With the improvement of people's living standards, people pay more attention to the safety of life and property in modern life. Therefore, the application of anti-theft doors has increased. At the same time, other locks are also increasing day by day. Among them, idle locks are one of them. What? It is an idle lock. What is the principle of an idle lock cylinder? Let me introduce it to you below!

1. What is an idle lock?
The so-called idle lock mainly refers to its high anti-theft safety factor. If a thief goes to try to open the door lock, the idle lock will It will only idle but will not open. You must match the key before you can twist the lock cylinder to open it. The idle lock prevents theft to a certain extent. It uses the synergistic effects of the key, blocking column, slider, clutch spring and return spring to realize the clutch between the dial block and the lock core.
2. Characteristics of the idle lock
The lock cylinder of the idle lock can be rotated by some tools, such as iron wire, screwdriver and iron sheet, but the lock cylinder will only keep turning. The lock cannot be opened if it is idle. Only the correct key can be used. And the idle lock has good anti-prying, anti-drilling, and anti-opening technology. Idle-turn locks are currently a relatively advanced type of lock and are also relatively popular among consumers.

Principle of idle lock
An idle lock includes a shell, a key, a lock cylinder, a blade, a dial and a gear with teeth on the inside. slider. (The structure is slightly different due to different manufacturers.)
The lock cylinder is provided with an inner cavity that is connected to each blade slot and houses a sliding plate. The side of the sliding plate is provided with a tooth opening corresponding to the blade slot. The surface of the lock core is also provided with a marble hole that intersects perpendicularly with the inner cavity and the keyhole. The lower end of the marble with an annular groove on the surface extends into the marble hole of the lock core and then passes through the through hole on the slide plate and then extends in. In the key hole;
The tail of the lock cylinder is covered with a second lock cylinder; a radial ball hole is opened at the tail of the lock cylinder, and accordingly, a clutch hole is opened on the wall of the second lock cylinder, and a clutch hole is opened on the wall of the second lock cylinder. There is a flat ball hole on the top, and the ball is placed in the ball hole. The clutch ball is placed in the channel composed of the ball hole, the clutch hole, and the flat bead hole. The flat ball is placed in the flat bead hole, and a clutch is set between the outer end of the flat ball and the shell. The length of the spring and the clutch ball is greater than the wall thickness of the second lock core; the position where the rear end of the slide plate contacts the ball is a slope.
When unlocking, insert the key, and each blade and marble will be pushed to the unlocking position by the key. At this time, the notch on each blade is facing the teeth on the side of the skateboard and will not block the sliding of the skateboard back and forth. The annular groove on the marble is just at the through hole of the slide plate and there is a certain gap between the annular groove of the marble and the slide plate. Under the action of the clutch spring, the force of the ball on the slope of the slide plate causes the slide plate to slide along the axis of the lock core. a distance so that the ball can move inwards.
Until the outer end surface of the clutch bead is flush with the outer cylindrical surface of the second lock core, the clutch bead spans between the ball hole of the lock core and the clutch hole of the second lock core to make the lock core and the third lock core The two lock cylinders are connected, and turning the key can cause the lock cylinder to drive the second lock cylinder to rotate relative to the housing, and the second lock cylinder drives the locking mechanism in the door to unlock;
When locking, Turn the key back to the locked position in the opposite direction. During the process of pulling out the key, the pinball teeth on the key first push the pinball upward, and use the annular groove with a "V" shape on the pinball to reset the slider. The slope at the end of the slider The ball, clutch ball, and flat ball are forcibly reset, and the clutch ball straddles between the second lock core and the outer shell to connect the second lock core and the outer shell, thereby locking the second lock core in the outer shell and preventing the lock from being unlocked.
At the same time, the inner end surface of the clutch bead is flush with the inner cylinder surface of the second lock core. When the key is completely pulled out, each blade and marble are reset under the action of the leaf spring and marble spring, and the gap on the blade is in line with the inner cylinder surface of the second lock cylinder. The teeth on the skateboard are misaligned, and the annular grooves on the marbles are also misaligned with the through holes of the skateboard, causing the skateboard to be positioned and unable to move.
The idle-turn lock is a lock with better anti-theft performance at present. The idle-turn lock has better anti-theft performance than ordinary locks and is the latest patent. People can buy with more confidence~
