The invention provides a building evacuation door opening device. The building evacuation door opening device comprises a door lock, a seat plate, an unlocking mechanism and a security protection mechanism. The door lock comprises a lock body arranged on a door frame and a catch box arranged on a door panel. The seat plate is fixedly arranged on the top of an evacuation passageway. The unlocking mechanism comprises a touch bar, a telescopic rod, a transmission assembly and a rope I. The telescopic rod is rotatably arranged on the seat plate. The touch bar is connected to the lower end of the telescopic rod. One end of the rope I is connected with the lock body, and the other end of the rope I is connected with the telescopic rod through the transmission assembly. When a user pushes the touch bar, the touch bar drives the telescopic rod to rotate, the telescopic rod pulls the rope I through the transmission assembly to enable a lock tongue of the lock body to be separated from the catchbox. The security protection mechanism comprises a cylinder and a rope II. One end of the rope II is connected to an output rod of the cylinder., and the other end of the rope II is connected to thetelescopic rod. Through the building evacuation door opening device provided by the invention, when a person runs to an evacuation door in case of a fire and touches the touch bar, the door panel is automatically opened, and the security performance is good.
本发明提供了一种建筑疏散门开门装置，包括门锁、座板、开锁机构和安防机构，门锁包括设置在门框上的锁体和设置在门板上的扣盒，座板固设在疏散通道的顶部，开锁机构包括撞杆、伸缩杆、传动组件和绳索一，伸缩杆转动设置在座板上，撞杆连接设置在伸缩杆的下端，绳索一的一端与锁体连接，绳索一的另一端通过传动组件与伸缩杆连接，在用户推动撞杆时，撞杆驱使伸缩杆转动，进而伸缩杆通过传动组件牵拉绳索一，使锁体的锁舌与扣盒分离，安防机构包括气缸和绳索二，绳索二的一端连接在气缸的输出杆上，绳索二的另一端连接在伸缩杆上。本发明提供的建筑疏散门开门装置，发生火灾时，人员在跑向疏散门的过程中通过触碰撞杆使门板自动打开，安全性好。
