Working principle
Mechanical locking principle: When the elevator door is closed, under the action of the force element, the lock hook will tightly hook the lock stop to form a mechanical lock. According to national standards, the engagement depth of the lock hook must reach more than 7 mm, and the locking state cannot fail when a force of 1000 Newtons is applied in the door opening direction to ensure that the door will not be easily opened.
Electrical verification principle: Only when the engagement depth of the mechanically locked lock hook reaches 7 mm, the electrical safety contact will be connected, and the elevator control system will allow the elevator to start running only after receiving the door lock closing signal. If the door is not completely closed or the locking depth is insufficient, the electrical contact will be disconnected, and the elevator will stop running immediately or fail to start.

Maintenance and inspection
Maintenance points: Maintenance personnel need to regularly check the engagement depth of the door lock, the wear of the lock hook, the sensitivity of the electrical contacts, etc., to ensure that the door lock device is always in good condition. At the same time, pay attention to cleaning and lubricating the door lock components to prevent dust, oil, etc. from affecting the normal operation of the door lock.
Inspection items: including operation inspection, mechanical test, electrical test, etc. The operation inspection mainly verifies whether the mechanical and electrical components of the door lock device operate safely and correctly; the mechanical test is used to verify the strength of the mechanical locking components and electrical components, including endurance test, static test and dynamic test; the electrical test mainly checks the durability of the electrical contacts, circuit breaking capacity, leakage current resistance, electrical clearance and creepage distance, etc.
