Abstract
An theftproof alarm window with the alarm function which an outer layer glass, a metal mesh, an inner glass are sequence embedded in a window sash, two layer glasses and window sash frame constitute a good airtight enclosed cavity, the differential pressure exists between the atmospheric pressure in the enclosed cavity and the outer atmosphere pressure, the enclosed cavity is communicate with an air-electric converter which is connected to a power supply and an alarm for the integrated circuit, the air-electric converter make the off-on circuit action when the detection atmosphere pressure in the enclosed cavity is significant changed. The airtight of the enclosed cavity is damaged while the outer layer glass or window sash frame is damaged by the thieves so that the pressure significant change is detected by the air-electric converter to make the off-on circuit action to enable the alarm work.
Description
Affiliated technology neck and territory
The utility model relates to a kind of building window that avoids theft, especially a kind of burglary-resisting window that possesses warning function.
Background technology
At present, the anti-theft measure of common window is to take in window to install metal grill or glass and metal grill be embedded in together dependence glass and metal grill stop that the robber enters the room from window in the sash.Metal grill is antitheft to exist the single deficiency of antitheft means but only install, and the robber can use tool for destroying such as long moment reinforcing is cut, severe corrosive chemical solution and means are cut off the destruction metal grill.Also have various warning systems be installed in window, as Iris, but install these warning systems exist the cost height, not easy care, the time deficiency of wrong report arranged.
Summary of the invention
For overcome have now in window or sash, only install metal grill exist single not enough of antitheft means and install and use warning system exist the cost height, not easy care, the time deficiency of wrong report arranged, the utility model provides a kind of anti-theft alarm window, this anti-theft alarm window not only possesses warning function, and cost low, be easy to safeguard, can not false alarm.
The technical scheme that its technical problem that solves the utility model adopts is: in sash, glass outer, metal grill, inner layer glass is embedded in the sash in proper order, the frame of layer glass and sash is formed the closed cavity that tightness is good, there is significant pressure reduction between air pressure in this closed cavity and the external atmosphere pressure, closed cavity and a pneumo-electrical convertor are communicated with, pneumo-electrical convertor and power supply, alarm is composed in series complete circuit, when having a plurality of pneumo-electrical convertor, be in parallel in circuit between each pneumo-electrical convertor, the action of closed circuit takes place all to make when significantly changing in the air pressure of any one pneumo-electrical convertor in the closed cavity that it detected.The robber wants to destroy the glass outer that the metal grill that is installed in the glass outer inboard just must destroy sash earlier under the situation that sash pins, in case the robber has destroyed the glass outer of sash and has just destroyed above-mentioned glass outer, the tightness of the closed cavity that the frame of inner layer glass and sash is formed, owing to have significant pressure reduction between air pressure in the closed cavity and the external atmosphere pressure, so the interior air pressure of closed cavity this moment will take place significantly to change, thereby the pneumo-electrical convertor action make closed circuit that significantly changes that detects air pressure at this moment makes alarm work, had not just exposed it to the open air and steal destruction and have to and stop before the robber does not also further destroy metal grill.Circuit of the present utility model is simple, and less demanding to assembly so be easy to safeguard, only just starts alarm when suffering outside destroy, just do not have wrong report so carry out seal approach.
The beneficial effects of the utility model are, possess anti-theft alarm function and simple in structure, cost is low, be easy to safeguard, can not false alarm.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the front view of anti-theft alarm window embodiment.
Fig. 3 is the A-A sectional drawing of Fig. 2.
1. pneumo-electrical convertors among the figure, 2. power supply, 3. alarm, the 4. frame of sash, 5. metal grill, 6. inner layer glass, 7. glass outer.
The specific embodiment
Pneumo-electrical convertor in Fig. 1 (1) back in parallel is composed in series complete circuit with power supply (2), alarm (3).Be the convenience that guarantees that personal safety and installation and maintenance are used, power supply (2) preferably uses dry cell.
Fig. 2 and embodiment illustrated in fig. 3 in, glass outer (7), metal grill (5), inner layer glass (6) order from outside to inside are embedded in the sash, the frame of layer glass and sash (4) is formed airtight cavity, have significant pressure reduction between air pressure in this closed cavity and the external atmosphere pressure, closed cavity and pneumo-electrical convertor (1) are communicated with.Be connected into complete circuit with power supply (2), alarm (3) again after pneumo-electrical convertor as shown in Figure 1 (1) parallel connection.In order to guarantee the tightness of closed cavity better, the air pressure in the closed cavity preferably is arranged to be lower than the negative pressure state of normal atmosphere (An).
Claims (1)
1. anti-theft alarm window, glass outer, metal grill, inner layer glass are inlayed in proper order and are installed in the sash, the frame of layer glass and sash is formed the good closed cavity of tightness, there is pressure reduction between air pressure in the closed cavity and the external atmosphere pressure, it is characterized in that: the variation that changes the pneumo-electrical convertor detection closed cavity internal gas pressure of making switch motion according to air pressure is installed, and pneumo-electrical convertor is electrically connected with power supply, alarm forms complete circuit.
