The mortise lock is a very popular and ancient design that has stood the test of time. They are sturdy and reliable. Their structures are also relatively diverse. Modern mortise locks are a popular lock often used in the security industry of commercial locksmiths. Its rugged design has stood the test of time. Mortise locks can be used for decades. In fact, these mortises exist in old houses and buildings and are resistant to bad weather and time.
The mortise lock has a long life, so understanding the structure and principle of the mortise lock can provide great help for installation and maintenance.
Below we understand the working principle of the mortise lock from these two aspects:
1. The mortise lock parts
The mortise lock must fit neatly into the mortise cutout or pocket on the door. There are four basic parts to a lock:
●Trim: Door lever, door knob or door handle
●Percussion board: Metal lining located in the hole in the door frame
●Cylinder: Where lock and unlock functions occur
2. How does the mortise lock work?
When the mortise lock acts on the doors' opening and closing, the door handle is used to drive the latch, which drives the follower to rotate, causing the latch to retract and the door to open. When the handle is reset, the latch spring of the mortise lock body acts, and the latch also resets. When the door is closed, the door is buckled to keep the door in a closed state and the door is closed.
When the mortise lock not only acts on the door opening and closing, but also acts as security, the core safety of the mortise lock body lies in the lock cylinder. The lock cylinder is a device that twists the dead bolt and drives the latch. After the key is inserted into the lock cylinder and turned, the cam drives the dead bolt of the lock cylinder to open or retract. When the door is closed, the latch fastens the door and turns the lock cylinder knob or key to lock the door to meet security requirements.
The mortise lock has slightly different components for each model and brand, but the mortise is designed to withstand use. The mortise lock can be fully utilized, which is very suitable for businesses and buildings with high traffic.
