Abstract
The utility model relates to an anti-theft alarm which is used on doors. A novel anti-theft alarm solves a problem that the anti-theft alarm can dial numbers to alarm under the condition that a door is opened abnormally. The anti-theft alarm is characterized in that a main circuit comprises a switch which is fixed to one side of a door pivot, wherein one end of the switch is connected with a power supply, and the other end is connected with the power supply after connected with a switch, a relay normally-open switch, an electromagnet, and an infrared remote-control switch in series respectively. The anti-theft alarm has the advantages of simple structure and reasonable design. The anti-theft alarm can be arranged on a vehicle door conveniently, and is used for vehicle anti-theft alarming. The anti-theft alarm can also be used for the anti-theft alarming of family house doors and the anti-theft alarming on safes.
Description
Technical field
The utility model relates to a kind of burglar alarm.
Background technology
In order to solve the antitheft problem in automobile, residence, the burglar alarm of people's design, a kind of garage door burglar alarm is disclosed as Chinese patent CN2302170, by open circuit, short circuit, alarm circuit form, or by another kind open circuit, alarm circuit forms, be installed on the garage door and automobile on, wired contact, can report to the police at in-house operation, remind the car owner to prevent that car is stolen.
The objective of the invention is: a kind of automobile, proof box and door of being applicable to is provided, under improper situation, opens the novel anti-theft alarm of Men Shike automatic dialing alarm.
The technical solution that realizes the foregoing invention purpose is such:
A kind of novel anti-theft alarm comprises switch 4 in the switch 2 that is fixed on door pivot one side, the circuit), relay normally open switch 5, mobile phone 9, it is characterized in that:
Switch 2 one ends that are fixed on door pivot one side connect power supply, and the other end connects power supply 1 behind tandem tap 4, relay normally open switch 5, electromagnet and the infrared telecontrol switch 12 respectively;
The utility model is simple in structure, and is reasonable in design, can be installed in easily on the arrangements for automotive doors, is used for automobile anti-theft alarm; But the novel anti-theft alarm that also can be used for the automatic dialing alarm on family's door burglar alarm and the proof box.Dialing alarm both can realize that notice in person, also can realize notifying public security department.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, a kind of novel anti-theft alarm comprises switch 4, relay normally open switch 5, mobile phone 9 in the switch 2 that is fixed on door pivot one side, the circuit.
Switch 2 one ends that are fixed on door one side connect power supply, and the other end connects power supply 1 behind tandem tap 4, relay normally open switch 5, electromagnet and the infrared telecontrol switch 12 respectively.
In the use, this device can be installed on the automobile door.
Under normal circumstances, when owner leaves in short-term, or when wanting to use automobile, owner can cut-off switch 4, or disconnects infrared telecontrol switch 12, and burglar alarm just quits work.
Under the improper situation, when the owner of automobile need start burglar alarm on the car, as long as switch 4 and infrared telecontrol switch 12 closed burglar alarms just are activated.When arrangements for automotive doors is opened under improper situation, closed after the switch 2 that is pushed by car door moves under the effect of spring 3 originally.Relay 15 must electronicly be done, the normal open switch 13 of relay will along with the actuating of relay become from original often opening normally closed, time relay coil 16,17,18 timing simultaneously.At this moment because the closure of relay switch 13, relay 19 will get electronic work, relay normally open switch 5 will move simultaneously, by often open become normally closed, magnet coil 7 energisings, because electromagnet 8 energisings obtain magnetic, attract armature 11 to move downward, drive contact and move downward together, contact knocks the dial key 10 of mobile phone 9, when reaching the time (as 1.5 seconds) that button is pressed, time relay coil 16 reaches timing time and begins action, and simultaneously, switch 21 actions are often left by normally closed becoming, relay 19 power interruption recovering original states, at this moment switch 5 also will return to original normally open by normally closed.Main circuit just is disconnected, magnet coil 7 outages, and electromagnet will lose magnetism, and armature 11 is returned to original state under the effect of spring 6.Realize by this preset number in the mobile phone is opened.When armature 11 drove contacts and gets back to original position, time relay coil 17 timing times finished (as 2.5 seconds) and also begin action, and time relay switch 20 follows by action simultaneously, by often opened originally become normally closed.Relay 19 energising action again, relay switch 5 again by often open become normally closed, electromagnet obtains magnetic again and attracts armature 11 to move downward the dial key that the drive contact knocks mobile phone once more, number to this owner who just owner on the mobile phone is stored is in advance transferred to, at this moment owner will get signal, know that the arrangements for automotive doors of oneself opened by the people under improper situation, can report to the police immediately.
After signal is transferred to, the time relay 18 usefulness timing times finish (as 3.5 seconds) and begin action, switch 14 is also along with action is opened by normally closed often becoming, relay 15 and time relay coil relay return to original state, each relay switch and when continuing the device switch also return to original state, switch 5 returns to normally open, the main circuit outage, magnet coil 7 outages lose magnetism, and armature 11 breaks away from mobile phone 9 dial keies again under spring 6 effects, return to original state.
After entering, the personnel that illegally enter shut the door immediately, just switch 2 is disconnected, do not influence the normal function of burglar alarm yet, because at this moment relay 15 electronic work, relay switch 13 by often open become normally closed, so at this moment the closed action of the actuation of an alarm of burglar alarm and switch 2 is irrelevant, changed into directly related with relay switch 13, guaranteed the functional reliability of burglar alarm.
