Normally-open fireproof door self-locking door closer with control device
The invention discloses a normally-open fireproof door self-locking door closer with a control device, and relates to the technical field of door closers. The control device comprises two smoke sensors, two mounting brackets and a releaser, wherein the two smoke sensors and the mounting brackets are correspondingly arranged on the wall bodies on the two sides of fireproof doors, the releaser is arranged on the mounting brackets, and the releaser is connected with the mounting brackets in a fastened mode. The self-locking door closer uses the control device and further comprises a sealing assembly, a door closer assembly and a self-locking assembly, wherein the sealing assembly is correspondingly connected with the end surfaces of the sides, far away from door hinges, of the two fireproof doors in a fastened mode, one end of the door closer assembly is connected with the fireproof doors in a fastened mode, and the other end of the door closer assembly is connected with the side wall bodies of the fireproof doors in a fastened mode. According to the sealing assembly, the position of a sealing plate is adjusted in a self-adaptive mode through the change of the positions of two first magnetic blocks in the closing process of the fireproof doors, the friction loss in the door closing process is reduced, and meanwhile, the sealing performance of the fireproof doors is also guaranteed.
本发明公开了带有控制装置的常开式防火门自锁闭门器，涉及闭门器技术领域，其中的控制装置包括烟雾传感器、安装支架、释放器，烟雾传感器、安装支架有两个，两个烟雾传感器、安装支架分别安装在防火门两侧墙体上，安装支架上设置有释放器，释放器和安装支架紧固连接。自锁闭门器使用了前述的控制装置并且还包括密封组件、闭门器组件、自锁组件，密封组件分别和两扇防火门远离门合页一侧的端面紧固连接，闭门器组件一端和防火门紧固连接，另一端和防火门侧边墙体紧固连接。本发明的密封组件，通过防火门闭合过程中两块第一磁块位置的变化，对密封板的位置进行自适应调节，并降低了在关门的过程中摩擦的损耗，同时也保证了防火门的密封性能。
