[0028] The utility model provides an aircraft air-conditioning duct retracting and deploying device, as shown in Figure 1 , 2 , 3, 4, and 5. It includes a fixed bracket 10, on which a rotating connection part is provided. The rotating connection part is rotatably connected to the jet bridge. On the fixed bracket 10, a first rotation driving part 30 is provided, and the first rotation driving part 30 can drive the fixed bracket 10 to rotate relative to the jet bridge; a winding drum 40 is rotatably arranged inside the fixed bracket 10. The winding drum 40 is a cylinder with one end open and the other end sealed. An air outlet 41 communicating with the inner cavity of the winding drum 40 is opened on the cylinder body of the winding drum 40. An air-conditioning duct is wound on the winding drum 40. The air-conditioning duct has an air inlet end and an air outlet end. The air inlet end of the air-conditioning duct is connected to the air outlet 41; a second rotation driving part 50 is arranged inside the inner cavity of the winding drum 40, and the second rotation driving part 50 can drive the winding drum 40 to rotate.

[0029] This aircraft air-conditioning duct retracting and deploying device is installed on the jet bridge and rotatably installed on the jet bridge through the rotating connection part. Specifically, the rotating connection part is a jet bridge rotating bearing 20. One side of the jet bridge rotating bearing 20 is connected to the jet bridge, and the other side is connected to the fixed bracket 10. This aircraft air-conditioning duct retracting and deploying device moves with the jet bridge without the need for ground personnel to push or move it; when in use, connect the airport duct to the open end of the winding drum 40, start the second rotation driving part 50 to drive the winding drum 40 to rotate, and unwind the air-conditioning duct wound on the winding drum 40. After unwinding to an appropriate length, connect the air outlet end of the air-conditioning duct to the aircraft air-conditioning interface. The air-conditioning air from the airport duct enters the inner cavity of the winding drum 40 through the end opening of the winding drum 40, then enters the air-conditioning duct through the air outlet 41 of the winding drum 40 and the air inlet end of the air-conditioning duct, and is then conveyed to the aircraft air-conditioning interface along the air inlet end of the air-conditioning duct; when the aircraft does not need to supply air-conditioning air, remove the air outlet end of the air-conditioning duct, and then start the second rotation driving part 50 to drive the winding drum 40 to rotate, so that the air-conditioning duct is wound on the winding drum 40, realizing automatic unwinding and automatic winding; when in use, the first rotation driving part 30 can be started to drive the fixed bracket 10 to rotate, and the winding drum 40 and the air-conditioning duct will rotate accordingly to adjust the unwinding and winding directions. In addition, the second rotation driving part 50 is built inside the inner cavity of the winding drum 40. On the one hand, it protects the second rotation driving part 50 from being damaged by external collisions, and on the other hand, it facilitates the rotation of the fixed bracket 10. There are no external components on the periphery of the fixed bracket 10, and it can rotate 360°. The technical solution of the utility model greatly reduces the workload of ground personnel and improves work efficiency.

[0030] In some embodiments of the present utility model, as shown in Figure 1 , 2, as shown in FIGS. 3, a forward extension frame group is provided on the fixed bracket 10, and a deviation rectifying wheel group is provided on the forward extension frame group. When the air-conditioning duct is unwound from or wound onto the reel 40, it is clamped between the deviation rectifying wheel groups. The deviation rectifying wheel groups guide and correct the deviation when the air-conditioning duct is unwound and wound. Especially when winding, the deviation rectification can prevent the air-conditioning duct from winding to one side of the reel 40. Specifically, the forward extension frame group includes a forward extension lower frame 60 and a forward extension upper frame 70. The deviation rectifying wheel group includes deviation rectifying wheels 80 respectively arranged on the forward extension lower frame 60 and the forward extension upper frame 70. A rolling space for the air-conditioning duct to pass through is formed between the deviation rectifying wheels 80 on the forward extension lower frame 60 and the forward extension upper frame 70. The air-conditioning duct is clamped between the deviation rectifying wheels 80 on the forward extension lower frame 60 and the forward extension upper frame 70, and the deviation rectifying wheels 80 play a role in guiding and assisting the rolling and winding.

[0031] Since deviation rectification is not required during unwinding, the forward extension upper frame 70 can also be lifted. During winding, the forward extension upper frame 70 is lowered. In some embodiments of the present invention, such as Figure 1 , 2 , as shown in FIGS. 3, the forward extension upper frame 70 is rotatably connected to the fixed bracket 10; a support arm cylinder 90 is provided on the fixed bracket 10. The support arm cylinder 90 is connected to the forward extension upper frame 70 and controls the lifting or lowering of the forward extension upper frame 70 to make it away from or close to the forward extension lower frame 60.

[0032] In some embodiments of the present invention, a bracket rotating bearing is provided on the side of the fixed bracket 10. The outer side of the bracket rotating bearing is connected to the fixed bracket 10, and its inner side rotates with the reel 40, so that the reel 40 can rotate relative to the fixed bracket 10.

[0033] In some embodiments of the present invention, such as Figure 4 , 5 shown, an inner cylinder 100 is provided inside the reel 40, and the second rotation driving part 50 is arranged on the inner cylinder 100 and connected to the reel 40.

[0034] According to an aircraft air-conditioning duct winding and unwinding device according to an embodiment of the present invention, as Figure 1 , 2 , 3, 4, 5 shown, runners 110 are provided at both ends of the reel 40. The reel 40 can also be rotated by rotating the runners 110 to realize manual unwinding and winding.
