Abstract
The utility model relates to a multifunctional alarm of a security door, and belongs to the field of electronic products. The utility model can automatically sent out an alarm when the security door is prized, shocked, stricken and burned. An alarm circuit of the utility model is composed of a power supply, a switch, a diode, a triode, a resistor, a capacitor, a relay and a horn. The alarm circuit is assembled in a drawer type small box and installed in a sandwich layer of the security door. A main switch of an alarm is controlled by a linkage part of the door lock; a vibration switch and a temperature controlled switch are also arranged in the sandwich layer of the security door. A prizing open triggering reset switch is arranged at the edge part of the security door. The utility model does not give an alarm when the security door is unlocked with a key normally, and the multifunctional alarm of the security door automatically unlocks the switch and electrifies in a state of alert after the door is locked.
Description
The utility model belongs to electronic product, sends the device of warning when antitheft door is subjected to opening sled, vibrations, bump or burns automatically.
Original antitheft door lays particular emphasis on the locking of thickening iron plate, Multiple locking point, and that criminal destroys the method for antitheft door is varied, sled is arranged, pounds, gas welding cutting, sandbag bump etc.People have designed various burglar alarms for this reason.But present burglar alarm mostly is complex structure, expensive warning device.
The purpose of this utility model is to overcome the deficiency of existing security door alarm device, makes it have anti-sled, against shock, anti-gas welding cutting and the multifunctional warning device simple in structure, low-cost antitheft door of opening.
Technical essential of the present utility model: as shown in Figure 1, this multifunctional warning device is by DC power supply, and the K1 switch is the master switch of multifunctional warning device.The positive pole of direct supply is connected with the master switch K1 of warning device; The other end of master switch K1 be connected in parallel reset switch K2, temp control switch K3 and vibration switch K4; The other end of K2, K3, K4 connects the positive pole of diode V1, be connected in parallel 3 pin of resistance R 1 and integrated package of the negative pole of diode V1; The other end of resistance R 1 be connected in parallel base stage and the resistance R 3 of triode V2; The emitter of the other end of resistance R 3 and triode V2 connects the negative pole of power supply: the collector of triode V2 connects resistance R 4, the be connected in parallel emitter of resistance R 2 and triode V3 of the other end of resistance R 4; The emitter of the other end of resistance R 2 and triode V2 and K switch 1, K2, K3, K4 are connected; The be connected in parallel negative pole of 4,8 pin, resistance R 5, relay input end and diode V4 of integrated package of the collector of triode V3; The other end of resistance R 5 be connected in parallel 6,2 pin and the capacitor C 2 of integrated package; The negative pole of another termination power of capacitor C 2; 5 pin of integrated package connect capacitor C 1; The other end of capacitor C 1 and integrated package 1 pin connect power cathode; The positive pole of another input termination power cathode of relay and diode V4; The output terminal of relay connects loudspeaker, the output terminal of relay be connected in series loudspeaker and DC power supply.
Warning device is installed in the door in-core of antitheft door, fixes with the drawer type lid: the interlock inserted link of door lock connects warning device master switch K1; Vibration switch K4, temperature detect switch (TDS) K3 are contained in an in-core, and reset switch K2 is contained in the edge of door; Door lock connects door lock interlock inserted link.
The advantage of this device:, make illegal invasion person dare not continue crime because antitheft door is met vibrations, opens sled, burnt and just can realize reporting to the police.Concrete advantage applies exists: 1, do not report to the police with the key normal door: the back multifunctional warning device of 2, locking a door is opened automatically and switched on and is on the alert: 3, a core and doorframe are pried open 3mm and are then reported to the police; 4, pound or clash into antitheft door with the above power of 3 newton and also report to the police; 5, with gas welding cutting or when setting fire, temperature surpasses 80 degree Celsius and also reports to the police.
Description of drawings:
Fig. 1 is the multifunctional warning device wiring diagram of antitheft door
Fig. 2 is the multifunctional warning device scheme of installation of antitheft door
1. be the K2 reset switch; 2. be the K3 temp control switch; 3. be the multifunctional warning device installation site; 4. be the K4 vibration switch; 5. be door lock interlock control strip; 6. be K1 multifunctional warning device master switch; 7. be door lock; 8. be door lock interlock control skewer bar.
Embodiment:
This multifunctional warning device is installed in antitheft door internal layer with dissection, can power by the 9-15V power supply, the K1 switch is contained under the antitheft door door lock interlock control strip, the control strip control K1 switch of linkage part, control strip is controlled by door lock, and when locking a door with key, the interlock skewer bar in the door drives the control strip and the K1 branch of K1 top and opens, the K1 closing of contact, circuit is logical.At this moment, K2, K3, K4 switch, be not subjected to opening sled, vibrations strike pound or the situation of gas welding cutting under be in the state of disconnection.K4 is a vibration switch, is contained in an in-core, when the vibrations that are subjected to the above power of 3 newton, switch conduction and reporting to the police, K2 are the position, edge that reset switch is contained in door, disconnected by the pressure effect K2 of door, when door and doorframe are pried open 3mm, K2 closure, warning device conducting and reporting to the police.K3 is a temp control switch, and switch conduction is then reported to the police when spending above Celsius 80 with the temperature of gas welding cutting door or baked wheaten cake door.K2, K3, K4 are controlled by K1 all, in the K1 closing of contact, during circuit turn-on, if any the people force open the door, pound the door, the gas welding door, K2, K3, any one switch conduction of K4 all can be reported to the police.Output voltage, diode V14148 by multifunctional warning device gives triode V29013 pressurization, make triode V9013 make it connect the delay circuit of integrated package NE555 by 1K resistance trigger triode V3B562, the G22VF capacitor discharge is arranged, time-delay is more than one minute, and make the work of J relay, for the loudspeaker power supply realizes reporting to the police.
Between multifunctional warning device and K1, K2, K3, K4, reserve 8mm with top hose, be convenient to lead-in wire and connect.Around door in-core both multifunctional warning device, fill rock wool, solved self fire safety problem.When being installed, does multifunctional warning device the drawer type lid of a 150mm * 150mm: lid is fixed with hinge on one side, with small-sized built-in lock fix on one side, realized opening just replaceable battery or safeguard warning device of lock, extraction lid.
