[0035] In the present invention, the terms "first", "second", etc. are used to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Embodiment 1:

[0037] like Figure 1-4 As shown, a clothes drying rack includes a main unit 100, a linkage type drying rod assembly 200 arranged in parallel under the main unit 100, and a lifting device 300 connecting the main unit 100 and the linkage type drying rod assembly 200. The lifting device 300 includes a traction mechanism and a balance connection mechanism, wherein the traction mechanism is a steel wire rope, and the lifting and lowering functions of the linkage type drying rod assembly 200 are realized by the motor retracting and releasing the steel wire rope. The balance connection mechanism is an X-shaped telescopic assembly, which can be folded or lowered as the linkage type drying rod assembly 200 rises or falls, thereby playing a balancing and supporting role for the clothes drying rack.

[0038] like Figure 1-4As shown, the linkage type drying rod assembly 200 includes a clothes drying rod assembly 10 and two quilt drying rods 20, wherein the clothes drying rod assembly 10 is connected to the lifting device 300, each quilt drying rod 20 is connected to the clothes drying rod assembly 10 through at least one connecting arm 30, and a synchronous linkage assembly 40 is provided between two adjacent connecting arms 30 on the two quilt drying rods 20 to realize synchronous movement of the two quilt drying rods 20; the quilt drying rods 20 in the use state are located below the clothes drying rod assembly 10; when the user needs to store the quilt drying rods 20, the two quilt drying rods 20 are synchronously lifted from the low position in the use state to the high position in the storage state.

[0039] like Figure 5-8 As shown, one end of each link arm 30 is movably connected to the clothes drying rod assembly 10, and the synchronous linkage assembly 40 is arranged at the same side end of two adjacent link arms 30. In this embodiment, it is the upper end of the first link arm 30a and the second link arm 30b.

[0040] Furthermore, the clothes-drying rod assembly 10 includes two clothes-drying rods arranged in parallel and end connecting rods 50 at both ends. The first connecting arm 30a is axially connected to the end connecting rod 50 through the first rotating shaft 31a, and the second connecting arm 30b is axially connected to the end connecting rod 50 through the second rotating shaft 31b. The first connecting arm 30a and the second connecting arm 30b can rotate around the axis joint through the synchronous linkage assembly 40, so that the free ends of the connecting arms 30 can move up and down.

[0041] Furthermore, in the use state, the connecting arm 30 is in a vertical state and the quilt drying rod 20 is located at the lower end of the connecting arm 30; in the storage state, the connecting arm 30 is in a horizontal state.

[0042] Compared with the traditional structure in which two quilt drying rods are independent of each other, during actual use, due to the linkage effect of the synchronous linkage component 40 on the two connecting arms 30, the user only needs to pull down or push up one side of the quilt drying rod 20 to simultaneously unfold and fold the two quilt drying rods 20, thereby improving the convenience of using the clothes drying machine.

[0043] like Figure 5-8 As shown, in this embodiment, the synchronous linkage assembly 40 is a gear linkage assembly, which realizes the synchronous movement of the two connecting arms 30 through mutual transmission between gears.

[0044] Preferably, each quilt drying rod 20 is connected to both ends of the clothes drying rod assembly 10 through two symmetrical connecting arms 30. The clothes drying rod assembly 10 includes an end connecting rod 50, a gear linkage assembly is arranged on the end connecting rod 50, and the gear linkage assembly is simultaneously connected to the upper ends of the two connecting arms 30, and the two connecting arms 30 are synchronously rotated through the gear linkage assembly.

[0045] like Figure 7As shown, the gear linkage assembly includes two transmission gears 32 and two link arm gears 33, namely, a first transmission gear 32a, a second transmission gear 32b, a first link arm gear 33a and a second link arm gear 33b. The first transmission gear 32a and the second transmission gear 32b are symmetrically arranged at the middle position of the end link rod 50, and the first transmission gear 32a and the second transmission gear 32b are meshed with each other. The first link arm gear 33a and the second link arm gear 33b are respectively arranged on both sides of the first transmission gear 32a and the second transmission gear 32b, the first transmission gear 32a is meshed with the first link arm gear 33a, and the second transmission gear 32b is meshed with the second link arm gear 33b. The first link arm gear 33a is connected to the upper end of the first link arm 30a through the first rotating shaft 31a, and the second link arm gear 33b is connected to the upper end of the second link arm 30b through the second rotating shaft 31b.

[0046] When the user pulls the link arm 30 on one side, the link arm gear 33 at the end of the link arm 30 drives the transmission gear 32 on the same side to rotate in the opposite direction. The two adjacent transmission gears rotate in the opposite direction, and the transmission gear on the other side rotates in the opposite direction to the link arm gear to drive the link arm on the other side to rotate, thereby realizing the synchronization function of the quilt drying rod 20.

[0047] Further preferably, the first transmission gear 32a and the second transmission gear 32b are centrally positioned and axially connected to the middle connection hole of the end link 50 through a semi-hollow rivet, so that they can rotate around the semi-hollow rivet. Two fixing brackets 34 are symmetrically arranged on the end link 50 on both sides of the first transmission gear 32a and the second transmission gear 32b, and the positions of the fixing brackets 34 match the first link arm gear 33a and the second link arm gear 33b.

[0048] like Figure 8-9 As shown, the fixing frame 34 is formed by symmetrical sheet metal bending to form a folding portion 1 and two opposite inverted L-shaped side walls 2. The inverted L-shaped side wall 2 includes a transverse portion 21 located at the upper part and a vertical portion 22 at the lower part, and the folding portion 1 is connected to the outer ends of the two transverse portions 21. Among them, the outer end of the transverse portion 21 is fixed to the end connecting rod 50 by a semi-hollow rivet, and the lower end of the vertical portion 22 is connected to the connecting arm gear 33 and the connecting arm 30. Specifically, the first connecting arm gear 33a or the second connecting arm gear 33b is arranged in the fixing frame 34, and the first rotating shaft 31a or the second rotating shaft 31b passes through the corresponding connecting arm 30, the shaft hole of the vertical portion 22 and the gear inner hole of the first connecting arm gear 33a or the second connecting arm gear 33b in sequence to be connected to the end connecting rod 50.

[0049] Preferably, the first link arm gear 33a and the second link arm gear 33b are both 90-degree sector gears, and the link arm gear 33 rotates with the transmission gear 32, so that the first link arm 30a and the second link arm 30b can rotate with the first link arm gear 33a and the second link arm gear 33b to move from a vertical position to a horizontal position. In the use state, the link arm 30 is in a vertical state and the quilt drying rod 20 is located at the lower end of the link arm 30; in the storage state, the link arm 30 is in a horizontal state.

[0050] Further preferably, a protective cover 35 is also provided on the outside of the gear linkage assembly, which not only prevents the gear linkage assembly from being exposed and easily rusting, but also makes the entire linkage drying rod assembly 200 neat and beautiful in appearance.

[0051] Furthermore, preferably, Figure 10-11 As shown, the clothes-drying rod assembly 10 includes two end seats 60 bridging the clothes-drying rods on both sides, a traction mechanism and a balancing connection mechanism are connected to the end seats 60, a slot 61 is provided on the lower side of the end seat 60, the slot 61 has an opening that can be inserted into the horizontally placed link arm 30, and elastic clamping portions 62 are provided on both sides of the slot 61. The elastic deformation of the elastic clamping portions 62 can be used to position the quilt-drying rod 20 in the slot 61.

[0052] It should be understood that, in addition to the above-mentioned gear linkage assembly, the synchronous linkage assembly 40 can also be a connecting rod linkage assembly.

[0053] More preferably, if Figure 1 , 3 As shown, in this embodiment, the clothes-drying rod assembly and the quilt-drying rod are both telescopic structures, and both the clothes-drying rod assembly and the quilt-drying rod include a main rod 001 and extension rods 002 sleeved at both ends, and the extension rods 002 can be telescopic relative to the corresponding main rod 001. Preferably, the corresponding main rods 001 and extension rods 002 of the clothes-drying rod assembly 10 and the quilt-drying rod 20 are of equal length and aligned up and down, so that the clothes-drying rod assembly and the quilt-drying rod can be telescopic synchronously.

[0054] Further preferably, a clothes drying component 003 having clothes drying holes A is provided below the main rod 001 of the clothes drying rod assembly to facilitate users to dry clothes.

[0055] During actual use, the user pulls the quilt drying rod 20 downward from the notch of the end seat 60 until the movable shaft moves to the lowermost end of the slide rail. At this time, the quilt drying rod 20 can be used for drying, which conveniently expands the longitudinal drying space.

[0056] When large items need to be dried, the user can pull the quilt drying rod outward, and simultaneously pull out the clothes drying rod assembly and the extension rod 002 of the quilt drying rod 20, thereby expanding the horizontal drying area.

[0057] Embodiment 2:

[0058] The structure of the clothes drying machine in this embodiment is substantially the same as that in the first embodiment, and only the differences are described below.

[0059] like Figure 1-2 As shown, in this embodiment, the linked clothes-drying rod assembly 200" includes a clothes-drying rod assembly 10" and two quilt-drying rods 20". The clothes-drying rod assembly 10" further includes two parallel clothes-drying rods 101". Preferably, the clothes-drying rod 101" and the quilt-drying rod 20" are both telescopic structures as described in the first embodiment.

[0060] At least one of the two quilt drying rods 20" is connected to the clothes drying rod assembly 10" through two cross arms 30" that cross each other to form an X. One end of the two cross arms 30" is symmetrically hinged to the end of the clothes drying rod 101", and the other end is axially connected to the quilt drying rod 20".

[0061] Preferably, a pair of connecting arms 30" is provided at each end along the length direction of the clothes drying rod assembly 10".

[0062] like Figure 3-4 As shown, each link arm 30" is provided with a slide rail 01" extending along its length direction, and the two link arms 30" are connected by a movable shaft 02", which passes through the slide rails 01" of the two link arms 30" at the same time and can slide in the slide rails 01". In order to make the two link arms 30" move synchronously, a synchronous linkage component 40" is provided between the two cross-X link arms 30".

[0063] Specifically, the synchronous linkage assembly 40" includes a linear rack 03" disposed in each slide rail 01" and rolling gears 04" disposed at both ends of the movable shaft 02" and cooperating with the linear rack 03".

[0064] Preferably, the connecting arm 30" includes an inner plate 05" and an outer cover 06", the outer cover 06" is adapted to the inner plate 05", and the outer cover 06" is snapped onto one side of the inner plate 05" facing outward. The slide rail 01" is a strip-shaped through hole groove that passes through the inner plate 05" and the outer cover 06". The linear rack 03" is installed in the cavity formed by the outer cover 06" and the inner plate 05", and is fixed on the inner side of the outer cover 06", and corresponds to the position of the slide rail 01". The linear rack 03" is set on one side along the direction of the slide rail 01", and its tooth groove faces the inside of the slide rail 01". The movable shaft 02" passes through two rolling gears 04", and the rolling gears 04" are coaxially fixed on both sides of the movable shaft 02".

[0065] It should be understood that the movable shaft 02" passes through the two connecting arms 30" in sequence, and the two outer ends have shaft caps with a diameter greater than the width of the slide rail 01", thereby limiting the slippage of the two connecting arms 30" in the thickness direction. The rolling gear 04" on the movable shaft 02" is meshed with the linear rack 03" and when the position of the quilt drying rod 20" relative to the clothes drying rod assembly 10" changes, the rolling gear 04" on the movable shaft 02" rolls along the linear rack 03" of the connecting arm 30". The synchronous linkage mechanism synchronizes the movement of the movable shaft 02" on the two connecting arms 30", ensures the synchronization of the activities of the quilt drying rods 20" on both sides, improves the stability of the quilt drying rod 20" during the folding or unfolding process, and further improves the convenience of folding or unfolding the quilt drying rod 20".

[0066] Preferably, in the use state, the movable shaft 02" moves to the lowermost end of the slide rail 01", and the quilt drying rod 20" is suspended below the clothes drying rod assembly 10". Preferably, the lowermost end of the slide rail 01" is located below the center of the connecting arm 30", so that in the use state, the two quilt drying rods 20" are laterally offset on the inner side of the clothes drying rod assembly 10".

[0067] In the storage state, the movable shaft 02" moves to the uppermost end of the slide rail 01", and the quilt drying rod 20" is in a horizontal state and is positioned on the end seat 60" of the clothes drying rod assembly 10", which does not take up extra space and maintains the overall aesthetics of the clothes drying machine.

[0068] The above is a detailed introduction to the linkage drying rod assembly and clothes drying machine provided by the present invention. The principles and implementation methods of the present invention are described in detail using specific examples. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
