Due to the structural characteristics of the padlock, it is determined that the padlock is convenient and flexible to use and has a wide range of uses.

The function of closing and opening inside and outside, so it cannot be used in some occasions. For example, in some occasions with high decorative requirements or matching locks, it is generally not suitable to use padlocks.

Classification method of padlocks There are many varieties and specifications of padlocks. Generally, the size of the lock is determined by the width of the lock body, the use of the lock is determined by the height of the lock beam, and the lock is determined by the straight opening, horizontal opening, top opening, and double opening of the padlock. series.

Our commonly used padlocks generally use straight opening and horizontal opening.

That is, when the key is inserted into the key slot of the lock cylinder, the lock that can be pulled upward without turning is called “top unlock”. This type of padlock is especially suitable for openers who hold babies or carry items that are not suitable for putting down. The so-called “double-opening padlock” refers to a lock that requires two keys to open when it is opened. It has strong confidentiality and is suitable for occasions where two people are required to keep the lock and two people are present at the same time to open the lock, such as warehouses, silver vaults, etc.

Internal structure classification

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

1. Ball structure padlock

This type of lock uses cylindrical marbles to set obstacles in the lock cylinder, so that the lock cylinder cannot be rotated and achieves the effect of locking. The marble structure is also one of the commonly used structures in locks. The lock body of a kind of lock is made of overlapping metal sheets, 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 padlock.

2. Blade structure padlock

This type of lock uses sheet metal with different shapes to play a barrier role and achieve the purpose of locking. This kind of structure is often used in zinc alloy or its alloy locks.

3. Magnetic structure padlock

According to the principle of magnetic repulsion, a magnetic lock cylinder system is adopted. A permanent magnetic metal partition with the same magnetic plate as the key is installed between the lock cylinder slot and the safety pin. The key and the safety pin are not in direct contact. When it is smoothly inserted into the slot of the lock cylinder and rotated, the key touches the metal partition, which produces a strong repulsive force, and the lock is easily opened. In addition, the principle of magnetic attraction is also used to tighten the metal plate, and the lock is opened by the spring.

4. Chain structure padlock

It consists of a main lock and a secondary lock. The primary and secondary locks have mutual protection and are related to each other. Connecting two auxiliary locks locks the main lock. Only after opening and removing the two auxiliary locks, the main lock can be opened.

5. Number structure padlock

A sliding plate mechanism is installed in the lock body shell of the lock. The hole and the slot are connected, which can be moved and rotated. The dial is connected with the turner. , the lock can be opened by itself, this type of lock does not have a key.
