DETAILED DESCRIPTION

[0039] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the embodiment of the utility model is further described in detail below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor belong to the range of the utility model protection.

[0040] In the description of the utility model, unless another explicit stipulation and limitation, the term "link" "connect" "fix" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or be integrated;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be the communication of two elements or the interaction of two elements. For the person skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0041] In the utility model, unless another explicit stipulation and limitation, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or 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 "on" 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 "under", "below" and "under" 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.

[0042] The clothes drying machine is a common drying tool in modern home life, which can realize the lifting of the drying rod through manual or electric mode, thereby facilitating the user to dry clothes. It can be understood that the lifting drying rod generally includes manual and electric types, and no matter the manual or electric clothes drying machine, it includes a power unit for pulling the drying rod to lift. In the manual clothes drying machine, the power unit can be set as a hand crank or the like control component, and the lifting of the drying rod is realized by the hand crank controlling the winding reel to wind or unwind the rope, and the structure is relatively simple. In the electric clothes drying machine, the power unit is generally set as a motor, and the winding or unwinding of the rope is realized by the driving force generated by the motor, and the motor is usually equipped with a remote control function, so that the user can easily control the lifting of the drying rod from a distance.

[0043] From the background art, it can be known that no matter the manual or electric clothes drying machine, it generally adopts a traction member (such as a steel wire rope, a transmission belt, etc.) to pull the drying rod to lift in the vertical direction relative to the main support, but due to the reasons such as the generally long length of the drying rod, the length deviation of the traction member, the assembly error of the components, and the component deformation, the drying rod may be inclined and deviated relative to the main support, which will cause that only one end of the drying rod can be lifted to abut against the main support during the lifting and storage process, and the other end of the drying rod always keeps a certain gap with the main support, resulting in that the drying rod cannot be completely stored and fixed on the main support. The inclination of the drying rod relative to the main support in the storage state may cause the connection member (such as a pulley, a support, etc.) between the drying rod and the main support to bear uneven force, which will accelerate the wear of these components in the long run, and even may cause the connection to be loose or broken. The inclined drying rod may also affect the overall structural stability of the product, so that it is more likely to shake or collapse during use, which exists certain safety hazards. In addition, due to the fact that the drying rod cannot keep a horizontal state, the clothes to be dried cannot be evenly hung, so that the user may need to additionally adjust the position of the clothes or keep balance when using the inclined drying rod, which increases the complexity and inconvenience of use, and also affects the overall appearance of the product, so that it is not coordinated with the home environment.

[0044] Therefore, the present embodiment provides a drying rod leveling mechanism which can be applied to the clothes drying machine mentioned in the above content. The drying rod leveling mechanism sets the pulley assembly to be movable relative to the wheel frame, and sets a leveling component between the wheel frame and the pulley assembly to realize the adjustment of the height position of the pulley assembly on the wheel frame, thereby solving a series of problems caused by the inclination of the drying rod.

[0045] Please refer to the accompanying drawings Figures 1-3The clothesline leveling mechanism comprises a wheel frame 10, a pulley assembly 20, and a leveling component 30. The wheel frame 10 serves as the support base of the clothesline leveling mechanism, and is usually provided as a frame structure with certain structural strength. In the actual application scenario of the clothes drying machine, the wheel frame 10 is used to be installed on the main support 50 of the clothes drying machine, which serves as the support base of the clothes drying machine and provides corresponding installation positions and spaces for the related components (such as the power unit mentioned above) of the clothes drying machine. The wheel frame 10 needs to be able to bear the weight of the pulley assembly 20, the clothesline 60, and the clothes being dried, so the design and material selection of the wheel frame 10 need to ensure that it can withstand various loads in daily use and maintain the structural integrity and stability. The pulley assembly 20 is used to connect the drying assembly of the clothes drying machine, and is rotatably arranged on the wheel frame 10. The drying assembly in the embodiment refers to the components (such as the clothesline 60 and the traction member 53) used to provide corresponding hanging spaces and positions for the clothes and other drying objects in the clothes drying machine. Moreover, the pulley assembly 20 has the freedom to move up and down relative to the wheel frame 10. In the actual application scenario of the clothes drying machine, the pulley assembly 20 is used to provide the winding position of the traction member 53, which protects, supports, and guides the traction member 53, so that the traction member 53 can be connected to the clothesline 60 while turning on the main support 50, and ensure that the traction member 53 maintains the correct path and tension during the lifting and lowering of the clothes drying machine, so that the clothesline 60 remains balanced during lifting and lowering, and reduces shaking.

[0046] In the actual application scenario, the traction member 53 is wound around the pulley assembly 20, one end of which is connected to the clothesline 60, and the other end is connected to the retracting device for retracting the traction member 53. The retracting device is operated manually or electrically to enable the traction member 53 to pull or release the clothesline 60, so that the clothesline 60 can be lifted and lowered relative to the main support 50. Therefore, it can be understood that, under the condition that the length of the traction member 53 remains unchanged and the position of the connection end of the retracting device remains unchanged, the height position of the pulley assembly 20 on the wheel frame 10 determines the height position of the end of the traction member 53 connected to the clothesline 60. That is, when the height position of the clothesline 60 needs to be adjusted, the relative position of the pulley assembly 20 and the wheel frame 10 can be adjusted to achieve the adjustment.

[0047] In the above matching form, the pulley assembly 20 can not only rotate relative to the wheel frame 10 under the circumferential force, but also can move up and down relative to the wheel frame 10 under the vertical radial force. In addition to being able to provide support for the pulley assembly 20, the wheel frame 10 also plays a role in limiting the stroke of the pulley assembly 20 in the vertical direction in an embodiment, so that the pulley assembly 20 can move between the lowest point and the highest point of the stroke under the limitation of the wheel frame 10. Of course, in other embodiments, the active stroke of the pulley assembly 20 on the wheel frame 10 can also be limited by other limiting structures, such as the lifting stroke of the pulley assembly 20 can be constrained by the stop block or other structures arranged on the wheel frame 10 or outside the wheel frame 10, and the present embodiment is not strictly limited and required here.

[0048] It should be explained that the movement direction of the lifting movement of the pulley assembly 20 relative to the wheel frame 10 is usually perpendicular to the horizontal direction, but it can be inclined to the horizontal direction as long as the horizontal height of one end of the pulley assembly 20 is greater than that of the other end.

[0049] It should be noted that in the present example, the pulley assembly 20 and the wheel frame 10 are not necessarily arranged to have a direct physical connection relationship, and the two can be connected through other connecting components to form an indirect connection relationship.

[0050] According to the above content, by adjusting the horizontal height of the pulley assembly 20, the height position of the clothes drying rod 60 can be adjusted in the application of the clothes drying machine. Therefore, in order to allow the pulley assembly 20 to be adjusted according to the actual operation of the operator, the clothes drying rod leveling mechanism of the present embodiment further comprises a leveling component 30. In the present embodiment, the leveling component 30 is arranged between the wheel frame 10 and the pulley assembly 20 to allow the operator to manually adjust the pulley assembly 20, thereby controlling the movement of the pulley assembly 20 in the height direction on the wheel frame 10. The present embodiment sets the leveling component 30 as a manual adjustment, which can effectively simplify the structural complexity and weight of the clothes drying rod leveling mechanism, effectively reduce the burden on the ceiling or suspended ceiling caused by the clothes drying machine, and meet the lightweight design requirements of the clothes drying machine.

[0051] It can be understood that the leveling component 30 can include a knob, a bolt, a push-pull rod or other similar adjustment device.

[0052] In actual operation, the operator will change the height or position of the pulley assembly 20 by adjusting the leveling component 30 according to the actual inclination of the clothes drying rod 60, so as to change the horizontal height of the corresponding position of the clothes drying rod 60. This adjustment can be subtle to ensure that the entire clothes drying rod reaches a precise horizontal state.

[0053] In order to enable the pulley assembly 20 to be adjusted under the action of the leveling component 30, the pulley assembly 20 needs to be movably connected with the wheel frame 10 through the leveling component 30. For example, the pulley assembly 20 and the wheel frame 10 can be connected in the following manner, but are not limited to:

[0054] I. The leveling component 30 and the wheel frame 10 are movably connected in the lifting direction. During the operation of the operator on the leveling component 30, the leveling component 30 and the pulley assembly 20 are relatively fixed in the height direction, and the leveling component 30 drives the pulley assembly 20 to move in the lifting direction relative to the wheel frame 10, so as to realize the adjustment of the height position of the pulley assembly 20.

[0055] II. The leveling component 30 and the pulley assembly 20 are movably connected in the lifting direction. During the operation of the operator on the leveling component 30, the leveling component 30 and the wheel frame 10 are relatively fixed in the height direction, and the leveling component 30 drives the pulley assembly 20 to move in the lifting direction relative to the wheel frame 10.

[0056] III. The leveling component 30 and the wheel frame 10 are movably connected in the lifting direction, and the leveling component 30 and the pulley assembly 20 are movably connected in the lifting direction. During the operation of the operator on the leveling component 30, the leveling component 30 and the wheel frame 10, and the leveling component 30 and the pulley assembly 20 will all move in the height direction. Finally, the pulley assembly 20 and the wheel frame 10 are lifted.

[0057] It should be noted that in the implementation mode in which the leveling component 30 and the wheel frame 10 and the leveling component 30 and the pulley assembly 20 are movably adjusted in the lifting direction, the relative motion direction of the leveling component 30 and the wheel frame 10 is opposite to the relative motion direction of the leveling component 30 and the wheel frame 10, or in the case where the relative motion direction of the leveling component 30 and the wheel frame 10 is consistent with the relative motion direction of the leveling component 30 and the wheel frame 10, the motion speed of the two is different, so as to avoid the situation that the wheel frame 10 and the pulley assembly 20 are relatively stationary and cannot be adjusted in height during the movement of the two relative to the leveling component 30.

[0058] The leveling mechanism of the clothes drying rod can directly adjust the height position of the pulley assembly 20 on the wheel frame 10 through the leveling component 30, thereby keeping the structure stable during use, prolonging the service life of the component, and ensuring the appearance of the product. At the same time, the pulley assembly 20 (clothes drying rod 60) is movably connected to the wheel frame 10 (main support 50) through the leveling component 30, so that the clothes drying rod 60 does not need to be disassembled during leveling, and the user can adjust the levelness of the clothes drying rod 60 at any time in the installed state. Even if the clothes drying rod 60 is tilted after installation, or the position of the clothes drying rod 60 deviates as the product is used for a long time, the user can easily and quickly adjust the levelness of the clothes drying rod 60, which is convenient for the user and improves the safety performance of the product, reducing the risk of user operation.

[0059] In an embodiment, the leveling component 30 includes an operating part and an adjusting part, wherein the operating part is connected to the adjusting part to allow the mutual transmission of acting force therebetween, and the adjusting part is movably connected to the wheel frame 10 and / or the pulley assembly 20, so that the adjusting part can move in the lifting direction relative to at least one of the wheel frame 10 and the pulley assembly 20 during relative movement of the adjusting part relative to the wheel frame 10 and the pulley assembly 20, thereby allowing the wheel frame 10 and the pulley assembly 20 to move in the lifting direction, and realizing the leveling operation of the clothes drying machine.

[0060] The operating part is located outside the wheel frame 10 and provides an operating position for the user to operate the leveling component 30, so that the user can drive the adjusting part to move relative to the wheel frame 10 and the pulley assembly 20 through the operating part.

[0061] Please continue to refer to the accompanying drawings Figures 1-3In order to enable the pulley assembly 20 to rotate smoothly on the wheel frame 10, the pulley assembly 20 comprises a wheel shaft 21 and a pulley body 22. The wheel shaft 21 and the pulley body 22 are connected in some way (such as welding, bolt connection, etc., threading) to ensure close cooperation and coordinated work between the two, and the wheel shaft 21 is arranged on the wheel frame 10, thereby realizing the effect of the pulley body 22 rotating relative to the wheel frame 10 under the action of external force. Correspondingly, the pulley body 22 is the part around the wheel shaft 21, and the outer peripheral part of the pulley body 22 in the rotating direction is usually designed with a groove or a channel to accommodate and fix the transmission element 53 and other transmission elements. In the pulley assembly 20, the wheel shaft 21 and the pulley body 22 work together to realize force transmission, conversion and motion control of the transmission element 53. When the take-up device (such as the motor assembly 52 described later) acts on the pulley assembly 20 through the transmission element 53, the pulley body 22 will rotate around its axis to reduce the friction force generated between the pulley body 22 and the transmission element 53 during the lifting of the clothes drying rod 60.

[0062] On the basis that the pulley body 22 is sleeved on the wheel shaft 21, in order to ensure that the pulley body 22 can rotate relative to the wheel frame 10, the following connection modes can be adopted between the wheel shaft 21, the pulley body 22 and the wheel frame 10 to realize the above effect:

[0063] I. The wheel shaft 21 is threadedly connected to the pulley body 22 so that the pulley body 22 can rotate relative to the wheel shaft 21. In this embodiment, the wheel shaft 21 can be arranged to be circumferentially fixed to the wheel frame 10 to ensure the structural stability between the pulley assembly 20 and the wheel frame 10.

[0064] II. The wheel shaft 21 is rotatably connected to the wheel frame 10. In this embodiment, the pulley body 22 can be arranged to be fixedly connected to the wheel shaft 21 so that the two form an integral whole, and the pulley body 22 rotates with the relative rotation of the wheel shaft 21 and the wheel frame 10.

[0065] III. The wheel shaft 21 and the wheel frame 10 are arranged to be relatively rotatable, and the wheel shaft 21 and the pulley body 22 are arranged to be relatively rotatable.

[0066] It can be understood that, in order to keep the pulley body 22 and the wheel shaft 21 in a relatively stable cooperation state, the wheel shaft 21 and the pulley body 22 of the present embodiment are arranged to be radially relatively fixed, and the wheel shaft 21 is arranged to be movable in the lifting direction relative to the wheel frame 10. In this way, regardless of the specific embodiment described above, the pulley body 22 can also be adjusted in height by the relative movement of the wheel shaft 21 and the wheel frame 10 in the lifting direction while ensuring that the pulley body 22 can stably rotate, so that the structure of the clothes drying rod leveling mechanism is more reliable.

[0067] As a specific structural form of the wheel frame 10, the wheel frame 10 can be provided as a sheet metal part made of a metal material, has high strength and hardness, and can withstand a large pressure, so that it can normally support the weight of the entire pulley assembly 20 and withstand various forces during operation. Moreover, the sheet metal part is characterized by light weight and thin thickness, which greatly reduces the overall weight of the wheel frame 10 in the application of the lifting clothes hanger, thereby reducing the weight of the entire device, facilitating the handling and installation of the device, and when the lifting clothes hanger adopts the clothes hanger leveling mechanism, the mechanism does not occupy too much installation space of the lifting clothes hanger, making the product structure more integrated and compact.

[0068] Specifically, the wheel frame 10 includes a first support plate 11 and a second support plate 12, wherein the first support plate 11 and the second support plate 12 are spaced apart and oppositely arranged, and can be arranged substantially parallel to each other, so that a receiving space 13 is formed between the first support plate 11 and the second support plate 12, and the pulley assembly 20 is arranged in the receiving space 13 and is rotatably and movably connected with the first support plate 11 and the second support plate 12 along the lifting direction, so that the connection strength between the pulley assembly 20 and the wheel frame 10 is higher, which is beneficial to improve the stability of the pulley assembly 20 in the state of supporting the traction member 53.

[0069] It should be noted that in the application of the clothes drying machine, the pulley assembly 20 mainly bears the force from the traction member 53 from top to bottom, therefore, the rotation axis of the pulley assembly 20 is preferably substantially parallel to the horizontal plane, so as to ensure the stability of the pulley assembly 20 on the wheel frame 10, the first support plate 11 and the second support plate 12 are arranged substantially perpendicular to the horizontal plane and at the same horizontal height, and are spaced apart and oppositely arranged, so that the receiving space 13 is arranged along the lifting direction of the pulley assembly 20, and the two sides of the pulley assembly 20 can be matched with the wheel frame 10, at the same time, the receiving space 13 can provide sufficient lifting movement space for the pulley assembly 20, avoiding the interference between components and affecting the leveling effect of the clothes hanger 60.

[0070] Based on the above embodiment, further reference will be made to the accompanying drawings Figures 1-3 At least one of the first support plate 11 and the second support plate 12 is provided with a guide hole 14 extending along the lifting direction, and correspondingly, the pulley assembly 20 is provided with a guide portion 211 corresponding to the guide hole 14 and matching the structure of the guide hole 14, the guide portion 211 extends along the axial direction of the pulley assembly 20 and finally extends to the active matching state with the guide hole 14, so that the pulley assembly 20 is guided and matched with the wheel frame 10 through the guide portion 211 and the guide hole 14, realizing the effect of limiting the lifting movement stroke of the pulley assembly 20 by the wheel frame 10.

[0071] It should be noted that the guide holes 14 may be guide countersunk holes or guide through holes provided on the first support plate 11 and / or the second support plate 12 , and this embodiment does not impose strict limitations or requirements on this.

[0072] Taking the case where the guide hole 14 is opened in the first support plate 11 as an example, the opening of the guide hole 14 located on the first support plate 11 is set toward the second support plate 12, so that the guide portion 211 extending axially from the pulley assembly 20 located in the receiving space 13 can pass through the opening and enter the guide hole 14 corresponding to the first support plate 11; and in the case where the guide hole 14 is opened in the second support plate 12, the opening of the guide hole 14 located on the second support plate 12 is set toward the first support plate 11, so that the guide portion 211 extending axially from the pulley assembly 20 can pass through the opening and enter the guide hole 14 corresponding to the second support plate 12.

[0073] In one embodiment, in order to improve the cooperation stability between the pulley assembly 20 and the wheel frame 10, relative guide holes 14 are provided on the first support plate 11 and the second support plate 12, and guide parts 211 extending in opposite directions are correspondingly provided on the opposite sides of the pulley assembly 20. The pulley assembly 20 is guided and cooperated with the guide hole 14 provided in the first support plate 11 and the guide hole 14 provided in the second support plate 12 through the two guide parts 211, so that the position accuracy of the pulley assembly 20 during the lifting movement is higher, and the leveling effect of the clothes drying rod 60 is improved. At the same time, when the pulley assembly 20 is subjected to forces in different directions, the hole wall of the guide hole 14 can also constrain the pulley assembly 20 through the guide part 211, so that the pulley assembly 20 as a whole can be more stably supported by the wheel frame 10.

[0074] like Figures 1-3 As shown, in the embodiment in which the pulley assembly 20 includes a wheel axle 21 and a pulley body 22, the opposite ends of the wheel axle 21 can serve as guide portions 211 of the pulley assembly 20. By inserting the opposite ends of the wheel axle 21 into the respective guide holes 14 of the first support plate 11 and the second support plate 12, the guide holes 14 can constrain the movement direction of the wheel axle 21 through their hole walls, thereby ultimately limiting the lifting and lowering direction of the pulley body 22. The wheel axle 21 can not only constrain the steering direction of the pulley body 22, but also cooperate with the guide holes 14 to constrain the lifting and lowering direction of the pulley body 22, making the structure of the clothesline leveling mechanism simpler and more compact, saving production and assembly costs.

[0075] Of course, it is also understandable that, when only one of the first support plate 11 and the second support plate 12 is provided with the guide hole 14 , the pulley assembly 20 is only provided with the guide portion 211 on the side corresponding to the guide hole 14 .

[0076] Please continue to refer to the attached Figures 1-3 , continue to the above-mentioned wheel frame 10 including the first support plate 11 and the second support plate 12, the upper side and / or the lower side of the first support plate 11 is provided with the first adjusting plate 111, the first adjusting plate 111 is arranged at an angle with the first support plate 11, that is, in the case of arranging the first support plate 11 in a manner substantially perpendicular to the horizontal plane, the first adjusting plate 111 can be arranged parallel to the horizontal plane, or arranged at an acute angle or an obtuse angle with the first support plate 11, the first adjusting plate 111 provides a mounting position for the leveling component 30 of the wheel frame 10, so that the leveling component 30 can drive the pulley assembly 20 to move up and down when arranged on the first adjusting plate 111.

[0077] Correspondingly, the upper side and / or the lower side of the second support plate 12 is provided with the second adjusting plate 121, the second adjusting plate 121 is arranged at an angle with the second support plate 12, the second support plate 12 is provided with the leveling component 30, that is, in this embodiment, the first support plate 11 and the second support plate 12 are both provided with the leveling component 30, the leveling component 30 mounted on the first support plate 11 through the first adjusting plate 111 and the leveling component 30 mounted on the second support plate 12 through the second adjusting plate can respectively realize the driving of the pulley assembly 20 in the lifting direction on both sides, so that the pulley assembly 20 can keep stable during lifting, and from the above content, it can also be understood that the pulley assembly 20 is connected with the wheel frame 10 through the leveling component 30, therefore, the leveling component 30 is arranged as two, and the two leveling components 30 are respectively matched with the two ends of the pulley assembly 20, which can also ensure that the pulley assembly 20 keeps good matching relationship and stability with the wheel frame 10 in any state, and through the above-mentioned balancing of the gravity center of the pulley assembly 20, the load bearing capacity of the clothes drying rod 60 can also be improved.

[0078] For example, the first adjusting plate 111 is arranged on the upper side of the first support plate 11, and the leveling component 30 is correspondingly arranged on the upper side of the pulley assembly 20, in order to ensure that the leveling component can adjust the height position of the pulley assembly 20 on the wheel frame 10, the pulley assembly 20 needs to keep physical connection relationship with the leveling component 30, and it needs to be ensured that the pulley assembly 20 will not be separated from the leveling component 30 under the action of gravity. In the case that the first adjusting plate 111 is arranged on the lower side of the first support plate 11, the leveling component 30 is correspondingly arranged on the lower side of the pulley assembly 20, in this case, the leveling component 30 can be pressed against the leveling component 30 under the action of gravity, and this embodiment does not have strict limitation and requirement on the physical connection relationship between the two, and the pulley assembly 20 can always rely on gravity to keep linkage and cooperation with the leveling component 30.

[0079] In the case that the first adjusting plate 111 is arranged on the upper side and the lower side of the first support plate 11 (the second adjusting plate 121 is arranged on the upper side and the lower side of the second support plate 12), the user and the manufacturer can set the leveling component 30 on the corresponding first adjusting plate 111 according to their own and actual product needs, so that the universality of the clothesline leveling mechanism is improved, and the clothesline leveling mechanism can be adapted to different application scenarios and models.

[0080] Please refer to the accompanying drawings Figures 1-3 In an embodiment, the first support plate 11 and the second support plate 12 are further provided with a connecting plate 16, and the first support plate 11 and the second support plate 12 are connected by the connecting plate 16 to form a whole, so that the structural strength and integrity of the wheel frame 10 are improved, and the shaking of the first support plate 11 and the second support plate 12 under external force is reduced.

[0081] In other embodiments, one side of the first support plate 11 and the second support plate 12 can be respectively provided with a mounting plate 17 for mounting on the main support 50, and the mounting plate 17 needs to be arranged staggered with the first adjusting plate 111 and the second adjusting plate 121. For example, in the case that the first adjusting plate 111 and the second adjusting plate 121 are arranged on the upper side and the lower side of the wheel frame 10, the mounting plate 17 is arranged on the front side or the rear side of the first support plate 11 and / or the second support plate 12, and the mounting plate 17 is also arranged at an angle with the first support plate 11 and / or the second support plate 12 to provide a position for assembling the wheel frame 10 with other support structures.

[0082] It can be understood that the first adjusting plate 111, the second adjusting plate 121 and the mounting plate 17 are arranged at an angle with the first support plate 11 and the second support plate 12, which not only provides a stable mounting position for the leveling component 30 and the corresponding support structure, but also strengthens the structure of the wheel frame 10, which is similar to a reinforcing rib, so that the structure of the first support plate 11 and the second support plate 12 is more stable, the stability of the pulley assembly 20 on the wheel frame 10 is improved, and the bearing capacity of the clothesline 60 is improved.

[0083] Based on the above embodiment that the first adjusting plate 111 is arranged on the first support plate 11 and the second adjusting plate 121 is arranged on the second support plate 12, taking the leveling component 30 arranged as an adjusting bolt as an example, the first adjusting plate 111 and the second adjusting plate 121 are arranged on the upper side and the lower side of the first support plate 11 and the second support plate 12, respectively. Figures 1-3In the embodiment shown, in the embodiment in which the first adjusting plate 111 is provided with the leveling component 30, the first adjusting plate 111 is provided with a threaded hole 15 matched with the adjusting bolt, and in the embodiment in which the second adjusting plate 121 is provided with the leveling component 30, the second adjusting plate 121 is provided with a threaded hole 15 matched with the adjusting bolt, and the adjusting bolt is movably connected with the corresponding first adjusting plate 111 or second adjusting plate 121 by being screwed into the threaded hole 15. In this way, the adjusting bolt can rotate in the threaded hole 15 under the action of an external force, and move in the axial direction (the direction in which the threaded hole 15 is formed) of the threaded hole 15 according to the direction of rotation, so as to be further inserted into the threaded hole 15 or separated from the threaded hole 15, thereby cooperating with the pulley assembly 20 to enable the pulley assembly 20 to move correspondingly in the lifting direction. It can be understood that, in order to enable the movement of the adjusting bolt to realize the movement of the pulley assembly 20 in the lifting direction, the most direct way is to arrange the corresponding threaded hole 15 to extend in the lifting direction, so that the adjusting bolt can extend and retract in the threaded hole 15 in the lifting direction, thereby driving the pulley assembly 20 to move up and down.

[0084] It should be explained that, in the case that the leveling component 30 is movably connected with the pulley assembly 20, a corresponding threaded hole 15 can also be arranged on the pulley assembly 20 (the end of the wheel shaft 21) to realize the relative movement between the leveling component 30 and the pulley assembly 20 by rotating the adjusting bolt.

[0085] Specifically, the adjusting bolt includes a screw head 31 and a screw rod 32 connected with the screw head 31. In the above-mentioned embodiment in which the leveling component 30 includes an operation part and an adjusting part, the screw head 31 in this embodiment is the operation part of the leveling component 30, and the screw rod 32 is the adjusting part of the leveling component 30. The screw head 31, as the head of the adjusting bolt, is usually designed in various shapes (such as hexagonal, square, etc.) to facilitate rotation by using tools such as wrenches, screwdrivers, etc. The screw rod 32 is the main part of the adjusting bolt, and an external thread matched with the threaded hole 15 is arranged on the outer circumferential surface of the screw rod 32, so that the adjusting bolt can be screwed into the threaded hole 15 through the screw rod 32, and the extension and retraction of the adjusting bolt in the threaded hole 15 can be realized by operating the screw head 31. In the state that the adjusting bolt is connected with the first adjusting plate 111, the screw head 31 of the adjusting bolt is arranged on the side of the first adjusting plate 111 away from the pulley assembly 20, and in the state that the adjusting bolt is connected with the second adjusting plate 121, the screw head 31 of the adjusting bolt is arranged on the side of the second adjusting plate 121 away from the pulley assembly 20. In this way, the user can operate the screw head 31 of the adjusting bolt while providing greater design freedom between the adjusting bolt and the pulley assembly 20.

[0086] As an optional embodiment of any of the above-mentioned embodiments, a resilient member 40 is further arranged between the wheel frame 10 and the pulley assembly 20. It can be understood that the resilient member 40 is a functional part made of elastic material, which can be deformed under external force and restored to its original state after the external force is removed. It includes but is not limited to metal resilient members 40 (such as springs, spring sheets, elastic retaining rings, etc.) or non-metal resilient members 40 (such as rubber pads, plastic springs, etc.). The two ends of the resilient member 40 are respectively connected to the wheel frame 10 and the pulley assembly 20, and are used to continuously exert an elastic force in the upward direction on the pulley assembly 20, so that the pulley assembly 20 has a tendency to move upward.

[0087] Specifically, in the application of the clothes drying machine, the elastic force exerted by the resilient member 40 on the pulley assembly 20 is greater than the weight of the clothes drying rod 60 based on the connection to the wheel frame 10, that is, when the clothes drying rod 60 is hung with clothes, or the weight of the clothes hung on the clothes drying rod 60 does not reach a value sufficient to overcome the elastic force of the resilient member 40, the pulley assembly 20 will remain at a relatively high position in its lifting stroke under the action of the resilient member 40. In addition to ensuring that the clothes drying rod 60 can be further pulled closer to and abut against the main support 50 by the resilient member 40 when it is lifted to the main support 50, and ensuring that the clothes drying rod 60 as a whole forms a stable fit with the main support 50 in the storage state, it also allows the clothes drying rod 60 to make a downward movement through the connecting components such as the traction member 53 to trigger the travel switch arranged on the main support 50 at the low point of its lifting stroke, so that the control unit (control module 51) of the clothes drying machine (as described in the subsequent content) receives the switch signal from the travel switch and sends a signal that the clothes drying rod 60 is overloaded, thereby reminding the user to reduce the weight or amount of the hanging objects on the clothes drying rod 60.

[0088] In addition to this, the arrangement of the resilient member 40 between the wheel frame 10 and the pulley assembly 20 can also buffer and dampen the lifting and lowering movements of the pulley assembly 20, so that the pulley assembly 20 remains relatively stable with the wheel frame 10 during the drying of clothes on the clothes drying rod 60 or the lifting and lowering process, thereby avoiding the direct transmission of force between components and the loosening or even damage of the components, and prolonging the service life of the product.

[0089] From the above content, it can be understood that whether the leveling component 30 is arranged on the upper side or the lower side of the pulley assembly 20, the wheel frame 10 and the pulley assembly 20 can be connected through the resilient member 40, and only different types of resilient members 40 (such as tension springs or compression springs) need to be used.

[0090] Please refer to the accompanying drawings Figures 1-3In an embodiment in which the leveling component 30 is disposed above the pulley assembly 20 (via the first adjustment plate 111 or the second adjustment plate 121), the elastic member 40 may be disposed between the leveling component 30 and the pulley assembly 20, with both ends of the elastic member 40 fixedly connected to the leveling component 30 and the pulley assembly 20, respectively. It is understood that, since the elastic member 40 generally lacks freedom of movement other than in the directions of storing and releasing energy, in this embodiment, both ends of the elastic member 40 are fixed relative to the adjustment component and the pulley assembly 20, respectively, to prevent the elastic member 40 from transmitting the force acting on the adjustment component in the adjustment direction (e.g., the force acting in the rotational direction). Therefore, in this embodiment, the leveling component 30 and the wheel frame 10 are configured to be movably connected in the lifting direction, so that the movement of the pulley assembly 20 in the lifting direction is achieved through the relative movement of the leveling component 30 and the wheel frame 10. The leveling component 30 is lifted or released relative to the wheel frame 10, thereby lifting or releasing the pulley assembly 20 through the elastic member 40 to perform a corresponding lifting movement.

[0091] In the case where the above-mentioned leveling component 30 is set as an adjusting bolt, the screw head 31 of the adjusting bolt is located on the upper side of the first adjusting plate 111 and / or the second adjusting plate 121 (the side away from the elastic member 40), so that the relevant operator can operate the adjusting bolt and avoid interference between the elastic members 40 during the operation process.

[0092] like Figures 1-3 As shown, in the embodiment in which the above-mentioned pulley assembly 20 includes a wheel axle 21 and a pulley body 22, the wheel axle 21 is also guided and cooperated with the wheel frame 10, and the elastic member 40 is fixedly connected to the wheel axle 21, and the pulley body 22 is rotatably mounted on the wheel axle 21. Through this arrangement, it is possible to avoid the pulley body 22 from driving the wheel axle 21 to rotate relative to the wheel frame 10 when subjected to external force. In this way, the relative stillness of the wheel axle 21 is ensured, and the elastic member 40 and the wheel axle 21 can maintain a stable connection relationship. The elastic force applied by the elastic member 40 to the pulley assembly 20 remains stable, which has a good pre-tightening and buffering effect.

[0093] It can be understood that in the embodiment in which the above-mentioned wheel frame 10 includes a first support plate 11 and a second support plate 12, the guide holes 14 opened in the first support plate 11 and the second support plate 12 are respectively arranged to pass through the first support plate 11 and the second support plate 12, so that the opposite ends of the wheel axle 21 can pass through the outside of the first support plate 11 and the second support plate 12 through the guide holes 14 on both sides, so as to facilitate the connection between the wheel axle 21 and the elastic member 40, so that the structural layout of the clothesline leveling mechanism is more reasonable and compact.

[0094] like Figures 1-4As shown, the utility model also provides a clothes airing machine, this clothes airing machine is on the basis of using the clothes airing rod leveling mechanism provided by any one of above-mentioned embodiments, still include main support 50 and clothes airing rod 60.

Figure 4

[0095] Specifically, main support 50 is the support basis of the clothes airing machine, and a cavity opening downward accommodating cavity (not shown in the figure) is arranged in the inside of the main support 50, the accommodating cavity is used for accommodating the clothes airing rod 60 in the housing state, so that the clothes airing rod 60 does not protrude from the surface of the ceiling or the ceiling, and a rope passing opening (not shown in the figure) communicating with the accommodating cavity is formed in the upper side of the main support 50, and a control module 51 connected with the motor assembly 52 is arranged on the upper side of the main support 50, the control module 51 is used for sending a control signal to the motor assembly 52, a traction member 53 is arranged on the motor assembly 52 (power unit), in the embodiment that the traction member 53 is a flexible traction component such as a traction rope or a transmission belt, the hand shaker or the motor assembly 52 can control the traction member 53 to be wound or unwound by arranging a winding wheel, so that the motor assembly 52 controls the traction member 53 to release, contract or stop moving in the inside according to the control signal when receiving the control signal sent by the control module 51. The wheel carrier 10 in the clothes airing rod leveling mechanism is installed on the main support 50, and the clothes airing rod 60 is located below the main support 50, the traction member 53 changes the extension direction by being wound on the pulley assembly 20 on the basis of extending out of the motor assembly 52, and finally passes through the rope passing opening to realize the connection with the clothes airing rod 60, so that the motor assembly 52 drives the clothes airing rod 60 to move up and down relative to the main support 50 by controlling the extension and contraction of the traction member 53.

[0096] In an embodiment, a detachable protective cover 80 can also be arranged on the main support 50, the protective cover 80 covers the outside of the control module 51 and the motor assembly 52 to protect them.

[0097] ​It should be explained that in the case that the wheel frame 10 further comprises the mounting plate 17, the wheel frame 10 is mounted to the box support 70 through the mounting plate 17, the box support 70 is supported to the main support 50 and provides support to the wheel frame 10.

[0098] In summary, the clothes airing machine adopts the clothes airing rod leveling mechanism, so that the operator needs to adjust the levelness of the clothes airing rod 60 without disassembling the whole device, and the operator only needs to adjust the leveling component 30 installed between the wheel frame 10 and the pulley assembly 20, so that the height position of the clothes airing rod 60 corresponding to the traction member 53 is adjusted according to the height position of the pulley assembly 20 on the wheel frame 10, the operation process is simple and convenient, the height position of the clothes airing rod 60 can be observed in real time according to the change of the pulley assembly 20, the levelness adjustment of the clothes airing rod 60 is more accurate, and the adjustment requirement in different situations is met.
