This is the principle of unlocking

- Sep 23, 2017 -

In the circular lock heart drilling a few holes, and then in the lock hole with the hole at the corresponding location of the lock also drilled the same number and diameter of the same small hole. The role of the hole is used to pack the ball and spring. (The small hole in the lock is used to load the ball and spring, and the heart of the lock hole called the ball). Usually, we put the lock and lock the heart of the hole called the hole hole. So, the role of the ball is used to hold the lock heart, so that the lock heart can not just turn. Therefore, regardless of the shape of the lock and lock the body within the different how, but for the unlock principle plays a major role is the lock heart, marbles and springs. When the lock body of the ball hole and the lock heart of the box hole completely coincide, the lock body hole spring to play the role of elastic, the lock ball hole hole out of the ball. The ball in the hole is pushed into the lock hole. The original marbles in the center of the lock heart are raised at the same time. As the lock center keyhole has a block to lock the heart of the ball within the ball box, so that the ball is not the top of the ball out of the hole, take off. When the manufacturer produces the lock, the length of the ball and the depth of the lock hole are calculated. Generally must be the length of the two balls in the hole and the center of the lockball hole and the length of the length of the long ribs. And the length of the ball in the center of the lock heart must be greater than one third of the length of the slender hole. In this way, the lock hole in the hole of the ball hole with a long ribs stuck without the top out of the ball hole, and that lock the ball hole in the spring under the role of a part of the length of the jack into the lock hole hole. Lock the ball hole in the box into the lock heart of the ball is to lock the heart stuck, so stuck a circular object, so that round objects can not turn freely. At this point, the lock is in a locked state, is usually said "locked". However, after the extension of the key into the lock keyhole, the key on the cave to lock the heart of the ball is also down the ball down, just to lock the heart of the ball box full of overwhelms, flatten the heart of another hole The mouth of the mouth, (lock heart of the hole and the mouth of the mouth of the mouth of the contact surface), then lock the ball hole all the ball because the lock heartball hole within the ball down the role of pressure, all were flat Lock the ball hole, back to the lock body hole. At this time, the shells of the ball can not be inserted into the lock hole in the hole, the lock heartball hole was pressed under the ball can not be pressed into the lock body of the hole, that is not something stuck round Lock heart. And then you can use the key to turn the lock heart to turn, lock the heart after the rotation is to drive the body inside the lock, the lock open. This is the principle of unlocking. So, as long as the circular lock heart lock lock the same principle
