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 of process generation of unblanking, easy distortion and damage, if improve the intensity of theftproof lock by the volume increasing the steady key 4 of guiding and theftproof performance very difficult, 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 locking structure, and moment of torsion when unblanking and shearing force effect sequential action, on two kinds of different parts, substantially increase intensity and the theftproof performance of theftproof lock.
Accompanying drawing of the present invention discloses the secondary locking structure of two kinds of forms.
Accompanying drawing 1 ~ accompanying drawing 5 is anti-theft lock ends of the secondary locking structure of the first form of the present invention.In the theftproof lock of the secondary locking structure of the first form, be hollow circular cylinder by movable lock core 3 near one end of initiatively lock core 2, in a preferred approach, initiatively lock core 2 is close is small column by one end of movable lock core, this small cylinder is mutually nested by the cylinder of movable lock core hollow with this, forms nested encryptions portion.Offered perpendicular to lock core axis through hole by the cylinder body of movable lock core hollow, be namely positioned at the keyway 11 on passive lock core; The small cylinder of active lock core 2 is offered perpendicular to lock core axis and second keyway 10 that locking member 7 can be allowed to insert smoothly and extract; The peaceful pearl 19 of spring 18 being used for locking member 7 and resetting is placed in second keyway 10; Position corresponding with locking member 7 on outer casing inner wall is provided with groove 9; There is projection 12 one end of locking member 7.When locking, the projection 12 on locking member 7 is arranged in the groove 9 on outer casing inner wall, and the other end relative with described projection 12 of locking member 7 is positioned at initiatively lock core 2 and by the boundary of movable lock core 3.After this lock key 14 inserts, the steady key 3 that leads departs from the groove 8 be positioned on outer casing inner wall, and falls into the first keyway 6 be positioned on active lock core, and is connected with by movable lock core 3 by active lock core 2, forms expendable locked structure; Key 14 is rotated further after expendable locked structure is formed, initiatively drive is rotated by movable lock core 3 by lock core 2, at this moment, prominent sharp 12 of locking member 7 skids off described groove 9 when being done circumference rotation by movable lock core 3, make locking member 7 insert the second keyway 10 be arranged on initiatively lock core away from the prominent other end of sharp 12 under the extruding of prominent point 12 wall in the enclosure, thus form secondary locking structure.By movable lock core under expendable locked structure and the simultaneous situation of secondary locking structure, by active lock core 2 driven rotary, realize the unlatching of theftproof lock.In the above-described embodiments, the preferred polygon of cross sectional shape of locking member 7, the shape of the second keyway 10 and keyway 11 also selects polygon accordingly, and such as, rectangle, also can select circle.
Except this, the Another reason that locking member 7 improves theftproof performance is: if theftproof lock only once latch-up structure, when theftproof lock is used electric drill to hole from a side of active lock core 2 along lock core axis direction by people, until drill bit inserts by movable lock core 3, at this moment drill bit is by active lock core with linked together by movable lock core, if use instrument or master key drive initiatively lock core 2 to rotate, then followed initiatively lock core 2 by movable lock core 3 and rotate together, theftproof lock is illegally opened; And theftproof lock of the present invention meets with above-mentioned when illegally unblanking by electric drill, the vibration of electric drill makes locking member 7 and the second keyway 10 be positioned on active lock core 2 misplaces, the bottom that active lock core 2 rotates rear locking member will be stuck in the entrance of the second keyway 10, its projection 12 is stuck in groove 9, make locking member 7 can not insert in keyway 10, theftproof lock stops illegal unlatching because being stuck.When the cross section of locking member 7 is polygon, when chance electric drill is illegally unblanked, locking member 7 and the more difficult centering of keyway 10, locking member 7 is more difficult falls into keyway 10, and the theftproof performance of theftproof lock is stronger.
Accompanying drawing 6-8 is the anti-theft lock end of the secondary locking structure of the second form of the present invention.The theftproof lock of the secondary locking structure of the second form, is with the theftproof lock main difference part of the secondary locking structure of the first form: the former locking member 7 with the direction of lock core shaft line parallel with formed secondary by movable lock core 3 and be connected; The locking member 7 of the latter then with the direction of axes normal on be connected to form secondary locking by active lock core 2 with by movable lock core 3.
Concrete structure and the principle of unblanking of the secondary locking structure theftproof lock of the second form are: locking member 7 is made up of spheroid 71 and contiguous block 72, the second keyway 10 initiatively on lock core is parallel to lock core axis, contiguous block 72 is the bottom of locking member away from one end of spheroid 71, and the position that outer casing inner wall is corresponding with spheroid is provided with groove 9.During locking, the spheroid 71 in 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, the steady key 3 that leads departs from the groove 8 be positioned on outer casing inner wall, falls into the first keyway 6 be arranged on active lock core, links together, form expendable locked structure by active lock core 2 with by movable lock core 3.When after the expendable locked structure of formation, be rotated further key 14, spheroid 71 skids off groove 9 and is subject to the extruding of outer casing inner wall, contiguous block 72 inserts away from one end of spheroid and is arranged on initiatively lock core and is parallel to the second keyway 10 of lock core axis under the extruding of spheroid 71, clamping block 72 is joined together to form secondary locking structure by active lock core 2 with by movable lock core 3, theftproof lock, under expendable locked structure and the simultaneous situation of secondary locking structure, is opened by this lock key.
In order to improve the intensity of theftproof lock, the theftproof lock of above-mentioned two kinds of secondary locking 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 in described nested encryptions portion, steady key 4 shape that leads is 7 fonts or approximate T-shaped, during locking, its long limit of steady key 4 of leading is arranged in groove 8 on outer casing inner wall, and its minor face is arranged in by the link slot 24 on movable lock core; When unblanking, the groove 8 described in the disengaging of long limit of the steady key 4 that leads falls into the keyway 6 on active lock core, and its minor face inserts in described shrinkage pool 15 through described link slot 24, realizes the locking of a key (namely lead steady key) many places.When use be similar to T-shaped guiding steady key time, back-moving spring (see Fig. 1) can be set the steady key minor face of guiding is other, make the action of guiding steady key 4 more steady.
For improving theftproof performance further, can select to adopt following preferred scheme: in nested encryptions portion, initiatively plug face has pit or protruding 16, projection or pit 17 is provided with in the bottom of steady key 4 minor face of guiding, in nested encryptions portion, initiatively the surface of lock core can engage each other with the bottom of the steady key 4 of guiding.The advantage of this structure is: when this lock key inserts, and the minor face horizontal stroke of the steady key that leads can insert in shrinkage pool 15 smoothly, realizes unblanking; And when using master key to unblank, initiatively lock core pit or convex surfaces engage each other with guiding steady key 4 minor face, initiatively lock core is stuck, thus prevents active lock core be rotated further and realize secondary locking structure mistakenly and opened by tapered end.Such structure had both been applicable to the aforementioned anti-theft lock end with the steady key of guiding of 7 fonts, was also applicable to the anti-theft lock end of the steady key of guiding with T font.
In traditional anti-theft lock, often adopt flat pearl and spring (or adopting spring separately) as the reposition element of the steady key 4 of guiding, therefore need in the enclosure on wall boring to place flat pearl and spring, this makes the manufacturing procedure of lock body shell complicated, and assembly operation is difficult, for this reason, traditional flat pearl and spring is replaced in the groove 8 that the present invention uses the Rigid Projectiles reed 13 with certain flexibility to be arranged on outer casing inner wall, eliminate the operation that wall is in the enclosure holed in addition, fast easy to assembly, improve production efficiency.Such structure had both been applicable to the aforementioned anti-theft lock end with the steady key of guiding of 7 fonts, was also applicable to the anti-theft lock end of the steady key of guiding with T font.
In order to active lock core 2 is carried out being connected and locating with by movable lock core, in active lock core and the nested encryptions portion that formed by movable lock core, through card hole 25 is offered perpendicular to lock core axis by movable lock core, the draw-in groove 26 of ring-type is offered at the position that active lock core is corresponding with described draw-in groove, card 27 inserts described card hole 25 and described draw-in groove 26, like this, initiatively lock core with linked together on lock core axis direction by movable lock core, and initiatively lock core and can being relatively rotated by movable lock core.
Obviously; the theftproof lock technical scheme of secondary locking structure of the present invention two kinds of forms; no matter whether arrange shrinkage pool 15 on active lock core, no matter also whether intermeshing projection and pit bottom connecting portion surface and the steady key of guiding, be all embodiment and the protection domain of the invention.
