The locking function of the automatic door is basically realized by using several methods: electric plug lock, magnetic lock, motor self-locking, and the like.
Electric plug lock
Most of the earliest automatic doors were realized with electric plug locks, and there were two special and non-dedicated ones on the market. The special electric plug lock is an electric lock designed for the characteristics of the automatic door. It was originally imported from Taiwan. This kind of lock can be applied to the automatic doors of various brands. The working principle is to send signals to the electric locks by sensors or access control machines (such as self-service bank card machines). After the electric lock receives the signals, it first unlocks and sends signals to the automatic doors to open the door. Because the lock is first unlocked and the control unit of the lock sends a signal to the door machine controller to open the door, the door lock is avoided because the door is opened and the lock is not opened. And the lock control unit has the function of delay outputting the door open signal so it is called the special electric lock. The advantage of the special electric plug lock is that it is more difficult to open the door with destructive force, and it is more difficult to be forced to open the door. However, the wiring of such locks is more complicated. And are professional manufacturers to do automatic doors, the price is more expensive, domestic manufacturers can consider independent development, the lock body can be equipped with universal lock on the market. Ordinary electrical plug lock is the general electronic control lock, this type of lock can not delay the output of open signal, only by the access controller (sensor) at the same time open the door and unlock signal, it often happens that the door than the lock to open faster, The slinger hits the unopened lock and causes the automatic door to fail (such as the door machine self-detection, door drop, card door, etc.). We often see reports of self-service banks locking people in the house.
Magnetic lock
The magnetic lock is also the same as the electric plug lock, depending on whether it is an automatic door design or not. There is only one way to lock the door. One is locked by a lock (tongue) and the other by a magnetic force. The advantage of the magnetic lock is that the door is closed, there is no active clearance, to prevent the child from pushing the door body caused by the fault, the disadvantage is that the door can be pulled apart beyond the bearing capacity.
