How to identify the change of the anti-theft lock core? Lock core purchase five points

The anti-theft lock core is already very safe and burglar for the masses. In fact, in the opinion of many experts, the anti-theft level of the lock cylinder in the market is too exaggerated, so that consumers have nowhere to go. From A-class B to super-B, C-class, super-C, how do you identify these lock cylinders? How to choose during the purchase process?

Here are some simple points to note about the lock core purchase:

First, good locks need good materials

The quality of the lock cylinder is closely related to the quality of the material. The material of the lock nail is very important, requires a certain hardness and toughness, and is resistant to wear and tear. The locking nail is preferably made of stainless steel or nickel alloy, such as copper wire, iron wire, aluminum, and plastic texture. The hardness of the anti-drilling bolt and the anti-drilling piece is high, and the material of the key is also more stressful, at least wear-resistant and break-resistant. In addition, the advanced lock cylinders are made of nickel (16%) and manganese (2%) alloys. The precision of the lock cylinder made of copper, iron and aluminum alloy materials has insufficient precision.

In fact, from the key can be how much to figure out the quality of this lock cylinder. The more precise the key, the more precise the hole position and the groove position, the smoother the depth, the more clearly the shallower and clearer the lock core, the better the quality. On the contrary, the key is rough, the groove is not clear, the hole depth is not obvious, and the color of the hole and the key of the key surface are different, and the quality must be poor. To put it simply, a good lock cylinder is more eye-catching and more elegant than a poor lock cylinder even when viewed from the outside.

Second, the mixed structure of rationality

The rationality of the structure of the lock cylinder is critical to the quality of the anti-theft. It is generally believed in the industry that a single structure has poorer performance than a hybrid structure. This is because each structure has its advantages and disadvantages: the anti-twist ability of the pin lock is better, but the anti-dial ability is worse; the anti-pick ability of the sheet lock is higher, and the anti-twist and anti-vibration ability is poor. . A single structure is prone to large-area structural security problems. A certain security is prone to large security problems after being cracked. We often encounter the door of a number of households being opened collectively, usually with a single structure. The lock of two or three hybrid structures has a much higher comprehensive anti-theft capability. When consumers choose a lock cylinder, they must choose a hybrid structure. If possible, try to understand his structure with the structural video provided by the manufacturer. If the manufacturer is unable to provide a structured video or is vague, it is necessary to leave more than one heart. A good lock core will definitely explain its structure in detail by video.

Third, the higher the precision, the more the quality

The precision of the lock cylinder is given by the design lock, and the higher precision often means the more reliable quality. For the manufacturer, the fully digitally designed lock cylinder is much more sophisticated than the randomly installed lock cylinder. The larger the contact surface between the lock pin and the lock pin, the smaller the punch gap, and the smaller the gap between the lock plug and the lock case, the more reliable the lock core. One way to distinguish is: the lock core of the lock nail with a knives, the lead powder to be used, the need to add any lubricant, the key cylinder with a rough key, the precision is definitely a problem.

Fourth, the anti-break opening device is like a cold coat

I often hear that most of the locks nowadays "anti-gentlemen are not against villains", and it is true after seeing many inferior locks on the market. The anti-break device is like a cold coat in the winter, and a good lock must be available. Destruction prevention mainly comes from several aspects: anti-twist setting, anti-knock setting, anti-drilling measures. That is to say, the deeper the depth of the gap between the lock pin and the plug of the lock core, the higher the density, the higher the anti-twist ability. The better the reinforcement of the lock core, the stronger the anti-knocking ability of the lock core. The drill bolt, the anti-drilling piece and the special-shaped locking nail are all for preventing the drilling core of the drill bit from breaking the structure and unlocking the structure. Therefore, if you encounter a lock cylinder that is not anti-twist, anti-knock, and anti-drill-proof drill-proof piece, please think twice.

Five, key anti-copy, safer and more careful

The advancement of the lock industry has also made the complexity of the keys simple. The phone takes a picture of the key, and it may be copied by someone with ulterior motives. Therefore, the process of the lock cylinder before delivery is also very important. At present, some manufacturers use cans packaging, which is one of the better ways to solve this problem. This eliminates unnecessary troubles through the locksmith, installer, salesman, and the like.

In summary, it is not difficult to buy a lock core with a good anti-theft performance. Just pay attention to the five aspects of material, structure, processing accuracy, anti-destruction settings, anti-copy protection, you can improve the possibility of choosing a good lock. Choosing a good brand with good reputation and excellent quality is also an important shortcut. Such as the CEI lock cylinder from Shenzhen Changen Company, its excellent and safe quality is worth recommending. Is the wool out of the sheep? The quality of the lock core comes from the design effort and cost. Consumers must choose the favorite locks objectively and reasonably with the attitude of “one penny and one share”. This is the advice given by a professional old locksmith.
