The blocking plate 51 can be further limited by the stopper 53. At the same time, the chamfer on the stopper 53 allows the blocking plate 51 to move when the first sliding window 3 drives the blocking plate 51 to move, so that the blocking plate 51 can push the stopper 53 into the window frame 1 through the chamfer. Insert the end of the sliding rod 64 away from the window frame 1 into the air curtain machine body 2, then pass the connecting rod 62 through the connecting block 61 and the slide rod 64. This connects the air curtain and the slide rod 64. There are two slide rods 64, one of which is fixedly connected to the movable plate 49. The air curtain body 2 is now slidably mounted on the window frame 1 by connecting to the slide rod 64. A second spring constantly pulls the connecting rod 62 into the slide rod 64, preventing the slide rod 64 from accidentally falling out of the slide rod 64. The inner bottom wall of the rolling groove 66 is parallel to the top surface of the window frame 1.
