The invention discloses a fireproof door convenient to keep open and capable of being automatically closed. The fireproof door comprises a fireproof door body, a door opening keeping mechanism and an automatic door closing mechanism. The door opening keeping mechanism is detachably arranged on the fireproof door main body; the automatic door closing mechanism is fixedly mounted on the fireproof door main body; the product of the door closing acting force F2 applied to the door by the automatic door closing mechanism and the distance L2 of the straight line where the rotating shaft core of the fireproof door body is located is M2, the product of the door opening acting force F1 applied to the door by the door opening keeping mechanism and the distance L1 of the straight line where the rotating shaft core of the fireproof door body is located is M1, and when M2 is larger than M1, the fireproof door body is pushed to be automatically closed; when M2 is smaller than or equal to M1, the fireproof door body is kept in an open state; when high temperature is generated in a fire disaster, the door opening maintaining mechanism is damaged, the door opening acting force F1 disappears, and the automatic door closing mechanism pushes the fireproof door body to be automatically closed. The fireproof door can be kept normally closed, can be kept in an open state when needed, and can be automatically closed when a fire disaster occurs.
本发明公开了一种便于保持开启又能自动闭合的防火门，包括防火门主体、开门保持机构和自动闭门机构；开门保持机构可拆卸地设于防火门主体上；自动闭门机构固定安装于防火门主体上；自动闭门机构施加在门上的关门作用力F2与防火门主体转动轴芯所在直线的距离L2的乘积为M2，开门保持机构施加在门上的开门作用力F1与防火门主体转动轴芯所在直线的距离L1的乘积M1，M2大于M1时推动防火门主体自动闭合；M2小于等于M1时防火门主体保持开启状态；火灾产生高温时将开门保持机构破坏使其开门作用力F1消失，自动闭门机构推动防火门主体自动闭合。本发明防火门能够保持常闭，而在需要时能够保持开启状态，在火灾发生时能够自动关门。
