Description

Electronic theft-proof alarm door lock

The utility model belongs to the E05B door lock assembly.

Material shows according to the relevent statistics, and in China's criminal activity, about 80% is theft crime at present.Therefore the various stealthy activitys of severe strike, the safety that guarantees the country and people's lives and properties is the emphasis in the activity of combatting crime.Burglar alarm is the anti-theft device of using always.The unit that China produces burglar alarm is a lot, and model has BJ-4C alarm etc.But it is pretty troublesome that this alarm 1. uses, and the door and window that is monitored all must be shut before putting into operation every day, notifies the operator on duty use that can formally put into operation then.In running, need pass in and out the gate, must get in touch with the operator on duty earlier, can come in and go out after sounding all clear, otherwise can report by mistake if any the people.2. be easy to be destroyed by the offender.As long as the offender cuts off towards the lead of janitor's room or cuts off the electricity supply, warning system is just malfunctioning.3. warning system is in the power consumption state all the time.

It is equally convenient with common door lock in a kind of use that the purpose of this utility model is to provide, and the theft of forcing open the door can be reported to the police more than immediately, have certain anti-destroy function and can with the electronic anti-theft alarm door lock of extraneous warning system networking.

The utility model is to provide the special door lock that has lock singly-bound 1 in pang the head by (1).Lock the two kinds of duties of through and off that contact or break away from formation lock singly-bound 1, contact 4 and 5 two contacts of motion bar 3 with the dead bolt 2 of singly-bound 1 for lock singly-bound 1.(2) limit switch 7 is installed on doorframe 6, compressing tablet 9 is installed on door 8, contacting or breaking away from of the motion bar 10 of compressing tablet 9 and limit switch constitutes the disconnected of limit switch 7 and leads to two kinds of duties, and contact 11 and 12 is two contacts of limit switch 7.(3) in collection dress capsule 13, relay 14 is housed, sensitive amplifying circuit 15, alarm 16, power supply 17, the two ends of relay 14 coils are in parallel with the positive-negative input end of sensitive amplifying circuit respectively, and contact is respectively 18,19, and an end of alarm 16 is connected with contact 18, the other end is connected with the output 40 of sensitive amplifying circuit, and alarm 16 is reported to the police during the sensitive amplifying circuit output signal; Relay 14 has the normally open contact more than two pairs, and a pair of is 20, and normally open contact is 21 and 22 to two contacts of 20, and another is to being 23, and normally open contact is 24 and 25 to two contacts of 23, can also have the 3rd fourth class normally open contact right in addition.(4) then with contact 5 and contact 11, contact 4 and contact 21 and positive source, contact 12 and contact 22 and contact 18, and power cathode is electrically connected with contact 19 and realizes.

The utility model is compared with conventional art, and there have following advantage 1. to use to be the same with common door lock convenient.2. do not have not power consumption of alert, just report to the police incessantly in case report to the police.3. have the anti-function of destroying, indoor lead of drawing from the lock singly-bound is not in case be afraid of after reporting to the police and cut off, break destruction, cuts off the warning system that from the contact 24 and 25 couple of conductor of drawing then can trigger antitheft networking as attempt with metal object.4 can be that primitive constitutes burglar alarm network widely with the utility model, with less manpower, financial resources warning large areas.

Be described further below in conjunction with the operation principle of accompanying drawing to electronic anti-theft door lock of the present utility model. When door 8 was shut, lock singly-bound 1 closure was contact 4 and 5 short circuits, limit switch 7 open circuits, and namely contact 11 and 12 disconnects, power supply 17 open circuits, relay 14 is not worked, and sensitive amplifying circuit 15 is not worked, and alarm 16 is not reported to the police; In the time of in dead bolt 2 being retracted to lock body 31 with key, lock singly-bound 1 open circuit, contact 4 and 5 disconnects, and limit switch 7 is still opened a way, and alarm 16 is not still reported to the police; Open at the gate, though limit switch 7 closures are contact 11 and 12 short circuits, because lock singly-bound 1 is opened a way already, so alarm 16 is not still reported to the police. But attempt to force open the door by force and enter if any the people, Yin Men closes singly-bound 1 short circuit of locking, when making door 8 displacements make compressing tablet 9 break away from the motion bar 10 of limit switch 7 when forcing open the door, limit switch 7 closures, so power supply 17 consists of the loop by relay 14, contact 21 and 22 short circuits make relay 14 self-lockings, while sensitive amplifying circuit 15 output signal under the voltage of power supply 14, alarm 16 is reported to the police, so just warning is more than for alarm, until the power supply electric energy exhausts. Reporting to the police to the external world in while two contacts 24, the 25 also burglar alarm of short circuit triggering networking, and demonstrates place of alarm (referring to Fig. 7). Because still have the 3rd in the relay 14, fourth class normally open contact pair, the right short circuit of these contacts can trigger all spray paint that is, starts the mechanism such as video recorder and creates conditions for solving a case. Limit switch 7 and the relative distance between the compressing tablet 9 in the utility model are within the specific limits adjustable, with the door that adapts to different closely joint closes with prevent because of the overweight false alarm that causes of knocking at the door. Sensitive amplifying circuit 15 can be integrated circuit, also can be circuit or the integrated circuit that consists of with discrete component Mix the circuit that is connected into discrete component. Sensitive amplifying circuit can be that the monophonic circuit also can be the two-channel circuit.

Fig. 8 is the utility model embodiment preferably, wherein integrated circuit is 32, resistance 33 is for being used for controlling the resistance that integrated circuit 32 null offsets make it working stability, divider resistance 34,35 provides the operating voltage of transistor 36,37, transistor 36,37 is formed the Darlington amplifying circuit, diode 39 is used for stablizing divider resistance 34,35 2 end operating voltages, and loudspeaker is 38.

Have the single grade of button 26 of test usefulness among the embodiment, contact 27 and 29 is a pair of constant close contact of single grade of button 26, and contact 28,30 is a pair of constant open contact of single grade of button 26.Its electric connection mode be in the fragmentary 6 contact 4 with 21 with being connected of positive source after, contact 27 is connected back and power supply with 28 positive pole joins, contact 29 joins with contact 4 and 21, contact 30 and contact 22 and 12 and contact 18 join.
