Abstract

The utility model relates to an anti-theft alarm iron door, composed of pipes. A door frame and a door leaf side column are provided with photoelectric switches and mechanical contact electronic switches. Mechanical contact electronic switches are arranged between two iron plates at the middle part of the door leaf and between the door frame and a wall. A hollow rail of the door leaf is provided with conducting wires which can alarm when the conducting wires are broken. A door lock is provided with an electronic switch which is linked with the door lock and can stop an alarm circuit when the door is opened normally and parallel resistors. The alarm circuit can be triggered to alarm when any switches and the conducting wires are broken. The hollow characteristic of the pipes is used by the anti-theft door for the omnibearing defense distribution, and the alarm is timely and reliable.

Description

The burglar alarm iron gate

The utility model relates to a kind of burglar alarm iron gate.

The Theft-proof iron door great majority of having produced at present do not possess warning function, pry open iron gate and enter the behavior that dwelling house steals and happen occasionally, and Theft-proof iron door does not reach antitheft purpose.And the alarm iron door of now having invented, or, or because reliability of contact is poor, makes warning device be easy to destroyed or walk around and do not reach the effect of warning because its warning trigger point is arranged not comprehensively.

The purpose of this utility model will provide a kind of exactly and deploy troops on garrison duty comprehensively, but the secondary warning, and the survivable burglar alarm iron gate of alarm.

Be the burglar alarm iron gate of realizing that this purpose the utility model is designed, doorframe 1 that is made of tubing and door leaf 2 and existing warning circuit constitute, two iron plates 10 before and after having in the middle of the door leaf 2, and iron plate 10 is hollow railing 9 up and down.Optoelectronic switch SW5 and mechanical contact electronic switch SW1 in the warning circuit are installed on doorframe 1 and door leaf 2 side columns, some mechanical contact electronic switch SW2 are installed between two iron plates 10, some mechanical contact electronic switch SW3 are installed between doorframe 1 and body of wall 3, are installed with the lead 12 of connecting in the hollow railing 9 with above-mentioned electronic switch SW1, SW2, SW3.When this burglar alarm iron gate was subjected to intense impact or is prized, optoelectronic switch SW5 misplaced, and can trigger warning circuit and send the first road chimes of doom; When door is pried open electronic switch SW1 disconnect, when hollow railing lead 12 when sawed-off fractures, electronic switch SW2 disconnected when iron plate was split, SW3 disconnected when doorframe 1 was split, all can trigger warning circuit and send the second road chimes of doom.And the electronic switch SW4 that is installed in two door locks 11 between the iron plate 10 and above-mentioned warning circuit links together, electronic switch SW4 and parallel resistance R all design on door lock 11, electronic switch SW4 disconnects when normal door, the resistance R place in circuit cuts out warning circuit and quits work, close electronic switch SW4 closure behind the door, make resistance R short-circuit alarming circuit begin monitor alarm.

The utility model has the advantages that in available places such as doorframe and door leafs and be furnished with alarm switch and warning wire comprehensively, no matter the burglar destroys where all can trigger warning, and optoelectronic switch just can trigger warning when not destroying as yet and if only if security door is subjected to impacting, thereby reports to the police in time, and is reliable.Simultaneously owing to will control the electronic switch SW4 and the parallel resistance R of warning circuit work and design on door lock 11, and be enclosed in two iron plates 10, so the burglar can not block the lead at electronic switch SW4 two ends earlier and keep the resistance R place in circuit and close warning circuit, blocking other position lead chimes of doom will be constant.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural configuration schematic diagram of the utility model burglar alarm iron gate.

Fig. 2 is the schematic diagram that optoelectronic switch SW5 and mechanical contact electronic switch SW1 are installed in doorframe and the door leaf side column.

Fig. 3 is the schematic diagram that mechanical contact electronic switch SW2 is installed between door leaf two iron plates.

Fig. 4 is the schematic diagram that mechanical contact electronic switch SW3 is installed between doorframe pipe and the body of wall.

Fig. 5 is the warning circuit structured flowchart.

Warning circuit can adopt various available circuits to reach the warning purpose, wherein mechanical contact electronic switch SW1, SW2, SW3, security door by lead 12 series connection back places in circuit destroys detecting unit 4, with insert door lock control module 5 behind the electronic switch SW4 parallel resistance R of door lock 11 interlock, optoelectronic switch SW5 inserts photoelectric displacement detecting unit 6, send chimes of doom by siren 7, power supply 8 provides power for circuit.

The utility model key is above-mentioned warning electronic switch and lead comprehensively deploying troops on garrison duty on the doorframe door leaf.As seen in the side column tubing of doorframe 1 and door leaf 2, optoelectronic switch SW5 is housed by accompanying drawing, when door be subjected to intense impact, when prizing, doorframe 1 and door leaf 2 side columns can produce displacement, when this displacement causes two aperture dislocation of optoelectronic switch, optoelectronic switch SW5 works, photoelectric displacement detecting unit 6 detects this signal, and siren 7 sends the first road chimes of doom.Mechanical contact electronic switch SW1 also is installed on the side column of doorframe 1 and door leaf 2, when door is closed, mechanical contact returns to door leaf 2, electronic switch is connected, when door was pried open, mechanical contact ejected door leaf under the effect of spring, and electronic switch SW1 disconnects, destroy detecting unit 4 and detect this signal, siren 7 sends the second road chimes of doom.In like manner, between two iron plates 10 of dress lock several electronic switches SW2 is housed in the middle of door leaf, two iron plates, 10 compressing electronic switch SW2 connect its compressing under the normal condition, when the people takes iron plate apart, the compressing of electronic switch SW2 disappears, and electronic switch disconnects, and siren 7 sends chimes of doom.Some electronic switch SW3 are housed between doorframe 1 and wall 3, and when door was fixed on the wall, the compressing electronic switch was connected it, and the compressing of electronic switch disappears when the people tears open, and electronic switch disconnects, and makes alarm send chimes of doom.In the hollow railing 9 of door leaf, be installed with lead 12, when railing is cut off, must cause lead 12 wherein to open circuit, thereby send chimes of doom.Electronic switch SW4 and parallel resistance R are housed on door lock 11, SW4 and door lock 11 interlocks, SW4 off resistance R place in circuit during normal door, warning circuit is closed in 5 controls of door lock control module, close behind the door that the SW4 closure makes the resistance R short circuit, warning circuit enters the normal monitoring alarm condition.Resistance R is installed in avoids the burglar to cut off the connecting conducting wire of electronic switch SW4 and make warning device malfunctioning on the door lock, can cause the resistance R loop to disconnect because cut off lead, thereby cause chimes of doom, so the alarm of this layout is survivable.
