Description

Technical Field

[0001] This utility model relates to the field of security glass technology, and in particular to a safety explosion-proof glass with adjustable light transmission. Background Technology

[0002] Security glass is commonly used in critical facilities such as bank entrances, display cases for valuables, and doors and windows in prisons and reformatories. These areas are vulnerable to repeated attacks by groups of criminals armed with various weapons. High-strength security glass can resist penetration for a period of time, giving other devices sufficient time to react.

[0003] Bulletproof glass, a special type of safety glass, meets observation requirements while resisting explosions from a certain distance, maximizing personal safety. It features high impact resistance, good light transmission, heat resistance, and cold resistance. Currently, to improve the bulletproof performance of bulletproof glass, the common method is to increase the glass thickness and the number of interlayers. However, this results in excessively thick and heavy glass components, causing inconvenience in installation and use, and increasing production and operating costs. Because modern building designs do not consider frame systems to withstand the shockwaves of bomb blasts, building glass is often penetrated when subjected to such shockwaves. Even with bombproof glass, experiments have shown that the glass is easily damaged without a frame system, thus significantly reducing the safety and protective capabilities of buildings and secure locations.

[0004] Meanwhile, in the event of an explosion, the dimmable bulletproof glass can not only block the view but also provide better safety. Utility Model Content

[0005] This utility model discloses a safety explosion-proof glass with adjustable light transmission, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable light-transmitting safety explosion-proof glass includes a first fixed frame and a second fixed frame. A glass body is disposed inside the first and second fixed frames. The glass body is composed of a protective functional layer, an explosion-proof transition layer, a glass base layer, a dimming film layer, an adhesive layer, and a safety protection layer. The explosion-proof transition layer, glass base layer, dimming film layer, and adhesive layer are located between the protective functional layer and the safety protection layer. The explosion-proof transition layer is located at the bottom of the protective functional layer, the adhesive layer is located at the top of the safety protection layer, the glass base layer is located at the bottom of the explosion-proof transition layer, and the dimming film layer is located at the top of the adhesive layer. The protective functional layer, explosion-proof transition layer, glass base layer, and dimming film layer are all bonded together by PVB adhesive.

[0008] A snap-fit ​​assembly is provided between the first fixing frame and the second fixing frame, and the snap-fit ​​assembly is used to fix the glass body.

[0009] By placing the device in a designated position, the first and second fixing frames are separated. The glass body is then placed inside the second fixing frame and secured using a snap-fit ​​assembly. This allows for easy installation of the screw into the fixing holes. In the event of an explosion, the protective functional layer buffers the blast impact, while the explosion-proof transition layer facilitates the transition. An adhesive layer increases the adhesion between the glass panes, effectively preventing glass shards from flying. A final safety protection layer protects the other side, preventing injury. When adjusting the light transmission of the glass body, an electric current is applied to the dimming film layer, stimulating it to make the glass body opaque. This device helps prevent the impact of an explosion. Furthermore, by connecting an electric current to the dimming film layer inside the glass body, the transparency of the glass body can be controlled, preventing external strong light and other factors from igniting flammable and explosive materials. This facilitates practical application and operation.

[0010] In a preferred embodiment, the snap-fit ​​assembly includes fixing holes, screws, through slots, and inserts. The fixing holes are all located at the four corners of the top of the second fixing frame. The screws are all threaded to the four corners of the first fixing frame, and the screws are threaded to the corresponding fixing holes. The through slots are all located at the top of the second fixing frame and between two adjacent fixing holes. The inserts are all fixedly connected to the bottom of the first fixing frame and between two adjacent screws. The inserts are used in conjunction with the corresponding through slots.

[0011] Setting up a plug-in with a through slot facilitates the positioning between the first and second fixing frames, and makes it easier to install the screw inside the fixing hole.

[0012] In a preferred embodiment, the protective functional layer is made of tempered glass, the explosion-proof transition layer is made of PVB film, the glass base layer is made of PU base material, the dimming film layer is made of liquid crystal hybrid material, the adhesive layer is made of polypropylene, and the safety protection layer is made of acrylic glass.

[0013] The protective function of the protective layer is enhanced by tempered glass, the explosion-proof effect of the explosion-proof transition layer is enhanced by PVB film, the PU base material serves as the foundation of the glass body, the liquid crystal hybrid material is beneficial to enhance the dimming effect, the polypropylene material is beneficial to enhance the adhesion of the inner layer of the glass body, and the plexiglass material is beneficial to enhance the safety protection function.

[0014] In a preferred embodiment, both the bottom and top of the first and second fixing frames are provided with placement slots, and the outer center of the protective functional layer and the safety protection layer are thickened and protruded outwards, with the protrusions cooperating with the placement slots.

[0015] The placement groove combined with the protrusion facilitates the placement and fixation of the glass body between the first and second fixed frames.

[0016] In a preferred embodiment, circuit connection plates are fixedly connected to both the top and bottom of the glass body, and the circuit connection plates are electrically connected to the dimming film layer.

[0017] By setting up a circuit connection board to release voltage to stimulate the dimming film layer, the transparency of the glass body can be controlled through circuitry.

[0018] In a preferred embodiment, the inner wall of each placement groove is fixedly connected with a shock-absorbing sealing layer, and the shock-absorbing sealing layer is made of EVA material.

[0019] By incorporating EVA material, the glass body can be cushioned and shock-absorbing when it is impacted. Its softness is also beneficial for sealing the glass and effectively preventing air pressure penetration.

[0020] The adjustable light transmission safety explosion-proof glass provided by this utility model has the following advantages: The device is placed in a designated position, separating the first and second fixed frames. The glass body is then placed inside the second fixed frame and fixed using a snap-fit ​​assembly. This facilitates the installation of screws inside the fixing holes. In the event of an explosion, the protective functional layer buffers the blast impact, the explosion-proof transition layer facilitates transition, and the adhesive layer increases the adhesion between the glass panes, effectively preventing glass shards from flying. The final safety protective layer protects the other side, preventing injury to personnel. When the light transmission of the glass body needs to be adjusted, the dimming film layer is electrically energized, stimulating it to make the glass body opaque. This device helps prevent the impact of an explosion. Simultaneously, by connecting an electric current to the dimming film layer inside the glass body, the transparency of the glass body can be controlled, preventing external strong light and other factors from igniting flammable and explosive materials, thus facilitating practical application and operation.

[0027] In what scenarios is the light-transmitting, adjustable safety explosion-proof glass disclosed in this utility model primarily used?

[0028] Reference Figure 1 and Figure 2 A light-transmitting and explosion-proof safety glass includes a first fixed frame 1 and a second fixed frame 2. A glass body 4 is disposed inside the first fixed frame 1 and the second fixed frame 2. The glass body 4 is composed of a protective functional layer 401, an explosion-proof transition layer 402, a glass base layer 403, a dimming film layer 404, an adhesive layer 405 and a safety protection layer 406.

The protective functional layer 401, the explosion-proof transition layer 402, the glass base layer 403 and the dimming film layer 404 are all bonded together by PVB adhesive.

[0029] A snap-fit ​​assembly is provided between the first fixed frame 1 and the second fixed frame 2. The snap-fit ​​assembly is used to fix the glass body 4.

[0030] In this embodiment: the device is placed in a designated position, the first fixing frame 1 and the second fixing frame 2 are separated, and then the glass body 4 is placed inside the second fixing frame 2 and fixed using a snap-fit ​​assembly. This facilitates the installation of the screw 3 inside the fixing hole 6. When an explosion occurs, the protective functional layer 401 buffers the explosion impact, the explosion-proof transition layer 402 provides a transition, and the adhesive layer 405 increases the adhesion between the glass pieces, thereby effectively preventing glass from splattering. The final safety protection layer 406 protects the other side to prevent injury. When it is necessary to adjust the light transmission of the glass body 4, the dimming film layer 404 is energized, thereby stimulating the dimming film layer 404 to make the glass body 4 opaque. This device helps to prevent the impact of an explosion. At the same time, the dimming film layer 404 inside the glass body 4 can be energized by connecting electricity to control the transparency of the glass body 4, preventing external strong light and other factors from igniting flammable and explosive materials, which is beneficial for practical application and operation.

[0031] In the above technical solution, considering the existing problems, the specific operation is as follows to solve these problems.

[0032] Reference Figure 1 and Figure 4 In a preferred embodiment, the snap-fit ​​assembly includes fixing holes 6, screws 3, through slots 7, and inserts 8. The fixing holes 6 are all opened at the four corners of the top of the second fixing frame 2. The screws 3 are all threaded to the four corners of the first fixing frame 1. The screws 3 are threaded to the corresponding fixing holes 6. The through slots 7 are all opened at the top of the second fixing frame 2 and located between two adjacent fixing holes 6. The inserts 8 are all fixedly connected to the bottom of the first fixing frame 1 and located between two adjacent screws 3. The inserts 8 are used in conjunction with the corresponding through slots 7.

[0033] In this embodiment, the use of plug 8 in conjunction with through slot 7 facilitates the positioning between the first fixing frame 1 and the second fixing frame 2, and makes it easier for screw 3 to be installed inside fixing hole 6.

[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, the protective functional layer 401 is made of tempered glass, the explosion-proof transition layer 402 is made of PVB film, the glass base layer 403 is made of PU base material, the dimming film layer 404 is made of liquid crystal hybrid material, the adhesive layer 405 is made of polypropylene, and the safety protection layer 406 is made of plexiglass.

[0035] In this embodiment: tempered glass is used to enhance the protective function of the protective layer 401; PVB film material is used to enhance the explosion-proof effect of the explosion-proof transition layer 402; PU base material serves as the foundation of the glass body 4; liquid crystal hybrid material is beneficial for increasing the dimming effect; polypropylene material is beneficial for increasing the adhesion of the inner layer of the glass body 4; and plexiglass material is beneficial for increasing the safety protection function.

[0036] Reference Figure 2 and Figure 4 In a preferred embodiment, the bottom and top of the first fixing frame 1 and the second fixing frame 2 are both provided with placement grooves 9, and the outer center of the protective functional layer 401 and the safety protection layer 406 are both provided with thickened outward protrusions, which are used in conjunction with the placement grooves 9.

[0037] In this embodiment, the placement groove 9, in conjunction with the protrusion, facilitates the placement and fixing of the glass body 4 between the first fixing frame 1 and the second fixing frame 2.

[0038] Reference Figure 2 and Figure 4 In a preferred embodiment, circuit connection plates 5 are fixedly connected to the top and bottom of the glass body 4, and the circuit connection plates 5 are electrically connected to the dimming film layer 404.

[0039] In this embodiment, the circuit connection board 5 releases voltage to stimulate the dimming film layer 404, thereby achieving control over the transparency of the glass body 4 through circuit control.

[0040] Reference Figure 2 and Figure 4 In a preferred embodiment, the inner wall of the placement groove 9 is fixedly connected with a shock-absorbing sealing layer 10, and the shock-absorbing sealing layer 10 is made of EVA material.

[0041] In this embodiment, the EVA material can buffer and absorb shock when the glass body 4 is impacted. Its softness is conducive to sealing the glass and effectively preventing air pressure penetration.

[0042] Working principle: In use, place the device in the designated position, separate the first fixing frame 1 and the second fixing frame 2, then place the glass body 4 in the placement groove 9, and use the plug 8 in conjunction with the through groove 7 to position the first fixing frame 1 at the top between the second fixing frames 2. Then, use the screw 3 in conjunction with the fixing hole 6 to fix the first fixing frame 1 and the second fixing frame 2, making it easy for the screw 3 to be installed inside the fixing hole 6. When an explosion occurs, the protective functional layer 401 is used to buffer the explosion impact, the explosion-proof transition layer 402 is used for transition, and the adhesive layer 405 increases the gap between the glass. The adhesive properties effectively prevent glass from shattering. The final safety layer 406 protects the other side, preventing injury. When it is necessary to adjust the light transmission of the glass body 4, the circuit connection board 5 is used to pass electricity to the dimming film layer 404, thereby stimulating the dimming film layer 404 to make the glass body 4 opaque. This device helps to prevent the impact of an explosion. At the same time, the dimming film layer 404 inside the glass body 4 can be energized by connecting electricity, thereby controlling the transparency of the glass body 4 and preventing external strong light and other factors from igniting flammable and explosive materials. This is beneficial for practical application and operation.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
