Fire resisting window capable of being automatically closed
The invention provides a fire resisting window capable of being automatically closed. The fire resisting window comprises a window frame, a window, a pulley, a pull rope, a worm wheel, a worm, supporting plates, a shell, a first transverse plate, a connecting rod, a second transverse plate, a limiting stop block, a spiral spring, a cylinder, a piston and an ejector rod. The worm is rotationally connected between the two supporting plates and engaged with the worm wheel, one end of the connecting plate is fixedly connected with the middle of the first transverse plate, the middle of the secondtransverse plate is fixedly connected with the other end of the connecting rod, one end of the spiral spring is fixedly connected with the bottom face of an inner cavity of the shell, the other end ofthe spiral spring is fixedly connected with the bottom of the second transverse plate, one end of the cylinder is fixedly installed on the top face of the inner cavity of the shell, the piston and the inner wall of the cylinder are in sliding sealing connection to form a sealed cavity, the sealed cavity is filled with thermal expansion matter, one end of the ejector rod is fixedly connected withthe piston, and the other end of the ejector rod is located over the second transverse plate. The fire resisting window can be automatically closed when a fire occurs, and is simple in overall structure.
本发明提供了一种可自动关闭的防火窗，包括窗框、窗户、滑轮、拉绳、蜗轮、蜗杆、支撑板、外壳、第一横板、连杆、第二横板、限位挡块、螺旋弹簧、圆筒、活塞以及顶杆，蜗杆可转动地连接于两块支撑板之中且与蜗轮啮合，连杆的一端与第一横板的中部固定连接，第二横板的中部与连杆的另一端固定连接，螺旋弹簧的一端与外壳的内腔底面固定连接，另一端与第二横板的底部固定连接，圆筒的一端固定安装在外壳的内腔顶面上，活塞与圆筒的内壁滑动密封连接以形成一个密封腔室，密封腔室之中填充有受热膨胀物质，顶杆的一端与活塞固定连接，另一端位于第二横板的正上方。本发明可以使防火窗在火灾发生时自动关闭，其整体结构简单。
