One end of the locking rod is hinged to the lock housing, and the locking rod sensor is mounted on the other end of the locking rod. The magnetic locking base has a slot, and the locking rod has a locking latch at the end near the locking rod sensor. The locking latch engages in the slot. The locking rod sensor detects that the locking rod is closed to the lock housing. The electromagnetic lock is connected to a floor controller via a signal line.
[0006] As a preferred technical solution, the two ends of the locking rod are respectively fixedly connected to an outer handle and an inner handle for driving the locking rod to rotate. The outer handle is located outside the landing door and is parallel to the locking rod, while the inner handle is located inside the landing door and is perpendicular to the locking rod.
[0007] As a preferred technical solution, the output end of the electromagnetic lock is provided with a locking tongue that can engage with the locking rod.
[0008] As a preferred technical solution, the electromagnetic lock is provided with a forced unlocking rod, which is connected to the lock tongue.
[0009] As a preferred technical scheme, the lock magnetic base is a U-shaped profile with an upward opening.
[0010] As a preferred technical scheme, the U-shaped groove bottom of the lock magnetic base is provided with a first buffer block.
[0011] As a preferred technical scheme, the U-shaped opening side of the lock magnetic base is provided with an outwardly inclined upward guide block.
[0012] As a preferred technical scheme, the lock shell is provided with a second buffer block on the top.
[0013] As a preferred technical scheme, the lock shell is provided with an observation hole aligned with the electromagnetic lock.
[0014] As a preferred technical scheme, the lock shell is provided with a wiring sleeve for protecting the signal line of the electromagnetic lock.
[0015] The beneficial effects of the present application are that the present application has higher safety and reliability compared with the traditional door latch structure. Only when the lock buckle is clamped into the clamping groove, the lock rod sensor on the lock rod sends a door closing signal, which can avoid safety accidents. The layer door lock rod can be opened from both sides through the inside and outside handles, which is more convenient to use. BRIEF DESCRIPTION OF DRAWINGS
