Abstract
The invention discloses a lock adopting idle lock cylinders with double-row pin tumblers, comprising a front lock cylinder and a rear lock cylinder, which are arranged in a lock body. The front lock cylinder is provided with double-row pin tumblers with V-shaped grooves symmetrically along the axis. Locking side columns which can match the V-shaped grooves on the pin tumblers and move axially are respectively arranged in locking side column grooves symmetrically arranged on the front lock cylinder. The rear lock cylinder is provided with a lock pin. A step for stopping the rear lock cylinder is arranged at the tail of the lock body. A sleeve is fixed on the front lock cylinder and is sleeved on the rear lock cylinder. The sleeve is in clearance fit with the rear lock cylinder. An elastic ball plunger is arranged between the sleeve and the rear lock cylinder. The tail of the lock pin is cone-shaped and a cone-shaped groove matched with the tail of the lock pin is arranged on the step at the tail of the lock body. The lock removes the lock pin return spring in the prior art, thus being capable of completely solving the problem that the lock can not be used normally because the lock pin return spring loses elasticity, enhancing the lock reliability and prolonging the service life.
Description
Technical field
The invention belongs to mechanical lock, relate to a kind of lock that adopts double billiard idle lock cylinder.
Background technology
Have one type of 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 the clutch between them through clutch structure usually between preceding lock core and the rear lock core.One Chinese patent application 200810030910.9 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 got into or withdraws from through lock pin.This clutch structure is in use found some shortcomings, owing to frequently unblank for a long time to close lock, 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, can't lock be opened the reliability of influence lock.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of lock of the double billiard idle lock cylinder of employing of better reliability is provided.
Realize that the technical scheme that the object of the invention adopts is: adopt the lock of double billiard idle lock cylinder, comprise lock body, be located at preceding lock core and rear lock core in the lock body; Preceding lock core upper edge axis is arranged with the double pellet shot from a slingshot of band v-depression; Before be respectively equipped with in the symmetrically arranged locking side column groove on the lock core can match with v-depression on the pellet shot from a slingshot can axially-movable locking side column; Each locking side column is provided with step-like groove, and 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 on the rear lock core with in the lock pin chute of the corresponding setting of each locking side column groove, the lock body afterbody is provided with the step with the rear lock core stop bit; Said 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 said lock pin is taper; Said lock body afterbody step is provided with the cone tank that matches with the lock pin afterbody.
The present invention 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 scheme of the present invention below in conjunction with accompanying drawing.

The specific embodiment
See Fig. 1 to Fig. 3, adopt the lock of double billiard idle lock cylinder, comprise preceding lock core 1 and rear lock core 11 in lock body 2, the lock body 2; Preceding lock core 1 upper edge axis is arranged with the double pellet shot from a slingshot 14 of band v-depression 15; Before be respectively equipped with in the symmetrically arranged locking side column groove on the lock core 1 can match with the v-depression 15 on the pellet shot from a slingshot 14 can axially-movable locking side column 6; Each 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; On rear lock core 11 with in the lock pin chute 17 of the corresponding setting of each locking side column groove, place lock pin 9, the afterbody 20 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 20; 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 18 and spring 19 on rear lock core 11, on sleeve 3, be provided with the hole and match with steel ball 18 before sleeve 3 was fixed on; Rear lock core 11 is provided with sword iron 12.
Operating principle of the present invention: see Fig. 1 to Fig. 3 when unblanking, insert key 16, each arranges v-depression 15 alignment on the pellet shot from a slingshot 14; Locking side column 6 is inwardly motion radially, makes card 8 be positioned at the topping bar of step-like groove 7 of locking side column 6, and locking side column 6 can axially-movable; Press arrow again and rotate preceding lock core 1; Drive rear lock core through the sleeve on the lock core 1 before being fixed on 3 and rotate with respect to lock body 2, the tapered tail 20 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 gets in the locking side column groove of preceding lock core 1; Forward and backward lock core is fused, realize 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 with lock pin 9 push up back in the rear lock core with lock body afterbody step on cone tank coincide; Forward and backward lock core separates; Extract key 16 out, locking side column 6 returns are realized locking.If unblank with non-matching key or instrument, locking side column 6 can not cooperate with pellet shot from a slingshot 14 does radially inwardly motion, 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 stoped, if lock core 1 before the cone tank 10 on the lock body afterbody step 13 also can't force lock pin 9 to get into was 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 with sleeve 3 relative rear lock cores 11, can't unblank.
