Description
Technical field
The utility model relates to a kind of lockset, especially a kind of lock that is used on the security door.
Background technology
Employed spring safety lock before comparing, the lock that is used at present on security door, the safety cabinet generally all adopts cross lock core and key, though its security performance is greatly improved, it still exists following many defectives: go out and must be with key, cumbersome, and easily lose; In case key loss or forget just can't be opened the door; Key duplicates easily, has potential safety hazard; For aging old man or child, it is also cumbersome to open the door.The lock that accesses to your password also being arranged, but password is difficult to long-time memory, and easily mixed with other password note.In addition,, be used for last its theftproof and seem relatively poor, therefore can not be directly applied for security door though also have Fingerprint Lock on the market.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of with fingerprint identification technology and automatic control technology combine, convenient and practical, fingerprint anti-theft door lock that safety is good.
For solving the problems of the technologies described above, the utility model fingerprint anti-theft door lock comprises fingerprint sensor, the DSP single-chip microcomputer, lock housing, lock body, power supply, fingerprint recognition control system and relay, lock body comprises handgrip, inside and outside two cams, the Spring Card sheath, driver blade, horizontal locking bolt, on, lower link and latch, fingerprint sensor connects DSP single-chip microcomputer and fingerprint recognition control system, the comparison result output signal of DSP single-chip microcomputer and fingerprint recognition control system links to each other with relay after amplifying, the electromagnet of relay is arranged on the outside of Spring Card sheath, inside and outside two cams coincide and are positioned at the opposite side of spring detent together, the centre bore of cam ring and grip cover lump together simultaneously and rotate, the nose bar of external cam is propped up by the nose bar of cam ring, the inside lower end of driver blade is against on the projection that is provided with on the external cam nose bar, laterally the opposite side riveted and fixed of locking bolt and driver blade together, driver blade is provided with horizontal groove and horizontally slips along this groove, the wheel rim of external cam is provided with a recess, be provided with a projection in the middle of the Spring Card sheath, the two ends of a spring are separately fixed on external cam and the lock-shell lining; Be respectively equipped with horizontally slip skewed slot and upper and lower sliding tray groove on the upper and lower connecting rod, upper and lower connecting rod is movably connected with rivet and driver blade by the skewed slot that horizontally slips, and the upper and lower slip groove of horizontal groove on the driver blade and upper and lower connecting rod is movably combined in together by rivet.
Above-mentioned fingerprint anti-theft door lock, the amplifying circuit that the comparison result output signal of DSP single-chip microcomputer and fingerprint recognition control system is formed via resistance R 1, R2, R3 and two amplifier P1, P2 and capacitor C amplify the back and link to each other with described relay.
Above-mentioned fingerprint anti-theft door lock is fixed with the driver blade left baffle on lock housing.
Adopt the utility model safe-guard door lock of above-mentioned technical pattern, outdoors at closing time with handgrip to the anticlockwise miter angle, the drive cam ring rotates, cam ring drives external cam and also arrives horizontal level to the anticlockwise miter angle, at this moment handgrip and cam ring rely on deadweight to be returned to original position, and the recess on the external cam wheel rim makes it can not get back to original position because of being blocked by the projection in the middle of the Spring Card sheath.This moment, driver blade was also passed laterally by the projection on the external cam nose bar, and drove horizontal locking bolt and upper and lower connecting rod and reach laterally respectively upwards, pass downwards in the lockhole that enters on the doorframe, and this moment, whole lock was locked.By fingerprint sensor finger print information is sent to the fingerprint recognition control system when opening the door, after discerning, makes identical or different result respectively with the fingerprint contrast of storage.If inequality, then do not unblank to relay power supply, refusal; If it is identical, then drive circuit is powered to relay, electromagnet attracts spring detent laterally, projection and the recess on the external cam wheel rim on it are broken away from, external cam is got back to original position under the pulling force of spring, laterally locking bolt and driver blade are passed under the effect of spring force to the inside simultaneously, and laterally locking bolt breaks away from the lockhole on the doorframe, upper and lower connecting rod is also passed downwards and upwards under the drive of driver blade respectively and is broken away from lockhole, and this moment, whole anti-theft device was opened.Rotary handle 45 degree drive cam ring to the right again, and cam ring drives latch and moves inward, and door is opened fully.Fixing left baffle can make driver blade and upper and lower strut move in restricted portion in the lock housing, thereby can other parts of extrusion damage.Therefore, the utility model organically combines the automatic control technology of biological identification technology and electromechanical integration, controls the unlatching of safe-guard door lock according to people's fingerprint.Because everyone fingerprint is unique and can't duplicate, and do not need key or password when unblanking, so its anti-theft security is fine.Save lock core and key in the whole lockset, simple in structure, owner also need not to carry key, only need during use one to press finger gently, simple and convenient, even child old man also can easy for unlocking, also needn't worry key loss in addition or be replicated a series of worries that the back is brought.
