The invention discloses a fireproof elevator landing door which comprises a door plate, a fireproof sealing plate, a swing arm, a first rotary connecting piece, a second rotary connecting piece, a fixed supporting component, a limiting rod and a first blocking piece. The fixed supporting component is fixedly installed on a door plate, and the swing arm is rotatably installed on the fixed supporting component through a first rotary connecting piece. The fireproof sealing plate is rotatably mounted at one end of the swing arm through the second rotary connecting piece, and the limiting rod is mounted at the other end of the swing arm; the first blocking piece is fixedly connected with the door plate or the fixed supporting structure through a hot melting adhesive and makes contact with the limiting rod, so that the fireproof sealing plate is kept at a first preset position, and the fireproof sealing plate cannot shield a gap of the door plate through the first preset position; the hot-melt adhesive has a preset failure temperature, when the hot-melt adhesive fails, the fireproof sealing plate is kept at a second preset position, and the second preset position enables the fireproof sealing plate to shield the gap of the door plate.
本发明公开了一种防火电梯层门,包括门板、防火密封板、摆臂、第一旋转连接件、第二旋转连接件、固定支撑构件、限位杆和第一阻挡件;所述固定支撑构件固定安装在门板上,所述摆臂通过第一旋转连接件可转动地安装在固定支撑构件上;所述防火密封板通过第二旋转连接件可转动地安装在摆臂一端,限位杆安装在摆臂另一端;所述第一阻挡件通过热熔粘结剂与门板或固定支撑构建固定连接,与限位杆接触,使防火密封板保持在第一预设位置,所述第一预设位置使得防火密封板不会遮蔽门板的缝隙;所述热熔粘结剂具有预设的失效温度,当热熔粘结剂失效时,使防火密封板保持在第二预设位置,所述第二预设位置使得防火密封板遮蔽门板的缝隙。
