Fireproof door with emergency open structure
The invention relates to the technical field of fireproof doors, in particular to a fireproof door with an emergency open structure, which comprises a fireproof door body, the emergency open structure is arranged on the fireproof door body, the emergency open structure comprises a pull plate, a clamping device, a connector and a damper, and through the action of a door handle, the pull plate, the clamping device, the connector and the damper, the emergency open structure can be opened. The clamping block can be clamped into the clamping ring after the fireproof door is completely opened, so that the fireproof door is automatically and temporarily fixed, the fireproof door is prevented from being closed by the door closer, convenience is brought to escape personnel behind, however, under the action of the damper, the clamping block can be automatically separated from the clamping ring after a period of time of the fireproof door, and the fireproof door is prevented from being closed by the door closer. Therefore, the fireproof door is automatically closed by the door closer, the original fireproof and smoke-proof effects of the fireproof door are recovered, on the whole, the structure is simple, no complex part exists, the production cost is lower compared with other fireproof doors with the function, and the overall operation is very simple.
本发明涉及防火门技术领域，具体为一种设有应急敞开结构的防火门，包括防火门本体，防火门本体上设置有应急敞开结构，应急敞开结构包括拉板、卡接器、连接器和阻尼器，通过门把手、拉板、卡接器、连接器和阻尼器的作用，使该防火门在完全敞开后，卡块能够卡入卡环内，从而自动暂时固定住该防火门，防止该防火门被闭门器关闭，给后面的逃生人员带来方便，但在阻尼器的作用下，使该防火门在间隔一段时间后，会自动使卡块脱离卡环，从而使防火门自动被闭门器关闭，进而使防火门恢复原有的防火、防烟效果，整体上，结构简单，没有复杂部件，生产成本相对其他拥有该功能的防火门更加的低廉，并且整体的操作很简单。
