Description

Technical Field

[0001] The utility model relates to the technical field of door and window frames, and in particular to a sealing structure for an opening and closing window. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and leafs. Opening aluminum alloy windows are formed by leaf windows and fixed frames. Leaf windows can be pushed open on the fixed frame through hinges to open or close the window.

[0003] However, the existing opening and closing aluminum alloy windows usually have only one layer of sealing, that is, after the sash window and the fixed frame are closed, a sealing layer is used to seal the sash window frame and the fixed frame around to prevent water from penetrating into the room and to prevent dust.

[0004] However, in the above-mentioned sealing structure, since the sealing strip is installed on the aluminum frame, the thermal conductivity of the aluminum frame is relatively high. Under long-term use, the sealing strip is prone to aging under long-term heat. Moreover, since there is only one layer of sealing, after the sealing strip ages, the sealing performance of the window decreases, which makes it easy for water to seep into the room.
