AI Technical Summary
The existing synchronous control devices for electric double swing doors are not effective, have poor synchronization, are complex in structure, consume a lot of electricity, are prone to accidents, and are difficult to restore synchronization.
The left and right electromagnetic clutches drive the left and right drive shafts, respectively. Combined with a synchronizing device and a geared motor, the two doors are controlled synchronously. The electromagnetic clutches provide buffer protection to prevent overload, and the doors are opened and closed synchronously using a transmission chain or synchronous belt.
It achieves good synchronization control of the two doors, saves energy, has a simple structure, is easy to adjust the synchronization state, reduces the occurrence of failures, and extends service life.
