Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and in particular to a sealing structure for a sliding door and a sliding door including the sealing structure. Background Technology

[0002] Sliding doors feature liftable, lowerable, and sliding door panels. In conventional sliding doors, sealing strips are installed on both sides of the connection between the door panel and the frame, near the interior and exterior sides, to ensure airtightness and watertightness. However, this double-sided sealing structure uses single-layer sealing strips, which have limited wind pressure resistance. When wind pressure is high (e.g., exceeding 700 Pa), the wind pressure acting on the door panel from the outside (or from the inside) causes the door panel to shift inwards (or outwards), resulting in increased compression of one sealing strip and decreased compression of the other. This leads to unstable sealing and the risk of air and water leakage. With prolonged use, the sealing strips, repeatedly compressed due to multiple door panel shifts and prolonged single shifts, may not fully recover their shape, again leading to air and water leakage. Therefore, the existing double-sided sealing structure cannot guarantee the airtightness and watertightness of sliding doors under high wind pressure. Utility Model Content
