Abstract
The utility model relates to a window burglarproof net with an alarm device. The window burglarproof net comprises a rectangular frame body and burglarproof meshes; the burglarproof meshes are arranged in the rectangular frame body; an elastic hinge is arranged at the lower frame edge of the rectangular frame body; the rectangular frame body is also provided with the burglarproof alarm device; the burglarproof alarm device mainly comprises a power supply, a switch, a red light emitting diode (LED), a green LED, a sound production alarm and a circuit resistor; the red LED and the sound production alarm form a first parallel circuit; the green LED and the circuit resistor form a second parallel circuit; the two parallel circuits are connected in series and then connected with the power supply and the switch through a main circuit; the first parallel circuit also comprises a short-circuit lead; the short-circuit lead is arranged at one end of the lower frame edge; and two ends of the short-circuit lead are connected to the connected position of the first parallel circuit and the main circuit. The burglarproof net is easy to manufacture and safe and convenient to use.
Description
Technical field
The utility model relates to a kind of anti-theft net for window, relates in particular to a kind of anti-theft net for window with warning device.
Background technology
Anti-theft net for window of the prior art scarcely has warning function, and the most technical sophistication of general alarm device, and cost is high, is unfavorable for popularizing.
Summary of the invention
The utility model provides a kind of anti-theft net for window with warning device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-theft net for window with warning device, mainly formed by rectangle framework and safety grid sheet, it is characterized in that: rectangle framework inside is provided with the safety grid sheet, the lower frame of rectangle framework is provided with elastic hinge, on the described rectangle framework burglar alarm is set also, burglar alarm mainly comprises power supply, switch, red light emitting diodes, green LED, sounding alarm, circuitous resistance, red light emitting diodes and sounding alarm consist of the first parallel circuit, green LED and circuitous resistance consist of the second parallel circuit, link to each other with switch with power supply by main circuit after above-mentioned two parallel circuits series connection, also comprise a short-circuit conductors in the first parallel circuit, short-circuit conductors is arranged on an end of lower frame, the two ends of short-circuit conductors are connected in the first parallel circuit and main circuit junction, when not having larceny to occur, red light emitting diodes and sounding alarm are by short circuit, and green LED is bright; When theft occurs, the rectangle framework flips an angle by elastic hinge, short-circuit conductors disconnects, red light emitting diodes and sounding alarm are in parallel, luminous and the sounding alarm of red light emitting diodes this moment is reported to the police, because the resistance value of circuitous resistance resistance value ratio diode is much smaller, the voltage of getting after green LED and the resistance parallel connection is very low, and deficiency is so that green LED is luminous.
Description of drawings
Fig. 1 is normal operating conditions.
Alarm condition when Fig. 2 occurs for theft.
Fig. 3 is Facad structure schematic diagram of the present utility model.
Wherein: L1 is red light emitting diodes, and L2 is green LED, and AB is short-circuit conductors, and R is circuitous resistance, and S is sounding alarm, and 1 is the rectangle framework, and 2 is the safety grid sheet, and 3 is elastic hinge, and 4 is lower frame.
The specific embodiment
Referring to accompanying drawing 1,2, AB is short-circuit conductors in this circuit, when it connects, and red light emitting diodes L
1With sounding alarm S by short circuit, green LED L
2Bright; Be normal condition this moment, when short-circuit conductors AB is broken by the robber, and red light emitting diodes L
1With sounding alarm S parallel connection, at this moment red light emitting diodes L
1Luminous and sounding alarm S reports to the police, because circuitous resistance R is that 30 ohm of resistance than diode are much smaller, and green LED L
2And the voltage of getting after the circuitous resistance R parallel connection is very low, and deficiency is so that green LED L
2Luminous, short-circuit conductors AB is placed an end of lower frame, this moment green LED L
2Bright, expression is without unusual; When having the people to enter, the rectangle framework flips an angle, can break short-circuit conductors AB, and the luminous and sounding alarm S of green LED L1 this moment reports to the police, and plays the effect of warning.Referring to accompanying drawing 3, anti-theft net for window mainly is comprised of rectangle framework 1 and safety grid sheet 2, and rectangle framework 1 inside is provided with safety grid sheet 2, and the lower frame 4 of rectangle framework is provided with elastic hinge 3, and burglar alarm also is set on the rectangle framework 1.
