Unlocking, that is, the meaning of opening the lock, unlocking has formed an industry, and there is a professional locksmith qualification certificate.

Each kind of lock has differences in structure, which determines the difference in its function, for the principle of unlocking, the principle of unlocking the vast majority of locks is the same, except for some locks such as magnetic card locks and electronic locks.

Door locks, sliding door locks, cross-type door locks, etc., although their style, structure, and size are different, the principle of unlocking is exactly the same.

As the saying goes, everything is the same, the main reason why these locks are exactly the same is that their locks are all round objects, and those who have studied physics know that only round objects can rotate freely. Square and flat are objects that cannot be rotated at will.

Having discussed so much, the principle of unlocking the lock is actually based on the core of this round object.

First of all, the lock cores are made of harder metal. So, why are the locks used by people in daily life made of copper, and there is a certain reason for using copper hearts. Copper is not easy to rust, copper and iron and other metals will not stick to each other, copper is relatively hard, and has good toughness, not easy to break.

There are also a few manufacturers who use stainless steel to make lock cores, and the cost of stainless steel is high, which is not adopted by general manufacturers. However, in order to save materials and reduce costs, some manufacturers use aluminum alloy copper plating to make the lock core, which causes the lock to be easy to break, which is not desirable.

Even if the lock of the copper lock core has been hung in the open air and been exposed to the sun and rain for a long time, although it is not easy to open, as long as a few drops of lubricating oil (such as kerosene, engine oil, preferably clothes car oil) are opened, the function of the lock can be restored to the original state.

Secondly, drill a few small holes in the circular lock core, and then drill the same number of small holes and the same caliber size in the lock sail trembling body position corresponding to the small hole in the lock core, the function of the small hole is to hold marbles and springs, and the small holes in the lock body are used to hold marbles and springs, and the holes in the lock core are called marbles.

Usually, we refer to the small holes in the lock body and lock core as the bullet hole. Therefore, no matter how different the appearance of the lock body and the mechanism in the lock body are, it is the lock core, the bullet and the spring that play a major role in the unlocking principle.
