Abstract

The utility model relates to a two-head two-way pair buckled electronic alarm door lock. The utility model comprises two marble lock heads, a pair buckled locking device, a vibration sensing amplification circuit, an acoustic wave sensing amplification circuit, a comparison distinguishing alarm circuit, etc. The pair buckled locking device is extended form the lock bolts in two ways. The utility model is characterized in that if the two lock heads are locked at the same time, a lock body and a buckled box can simultaneously extend the lock bolts, and the lock bolts are buckled and locked with each other; so the anti-prizing and the anti-dialing functions can be realized, and the multiple insurance can be achieved. When the utility model is used, a power supply can be automatically switched on; after the circuit works, the automatic alarm can be given if the lock is prized and the door is broken; the false alarm which is caused by the interference of the strong acoustic wave of the outside world can be reliably prevented. The utility model has the advantages of good anti-breakage performance, safe use, anti-theft function and alarm function.

Description

Two-head two-way paired electronic alarm door lock

The utility model relates to door lock, the anti-electronics newspaper of the two-way make-up of particularly a kind of double end door lock.

Existing commercially available door lock is the monolock header structure, and easily sled, theftproof are poor, do not have warning function.

The purpose of this utility model is to provide a kind of theftproof performance good, does not establish the twin-lock header structure door lock of electronic warning function.

The technical scheme that the utility model solves is such, by two ball lock heads, can two-wayly stretch out the blocking device of the dead bolt formation of make-up, the vibrating sensing amplifying circuit, and sound wave sensing amplifying circuit compares compositions such as discriminant alarm circuit.The twin-lock head is all during locking, and three two-way dead bolts of stretching out close button closing under the buckle device effect, and connect power switch, and circuit enters the early warning duty.The two-way dead bolt that closes button plays the anti-usefulness of allocating for of pick-proof, and when running into metal or other hard thing sled pressures, percussion door lock or door, vibrating sensor is received mechanical oscillation signal, sends chimes of doom after comparing, amplify, differentiating.When the stronger sound wave in the external world caused the vibration of knocker door lock, sonic sensor received signal, through amplifying, differentiated back locking warning circuit, prevented the wrong report that extraneous sound wave causes.

The utlity model has two tapered ends when locking simultaneously, the mutual make-up locking of dead bolt that lock body and button box stretch out simultaneously, pick-proof, anti-ly dial, multiple insurance.Power supply is connected automatically, picking lock behind the circuit working, reports to the police automatically when forcing open the door, and can prevent the interference wrong report of extraneous strong sound wave reliably.Anti-destructive is good, and is safe and reliable, reaches the burglar alarm purpose.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model structure general assembly schematic diagram.

Fig. 2 is the utility model overall structure schematic diagram.

Fig. 3 is the utility model electrical schematic diagram.

Among Fig. 1, Fig. 2, tapered end (1,2), group bar (3,5), dead bolt (4,6), door-plate (7), hand are turned round (8), button bar (9,11), dead bolt (10), push rod (12), button box (13), battery (14), circuit board (15), loudspeaker (16), spring (17).

In Fig. 3 electrical schematic diagram, K switch is connected, after circuit enters the early warning duty, if door, door lock etc. suffer mechanical oscillation such as percussion, sled pressure to do the time spent, vibrating sensor YH receives vibration signal, and converts thereof into signal voltage, amplify through A1, A2 two-stage, A3 filtering after the D1 rectification, is delivered to comparison judging circuit A4.YH is only to the mechanical oscillation sensitivity, and sound wave is insensitive to external world.Sonic sensor TH is only to the sound wave sensitivity, and is insensitive to mechanical oscillation.After extraneous sound is received by TH, after A5 amplifies, deliver to the back level and amplify by the amplifying circuit that D1, D2, A6, A7, T1, T2 etc. form.This amplifying circuit is very low to infrasonic wave's strong sound wave weak signal multiplication factor, and is very high to the strong signal amplification factor of high sound intensity sound wave.Like this, sound wave sensing amplifying circuit is to high sound intensity sound wave sensitivity; To strong sound wave is insensitive in a low voice.TH detects acoustic signals and deliver to comparator A4 after amplification, D4 rectification.If door and lock by sled press, during percussion, YH is very sensitive to this mechanical oscillation, the signal level of signal D1 rectification output after amplifying is higher, TH and back level amplifying circuit to mechanical oscillation and in a low voice strong sound wave do not feel quick, D4 rectification output signal level is lower, through A4 relatively after, the output high level, T3, T4 conducting, IC gets the electric alarm signal of sending, and promotes loudspeaker and send chimes of doom after T5 amplifies.If when causing the mechanical oscillation of door and lock owing to extraneous strong sound wave, TH is very sensitive, back level amplifying circuit multiplication factor is very high, the signal level of D4 rectification output is than the height of D1 output, the A4 output low level, back level warning circuit is not worked, and has so just got rid of extraneous sound wave reliably and has disturbed, and prevents wrong report.

The utility model most preferred embodiment is such, and with reference to Fig. 1, Fig. 2, the lock body is fixedly mounted on behind the door, and tapered end passes door-plate, and locking head connecting rod inserts dialling in the cylindrical void of lock body, inserts the rotatable bar of dialling of tapered end with key, reaches and opens or the locking purpose.During locking, insert tapered end (1) with key, rotate and dial bar (3), dead bolt (4) is pushed in the button box (13), button bar (9) moves toward the direction of arrow; Insert tapered end (2) with key, rotate and dial bar (5), dead bolt (6) is pushed in the button box (13).Dead bolt (6) catch bar (12) and button bar (11) move toward the direction of arrow, and dead bolt (10) inserts in the lock body box under the effect of push rod (12), is fastened by button bar (9), and dead bolt (4) is fastened by button bar (11) simultaneously, reaches two-way make-up purpose.During dead bolt (6) locking, power switch K closure, circuit is connected, and enters the early warning duty.When unblanking, insert tapered end (2) rotation group bar (5) with key and return dead bolt (6), K switch disconnects removing reports to the police, button bar (11) resets under the spring force effect, the button that closes of dead bolt (4) is removed, and inserts tapered end (1) with key again, and rotation group bar (3) is return dead bolt (4) and forced button bar to reset, dead bolt (10) returns under spring (17) power effect that push rod (12) resets in the button box (13), and lock leaves.Element in Fig. 3 circuit is welded on the circuit board (15), and the circuit anode is connected with K switch on the dead bolt (6), and negative terminal connects lock box.
