What is a blade lock and what is a blade lock? How do you open a blade lock?

The blade lock is currently a lock that is more difficult to open, but basically the tool is not selected, and I need to use my tool to open the blade lock. It's much less difficult to open.

A blade lock is a cylindrical lock that uses a reed as a shoji, which is a neatly arranged, dense blade.

Opening of the blade lock:

When the key is inserted into the lock cylinder, if all the key teeth on the key coincide with the grade difference of the blade, then the notch on all the leaves in the lock cylinder forms a straight groove, the movable pin in the lock cylinder will fall into the groove under the action of elastic force, and the movable pin in the middle shell will also fall, and the groove part that comes out of the shell slides into the blade groove in the lock cylinder, and then the key is rotated, and the key will drive the lock cylinder.

The lock cylinder drives the middle shell to rotate together, and the transmission structure connected to the middle shell also rotates at the same time, so that the door lock can be opened and closed.

The blade lock is currently a relatively secure C-level lock cylinder, which is more difficult to open, and can be opened with this tool in the figure below.

The blade lock is a relatively safe cylinder that can be opened with the tools I have here. Remember to look, my name.

We all know that by installing doors and door locks, it can help us protect our property and personal safety at home, especially when buying a new house and living in the community, the door lock at home is very important, and only the door lock is equipped with high security, which is more helpful to prevent theft. There are many kinds of door locks, there are AB locks and blade locks, many families are installed these two locks, I don't know if you have a detailed understanding of the blade lock, the following is an introduction to the blade lock for the majority of friends.

There is a difference between AB lock cylinder and blade lock cylinder, like aluminum, iron or even plastic AB lock with a single row of upper and lower bead structure, which is not only not precise, but also has a particularly high mutual opening rate, which cannot play an anti-theft role at all.

For the blade lock cylinder, this is the lock cylinder with the highest security at present, and the reason why it has higher anti-theft performance than the AB lock cylinder is because it adds an extra milling groove on the basis of the AB lock double-sided double-row marble, and it adopts the structure of the side post card lock, that is, the lock is made on the side. The focus of ordinary people picking locks is up and down, and such a lock cylinder takes about 270 minutes to open in the test of the public security department. This is the most basic difference between a blade lock cylinder and an AB lock cylinder.

Not all blade locks can be anti-theft, some imitation blade locks are very thin, the diameter of the beads is less than 2mm, such locks can be opened with tin foil and some professional tools.

Because the blade lock cylinder is made of blade anti-theft technology, the anti-theft performance is high, and it takes about 280 yuan to replace the blade lock cylinder for anti-theft doors of brands such as "Meixin" and "Wanjia". Sometimes, when carrying out preferential activities, about 250 yuan is enough. And the "Wang Li" anti-theft door, if you want to replace the blade lock cylinder, it is slightly more expensive, between 300 yuan and 350 yuan.

The lock cylinder of the blade lock adopts a springless blade structure, and the blade lock is easy to rotate freely within the rotation range of 90 degrees if the blade lock is subjected to strong vibration and impact, resulting in the key being unable to insert, so a plastic rod similar to the key is inserted in the blade lock lock hole when the safe and cabinet leave the factory to prevent the free rotation of the blade.

Through the comparison with AB locks, we should know the advantages of leaf locks, indeed, the anti-theft performance of leaf locks is very good, there are many families are using leaf locks, the user's response is very good, usually we are on TV or through friends around us, neighbors, may have heard that the door of the house was pried open, the property in the house was stolen, which also caused everyone's warning, the door lock at home is very important, we don't use those general locks, buy a *** door lock, even if there is no one at home, our Bi Xiao will also be very down-to-earth in his heart.

The blades are divided into:Class A locks, Class B locks, and super Class B (Class C) locks. There are obvious differences in terms of technical opening time, key shape, the main differences are as follows:

Class A lock: the key is flat or crescent type, with a row of concave key slots on one or both sides, or a convex key slot on four sides of the cross type.

Class B lock: The key is flat or crescent type, with two rows of concave key slots on one or both sides, or cylindrical multi-point concave key openings.

Super B level (C level): the technology can not be opened by the public security department, or the technology is opened for more than 270 minutes, the key is flat type, single-sided or double-sided, with two rows of concave plus S-type key slots or internal and external double serpentine key slots.
