[0002] During the use of central air conditioning, in order to guide the air flow and adjust the temperature distribution, an air guide plate is usually used to control the air outlet direction of the air conditioner, avoid direct blowing, improve the comfort of indoor air flow, and help deliver cold or heated air evenly to every corner.

[0003] According to a Chinese patent document with announcement number CN220624344U, an air guide plate of a central air conditioner comprises an air guide plate assembly, wherein the air guide plate assembly is installed at the air outlet of the central air conditioner through a support seat, and a pull rope adjustment assembly is installed between the air guide plate assembly and the support seat, and the pull rope adjustment assembly comprises: a pull rope seat fixedly connected to the outer wall of the support seat; a winding wheel rotatably connected to the inside of the pull rope seat; a bearing seat arranged at both ends of the winding wheel; a transmission box installed on the top of the pull rope seat; by setting the pull rope adjustment assembly, the angle of the air guide plate is adjusted by adjusting the length of the pull rope, so that the angle of the air guide plate can be easily adjusted when in use, and at the same time, after the adjustment is completed, the pull rope supports the plate body and bears force, and the angle adjustment seat between the air guide plate and the bracket only provides supporting force, so that the air guide plate can stably maintain the adjusted angle, and at the same time, the air guide plate has a longer service life.

[0004] Based on the search of the above patents and in combination with the guide plate in the prior art, it is found that when the above guide plate is in use, the length of the pull rope is adjusted by using the pull rope adjustment assembly, thereby adjusting the use angle of the guide plate, and supporting the guide plate with the help of the pull rope. However, in the actual use process, due to the long-term use of the air conditioner, the continuous blowing of hot air and cool air will cause stretching, thermal expansion and contraction, which will change the structure of the pull rope, thereby affecting the toughness of the pull rope and making it impossible to support the guide plate. Long-term use may cause the pull rope to age and thus wear out, affecting the normal adjustment and use of the guide plate, thereby reducing its practicality. Utility Model Content
