Abstract

The utility model relates to a bulletproof glass used for preventing from hammering, belonging to the field of anti-riot safety glass manufacture. The utility model is characterized in that the bulletproof glass comprises at least one metal mesh used for preventing bullet shot and hammering with interlayers glued by transparent and sticky elastic adhesive for adsorbing hammering energy and with at least two glass sheet layers and glued with the elastic adhesive. The total thickness of the bulletproof glass is more than 15 mm, and the bulletproof glass can be glued by a solid but more suitable for liquid adhesive. The metal mesh can be replaced by metal strips or wires. The utility model can be used for preventing bullet shot and resisting the hammering of evildoers to prevent indoor robbery. The metal mesh can be led out with electrodes and switched on high or low voltage to prevent the evildoers from touching the mesh by hands.

Description

The bulletproof glass that can resist hammer to pound

A kind ofly resist the bulletproof glass pounded of hammer to belong to anti-riot to make the field with safety glass.

Present bulletproof glass is used for anti-bullet gunslinging, and it is formed with transparent adhesive tape is bonding by two or polylith glass plate, is widely used on the French window of bank, post office, insurance company or dwelling house; Its shortcoming is to prevent that domestic recurrent ruffian from pounding the behavior that cullet are implemented house robbery with hammer.If behind glass, add one deck iron railing again, though can play inhibition, both uncomfortable not attractive in appearance yet.

It is a kind of attractive in appearance, comfortable and have bulletproof glass that anti-hammer pounds simultaneously to reach not only anti-gunshot but also can prevent the effect of ruffian's house robbery that the purpose of this utility model is to provide.

Of the present utility model being characterised in that: it contains: can be shellproof and interlayer with transparent, toughness and can to absorb the elastic gum of hammering energy bonding and the number of plies is at least two-layer glass plies and can prevent hammering into shape and pound and the number of plies is at least the wire netting of one deck with above-mentioned elastic gum is mutually bonding.The described glue that is used for bonding usefulness between glass plies is made of the above-mentioned colloid that flows that is adhered to the strip film around the glass plate and is injected into interlayer through the side direction aperture between two glass plates.Described be used for the glue of bonding usefulness between glass laminate be can be mutually bonding with glass plate film.Described being positioned between two glass plates and with the sticking mutually wire netting of above-mentioned glue also can replace with many one metal wires or metal tape.Described wire netting or metal tape can be to picking out the electrode that a pair of confession links to each other with high or low voltage source.Described wire netting or metal tape can be to picking out the electrode that a confession links to each other with high or low voltage source.Described bulletproof glass gross thickness is at least 15mm.

Use proof: this bulletproof glass has the function that anti-hammer is pounded simultaneously.

In order in conjunction with the embodiments the utility model to be done detailed describing below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Fig. 1: can resist the longitudinal sectional view of hammering the bulletproof glass of pounding into shape when using liquid glue to make bonding agent;

The A-A sectional view of Fig. 2: Fig. 1;

Fig. 3: can resist the longitudinal sectional view of hammering the bulletproof glass of pounding into shape when using the solid film to make bonding agent;

The B-B sectional view of Fig. 4: Fig. 3;

Fig. 5: the cross section view that can resist the bulletproof glass that hammer pounds when using triplex glass-layer of metal net.

Fig. 6: can resist the cross section view of hammering the bulletproof glass of pounding into shape when using four-layer glass, double layer of metal net;

Fig. 7: can resist the cross section view of hammering the bulletproof glass of pounding into shape when using thick-thick-thin common triplex glass, layer of metal net.

Embodiment:

In Fig. 1～2: the 1st, strip Polyurethane film, be bonded in the periphery of the glass plate 7 behind the 5mm, from upper and lower two mutually bonding and accompany the needle-like hand-hole 6 of glass plate 7 sides of wire netting 2 and inject the liquid glue 5 of Polyurethane, after treating that liquid glue 5 is injected into certain altitude, two bonding glass plates 7 are set level gradually make liquid glue 5 be full of the space of interlayer, discharge the air in the interlayer, fixedly form in every way then, with unnecessary film 1 hand-hole 6 is sealed again.Wherein, film 1 also can be a polyvinyl butyral film, and liquid glue 5 also can be SGA.The 4th, from the pair of electrodes that wire netting 2 is drawn through electrode hole 3, can connect high pressure and also can connect low-tension supply, can also can use dc source with exchanging.In the present embodiment; adopt 800 volts of high-voltage DC power supplies; its effect is: when ruffian's hammer is pounded glass and house robbery; because wire netting 2 is arranged in the interlayer of glass plate 7, make of stainless steel wire, thereby be difficult for glass plate 7 is broken; among the moment of desperation; in a single day the ruffian goes to touch net with hand, just can get an electric shock, thereby play the effect that the second layer is protected.

In Fig. 3～4, the 1st, used film among Fig. 1, it sticks together the glass plate 7 that accompanies bonding jumper 2 and constitutes the bulletproof glass of pounding with the resisted hammer of two layers of glass plate, 7 formations, and the 8th, with the single electrode that bonding jumper 2 links to each other, its effect is identical with the bipolar electrode 4 described in Fig. 1.

Fig. 5: the 7th, glass plate, thick middle is 10mm, left and right all respectively is 5mm, accompanies wire netting 2,5th in an interlayer, the liquid glue described in Fig. 1, the 1st, be bonded at the adhesive tape of 7 four jiaos of glass plates, with used identical among Fig. 1.If disregard the thickness of adhesive tape 1, the thickness of bulletproof glass is 5+10+5mm, and the thickness of general adhesive tape 1 is 1mm.Identical in its preparation method and Fig. 1～2.

Fig. 6: different is total four-layer glass sheet 7, and every layer of 5mm is thick, and the bulletproof glass total thickness is 20mm, wherein has two layers of wire netting, and all the other are identical with Fig. 5.

Fig. 7: different is in triplex glass plate 7, has the two-layer 10mm of being thick, and one deck is that 5mm is thick, has pressed from both sides a wire netting 2 therein, and all the other are identical with Fig. 5.Certainly, also can only respectively make for the thick glass of 10mm with two.

From above-mentioned example as can be seen, the gross thickness of bulletproof glass had better not be less than 15mm.

This shows that it not only can be shellproof, and can prevent pounding, can prevent that the ruffian from pounding the cullet house robbery.
