Abstract
The utility model is composed of a door lock 3, a magnetic switch K1, a magnetic switch K2, an alarm trigger 10 and a battery 9, wherein, the magnetic switch K1 is arranged in the door lock 3, the on-off state of the magnetic switch K1 is controlled by a magnetic steel C1 arranged on a bolt 5, the magnetic switch K2 is arranged on the inner edge of a door 2, and the on-off state of the magnetic switch K2 is controlled by magnetic steel C2 arranged on a door frame 1. When the door is closed and locked normally, an alarm system of the utility model is automatically in the alert state. When the door is opened and unlocked normally, the alarm system automatically cancels the alert state. When the door is opened by force without unlocking, the alarm system can alarm. The utility model has the advantage of convenient operation, the alarm system can be in the alert state whether people in the room or not.
Description
The utility model relates to electronic technology field, specifically a kind of door lock that has warning device.
Present family's door lock does not have warning device, is often forced open the door by the thief and steals into the room.
A kind of warning device is arranged, form by inductor and alarm controller two parts, inductor is installed in indoor gateway next door, alarm controller then is installed in control room or the janitor's room, inductor blocks gateway by infrared light or human inductor, when the gateway of people by having blocked, alarm controller promptly starts warning system, sends chimes of doom.This is at present a kind of advanced burglar alarm, requires indoor people all to leave during use and just starts alarm controller, will close alarm controller earlier before entering house, otherwise can false alarm.Therefore alarm controller to be installed in another chamber.
Use for this warning device being suitable for family, alarm controller is installed in indoor, usually increased by a delayed startup device, promptly to start alarm controller after one short time warning device just come into force, inductor has been sensed the human body short time warning device of also delaying time and has just been sent warning.During use, at first everyone leaves indoorly, and last people speeds away after starting alarm controller.When owner enters house, also to close alarm controller rapidly, otherwise can false alarm.For safety, the switch of this alarm controller generally adopts coded lock or jettron.
There is the following shortcoming in above-mentioned warning device:
1, owner will make sure to keep in mind the password of coded lock or carry hand switch, otherwise can not use;
2, the household must all leave, the burglar alarm when not being suitable for the someone and being in;
3, must speed away behind the startup alarm controller, otherwise alarm starts the generation false alarm;
When 4, the household returns home, close alarm controller rapidly, otherwise false alarm.
The purpose of this utility model is a kind of simple and practical alarm against theft of design, and this anti-theft device utilizes existing door lock automatic switch, need not to be equipped with in addition coded lock or hand switch, easy to use, no matter whether the people is arranged within doors, as long as normally close the door, alarm against theft promptly comes into force.
The utility model is made up of door lock, two magnetic switchs and alarm trigger and battery, wherein a magnetic switch has been installed in the flapper lock, by dead bolt control ON/OFF, when locking, this magnetic switch is for connecting, this magnetic switch disconnects when unblanking, another magnetic switch is installed to the inward flange of door, with a magnet steel control ON/OFF that is installed on the doorframe, at closing time, this magnetic switch is for disconnecting, and this magnetic switch is connected when opening the door, and two magnetic switchs and alarm trigger and battery is connected in series has just formed the utility model.Alarm trigger can be buzzer or tweeter, also can be senior warning device, for example uses radio remote control switch to trigger telephone, is reported to the police to master alarm or to the security personnel by telephone again.
With accompanying drawing the utility model is further described below.
Accompanying drawing is a structural representation of the present utility model.
The dead bolt 5 other magnetic switch K1 that install at two flappers lock 3 install a magnet steel C1 on dead bolt 5, as magnet steel C1 during near magnetic switch K1, magnetic switch K1 is sucked from and disconnects, otherwise when magnet steel C1 left magnetic switch K1, magnetic switch K1 was in the normally closed state that closes; One magnetic switch K2 is installed on limit, door 2 back, a magnet steel C2 is installed in position facing to magnetic switch K2 on doorframe 1, when at closing time, magnetic switch K2 is when the magnet steel C2, magnetic switch K2 is sucked from and disconnects, otherwise, when opening the door, magnetic switch K2 is during away from magnet steel C2, and magnetic switch K2 is in the normally closed state that closes; Magnetic switch K1 and magnetic switch K2 and alarm trigger 10 and battery 9 usefulness leads 7 are connected in series the composition alarm circuit.
Be further described with regard to mode of occupation below.
When door was unlocked, promptly dead bolt 5 did not stretch out, and magnet steel C1 is in magnetic switch K1 correspondence position, and magnetic switch K1 is sucked from, and K1 disconnects, and alarm circuit disconnects, and opens the door or closes the door, and alarm trigger is reactionless.
Shut again when door door lock locked, promptly dead bolt 5 is back-outed and inserted on the doorframe in 1 the dead bolt jack with key, at this moment magnetic switch K2 by the magnet steel C2 on the doorframe 1 inhale from, K2 disconnects, magnet steel C1 on the dead bolt 5 is away from magnetic switch K1, the K1 closure, this be lock a door normally and report to the police on the alert.
Following two kinds of situations are arranged under this state:
1, normal door is promptly unblanked with key earlier, and dead bolt 5 is twisted back in the lock, makes magnet steel C1 near magnetic switch K1, K1 disconnects, and door 2 is pushed open again, and magnetic switch K2 is closure owing to the effect that loses magnet steel C2, because K1 disconnects, alarm circuit disconnects, and alarm trigger is failure to actuate.
2, undesired opening the door promptly unblanks by force door 2 to be opened without key, after door 2 is open, magnetic switch K2 is closure owing to the effect that loses magnet steel C2, and at this moment K1 still is in closure state, and alarm circuit is connected, alarm trigger action, Here it is warning function of the present utility model.
Alarm trigger adopts radio remote control switch, triggers " redialing " key of telephone, is dialed the police emergency number or paging to the owner who goes out automatically by telephone.
The utility model is a simple and practical family or warehouse or industry and commerce burglar alarm, being combined with the flapper lock uses, normally lock at closing time, warning system stands alert automatically, when normally unblanking to open the door, warning system cancellation automatically is on the alert, under the situation of not unblanking to open the door by force, realizes reporting to the police.The utility model is easy and simple to handle, and the indoor people of having does not have can measure warning system per capita on the alert.
