Summary: A good lock to protect the whole family, if you buy a bad lock minutes is dangerous! Therefore, when the door lock is purchased, the type of the lock cylinder is a headache. There is a blade lock on the market now. What lock is this? Is the blade lock cylinder safe? What is its principle? Let's take a look at this popular science with Xiaobian.
Is the blade lock core safe?
A good lock for the whole family, about the blade lock, is the lock core safe?
For the blade lock cylinder, this is the safest lock cylinder at present. It has higher anti-theft performance than the AB lock core because it adds an additional slot on the basis of the AB lock double-sided double-row marble, and it adopts The structure of the side column lock is that the top of the lock is on the side. The focus of the general shackles is two points above and below. In the test of the public security department, such a lock cylinder requires about 270 minutes to open the technology. This is the most basic difference between the blade lock cylinder and the AB lock cylinder. Security door lock core level
The principle of the blade lock is to use a tooth with a different angle of the bevel on the key to rotate and align the blade with different angle changes in the lock core, thereby realizing a lock in which the lock cylinder is rotated and opened.

A good lock for the whole family, about the blade lock, is the lock core safe?
The blade lock is a kind of lock product which is completely different from the traditional mechanical lock and has relatively high safety performance. The principle of the blade lock is to use the teeth with different angles of the bevel on the key to rotate and align the blades with different angle changes in the lock core. A kind of lock that the lock cylinder rotates open; but the blade lock is in the working process, and the principle of its specific work is not so simple. What is the working process and principle of the blade lock?
1. When the key is inserted into the lock cylinder, if all the key teeth on the key match the step difference of the blade, the notch on all the leaves in the lock core forms a straight groove, and the movable pin in the lock core acts under the elastic force. Will fall into the trough, the movable pin in the middle shell will also fall, the part of the trough which is taken out of the outer casing slides into the vane groove in the lock core. At this time, the key is turned, the key will drive the lock core, and the lock core drives the middle shell. Rotating together, the transmission structure of the middle casing is also rotated at the same time, the door lock can be opened and closed;
2. If one or several of the key teeth on the key do not match the step difference of the blade, the notch on the blade inside the lock core will not form a straight groove, and the movable pin in the lock core will not fall into the groove. Inside, the movable pin in the middle shell is caught by the movable pin in the lock core and cannot be removed from the tank body in the outer casing, so the middle shell is connected to the outer casing and does not rotate, and the movable pin in the middle shell does not fall. In the blade slot in the input core, the middle case is separated from the lock core. At this time, the key is rotated, only the lock core rotates, and the middle case does not rotate, so that the door lock can not be switched.
3. If other foreign objects are inserted into the lock cylinder, it is difficult to encounter the opportunity to match the level difference between the lock core and the blade. Therefore, the result can only be that the lock cylinder rotates, the middle shell does not rotate, and the door lock cannot be opened.
Please pay attention to the direction of insertion of the key when using it: the key handle must be vertical, and the raised dot on the key handle (the key is correctly inserted into the direction mark) above can be inserted into the keyhole. After confirming that the key has been fully inserted, turn the key clockwise to unlock it. Never open the key when the key is not inserted, forcibly unlocking the key, causing the key to die in the lock cylinder and unplugging or twisting the key. The key cannot be pulled out during the rotation. Only when the key is turned counterclockwise, the key can be pulled out.
