Description

Theft-defence alarm with mark spraying device

The utility model relates to a kind of burglar alarm, is a kind of burglar alarm that has the mark jetting system, is applicable to the burglar alarm in important places such as respectively depositing finance, property, firearms and ammunition, and can be cracking of cases important clue is provided.

At present, the burglar alarm that various forms and function are arranged, these alarms can be reported to the police when criminal commits a crime, but often break down or fail to notice alerting signal because of staff carelessness because of alarm, criminal is fled from, and the detection personnel suffer from and do not have ample evidence, cannot not detect brokenly for a long time, cause the criminal at large.

The purpose of this utility model makes main frame spray a kind of marking fluid when reporting to the police for a kind of burglar alarm that has the mark jetting system is provided, and stays the vestige of crime on criminal's skin.

The utility model is to adopt following measure to realize: linking with known alarm host machine is provided with the mark jetting system, this device has a shell that has a cavity, be provided with the film plastic pocket in the cavity pocket of outer cover, in the bag marking fluid is housed, bottom at cavity pocket of outer cover is provided with piston, be provided with the jet propulsion unit of marking fluid in the rearward end of shell, leading section at shell is provided with nozzle, nozzle is made mesh-shape, make marking fluid that bigger projected area be arranged, jet propulsion unit is by base, electric bridge, buster is formed, wherein base is linked by screw thread and shell, buster places in base and the space that piston draws, the break-make of electric bridge is controlled by the relay contact in the main frame, like this, the mark jetting system is linked by lead and main frame, be fixed in the concealed location in important place, when criminal does the warning of case alarm host machine, the relay of main frame inside is charged, the closing of contact, and electric bridge is connected, light buster, buster burning back promotes piston, with the marking fluid ejection, stays the vestige of doing case on criminal's skin, this vestige can keep about 10 days, any method can not be removed, and the person is not had the effect of paying, and the clue of solving a case is provided for the detection personnel.

The utility model and main frame link and also are provided with the emitter of nonfatal irritative gas, and this device sends nonfatal irritative gas and makes criminal do the case ability in forfeiture in short-term when main frame is reported to the police.

The utility model is owing to set up the emitter of mark jetting system and non-fatal irritative gas on existing alarm, irritative gas can take place in alarm when reporting to the police, make criminal do the on-the-spot case ability of doing of losing of case, on its skin, stay after criminal flees from and do the case vestige, for solving a case of personnel of detection provides important clue.

Accompanying drawing 1 has provided the schematic appearance of jetting system;

Accompanying drawing 2 is the inner structure synoptic diagram of jetting system;

Accompanying drawing 3 is the electrical block diagram of used a certain alarm among the embodiment;

Accompanying drawing 4 is the synoptic diagram of gas emitter.

In conjunction with the accompanying drawings the utility model is further described as follows: the utility model is made up of the emitter of main frame, mark jetting system and non-fatal irritative gas.Fig. 3 is the electrical structure synoptic diagram of the used known main frame of present embodiment, the emitter of non-fatal irritative gas also is a known products, only use it in this warning device, the mark jetting system contains the housing 1 of being with cavity, be provided with film plastic pocket 2 in the chamber, fill marking fluid in the bag, be provided with piston 3 in cavity bottom, be provided with the impelling propulsion plant of marking fluid in the rearward end of housing 1, this device is by base 4, electric bridge 6, buster 5 is formed, and base 4 and housing 1 are linked by screw thread, and buster 5 places in the capable space of piston 3 and base 4, electric bridge 6 by lead draw with main frame in relay contact series connection after, be connected in parallel on the two ends of host power supply.After also being in series by the relay contact in lead and the main frame, non-fatal irritative gas emitter 10 is parallel to the two ends of host power supply.Mark jetting system and gas emitter are linked by lead and main frame and be fixed in place hidden and that spray angle is suitable.Like this, do case as criminal and make position switch AN in the alarm host machine and AM action, its normally closed position is disconnected after, alarm host machine is on the one hand through T _3～5And R _3～5On loudspeaker Y, send alerting signal behind the warning circuit of forming, on the other hand triode T ₁, T ₂Conducting, make relay coil J charged, make respectively relay contact 8,9 closures that link with mark jetting system and gas generating unit, electric bridge 6 is lighted buster 5, buster 5 burning backs promote piston 3 marking fluid in the film plastic pocket are released, send non-fatal irritative gas simultaneously, stay and do the case vestige on one's body with on the skin criminal, the gas that sends makes criminal lose the case ability of doing in short-term doing the case scene.
