Mortise and cylinder lock is one of the most common lock structures. Its principle is to use a number of cylindrical parts of different heights (called lock springs, marbles or beads) to lock the lock cylinder. When the key is correctly placed, the lock springs are pushed to the same height and the lock cylinder is released.
The mortise lock components are generally divided into three parts: handle, lock cylinder and lock body. They are installed in the indoor door and the security door, and are also one of the most common locks on the market.
According to mortise lock manufacturers and mortise lock suppliers, there are three types of cylinder lock.
Single tongue mortise lock
This kind of lock has only one square locking tongue, which is mainly used for accessing frequent gates such as shops, theaters, hotels, etc., as well as access doors such as hotels and office buildings. According to the number of locks, it is divided into 2 types: single-head lock and double-head lock. The single-head lock only installs a marble lock on the outdoor side of the lock body. The key is opened and locked on one side of the lock head and the lock is rotated on the other side by a knob. The double-head lock is equipped with a marble lock on each of the indoor and outdoor sides of the lock body, and both sides need to be opened or locked by a key.
Single lock button mortise lock
This type of door lock has only one beveled lock tongue. This lock is equipped with a pair of handles. One side is equipped with a lock cylinder, and the inside of the room is locked by a knob on the handle. In the case of no lock, the lock can be opened by the handle inside and outside. Wind proof is the advantage of mortise lock. When locked, the handle cannot be moved. This type of lock is often used on office door or on the door of a home interior.
Double tongue mortise lock
This type of lock has two tongues, a tongue and a tongue. Nowadays, many have been installed on the security door. According to the function of the handle is divided into single way mortise lock, double way mortise lock and quick open mortise lock. Single way means that the handle is fixed on the outside, and the inside side can be pressed down to open the oblique tongue; the double way means that the handles on both sides can be pressed down to open the oblique tongue; the quick opening means that the outdoor and indoor handles can be lifted.
