[0022] A pull-cord adjustment mechanism is provided inside the fixed box 2, and the pull-cord adjustment mechanism includes a sleeve 13. The interior of the sleeve 13 is elastically connected to a slide plate 11 through a limit spring 12. The outer side of the slide plate 11 is slidably connected to the inner side of the sleeve 13. The sleeve 13 serves to increase the sliding stability of the slide plate 11. A sliding hole slidably connected to the upper end of the worm gear 2 9 is provided at the bottom of the sleeve 13. Two groups of rotating holes are provided at the ends close to each other of the air-conditioning body 1 and the fixed box 2. One group of rotating holes is rotatably connected to the worm gear 4, and the other group of rotating holes is rotatably connected to the rotating rod 6. The rotation of the worm gear 4 and the rotating rod 6 inside the air-conditioning body 1 and the fixed box 2 is realized through the rotating holes.
[0023] Two ratchets 14 are fixedly installed on the outside of the rotating rod 6 located inside the fixed box 2. The gears on the outside of the two ratchets 14 are in opposite directions. The outsides of the two ratchets 14 are slidably engaged with symmetrical pawls 15. The lower ends of the two pawls 15 are rotatably connected to the inner wall of the fixed box 2. Through the two pawls 15 with opposite gears and symmetrical pawls 15, the rotating rod 6 is limited to rotate in the forward and reverse directions.
[0024] A hinge block 16 is rotatably installed on the upper end of one pawl 15, and a connecting rod 17 is rotatably installed on the end of the hinge block 16 away from the pawl 15. The connecting rod 17 is fixedly connected to the outer side of the pull rod 8. When the pull rod 8 slides downward, one pawl 15 is driven by the connecting rod 17 and the hinge block 16 to release the positive rotation limit. A fixing plate 18 is provided at the bottom of the other pawl 15. The fixing plate 18 is installed on the inner wall of the fixing box 2. The top of the fixing plate 18 and the lower end of the other pawl 15 are elastically connected by a spring sheet 19. The other pawl 15 plays a role in limiting the reverse rotation of the rotating rod 6. When rotating forward, the other pawl 15 is slidably connected to the tooth surface of the other ratchet 14.
[0025] A worm 29 is rotatably installed at the bottom of the skateboard 11, and a worm wheel 10 is provided on the outer fixed sleeve of the worm 29. A pull rod 8 is rotatably installed at the bottom of the worm 29, and a pull rope 3 is installed at the bottom of the pull rod 8. A through hole matching the size of the pull rope 3 is provided at the bottom of the fixed box 2. The pull rope 3 extends out of the bottom of the fixed box 2, which is convenient for the user to pull the pull rope 3. The worm wheel 10 is slidably engaged with one end of the worm 14. A worm wheel 20 is installed at one end of the rotating rod 6 extending into the interior of the fixed box 2. The worm wheel 20 is slidably engaged with the worm 29. When the pull rope 3 is not subjected to force, the worm wheel 10 does not contact one end of the worm 4, and the worm wheel 20 does not contact the worm 29. When the pull rope 3 is subjected to force, the worm wheel 10 is engaged with one end of the worm 4, and the worm wheel 20 is engaged with the worm 29. At this time, the fan blades 5 rotate and the shutters 7 rotate synchronously.
[0026] Working principle: When in use, the fan blade 5 rotates under the influence of wind force, driving the worm 14 to rotate forward. When the rotation angle of the blinds 7 needs to be adjusted, the pull rope 3 is pulled downward, and the pull rope 3 drives the pull rod 8, the worm 2 9, the worm wheel 10 and the slide plate 11 to slide downward. The slide plate 11 stretches the limit spring 12, and the pull rod 8 drives one of the ratchet pawls 15 to disengage from the ratchet wheel 14 through the connecting rod 17 and the hinge block 16, releasing the limit of the forward rotation of the rotating rod 6. At this time, the worm wheel 10 is meshed with the worm 14, the worm 2 9 is meshed with the worm wheel 20, and the worm 14 drives the worm wheel 10 to mesh with the worm 14. Wheel 10 rotates, worm wheel 10 drives worm gear 2 9 to rotate, worm gear 2 9 drives worm wheel 2 20 to rotate forward, worm gear 2 20 drives rotating rod 6 to rotate forward, rotating rod 6 drives shutter 7 to rotate forward to adjust the angle, after adjusting to the required angle, pull rope 3 is released, and the resilience of limit spring 12 drives pull rod 8, worm gear 2 9, worm wheel 10 and slide plate 11 to slide upward, worm wheel 10 is not meshed with worm gear 1 4, worm gear 2 9 is not meshed with worm wheel 20, one of the ratchet pawls 15 is meshed with ratchet wheel 14, and at this time, rotating rod 6 rotates forward and reverse to limit.
