1. First of all, let me introduce class A locks. At present, most A-class locks on the market are single-character keys and cross keys. The structure of Class A lock core is relatively simple, but it is only limited to the change of marble, and the marble grooves are few and shallow. The anti-technology opening time is 1 min, and the mutual opening rate is extremely high.

2. Next, let's talk about class B locks. The key of Class B lock is a flat key with double rows of marble grooves. The difference with Class A lock is that there is a row of irregular lines on the key face. But there are mainly three kinds of lock cores, namely, computer double-row lock core, double-row crescent lock core and double-sided blade lock core. The anti-technology opening time is less than 5 minutes, and the mutual opening rate is high. The lock core can be opened in 0/minute with the powerful twisting tool/kloc.

3. finally, talk about class c locks. The key shape is a single-sided blade internal milling key or external milling key, and the lock core type is a side column lock core; However, after testing by the Ministry of Public Security for 270 minutes, it is technically impossible to open it, and its regional opening rate is zero (11 in 6 million). The marble structure is locked by double rows of blades and V-shaped side columns; If the lock core is opened with a strong twist tool, the inside of the lock core will be destroyed and locked by self-explosion, which will make it impossible to open it.

2. How to choose the anti-theft lock cylinder?

1. Let's talk about it next. When buying a lock core, everyone should look at the "teeth" of the key. But the more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.

2. Then, everyone chooses the lock and weighs it. The first is the weight, and the second is the lock core. The heavier the weight, the better the quality of the lock core, so the more beads in the lock core, the better the anti-theft function.

3. Next, let's talk about choosing the lock core to see the color, and see the workmanship than the color. But the lock core with good quality is electroplated, with smooth surface and bright color. But the dark yellow one is copper core, which is strong and has good anti-theft performance. The lock core is dull in color, and the zinc alloy with bubbles is gray in color, so the anti-theft performance is average.

Nowadays, people will install a good security door when decorating their houses, but how to choose the lock core is the level guidance of the security door lock core mentioned in the above article, and how to choose the security lock core. Bian Xiao is not clear about this.
