Description
Technical field
The present invention relates to a kind of lockset, particularly a kind of tapered end with arced marble.
Background technology
What existing lockset was general all is the lock core of double-deck billiards structure.Its operating principle is: the active force by spring is shifted double-deck pellet shot from a slingshot between lock core and the lock housing onto, and fixed lock core can not rotate freely.When key inserts, the pellet shot from a slingshot of first floor varying length is shifted onto the lock core justified margin, just can free rotational lock core.Such device in the master key fine rotation, is dialled and is pressed pellet shot from a slingshot, makes each pellet shot from a slingshot all reach the position at lock core edge, also can open.Same atom is when main pellet shot from a slingshot is pressed onto the relevant position simultaneously, rotary locking cylinder, and secondary pellet shot from a slingshot just may be withdrawn in the core.Because secondary pellet shot from a slingshot is corresponding main pellet shot from a slingshot, separately work also can be opened with top method.When the lock core that has an intelligence ring was used unlocked by universal key, self-locking device can be automatically locked, and promptly uses first wife's key also not open, and lockset has just been scrapped like this.Also having a kind of lock core made from the coded lock operating principle, is to form with several reeds.When the breach of each reed being turned to corresponding overcoat breach, slide bar slips into cell body, just can rotational lock core, but such device but can not be unblanked in reverse rotation.
Summary of the invention
The objective of the invention is to overcome the prior art defective, a kind of tapered end that can effectively prevent the band arced marble of unlocked by universal key is provided.
In order to realize above purpose, the present invention is by the following technical solutions: a kind of tapered end with arced marble, include lock housing and lock core assembly, it is characterized in that: described lock core assembly includes slide bar, columnar lock tube, columniform plug body, a plurality of arced marbles, lock housing is provided with lock core assembly containing cavity, lock tube is located in the lock housing rotationally, lock tube is set on the plug body, plug body is provided with many cannelures that the edge is circumferential, the same circumferential position of cannelure sidewall place is provided with breach I, the gap that forms between breach I and the lock tube has constituted key insertion hole, arced marble can circumferentially be located in the cannelure rotationally, the arcwall face in the outside of arced marble flushes with the arc upper edge face of cannelure, described lock tube is provided with the slide bar containing cavity vertically, slide bar places in the slide bar containing cavity, the lock housing position relative with slide bar is provided with cell body, the cannelure sidewall same circumferential position place relative with slide bar is provided with breach II, all be provided with the breach of unblanking on each arced marble, one end of arced marble is towards key insertion hole, the other end is connected with back-moving spring, and this back-moving spring makes arced marble produce a trend that stretches into key insertion hole.
Beneficial effect of the present invention is: the present invention is provided with a plurality of arced marbles, be provided with slide bar at lock tube, as long as there is the breach of unblanking of an arced marble not aim at slide bar, slide bar just is stuck in the lock housing cell body, lock housing just can not be rotated relative to plug body, also just can't unblank.Compare existing tapered end, can prevent effectively that stealer from using the dial-up mode to unblank.
Below in conjunction with accompanying drawing the present invention is described in further detail

The specific embodiment
To shown in Figure 5, a kind of tapered end with arced marble includes lock housing 2 and lock core assembly as Fig. 1.The lock core assembly includes slide bar 1, columnar lock tube 5, columniform plug body 4, a plurality of arced marble.Lock housing 2 is a cylindrical shell, and the external diameter of lock tube 5 is consistent with lock housing 2 center cavity internal diameters, lock tube 5 rotating being located in lock housing 2 cavitys.Lock tube 5 is set on the plug body 4.Plug body 4 is provided with many cannelures 43 that the edge is circumferential, be provided with two arced marbles 3 in every cannelure 43, arced marble 3 can circumferentially be located in the cannelure 43 rotationally, the same circumferential position of each cannelure 43 sidewall place is provided with breach I 41, and the gap that forms between breach I 41 and the lock tube 5 has constituted key insertion hole.An end that is in two arced marbles 3 in the same cannelure 43 links to each other by a back-moving spring 6, and the other end of two arced marbles 3 stretches in the key insertion hole.Back-moving spring 6 makes arced marble 3 produce a trend that stretches into key insertion hole.The circumferential lengths of arced marble 3 has nothing in common with each other, and the length that therefore stretches into key insertion hole also has nothing in common with each other.The arcwall face in the outside of arced marble 3 flushes with the arc upper edge face of cannelure 43.Lock tube 5 is provided with two slide bar containing cavities vertically symmetrically, respectively is provided with a slide bar 1 in each slide bar containing cavity, and slide bar 1 is a cylinder.Lock housing 2 and slide bar 1 relative position is provided with cell body 21, and the cannelure 43 sidewalls same circumferential position place relative with slide bar 1 is provided with breach II 42, all is provided with the breach 31 of unblanking on each arced marble 3 in the deep-slotted chip breaker.
Operating principle of the present invention is as follows: when key does not insert tapered end, arced marble 3 in the cannelure 43 is under the elastic force effect of back-moving spring 6, the one end stretches in the key insertion hole, breach II 42 on unblank breach 31 and the lock housing 2 on the arced marble 3 staggers, as long as there is this moment a breach 31 of unblanking not align with breach II 42 on the lock housing 2, slide bar 1 just is stuck in lock housing 2 cell bodies 21 by the arcwall face in arced marble 3 outsides.Because the inhibition of slide bar 1 is arranged, both can not relatively rotate between this moment lock housing 2 and the lock tube 5, and lock tube 5 links to each other with driving member, and lock tube 5 can not rotate, and driving member also just can't rotate, and tapered end also just can't be opened.When key inserts, the key bit of key both sides promotes the arced marble 3 in the cannelure 43 to both sides, the breach 31 of unblanking of each arced marble 3 all forwards the 42 same circumferential position places with lock housing 2 breach II to, rotate lock tube 5 this moment, slide bar 1 slips into the neutral gear position place that arced marble 3 is unblanked breach 31 and lock housing 2 breach II 42 formation under cell body 21 hypotenuse repulsions, the inhibition that lock tube 5 and lock housing 2 have not had slide bar 1 just can freely rotate, and tapered end just can be opened.
The present invention is arranged on two arced marbles 3 is set in each cannelure 43, and correspondingly lock housing 2 is provided with two cell bodies 21, and lock tube 5 is provided with two slide bars 1.Even there is the people to use master key to unblank like this, because arced marble 3 is two-sided stressed, when pushing one side arced marble 3, another arced marble 3 also can be stressed, and dial-up the sensation that is difficult to find corresponding yardage like this.An arced marble 3 can certainly only be set in cannelure 43, and correspondingly establishing a cell body 21 on the lock housing 2 also is a kind of embodiment.
The present invention is provided with a reference column 51 vertically in lock tube 5 key insertion hole positions, and this reference column 51 is suitable with strip groove on the key, after key inserts key insertion hole like this, just can drive lock tube 5 and circumferentially rotate.This reference column 51 also can make the arced marble 3 in the cannelure can arbitrarily not rotate simultaneously.Reference column 51 can drive plug body and rotate, and also can strengthen the modulus of key.
