Smart locks are one of the hottest products in the field of smart homes in the past two years. Many lock brands, Internet companies, traditional home appliance companies, entrepreneurs, etc. have invested in the blue ocean of smart locks. However, no matter how powerful the smart lock is, it must first be a good home door lock, anti-theft, safe, and reliable in quality. Under the current chaos in the smart lock industry, some manufacturers do not necessarily meet the most basic needs of consumers. The smart door lock body is the core component of a smart door lock, which determines whether the fingerprint lock has higher security capabilities and is the fundamental core of whether the fingerprint lock is safe. So how do we judge the quality of a smart door lock body? Below we also analyze from 4 points. 1. Unlock body function One function that the fingerprint lock body must have is the fireproof function, which is mainly reflected in the material selection and lock body structure design. It is necessary to ensure that the lock body structure is still complete and the function can be used normally in the event of a fire. If the lock body is stable, the display will be more perfect if you have other functions, such as the lock body self-bouncing function, anti-saw function, etc. 2. About the material The lock body includes the main body, the bolt and the lock cylinder. The main body of the fingerprint lock body is made of zinc alloy and stainless steel. The abrasion resistance and impact resistance of zinc alloy are far inferior to stainless steel, and it is easy to deform, so the seller The lock body of stainless steel should be selected, and 304 stainless steel is best; the lock tongue is one of the main parts of bearing force, it must be strong and reliable, and 304 stainless steel is also preferred; the lock cylinder is the core part of the lock body, which requires wear resistance, It is resistant to impact and rust, so the lock cylinder is generally made of pure copper. 3. The lock cylinder is the key The lock cylinder is the key to security performance. The above mentioned that the lock cylinder is preferably made of pure copper, and the type and level of the lock cylinder are more important. The security level of the lock cylinder I have mentioned above, the smart door lock must reach the level of A-level, B-level and super-B level. 4. Lock tongue The lock tongue is the main load-bearing component, it is better to use stainless steel, and it must be solid. The quality of the lock tongue depends on the structure of the lock tongue. Generally, the electronic lock body has four tongues and five tongues, and the Bawang lock body uses double hook bolts. No matter what the structure, it is best to have more locking points, that is, when someone breaks through a bolt, other bolts do not retract with the linkage, so that they can continue to be placed. We also talked about the rating of the lock cylinder above. The lock cylinder is also the most obvious and important part of checking the safety of a home door lock. Currently, the Ministry of Public Security has three levels: A, B, and C. Class A lock cylinder Very low safety factor In terms of destructive unlocking time, anti-drilling, anti-prying, anti-pull, anti-shock for more than 10 minutes, anti-saw for more than 5 minutes; technical unlocking time for more than 1 minute. The destructive resistance is very poor. The key types are flat or cross-shaped keys. The structure of this lock is very simple, only five or six marbles are needed. The price is very low, and the safety factor is also very low. It is mostly used for wooden doors or iron doors in old communities. The marble structure is very simple, it can be opened in minutes with a tin foil tool, and it will not make a sound when it is opened. This kind of lock can not only be opened instantaneously, but also will not damage the lock and is not easy to be found by others. Class B lock cylinder Relatively high safety factor In terms of destructive unlocking time, anti-drilling, anti-prying, anti-pull, anti-impact for more than 15 minutes, anti-saw for more than 5 minutes; technical unlocking time for more than 5 minutes. Key types: semi-circular single-row keys or double-row blade keys. The structure is more complicated than a single row pinball lock, and it is difficult to unlock the lock. The safety factor is higher than that of the flat key lock, and the tin foil tool can also be opened. Part of the self-styled super B-class lock core products, the double-row blade key has double-row marbles on one side, and double-row blades on the other side, which can prevent violent unlocking, has a high safety factor and a moderate price. C-level lock cylinder The safety factor is very high, but it is not impossible to crack. In terms of destructive unlocking time, the anti-drilling, anti-saw, anti-pry, anti-pull, and anti-impact time are all over 30 minutes; the technical unlocking time is over 10 minutes. It is said that the anti-theft unlocking time of some C-class locks can be as high as 400 minutes, which can be said to be very powerful. The key type is a crescent-shaped multi-row key or a three-row leaf key. All blade structure, the back is flat. There are three dimensions of "slot + pit + mysterious pattern" on it. It is said that there are still four dimensions of new product locks, and a plane has been added. This kind of lock has a very high safety factor. If the key is accidentally lost, it is basically difficult to open, and it is likely that the lock cylinder can be discarded to open. However, it does not have this problem when used on smart locks. It is enough to unlock the lock by swiping or fingerprint unlocking, and there is no need for a key. The price is of course higher. We can judge the safety factor and standard of the smart door lock through the certificate of the lock core rating given by the manufacturer after the inspection, and also make selection and judgment by observing the smart door lock body.
