Abstract
An idling-code pairing lock cylinder of an anti-theft door lock comprises an idling lock cylinder body a first-stage lock cylinder, a code pairing lock cylinder a second-stage lock cylinder, a lock cylinder sleeve with two parts, a key, latches, a thrust pin, a code pairing mechanism, a clutch device, a latch spring and the like, and is characterized in that the unlocking as well as the double locking of the anti-theft door lock can be fulfilled through three steps including rotating, pushing and rotating; and when the lock cylinder is locked normally, the idle-running lock cylinder is the same as a common lock cylinder according to a lock used with the idling-code pairing lock cylinder.
Description
Technical field
The utility model relates to a kind of door and uses anti-theft lock core.
Background technology
In the at present used door lock core assembly, lock core is as a whole, with unlocking tool pellet shot from a slingshot is chosen out easily; Keyhole communicates with dead bolt, stirs dead bolt from the outside easily lock is opened, and anti-theft feature is poor, to such an extent as to break-ins case happens occasionally.Coded lock safety, but complicated to sign indicating number, confidentiality is poor.
Summary of the invention
Summary of the invention: the utility model invention, design ingeniously, open method is simple, and confidentiality and theftproof are extremely strong.
The utility model dallies to the technical scheme of sign indicating number antitheft door lock core:
1, in the lock core assembly; Be provided with lock core cover (1), one-level lock core (idle-run lock pin) (2) and secondary lock core (permulation lock core) (3); Pellet shot from a slingshot (13) is loaded on respectively on one-level lock core (2) and the secondary lock core (3); Under the effect of thrust pin (11), the I and II lock core separated with dead bolt (4), can only dally and can not unblank when key inserted.Skilled unlocking also only can rotate one-level lock core (2), and secondary lock core lock core is difficult to rotate.
2, when angle of key rotation; The thrust pin (11) that breach on the secondary lock core (10) and lock core put aligns (promptly to last password time), and hand slightly firmly advances vertically, makes thrust pin (11) through breach (10); Get into annular groove (12) by annular groove (9); Lock core is docked with dead bolt (4) breach, twist key again, lockset is opened.
3, unblank after, continue the twisting key to code position, hand is slightly outwards exerted oneself, and makes thrust pin (11) break away from annular groove (12) and gets back to annular groove (9), forwards original insertions of key again to and extracts and to get final product.This moment, the I and II lock core was all got back to original position.
4, with the operation of common lock core on unblanking, locking on, only increase push (pulling out), to outside the sign indicating number, be convenient to operation.There is not password scale on the panel of lock, strong security.
5, dead bolt and lock core are not penetrating, and external force is difficult for instigateeing.
6, the lock core cover is made as two-segment type, is screwed after lock core (2) (3) is packed into, and lock core is difficult to extract.Jump ring (5), handle (6), driver blade (8) do not have big difference with common lock core.
Description of drawings:
Figure one be idle running to sign indicating number antitheft door lock core assembly figure, idle running each partial structure to the sign indicating number antitheft door lock core has been described, be shown as the state of key when inserting fashion and not advancing vertically among the figure.
Figure two dallies to sign indicating number antitheft door lock core outline drawing, has mainly introduced lock core cover two connected mode partly.
Figure three is permulation lock cored structure figure, has mainly introduced relations such as annular groove on the secondary lock core (3), breach, pellet shot from a slingshot hole, keyhole.
The specific embodiment:
1, key inserts the keyhole rotation, and the thrust pin (11) that breach (10) on lock core (3) and lock core put makes lock core form with dead bolt (4) and connects advancing correct time, and rotating band moving lock tongue rotates again, to open door lock.
2, door lock is opened the continued rotation, and the thrust pin (11) that the breach (10) on lock core (3) and lock core put is to pulling out correct time, and key is axially got back to original position, and row rotates to key radially during original position again, and key can be extracted.
The application Analysis on Prospect: the update new product as door lock core, solved the antitheft problem effectively, and highly versatile, consumption market is widely arranged.
Claims (6)
