The open-type safety padlock structure, the lock cylinder core axis and the lock line straight line of the vertical axis, the head is an eccentric pin, by the eccentric shaft pin residential area lock beam. When the lock is required to open, the key will be inserted into the lock cylinder rotation, lock cylinder and key together to rotate, tighten the return spring, lock cylinder to a certain angle, the eccentric pin to eliminate the lock beam of the role of the lock beam in the spring force Under the action of the pop-up, playing to a certain height was beam stopped, the lock was opened.

When the lock beam jumps, the lock cylinder on the eccentric locking shaft was the obstruction of the lock beam, so that the cylinder can not return to the original position, the key in the cylinder was back to the ball can not pull the obstacles, people call this The phenomenon is "the general does not dismount".

When the lock needs to be closed, with a straight-type safety padlock to close the way to put pressure on the lock, lock beam compression spring into the lock body, into the locked position, the clamshell to eliminate the cylinder core eccentric pin obstacles, The role of the spring back to the original position, eccentric pin will be locked beam sales, to achieve the purpose of locking.

The lock has the advantages of simple structure, low price, easy to lose key and so on. But there is also a fatal flaw is low degree of solid, poor anti-theft performance. As the lock beam is single-sided locking, it is easy to pry the non-locking surface, so that the lock beam was destroyed.

In recent years, many consumers are constantly open to unlock the manufacturers are actively discuss how to progress the degree of opening the degree of open, and consumption of the gap with the security of the padlock. The lock in the original cross-unlock on the foundation to increase the oblique pin, spring, latch, seal four parts, and the lock manufacturing process has little effect.

When the lock needs to open, the key will be inserted into the lock cylinder rotation, the lock cylinder eccentric pin loss of the lock beam of the ban, the lock side of the square tendons on behalf of the oblique pin to move up, with inclined to push the tongue, , Revoked the lock beam of the ban, the lock beam in the role of the elastic jump up, jump to a certain height after the beam was stopped.

When the lock demand is closed, press the open-type safety padlock to close the applied pressure, the lock beam tightening spring into the lock body, the lock cylinder under the action of the return spring reset, on behalf of the oblique lock down movement, the tongue under the action of the elastic Outside the lock, the lock beam is forbidden, lock core head of the eccentric pin is also sold at the same time lock the lock beam, so that the degree of solid than the original hanging lock lock a lot of progress.
