[0033] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] In the description of the present application, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] In the present application, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0036] The current market airer product usually adds several small cross bars perpendicular to the telescopic rods between the two main telescopic rods to expand the drying space. In the specific installation structure, a groove is usually arranged on the opposite side of the two telescopic rods, and hooks are installed at both ends of the small cross bars. The plug is buckled into the groove of the telescopic rod, and after the telescopic rod is stretched out, the small cross bar can be pushed out along the telescopic rod to expand, so as to realize the purpose of expanding the drying space. However, the existing installation structure of the small cross bar has certain defects: when the small cross bar is expanded, the user needs to push out each small cross bar one by one to disperse the small cross bars, and the convenience of use is poor.

[0037] In order to overcome the above technical problems, with reference to Figures 1-10 The present embodiment provides an airing rack, comprising:

[0038] The fixed frame 1 comprises two parallel fixed airing rods 11;

[0039] The movable frame 2 comprises two telescopic rods 21, small crossbars 22 and linkage rings 23. The two telescopic rods 21 are respectively telescopically installed on the two fixed rods 11. A plurality of small crossbars 22 are slidably installed between the two telescopic rods 21. Any two adjacent small crossbars 22 are sleeved with at least one linkage ring 23. When the telescopic rods 21 are extended relative to the fixed rods 11, the outer small crossbars 22 can pull the inner small crossbars 22 out through the linkage rings 23, thereby realizing linkage expansion of the small crossbars 22.

[0040] The fixed frame 1 is a fixed frame on the drying rack, and two parallel fixed rods 11 are arranged for hanging clothes. In general, in order to improve stability, the fixed frame 1 further comprises a fixed crossbeam (not shown in the figure), and the two ends of the two fixed rods 11 are respectively connected by a fixed crossbeam, thereby forming a stable square frame structure.

[0041] The movable frame 2 is a structure that can be expanded and folded on the drying rack. Each movable frame 2 comprises two parallel telescopic rods 21, and the two telescopic rods 21 are respectively telescopically installed on the fixed rods 11. When the telescopic rods 21 are extended, the drying space can be expanded, and when the telescopic rods 21 are shortened, the volume of the drying rack can be reduced for easy folding and storage. In general, in order to improve stability, each movable frame 2 further comprises an active crossbeam (not shown in the figure), and the end of the telescopic rod 21 that extends out of the fixed rod 11 is the outer end, and the end that is inserted into the fixed rod 11 is the inner end. The active crossbeam connects the outer ends of the two telescopic rods 21. In addition to improving stability, when the movable frame 2 is expanded, the user can also pull the active crossbeam to simultaneously pull out the left and right telescopic rods 21. In order to effectively increase the drying space and improve the balance of the drying rack, one movable frame 2 is usually installed at each end of the fixed frame 1.

[0042] In addition, the movable frame 2 further comprises a plurality of small crossbars 22 that are slidably installed between the two telescopic rods 21. When the movable frame 2 is expanded, the small crossbars 22 can be expanded to provide more drying space. Figure 1 When the movable frame 2 is folded, the small crossbars 22 can be folded at the ends of the fixed frame 1 to facilitate folding of the drying rack. Figure 2 When the movable frame 2 is folded, the small crossbars 22 can be folded at the ends of the fixed frame 1 to facilitate folding of the drying rack.

[0043] The present scheme further comprises linkage rings 23 sleeved between every two adjacent small crossbars 22. When the movable frame 2 is expanded, the outer small crossbar 22 pulls the next inner small crossbar 22 to expand through the connected linkage ring 23. When the movable frame 2 is completely expanded, the expansion of all small crossbars 22 is completed at once. Moreover, the expansion distance between the small crossbars 22 is determined by the length of the linkage rings 23. Therefore, the linkage rings 23 with appropriate lengths can be set according to requirements, thereby achieving the purpose of controlling the expansion distance of the small crossbars 22.

[0044] In summary, the airing rack provided by the embodiment has at least the following effects: through the introduction of the linkage ring 23, the linkage expansion of the small cross bars 22 is realized, the user only needs to operate the extension of the telescopic rod 21, and the small cross bars 22 on the outer side will automatically pull the small cross bars 22 on the inner side one by one to expand through the linkage ring 23, without the need for the user to manually push out each small cross bar 22 one by one, greatly improving the convenience and efficiency of use. The design of linkage expansion ensures that all the small cross bars 22 can be evenly expanded when the telescopic rod 21 is extended, effectively utilizing the airing space of the airing rack, so that the airing of clothes is more orderly and orderly.

[0045] In an embodiment, in combination with Figures 5-7 Each linkage ring 23 includes two long sides and two short sides, the two long sides are arranged in parallel with the telescopic rod 21, and the two short sides are connected to the two long sides from both ends respectively; the small cross bar 22 is provided with an anti-falling groove 2222, the long side is placed in the anti-falling groove 2222, and the long side can slide along the anti-falling groove 2222.

[0046] In this embodiment, the design of the linkage ring 23 includes two long sides and two short sides, the long sides are arranged in parallel with the telescopic rod 21, and the short sides connect the two long sides to form a rectangular frame similar to a long strip or a track-shaped frame. The small cross bar 22 is provided with an anti-falling groove 2222, and the long side of the linkage ring 23 can be placed in and slide along the anti-falling groove 2222, forming a stable connection structure that ensures that the linkage ring 23 can always remain connected to the small cross bar 22 during expansion and contraction, and will not fall off due to external force or improper operation, thereby enhancing the stability and reliability of the entire airing rack; at the same time, it also enables the small cross bar 22 to move smoothly and smoothly during expansion and contraction, which not only improves the convenience of operation, but also reduces the risk of damage caused by friction or jamming, prolonging the service life of the airing rack. In addition, since the linkage ring 23 can slide along the anti-falling groove 2222 of the small cross bar 22, the user can flexibly adjust the position of the linkage ring 23 to control the expansion distance between the small cross bars 22, and this design enables the airing rack to be personalized according to different airing needs, improving the utilization rate of the airing space.

[0047] In an embodiment, along the length extension direction of the telescopic rod 21, any two adjacent linkage rings 23 are arranged in a staggered manner, and the anti-falling groove 2222 provided on each small cross bar 22 corresponds to the number and arrangement position of the connected linkage rings 23.

[0048] Referring to Figure 8When the activity frame 2 is folded, the telescopic rods 21 are mostly retracted into the fixed rods 11, and the plurality of small cross rods 22 are folded into the ends of the fixed rods 11. The present scheme arranges the linkage rings 23 in staggered positions, so that the linkage rings 23 are overlapped side by side after being folded, which avoids the problem of mutual interference between the linkage rings 23 hindering the folding of the small cross rods 22.

[0049] In order to keep the linkage rings 23 stable, in this embodiment, the anti-off grooves 2222 are arranged according to the number and position of the linkage rings 23 to which the small cross rods 22 are connected. The linkage rings 23 are correspondingly buckled in the corresponding anti-off grooves 2222, so that the linkage rings 23 can be kept relatively stable during folding and unfolding. For example, a small cross rod 22 located in the middle needs to be sleeved with two linkage rings 23 on the left and right sides, and the two linkage rings 23 are arranged in staggered positions. Therefore, at least two anti-off grooves 2222 corresponding to the positions of the two linkage rings 23 need to be arranged on the small cross rod 22.

[0050] In one embodiment, referring to Figures 3-4 Each small cross rod 22 comprises a main rod body 221 and two connecting heads 222 connected to both ends of the main rod body 221, and the connecting heads 222 at both ends are respectively connected to the telescopic rods 21 on both sides in a sliding manner.

[0051] Through the special design of the connecting heads 222, the connection between the small cross rods 22 and the telescopic rods 21 is more stable. The connecting heads 222 can ensure that the small cross rods 22 will not fall off due to external force or improper operation during sliding, thereby enhancing the stability and reliability of the entire drying rack. At the same time, the sliding connection design between the connecting heads 222 and the telescopic rods 21 enables the small cross rods 22 to move smoothly and smoothly during unfolding and folding, which reduces the risk of damage caused by friction or jamming and improves the convenience of operation.

[0052] In one embodiment, referring to Figure 6 Along the length extension direction of the telescopic rods 21, any two adjacent connecting heads 222 are sleeved with the same linkage ring 23.

[0053] Each of the small crossbars 22 is provided with a connecting head 222 at each end, and each connecting head 222 is sleeved with a linkage ring 23, in other words, each of the small crossbars 22 is sleeved with a linkage ring 23 at each end. Since each of the small crossbars 22 is sleeved with a linkage ring 23 at each end, a tight and stable linkage system is formed. When the outer small crossbar 22 moves, it will drive the two linkage rings 23 connected at its two ends to move synchronously, and the two linkage rings 23 will simultaneously provide balanced tension to the two ends of the next small crossbar 22 on the inner side at the same time. This balanced tension can avoid the problem of tilting and jamming caused by unbalanced force on the pulled small crossbar 22, and can also avoid the risk of the connecting head 222 at the end of the small crossbar 22 being detached from the telescopic rod 21.

[0054] In an embodiment, referring to Figure 10 , the anti-disengagement groove 2222 is provided on the connecting head 222; wherein a shoulder 2223 is formed on both sides of the anti-disengagement groove 2222, and the side of the shoulder 2223 away from the main rod body 221 is provided with a chamfer 2224, which can guide the linkage ring 23 to pass over the shoulder 2223 and be placed in the corresponding anti-disengagement groove 2222.

[0055] The design of the chamfer 2224 makes it easier for the linkage ring 23 to pass over the shoulder 2223 when installing, thereby smoothly entering the anti-disengagement groove 2222. This not only simplifies the installation process, but also reduces the risk of damage caused by improper installation. Once the linkage ring 23 is correctly placed in the anti-disengagement groove 2222, the shoulder 2223 will act as a barrier to prevent the linkage ring 23 from falling out of the anti-disengagement groove 2222 under stress.

[0056] In an embodiment, in combination with Figures 4-5 , the opposite sides of the telescopic rods 21 on both sides are respectively provided with sliding installation grooves 211, and the connecting heads 222 at both ends are respectively slidingly installed in the sliding installation grooves 211 on both sides, and the linkage rings 23 are arranged in the sliding installation grooves 211.

[0057] The sliding installation grooves 211 provide a stable sliding track for the connecting heads 222, so that the small crossbars 22 can slide smoothly and smoothly on the telescopic rods 21, reducing the risk of jamming or damage caused by poor sliding, and improving the durability and safety of the drying rack. Arranging the linkage rings 23 in the sliding installation grooves 211 not only saves space, but also makes the structure of the entire drying rack more compact, and avoids the problem of affecting normal use and damaging the appearance of the product caused by the exposure of the linkage rings 23.

[0058] In an embodiment, referring to Figure 5The slot opening of the sliding installation groove 211 is provided with an upper stop edge 212 and / or a lower stop edge 213.

[0059] The design of the upper stop edge 212 and / or the lower stop edge 213 and the stop shoulder 2221 on the connecting head 222 together constitute a reliable anti-falling mechanism, which ensures that the connecting head 222 will not accidentally slide out of the sliding installation groove 211 during sliding, thereby greatly improving the connection safety and use stability of the drying rack. In addition, the cooperation of the stop shoulder 2221 with the upper stop edge 212 and / or the lower stop edge 213 not only prevents the falling of the connecting head 222, but also plays a guiding and limiting role, which makes the sliding of the connecting head 222 in the sliding installation groove 211 more stable and smooth, reducing the risk of jamming or damage caused by poor sliding.

[0060] In an embodiment, in combination with Figures 6-9 The linkage ring 23 includes an end linkage ring 231, the outermost small cross bar 22 is separately sleeved with the end linkage ring 231, and the end linkage ring 231 is relatively fixedly arranged with the telescopic rod 21, so that when the telescopic rod 21 is elongated, the outermost small cross bar 22 can be taken out through the end linkage ring 231, and then the remaining small cross bars 22 can be taken out through the remaining linkage rings 23.

[0061] In addition to the end linkage ring 231, the linkage rings 23 connected with the small cross bars 22 at both ends are the connection linkage rings 232. When the telescopic rod 21 is elongated, since the end linkage ring 231 is relatively fixedly arranged with the telescopic rod 21, it can be driven first and moved along the telescopic rod 21. When the end linkage ring 231 abuts against the outermost small cross bar 22 near one end of the fixed drying rod 11, it will drive the small cross bar 22 to move outward and expand, and the small cross bar 22 will drive the connected connection linkage ring 232 to move outward. When the moving connection linkage ring 232 abuts against the next small cross bar 22 inside near one end of the fixed drying rod 11, it will also drive the small cross bar 22 to move outward and expand, and so on. Finally, the purpose of uniformly expanding all the small cross bars 22 is achieved.

[0062] In an embodiment, the end linkage ring 231 is provided with a hook 2311, the outer end of the telescopic rod 21 is provided with a hanging hole, and the hook 2311 is hung on the hanging hole to realize the relative fixation of the end linkage ring 231 and the telescopic rod 21.

[0063] The cooperation of the hook 2311 and the hanging hole makes the fixing of the end linkage ring 231 to the telescopic rod 21 simple and direct. The user can complete the fixing operation without using additional fixing parts or tools, greatly improving the convenience of installation and disassembly. After the hook 2311 is hung on the hanging hole, a reliable fixing point can be formed, ensuring that the end linkage ring 231 will not fall off or shake during the extension or shortening of the telescopic rod 21, enhancing the structural stability of the clothes drying rack and improving the safety of use.

[0064] In an embodiment, the linkage ring 23 is a steel wire ring or a plastic ring.

[0065] Both the steel wire ring and the plastic ring have the advantage of good stability, and both have a certain elastic deformation capacity, which facilitates the sleeving of them on the anti-falling groove 2222 of the connecting head 222.

[0066] On the other hand, a clothes drying machine is provided, comprising the above-mentioned clothes drying rack.

[0067] The clothes drying machine comprises a main machine, a lifting mechanism and a clothes drying rack. The main machine can be installed under the ceiling. The main machine is connected with the clothes drying rack through the lifting mechanism, and the lifting of the clothes drying rack can be controlled through the lifting mechanism.

[0068] Based on the structure of the clothes drying rack of the embodiment, the clothes drying machine of the embodiment can quickly deploy the movable frame 2 to expand the drying space according to the use demand, and each small horizontal rod 22 can be automatically unfolded during the deployment process, having the advantages of simple operation and good experience.
