Talking about the current lock type of the security door

 When it comes to security doors, many people will contact the anti-theft lock device. In fact, this type of lock is mainly in the form of a hybrid lock. In many cases, the anti-theft door lock we use is a hybrid lock. The reason why this kind of lock can become the mainstream lock of the security door is mainly determined by its characteristics, and its safety is higher than that of a single flat lock, a switch cabinet lock and a lock in the form of a handle. The reason for this is that the current hybrid locks are mainly composed of two or more types of locks, including iron chain locks, flat-type locks, handle locks and connecting rod locks. The mainstream one is in the form of a combination of a handle lock and a connecting rod lock, the handle is locked as a main lock, and the link lock is attached inside the security door.

        The key is matched with the lock cylinder of the handle lock, and when the security door is opened and closed, the main lock tongue can be freely extended and contracted. The lock core is connected to the internal link lock, and the other end of the link is connected with the tongue lock. Therefore, when the main lock tongue is extended and contracted, the auxiliary bolt connected with the connecting rod also expands and contracts. A variety of anti-theft effects. This is the main utility and feature of a hybrid form of lock.
