Description

Technical Field

[0001] This utility model relates to the field of doors and windows, specifically a heat-insulating structure for an inward-opening side sliding door. Background Technology

[0002] Figure 1 This diagram illustrates a common inward-opening sliding door structure. Existing inward-opening sliding doors typically include a door frame, a fixed panel, and an operable panel. The fixed panel includes a fixed panel frame and fixed glass, while the operable panel includes an operable panel frame and operable glass. The fixed panel frame comprises four sections: top, bottom, left, and right. The left section, used to connect with the operable panel, is a door hook. The operable panel frame also includes four sections: top, bottom, left, and right. The right section, used to connect with the fixed panel, is a frame stile. When the inward-opening sliding door is fully closed, the door hook and the frame stile abut against each other. The structure of these two sections has the greatest impact on the heat insulation performance of the inward-opening sliding door. Although... Figure 1 The door leaf hooks and frame mullions are equipped with heat insulation strips, but indoor and outdoor heat will be directly transferred through the aluminum profiles, so the heat insulation effect is not good enough.
