Abstract

The utility model particularly relates to an alarming anti-theft net beneficial to fire fighting. The utility model comprises a window frame and an enameled wire, wherein a frame body of the window frame is provided with hooks which can space a definite interval in a molding way, the enameled wire can encircle the hooks to wind into a net-shaped anti-theft net, and both ends of the enameled wire are connected with an alarming control device. The utility model has the advantage of low cost. Moreover, the utility model not only can have anti-theft function, but also can be the anti-theft net beneficial to fire fighting.

Description

But a kind of alarming anti-theft net that helps fire-fighting

Technical field:

The utility model relates to the anti-theft device technical field, but refers in particular to a kind of alarming anti-theft net that helps fire-fighting.

Background technology:

At present from household, management place to the industrial building, for the antitheft iron and steel safety grid of all having erected different shape, though it has played effective antitheft effect, but the people can't escape from window when running into fire alarm, fire fighter and fire-fighting equipment also can't be from the disaster relief in the window inlet chamber, therefore tend to cause the miserable scene of each, the loss of life and property is extremely heavy, and this safety grid shape has also influenced the outward appearance of building.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of cost lower, has both had anti-theft feature, but help again fire-fighting the alarming anti-theft net.

For achieving the above object, the technical scheme that the utility model provides is: it includes window frame, form the hook of a determining deviation at interval on the framework of window frame, an enamel-covered wire is wound in netted safety grid around hook, and the two ends of this enamel-covered wire are connected with alarm control unit.

The enamel-cover line selection is very fragile but the well behaved diameter of switching on is 0.32mm is best.

Safety grid of the present utility model is to adopt the enamel-covered wire braiding, the surface is non-conductive, enamel-covered wire is colluded for a short time around the stainless steel of making the window frame handle position of window (reserve switch) with stainless steel tube and welding a determining deviation, enamel-covered wire and window frame reach to collude all for a short time and are made at state of insulation, each window net has only two cable ports of head and the tail, and can be together in series the fenestrate net port in whole layer building, becoming the big loop of a low pressure net, at this moment can both report to the police with any one window broken string of first floor.These netting twines are because a little less than being highly brittle, when fire alarm took place, the people had no to stop toward the operation turnover of escape or fire-fighting equipment outside window, such safety grid does not influence outward appearance, save resource, power consumption is also very little, and object is past in simultaneously can also Control Room steals outside window.Therefore, the mode that the utility model adopts little shape traverse net work to take precautions against warning is unblocked when fire-fighting, also reaches antitheft effect simultaneously.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model alarm control unit circuit diagram.

The specific embodiment:

Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further, see shown in the accompanying drawing 1, this preferred embodiment includes window frame 1, form the hook 2 of a determining deviation at interval on the framework of window frame 1, be wound in netted safety grid by enamel-covered wire 3 around hook 2, it is the very fragile but functional enamel-covered wire 3 of switching on of 0.32mm that present embodiment is selected diameter for use.The two ends of this enamel-covered wire 3 are connected with alarm control unit.

Operating principle of the present utility model is (seeing shown in the accompanying drawing 2):, 220V economize on electricity power supply is supplied with the window net group that the 12V low-tension current is made into for no fracture by transformer B, all connect with series system between each window net, the relay magnetic coil of connecting is again formed the closed-loop path.The normally closed switch contact K of relay LJ ₁Warning lamp 4, the siren 5 of voltage confession of economizing on electricity of connecting, after power switch K connected, the loop of window net made relay LJ work, K ₁At open-circuit condition, warning lamp 4, siren 5 are not worked, and when the window net is broken for any one section, low tension loop is interrupted, relay LJ dead electricity, K ₁Closure, warning lamp 4, siren 5 work are reported to the police.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.

Claims

But 1, a kind of alarming anti-theft net that helps fire-fighting, include window frame (1), it is characterized in that: form the hook (2) of a determining deviation at interval on the framework of window frame (1), be wound in netted safety grid by enamel-covered wire (3) around hook (2), the two ends of this enamel-covered wire (3) are connected with alarm control unit.
