The invention relates to the field of door processing, in particular to a fireproof door which comprises a center driving shaft, two side limiting sliding seats, two longitudinal limiting sliding seats, two seam filling devices and a three-layer door body. The upper and lower ends of the center driving shaft drive the two limiting sliding seats respectively by meashing, the left end and the right end of the center driving shaft are in engaged transmission with the two longitudinal limiting sliding seats correspondingly, the center driving shaft and the two seam filling devices are all rotatably arranged in the three-layer door body, the three-layer door body comprises an inner door, a middle frame, an outer door and a plurality of supporting connecting seats, the supporting connecting seats are evenly fixed to the inner wall of the middle frame, the outer door and the inner door are respectively fixed at the front end and the rear end of the supporting connecting seat, and slots are formed between the middle frame and the inner door and the outer door; and a plurality of limiting sliding grooves are formed in the inner door and the outer door. The fireproof door has the beneficial effects that through double-layer emergency operation, a gap existing in the door body can be closed, and inflow of fire and smoke is isolated, so that the life safety is effectively guaranteed.
本发明涉及门加工领域，更具体的说是一种防火门，包括中心驱动轴、两个侧限位滑座、两个纵向限位滑座、两个补缝器和三层门体，所述中心驱动轴的上下两端分别通过啮合传动两个侧限位滑座，中心驱动轴的左右两端分别啮合传动两个纵向限位滑座，中心驱动轴和两个补缝器均转动在三层门体内，所述三层门体包括内门、中框、外门和多个支撑连接座，中框的内壁均匀固定多个支撑连接座，支撑连接座的前后两端分别固定外门和内门，中框和内门与外门之间均有插缝；内门与外门内均设置有多个限位滑槽；本发明的有益效果为可以通过双层的紧急操作，封闭门体存在的缝隙，隔绝火和烟雾的流入，有效保障生命安全。
