[0002] With the rapid development of my country's economy, various buildings have sprung up, and the forms of doors and windows have become diverse.

[0003] For example, Chinese patent CN219587461U discloses a strip-through heat-insulating sliding door, which includes a frame and two door leaves. The frame is provided with a protrusion near the door leaves, and the door leaves are provided with two protrusions on the side near the frame. A plug-in part is provided on the side close to each other in the middle of the two protrusions, and a heat-insulating strip is inserted between the two plug-in parts, and an embedded part is provided on the heat-insulating strip. When the door leaves are closed, the embedded part of the heat-insulating strip on the door leaves is embedded in the concave part of the protrusion, so that the junction between the door frame and the door leaves has a good heat-insulating effect.

[0004] However, the heat insulation of the above-mentioned strip-through heat-insulating sliding door only relies on the heat-insulating strip at the junction of the door frame and the door leaf, and the heat insulation method is single, which easily leads to poor heat insulation effect.
