Description
Technical field
The present invention relates to a kind of improved lock core mechanism with lost motion functionality.
Background technology
Traditional lock core mechanism, generally all adopt upper and lower pellet shot from a slingshot or blade as Cipher mechanism, the structure design of simple upper and lower pellet shot from a slingshot is simpler and cruder, theftproof performance a little less than, and adopt blade as the lock core of Cipher mechanism, all be to lock by the blade of difference arrangement and the groove fit of lock core shaft's overcoat, its structure design is also more common, and the performance that anti-violence is opened is not strong yet; And in use, the key of insertion swings easily, and the feel of operation is not good, and comparatively speaking, fault rate is also higher.
Summary of the invention
In order to overcome the simplicity of design of the Cipher mechanism of common lock core mechanism in the prior art, the performance that anti-violence is opened is weak, the not good problem of feel of operation, the invention provides a kind of lock core mechanism with lost motion functionality, convenient, the anti-group performance that anti-violence is opened of the unlock operation of this lock core mechanism is strong, fault rate is low, good reliability.
The technical solution adopted for the present invention to solve the technical problems is: comprise lock core shaft's overcoat, lock core shaft and the thumb wheel of unblanking, lock core shaft is socketed in lock core shaft's outer casing internal diameter and is rotatably assorted to fixing and formation, offer elongated slot in lock core shaft, install stop pin in the elongated slot, stop pin matches with pellet shot from a slingshot in the lock core shaft, and the front end of stop pin has extension; In the thumb wheel of unblanking, have two driving members that are oppositely arranged, driving member slip socket is spacing on the connecting axle of overcoat top spring, the two ends roof pressure of top spring is on two driving members of both sides, the two ends of connecting axle enter the key hole of both sides lock core shaft, and driving member matches with the extension of stop pin front end; Periphery in lock core shaft is offered annular groove, and top sliding block axially is set on the annular groove, and a side of top sliding block arranges stage clip, and opposite side matches with stop pin.
A side of key hole arranges the key positioner steel ball in lock core shaft, and a side of key positioner steel ball is provided with elastic component.
The lock core shaft of key hole axis sidepiece arranges the pellet shot from a slingshot blind hole in lock core shaft, one side of pellet shot from a slingshot blind hole is communicated with key hole, assembling spring and pellet shot from a slingshot in the pellet shot from a slingshot blind hole, one side of pellet shot from a slingshot forms projection and gives prominence in key hole, the opposite side of pellet shot from a slingshot arranges the sliding groove that pushes away, sliding push away that the stop pin in the elongated slot matches in groove and the relative lock core shaft, the opposite face of stop pin and pellet shot from a slingshot is provided with lock slots.
The present invention is by above-mentioned specific design, the close tooth of key do not match or lock core when impacted by violence to rotate lock core only be in idling conditions, improved the theftproof performance of lock core greatly, have and anti-ly dial that performance is strong, fault rate is low, the advantage of good reliability.
