Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass windows, and in particular to a tempered glass window with an emergency breaking function. Background Art

[0002] In modern architecture, automobile manufacturing, electronic products and daily home use, glass, as an important transparent material, is widely used in windows, doors, display cabinets, screens and other fields. Traditional tempered glass is widely used in building doors and windows and other fields due to its high strength and strong impact resistance. However, after breaking, it will shatter into blunt-angled particles. Although this reduces the risk of cuts, it may still hinder emergency escape or rescue. In the existing technology, some tempered glass achieves directional breakage through interlayer or local treatment, but there are problems with complex structure, high cost or insufficient reliability. Tempered glass, also known as safety glass, is made by heating ordinary glass to near its softening point and then rapidly cooling it. This process causes compressive stress on the surface of the tempered glass, while maintaining tensile stress inside, thereby significantly improving its impact resistance and heat resistance. The bending strength of tempered glass is usually 3-5 times that of ordinary glass, so it is widely used in various occasions with high safety requirements. When tempered glass is hit or pressed by heavy objects, if the impact force exceeds its compressive strength, the glass will break. Although tempered glass is strong, when it breaks, its fragments often appear sharp and flake-like, which can easily cause personal injury. The stress layer on the surface of tempered glass makes it extremely impact-resistant, and ordinary tools (such as fire extinguishers and hammers) are difficult to break in a short time, delaying escape time.

[0003] When using tempered glass windows, if an emergency occurs indoors and you need to escape through the window, you need to quickly hammer the tempered glass to break it. If the broken glass is not restricted, the fragments will fly everywhere during the shattering process, which may cause harm to the person breaking the window. Summary of the Invention

[0004] The present invention relates to a tempered glass window with an emergency breaking function. When a breaker hammer strikes the tempered glass, a transparent protective plate and a protective strip cooperate to block and limit flying fragments. The transparent protective plate is usually arranged directly in front of the operator. At the same time, a PVB film also adheres to the broken fragments. After the tempered glass is shattered, the PVB film layer bonds the fragments into a mesh structure. Even if the tempered glass is broken, the fragments still adhere to the PVB film to reduce the amount of flying, and physically block the glass fragments from flying outward. In particular, it can intercept large or high-speed fragments to prevent them from directly impacting the human face, thereby effectively protecting the surrounding people.

[0005] In a first aspect, the present invention provides a tempered glass window with an emergency break function, comprising: an aluminum outer frame; four threaded grooves formed at the lower end of a front side wall of the aluminum outer frame; a glass outer frame slidably mounted in the middle of the aluminum outer frame, and threaded holes penetrating the glass outer frame are formed at the four corners; two threaded grooves are formed at each end of the front side wall of the glass outer frame; An inner frame is slidably mounted in the middle of the glass outer frame; a glass groove is provided on the inner side wall of the middle portion of the inner frame, and mutually symmetrical tempered glasses are installed in the glass groove, and a glass adhesive layer is applied on the side walls of the two tempered glasses at opposite ends; PVB films are respectively pasted on the side walls of the two pieces of tempered glass facing away from one end, a transparent protective plate is fixedly installed on the front side of the glass outer frame, and screws are inserted through the four corners of the transparent protective plate; a penetrating center crushing circle is opened in the middle of the transparent protective plate; and symmetrical protective strips are fixedly installed on the back side of the transparent protective plate.

[0006] Furthermore, mutually symmetrical track anti-slip grooves are provided on the inner side wall of the aluminum outer frame, and an electric roller blind is fixedly installed on the rear end of the aluminum outer frame.

[0007] Furthermore, an electric screen is installed in the middle of the electric roller shutter window, and a tool receiving box is fixedly installed on the front side wall of the lower end of the aluminum outer frame.

[0008] Furthermore, side panels are fixedly installed on both sides of the tool holding box, and screws are inserted through both ends of the side panels.

[0009] Furthermore, a multi-head screwdriver is placed inside the tool receiving box, and a breaker hammer is placed inside the tool receiving box.

[0010] Furthermore, track anti-slip strips are fixedly mounted on the side walls at the upper and lower ends of the glass outer frame, and an inner frame groove is provided on the inner side wall in the middle of the glass outer frame.

[0011] Furthermore, inner sliding grooves parallel to each other are respectively provided at the upper and lower ends of the inner frame groove, positioning limiting plates are respectively installed at both ends of the inner frame groove, and screws are respectively rotatably inserted through the two ends of the positioning limiting plates.

[0012] Furthermore, inner frame slide bars parallel to each other are fixedly mounted on both side walls of the outer end of the inner frame, and a handle connecting rod is fixedly mounted on the right end of the inner frame.

[0013] The present invention provides a tempered glass window with an emergency breaking function, which has the following beneficial effects: When the tempered glass window of the present invention is in use, when a breaker hammer hits the tempered glass, the transparent protective plate and the protective strip cooperate to block and limit the flying fragments. The transparent protective plate is usually set in front of the operator. At the same time, the PVB film will also adhere to the broken fragments. After the tempered glass is shattered, the PVB film layer will bond the fragments into a mesh structure. Even if the tempered glass is broken, the fragments will still adhere to the PVB film to reduce the amount of flying, and physically block the glass fragments from flying outward. It can especially intercept large or high-speed fragments to prevent them from directly impacting the human face, thereby effectively protecting the surrounding people.

[0014] In addition, when an emergency accident occurs indoors, grab the breaker hammer and aim it at the center breaking circle, then use the breaker hammer to hammer and break the tempered glass behind the center breaking circle, which can quickly disintegrate the overall structure of the tempered glass. 1-2 hammerings can form a passable gap. The broken glass is blocked by transparent protective plates and protective strips to prevent fragments from splashing into the room, protecting the window breaker and surrounding people, and preventing broken glass from splashing everywhere and injuring surrounding people, thereby effectively protecting the person who broke the glass, and then people can escape from the gap in the tempered glass.

[0015] In addition, electric screens are usually made of high-strength fiber or metal materials. Electric screens can block external flying insects. The tight mesh design (usually ≤18 meshes) can effectively block mosquitoes, moths, etc., while maintaining air circulation. External flying insects cannot enter the room. When the electric screen is retracted, it is completely hidden in the electric roller shutter screen to maintain the transparency of the window. The strength of tempered glass is 4-5 times that of ordinary glass. It can withstand greater impact force and prevent tempered glass from being easily broken by external birds and other impacts.

[0016] By using two positioning and limiting plates to temporarily fix and limit the inner frame, when the indoor passage is blocked and difficult to clear and an unexpected situation requires escape, use a multi-head screwdriver to remove the screws on the right-end positioning and limiting plate, then slide the inner frame to the right, slide the inner frame out of the inner frame slot and remove it, and then crack and remove the screws on the transparent protective plate. At this time, rescue the indoor people from the glass outer frame at this location without breaking the tempered glass. Traditional escape requires breaking the glass, which is time-consuming and may delay the rescue due to the high strength of the glass (such as double-layer laminated tempered glass). This design is more efficient by dismantling the structural parts to directly open the passage. The tempered glass and outer frame remain intact, reducing the subsequent replacement cost. Broken tempered glass may injure trapped people or rescuers, but this method does not have this hidden danger. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1: Please refer to Figures 1 to 9 : The present invention proposes a tempered glass window with an emergency breaking function, comprising: an aluminum outer frame 1; four threaded grooves are provided at the lower end of the front side wall of the aluminum outer frame 1; a glass outer frame 2 is slidably installed in the middle of the aluminum outer frame 1, and threaded holes are respectively provided at the four corners of the glass outer frame 2; two threaded grooves are respectively provided at both ends of the front side wall of the glass outer frame 2; an inner frame 3 is slidably installed in the middle of the glass outer frame 2; a transparent protective plate 4 is fixedly installed on the front side of the glass outer frame 2, and external sunlight passes through the transparent protective plate 4 and shines into the room, and screws are respectively inserted at the four corners of the transparent protective plate 4; the screws on the transparent protective plate 4 are turned and inserted into the threaded grooves of the glass outer frame 2 to fix and restrict the transparent protective plate 4. When the transparent protective plate 4 is touched, it will not move, so as to prevent the transparent protective plate 4 from falling when touched and being unable to block the broken glass. A central breaking circle 401 is provided through the transparent protective plate 4; symmetrical protective strips 402 are fixedly installed on the rear side of the transparent protective plate 4, and the rear side of the protective strips 402 is attached to the side wall of the front tempered glass 304. When an emergency accident occurs indoors (for example, fire or flood, etc.), grab the breaker hammer 107 and aim it at the central breaking circle 401, and then use the breaker hammer 107 to hammer and break the tempered glass 304 behind the central breaking circle 401. The broken glass is blocked by the transparent protective plate 4 and the protective strip 402, and the broken glass will not splash everywhere and injure the surrounding people, thereby effectively protecting the people who break the glass. Then pull the transparent protective plate 4 forward and tear it off, or use the breaker hammer 107 to hammer the two screws at the upper end of the transparent protective plate 4 to break it. At this time, flip the upper end of the transparent protective plate 4 downward, and then people can escape from the broken part of the tempered glass 304.

[0022] Among them, the inner wall of the aluminum outer frame 1 is provided with mutually symmetrical track anti-slip grooves 101, the rear end of the aluminum outer frame 1 is fixedly installed with an electric roller screen 102, and the middle part of the electric roller screen 102 is installed with an electric screen 103. The electric screen 103 is usually made of high-strength fiber or metal material, which is insect-proof and has shear resistance. The electric screen 103 can block external flying insects and prevent external flying insects from entering the room. When the electric screen 103 is retracted, it is completely hidden in the electric roller screen 102 to maintain the transparency of the window. A tool receiving box 104 is fixedly installed on the front side wall of the lower end of the aluminum outer frame 1, and side panels 105 are respectively fixedly installed on both sides of the tool receiving box 104, and screws are respectively inserted at both ends of the side panels 105 to set the tool receiving box 104 At the front lower part of the glass outer frame 2, it is convenient for people to take out the multi-head screwdriver 106 and the breaker hammer 107 in the tool receiving box 104, turn the screws on the side panel 105 and insert them into the threaded groove on the front side of the aluminum outer frame 1, and fix the side panel 105 and the tool receiving box 104. When the tool receiving box 104 is touched, it will not fall off. In this way, the tool receiving box 104 can stably carry the multi-head screwdriver 106 and the breaker hammer 107. The multi-head screwdriver 106 is placed inside the tool receiving box 104, and all screws can be removed using the multi-head screwdriver 106. A breaker hammer 107 is placed inside the tool receiving box 104. The right end of the breaker hammer 107 is a conical structure, and the breaker hammer 107 can easily knock and break the tempered glass 304.

[0023] When the glass outer frame 2 slides left and right, the track anti-slip strips 201 are restricted by the track anti-slip grooves 101, and the glass outer frame 2 can only slide left and right, preventing the glass outer frame 2 from tilting when sliding left and right. An inner frame groove 202 is provided on the inner side wall in the middle of the glass outer frame 2. First, the left end positioning and limiting plate 204 is fixedly installed at the left end of the inner frame groove 202 by screws, and then the inner frame 3 is slidably installed in the inner frame groove 202. When the inner frame 3 and the side wall of the left end positioning and limiting plate 204 are attached, the inner frame 3 will stop moving, and then the right end positioning and limiting plate 204 is fixedly installed at the right end of the inner frame groove 202 by screws. At this time, the side wall of the right end positioning and limiting plate 204 is attached to the side wall of the inner frame 3, and the inner frame 3 is temporarily fixed with two positioning and limiting plates 204. When the door frame 3 is in the open position, the occupant 204 is tightened and the door frame 3 is tightened, and the occupant 204 is tightened and the door frame 3 is tightened.

[0024] Among them, inner frame slide bars 301 parallel to each other are fixedly installed on the two side walls of the outer end of the inner frame 3, and the inner frame slide bars 301 are slidably installed in the inner slide grooves 203. When the inner frame 3 slides left and right, the inner frame slide bars 301 are restricted by the inner slide grooves 203, and the inner frame 3 can only slide left and right to prevent the inner frame 3 from tilting when sliding left and right. A handle connecting rod 302 is fixedly installed on the right end of the inner frame 3. Grasping the handle connecting rod 302 facilitates moving the inner frame 3 left and right. A glass groove 303 is opened on the inner side wall in the middle of the inner frame 3, and mutually symmetrical tempered glasses 304 are installed in the glass grooves 303. The strength of the tempered glass 304 The strength is 4-5 times that of ordinary glass and can withstand greater impact. The side walls of the two tempered glasses 304 facing each other are coated with a glass adhesive layer 305. When the tempered glass 304 breaks, it will form small obtuse-angled particles, but the glass adhesive layer 305 can adhere to the fragments to prevent flying and hurting people. It is especially suitable for high-rise buildings. The glass adhesive layer 305 (especially PVB) can effectively block sound wave vibrations and reduce noise transmission. The side walls of the two tempered glasses 304 facing away from each other are respectively adhered with PVB films 306. The viscoelasticity of PVB film 306 can absorb impact energy. Even if the glass shatters, the fragments will still adhere to the film to prevent flying and hurting people.

[0025] Example 2, based on Example 1, Figure 1 and Figure 9 As shown, a transparent protective plate 4 is fixedly installed on the front side of the glass outer frame 2, and penetrating screws are respectively inserted at the four corners of the transparent protective plate 4. The screws on the transparent protective plate 4 are removed, and then the upper and lower ends of the transparent protective plate 4 are fixed and glued to the two ends of the glass outer frame 2 respectively to firmly restrict the transparent protective plate 4. In this way, the transparent protective plate 4 will not fall off the glass outer frame 2 when touched, avoiding the screws from loosening due to long-term use and failing to stabilize the transparent protective plate 4, while also saving parts costs.

[0026] The working principle of this embodiment: When in use, the electric screen 103 is usually made of high-strength fiber or metal material, which is insect-proof and has shear resistance. The electric screen 103 can block flying insects from the outside and prevent flying insects from entering the room. When the electric screen 103 is retracted, it is completely hidden in the electric roller blind 102 to maintain the transparency of the window. First, the left end positioning and limiting plate 204 is fixed to the left end of the inner frame groove 202 by screws, and then the inner frame 3 is slid to the left in the inner frame groove 202. When the inner frame 3 and the left end positioning and limiting plate 204 are fixed, the inner frame 3 is slid to the left in the inner frame groove 202. 4, the inner frame 3 will stop moving, and then the right end positioning and limiting plate 204 is fixed to the right end of the inner frame groove 202 by screws. At this time, the side wall of the right end positioning and limiting plate 204 is in contact with the side wall of the inner frame 3, and the two positioning and limiting plates 204 are used to temporarily fix and limit the inner frame 3. When the indoor passage is blocked and difficult to clean, an unexpected situation occurs and escape is required. Use a multi-head screwdriver 106 to remove the screws on the right end positioning and limiting plate 204, then slide the inner frame 3 to the right, and remove the inner frame 3 from the inner frame groove 202. The glass 304 can be used again after the accident is resolved. When an emergency occurs indoors (for example, a fire or flood), the breaker hammer 107 is grasped and aimed at the center breaking circle 401. Then, the breaker hammer 107 is used to hammer and break the tempered glass 304 behind the center breaking circle 401. The broken glass is supported by the transparent protective plate 4 and the tempered glass 304. The protective strip 402 blocks the broken glass from splashing around and injuring people around, thus effectively protecting the people who break the glass. At the same time, the viscoelasticity of the PVB film 306 can absorb the impact energy. Even if the glass breaks, the fragments will still adhere to the film to avoid splashing and injuring people. Then, the transparent protective plate 4 can be pulled forward and torn off, or the two screws at the upper end of the transparent protective plate 4 can be hammered with a breaker hammer 107 to break it. At this time, the upper end of the transparent protective plate 4 is flipped downward, and then people can escape from the broken part of the tempered glass 304.
