[Super B-class lock core] What is the difference between super B-class lock core and C-class lock core?
I. Classification of lock cores
Most of our friends still have a certain understanding of locks, but when it comes to lock cores, there is still a little confusion. Today, Xiaobian will first introduce the classification of lock cores for everyone. The classification of lock cores is generally based on their anti-theft levels. From low to high, they can be divided into three categories: A-class lock cores, B-class lock cores and super-B-class lock cores. Today, let’s mainly learn about super-B-class lock cores.
Second, what is a super class B lock core?
Speaking of super-B lock core, we should all know that its anti-theft performance is the strongest, so how strong a lock core can be called super-B lock core? After the appraisal of relevant departments, only the lock core that can’t be opened by technology or takes 270 minutes or more to open can be qualified to be called super B-class lock core. So what are the advantages of the super B-class lock core? Let’s continue to look down.
Third, the advantages of super B-class lock core are introduced
The marbles in the general anti-theft lock core can be opened in a short time as long as people with certain skills, while the marbles in the super B-class lock core are all composed of very precise number marbles and opposite-sex marbles. Even with superb technology, it is difficult to toggle both anti-theft lock cores at the same time, so it is impossible to open them. Moreover, the lock core is also equipped with a lateral internal pressure side column locking device, which is difficult to open even if violence is used.
Fourth, the price analysis of super B-class lock core
For an anti-theft lock core with such excellent anti-theft performance, I believe everyone is very excited about it, and they are certainly very curious about the price of the lock core. In fact, the price of this lock core is hard to say. Some lock cores cost several hundred yuan, while others really only need tens of yuan, because there are still many counterfeit products of this kind of lock core at present, so everyone must pay attention when purchasing. Generally, the price of a better super B-class lock core is around 200 yuan.
Let’s talk about the classification of lock cores first.
The lock core is a component used to control the lock to open, and it is the core part of the lock. Usually, people think that the lock core has three levels: A, B and C, but this is not the case. According to GA/T73-1994 "Mechanical Anti-theft Locks", anti-theft locks are divided into three grades: A, B and Super B, and C-level countries have not yet formulated standards. The C-level locks currently sold in the market are actually Super B-level blade locks, and C-level locks should be the concept defined by enterprises. However, super-class B locks and so-called class C locks must meet the basic requirements of national class B locks, that is, super-class B locks and class C locks can be regarded as class B locks.
That is to say, class C lock is just a folk name, which is actually a super class B lock, belonging to the category of class B lock, but its anti-theft performance is much stronger than that of class B lock.
Let’s talk about the characteristics of these three lock cores in detail.
Ordinary A-level lock core: generally, the security doors installed 10 years ago are all A-level lock cores, with flat keys, also known as one-word locks, and only double-sided single-row bullet slots. In terms of anti-theft performance, it only takes about two or three minutes to unlock the lock, and it is faster for the skilled.
Class B lock core: From the key point of view, it is a double-sided double-row bullet slot, which belongs to the safer class B. It takes about 5-20 minutes for a skilled worker to unlock the lock.
Super B-class lock core: This is a relatively safe level at present. From the key point of view, it is generally double-sided and double-row with internal milling grooves, and there is a blade or curve next to it. The anti-theft of this kind of lock core can reach 270 minutes, even for skilled veterans, it takes about 2 hours.
However, according to statistics, more than 50% of users are still using Class A locks. Although some Class A locks have multiple turns to improve the safety of the locks, the Class A locks can still be successfully cracked in the hands of thieves in dozens of seconds, and consumers are urged to replace the safer Class B lock core in time.
Finally, I would like to introduce you to the matters of changing the lock core.
First of all, the lock core upgrade does not need to change the whole door, just change the lock core. Consumers can remove the lock cylinder by themselves, and purchase a higher-level lock cylinder according to the specifications and models of the removed lock cylinder. The lock core can be replaced in general regular security doors.
Secondly, confirm the specifications of the lock cylinder before replacement. There are many kinds of anti-theft locks in the market, and the standards are not the same. Consumers should pay attention to the model specifications of anti-theft locks and replace them one by one. The general B-class lock cylinder and the general lock cylinder have the same shape and installation size. However, there are also special anti-theft door locks with different specifications. Please confirm the specifications of the lock core before buying.
