Abstract

The utility model discloses a bullet-resisting glass for realizing to launch a counterattack in self-defense; a bearing-capacity layer, a transition layer and a safety protective layer are formed by compounding at least two layers of glass on a counter punching surface and at least one layer of PC plate; when a bullet penetrates through the counter punching surface and breaks the glass, the kinetic energy of the glass is gradually absorbed, and the bullet which is slowed down is retained after hitting the PC plate; when the bullet penetrates through the counter punching surface, the kinetic energy of the bullet is converted into heat energy, and the bullet is shot out after breaking the glass after the PC plate is penetrated out by welding, thereby leading people in the bullet-resisting glass to effectively counterattack and grab thugs, forming the bullet-resisting glass which can be penetrated through along the opposite direction and being widely applied to the occasions such as fanatical and charging places, high-level meeting centers, luxury hotels, museums, consulates, military safety facilities and private villas.

Description

The self-defence bulletproof glass

Technical field

The utility model relates to the glass technology field, relates in particular to a kind of bulletproof glass of launching a counterattack in self-defense realized.

Background technology

In recent years, in the world, threat of terrorism incident constantly rises, and people's life security and property are subjected to very serious threat.And the common bulletproof glass in the known technology, though the ruffian can not come in from external attack easily, the people of glass the inside also can't take the to defend oneself measure of defence has limited the large-scale application of bulletproof glass.

Summary of the invention

For overcoming the existing defective of above-mentioned background technology, it is strong to the utility model proposes a kind of protective capacities, can realize the bulletproof glass of launching a counterattack in self-defense simultaneously.

For achieving the above object, self-defence bulletproof glass of the present utility model by two layers of thickness at least at the glass more than the 4mm with the PC plate holder glue of a layer thickness more than 3mm is compound constitutes bearing layer, transition zone and safe protective covering respectively, but finally form the bulletproof glass of reverse breakdown.

Above-mentioned used PC plate, the case hardness height, scratch resistance is good, has superpower shock resistance and resistance to elevated temperatures, its impact strength is 250～300 times of simple glass, being 20～30 times of acrylic sheet material, is 2 times of safety glass, and in light weight, block when installing not easy fracture, be easy to processing, also have good soundproof effect simultaneously, in conjunction with obtaining excellent effect in the bulletproof glass that is applied to defend oneself.

Compared with prior art, the utlity model has following obvious improvement and outstanding characteristics: the people can be from glass the inside counterattack uniform or self-defence unprincipled fellow, make public security, People's Armed Police etc. to terrorist, the empty strong fright that gives of robbery violence, reduce the occurrence frequency of incident of violence, have structure rationally, the technique effect of design science, solved that traditional glass can only be defended and the technical bottleneck that can not strike back.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is the vertical section structure schematic diagram of the utility model self-defence bulletproof glass.

Among the figure: 1, ground floor glass, 2, second layer glass, 3, the PC plate.

The specific embodiment

With reference to shown in Figure 1, the self-defence bulletproof glass is composited by one deck PC plate holder glue of the layer glass of meeting face A head-on and counterattack face B, the thickness specification is that ground floor glass 1 and the second layer glass 2 of 4mm constitutes bearing layer and transition zone respectively, and the thickness on layer glass right side is the PC plate 3 formation safe protective coverings of 5mm, and wherein glass material adopts safety glass or annealed glass.

Above-mentioned safety glass or annealed glass thickness specification also can adopt 8mm or 12mm, and the bulletproof glass that different structure is made up can be realized the protection of different brackets.

In the practical operation, when bullet passes from meeting face A head-on, when bullet smashed ground floor glass 1 and second layer glass 2, its kinetic energy was absorbed by glass gradually, just had been blocked behind the bullet hits PC plate 3 that slows down, and criminal can't jeopardize the people of bulletproof glass the inside; When bullet passed from fighting back face B, the kinetic energy of bullet was converted into heat energy, at first with PC plate 3 burn throughs, and then the shattered glass ejaculation, make the people of bulletproof glass the inside can effectively strike back, subdue the ruffian, realize launching a counterattack in self-defense.

The utility model self-defence bulletproof glass manufacture craft is simple, material source is easy, protective capacities is strong, application surface is extensive simultaneously, can be used in finance, charge place, high-level meeting center, luxurious hotel, museum, consulate and alert, especially be suitable for and be installed in anti-riot public security police with on the car with occasions such as military safety devices and private savings villas.

The utility model includes but not limited to that the foregoing description lifts, and the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.

Claims

1, a kind of self-defence bulletproof glass is characterized in that: the PC of one deck at least plate by the layer glass at least that is located at the face of meeting head-on and the counterattack face of being located at is compound constitutes for it.

2, self-defence bulletproof glass according to claim 1 is characterized in that: described ground floor glass constitutes bearing layer, and second layer glass constitutes transition zone, and the PC plate is located at the side formation safe protective covering of ground floor glass and second layer glass.

3, self-defence bulletproof glass according to claim 1 is characterized in that: described thickness of glass is more than 4mm, and the PC plate thickness is more than 3mm.
