Abstract
The utility model discloses an electronic alarm theft-proof net, which comprises an anti-theft net 1 and an alarm 5, wherein, the anti-theft net 1 is formed by a supporting frame 4 being connected with railings 3. The utility model is characterized in that the theft-proof railings are hollow pipe fittings, and the inner part of the hollow parts of the railings 3 are connected in series with a conducting wire 2 which can control the alarm 5 to be switched on. The utility model has simple structure, good theft-proof effect, and no shading.
Description
The utility model relates to a kind of safety grid, especially a kind of electronic warning and anti-theft net.
At present, the behavior that utilizes window to steal crime gets more and more, people's preventive means just adds some reinforcing bars or aluminium net etc. in the outside of window, anti-theft effect is undesirable like this, be found if be difficult for again in thief's inlet chamber, want to improve anti-theft effect, must add roughage, this just makes the safety grid clumsiness shut out the light again.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, reports to the police good anti-theft effect, the electronic warning and anti-theft net of not shading and provide a kind of.
The purpose of this utility model can reach by following measure: a kind of electronic warning and anti-theft net, it comprises safety grid, alarm, safety grid is connected and composed by support and anti-theft fence, it is characterized in that anti-theft fence is a hollow pipe fitting, the lead that the hollow interior serial connection one control alarm of anti-theft fence is opened.
The utility model has following base stage effect compared with the prior art: because the utility model is provided with electronic warning system on safety grid, so the utility model good anti-theft effect, and the utility model is simple and light, not shading line.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is a circuit diagram of the present utility model.
A kind of electronic warning and anti-theft net (referring to Fig. 1, Fig. 2, Fig. 3), it comprises safety grid 1, safety grid 1 is made of support 4 and anti-theft fence 3, support 4 is made by angle bar, vertically is connected with anti-theft fence parallel to each other 3 between upper and lower two supports parallel to each other 4, and every 10cm connects 1 anti-theft fence 3, support 4 is passed at the two ends of anti-theft fence 3, and fix with screw, on upper bracket 4, be connected with sunbreaker 11, on the safety grid 1 one deck gauze can be installed.Anti-theft fence 3 is a hollow pipe fitting, serial connection one lead 2 in each anti-theft fence 3 of safety grid 1 hollow, for further antitheft, on the lead 2 that connects between per two pipe fittings 3, be connected with two springs 9 respectively, each spring 9 connects a sheet metal 8, and each sheet metal 8 is abutted against under the effect of spring 9 tension force mutually.Lead 2 and the two ends that are connected across alarm 5 input circuits after resistance R is connected, alarm 5 input circuits are in series with the common base triode BG1 of capacitor C through a base stage, are connected to the alarm lamp 7 and the loudspeaker 6 of output circuit.
When using, upper and lower two supports 4 are fixed on the upper and lower of window, lead 2 causes the short circuit of alarm 5 at ordinary times, alarm lamp 7, loudspeaker 6 are not worked, in case there is the thief to steal, lead 2 is cut off, then power supply is added to alarm 5 circuit two ends, the circuit working of alarm 5, alarm lamp 7 is bright, loudspeaker 6 warning of blowing a whistle.
