High-flame-retardance steel fireproof door
The invention discloses a high-flame-retardance steel fireproof door, and relates to the technical field of fireproof doors. The high-flame-retardance steel fireproof door comprises a fireproof door body; a rectangular through opening is formed in one surface of the fireproof door body; a containing cavity is formed in the fireproof door body; a lug plate is fixed on the inner wall of the fireproof door body; a limiting groove is formed in one surface of the fireproof door body; one end of the lug plate is rotatably connected with a gear; a fireproof partition plate is in transmission connection with the interior of the fireproof door body through a gear; rectangular grooves are formed in the front side and the rear side of the fireproof partition plate side by side; racks matched with thegears are fixed to the inner bottom faces of the rectangular grooves at equal intervals; a sealing plate is fixed to the upper surface of the fireproof partition plate; a limiting structure matched with the fireproof door body penetrates through one surface of the fireproof partition plate; and the limiting structure comprises a sliding rod penetrating through the fireproof partition plate. By using the limiting structure, the fireproof partition plate and the gears, the problems that an existing fireproof door is of an integrated structure, escape is inconvenient when a fire occurs, and theescape probability is reduced are solved.
本发明公开了一种高阻燃钢质防火门，涉及防火门技术领域。本发明包括防火门本体，防火门本体一表面开设有矩形通口，防火门本体内部开设有容纳空腔，防火门本体内壁固定有耳板，防火门本体一表面开设有限位槽；耳板一端转动连接有齿轮，防火门本体内部通过齿轮传动连接有防火隔板，防火隔板前后两侧均并排开设有矩形凹槽，矩形凹槽内底面等距固定有与齿轮相配合的齿条，防火隔板上表面固定有封板；防火隔板一表面贯穿有与防火门本体相配合的限位结构，限位结构包括贯穿防火隔板的滑动杆。本发明通过限位结构、防火隔板和齿轮的使用，解决了现有防火门为一体式结构，火灾发生时不便逃生，降低了逃生概率的问题。
