How does a Vertical Locking Fixture work?

The working principle of the vertical locking fixture is mainly based on two major mechanisms: mechanical locking and electrical verification. ‌When the elevator door is closed, the locking fixture locks the door panel firmly in the closed position through the mechanical locking mechanism, and the electrical contacts are connected to form an electrical circuit, sending a signal to the elevator control system that the door is closed. The elevator control system will start the elevator to run only after receiving the signal. If the locking fixture is not locked correctly or the electrical contacts are not connected, the elevator will not be able to start, thereby effectively preventing safety accidents caused by the door not being closed.

The vertical locking fixture is usually composed of a lock hook, a lock stopper, a force element, a roller, a door unlocking wheel, an electrical safety contact, and a triangular lock, and each component plays an indispensable role. Among them, the lock hook and the lock stopper are the key components to form the locking effect. They lock the door panel in the closed position by meshing. The meshing depth must meet a certain standard (such as more than 7mm) to ensure the reliability of the locking. At the same time, the lock hook and the lock stopper must also have sufficient endurance and strength to withstand external shocks and vibrations without failure. The force element is the reset device of the door lock device, which is used to automatically reset the door lock to the closed state after the door is opened.
