Here to analyze the material and the structure of a lock core, the direct effects of material and structure of the lock core to the safety of the lock core and lock the quality evaluation.
The lock core material: now the lock core are used to make hard metal, people in daily life by using lock are made of copper, copper is not easy to rust, copper and iron and other metal will not stick junction adhesion. Copper hard, and good toughness, and not easily broken. This is why selected for copper for the reason of the lock core. The wall of the lock another advantage is not easy oxidation. Copper core lock even hung in the open air to be exposed to the sun and rain for a long time, although not open, but as long as a few drops of lubricant (such as kerosene, engine oil, it is best to sewing machine oil) activities on a few can use the lock function recover.
The structure of the lock core of the lock core drilling in the round: there are several small holes, and then in the lock body corresponding to the location of small holes and lock the same number and size of drilling small holes. Usually, we put a lock body and a lock on the small holes called marble hole. Then, the marble is used to lock the lock core can not get stuck, rotation, using the structure principle of such easy to lock.
