The invention provides an aluminum alloy fireproof window. The window comprises a window frame, a window body, a pulley and a pull rope, one end of the window body is hinged to the upper end of the window frame, the pulley is fixedly arranged at the upper portion of the window frame, one end of the pull rope is fixedly arranged at the other end of the window body, and the fireproof window furthercomprises a worm wheel, a worm, two supporting plates and a bimetallic strip. The worm wheel is rotatably connected to the window frame, the other end of the pull rope is fixedly arranged on a rotating shaft, the worm is rotatably connected to the two supporting plates and engaged with the worm wheel, the two supporting plates are fixedly arranged on an active layer of the bimetallic strip, the bimetallic strip is fixedly arranged on the window frame, and the active layer of the bimetallic strip is located above a passive layer of the bimetallic strip; when no fire occurs, the worm is meshed with the worm wheel; and when a fire occurs, the worm is separated from the worm wheel. By arranging the worm, the worm wheel and the bimetallic strip, the fireproof window can be automatically closedwhen the fire occurs, fire spreading is avoided, and the fireproof window is simple in overall structure, low in cost and suitable for popularization.
本发明提供了一种铝合金防火窗，包括窗框、窗户、滑轮及拉绳，窗户的一端铰接于窗框的上端，滑轮固设于窗框的上部，拉绳的一端固设于窗户的另一端，防火窗还包括蜗轮、蜗杆、两块支撑板及双金属片，蜗轮可转动地连接于窗框之上，拉绳的另一端固设于转轴之上，蜗杆可转动地连接于两块支撑板之上且与蜗轮啮合，两块支撑板固设于双金属片的主动层上，双金属片固设于窗框之上且双金属片的主动层位于双金属片的被动层的上方；在未发生火灾时，蜗杆与蜗轮啮合；在发生火灾时，蜗杆与蜗轮脱离。本发明通过设置蜗杆、蜗轮以及双金属片，可以使防火窗在火灾发生时自动关闭，避免火势蔓延，其整体结构简单，成本较低，适合推广。
