We know that each type of lock has certain differences in structure, which in turn determines the functional differences between them, such as keyed padlocks, wire locks, ring locks, chain locks, folding locks, wire locks, joint locks, discs brake, etc.
However, from the perspective of the principle of unlocking, the unlocking principle of most locks is similar. Of course, special locks such as electronic locks, magnetic locks, and fingerprint locks cannot be counted here.
Although the styles, structures, sizes, and keyholes of locks such as cable locks, ring locks, chain locks, folding locks, line locks, joint locks, and disc brakes are different, the unlocking principles are similar.
Generally, locks are mainly composed of a lock body and a lock cylinder. As long as the lock is composed of these two parts, no matter whether the types of locks are similar or not, the unlocking principle is similar, mainly because their lock cores are all around. Shaped objects, the lock is opened like this, as follows:
When there is no key, push down the blue flat ball (also called lock spring or bead) inside the lock, so that the lock cylinder cannot rotate, and when we put the correct key, the blue flat head marble and The spaces between the red lower marbles (also called lower springs or lower beads) line up and align with the yellow lock cylinder. When the space between the marbles is aligned with the transition line, the yellow lock cylinder can be opened.
