[0037] The waist-shaped groove 8 is located inside the sealing plate 4 and is set to pass through in the front-to-back direction. The waist-shaped groove 8 is a waist-shaped through-hole structure and is set in the vertical direction. The groove teeth are located inside the waist-shaped groove 8 and are distributed toward the inner side of the waist-shaped groove 8. The transmission wheel 9 is located at the end of the rotating shaft 6 and is coaxially connected to the rotating shaft 6. The waist-shaped groove 8 is meshed with the transmission wheel 9 through the groove teeth. When the sliding window needs to be closed, the window sash 1 is pushed close to the frame 3, and the window sash 1 slides along the direction of the slide groove 2, and the rack 5 is docked with the gear 7.

Before the rack 5 is docked with the gear 7, the gear 7 is first slid and guided with the introduction part, and then meshed with the rack 5 to alleviate the impact of the direct docking between the rack 5 and the gear 7 and extend the service life. When the sliding window needs to be closed, the window sash 1 is pushed close to the frame 3, and the window sash 1 slides along the chute 2. During this period, the rack 5 and the gear 7 do not come into contact. When the window sash 1 is close to the end position of the chute 2, the rack 5 and the gear 7 start to dock again, driving the sealing plate 4 to move vertically until the window sash 1 abuts against the frame 3. The sealing plate 4 remains stationary and closes the gap between the window sash 1 and the chute 2 to prevent the sealing plate 4 from extending prematurely and clamping the window sash 1 during the sliding process of the window sash 1.
