Abstract

The utility model discloses a glass dismantling device, in particular a toughened glass dismantling device. The toughened glass dismantling device comprises a high-pressure gas generation device (1), a glass breaking head (2), a shell (3) and a controller (4), wherein one end part of the shell (3) is provided with an opening (5); the size of the tip of the glass breaking head (2) is adaptive to the size of a hole (5); the side wall of the tail end of the glass breaking head is in sealing contact with the inner wall of the shell (3); and the high-pressure gas generation device (1) is arranged between the tail end of the glass breaking head (2) and a rear seat of the shell (3) and is connected with the external controller (4). The self structure of the glass dismantling device is not damaged and no fragments are produced when the glass dismantling device is used. In addition, the broken toughened glass can be prevented from generating high-speed splash and hurting people. Meanwhile, the glass dismantling device is free from national control articles, such as explosives and detonators and can be used at ease in the public occasions.

Description

Safety glass orcible entry device

Technical field

The utility model relates to a kind of glass provision for disengagement, is specifically related to a kind of safety glass orcible entry device.

Background technology

At present, most large-size air conditioning mass transportation facilities, train, subway etc. all adopt the confined space structure, only offer a small-sized ventilating opening at the top, and safety glass is as the hermetyic window main material.In case breaking out of fire or other traffic accident in the car; The broken glass hammer that vehicle is equipped with also is not easy to break glass; Dense smoke in the confined space will make the people suffocate rapidly, cause people in confined space, to escape, and cause the dead crowd of crowd to hinder accident; At present international, the domestic generation a lot ofly goes out because of breaking window immediately, causes the accident of great casualties.

Present in addition most of markets also adopt safety glass as glass curtain wall, when emergencies such as this type market breaking out of fire, because outlet contraction or passageway for fire apparatus are stopped up, the dead crowd of crowd is also often taken place hinder accident; And some high building exterior wall integral body all are safety glass now, in case its inside breaking out of fire, the fire fighter can't be outside the building sprinkling fire, can only get into scene of a fire internal firefighting, this all causes significant impact for life safety and fire extinguishing progress of fire fighter.

Destroy the broken glass device of safety glass on the market with blasting method, self brisance when being to use is big, hurts sb.'s feelings easily; The 2nd, glass a large amount of High Speed Flyer that can fly out are hurted sb.'s feelings equally easily during explosion safety glass; The 3rd, the explosion article belong to national high safety control article, are limited in the public place and use, and are unfavorable for promoting the use.

The utility model content

The utility model has overcome the deficiency of prior art, and a kind of safety glass orcible entry device is provided, and has solved the generation emergency and can't destroy high-strength armoured-glass timely and effectively, cause damage and injures and deaths, and the problem that existing broken glass device is hurted sb.'s feelings easily.

For solving above-mentioned technical problem, the utility model adopts following technical scheme:

A kind of safety glass orcible entry device; Comprise gases at high pressure generating means, broken glass head, shell and controller; One end perforate of described shell, the most advanced and sophisticated size and the described hole of broken glass head are suitable, and the terminal sidewall of broken glass head contacts with the inner wall sealing of shell; Described gases at high pressure generating means is arranged on brokenly between the back seat of end and shell of glass head, and links to each other with the controller in the external world.

For making the utility model play better technique effect:

Technical scheme further is that the end concave of above-mentioned broken glass head is curved; Under the effect of gases at high pressure generating means, produce high temperature, gases at high pressure; The edge of arcuate end is outwards pushed by radial load, forms self sealing structure, avoids high temperature, pernicious gas to leak.

Technical scheme further is that the terminal middle part of above-mentioned broken glass head is provided with blind hole; Regulate and control the high temperature of gases at high pressure generating means output, the pressure of gases at high pressure through the volume of blind hole; The surge pressure of effective attenuation gases at high pressure; Realize the self-adapting seal between gases at high pressure generating means, broken glass head, the shell, ensure the deformation of shell non-plastic simultaneously.

Technical scheme further is that the tip of above-mentioned broken glass head is fixed with diamond, steel alloy or cubic boron nitride; Improve the toughened glass crushing success rate; Even also can guarantee successfully the orcible entry rate for 15mm, 19mm thickness safety glass; And after safety glass orcible entry device used, broken glass head was most advanced and sophisticated harmless.

Technical scheme further is the above-mentioned interior dress of gases at high pressure generating means gases at high pressure propellant, and the high temperature and high pressure gas that utilizes the moment burning of gases at high pressure propellant to produce drives and breaks the glass head.

Compared with prior art; The beneficial effect of the utility model is: this body structure did not have destruction when the utility model not only used; No fragment produces, and broken safety glass generation is splashed at a high speed, avoids hurting sb.'s feelings; There are not national regulated items such as explosive, detonator in the utility model simultaneously, can relieved in public places use.

Description of drawings

Fig. 1 is the utility model embodiment one structural representation;

Fig. 2 is the utility model embodiment two structural representations.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

Embodiment one:

As shown in Figure 1; A kind of safety glass orcible entry device comprises gases at high pressure generating means 1, broken glass head 2, shell 3 and controller 4, an end perforate 5 of described shell 3; The most advanced and sophisticated size and the described hole 5 of broken glass head 2 are suitable; The terminal sidewall of broken glass head contacts with the inner wall sealing of shell 3, and described gases at high pressure generating means 1 is arranged on brokenly between the back seat of end and shell 3 of glass head 2, and links to each other with the controller 4 in the external world.

Embodiment two:

As shown in Figure 2, on the basis of embodiment one, the end concave of broken glass head 2 is curved, under the effect of gases at high pressure generating means 1, produces high temperature, gases at high pressure, and the edge of arcuate end is outwards pushed by radial load, forms self sealing structure; And; The terminal middle part of broken glass head 2 is provided with blind hole 6; Regulate and control high temperature, the high-pressure gas pressure of 1 output of gases at high pressure generating means through the volume of blind hole 6; The surge pressure of effective attenuation gases at high pressure is realized the self-adapting seal between gases at high pressure generating means 1, broken glass head 2, the shell 3, ensures shell 3 non-plastic deformation simultaneously; In addition; The tip of broken glass head 2 is fixed with diamond, steel alloy or cubic boron nitride, improves the toughened glass crushing success rate, even also can guarantee successfully the orcible entry rate for 15mm, 19mm thickness safety glass; And after safety glass orcible entry device used, broken glass head was most advanced and sophisticated harmless.

For making the utility model can play better technique effect, dress gases at high pressure propellant in the gases at high pressure generating means 1 utilizes high temperature, the drive of high-pressure gas of gases at high pressure propellant moment burning generation to break the purpose that glass head 2 reaches orcible entry glass.
