Description

A high thermal insulation lifting sliding door Technical Field

[0001] The utility model relates to a high-heat-insulation lifting and sliding door, belonging to the technical field of building doors and windows. Background Art

[0002] The lifting and sliding door is a sliding door with high sealing and high load-bearing performance, but due to its own structural characteristics, it is difficult for aluminum alloy lifting and sliding doors to achieve high thermal insulation performance.

[0003] To improve thermal insulation, existing lift-and-slide doors typically use insulating plastic profiles in the U-groove of the frame to prevent heat transfer between the two sashes at the edge. However, because plastic profiles are made of different materials than the aluminum alloy outer frame, they tend to shrink in cold weather, creating gaps in the frame. In hot weather, the plastic profiles tend to buckle, affecting the door's opening and closing performance. Existing lift-and-slide door frame and sash gaps are typically sealed with a single rubber strip. Due to the lifting motion of lift-and-slide doors, they place high demands on thermal insulation. Even with these seals, they cannot meet these requirements.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it.
