  • the bottom wall of the mounting groove 6 may be flush with an edge on the right side of the notch 65. In this way, a width of the notch 65 along the length direction of the middle frame 1 is equal to a distance from the first connecting member 651 to the bottom wall of the mounting groove 6. After contacting a bottom surface of the mounting groove 6, the mounting frame 35 may slide along the bottom surface of the mounting groove 6, so that the mounting frame 35 is inserted into the notch 65.
  • the driving wheel 31 and the outer guide rotating shaft 21 are connected by using the latch assembly 4 as both a connecting member and a transmission member, so that the three can rotate synchronously, which improves the coaxial accuracy.
  • the structural design of the latch assembly 4 can simplify the mounting steps of the whole device, improve the mounting efficiency, reduce the labor cost and time cost, and can avoid damage to parts and components while ensuring the long-distance transmission effect.
  • the mounting groove 6 is formed in the end portion of the middle frame 1, the driving box 32 is then mounted in the mounting groove 6, and the mounting groove 6 is covered by the end cover, which avoids outward protrusion of the driving box 32 relative to the end portion of the middle frame 1, so that the contour of the end portion of the air conditioner is flat and aesthetically pleasing, and the mounting groove 6 and the end cover both can reinforce the firmness of the mounting of the driving box 32.
  • the mounting of the driving parts may be firm, and during the operation of the air conditioner, the driving parts are not prone to shaking, and do not make noises.
  • the distance required to be driven on the outer guide rotating shaft 21 may be shortened, the transmission effect is improved, the occurrence of slip is avoided, and deformation of the outer guide rotating shaft 21 is effectively prevented.
