Electric door closer
The invention discloses an electric door closer. The electric door closer comprises an installation base, a motor and an execution shaft, the motor is fixedly installed on the installation base, a sliding block is arranged on the installation base in a sliding manner, the motor and the execution shaft are both in linkage fit with the sliding block, a pull rod is fixedly connected to the sliding block, the pull rod is sleeved with a spring, and the end, close to the sliding block, of the spring abuts against the installation base. The pull rod is fixedly sleeved with a gasket, the gasket abutsagainst the end, away from the sliding block, of the spring, and the motor is provided with a damping circuit and a power source detection change-over switch. The power source detection change-over switch is used for detecting whether an external power supply supplies power normally or not, switching the motor to be connected with the external power supply when the external power supply supplies power normally, and switching the motor to be connected with the damping circuit when the external power supply is powered off. By means of the arrangement, the electric door closer can automatically close a door when the external power supply is powered off, and the door closing speed of the electric door closer is controlled and adjusted through the damping circuit.
本发明公开了一种电动闭门器，包括安装座、电机、执行轴，电机固定装设在安装座上，安装座上滑动设置有滑块，所述电机和执行轴均与滑块形成联动配合，滑块上固定连接有拉杆，拉杆上套设有弹簧，所述弹簧靠近滑块的这端抵压在安装座上，所述拉杆上固定套设有垫圈，所述垫圈抵压在所述弹簧远离滑块的这端上，所述电机上设置有阻尼电路和电源检测切换开关；所述电源检测切换开关用于检测外部电源是否正常供电，并在外部电源供电正常时使电机切换至与外部电源连通，而在外部电源断电时使电机切换至与阻尼电路连通。通过上述设置，本发明提供了一种在外部电源断电时也能自动关门的电动闭门器，且该电动闭门器的关门速度由阻尼电路控制调节。
