One word lock and cross lock which is better

The lock cylinder is graded. According to the safety level, the popular anti-theft door locks on the market are roughly classified into A, B and C. The A-level lock and the B-class lock are commonly used by the public. The lock cylinder level is incremented from the A, B and C safety factors, so the safety of the A lock cylinder is relatively lower than the rest.

Class A lock cylinder: generally includes cow head lock, traditional one-word lock, cross lock, crescent lock and most lock cylinders with only one row of marble structure locks. The anti-theft performance is poor. The opening time is usually in a few seconds to two. In a minute or so, many developers have a Class A lock. Because the bull's head lock is too backward, people generally do not use such lock cylinders. Now the locks in the citizens' homes are mostly locked by words and cross locks.

Class B lock cylinder: Generally, it contains a lock with a double-row marble structure and a lock with a combination of a single row of marbles and blades. The anti-theft is general, and the professional locksmith needs to open for 1 to 5 minutes.

Super B-class lock cylinder: generally includes multiple rows of marbles and multi-row blade combination locks, as well as full-blade and side-column structure locks. In the current three types of lock cores, the anti-theft is best, basically can not be technically opened, in cumbersome The case can only be destructively opened.

A word lock is a simple lock with an internal structure. The internal lock marbles are all arranged in a single line, so they are called a one-word lock. The lock has a simple structure and low price, but the anti-theft property is poor. There are many ways to open such a word lock. The more common ones are single hooks, hitch keys and homemade tools. The opening time of a person with mature technology is generally only a few seconds, and the longest is no more than 1 minute.

The cross lock is also a simple lock with an internal structure. The internal lock is arranged in a zigzag pattern, so it is called a cross lock. The structure of this lock is also relatively simple and has poor security. The cross lock is also a Class A lock. Its safety performance is similar to that of a normal one-word lock. It is a type that is easily opened, and the interlocking key has a very high mutual opening rate.

In the case of a word lock and a cross lock unlocking, it is still easy to open after a word lock is locked. Most of the crescent locks and cross locks that are opened are unlocked, that is, the two types of locks can further improve the anti-theft performance by anti-locking. In the market today, the types of door locks that are most easily opened are, in turn, a word lock, a cross lock, and a magnetic lock.

Through the above description, I believe that everyone knows that the safety factors of these two locks are relatively low, so you can check the lock at home. If you still use A-level locks at home, you can replace the locks with B-level and above. The lock cylinder will be safer. And put on the super B-class lock, as long as you can change the lock core, the cost is between 100 yuan and 200 yuan. When people buy locks, they must look at the number of marbles and lines of the lock, the more locks on the marbles and lines, the higher the safety performance; you can also ask the owner about the type of lock and choose what you need. Whenever possible, don't let the thief have a chance!

How to prevent technical unlocking

Due to the government's gradual liberalization of door lock supervision and the explosive spread of criminal tactics in recent years, thieves have a simple way to learn to unlock their locks, and various methods of technical unlocking have gradually increased. You can prevent technical unlocking cases through the following aspects:

1, anti-lock

Anti-locking door is often troublesome for many people, but it is the most economical and simple anti-theft method. There are 9-12 lock tongues on the upper, middle and lower sides of the security door. After the lock, all the lock tongues will stick out and lock. In order to increase the difficulty of technical unlocking, on the one hand, it can prevent the crowbar from smashing the door, on the other hand, it can increase the difficulty of technical unlocking of the offender, prolong the time of committing crimes, and increase the probability of criminal behavior being discovered. Therefore, you must remember to go out to lock the door when you go out, and lock the room indoors before going to bed at night.

2, reverse buckle

As long as the door lock is reversed, the technical unlock can not open the door lock. Therefore, in the case of someone at home or at night during the day, the door should be buckled on the basis of the anti-locking, that is, the latch below or next to the locking hole is reversed.

3, replace the high security door lock

There are some door locks on the market that are higher than Class A and Class B standards, especially the intelligent anti-theft locks. The mechanical locks and the electronic locks are divided into two parts, and the two parts are separated. The thieves can't open the door lock even if they have the same key.

4. Install alarms and other preventive facilities

The "thief" is clever, but it is also timid. If you are a little bit tempted, you may give up the target. Then, after installing an electronic alarm on the door, an alarm will sound when someone touches the door, enough to scare off the criminal. There are many types of alarms, such as infrared alarms, vibration alarms, telephone alarms, remote control, and remote control; prices range from tens of yuan to several hundred yuan, and there are several kinds of products on the Internet and in physical stores. Residents can choose to use according to their actual situation.

5. Enhance awareness of safety and prevention

In addition to physical defense, more importantly, civil air defense, residents must be vigilant, have a sense of security, remember to check the doors and windows every morning and evening, do not let the criminals have a chance.
