Household fingerprint lock purchase considerations

Things to be aware of when purchasing a fingerprint lock:

Standard 1: When purchasing a fingerprint lock, be sure to understand whether the fingerprint lock brand has a national after-sales service point, and promise to provide a solution to the problem 24 hours a day. When choosing and buying fingerprint locks and smart locks, we consider several fundamental factors such as certification, design, function and after-sales service.
Standard 2: There is no multi-point lock protection and sufficient strength of the lock tongue protection. Most fingerprint locks are single-lock tongues. They are not suitable for Chinese people, easy to be opened, or fail to achieve anti-theft and anti-riot performance. The fingerprint lock with multi-point lock tongue is by far the most superior and the highest security performance.
Standard 3: When selecting the fingerprint lock, it is necessary to know whether the fingerprint lock has the function of the insurance tongue and the anti-insertion. First, the motor will enter the closed state after opening the door. Second, it has the insurance tongue. After the door is closed, the safety tongue acts, and the tongue is combined with the tongue. Can not be pressed in again, anti-insertion, anti-mite, anti-theft effect, theft can eliminate this safe after-effects, use more assured. Of course, some locks close the door and the tongue automatically pops out. In the past, it is analyzed by experience. This type of structure has a bad side. If the gusset is not well matched, or the body, luggage, etc. first touch the tongue, first pop the square tongue. I don't know, if you close the door again, it will become a damage to the lock body.

Carbon Steel Bolts

This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
