Description
Technical field
The utility model belongs to mechanical lock, relates to the lock of the inside and outside mill teeth lamina idle-run of a kind of improved employing lock core.
Background technology
Have class lock to adopt idle-run lock pin in the mechanical lock, the lock core of these locks is made up of forward and backward lock core, will realize clutch between them by clutch structure usually between preceding lock core and the rear lock core.Chinese patent application 200710035819.1,200810031951.X disclose the clutch structure of relevant idle-run lock pin.Comprise the lock pin and the lock pin back-moving spring that are located in the rear lock core in these clutch structures, lock core was realized before the clutch of front and back lock core entered or withdraws from by lock pin.This clutch structure is in use found some shortcomings, owing to frequently unblank to shut for a long time, the lock pin back-moving spring can produce metal fatigue, elasticity weakens, and adds the abrasive dust of component and the dirt that dust forms, and its elasticity further weakens, so that when unblanking lock pin is resetted, lock always is in idling conditions, lock can't be opened the reliability of influence lock.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of lock of the inside and outside mill teeth lamina idle-run of improved employing lock core of better reliability is provided.
Realize that the technical scheme that the utility model purpose adopts is: the lock of the inside and outside mill teeth lamina idle-run of improved employing lock core comprises lock body, is located at preceding lock core and rear lock core in the lock body; Before lock core upper edge axis to be provided with some be one group blade marble group by two blade marbles, the same side of blade marble in the blade marble group, wherein the end of the middle part of a blade marble and another blade marble is respectively equipped with the projection that extend in the keyhole, the opposite side of each blade marble is provided with breach, and corresponding each blade marble is provided with the blade marble return spring respectively on the preceding lock core; Before be provided with in the locking side column groove on the lock core match with blade marble can axially-movable locking side column, locking side column is provided with the tooth mouth and cooperates with blade marble, the breach on the blade marble cooperates with locking side column; On preceding lock core, be with sleeve, between the end wall of locking side column and locking side column groove, be provided with the axial back-moving spring of locking side column; Be placed with lock pin in the lock pin chute of rear lock core, the lock body afterbody is provided with the step with the rear lock core stop bit; Described sleeve is fixed on the preceding lock core and is enclosed within on the rear lock core, and sleeve and rear lock core matched in clearance are provided with the elasticity positioning bead between sleeve and rear lock core; The afterbody of described lock pin is taper; Described lock body afterbody step is provided with the cone tank that matches with the lock pin afterbody.
The utility model matches with the interior mill teeth and the outer mill teeth of key because of its blade marble, so be called the lock of the inside and outside mill teeth lamina idle-run of improved employing lock core.
The utility model changes the lock pin afterbody in the prior art rear lock core into taper and matches with cone tank on the lock body afterbody step, cancelled the lock pin back-moving spring, therefore can solve fully because of the lock pin back-moving spring follows the string and cause locking the problem that normally to use, improve the reliability of lock, increase the service life.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.

The specific embodiment
See Fig. 1 to Fig. 3, in the improved employing, the lock of outer mill teeth lamina idle-run lock core, comprise lock body 2, preceding lock core 1 and rear lock core 11 in the lock body 2, preceding lock core 1 upper edge axis is provided with some by two blade marbles 7,17 is one group blade marble group, blade marble 7 in the blade marble group, the same side of 17, wherein the end of the middle part of a blade marble 7 and another blade marble 17 is respectively equipped with the projection 16 that extend in the keyhole, 19, each blade marble 7,17 opposite side is provided with breach 20, corresponding each blade marble 7 on the preceding lock core 1,17 are provided with blade marble return spring 21 respectively; Before be provided with in the locking side column groove on the lock core 1 match with blade marble 7,17 can axially-movable locking side column 5, locking side column 5 is provided with tooth mouth 6 and cooperates with blade marble 7,17, the breach 20 on the blade marble 7,17 cooperates with locking side column 5; On forward and backward lock core, be with sleeve 3, between the end wall of locking side column 5 and locking side column groove, be provided with the axial back-moving spring 4 of locking side column; Place lock pin 8 in the lock pin chute 10 of rear lock core 11, the afterbody 24 of lock pin 8 is taper; The lock body afterbody is provided with the step 13 with rear lock core 11 stop bits, and this step 13 is provided with the cone tank 9 that matches with lock pin afterbody 24; On the lock core 1, sleeve 3 and rear lock core 11 matched in clearance were provided with the elasticity positioning bead of being made up of steel ball 14 and spring 15 on rear lock core 11, be provided with the hole and match with steel ball 14 on sleeve 3 before sleeve 3 was fixed on; Rear lock core 11 is provided with sword iron 12.
Operating principle of the present utility model: see Fig. 1 to Fig. 3 when unblanking, insert key 18, on the key 18 band pellet shot from a slingshot cell wall (interior mill teeth) 23 of tartar and boss (outer mill teeth) 22 respectively with blade marble 7, protuberance 16 on 17,19 cooperate, make the blade marble 7 of the tooth mouth 6 that is positioned at locking side column 5,17 to left movement (referring to Fig. 2), breach 20 alignment of their sides are in the state that cooperates with locking side column 5, locking side column 5 can axially-movable, lock core 1 before rotating in the direction of arrows again, driving rear lock core by the sleeve on the lock core 1 before being fixed on 3 rotates with respect to lock body 2, the tapered tail 24 of ramp effect lock pin 8 in rear lock core of the cone tank 9 on the step 13 of lock body afterbody, the elastic force that forces lock pin 8 to overcome the axial back-moving spring 4 of locking side column enters in the locking side column groove of preceding lock core 1, before inciting somebody to action, rear lock core fuses, and realizes unblanking; See Fig. 4, Fig. 5 when locking, rotate forward and backward lock core by arrow, when the lock pin in the rear lock core 8 when cone tank on the lock body afterbody step aligns, locking side column under its axial action of reset spring, lock pin 8 pushed up back in the rear lock core with lock body afterbody step on cone tank coincide, forward and backward lock core separates, and extracts key 18 out, locking side column 5 returns, breach dislocation on the blade marble, blade marble is realized locking side column 5 stop bits to lock.
If unblank with non-matching key or instrument, locking side column 5 not can with blade marble 7, breach 20 on 17 cooperates, at blade marble 7, can't axially-movable under 17 the stop bit, even if rear lock core 11 rotates with respect to lock body 2, under locking side column 5 stops, lock core 1 before cone tank 9 on the lock body afterbody step 13 also can't force lock pin 8 to enter, if lock core 1 before still rotating in this case, because the sleeve 3 before being fixed on the lock core 1 adopts the elasticity positioning bead to be connected with rear lock core 11, in case rotate torsion greater than the resistance of elasticity positioning bead to sleeve 3, preceding lock core 1 will be done idle running by relative together rear lock core 11 with sleeve 3, can't unblank.
