Anonymous users2024-01-23The lock cylinder of the anti-theft door is basically divided into two levels, namely grade A and grade B; Of course, there are also some companies that have produced super B-level lock cylinders according to market demand, and C-level lock cylinders are the same as super B-level. Among them, the anti-vandal opening time of the A-class lock cylinder is more than 15 minutes, and the anti-technical opening time is more than 1 minute. The anti-vandal opening time of the B-class lock cylinder is more than 30 minutes, and the anti-technical opening time is more than 5 minutes.
In general, the anti-technical opening time of the super B-level anti-theft door lock cylinder is greater than 4 hours.
1. A-class lock cylinder.
The anti-theft coefficient is the lowest, and it really opens in minutes for thieves!
Class A locks refer to locks that use Class A lock cylinders, generally including traditional slotted locks, cross locks, crescent locks, and most lock cylinders with only a row of marble structures, which have poor anti-theft and open time in a few seconds to two minutes.
Many developers deliver the lock cylinder when they are Class A locks.
In fact, the basic function of the A-class lock cylinder is some simple privacy protection, telling the person who wants to unlock the lock "here is a locked space that does not want to be entered", so it is more of a psychological refusal, and it is not recommended to use it as an anti-theft door lock.
2. B-level lock cylinder.
Class B locks are much better, they are single-row and curved, and the difference with Class A locks is that there is an extra row of curved and irregular lines on the key surface. It can basically meet the anti-theft performance that the anti-theft door should have.
3. Super B-level lock cylinder.
The super B-level lock cylinder is actually similar to the C-level lock cylinder, using a number of anti-theft technologies, a variety of special-shaped anti-pull-out bullets, eliminating technical opening, with a unique design of the bullet and blade structure, with a high safety performance against technical opening. The lock tank is equipped with a precision number bullet and a special-shaped bullet structure, which will be automatically locked when the number bullet and the special-shaped bullet must be pulled at the same time when the technology is opened, so that the technology will be turned on in vain. Super B-level lock cylinder is currently quite high-performance lock cylinder, with a good lock cylinder, safety can be assured.
The mission of the lock is still safety first, function second. I wish you all find a good lock to protect what you want to cherish.
