Automatic limiting unit of electric door closer
The invention belongs to the technical field of door closers, and provides an automatic limiting unit of an electric door closer. The automatic limiting unit comprises a slide rail, a fixed support fixedly mounted at the upper end of the slide rail, a sliding block provided with a limiting block is slidably connected to the lower end of the slide rail, a lever provided with a limiting roller is hinged to the fixed support, an electromagnetic clamping mechanism is movably connected to one end of the lever, a reset spring is connected between the other end of the electromagnetic clamping mechanism and the fixed bracket, and the automatic limiting unit further comprises an electric control unit for controlling the electromagnetic clamping mechanism and a touch pressure switch electrically connected with the electric control unit. When no fire alarm exists, a fireproof door can be kept in a normally-open state through a mechanical structure, and when the fire alarm exists, the fireproof door is automatically closed. In addition, circuit communication can be detected when the door is opened, when the circuit communication is normal, the fireproof door can be automatically positioned and kept in the open state, when the circuit communication is abnormal, the fireproof door continues to be kept in the closed state, and safety and reliability are achieved.
本发明适用闭门器技术领域，提供了一种电动闭门器自动限位单元，包括滑轨，滑轨上端固定安装有固定支架，滑轨下端滑动连接有设有限位块的滑块，固定支架上铰接有设有限位滚轮的杠杆，杠杆的一端活动连接有电磁卡位机构，另一端与固定支架之间连接有复位弹簧，还包括控制电磁卡接机构的电控单元和与电控单元电连接的触压开关。没有火警时，可通过机械结构将防火门保持常开状态，有火警时防火门自动关闭。此外，还可以在开门时对电路通讯进行检测，当电路通讯正常时，防火门能自动定位保持在开门状态，当电路通讯异常时，防火门继续保持在关闭状态，安全可靠。
