Consumers choose smart lock anti-theft lock core to "six look"

When we are accustomed to the rapid changes in the market, intelligent locks are coming from the sky, and all kinds of smart locks make us pick the eye. Regardless of how intelligent the product is, the smart lock is still out of the function of anti-theft. Even the smart lock must have a high-precision composite structure of the anti-theft lock core. What kind of conditions should the good anti-theft lock core have? ? Below, we let the smart lock experts teach you how to identify the material of a good lock core.

Dr. Chen, an expert in intelligent anti-theft locks, has been working on anti-theft door locks for more than 40 years. For more than 40 years, he has specialized in anti-theft door lock cylinders. The world's top ten lock core brands are the object of his research. They are also often processed for some of the top lock core brands. They know the problems and development direction of the security lock cylinder industry. They are the old experts in the domestic lock core industry. In view of the current status quo of the industry, Mr. Chen said with great enthusiasm that many products of the anti-theft lock core enterprises have made progress, especially in the appearance packaging and structural design. However, there is not much improvement in the most critical precision of the lock cylinder, and even some retreats are empty. When talking about the anti-theft level, the old people are somewhat disappointed. Many professionals currently use A-level, B-level, and C-level to promote and influence users on a one-sided basis, turning the level into a commercial operation, and turning it into a tool for users. It is very wrong to educate the user about the knowledge of the lock core product. The correct approach should be to tell the user in a real scientific way: what kind of materials should be used, what can be done to make a good lock core? The following is what Chen Daren told you.

What kind of lock cylinder is a good lock cylinder:

1, look at the material - the best choice of nickel alloy or stainless steel material to make the key, lock the lock cylinder

The lock core is based on precision to improve the anti-theft performance. The precision of the lock core requires good materials to ensure. Imported lock cylinders, some domestic high-standard lock cores (such as multi-colored lock cores, etc.) enterprises use nickel alloy materials (domestic called white copper, nickel 10%, manganese 2% or more, less than this ratio of materials can not do a good job The lock core.) The key embryo and the lock nail, because the hardness, toughness and wear resistance of this material are small, the coefficient of thermal expansion and contraction is small, and the shrinkage of the lock pin is not shortened because of the cold and hot weather. It becomes smaller, expands bigger and longer, affects the anti-theft performance of the lock core and the stability of the product. The key embryo will be more wear-resistant. If the key is easy to wear, the anti-theft performance of the lock core will be greatly reduced. If other materials are used: such as copper, iron, aluminum alloy materials for locking nails, key embryo quality, performance is not guaranteed.

A good lock core material is very important, consumers will learn it a little bit.

2, look at the structure - the best choice of mixed structure lock core

The structure of the lock core is an important indicator of the anti-theft performance of the lock core. The rapid development of modern science and technology has promoted the development of ** and the rapid improvement of locksmith unlocking technology. The technical limits of a single lock cylinder structure are difficult to cope with the challenges of unlocking technology (technical opening and breaking open). For example, although the ability of the sheet lock core to prevent the technology from opening is good, the ability to prevent damage is poor, and the T-tool is opened, because it is stuck in a V-shaped groove by a clutch lever. In the middle, the force lever is pulled out, and the clutch lever comes out from the V-groove, so it is opened. If the v-groove is processed into a U-shaped groove, it is more labor-saving.) In addition: the sheet lock cylinder is also afraid of high-frequency tapping. At high frequency tapping, the vane slots are easily aligned in the direction of the clutch lever, and the lock is opened. The idling lock also has technical limits. For example, it should not be idling and idling, and the lock cannot be opened. Another more critical problem is that some idling locks have structural drawbacks, and can be easily opened with a needle-like tool. This is very terrible.

The marble bead lock has a big advantage in the anti-vandal opening, but it has limited power in the face of advanced **.

Solving the anti-theft problem of the lock cylinder (anti-technical opening, anti-destructive opening, anti-structural opening), requires a hybrid structure to complete, which can solve the defects of a single structure. Such as: the combination of marbles and sheets, the combination of sheets and rotating beads. The multi-colored lock core adopts: finger-holding structure + mother-child double-bead structure + splicing structure, and the rationality of the multi-colored lock core structure is one of the few products in the hybrid structure products appearing on the market. The anti-theft capability of this combination is relatively high, and the anti-technical opening, the explosion-proof force opening, and the special tool opening effect are quite good.

The hybrid structure and the single structure can be seen at a glance from the key, and no experience is required here.

3, look at the accuracy - processing accuracy is the guarantee of the performance of the anti-theft lock, there is no precision structure, no structure can be discussed.

The imported lock core is more accurate than the domestic product win. The accuracy of a good lock cylinder is quite strict. Under normal circumstances, the lock nails and accessories need to be finished by standard finishing. Accuracy requirements are within the error: plus or minus 0.015MM; the error of the space between the lock core and the lock cylinder is also within 0.015MM. If this requirement is not met, the anti-theft performance will be greatly reduced. Imagine: Under such precise conditions: can the tin foil plug in and lock open?! Do you still need to put lead powder?! Of course, if the key is not accurate enough, the lock can't be opened, so sometimes we can see from the key. The accuracy of the lock cylinder. Looking at the structure and keys of the multicolored lock core, it is not difficult to find that the precision of the multicolored lock is no less than that of the imported brand.

On the other hand, I want to tell you that the precision of the lock nails that are punched out cannot be up to standard, and the anti-theft performance of the lock core must be problematic.

A person teaches a method: to check the accuracy of a lock, you can also slowly remove the key, shake the key up and down, and slowly pull it out. If the ** is pulled or pulled out, it has a feeling of elastic obstruction. The shaking feeling is not too big, and the accuracy of the lock cylinder is high. It is a good lock cylinder, but it must not be a good lock cylinder.

4, look at the anti-drilling bolt - lock core anti-drilling piece anti-drilling bolt is an important line of defense anti-destruction opening.

In view of the characteristics of the material of the lock cylinder core copper, if the protection measures are not taken, the drill bit is drilled and the lock core is immediately drilled through, and the lock core is protected against the drill bit. of. Implanting the anti-drill bolt and the drill-proof piece made of manganese steel at the key position of the front end of the lock cylinder can effectively prevent the lock cylinder from being drilled. Any anti-theft lock cylinder that does not make anti-drilling bolts is unsatisfactory, and it is not qualified to talk about the B-class super B-class lock cylinder.

5, look at the key protection measures - the key is not protected by the key card is not responsible for the safety of the user.

The development of modern science and technology, take a photo as you like. It is very dangerous to put the lock cylinder and the key card casually. The thief can take a key and a key card at any time and configure the same key. The multi-colored lock cans packaging has made a great contribution to the industry.

6, look at the lock core structure and description - the lock core structure is not disclosed sometimes there are structural defects.

It is very important for consumers to understand the technical structure of the anti-theft lock cylinder, processing precision, materials and other materials. The merchant is obliged to tell the user truthfully, what is the technical information of the structure, precision and materials of your product, because he is related to The security issue of the user's family needs to be responsible for the notification. Under normal circumstances, manufacturers have video and plane data to introduce the structure and working principle of the lock cylinder. Products that are not publicly available sometimes have security vulnerabilities that are not convincing. This must be noted.

Choosing a good lock core is a very simple thing, but it has become very difficult for many consumers. The problem is that some businesses and some people deliberately make things complicated and people can’t understand. For some of the smart locks have their consumption stage, consumers still need to open their eyes to see clearly, a good smart lock, it is very important to have a good lock cylinder.
