Abstract
The utility model relates to a fingerprint door lock, which comprises a fingerprint collection head, a fingerprint collection module, a main control board, a liquid crystal display screen, a control keyboard, a key core and a power supply; wherein, a protective window is arranged at the front part of a head cover of the fingerprint collection head, while the other end of the protective window is fixed on the shaft of a step motor; and a lockout knob is arranged at two sides of the key core, while the inner side of the lockout knob is connected with a square shaft with a lock tongue, whereas a convex stand, a positioning sheet and a reset spring are respectively arranged at the outer side of the lockout knob. The utility model has the lockout function, thus the people inside or outside of the door can conveniently and safely use the utility model to lock or unlock the door; and the fingerprint collection window can be well protected, free from pollution and external force damage.
Description
Technical field the utility model relates to a kind of door lock, particularly a kind of door lock of opening by fingerprint recognition.
The door lock that background technology is traditional all is to open with key, significant disadvantages is to lose easily or be replicated, not only dangerous but also inconvenient, in recent years, appearance along with fingerprint collecting and analysis chip, the patented technology that Fingerprint Lock and relevant Fingerprint Lock have occurred is that 02203693 (publication number is 2522249) and the patent No. are the Chinese patent of 01262540 (publication number is 2494866) as the patent No., some technology that come to this.This Fingerprint Lock comprises fingerprint collecting head, finger print acquisition module, master control borad, LCDs, supervisory keyboard, lock core and power supply, master control borad is the microprocessor with storage and calculation function, have in the lock core and be connected with dead bolt and stepper motor that the control lock tonguing goes out, collection head scans fingerprint, signal enters Fingerprint Processing Module, compare with the fingerprint signal of storage, fingerprint matching as fingerprint and storage, then send instruction by master control borad, by the motion of step motor control dead bolt, door lock is opened.But there are two shortcomings in present fingerprint gate lock, the one, and the window of fingerprint collection head is contaminated easily and by outside destroy, and the 2nd, there is not back locking function, use inconvenience, also influence security performance.
The summary of the invention the purpose of this utility model provides a kind of improved fingerprint gate lock, and this door lock has back locking function, and the window of fingerprint capturer can be not contaminated and by outside destroy.
The purpose of this utility model is achieved through the following technical solutions; a kind of improved fingerprint gate lock; comprise the fingerprint collecting head; finger print acquisition module; master control borad; LCDs; supervisory keyboard; lock core and power supply; master control borad is the microprocessor with storage and calculation function; have in the lock core and be connected with dead bolt and stepper motor that the control lock tonguing goes out; it is characterized in that being provided with the protection window in the head-shield front of fingerprint collecting head; be provided with in the both sides of lock core and lock knob; travel switch is housed near the dead bolt; one end of protection window is fixed on the axle of the stepper motor that is connected with master control borad; the inboard knob of locking is fixedlyed connected with the square shaft that drives dead bolt; the knob of locking in the outside is provided with boss; spacer and back-moving spring; boss is positioned at the inboard of lock core fore shell; one end of back-moving spring is fixed on the boss sidewall, and the other end of spacer and back-moving spring is fixed on the inner surface of lock core fore shell.
Said protection window is a metal sheet in the technique scheme, and a side of this plate is porose.The axle of stepper motor can insert in this hole; be fixed by bolts on the metal sheet; when instruction running that stepper motor sends according to master control borad; metal sheet will be that the center of circle rotates to an angle with the motor shaft; block the window of collection head, play a protective role, reverse rotation; then can expose this window, carry out fingerprint collecting.The running of stepper motor is subjected to the control of master control borad, the man-machine interface of this control procedure keyboard that can access to your password.
Said boss cross section is that the garden lacks shape in the technique scheme.When the rotation outside lock knob the time since spacer to boss stop that knob can only turn over certain angle, dead bolt is screwed out because the effect of back-moving spring is unclamped after the hand, knob will be got back to original position.Like this, be installed in locking knob and can only lock a door outdoors, then can not open the door, be installed in the knob of locking in the door,,, also can open the door, both guaranteed safety, use also more convenient so both can lock a door owing to fixedly connected with the square shaft that drives dead bolt.
In the technique scheme.The effect of travel switch is to export a signal when knob is locked in use, and this signal can be closed stepper motor in the lock core by master control borad.Like this, when knob was locked in use, human fingerprint outdoors also can't open the door, and can reach purpose of safety.
The utility model has the advantages that: one, have back locking function, can using easily per capita of indoor and outdoor, safe and reliable; Two, the window of fingerprint capturer can be effectively protected, and is difficult for polluting and being subjected to outside destroy.
Description of drawings Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is that the knob structure schematic diagram is locked in the inboard.
Fig. 3 is that the knob structure schematic diagram is locked in the outside.
Fig. 4 is the structural representation (lateral view) of protection window.
