Description

Technical Field

[0001] This utility model belongs to the field of fireproof window technology, and specifically relates to a heat-insulating fireproof window. Background Technology

[0002] In the field of building fire safety, insulated fireproof windows, as important fire-resistant partition components, are widely used in high-rise buildings, shopping malls, hospitals, office buildings and other places. Their core function is to block the spread of flames and high-temperature gases when a fire occurs, while reducing heat transfer through the heat insulation structure, thus buying time for personnel evacuation and fire rescue.

[0003] For example, Chinese patent CN215408317U discloses a steel insulated fireproof window, including a fireproof window bottom frame, an anti-spreading flame-retardant barrier mechanism fixedly connected to the inner side of the fireproof window bottom frame, a special fireproof and heat-insulating window fixedly connected to the inner side of the anti-spreading flame-retardant barrier mechanism, a fireproof window top frame fixedly connected to the upper end of the fireproof window bottom frame, and an upper layer of fireproof glass fixedly connected to the inner side of the fireproof window top frame.

[0004] While the aforementioned patent addresses the issue of traditional fireproof glass's insufficient high-temperature insulation and tendency to shatter and cause secondary injuries, it still has other shortcomings that require improvement. This patent relies solely on the integrity of the fireproof glass to block harmful gases without incorporating external gas filtration and interception structures. When a fire persists for an extended period, high temperatures cause the interlayer seals of the glass to fail, or the glass to partially crack, the harmful gases generated by the fire can spread to the outside, polluting the surrounding air and potentially posing a risk of poisoning to those who have not evacuated or to rescue personnel. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a heat-insulating and fireproof window to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A fire-resistant and heat-insulating window includes a fire-resistant window bottom frame, a fire-resistant glass hinged to one side of the fire-resistant window bottom frame, and mating grooves on both sides of the interior of the fire-resistant window bottom frame. A mating block is slidably connected inside the mating groove, and a fire-resistant purification filter element is fixedly connected to one side of the mating block. A fixing mechanism is provided on one side of the fire-resistant window bottom frame, and the mating block is fixedly connected to the mating groove through the fixing mechanism.

[0007] As a preferred technical solution, the fireproof glass includes a first low-emissivity tempered glass, a second low-emissivity tempered glass is provided on one side of the first low-emissivity tempered glass, the fireproof purification filter element is provided on one side of the second low-emissivity tempered glass, tempered wired glass is provided between the first low-emissivity tempered glass and the second low-emissivity tempered glass, a first fireproof adhesive layer is coated between the tempered wired glass and the first low-emissivity tempered glass, and a second fireproof adhesive layer is coated between the tempered wired glass and the second low-emissivity tempered glass.

[0008] As a preferred technical solution, the fireproof purification filter element includes a support mesh frame, a high-temperature resistant adsorption layer is fixedly connected to one side of the support mesh frame, a flame-retardant filter layer is fixedly connected to one side of the high-temperature resistant adsorption layer inside the support mesh frame, and a sealing edge layer is fixedly connected to the periphery of the support mesh frame.

[0009] As a preferred technical solution, a handle is fixedly connected to one side of the docking block, and the handle is also located inside the docking groove.

[0010] As a preferred technical solution, the fixing mechanism includes a positioning hole, which is opened inside the mating block. A positioning rod is inserted into the positioning hole, and a screw block is fixedly connected to one side of the positioning rod. A bidirectional screw is rotatably connected to one side of the fireproof window bottom frame, and the screw block is threadedly connected to the bidirectional screw. A torsion wheel is rotatably connected to one side of the fireproof window bottom frame near the bidirectional screw. A driving tooth cone is fixedly connected to one side of the torsion wheel, and a driven tooth cone is meshed to one side of the driving tooth cone. The driven tooth cone is fixedly connected to the bidirectional screw. A sliding groove is opened on one side of the fireproof window bottom frame, and the bidirectional screw is rotatably connected to the inside of the sliding groove. The screw block is slidably connected to the inside of the sliding groove.

[0011] In summary, the present invention has the following main advantages: First, this utility model, by installing a fireproof purification filter element on the bottom frame of a fireproof window, provides stable support for the internal structure through the supporting mesh frame of the fireproof purification filter element. The high-temperature resistant adsorption layer can specifically adsorb harmful gases such as carbon monoxide and formaldehyde generated by fire, and the flame-retardant filter layer can intercept smoke particles. Even if the fire lasts for a long time and causes the seal between the fireproof glass layers to fail or partially crack, the harmful gases must be filtered by the filter element before they can diffuse, avoiding direct pollution of the surrounding air and greatly reducing the risk of poisoning to those who have not evacuated and rescue personnel. At the same time, the sealing edge layer around the filter element can tightly fit the docking groove to prevent harmful gases from leaking from the gap between the filter element and the bottom frame, further improving the reliability of harmful gas control. Secondly, this utility model, by setting a fixed mechanism, can be operated by a single person without the need for complicated tools. Especially in scenarios where it is necessary to replace the failed filter element in time after a fire to restore the window's protective function, it can significantly shorten maintenance time.

Connecting blocks 5 are slidably connected inside the connecting grooves 4. A fireproof purification filter element 3 is fixedly connected to one side of the connecting block 5. A fixing mechanism 7 is provided on one side of the fireproof window bottom frame 1. The connecting block 5 is fixedly connected to the connecting groove 4 through the fixing mechanism 7.

[0016] refer to Figure 2The fireproof glass 2 includes a first low-emissivity tempered glass 201, a second low-emissivity tempered glass 205 on one side of the first low-emissivity tempered glass 201, a fireproof purification filter element 3 on one side of the second low-emissivity tempered glass 205, and a tempered wired glass 203 between the first low-emissivity tempered glass 201 and the second low-emissivity tempered glass 205. A first fireproof adhesive layer 202 is coated between the tempered wired glass 203 and the first low-emissivity tempered glass 201, and a second fireproof adhesive layer 204 is coated between the tempered wired glass 203 and the second low-emissivity tempered glass 205. The first low-emissivity tempered glass 201 and the second low-emissivity tempered glass 205 can reduce heat transfer and improve the heat insulation effect. The tempered wired glass 203 can prevent the glass from scattering and flying everywhere after breaking, avoiding secondary injuries. The fireproof adhesive layer enhances the sealing and fire resistance between the glass layers, making it less prone to cracking even at high temperatures.

[0017] refer to Figure 3 The fireproof purification filter element 3 includes a supporting mesh frame 301. A high-temperature resistant adsorption layer 302 is fixedly connected to one side of the inner side of the supporting mesh frame 301. A flame-retardant filter layer 303 is fixedly connected to one side of the high-temperature resistant adsorption layer 302 inside the supporting mesh frame 301. A sealing edge layer 304 is fixedly connected to the periphery of the supporting mesh frame 301. By setting the fireproof purification filter element 3, the supporting mesh frame 301 provides structural support for the filter element, preventing deformation and collapse under high temperature. The high-temperature resistant adsorption layer 302 can adsorb harmful gases such as carbon monoxide and formaldehyde. The flame-retardant filter layer 303 intercepts smoke particles. The dual purification improves the gas filtration effect. The sealing edge layer 304 fits the docking groove 4 to prevent harmful gases from leaking from the edge gaps of the filter element, further ensuring the reliability of purification. The filtered gas is discharged through the supporting mesh frame 301.

[0018] refer to Figure 1 and Figure 3 A handle 6 is fixedly connected to one side of the docking block 5, and the handle 6 is also located inside the docking groove 4. By setting the handle 6, when installing the filter element, the operator holds the handle 6 on one side of the docking block 5 and pushes the docking block 5 to slide along the docking groove 4 until the filter element is in place. When removing the filter element, the operator pulls the handle 6 in the opposite direction to drive the docking block 5 to slide out of the docking groove 4 and complete the removal of the filter element.

[0019] refer to Figure 4-5The fixing mechanism 7 includes a positioning hole 701, which is located inside the mating block 5. A positioning rod 702 is inserted into the positioning hole 701. A screw block 704 is fixedly connected to one side of the positioning rod 702. A bidirectional screw 703 is rotatably connected to one side of the fireproof window bottom frame 1. The screw block 704 is threaded onto the bidirectional screw 703. A torsion wheel 705 is rotatably connected to one side of the fireproof window bottom frame 1 near the bidirectional screw 703. A driving tooth cone 706 is fixedly connected to one side of the torsion wheel 705. A driven tooth cone 707 is meshed with one side of the driving tooth cone 706. The driven tooth cone 707 is fixedly connected to the bidirectional screw 703. A sliding groove 8 is provided on one side of the fireproof window bottom frame 1, and the bidirectional screw 703 is rotatably connected inside the sliding groove 8. The screw block 704 is slidably connected inside the slide groove 8. By setting the fixing mechanism 7, the torsion wheel 705 on the bottom frame 1 of the fireproof window is rotated. The torsion wheel 705 drives the active tooth cone 706 on one side to rotate. The active tooth cone 706 meshes with and drives the driven tooth cone 707. The driven tooth cone 707 drives the bidirectional screw 703 to rotate in the slide groove 8. When the bidirectional screw 703 rotates, the screw block 704 connected by threads slides along the slide groove 8, driving the positioning rod 702 to move towards the docking block 5 until the positioning rod 702 is inserted into the positioning hole 701 inside the docking block 5, thus completing the fixing. When the fixing is released, the torsion wheel 705 is rotated in the opposite direction, and the screw block 704 drives the positioning rod 702 to come out of the positioning hole 701. Without the need for complicated tools, a single person can complete the fixing and releasing operations, which greatly shortens the maintenance time and is suitable for the scenario of quickly replacing the filter element after a fire.

[0020] Operating principle and advantages: A first fireproof adhesive layer 202 is coated between the first low-emissivity tempered glass 201 and the tempered wired glass 203, and a second fireproof adhesive layer 204 is coated between the tempered wired glass 203 and the second low-emissivity tempered glass 205, forming a five-layer composite structure. The low-emissivity tempered glass reduces heat transfer and improves heat insulation. The tempered wired glass 203 prevents the glass from scattering and causing secondary injuries after breakage. The fireproof adhesive layer enhances the sealing and fire resistance between the glass layers, making it less prone to cracking even at high temperatures. The high-temperature resistant adsorption layer 302 can adsorb harmful gases such as carbon monoxide and formaldehyde. The flame-retardant filter layer 303 can intercept smoke particles. This dual purification enhances the gas filtration effect. The sealing edge layer 304 fits the mating groove 4 to prevent harmful gases from leaking from the edge gaps. When installing the filter element, the operator holds the handle 6 on one side of the mating block 5 and pushes... The movable docking block 5 slides along the docking grooves 4 on both sides inside the bottom frame until the filter element is in place against the inner side of the bottom frame. The sliding cooperation between the docking groove 4 and the docking block 5 provides a precise installation guide for the filter element, avoiding installation misalignment. Finally, the filter element is fixed by the fixing mechanism 7. The torsion wheel 705 on the bottom frame is rotated. The torsion wheel 705 drives the active toothed cone 706 on one side to rotate. The active toothed cone 706 meshes with and drives the driven toothed cone 707. The driven toothed cone 707 drives the bidirectional screw 703 to rotate in the slide groove 8. When the bidirectional screw 703 rotates, the threaded block 704 slides along the slide groove 8, driving the positioning rod 702 to move towards the docking block 5 until the positioning rod 702 is inserted into the positioning hole 701 inside the docking block 5, completing the fixing. Without the need for complicated tools, a single person can complete the fixing and unfixing operation, greatly shortening the maintenance time and adapting to the scenario of quickly replacing the filter element after a fire.
