In addition to the classification of open padlocks (straight open, horizontal open, top open, double open), we can also classify padlocks according to their internal structure. The common ones are the above:
1.Padlock type padlock
This type of lock uses a cylindrical marble to set an obstacle in the lock core, so that the lock core cannot rotate and achieves the function of locking. The marble structure is also one of the structures commonly used in locks. The lock body of some locks is made of metal sheets stacked on top of each other, giving a thick and solid feel. It is called a “thousand-layer lock”, but its internal structure is also a marble structure, so it is also a marble structure type padlock.
2.Padlock padlock
Such locks use sheet metal with various shapes to act as obstacles and to achieve the purpose of locking. Such structures are often used in zinc alloy or word alloy locks.
3.Padlock with magnetic structure
Based on the principle of magnetic repulsion, a magnetic lock core system is adopted. A permanent magnetic metal partition with the same magnetic plate as the key is installed between the lock core groove and the safety pin. The key does not directly contact the safety pin. When smoothly inserted into the lock cylinder slot for rotation, the key touches the metal partition, creating a strong repulsive force, and the lock can be easily opened. In addition, the principle of magnetic phase suction is also used, the metal plate is sucked tightly, and the lock is opened by the spring.
4, Chain structure padlock
It is composed of a main lock and a sub-lock. The main and sub-locks have mutual protection and are related to each other. The main lock is locked by connecting two auxiliary locks. The main lock can only be opened after the two auxiliary locks are opened and removed.
5.Number structure padlock
A slide mechanism is installed in the lock body shell of the lock. The hole is connected to the slot, which can be moved and rotated. The dial is connected to the rotator. The rotator is equipped with tooth-shaped or cam-shaped metal blades, which can be rotated and moved. , The lock can be opened by itself, this type of lock has no key.
