Abstract

The utility model relates to an anti-theft screen, belonging to the field of the application of a window screen, the utility model is composed of a metal wire, the outer part of which is coated with soft insulating materials, the metal wire is processed according to the style of the common window screen, and each interweaving point is mutually insulated. No matter robbers use any methods to enter rooms from the sealing place of the anti-theft screen, conducting wires of the antitheft screen can be broken off so that various alarming devices connected with both ends of the conducting wires are triggered. The utility model has mosquito screening and anti-theft functions and thoroughly eliminates the problem that the robbers usually cut the window screen and then use long rod hooks to hook indoor articles, and anti-theft screen has the advantages of strong anti-interference ability, no false alarm, low cost, convenient use, etc. The utility model can be used for directly replacing common door and window screens.

Description

Antitheft screen net

The utility model relates to the door and window mesh screen device of mosquito-insect-proof, and the plain conductor of the soft insulation materials of a kind of outer wrap of saying so more specifically constitutes netted through interweaving in length and breadth.The lead two ends can connect arbitrary break type warning device, when taking place to steal feelings, and whole wire break, thereby the Antitheft screen net of the various warning devices that triggering is attached thereto.

Gauze belongs to the category of window screening class a operation on the door and window, thereby use is more extensive, but window screening of the prior art only plays the effect of blocking mosquito, when it is cut or has a mind to damage, can not export corresponding level signal, is not easy to set up burglar alarm.

The purpose of this utility model is to avoid the deficiencies in the prior art part, under the situation that does not influence former window screening functional performance, provides a kind of effective break signal, so that cooperate with various warning devices.

The purpose of this utility model is realized by following technical scheme.

The utility model adopts the single piece of metal lead of exterior insulation to constitute.

Feature of the present utility model be provided with single lead with soft insulating coating interweave in length and breadth constitute netted, and the place's mutually insulated that respectively interweaves.

When it is cut off or has a mind to damage, solid conductor shows off state.

Experiment shows, the Antitheft screen net that solid conductor interweaves in length and breadth and constitutes, have strong anti-interference performance, rate of false alarm and be zero, with low cost, easy to use, can directly replace the use of common door window screening net.

Accompanying drawing (1) is the utility model structure chart, and accompanying drawing (2) is a schematic diagram.

By the following examples, the utility model will be further described in conjunction with the accompanying drawings.

Embodiment:

Referring to accompanying drawing (1), lead AB is an integrated wire, by the formation gauze that interweaves in length and breadth, the place's mutually insulated that respectively interweaves, lead AB can pass through electric current with after other active device is connected at ordinary times, when being cut off or destroy purposely, lead AB produces and opens circuit, and is exportable break signal at its AB end.

Schematic diagram is arbitrary open type warning device referring to accompanying drawing (2) in the square frame among the figure, and wherein the CD end connects population for sensor, links to each other with Antitheft screen net AB two ends in the present embodiment.Antitheft screen net AB end does not produce and opens circuit at ordinary times, and promptly the D point is a high level, and triode T ends, and the oscillating alarming circuit that the back level is made up of NE555 does not have electricity, and loudspeaker B is sounding not.When Antitheft screen net was cut off or destroys, the AB end produced and opens circuit, and promptly the D point becomes low level by high level, triode T conducting, and late-class circuit gets electric work, and loudspeaker B sends chimes of doom.

Claims

1. Antitheft screen net that adopts plain conductor to constitute, it is characterized in that the plain conductor that is provided with intersects to form netted mutually, and each crosspoint mutual insulating, described lead two ends are with after other active device is connected, under the wire break situation, can export break signal, thereby trigger the active device that is attached thereto.
