Fireproof window capable of being automatically closed
The invention provides a fireproof window capable of being automatically closed. The fireproof window comprises a window frame, a window sash, a pulley, a pull rope, a worm wheel, a worm, first connecting plates, a transverse plate, a connecting rod, a shell, a limiting stop block, a cylindrical shape memory alloy, a baffle, an elastic film and a spine part; the worm wheel is rotatably connected onto the window frame, and the worm is rotatably connected into the two first connecting plates; a circular notch is formed in the baffle, the edge of the elastic film is in sealed connection with thenotch, the edge of the baffle is in sealed connection with the side wall of an inner cavity of the shell, the inner cavity of the shell is divided into an upper cavity and a lower cavity, the upper cavity is filled with liquid, one end of the cylindrical shape memory alloy is fixedly connected with the bottom face of the lower cavity, and the other end of the cylindrical shape memory alloy is fixedly connected with the spine part; and the spine part is located under the elastic film, and when the cylindrical shape memory alloy is heated to extend, the spine part can pierce the elastic film. Bymeans of the fireproof window, the door and window can be automatically closed when a fire occurs, fire spreading is prevented, the fireproof window is simple in overall structure and lower 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、横板、连杆、外壳、限位挡块、圆柱体形状记忆合金、挡板、弹性薄膜及尖刺部，蜗轮可转动地连接于窗框之上，蜗杆可转动地连接于两块第一连接板之中，挡板之中设有圆形缺口，弹性薄膜的边缘与缺口密封连接，挡板的边缘与外壳的内腔侧壁密封连接，将外壳的内腔分为上腔室以及下腔室，上腔室填充有液体，圆柱体形状记忆合金的一端与下腔室的底面固定连接，另一端与尖刺部固定连接，尖刺部位于弹性薄膜的正下方，当圆柱体形状记忆合金受热伸长时，尖刺部可刺破弹性薄膜。本发明可在火灾发生时自动关闭门窗，防止火势蔓延，其整体结构简单，成本较低。
