Referring to accompanying drawing 1.On active lock core 2, offer several through slots that is arranged in parallel 23; Per two conversion shell fragments 22 are arranged in the through slot alternately; A side of the interactive key of contiguous shell fragment offers the V-type groove on the interactive sheet of every shell fragment, and relative opposite side is provided with the teeth corresponding with this lock key.Initiatively lock core 2 is offered keyway 6 on the direction that is parallel to the lock core axis, and the interactive key 5 of shell fragment is arranged in keyway 6.The interactive key 5 of steady key 4 next-door neighbour's shell fragments leads.
After this lock key 14 inserted, teeth extruding conversion shell fragment 22 on the key made the V-type groove on it be arranged in straight line, and the interactive key 5 of shell fragment falls into this V-type groove; At this moment; The steady key that leads breaks away from the hole groove 8 that is positioned at outer casing inner wall by 4 under the effect of back-moving spring, get into the keyway 6 that is arranged on the active lock core, and the steady key 4 that leads links together with active lock core 2 with by movable lock core 3; Form expendable locked structure; Because initiatively an end of lock core 2 inserts by an end of movable lock core 3 hollows and forms nested structure, is provided with locking member 7 in this part nested structure, after forming expendable locked structure; Be rotated further key, locking member 7 is connected to form the secondary latch-up structure with the active lock core with by movable lock core 3.
In the prior art; Theftproof lock is latch-up structure for once; The steady key 5 that leads bears all torsion torque and the shearing force that the process of unblanking produces, and easy deformation and damage are very difficult as if the intensity and the theftproof performance that improve theftproof lock through the volume that increases the steady key 4 of guiding; Because the volume of lock core is very little, the volume of the steady key 4 that leads is difficult to increase.The present invention is the theftproof lock with secondary latch-up structure, and moment of torsion when unblanking and shearing force effect act on two kinds of various parts in order, has improved the intensity and the theftproof performance of theftproof lock greatly.
Accompanying drawing of the present invention discloses the secondary latch-up structure of two kinds of forms.
Accompanying drawing 1～accompanying drawing 5 is anti-theft lock ends of the secondary latch-up structure of first kind of form of the present invention.In the theftproof lock of the secondary latch-up structure of first kind of form; Is hollow circular cylinder by movable lock core 3 near an end of active lock core 2; In preferred version; Initiatively lock core 2 is near being small column by an end of movable lock core, and this small cylinder is mutually nested with this cylinder by movable lock core hollow, forms nested connecting portion.On by the cylinder body of movable lock core hollow, offer, promptly be positioned at the keyway 11 on the passive lock core perpendicular to lock core axis through hole; On the small cylinder of active lock core 2, offer perpendicular to the lock core axis and the keyway 10 that can let locking member 7 insert smoothly and extract; Place in the keyway 10 and be used for the spring 18 peaceful pearls 19 that locking member 7 resets; Be provided with groove 9 with locking member 7 corresponding positions on the outer casing inner wall; One end of locking member 7 has projection 12.When locking, the projection 12 on the locking member 7 is arranged in the groove 9 on the outer casing inner wall, locking member 7 be positioned at initiatively lock core 2 with the said projection 12 relative other ends and by the boundary of movable lock core 3.After this lock key 14 inserted, the steady key 3 that leads broke away from and is positioned at the groove 8 on the outer casing inner wall, and fell into the keyway 6 that is positioned on the lock core initiatively, and initiatively lock core 2 be connected by movable lock core 3, form expendable locked structure; Form continued key 14 in expendable locked structure; Initiatively lock core 2 will drive by movable lock core 3 and rotate; At this moment; Prominent sharp 12 of locking member 7 is being done to skid off described groove 9 when circumferentially rotating by movable lock core 3, make locking member 7 insert the keyway 10 that is arranged on the lock core initiatively away from the other end of prominent point 12 under the extruding of wall in the enclosure of prominent point 12, thereby form the secondary latch-up structure.Under expendable locked structure and the simultaneous situation of secondary latch-up structure,, realized the unlatching of theftproof lock by movable lock core by active lock core 2 driven rotary.In the above-described embodiments, the preferred polygon of the cross sectional shape of locking member 7, the shape of keyway 10 and keyway 11 is also selected polygon accordingly, and for example, rectangle also can be selected circle.
Remove this; The Another reason that locking member 7 improves theftproof performances is: if theftproof lock latch-up structure once only, when theftproof lock by the people use electric drill from a side of active lock core 2 along the boring of lock core axis direction, in drill bit inserts by movable lock core 3; At this moment drill bit links together with the active lock core with by movable lock core; Lock core 2 rotates if tool using or master key drive initiatively, is then followed active lock core 2 by movable lock core 3 and rotates together, and theftproof lock is opened by illegal; And that theftproof lock of the present invention meets with is above-mentioned when illegally unblanking by electric drill; The vibration of electric drill misplaces locking member 7 and the keyway 10 that is positioned on the active lock core 2; The bottom of locking member will be stuck in the inlet of keyway 10 after initiatively lock core 2 rotates; Its projection 12 is stuck in the groove 9, and locking member 7 can not be inserted in the keyway 10, and theftproof lock stops illegal unlatching because of being stuck.When the cross section of locking member 7 is a polygon, meet when illegally unblanking with electric drill, locking member 7 and keyway 10 more difficult centerings, locking member 7 more difficulty falls into keyway 12, and the theftproof performance of theftproof lock is stronger.
Accompanying drawing 6-8 is the anti-theft lock end of the secondary latch-up structure of second kind of form of the present invention.The theftproof lock of the secondary latch-up structure of second kind of form is with the theftproof lock main difference part of the secondary latch-up structure of first kind of form: the former locking member 7 with the direction of lock core shaft line parallel with formed secondaries by movable lock core 3 and be connected; The latter's locking member 7 then with the direction of axis normal on lock core 2 and be connected to form the secondary locking initiatively by movable lock core 3.
The concrete structure of the secondary latch-up structure theftproof lock of second kind of form with the principle of unblanking is: locking member 7 is made up of spheroid 71 and contiguous block 72; Initiatively the keyway 10 on the lock core is parallel to the lock core axis; Contiguous block 72 is the bottom of locking member away from an end of spheroid 71, and the position that outer casing inner wall is corresponding with spheroid is provided with groove groove 9.During locking, the spheroid 71 in the locking member 7, its part is arranged in the groove 8 of outer casing inner wall, forms the top of locking member 7; When unblanking, steady key 3 disengagings of leading are positioned at the groove 8 on the outer casing inner wall, fall into the keyway 6 that is arranged on the active lock core, link together with active lock core 2 with by movable lock core 3, form expendable locked structure.After forming expendable locked structure; Be rotated further key 14; Spheroid 71 skids off groove 9 and receives the extruding of outer casing inner wall, and contiguous block 72 is inserting the keyway 10 that is arranged on the active lock core and is parallel to the lock core axis away from an end of spheroid under the extruding of spheroid 71, and clamping block 72 is joined together to form the secondary latch-up structure with active lock core 2 with by movable lock core 3; Theftproof lock is opened by this lock key under expendable locked structure and the simultaneous situation of secondary latch-up structure.
In order to improve the intensity of theftproof lock; The theftproof lock of above-mentioned two kinds of secondary latch-up structure forms; Can select to adopt following technical scheme (a key many places locking scheme): initiatively lock core 2 is provided with shrinkage pool 15 at described nested connecting portion, and the steady key 4 that leads is shaped as 7 fonts or approximate T type, during locking; Steady key 4 its long limits of leading are arranged in the groove 8 on the outer casing inner wall, and its minor face is arranged in by the link slot on the movable lock core 24; When unblanking, the long limit of the steady key 4 that leads breaks away from described groove 8 and falls into the keyway 6 on the active lock core, and its minor face inserts in the described shrinkage pool 15 through described link slot 24, realizes the locking of a key (steady key promptly leads) many places.When use is similar to the steady key of guiding of T type, can back-moving spring (referring to Fig. 1) be set on the steady key minor face of guiding side, make steady key 4 actions of guiding more steady.
For further improving theftproof performance; Can select to adopt following preferred scheme: in nested connecting portion; Initiatively plug face has pit or protruding 16; Bottom at steady key 4 minor faces of guiding is provided with convexity or pit 17, and in nested connecting portion, initiatively the surface of lock core can be meshing with each other with the bottom of the steady key 4 of guiding.The advantage of this structure is: when this lock key inserted, the minor face horizontal stroke of the steady key that leads can insert in the shrinkage pool 15 smoothly, realizes unblanking; And when using master key to unblank, initiatively lock core pit or convex surfaces are meshing with each other with steady key 4 minor faces of guiding, and initiatively lock core is stuck, thereby prevent the active lock core to be rotated further and realize the secondary latch-up structure by error and tapered end is opened.
In the tradition theftproof lock; Often adopt flat pearl and the reposition element of spring (perhaps adopting spring separately) as the steady key 4 of guiding, therefore need in the enclosure on the wall boring so that place flat pearl and spring, this makes the manufacturing procedure complicacy of lock body shell; And assembly operation difficulty; For this reason, the present invention uses the stiffness spring sheet 13 with certain flexibility to be installed in traditional flat pearl and the spring of replacement in the groove 8 on the outer casing inner wall, has saved the operation of the other boring of wall in the enclosure; Easy to assembly quick, improved production efficiency.
In order to incite somebody to action active lock core 2 and to be connected by movable lock core and to locate; At active lock core and the nested connecting portion that is formed by movable lock core, offered the card hole 25 of perforation by movable lock core perpendicular to the lock core axis, offer the draw-in groove 26 of ring-type at the active lock core position corresponding with said draw-in groove; Card 27 inserts described card hole 25 and described draw-in groove 26; Like this, initiatively lock core with on the lock core axis direction, linked together and lock core and can be relatively rotated initiatively by movable lock core by movable lock core.
Obviously; The theftproof lock technical scheme of two kinds of forms of secondary latch-up structure of the present invention; No matter whether shrinkage pool 15 is set on the active lock core, no matter also whether intermeshing convexity and pit of connecting portion surface and the steady key of guiding bottom all is the embodiment and the protection domain of the invention.
