Since the invention of the lock, it has always been an indispensable part of the home life. The lock protects the safety of life and property of thousands of households. It is the patron saint of family safety, so the lock is naturally unfamiliar to the people.
At present, there are many kinds of locks used in China and the quality is different. According to the domestic locks and the performance analysis, the commonly used locks in China have: 1, padlock, 2, one-word dark lock, 3, cross-security door lock, 4, AB anti-theft door lock, 5, plum lock, 6, magnetic lock, 7, U-type lock, 8, password lock, 9, car lock, 10, magnetic card lock. These ten types of locks are the most common in daily life. Below I will analyze the characteristics and safety performance of these ten lock types in more detail to increase people's understanding of locks.
First, padlock
The rural and county towns where padlocks are used are mostly used in places such as warehouses in enterprises. The padlock is easy to use, the price is cheap, and the failure rate is low, so it gets a lot of recognition, but the security performance of the padlock is very poor. Basically, it can be opened with 100% violence. It is recommended not to use it in places with high safety performance requirements.
Second, a word lock
One-word dark locks are widely used, most of them are installed on wooden doors, and their structure is simple and practical. However, the safety performance needs to be improved, the anti-violence opening performance is very low, and the technology opening a word lock is very small in the current "Gang Shangjunzi".
Third, the cross security door lock
As the name suggests, the shape of the keyhole is called the cross lock. The cross lock is widely used in China. However, with the improvement of the unlocking technology, the cross lock has been easily opened by technical means, and the safety performance of the cross lock has not reached. To the people's request, so in recent years, the market usage of the cross lock has dropped significantly, and it is estimated that it will gradually withdraw from the market.
Fourth, AB anti-theft door lock
The lock is a rising star after the cross-security door lock. At present, the national anti-theft door locks basically occupy the market. When the building is constantly towering, the installation of the lock is also high. Since the lock is designed with an A key, a B key or a C key as a set of keys, the A key is designed to provide the key to the decorator during the decoration of the house. After the decoration is completed, the owner simply uses the B key to open a circle, and the lock is immediately converted into B. In the state of the key, the A key cannot open the lock. This unique design makes the building developers very much like, and a large number of cross locks are installed on the new security door. It not only saves a lot of trouble, but also plays a very good role in the safety of the residents. The explosion-proof function of the lock can also be said to be safer.
Five, plum lock
The key of the lock looks like a plum, so it is called a plum lock. The lock is easy to open violently, and the anti-technical unlocking effect is also poor, but the cost is low, and the users are not infrequent. It is not recommended to use in places with high safety requirements.
Six, magnetic lock
The lock is relatively rare, and the principle is to achieve the tethering effect by mutually repelling the S and N grades of the magnetic marble. The quality of the magnetic lock is very good, the driving point of the rotation is small, and the violent unlocking performance is good, but the technical unlocking is to be improved.
Seven, U-shaped locks
Such locks are common and are used in vehicles such as motorcycles, electric vehicles, and bicycles. U-locks have a wide variety of lock cylinders. Generally, the lock cylinders are very good. However, it is necessary to improve the anti-violence opening. Most U-shaped locks cannot resist ordinary hydraulic shears. Many "mounts" are lost under the "clam" of the hydraulic shears. For the U-shaped lock, it is generally successful to bypass the lock cylinder and directly open the violence.
Eight, password lock password lock is divided into mechanical password lock and electronic password lock. The mechanical code lock industry is to uniformly align the grooves of each rotating disk on a line, and the bolt can enter the groove to release the bolt opening. The electronic password lock is automatically released by the solenoid valve after directly inputting the corresponding password. The security code of the mechanical code lock is better than the electronic code lock, but the use of the mechanical code lock is more troublesome. The electronic code lock is easy to use, and many users choose the electronic code lock.
Nine, car lock
Of course it is used in all kinds of cars. The car lock has the common shrapnel structure, the blade has no spring structure, the inner milling and the outer milling structure, the fragmented half-chip structure, and the chip remote control are commonly used. The anti-violence opening of the car lock is based on the cost of the car. The higher the general cost, the higher the anti-violence opening, and the configuration of the central control anti-theft system, which greatly improves its safety performance.
Ten, magnetic card lock magnetic card lock is generally used in hotels, bathing places are used, home use is less or basically not used. Many high-end hotels use magnetic card locks to provide customers with security. The magnetic card lock is equipped with a built-in magnetic stripe code inside the lock. Only the corresponding magnetic stripe code can be successfully opened. Even if you degauss the magnetic strip by other methods, it can't be opened successfully. It is impossible for you to prevent the violence from unlocking. The magnetic card lock also calculates the color in the anti-theft performance.
In general, the main locks used in China are these ten types. Other locks that are rarely used are not analyzed. ( ⊙ o ⊙ ) Simple analysis of the performance of the ten commonly used locks in China, I hope to increase everyone. The understanding of the locks will help you in choosing the locks in the future, and choose the lock that is most suitable for you.
