In addition to the classification of padlocks according to the opening method (straight opening, horizontal opening, top opening, double opening), we can also classify the padlocks according to the internal structure of the padlocks. The common ones are the above types: 1. Marble structure padlocks
This type of lock uses a cylindrical pin to set up obstacles in the lock core, so that the lock core cannot be rotated and achieves the locking effect. The marble structure is also one of the commonly used structures of locks. There is a kind of lock whose body is made of metal sheets stacked on top of each other, giving people a thick and sturdy feeling. It is called a “thousand layer lock”, but its internal structure is also a marble structure, so it is also a marble structure type of padlock.
2. Padlock with blade structure: This type of lock uses flake metals of different shapes to act as an obstacle for the purpose of locking. This type of structure is often used in zinc alloy or alloy locks.
3. Magnetic structure padlock: According to 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 slot and the safety pin, and the key and the safety pin do not directly contact. , When the slotless magnetic key is smoothly inserted into the lock core slot and rotated, the key touches the metal partition, generating a strong repulsive force, and the lock can be opened easily. In addition, the principle of magnetic attraction is used to close the metal plate and open the lock with a spring.
4. Chain structure padlock: It is composed of main lock and auxiliary lock. The main and auxiliary locks have mutual protection and are interrelated. Connecting two auxiliary locks will lock the main lock. The main lock can only be opened after opening and removing the two auxiliary locks.
5. Number structure padlock: A sliding plate mechanism is installed on the lock body shell of the lock. Its hole and groove are connected, which can move and rotate. The dial is connected with the rotor. The rotor is equipped with tooth-shaped or cam-shaped metal blades, which can rotate and rotate. Move, as long as dial the correct number, the lock can be opened by itself, this kind of lock does not have a key.
