Description
Technical field
The utility model relates to a kind of theftproof lock, is meant a kind of lock core body, turning cylinder and clutch unit of comprising especially, and this clutch unit is that this lock core body that is provided with between this lock core body and this turning cylinder can be with respect to the theftproof lock of this turning cylinder idle running.
Background technology
As everyone knows, each is locked in the textural difference that all has, and this has just determined the difference of its function.For the principle of unblanking, the principle of unblanking of most locks is identical.General lock, as the common door built-in lock, padlock, the computer spoon, cross door built-in lock etc., though their pattern, structure, size, the key aperture is inequality, the principle of unblanking is identical.
On the lock core of circle, be drilled with several little holes, also boring similar number and the same little hole of caliber size with the lock body position of corresponding position, lock core duck eye hole again.The effect of little hole is to be used for shooting son and spring.(lock little hole on one's body is used for shooting son and spring, and the hole on the lock core is referred to as pellet shot from a slingshot).Usually, our a little hole of locking on body and the lock core is referred to as the pellet shot from a slingshot hole.So, the effect of pellet shot from a slingshot is to be used for blocking lock core, and lock core can not at will be rotated.Therefore, no matter lock how inequality of the external form of body and the office of lock in the body, but what bringing into play main effect for the principle of unblanking is lock core, pellet shot from a slingshot and spring.When the pellet shot from a slingshot hole of lock body overlapped fully with the pellet shot from a slingshot hole of lock core, the spring performance elastic force effect in the lock body pellet shot from a slingshot hole upwards ejected the pellet shot from a slingshot in the lock body pellet shot from a slingshot hole.Pellet shot from a slingshot in the lock body pellet shot from a slingshot hole by jacking in the lock core marble hole.Original pellet shot from a slingshot is upwards pushed up at one time in the lock core marble hole.Owing to have a long raised line to block in the lock core keyhole, stop the pellet shot from a slingshot in the lock core marble hole, pellet shot from a slingshot is not ejected outside the pellet shot from a slingshot aperture, take off out.
After stretching key and entering lock core keyhole, teeth groove on the key the pellet shot from a slingshot of lock core marble in also to lower compression, just the pellet shot from a slingshot total head in the lock core marble hole is fallen, flatten the place, another side aperture of lock core marble hole, (lock core marble aperture and the contact surface of locking body pellet shot from a slingshot aperture), at this moment lock in the body pellet shot from a slingshot hole all pellets shot from a slingshot since by pellet shot from a slingshot in the lock core marble hole to the effect that presses down, also all be driven plain lock body pellet shot from a slingshot aperture, get back in the lock body pellet shot from a slingshot hole.At this moment, the pellet shot from a slingshot in the lock body pellet shot from a slingshot hole can not stick in the lock core marble hole, and the pellet shot from a slingshot that is pressed down in the lock core marble hole can not be depressed in the pellet shot from a slingshot hole that enters the lock body, has not had thing to block circular lock core in other words.Available then key reverses lock core and rotates, and then drives the office in the lock body after lock core rotates, and lock is opened.This is the principle of unblanking.Aforesaid traditional lockset when lock core by special instrument when keyhole is inserted and rotated, the pellet shot from a slingshot that stops lock core to rotate can be twisted off, and makes lockset by unnormal unlocking, thereby loses anti-theft feature.
