The invention discloses a staircase fireproof door opening and closing structure, and relates to the technical field of fireproof doors, and particularly relates to a staircase fireproof door openingand closing structure. The staircase fireproof door opening and closing structure comprises a door frame, wherein a door body is hinged to the interior of the door frame, a step is arranged at the bottom of the door frame, a fireproof plate is hinged to the bottom of the door body, a hinge is arranged between the door body and the fireproof plate, a fixing seat is fixedly connected to the top of the fireproof plate, the top of the fixing seat is fixedly connected with steel cables, the number of the steel cables is two, the two steel cables are symmetrically distributed on the two sides of thefixing seat, a through hole is formed in the front surface of the door body, and the steel cables enter the interior of the door body through the through hole. According to the staircase fireproof door opening and closing structure, the steel cables are arranged, due to the fact that the steel cables are connected to the end, far away from the fireproof plate, of the hinge, in the process of pulling the hinge upwards by utilizing the steel cables, the force arm of the steel cables acting on the hinge is larger, so that the force consumed by the steel cables driving the hinge to rotate is muchsmaller than the force consumed by the steel cables driving the hinge to rotate relative to the force consumed by the steel cables driving the hinge to rotate close to the fireproof plate, and more labor is saved during use.
本发明公开了一种楼梯间防火门启闭结构，涉及防火门技术领域，具体为一种楼梯间防火门启闭结构，包括门框，所述门框的内部铰接有门体，所述门框的底部设置有台阶，所述门体的底部铰接有防火板，所述门体和防火板之间设置有铰链，所述防火板的顶部固定连接有固定座，所述固定座的顶部固定连接与钢索，所述钢索的数量有两个且对称分布在固定座的两侧，所述门体的正面开设有通孔，所述钢索通过通孔进入到门体的内部。通过设置钢索，由于钢索连接在铰链远离防火板的一端，在利用钢索向上拉动铰链的过程中，钢索作用在铰链上的力臂更大，所以钢索带动铰链转动所消耗的力相对于靠近防火板的一端要小得多，使用起来更加的省力。
