Abstract

A kind of window destruction warning device, including trigger device, alarm, power supply, the trigger device, alarm and power electric connection in circuit, when the trigger device is triggered, make the alarm work.The trigger device is conducting wire, is connected in circuit, when the conducting wire is cut, connects branch where the alarm, institute's alarm work.The conducting wire is passed through from the hollow window edge of burglary-resisting window, it is therefore desirable to be passed through from each hollow window edge.

Description

A kind of window destruction warning device

Technical field

The present invention relates to a kind of warning devices more particularly to a kind of window to destroy warning device.

Background technique

With the anti-theft security consciousness constantly enhancing of people, either high-rise building, agriculture residence one-storey house is still done business retail shop, base Burglary-resisting window is assembled on this for antitheft, a possibility that reducing pivot frame burglary in certain level.It is reported that nowadays Burglary-resisting window on the market is the hollow window edge of stainless steel mostly, advantage be it is easy for installation, price is lower.The disadvantage is that material is in certain journey Deformation and fracture are easy to occur under the external force of degree.Under normal circumstances, for the burglary-resisting window of stainless steel material, theft suspicioner Using the tools such as pipe wrench just can soon by window edge expand or cut, after enter the room implementation theft, and expand or cut The sound of very little is substantially only issued in the process, and indoor personnel or neighbours are difficult to find burglary-resisting window and are destroyed, this is greatly The security of the lives and property for having threatened the people of degree.

For the shortcomings of existing burglary-resisting window, there is an urgent need to the device that one kind can install alarm on burglary-resisting window, Theft suspicioner implements triggering in time during destroying burglary-resisting window and alarms, and plays the property safety of the protection people, prevention Delinquent effect.

Summary of the invention

Insufficient in view of the above technology, the present invention proposes that a kind of window destroys warning device.

A kind of window destruction warning device, including trigger device, alarm, power supply, the trigger device, alarm and electricity Source is electrically connected in circuit, when the trigger device is triggered, makes the alarm work.

The trigger device is conducting wire, is connected in circuit, when the conducting wire is cut, is connected where the alarm Branch, institute's alarm work.

The conducting wire is passed through from the hollow window edge of burglary-resisting window, it is therefore desirable to be passed through from each hollow window edge.

For the invasion that preferably avoids theft, thief is avoided only to be bent invasion of the window edge without cutting window edge, it is described Trigger device uses the close and discontiguous conductor of two root distances, and the conductor is passed through from the hollow window edge of burglary-resisting window.Work as robber When surreptitiously people is bent window edge, it can also be bent this close and discontiguous conductor of two root distances simultaneously, when the conductor bends, It can be in contact between two conductors, to connect branch where the alarm.

The trigger device is the combination of bracing wire and switch, and the bracing wire is passed through and drawn from the hollow window edge of burglary-resisting window Tightly, one end is fixed in window edge, and the other end and the switch are mechanically connected, and the switch is fixed on window, and the switch is Single-pole double-throw switch (SPDT), the switch is in an intermediate position in free state, separately has pretightning force application to keep the switch oriented The trend of one of contact closure.

When window edge is bent, the bracing wire elongation pulls the switch, is allowed to be closed, connects where the alarm Branch.

When window edge is cut, the bracing wire and the pretightning force disequilibrium on the switch, pretightning force can make described hold It closes and closes, connect branch where the alarm.

Specific embodiment

Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.

Embodiment one

As shown in Figs. 1-2, a kind of window destroys warning device, including trigger device, alarm, power supply, the triggering dress Set, alarm and power electric connection in circuit, when the trigger device is triggered, make the alarm work.

Trigger device is conducting wire 1, is passed through from the horizontal rib 3 and perpendicular rib 2 of burglary-resisting window, the both ends of conducting wire are respectively connected in circuit The end a and b.The grid of VMOS field-effect tube VT, the short circuit of source the two poles of the earth, VT are in off state, and loudspeaker B does not work without electricity at this time.It will When conducting wire is cut off by external force, VT will obtain grid bias-voltage and saturation conduction, and loudspeaker B is obtained electric at this time, is sounded an alarm.

Embodiment two

As shown in Figure 3,4, on the circuit base of embodiment one, trigger device is close without contacting using two root distances Conductor, the conductor 4 is placed in the hollow window edge of burglary-resisting window.And be supported in window edge by support 5, two conductors are respectively connected to The end a and b of circuit can also be bent this close and discontiguous conductor of two root distances simultaneously, work as institute when thief is bent window edge It when stating conductor and bending, can be in contact between two conductors, to connect branch where the alarm.

Embodiment three

As shown in Figure 5,6, on the circuit base of embodiment one, trigger device uses the combination of bracing wire and switch, draws The lower horizontal rib of burglary-resisting window is fixed in one end of line, after passing through perpendicular rib, is connected to out after the guide wheel 7 being fixed on burglary-resisting window On the switch arm 12 for closing body 11, switch is fixed on window.The switch is single-pole double-throw switch (SPDT), and circuit is accessed in in-between contact In a point, the b point in circuit is all accessed in another two contact.Switch is in an intermediate position in free state, has one separately around leading The weight of wheel switchs the trend that oriented contact 2 10 is closed.

When window edge is bent, bracing wire elongation, Drawing switch arm is closed switch to contact one, connects the alarm Place branch.

When window edge is cut, bracing wire and the weight pretightning force disequilibrium switched are switched and are closed to contact 2 10, connect Branch where leading to the alarm.
