What is the best thing about the lock core made of copper

The structure of frequently used locks can be described as complicated. The structure of a general lock consists of a lock cylinder, a billiard, a spring, a tongue, a key, etc. This kind of lock is one of the most commonly used locks. It is simple to connect the material and structure of the lock core.

Nowadays, most lock cores are made of hard metal. The locks used by people in daily life are made of copper. Copper is not easy to rust, and copper and iron and other metals will not stick together. Copper is relatively hard and has good toughness, not easy to break. This is why copper was chosen as the lock cylinder.

Another advantage of using a copper wall lock core is that it is not easily oxidized. Even if the lock of the copper lock is hung in the open air and 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, motor oil, preferably sewing machine oil) can be opened a few times The function of using the lock is restored as before.

The lock core has several small holes drilled in the circular lock core, and then the same number of small holes with the same caliber are drilled in the lock body position corresponding to the small lock hole. Usually, we call the small holes in the lock body and lock core the pinholes.

Then, the function of the marble is to catch the lock core, so that the lock core cannot rotate casually. This construction principle is easier to use the lock.
