For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] See also Figure 2 and Figure 3The present embodiment provides a self-balancing clothes drying machine, including a main machine, a clothes drying rod and a balancing device 500. The two ends of the main machine are respectively connected with a scissor device and a traction rope 400. The clothes drying rod is arranged below the main machine. The balancing device 500 is connected with the scissor device, and the balancing device 500 includes a transmission structure 530 and an adjustment structure 520, the bottom of the adjustment structure 520 is connected with the clothes drying rod, the adjustment structure 520 is in transmission connection with the transmission structure 530, the traction rope 400 is connected with the transmission structure 530, and a counterweight block 540 is arranged on the transmission structure 530.

[0037] The self-balancing clothes drying machine is provided with a balancing device 500 on the clothes drying rod, and the lower ends of the scissor devices are connected to the balancing device 500. The clothes drying rod is connected to the adjustment structure 520. When clothes are hung on the clothes drying rod, the force of the clothes drying rod will be transmitted to the adjustment structure 520. When the load on one side of the clothes drying rod is greater than that on the other side, the adjustment structure 520 with a larger load drives the transmission structure 530 to move, so that the counterweight block 540 moves toward the direction close to the small load end, so that the balancing device can be kept in a horizontal position, and the scissor device is always in a vertical state, so as to prevent the clothes drying rod from tilting greatly to one side, thereby preventing the scissor device from being deformed or damaged.

[0038] Further, the balancing device 500 further includes a crossbeam 510, the crossbeam 510 is connected to the scissor-type device, and the transmission structure 530 and the adjustment structure 520 are both arranged on the crossbeam 510. The crossbeam 510 supports the transmission structure 530 and the adjustment structure 520. Optionally, the bottom of the scissor-type device is connected to the crossbeam 510.

[0039] Furthermore, the transmission structure 530 includes a transmission belt 532, and an adjustment structure 520 is respectively arranged on both sides of the transmission belt 532. The transmission belt 532 includes a first section and a second section. The traction rope is connected to the first section of the transmission belt 532, and the counterweight 540 is arranged in the second section of the transmission belt 532. When the load on one side of the clothes drying rod is greater than that on the other side, the adjustment structure 520 with a larger load drives the transmission belt 532 to move, and at the same time, the connection point of the traction rope 400 and the transmission belt 532 moves toward the direction close to the large load end. Therefore, with the connection point of the traction rope 400 and the transmission belt 532 as the center point, the torque at the large load end is equal to the torque at the small load end, so that the balancing device can be kept in a horizontal position to prevent the scissor-type device from tilting.

[0040] Further, see Figure 2 The adjustment structure 520 includes a support 521 movably arranged in the vertical direction on the beam 510, a transmission part 522 is arranged on the top of the support 521, the transmission part 522 is connected to the transmission belt 532, and the bottom of the support 521 is connected to the clothes drying rod.

[0041] It can be understood that when the load on one side is greater than that on the other side, the support 521 at the large load end will move downward in the vertical direction, and then the transmission part 522 can drive the transmission belt 532 to rotate; when the load is unloaded, the support 512 will return to its original position, and at the same time, the transmission part 522 drives the transmission belt 532 back to its original position, and then the mounting block 540 and the connection point between the traction rope 400 and the transmission belt 532 return to their original positions.

[0042] See also Figure 3 When the two adjustment structures 520 are loaded with the same load or are unloaded, the traction rope 400 is located in the middle of the first section of the transmission belt 532, and the counterweight 540 is located in the middle of the second section of the transmission belt 532. In this embodiment, the number of the counterweight 540 is one, and in other embodiments, the number of the counterweight 540 can be two, three, or other numbers, as long as the two ends of the beam 510 are unloaded and the beam 510 is kept in a horizontal position.

[0043] Alternatively, see Figure 4 The support 521 is a cylindrical rod-shaped structure, and a round hole is provided on the crossbeam 510, and the support 521 is inserted into the round hole. Optionally, the cross-sectional area of ​​the transmission part 522 is larger than the area of ​​the round hole, so that the transmission part 522 cannot pass through the round hole and move downward, thereby preventing the support 512 from falling from the round hole, thereby causing the clothes drying rod to fall.

[0044] Further, see Figure 4 , an anti-dropout portion 523 is provided at the bottom of the pillar 521, a spring 524 is sleeved on the pillar 521, the pillar 521 is vertically penetrated through the crossbeam 510, and the spring 524 is located between the crossbeam 510 and the anti-dropout portion 523. It can be understood that the transmission portion 522 is located above the crossbeam 510, and the spring 524 is located below the crossbeam 510. The anti-dropout portion 523 can prevent the spring 524 from falling off the pillar 521. By providing the spring 524, when the load is unloaded, the spring 524 can return the pillar 521 to its original position, thereby restoring the transmission structure 530 to its original position.

[0045] Optionally, the bottom end of the spring 524 abuts against the anti-slip portion 523, and the top end abuts against the crossbeam 510, so that when Figure 3 When the support column 521 at the left end is loaded with a large load, the spring 524 is stretched, and the support column 521 moves downward, and the transmission part 522 drives the transmission belt 532 to rotate counterclockwise, so that the counterweight 540 is away from the large load end (left end), and the connection point between the traction rope 400 and the transmission belt 532 is close to the large load end. Similarly, when the support column 521 at the right end is loaded with a large load, the spring 524 is stretched, and the support column 521 moves downward, and the transmission part 522 drives the transmission belt 532 to rotate clockwise, so that the counterweight 540 is away from the large load end (right end), and the connection point between the traction rope 400 and the transmission belt 532 is close to the large load end.

[0046] See also Figure 4 In this embodiment, the transmission part 522 is a rack arranged in the vertical direction, and the rack is fixedly connected to the pillar 521. When the pillar 521 moves up and down, it drives the rack to move up and down. The adjustment structure 520 also includes a transmission member 525, which is connected to the transmission part 522 in a transmission manner, and the transmission member 525 can drive the transmission belt 532 to rotate. Optionally, the transmission member 525 is a gear. It can be understood that the rack and the gear are meshed for transmission. In other embodiments, the transmission part 522 and the transmission member 525 can be other components that can achieve transmission connection.

[0047] Furthermore, the adjustment structure 520 further includes a support seat 526 disposed on the crossbeam 510, and the transmission member 525 is mounted on the support seat 526. The support seat 526 plays a supporting role for the gear.

[0048] Further, the support seat 526 includes a support rod 5261 and a connecting shaft 5262, the support rod 5261 is connected to the cross beam 510, the transmission member 525 is fixedly connected to the connecting shaft 5262, and the connecting shaft 5262 is rotatably connected to the support rod 5261. When the rack drives the gear to rotate, the connecting shaft 5262 rotates around its central axis.

[0049] Furthermore, the transmission structure 530 includes two transmission wheels 531, and the transmission belt 532 is sleeved on the two transmission wheels 531. The transmission wheel 531 and the transmission member 525 located at the same end of the beam 510 rotate coaxially through the connecting shaft 5262, that is, the transmission wheel 531 and the transmission member 525 located at the same end of the beam 510 are both connected to the same connecting shaft 5262. Therefore, when the transmission member 525 rotates, the rotating wheel rotates synchronously, thereby driving the transmission belt 532 to rotate.

[0050] In this embodiment, there are two support rods 5261, and the transmission member 525 is located between the two support rods 5261. In other embodiments, there may be one support rod 5261, and the gear and the transmission wheel 531 are respectively located on both sides of the support rod 5261. Of course, there may also be three support rods 5261, and there are two intervals between the three support rods 5261, and the gear and the transmission wheel 531 are respectively arranged in one interval.

[0051] See also Figure 5 The support seats 526 at both ends are connected by a connecting rod 550 to increase the stability of the overall structure. The connection structure between the scissor device and the connecting rod 550 is a mature technical means in the art, and will not be described in detail here.

[0052] See also Figure 2 Taking the case where the load on the left side is larger as an example, the working principle of the self-balancing clothes drying machine provided by this embodiment is described:

[0053] When the left end support 521 is loaded with a large load, the spring 524 is stretched, and the support 521 moves downward, the rack drives the gear to rotate counterclockwise, and then the gear drives the transmission wheel 531 to rotate counterclockwise, so that the transmission belt 532 rotates counterclockwise, and then the counterweight 540 is away from the large load end (left end), and the connection point of the traction rope 400 and the transmission belt 532 is close to the large load end. With the connection point of the traction rope 400 and the transmission belt 532 as the center point, the torque of the large load end is equal to the torque of the small load end, so the crossbeam 510 remains in a horizontal position, and the scissor-fork device is always in a vertical state. When the left end is unloaded, the spring 524 contracts, the counterweight 540 and the traction rope 400 return to their original positions, and the crossbeam 510 is still in a horizontal position.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
