Due to the structural characteristics of the padlock, the padlock is convenient and flexible to use and has a wide range of uses. It can replace other locks, and other locks can not replace the padlocks. It is an ideal anti-locking device, but the padlock must be interlocked with the convex holed parts of the closed object to play the latching effect. The function of closing and opening can be used inside and outside, so it can not be applied in some occasions. For example, in some occasions where the decorative requirements are high or the supporting locks are required, it is generally not suitable to use the padlock. Padlock classification method There are many varieties and specifications of padlocks. Generally, the size of the lock is determined according to the width of the lock body. The use of the lock is determined according to the height of the lock beam. The lock type is determined by the opening mode of the padlock, the horizontal opening, the top opening, and the double opening. Our commonly used padlocks generally use straight opening and two opening modes. That is, when the key is inserted into the key cylinder of the lock cylinder, the lock that can be pulled upward without rotating is called “top open lockâ€. This type of padlock is especially suitable for carrying the baby or carrying the opener who is not suitable for putting down the item. The so-called "double-open padlock" refers to a lock that requires two keys to work when it is opened, and it can be opened. It has strong confidentiality and is suitable for occasions where two people need to keep it. When two people come to the scene to open the lock, such as warehouse, silver library, etc. Classification of padlocks In addition to the classification of the 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: Bullet 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 strong feeling, called "Thousand Layer Lock", but its internal structure is also a marble structure, so it is also a marble structure type padlock. 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. 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. Chain structure padlock It consists of a primary lock and a secondary lock, and the primary and secondary locks have mutual protection. 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. Number structure padlock A lock mechanism is arranged on the lock body of the lock, the hole is connected with the groove, 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.
