Power-off automatic reset electric door closer
The invention discloses a power-off automatic reset electric door closer which comprises a shell, a motor, a rotating shaft, a driving mechanism and an automatic reset mechanism, the motor, the driving mechanism and the automatic reset mechanism are all arranged in the shell, one end of the rotating shaft is arranged in the shell, the other end of the rotating shaft penetrates through the upper end face of the shell and then extends out, and the driving mechanism is connected with an output shaft of the motor. The driving mechanism is matched with the rotating shaft, a cam is arranged on the rotating shaft, and the automatic reset mechanism corresponds to the cam. By arranging the motor and the driving mechanism, the rotating shaft can be driven to rotate automatically, and therefore automatic opening and closing of the door leaf connected with the rotating shaft are achieved; the automatic resetting mechanism is arranged, so that when the door leaf is powered off in the opening or closing process, the automatic resetting mechanism can act on the cam to drive the cam to rotate so as to drive the rotating shaft to rotate until the door leaf is in an opening or closing state, namely, resetting of the door leaf is achieved, and the door leaf cannot stay in the opening or closing process; and automatic resetting of the door is realized.
本发明公开了一种断电自动复位电动闭门器，包括壳体、电机、转轴、驱动机构和自动复位机构，电机、驱动机构和自动复位机构均设于壳体内，转轴的一端设于壳体内，另一端穿过壳体的上端面后伸出，驱动机构与电机的输出轴连接，驱动机构与转轴相配合，转轴上设有凸轮，自动复位机构与凸轮相对应。通过设有电机和驱动机构，可以带动转轴自动转动，从而实现了与转轴连接的门扇的自动开启和关闭；通过设有自动复位机构，因此，当门扇在开启或关闭过程中出现断电时，通过自动复位机构，能够作用在凸轮上，带动凸轮转动，从而带动转轴转动，直至门扇处于打开或者关闭状态，即实现门扇的复位，不会使得门扇停留的在开启或关闭过程中，实现门的自动复位。
