How To Use A Combination Lock

You must have seen and used combination locks at your school or college lockers and know how easy they are to use. But have to ever think how they work and what is inside it. 

The Shackle

There is a casing on top which holds all the parts. On top, there is a metal curved bar which is called the shackle. It won’t come out until the right combination is put in. Then it pops right open. 

The Lever

Then comes the piece called the lever. It slides right onto the bar. The lever can rotate counterclockwise. Once it bends inside the tension makes the latch want to spring back to its original position. Normally the latch would just keep going, but the rotation will be stopped by the tiny bump.

The lever also has a tiny latch that is spring-loaded from the inside. The shackle comes down, pushes the latch in, and then the latch fits right into the groove, and it locks. when the shackle is pulled out the latch is forced to rotate to allow the shackle to come out. Then the lever springs back into place. 

The shackle can not come out because of the shackle collar. It escorts the shackle as it slides along. But it stops us once at the very top. 


The reason it works is that, if the latch can rotate, then the shackle won’t come out. The backplate has a bar sticking out. It clutches the three cams, washers in between, and a spring at the end. The spring makes sure the three cams and the washer are all pressed together. Cam 2 and 3 can spin freely. But cam 1 is attached to the dial. So when the dial spins it spins too.

Each cam has an indentation in them. The lock will open when all the camps are lined up. When they are not lined up, the lever won’t rotate. 


To use this kind of lock you need to set your combination. When you buy these locks they are set with 0’s combination. So to make them safer you need to reset that combination and shuffle the dial so no one can crack that lock and it remains safe.
