The invention discloses a fireproof door capable of exhausting smoke and facilitating escape in the technical field of fireproof doors. The fireproof door comprises a smoke exhaust mounting wall, a safety door frame and a fireproof door leaf, a smoke exhaust through hole is formed in the middle of the smoke exhaust mounting wall, smoke exhaust mounting cavities are formed in the two sides of the safety door frame, an electric control cavity is fixedly formed in the top of the safety door frame, smoke exhaust fans are fixedly mounted in the smoke exhaust mounting cavities, a folding sealing door is arranged between the smoke exhaust mounting cavities and the electric control cavity, closed sliding blocks are slidably connected in the smoke exhaust mounting cavities and the electric control cavity and rotationally connected with one end of the folding sealing door, an emergency lead screw and a set of closed lead screws are rotationally connected in the electric control cavity, the closed lead screws penetrate through the closed sliding blocks in the electric control cavity to be in threaded fit with the closed sliding blocks, the emergency lead screw is in external thread fit with a set of outer side door closing push blocks, and a fire alarm sensor is fixedly installed on the outer wall of the electric control cavity. According to the fireproof door, automatic induction and closing of a door are achieved, the fire behavior is prevented from spreading rapidly, fire diffusion is blocked to a certain degree, smoke exhaust is accelerated, the amount of harmful smoke inside is rapidly reduced, and escape time can be prolonged.
本发明公开了防火门技术领域的一种可排烟便于逃生的防火门，包括排烟安装壁、安全门框和防火门扇，排烟安装壁中间开设有有排烟通孔，安全门框两侧设有排烟安装腔，顶部固定设有电控腔，排烟安装腔内固定安装有排烟风扇，排烟安装腔和电控腔之间设有折叠封合门，排烟安装腔和电控腔内均滑动连接有闭合滑块，闭合滑块与折叠封合门一端转动连接，电控腔内转动连接有紧急丝杠和一组闭合丝杠，闭合丝杆穿过电控腔内的闭合滑块与之螺纹配合，紧急丝杠外螺纹配合有一组外侧关门推块，电控腔外壁固定安装有火灾报警传感器，本发明自动感应并闭合关门，避免火势迅速蔓延，一定程度阻挡火灾扩散，加速排烟，快速降低内部有害烟雾量，有利于延长逃生时间。
