Description
Technical field
The utility model belongs to lock assembly, particularly a kind of anti-prizing anti-theft lock core.
Background technology
The general core and the key of pairing, it is that the key both sides are provided with irregular grooving.And the inner system of core that is placed in the sleeve is provided with some core sheets and spring.During use,, make each core sheet of end face ground of grooving push away the block resistance position, to reach the purpose of unblanking with the grooving of key two sides core sheet corresponding to core.But traditional lock core structure is easy to key or tabular tamper tool with homotype, and anti-theft effect is poor.
Summary of the invention
The purpose of this utility model provides a kind of antitheft, anti-prizing anti-theft lock core that pick-proof is effective.
The utility model comprises and is the hollow form lock barrel sleeve, is placed in core, lock pin group and key in the lock barrel sleeve; The lock barrel sleeve lateral wall is provided with at least one groove and the corresponding cover plate that is covered on the groove; In groove, be provided with some lockpin holes; Core one side is convexly equipped with antelabium and key hole, is provided with the corresponding lockpin hole of lockpin hole on some and the lock barrel sleeve in the core sidewall, and core inside provides passage; The lock pin group comprises some lock pins, fore-set and the spring in the lockpin hole that is mounted on lock barrel sleeve and core in regular turn; Surfaces of keys is provided with some deep mixed and corresponding recesses of lock pin group lock pin corresponding to core lockpin hole place.
Wherein:
Core periphery caudal part is arranged with for clasp and buckles the caulking groove of group.
Core key hole both sides are arranged with slot; Nearly root both sides are convexly equipped with and the corresponding and chimeric clamping block of core key hole both sides slot.
Key is the scalariform of tail end convergent.
Be the hollow form lock barrel sleeve owing to the utility model comprises, be placed in core, lock pin group and key in the lock barrel sleeve; The lock barrel sleeve lateral wall is provided with at least one groove and the corresponding cover plate that is covered on the groove; In groove, be provided with some lockpin holes; Core one side is convexly equipped with antelabium and key hole, is provided with the corresponding lockpin hole of lockpin hole on some and the lock barrel sleeve in the core sidewall, and core inside provides passage; The lock pin group comprises some lock pins, fore-set and the spring in the lockpin hole that is mounted on lock barrel sleeve and core in regular turn; Surfaces of keys is provided with some deep mixed and corresponding recesses of lock pin group lock pin corresponding to core lockpin hole place.When locking, by fore-set by the elastic force ejection of spring and tandem arrangement between the lockpin hole of lock barrel sleeve lockpin hole and core, core formed blocking and can't rotate.When unblanking, key hole by core inserts key, make that to be provided with deep mixed recess on the surfaces of keys corresponding with the lock pin of lock pin group, the end of lock pin is included in the recess, push against fore-set simultaneously and compress spring, at this moment, fore-set just is displaced in the lockpin hole of lock barrel sleeve and no longer core is formed blocking, when key, i.e. and rotation lock core simultaneously, so, reaching the purpose of opening lockset, and because the lock pin group is corresponding with the recess of key, its need just can reach the purpose of unblanking by the cooperation of precision, and then make lockset be difficult for being opened by sled, have preferable anti-theft effect.Promptly antitheft, pick-proof is effective, thereby reach the purpose of this utility model.
Description of drawings
Fig. 1, be the utility model decomposition texture schematic isometric.
Fig. 2, be the utility model structural representation stereogram.
Fig. 3, be the utility model structural representation sectional view (locking state).
Fig. 4, be the utility model structural representation sectional view (unlocking condition).
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises and is hollow form lock barrel sleeve 1, is placed in core 2, lock pin group 3 and key 4 in the lock barrel sleeve 1.
Lock barrel sleeve 1 lateral wall is provided with at least one groove 10 and the corresponding cover plate 12 that is covered on the groove 10; In groove 10, be provided with some lockpin holes 11.
Lock pin group 3 is to be mounted in the lockpin hole 11,22 of lock barrel sleeve 1 and core 2, and it comprises some lock pins 30, fore-set 31 and spring 32.Lock pin 30 is to be placed in the lockpin hole 22 of core 2, and the one end extends in the core passage 1, the other end of lock pin 30 and fore-set 31 apical graftings, and the other end of fore-set 31 and spring 32 offset.
Key 4 is the scalariform of tail end convergent, its nearly root both sides are convexly equipped with and the corresponding and chimeric clamping block 40 of core 2 key holes, 21 both sides slots 210, are provided with some deep mixed and lock pin group 3 lock pins 30 corresponding recesses 41 in key 4 surfaces corresponding to core 2 lockpin holes 22 places.
During assembling, at first core 2 is placed in the lock barrel sleeve 1, and lockpin hole 11 aligns on the lockpin hole 22 that makes core 2 and the lock barrel sleeve 1; Lock pin group 3 some lock pins 30 are mounted in the lockpin hole 22 of core 2, organize on lock pin 30 and go here and there to the lockpin hole 11 of lock barrel sleeve 1 fore-set 31 and spring 32 are folded in regular turn again; Cover plate 12 lid of lock barrel sleeve 1 established be fixed on the groove 10; Clasp 25 is buckled in the caulking groove 24 of core 2 tail ends, at last in case assembly is deviate from.
When using operation, as shown in Figure 3, Figure 4, because the lock pin 30 of lock pin group 3 is that appearance is organized in core 2 lockpin holes 22, fore-set 31 and spring 32 are then folded in regular turn to be organized on lock pin 30.When locking, by fore-set 31 by the elastic force ejection of spring 32 and tandem arrangement between the lockpin hole 22 of lock barrel sleeve 1 lockpin hole 11 and core 2, core 2 is formed blockings and can't rotate.When unblanking, key hole 21 by core 2 inserts key 4, make the clamping block 40 of key 4 involutory with the slot 210 of core 2 key holes 21 both sides, make on key 4 surfaces the deep mixed recess 41 that is provided with corresponding with the lock pin 30 of lock pin group 3, the end of lock pin 30 is included in the recess 41, push against fore-set 31 simultaneously and compress spring 32, at this moment, fore-set 31 just is displaced in the lockpin hole 11 of lock barrel sleeve 1 and no longer core 2 is formed blockings, when key 4, promptly while rotation lock core 2 is like this, to reach the purpose of opening lockset, and because lock pin group 3 is corresponding with the recess 41 of key 4, it needs just can reach the purpose of unblanking by the cooperation of precision, and then makes lockset be difficult for being opened by sled, has preferable anti-theft effect.
