AB anti-theft composite lock core features

AB anti-theft composite lock cylinder
Features
The computer slot plus the inner milling slot super AB anti-theft composite lock core is a new type of anti-theft lock core designed by the locksmith who has many years of experience in unlocking, specially designed for technical opening; the key opening; destructive opening; acid-alkaline opening. The structure of the lock cylinder has a strong anti-theft function.

Main features are introduced:
1. The ultimate anti-smashing function: the ordinary lock cylinder slot space is too large, the violent unlocking tool can be easily inserted into the key slot, and the raw materials used in the violent unlocking tool are alloy materials with good toughness and strength. Alloy materials are imaginable compared to copper marbles. The groove type of the lock cylinder is divided into four main ribs by a unique design. The key is divided into four ribs and the key is combined into one at the key opening, which plays the role of four or two. Violent tools can only work by being integrated, and such a design just hits the key to the violent twist.
2. Anti-drip prevention function: According to my experience of unlocking for more than ten years, technical unlocking generally relies on one hand to drive the lock cylinder and one hand to move the marble. (There is enough space and strength to move the hook at the same time. The tool's active space is greater than 0.8mm. The ball in the lock cylinder is misaligned to achieve the rotary lock cylinder. Because the composite cylinder has a composite structure, the shaped marble is operated by the X axis, and the I-shaped marble is operated by the Z-axis, and the gap between the two is only 0.37 mm, and the anti-picking is added between the two. With regard to the insertion and movement of the effective control technology unlocking tool, since the space is too small, it is difficult to move the marble even if a small wire is inserted, and it is difficult to control the position even if the ball is moved.
3. Anti-collision key Shock-proof opening function: Due to the chaos of the unlocking industry, some locksmiths have leaked some unskilled unlocking methods to some lawless elements in the society in order to seek small profits. With a key made by a common key (a versatile key), you can open a marble lock in a short period of time. In order to deal with the weakness of these locks, the lock deliberately adds a laterally shaped bar of the I-shaped marble. The key is opened by the impact vibration, and the I-shaped marble of the lock will be demarcated when it is hit, and the opposite-sex bar is unspring. There is no dividing line. The working principle of the opposite sex bar is like the Kongming lock. The seven notches are aligned at the same time, and the rotation will be opened. This effectively overcomes the shock-proof opening of the key.
4. No Spring and no hand feeling: This lock has seven springless shaped bars, which are positioned by the inner milling groove of the key. When the technology is unlocked, even if the horizontal bar is moved in the slot space of the lock, since there is no spring, the spring will not automatically return to the position, the force is difficult to grasp, and it is not felt when dialing, even if it is dialed. It is found that the dial has not been automatically returned.
5. Fifteen eight-level differential marbles: This lock cylinder is composed of two different kinds of marbles. The above is composed of 7 four-level differential bars. The following is composed of 8 four-stage differential cylindrical marbles. The mutual opening rate is 1/4^7*4^8.
6. Acid-proof alkaline side column: In my more than ten years of unlocking career, I have encountered many times when the thieves used sulfuric acid caustic soda to corrode the spring. Under the lock cylinder, there are cylindrical marbles with shaped bars and side columns. Since sulfuric acid and caustic soda are liquids, they will flow to a low place. That is, the use of corrosion can only damage the marbles and springs under the lock cylinder, and the side columns and the bars are not corroded by liquid on the lock core.
7. Eight I-shaped marbles: ordinary lock cylinders are generally cylindrical marbles, which have poor anti-diality and good technical unlocking. The lock cylinder adopts eight I-shaped marbles. When the technology is opened, the boundary between the lock core and the lock case is broken, and the hand feeling is difficult to control.
8. Seven shaped bars: ordinary isotropic bars in the lock core to leave the large space for the tool to insert, relatively good dial. The seven shaped bars of this lock core accounted for 75.6% of the active space, and the remaining space was small, and the difficulty of opening the technology was much improved.
9. Strict and high-precision tolerance: 90% of the existing cylinder lock tolerances in the existing market are almost 0.15mm and the maximum clearance is 0.3mm. The minimum clearance of the lock cylinder is 0.08 mm, and the maximum clearance is not more than 0.15 mm.
