Classification of padlocks

Oct. 16, 2019

In addition to the classification of the high safety padlocks (straight open, horizontal open, open open, double open), we can also classify according to the internal structure of the padlock. The common ones are as follows:

1, marble structure padlock

Such a lock uses a cylindrical type of marble to set an obstacle in the lock cylinder, so that the lock cylinder cannot rotate and achieve the function of blocking. The marble structure is also one of the commonly used structures of locks. The lock body with a kind of lock is made up of metal sheets, which gives a thick and solid feeling. It is called "Millennium Lock", but its internal structure is also a marble structure, so it is also a marble structure type padlock.

2, blade structure padlock

Such locks use a variety of sheet metal to act as a barrier to latching, and such structures are often used in zinc alloys or their alloy locks.

3, magnetic structure padlock

According to the magnetic repelling principle, a magnetic lock core system is adopted, and a constant magnetic metal separator with the same magnetic plate as the key is installed between the lock cylinder groove and the safety pin, and the key and the safety pin are not in direct contact, when the slotless magnetic key When smoothly inserted into the lock cylinder groove, the key touches the metal partition, which generates a strong repulsive force and opens the lock easily. In addition, the principle of magnetic attraction is used to suck the metal plate and open the lock by the spring.

4, chain structure padlock

It consists of a primary lock and a secondary lock. The primary and secondary locks have mutual protection and are related to each other. When the two sub-locks are connected, the main lock is locked. Only after the two sub-locks are opened and removed, the main lock can be opened.

5, number structure padlock

A lock mechanism is arranged on the lock body of the lock, the hole is connected with the slot, can be moved and rotated, and the dial is connected with the rotator. The rotator is equipped with a tooth-shaped or cam-shaped metal blade, which can be rotated and moved, as long as the number is dialed. The lock can be opened by itself. This type of lock has no key.
