A sealing strip Q162 is clamped on the inner side of the aluminum alloy edging B161 close to the outer frame 1, and the sealing strip Q162 is in contact with the surface of the outer frame 1. Through the seventh sealing member 16, not only can the sealing lap between the outer frame 1 and the sliding door leaf 2 be realized, improving the heat insulation and heat preservation effect at the lap sealing part, but also the aesthetics of the connection between the outer frame 1 and the sliding door leaf 2 can be improved, thereby further enhancing the overall airtightness and aesthetics of the foldable and opening PVC sliding door.
[0042] In summary, for the foldable and opening PVC sliding door, by adopting an assembly method combining welding and screwing, it is convenient for the production, transportation, and installation of large-sized doors. The threshold 4 has smooth passability and high strength for trampling, realizes the comprehensive use of multiple materials, gives full play to the physical properties of different materials, optimizes the product performance structure, is suitable for large opening requirements, meets the maximum opening amount, and is an ideal product for partitioning large openings and large spaces.
