Description

The lock of mill teeth lamina idle-run lock core in a kind of the employing
Technical field
The utility model belongs to mechanical lock, relates to the lock of mill teeth lamina idle-run lock core in a kind of the employing.
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 200810031195.0 discloses a kind of clutch structure of idle-run lock pin.Comprise the lock pin and the lock pin back-moving spring that are located in the rear lock core in this clutch structure, 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 interior mill teeth lamina idle-run lock core of employing of better reliability is provided.
Realize that the technical scheme that the utility model purpose adopts is: the lock of mill teeth lamina idle-run lock core in adopting comprises lock body, is located at preceding lock core and rear lock core in the lock body; Before lock core upper edge axis be provided with some to be one group blade marble group by two blade marbles, to be provided with the blade marble back-moving spring between two blade marbles; One side of each blade marble is provided with v-depression, and the centre is provided with rectangular lockhole, be provided with at the middle part, long limit of lockhole can with the protuberance that matches with the pellet shot from a slingshot cell wall of tartar on the key; Before be provided with in the locking side column groove on the lock core can match with v-depression on the blade marble can axially-movable locking side column; Locking side column is provided with step-like groove, the top of locking side column groove is provided with and the locking side column card that the scalariform groove matches of appearing on the stage, on preceding lock core, be with sleeve, between sleeve and locking side column, be provided with radially back-moving spring of locking side column, 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 interior mill teeth key because of its blade marble, so be called the lock that adopts interior mill teeth lamina idle-run 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, the lock of mill teeth lamina idle-run lock core in adopting, comprise preceding lock core 1 and rear lock core 11 in the lock body 2, lock body 2, it is one group blade marble group by two blade marbles 16 that preceding lock core 1 upper edge axis is provided with some, is provided with blade marble back-moving spring 17 between two blade marbles 16; One side of each blade marble 16 is provided with v-depression 21, and the centre is provided with rectangular lockhole 20, be provided with at the middle part, long limit of lockhole 20 can with pellet shot from a slingshot cell wall (interior mill teeth) 22 protuberances that match 23 of band tartar on the key 19; Before be provided with in the locking side column groove on the lock core 1 can match with v-depression 21 on the blade marble 16 can axially-movable locking side column 6, locking side column 6 is provided with step-like groove 7, the top of locking side column groove is provided with and the locking side column card 8 that scalariform groove 7 matches of appearing on the stage, on forward and backward lock core, be with sleeve 3, between sleeve 3 and locking side column 6, be provided with radially back-moving spring 5 of locking side column, between the end wall of locking side column 6 and locking side column groove, be provided with the axial back-moving spring 4 of locking side column; Place lock pin 9 in the lock pin chute 18 of rear lock core 11, the afterbody 24 of lock pin 9 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 10 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 19, protuberance 23 on the key 19 on the lockhole 20 of pellet shot from a slingshot cell wall (interior mill teeth) 22 and the blade marble 16 of band tartar cooperates, make v-depression 21 alignment of each blade marble 16 1 side, locking side column 6 radially moves downward, make card 8 be positioned at the topping bar of step-like groove 7 of locking side column 6, locking side column 6 can axially-movable, press arrow again and rotate preceding lock core 1, 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 9 in rear lock core of the cone tank 10 on the step 13 of lock body afterbody, the elastic force that forces lock pin 9 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 9 when cone tank on the lock body afterbody step aligns, locking side column under its axial action of reset spring, lock pin 9 pushed up back in the rear lock core with lock body afterbody step on cone tank coincide, forward and backward lock core separates, extract key 19 out, locking side column 6 returns are realized locking.If unblank with non-matching key or instrument, locking side column 6 can not cooperate to do radially and moves downward with blade marble 16, can't axially-movable under the stop bit of card 8, even if rear lock core 11 rotates with respect to lock body 2, under locking side column 6 stops, lock core 1 before cone tank 10 on the lock body afterbody step 13 also can't force lock pin 9 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.
