The invention relates to the field of fire fighting equipment, in particular to a fireproof door which comprises a door frame and a door plate, the door plate is rotationally installed on the inner side of the door frame through two rotating shafts, the two rotating shafts are arranged in parallel and connected with the door plate through splines, and the two side ends of each rotating shaft are a first end and a second end respectively; the fireproof door further comprises a limiting structure and a switching mechanism, the limiting structure is arranged on the door frame and used for being connected with the first end in a clamped mode, the switching mechanism drives the rotating shafts to move in the axial direction of the rotating shafts and is connected with or disengaged from the limiting structure, the two rotating shafts, namely the main shaft and the standby shaft, are arranged on the door plate, and the main shaft and the standby shaft are switched in the case of a fire. The fireproof door can be normally opened and closed, the fireproof effect is ensured, and fire spreading caused by untight closing of the fireproof door is avoided.
本申请涉及消防设备领域，特别是一种防火门，包括门框、门板，所述门板通过旋转轴转动安装于所述门框内侧，所述旋转轴有两根且平行设置，两根所述旋转轴与所述门板均通过花键连接，所述旋转轴的两侧端头分别为第一端头、第二端头；该防火门还包括设置于所述门框上并用于卡接所述第一端头的限位结构、驱动所述旋转轴沿其自身轴向移动并与所述限位结构连接/脱离的切换机构，在门板上设置两根旋转轴，即一根主轴和一根备用轴，在火灾时切换主轴和备用轴，避免主轴因平时使用磨损造成门板无法开关，保证防火门能够正常开关及防火效果，避免防火门关闭不严造成火势蔓延。
