Fireproof aluminum alloy door and window with sealing structure

Abstract

The invention provides a fireproof aluminum alloy door and window with a sealing structure and relates to the technical field of fireproof doors and windows. A mounting groove is fixedly embedded in the rear side wall of the right end of a fan blade frame, a mounting seat is movably embedded in the mounting groove, a sealing strip is fixedly arranged on the rear side wall of the mounting seat, and a supporting rod is fixedly arranged on the front side wall of the mounting seat; the front end of the supporting rod is fixedly arranged on the rear side wall of a supporting seat, connecting frames are arranged on the left side of the mounting groove, driving gears are rotationally arranged on the connecting frames on the upper side and the lower side through bearings, driven gears are rotationally arranged on the connecting frames through bearings and supporting racks are fixedly arranged at the upper and lower ends of the left side wall of the supporting seat. Driving rack sets are fixedly arranged on the rear inner side walls of the sliding grooves in the upper side and the lower side. For a side-hung door and window structure, a sealing piece is arranged to be of an adjustable and movable structure, a transmission piece is arranged, the sealing piece is arranged to be of a structure capable of stretching and retracting along with movement of the frame, the position of the sealing piece is conveniently controlled, and sealing between the frames is achieved.

Description

technical field [0001] The invention relates to the technical field of fireproof doors and windows, in particular to a fireproof aluminum alloy door and window with a sealing structure. Background technique [0002] The aluminum alloy material has the characteristics of lightness, wear resistance, and high temperature resistance, so it is often used in door and window frames when making fireproof doors and windows. However, the aluminum alloy material has poor sealing performance due to its poor plasticity. The seal will be fixed on the side wall of the frame, and then the seal between two adjacent frames will be realized. However, in the event of a fire, this sealing structure will seal the door and window parts, resulting in a pressure difference between the indoor and the outdoor. , resulting in doors and windows not being able to open normally, thereby affecting escape. To solve this problem, it is necessary to improve the seals of existing aluminum alloy doors and windo...
