We know that each type of lock has a certain difference in construction, which in turn determines the functional differences between them, such as cable locks, loop locks, chain locks, folding locks, Wire lock, joint lock, disc brake lock, etc.
However, from the perspective of the principle of unlocking, the principle of unlocking most locks is similar. Of course, special locks such as electronic locks, magnetic locks, and fingerprint locks cannot be counted here.
Although the style, structure, size, and keyhole of locks such as steel cable locks, ring locks, chain locks, folding locks, wire locks, joint locks, and disc brakes are not the same, the principle of unlocking is similar.
Generally, the lock is mainly composed of a lock body and a lock cylinder, and as long as the lock is composed of these two parts, regardless of whether the types of the locks are similar, the unlocking principle is similar, mainly because their lock cores are all round. Shaped objects, this type of lock is so open, as described below:
When the key is not placed, the blue flat ball inside the lock (also called the upper lock spring or the upper bead) is pushed down so that the lock cylinder cannot rotate, and when we put the correct key, the blue flat head The vacancies between the marbles and the red lower marbles (also called the lower lock springs or the lower beads) are in line and aligned with the yellow lock cylinder. When the vacancies between the marbles are aligned with the transition line, the yellow lock cylinder can be turned open.
