Abstract
The utility model discloses a novel idle-running lock core which mainly solves the problems of the existing lock core that a tool can be very easily inserted into a key hole to forcibly twist the lock core so as to open a lock. The novel idle-running lock core is characterized in that a rear lock core is arranged between a front lock core and a thumbwheel; the rear lock core is matched with the shift wheel in a linkage manner; a clamping groove is formed in each blade; a clutch groove is formed in the front lock core; a clamping strip fitted with the clamping grooves is arranged in the clutch groove; a clutch strip is clung to the upper surface of the clamping strip, and is matched with the rear lock core in a linkage manner; the clamping strip is provided with a first position parallel and level to the outer surface of the front lock core and a second position lower than the outer surface of the front lock core. The novel idle-running lock core has the advantages that the structure of the lock core is optimized; when a tool is used for unlocking, the clamping strip is not enabled to fall into the clamping grooves by the tool, and when the tool is rotated, the front lock core is enabled to only perform idle running, and the lock cannot be opened, so that the anti-theft performance and the stability of the mechanism are improved.
Description
Technical field
The utility model relates to a kind of lock core, is specifically related to a kind of Novel air rotation cores.
Background technology
General lock core is when common state, and the blade of the inside all keeps coordinating with core body, and blade can not dally, and insertion key can twist core body and unblank.Such lock core is easy to be waited in instrument insertion keyhole and twist by force blade and then drive core body to unblank by omnipotent spoon, and theftproof performance is poor.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of Novel air rotation cores, has mainly solved existing lock core and has been easy to be inserted by instrument the problem that twists by force lock core and then unblank in keyhole.
The technical scheme that the utility model adopts is: a kind of Novel air rotation cores, comprise housing, thumb wheel, in described housing, be provided with front lock core, in described front lock core, be provided with some blades, between described front lock core and thumb wheel, be provided with rear lock core, described rear lock core and thumb wheel are linked, described blade is provided with draw-in groove, described front lock core is provided with clutch slot, in described clutch slot, be provided with the card article suitable with draw-in groove, described card article upper surface is fitted with clutch bar, described clutch bar and rear lock core are linked, described card article has the primary importance concordant with front lock core external surface and lower than the second place of front lock core external surface.
In described housing, be provided with the standing groove vertical with clutch slot, be provided with successively clutch upper prop, spring, clutch lower prop in described standing groove, described clutch lower prop and clutch bar are inconsistent.
Between described rear lock core and thumb wheel, be provided with contiguous block, described contiguous block both sides are extended with driving fixture block, and described lock core and thumb wheel are provided with and the groove that drives fixture block adaptation.
Described clutch bar is L-type, and described rear lock core is provided with the link slot with L-type lower end adaptation.
The beneficial effects of the utility model are: optimized lock core structure, when unblanking with instrument, instrument cannot make card article fall into draw-in groove, and turning tool can only make front Lock cylinder idling, as long as broken with unlocking tool, makes lock core rotate the law that just can unblank, not only can be anti-drilling but also can pick-proof, when thief inserts lock core special-purpose destructive instrument, due to Lock cylinder idling, cannot find origin of force, in the time of technical opening, be also difficult to put forth effort, cannot unblank, improve theftproof performance and the stability of mechanism.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of blade 4.
1-housing in figure, 1001-standing groove, 2-thumb wheel, lock core before 3-, 4-blade, 41-draw-in groove, 5-rear lock core, 51-link slot, 6-clutch slot, 7-card article, 8-clutch bar, 9-clutch upper prop, 10-spring, 11-clutch lower prop, 12-contiguous block, 121-drives fixture block, 13-groove.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 with Figure 2, a kind of Novel air rotation cores, comprise housing 1, thumb wheel 2, in described housing 1, be provided with front lock core 3, in described front lock core 3, be provided with some blades 4, between described front lock core 3 and thumb wheel 2, be provided with rear lock core 5, described rear lock core 5 is linked with thumb wheel 2, described blade 4 is provided with draw-in groove 41, described front lock core 3 is provided with clutch slot 6, in described clutch slot 6, be provided with the card article 7 suitable with draw-in groove 41, described card article 7 upper surfaces are fitted with clutch bar 8, described clutch bar 8 is linked with rear lock core 5, described card article 7 has the primary importance concordant with front lock core 3 external surfaces and lower than the second place of front lock core 3 external surfaces.
In described housing 1, be provided with the standing groove vertical with clutch slot 6 1001, be provided with successively clutch upper prop 9, spring 10, clutch lower prop 11 in described standing groove 1001, described clutch lower prop 11 is inconsistent with clutch bar 8.
Between described rear lock core 5 and thumb wheel 2, be provided with contiguous block 12, described contiguous block 12 both sides are extended with and drive fixture block 121, and described rear lock core 5 is provided with and the groove 13 that drives fixture block 121 adaptations with thumb wheel 2.
Described clutch bar 8 is L-type, and described rear lock core 5 is provided with the link slot 51 with L-type lower end adaptation.
The concrete use of the utility model is as follows: when picking lock, cannot make the draw-in groove 41 on each blade 4 be aligned to straight line, card article 7, clutch bar 8 can not fall, and front lock core 3 can only dally, and it rotates and can not drive clutch bar 8 and then drive rear lock core 5 to rotate together; When inserting first wife's key, draw-in groove 41 on blade 4 is aligned to straight line, and card article 7 falls into the draw-in groove 41 of alignment, and clutch bar 8 declines and falls into clutch slot 6, before rotating, lock core 3 can drive rear lock core 5, contiguous block 12, thumb wheel 2 to rotate together successively, thereby reaches unlocking function.
The beneficial effect of utility model is: optimized lock core structure, when unblanking with instrument, instrument cannot make card article fall into draw-in groove, and turning tool can only make front Lock cylinder idling, as long as broken with unlocking tool, makes lock core rotate the law that just can unblank, not only can be anti-drilling but also can pick-proof, when thief inserts lock core special-purpose destructive instrument, due to Lock cylinder idling, cannot find origin of force, in the time of technical opening, be also difficult to put forth effort, cannot unblank, improve theftproof performance and the stability of mechanism.
