Description

Theft-proof electronic door bell lock

The utility model belongs to a kind of electronic anti-theft doorbell lock of daily living article.It is set up corresponding controlling organization and forms on the basis of common spring door lock.

At present, the product of controlling various door switch generally all adopts pin tumbler lock or electronic password lock, the former security insurance poor performance, and it is complete that function is owed, and perhaps the password capacity is little, and the cost height, and trouble is installed." multifunctional safe door lock " (application number 90211196.5) of applicant's application, although very quantum jump is arranged in design, cost has also reduced a lot, but is difficult to be generalized to huge numbers of families.

For the defective or the deficiency that overcome the said goods, it is more complete that the purpose of this utility model provides a kind of function, easy to use, security insurance, and cost is very low, the electronic anti-theft doorbell lock that can protect interior object of certain limit and double as music door-bell to use simultaneously.

Body of the present utility model (1) and lockhole (12) are installed in an interior a certain correspondence position, and doorbell button (8) ［ AN ］ is installed in appropriate location outdoors.Loudspeaker (5) ［ Y ］ and sleep anti-theft switch (15) ［ K3 ］ are housed on the panel (2) of body (1), and the left side of base (16) has 1 through wires hole (7), and pin tumbler lock (4) is housed in the base (16).Battery pack (3) ［ E ］ and circuit board (6), the right flank of the front end protuberate basic unit (16) of pin tumbler lock (4).One side of pin tumbler lock (4) has otch, and gauge tap (10) ［ K1 ］ is housed on the otch, and control panel (11) is housed in the pin tumbler lock (4), and control panel (11) is stirred gauge tap (10) ［ K1 ］ with key turns.Single face insulation copper coin (14) is fixed on locking on the sheet (13) of control panel (11).Pin tumbler lock (4) and insulation copper coin (14) all pass through lead place in circuit plate respectively, after door lock was locked and resetted, the gap that 3mm is only deposited in insulation copper coin (14) on the control panel (11) and pin tumbler lock core rear end constituted switch ［ K2 ］ thus, when lock core was prized 3mm, ［ K2 ］ connected.Circuit board is equipped with 4 triodes ［ G1 to G4 ］ on (6), 1 diode ［ D ］, 1 relay ［ J ］, 1 or 2 integrated ［ IC1, IC2 ］, 5 resistance ［ R1 to R5 ］, 3 electric capacity ［ C1 to C3 ］.

Now in conjunction with the accompanying drawings, operating principle of the present utility model is described further.

One, owner's operating principle of going out to close the door:

1) closes the door: door is drawn close according to a conventional method, and with key pin tumbler lock (4) is locked to reset.Control panel (11) makes contact a, the b conducting of gauge tap (10) ［ K1 ］ with key turns, and a, c disconnect, d, e conducting, and d, f disconnect, thereby the power supply of anti-theft alarm circuit and output are all connected respectively, and the power supply of music door-bell and output all disconnect respectively.

2) force open the door or picking lock is reported to the police: force open the door or when making the lock core rear end retreat 3mm with special instrument picking lock with brute force, connect by the switch ［ K2 ］ that the lock stamen and the insulation copper coin (14) on the control panel (11) of pin tumbler lock (4) are formed, cause G2 and G3 conducting, the J adhesive, the IC1 work of switching on, and, promote Y and send chimes of doom through the G4 amplification.At this moment, even K2 recovers to disconnect, but, rationally select for use C1, R3 just can guarantee that Y continues to report to the police within a certain period of time because the charge-discharge circuit effect that C1, R3 form will be kept G2, G3 and J and continue conducting a period of time.

3) stealing protecting network reports to the police: when arbitrary object was stolen in the shielded serial connection extended protection network (9), ［ SP ］ was disconnected, causes the G1 conducting, also conducting of G2 and G3, and the J adhesive, the IC1 action, Y continues to report to the police.

4) music door-bell all cuts off because of its power supply and output, among the old family nobody the time music door-bell lost efficacy.

Two, the operating principle after owner goes home to open the door:

Open the door: open pin tumbler lock (4) with key according to a conventional method, control panel (11) connects contact a, the c of gauge tap (10) ［ K1 ］ with key turns, a, b disconnect, d, e disconnect, d, f connect, thereby the power supply of anti-theft warning circuit and output are all disconnected respectively, and the power supply of music doorbell circuit and output are all connected respectively.

2) again door is pushed away after owner enters when closing, because of control panel (11) moves, so entire circuit is still kept the duty when opening the door.

3) music door-bell: press AN, IC2 and trigger work, and amplify, promote Y and send music sound, come to show the guest through G4.

4) turn the key in the lock after, even the extended network (9) ［ SP ］ of serial connection disconnects, because of the power supply and the output of anti-theft warning circuit all obstructed, so Y can not send chimes of doom yet.

5) owner can close sleep anti-theft switch K3 just before going to bed, and the power supply of anti-theft warning circuit and output are all connected respectively.When force open the door with brute force or with special instrument picking lock or shielded extended protection network (9) in when still an object is stolen, anti-theft warning circuit conducting work, Y continues to report to the police.Owner disconnects sleep anti-theft switch K3 before opening the door, make the anti-theft warning circuit outage.

Main feature of the present utility model is: 1. reasonable in design, simple in structure, easy to use, and security insurance, cost is very low, and is widely applicable.2. have pick-proof and anti-strong destruction, functions such as extended network protection and double as music door-bell, a tractor serves several purposes has DEVELOPMENT PROSPECT greatly.
