Fire window capable of being automatically closed
The invention provides a fire window capable of being automatically closed. The fire window comprises a window frame, a window sash, a pulley, a pull rope, a worm gear, a worm, first connecting platesand a bimetallic strip, wherein 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 sash, and the pullrope crosses over a groove of the pulley; the bimetallic strip is a snap action type bimetallic disc, and the two first connecting plates are arranged; the worm gear is rotatably connected to the window frame through a rotating shaft, the other end of the pull rope is fixedly arranged on the rotating shaft, and the worm is rotatably connected between the two first connecting plates and meshed with the worm gear; and the two first connecting plates are fixedly arranged on a driving layer of the snap action type bimetallic disc, the two ends of the snap action type bimetallic disc are fixedly arranged on the window frame, and the driving layer of the snap action type bimetallic disc is located above a driven layer of the snap action type bimetallic disc. According to the fire window capableof being automatically closed, by arranging the worm, the worm gear and the bimetallic strip, the fire window can be automatically closed when a fire disaster occurs, so that fire spreading is avoided, and the fire window is simple in overall structure and low in cost.
本发明提供了一种可自动关闭的防火窗，包括窗框、窗扇、滑轮、拉绳、蜗轮、蜗杆、第一连接板以及双金属片，滑轮固设于窗框的上部，拉绳的一端固设于窗扇的另一端且拉绳跨过滑轮的凹槽，双金属片为突跳式双金属碟片，第一连接板设有两块，蜗轮通过转轴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第一连接板之中且与蜗轮啮合，两块第一连接板固设于突跳式双金属碟片的主动层上，突跳式双金属碟片的两端固设于窗框之上且突跳式双金属碟片的主动层位于突跳式双金属碟片的被动层的上方。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。
