The padlock is mainly composed of a lock core, a lock tongue spring. A lock core and a row of holes through the lock body, each of the holes in the top with two springs. When a key is inserted into the two ball, each hole is divided in the lock core and the
lock body combination between both sides, so as to drive the lock tongue sliding, so the lock opened. When the key is pulled out or inserted into other keys, a key role in the spring and uneven with the lock core and the lock body between the
combination surfaces, therefore, the lock core cannot rotate, the lock is not open. All of the marbles as long as there is a lame in the lock core and the lock body on the interface between the lock cannot be opened.
The role of the spring in the padlock:
The spring top with a marble in padlock, the marble if do not top with the key tooth will stuck the lock core to prevent rotation. When the key inserted into the key hole, if that is the right key, then the ball is the top, the lock core can be rotated. Spring
padlock in the role is responsible for the outward top cylinder to cylinder locking core. The role of the spring in the padlock is responsible for the outward top cylinder to cylinder locking core.
Classification and function principle of padlock
Padlock’s classification except according to open the way (straight, horizontal, open top, double), we can also classify according to the inner structure of padlock, common to have more than a few:
Leaf structure of padlock：This kind of lock using sheet metal shapes of obstacles, to lock, this kind of structure always be used in zinc alloy or other alloy lock.
Padlock serial structure: Padlock comprises a main lock and the secondary lock, the main and the secondary locks have mutual effect. Connecting two side lock will set the main lock, only open and remove the two side lock, then the master lock can be
The magnetic structure of padlock: Based on the magnetic repulsive function principle, adopts magnetic lock core system, with the constant magnetic metallic partition board with a key with a magnetic plate between the lock core groove and a safety pin, no direct contact with the key and the safety pin, when no magnetic key smoothly inserted into the lock core groove rotates, the key touch the metal separator, produce a strong repulsive force, the lock is easy to open.
In addition, also by using the principle of magnetic attraction, the metal plate is tightly attracted, by spring open the lock.
Marble structure function principle: class padlock padlock, is the oldest and most large family locks in the world, it can be said that other locks are multiply derived from this category to padlock. The lock body is provided with a padlock can be buckled annular or "one" word shape metal stalk, namely "the lock beam, the lock beam padlock through" direct and the lock body buckled become enclosed locks.
The number of structure function principle: in the padlock lock body shell device for lock a slide mechanism, the holes and slots are connected, can move and rotate, number plate and rotating device connected with the rotating device is provided with a tooth shaped, or cam shaped metal blade, can rotate and move, as long as the set number, which can be to open the lock, class lock without key.
