Single point door lock


The characteristics of single-point door lock are that the handle drives the oblique tongue and the key drives the square tongue; only the oblique tongue plays a locking role in the normal state. Rotating the key can extend the square tongue and play a security role. The advantages of single-point door lock are simple structure and easy to use. The disadvantages are obvious. Because of single-point lock, the sealing performance is not good, and the deformation of the door can not be prevented.

2. Multiple-Lock Door Locker


Common multiple-lock door latches can be divided into two types according to their structure: linkage door lock and door driver.

The lock body part of the linkage door lock is similar to that of the single point door lock. It adds sliding rods at both ends of the lock body. The sliding rods are connected with the connecting rods with locking points. The door clasp plate and lock seat are installed on the matching frame to achieve the effect of multiple-point locking.

3. Door Locker with Lock Hook 

On the basis of multiple-lock point door latch, the door latch with lock hook makes one or more lock points into the form of lock hook, which greatly enhances the anti-theft performance on the basis of multiple-lock point door latch.
