31, and the other end is provided with the fastening part 3112. The hook 311 is fastened to the limiting part 41 through the fastening part 3112.

[0053] One end of the support arm 3111 is fixedly connected to the telescopic joint 31 of the linkage rod 3, and the other end is provided with a fastening part 3112, which provides a structural basis for the fastening of the hook 311 and the limiting part 41. The fastening part 3112 is the key part for the hook 311 to achieve the fastening function with the limiting part 41. Its shape and structural design must match the limiting part 41 to ensure that they can be stably and reliably fastened together, thereby restricting the movement of the telescopic joint 31 in a specific direction.

[0054] During the assembly of the clothes rack, because the support arm 3111 has a certain degree of elasticity, the hook 311 can undergo a certain elastic deformation relative to the limiting part 41 in a specific direction (usually perpendicular to the extension direction of the linkage rod 3). Therefore, the operator brings the hook 3111's engaging part 3112 close to the limiting part 41 and applies a certain external force to cause the support arm 3111 to bend elastically, so that the engaging part 3112 passes over the limiting part 41. After the engaging part 3112 passes over the limiting part 41, the support arm 3111 returns to its original shape due to its own elasticity, and the engaging part 3112 is fastened to the limiting part 41, thereby achieving the initial fastening of the hook 311 and the limiting part 41.

[0055] In this embodiment, the hook 311 has a relatively simple structure consisting of a support arm 3111 and a fastening part 3112. This simple structural design makes its manufacturing process relatively easy to implement. During production, common metal processing or plastic molding processes can be used for mass production, reducing production costs and improving production efficiency. During the assembly of the clothes rack, the fastening operation between the hook 311 and the limiting part 41 is relatively simple. The operator only needs to utilize the elasticity of the support arm 3111 to complete the fastening through a simple pushing action, without the need for complicated tools or cumbersome steps. This not only improves assembly efficiency and reduces assembly time, but also reduces the possibility of errors during assembly, which helps to ensure product quality.

[0056] In one embodiment, the fastening part 3112 and / or the limiting part 41 are provided with a first guide surface 3113, which can guide the hook 311 into the fastening position with the limiting part 41.

[0057] When the first guide surface 3113 is provided on the fastening part 3112, with reference to the unfastened state, part or all of the side of the fastening part 3112 facing the limiting part 41 is designed as a guide surface with a certain inclination angle or curvature. This guide surface can be a plane or a curved surface, and its shape and size are designed according to the specific structure of the hook 311 and the limiting part 41 and the fastening requirements. Similarly, if the first guide surface 3113 is provided on the limiting part 41, with reference to the unfastened state, the surface of the limiting part 41 facing the fastening part 3112 will be processed into a guide surface with a certain inclination angle or curvature, so that the hook 311 can smoothly slide into the groove along this inclined surface when it approaches, thus achieving fastening. Of course, both the fastening part 3112 and the limiting part 41 can be provided with the first guide surface 3113.

[0058] When the hook 311 engages with the limiting part 41, the first guide surface 3113 comes into play. Specifically, as the hook 311 gradually approaches the limiting part 41, the first guide surface 3113 changes the direction of movement of the hook 311, causing it to move towards the correct engagement path. For example, if the hook 311 approaches the limiting part 41 in the horizontal direction, but the engagement position is offset in the vertical direction, the tilt angle of the guide surface will cause the hook 311 to gradually change its direction of movement during the approach, moving closer to the engagement position. After the engagement part 3112 passes the limiting part 41, the support arm 3111 will spring back, allowing the engagement part 3112 to complete the engagement with the limiting part 41.

[0059] In this embodiment, the first guide surface 3113 simplifies the assembly process, reduces the time and labor costs required for assembly, and allows operators to complete assembly tasks more quickly, thus improving production efficiency. On the other hand, since the guide surface can tolerate a certain degree of assembly error, it reduces the requirements for the machining accuracy of parts, thereby reducing machining costs. For example, when machining the fastening part 3112 and the limiting part 41, it is not necessary to use overly complex machining processes and strict tolerance control to meet the assembly requirements.

[0060] In one embodiment, reference is made to Figure 8 The anti-detachment hole 42 or the anti-detachment protrusion 312 is provided on the fastening part 3112 and is spaced apart from the support arm 3111.

[0061] In this embodiment, the anti-detachment hole 42 or the anti-detachment protrusion 312 is set at a distance from the support arm 3111, so that the anti-detachment structure has a relatively independent working space. When the hook 311 is subjected to external force, the anti-detachment structure can independently play the role of anti-detachment, without being too affected by the deformation of other parts of the support arm 3111, thereby improving the reliability of anti-detachment.

[0062] In one embodiment, the sidewall of the anti-detachment hole 42 and / or the anti-detachment protrusion 312 are provided with a second guide surface 3121. The second guide surface 3121 is provided on the opposing sidewalls of the anti-detachment hole 42 and the anti-detachment protrusion 312, and the second guide surface 3121 can guide the anti-detachment protrusion 312 to be embedded in the anti-detachment hole 42.

[0063] Similarly, the second guide slope is set as a slope with a certain inclination angle or a curved surface with a certain curvature. During the process of the anti-detachment protrusion 312 approaching the anti-detachment hole 42, the second guide surface 3121 first plays its role. When the two are close, due to the presence of the second guide surface 3121, even if there is a certain deviation in the initial position of the anti-detachment protrusion 312 and the anti-detachment hole 42, the second guide surface 3121 will change the movement direction of the anti-detachment protrusion 312, causing it to move closer to the center of the anti-detachment hole 42. For example, if the anti-detachment protrusion 312 is slightly biased to one side of the anti-detachment hole 42, the second guide surface 3121 on that side will apply a force towards the center to the anti-detachment protrusion 312, guiding it back to the correct embedding path. This ensures that it will not deviate or jam during the embedding process, ultimately achieving a tight fit between the anti-detachment protrusion 312 and the anti-detachment hole 42, achieving a good anti-detachment effect. In addition, the second guide surface 3121 allows the operator to assemble the hook 311 without precisely aligning the anti-detachment protrusion 312 and the anti-detachment hole 42. The operator only needs to bring the anti-detachment protrusion 312 approximately close to the anti-detachment hole 42, and the second guide surface 3121 will automatically guide it to be inserted, which greatly simplifies the assembly process and reduces the time and effort required for assembly.

[0064] In one embodiment, reference is made to Figure 7 The fastening part 3112 has a protruding anti-detachment protrusion 312 on one side for fastening with the limiting part 41, and the support arm 3111 has a demolding hole 3114 corresponding to the position of the anti-detachment protrusion 312.

[0065] Generally, the hook 311 and the telescopic joint 31 it connects to are manufactured using a one-piece injection molding process. One-piece injection molding offers advantages such as high production efficiency, low cost, and good product precision. It integrates the hook 311 and the telescopic joint 31 into a single unit, reducing assembly steps and connecting parts, and improving the overall performance of the product. Since the telescopic joint 31 is elongated, the mold opening direction is preferably perpendicular to the length direction of the telescopic joint 31 for easy demolding. With this mold opening method, if the anti-detachment protrusion 312 is directly connected to the support arm 3111 without a demolding hole 3114, the moving mold core will be unable to be smoothly extracted after molding the anti-detachment protrusion 312 due to the obstruction of the support arm 3111, leading to demolding difficulties. This design incorporates a demolding hole 3114 on the support arm 3111, corresponding laterally to the anti-detachment protrusion 312. This allows the moving mold core to pass through the support arm 3111. During injection molding, molten plastic fills the mold cavity, forming the hook 311 and the telescopic joint 31, including the anti-detachment protrusion 312. After injection molding is complete, the moving mold core can be extracted through the demolding hole 3114, thus achieving the molding of the anti-detachment protrusion 312 and the smooth demolding of the entire product.

[0066] In this embodiment, by providing a demolding hole 3114, the demolding problem of the anti-demolding protrusion 312 during the one-piece injection molding process is solved, avoiding production interruptions and mold damage caused by demolding difficulties, and greatly improving production efficiency. In addition, a smooth demolding process can reduce damage to the product during demolding, ensuring the product's appearance quality and dimensional accuracy.

[0067] In one embodiment, reference is made to Figure 1 The clothes rack body 1 includes two parallel drying rods 11, and an end beam 12 is vertically connected between the ends of the two drying rods 11. The limiting member 4 is fixed to the end beam 12.

[0068] The main body 1 of the clothes rack includes two parallel drying rods 11. This parallel arrangement allows the rods 11 to form a stable structural frame, providing ample space for drying clothes. The drying rods 11 are typically made of materials with sufficient strength and rigidity, such as aluminum alloy or stainless steel, to ensure they can withstand the weight of the clothes without significant deformation. The shape of the drying rods 11 can be round, square, or other shapes suitable for drying, and their surfaces are generally smoothed to prevent scratching clothes. An end beam 12 is vertically connected between the ends of the two drying rods 11. The end beam 12 connects and reinforces the two drying rods 11, forming a stable rectangular frame structure for the entire clothes rack body 1. The vertical connection between the end beam and the drying rods 11 can be achieved through welding, bolting, or snap-fit ​​connections, depending on the materials and manufacturing process used.

[0069] The limiting member 4 is installed on the end crossbeam 12, which corresponds exactly to the end of the drying rod 11. This locks the end expansion joint 31 to the end of the drying rod 11, making full use of the length of the drying rod 11 to install the linkage rod 3 and the small crossbeam 2. At the same time, the end crossbeam 12, which is perpendicular to the drying rod 11, can provide a stable and reliable installation space for the limiting member 4, ensuring its installation reliability and thus ensuring the stability of the limiting of the end expansion joint 31.

[0070] In one embodiment, reference is made to Figures 4-7 The end crossbeam 12 includes a crossbeam body 121 and a transition frame 122. The transition frame 122 is located on the inner side of the corner where the crossbeam body 121 is connected to the drying rod 11. The crossbeam body 121 and the drying rod 11 are connected through the transition frame 122.

[0071] The adapter frame 122 serves as the limiting member 4.

[0072] The adapter frame 122, located inside the corner, can more effectively transfer the force borne by the drying rod 11 to the main body of the crossbeam 121. Compared with directly connecting the main body of the crossbeam 121 and the drying rod 11, connecting through the adapter frame 122 can increase the contact area and the number of connection points. The adapter frame 122 can be customized according to the shape of the drying rod 11 and the main body of the crossbeam 121, making the connection tighter and stronger, and improving the tensile and shear resistance of the connection. Placing the adapter frame 122 inside the corner makes full use of the space at the end of the clothes rack, avoiding the need for additional connecting parts or limiting parts 4 on the outside, making the overall appearance of the clothes rack simpler and more beautiful.

[0073] Preferably, the adapter frame 122 is made of high-strength aluminum alloy, stainless steel or other materials, and it is connected to the crossbeam body 121 and the drying rod 11 by bolts.

[0074] Importantly, in this embodiment, the adapter frame 122 is also used as a limiting component 4 that cooperates with the hook 311 to fasten, eliminating the need to add a separate limiting component. This achieves multiple uses for one item, reduces the number of parts, and simplifies the structure of the clothes rack. This not only helps to reduce production costs but also facilitates the installation and maintenance of the clothes rack.

[0075] Among them, reference Figure 7 To ensure the strength of the adapter frame 122, it adopts a complete plate structure. To avoid serious strength damage, a buckle hole 43 is opened in the middle of the adapter frame 122 to allow the buckle hook 311 to pass through. A limiting part 41 is formed on one side of the buckle hole 43. When the buckle hook 311 passes through the buckle hole 43, the buckle hook 311 can be fastened to the limiting part 41 on the side of the buckle hole 43, thereby realizing the buckling and locking function.

[0076] In one embodiment, reference is made to Figure 5The end beam 12 also includes an end plug 123. The main body 121 of the beam has a through-tube structure, and the end plugs 123 are respectively installed at both ends of the main body 121 of the beam.

[0077] The main body 121 of the crossbeam is provided with a first clearance hole 1211 corresponding to the hook 311, and the end plug 123 is provided with a second clearance hole 1231 corresponding to the hook 311. The hook 311 extends into the first clearance hole 1211 and the second clearance hole 1231 to engage with the limiting part 41 of the adapter frame 122.

[0078] The main body 121 of the crossbeam, as the core part of the end crossbeam 12, undertakes the important task of connecting the ends of the two drying rods 11, providing the main structural support for the entire end of the clothes rack, and maintaining the stability of the clothes rack frame. The use of a through-tube structure can reduce the weight of the main body 121 of the crossbeam while ensuring a certain strength, thereby reducing material costs, and also facilitates the installation of internal wiring (if the clothes rack has an electric function) or other accessories.

[0079] End plugs 123 are installed at both ends of the main body of the crossbeam 121, serving to seal the through-tube structure, preventing dust, debris, etc. from entering the interior of the crossbeam, protecting any wiring or accessories inside, and also enhancing the aesthetics of the clothes rack.

[0080] The first clearance hole 1211 provided on the main body of the crossbeam 121 and the second clearance hole 1231 provided on the end plug 123 provide space for the hook 311 to engage with the limiting part 41 of the adapter frame 122, so that the hook 311 can extend smoothly and cooperate with the limiting part 41 to realize the limiting function.

[0081] On the other hand, a clothes drying rack is provided, including the aforementioned clothes rack.

[0082] Similarly, based on the clothes rack provided in this embodiment, the linkage rod 3 in the clothes drying machine of this embodiment can be reliably and stably installed in the clothes rack body 1, ensuring its stability and durability in use.
