Technical Field
[0001] This utility model specifically relates to the field of aluminum alloy door and window technology, and more specifically to an aluminum alloy door and window with a heat insulation and fireproof structure. Background Technology
[0002] Aluminum alloy doors and windows (especially thermally broken aluminum) are a cost-effective choice, balancing durability, functionality, and aesthetics, and suitable for the long-term use needs of most families. When choosing aluminum alloy doors and windows, it is necessary to comprehensively consider the building function, climate conditions, budget, and industry standards. Prioritize products with reports from CNAS-certified testing institutions to ensure that performance meets standards.
[0003] However, in practice, aluminum alloys (especially thermally broken aluminum) need to balance fire safety with good thermal insulation through process optimization, making them suitable for building scenarios that require both safety and energy conservation. This is closely related to their material properties and processing technology, and needs to be analyzed in conjunction with specific scenarios (such as doors, windows, components, etc.). Chinese Utility Model Publication No. CN202321752021.X discloses an aluminum alloy door and window with a heat-insulating and fireproof structure, including an aluminum alloy door and window body, a fireproof frame fixedly installed on the front edge of the aluminum alloy door and window body, a fireproof plate connected to the side hinge of the fireproof frame, a fireproof box fixedly installed on the front of the fireproof plate; a sealing plug, the sealing plug being movably installed on the upper inner wall of the side of the front of the fireproof box, and sealing mechanisms being provided on both sides of the upper surface of the fireproof box; a positioning cylinder, the positioning cylinder being fixedly installed in the middle of the outer wall of the side of the fireproof frame, a square seat being movably connected to the inner wall of the positioning cylinder, a pull rod being fixedly connected to the outer wall of the side of the square seat, and a clamping plate being fixedly provided on the outer wall of the side of the pull rod. The aforementioned aluminum alloy door and window with a heat-insulating and fire-resistant structure works by filling a fireproof box with water. In the event of a fire, the heat generated is transferred to the water. Simultaneously, the water vapor generated by the heating of the water pushes open the sealing mechanism to cool it down. However, after a fire, the longer the time, the more water is consumed by evaporation. The excessively high temperature of the flames also accelerates the evaporation of water, greatly reducing the heat insulation effect. To address this, we provide a heat-insulating and fire-resistant aluminum alloy door and window. A roller shutter is provided at the upper end of the door frame. The roller shutter contains a magnesium oxychloride fireproof board to prevent further spread of flames. The inner box inside the middle section of the double-frame door is filled with a silicone oil-based heat-insulating liquid to reduce heat transfer. Utility Model Content
[0004] The purpose of this utility model is to provide an aluminum alloy door and window with a heat-insulating and fire-resistant structure. A roller shutter door is provided on the upper side of the door frame, which can be rolled up to store a magnesium oxychloride fireproof board. In the event of a fire, a handle can be pulled down and locked into a locking groove at the lower end of the door frame, allowing the magnesium oxychloride fireproof board to provide a certain degree of fire protection after being fixed. After a fire drill, a push rod is used to push the locking device to loosen the magnesium oxychloride fireproof board. Electricity is used to start the gears of the drive motor, which pulls the drive chain, rolling up and storing the magnesium oxychloride fireproof board inside the roller shutter door for future use. An inner box is located in the middle section of the double-frame door. Silicone oil-based heat-insulating liquid is fed into the inner box through a feed port. In the event of a fire, the handle can be used to open the double-frame door for escape and rescue, increasing the chances of survival. The structure is simple and easy to operate, thus solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An aluminum alloy door and window with a heat-insulating and fire-resistant structure includes a door frame, a double-frame door on one side of the door frame, a snap-fit groove on the lower inner wall of the door frame, a through groove on the other side of the lower inside of the door frame, the through groove including a push rod, one end of the push rod being movably connected to the snap-fit groove, and a roller shutter door on the upper side of the door frame. The double-frame door has a set of door frames on one side, and an inner box is opened in the middle section of the double-frame door. The inner box contains silicone oil-based heat insulation liquid, and a handle is provided on the outer wall of the middle section of the double-frame door.
[0006] As a further technical solution of this utility model, both ends of the snap-fit groove are provided with rotating rods, the rotating rods are movably connected to snap-fit devices, and a push plate is provided on one side of the snap-fit device. The push plate is connected to a spring that is inclined and fits against the snap-fit groove.
[0007] As a further technical solution of this utility model, a drive motor is provided on one side of the upper end of the roller shutter door. The drive motor is fixedly connected to the roller shutter door by bolts. A gear is connected to one end of the drive motor. A drive chain is provided on the gear. A chain groove is opened on the roller shutter door at one end of the gear. A rotating roller is provided in the middle of the inner walls on both sides of the roller shutter door. The rotating roller is fixedly connected to the roller shutter door. A drive gear is movably connected at one end of the rotating roller. The drive gear and the gear are movably connected by meshing through the drive chain. The rotating roller includes a T-slot and a locking block. The locking block is locked into the T-slot. A magnesium oxychloride fireproof board is provided in the middle section of one side of the locking block. The magnesium oxychloride fireproof board extending from the T-slot is attached to the outer wall of the rotating roller.
[0008] As a further technical solution of this utility model, the snap-fit block is fixedly connected to one end of the magnesium oxychloride fireproof board by bolts, a handle is provided on one side of the lower end of the magnesium oxychloride fireproof board, a snap-fit plate is provided on the other end of the magnesium oxychloride fireproof board, and the length and width of the magnesium oxychloride fireproof board are greater than the length and width of the double frame door.
[0009] As a further technical solution of this utility model, the door frame is disconnected from the snap-fit device and the snap-fit plate at one end of the snap-fit groove by a push rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, when in use, features a roller shutter door at the top of the door frame. A magnesium oxychloride fireproof board is rolled up and stored on the rotating roller of the roller shutter door. A connecting groove is provided on the rotating roller, and the magnesium oxychloride fireproof board is secured inside the rotating roller by a snap-fit block within the connecting groove. When not in use, the magnesium oxychloride fireproof board is stored in the roller shutter door, saving space. A handle on one side of the lower end of the magnesium oxychloride fireproof board allows it to be pulled down. After being pulled down, a snap-fit plate at the bottom of the magnesium oxychloride fireproof board enters the snap-fit groove. As the snap-fit plate enters the snap-fit groove, the snap-fit device in the snap-fit groove deflects under the action of the rotating rod, causing the spring tilted behind the push plate to compress. After the snap-fit plate is fully inside the snap-fit groove, the spring pops out, causing the push plate to rotate the snap-fit device, which then snaps the snap-fit plate, securing the magnesium oxychloride fireproof board. In the event of a fire, this prevents the flames from burning on the magnesium oxychloride fireproof board and keeps the flames out.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-12 This utility model embodiment provides an aluminum alloy door and window with a heat insulation and fireproof structure, including a door frame 1, a double frame door 2 on one side of the door frame 1, a snap-fit groove 5 on the lower inner wall of the door frame 1, a through groove 4 on the other side of the lower end of the door frame 1, the through groove 4 including a push rod 41, one end of the push rod 41 being movably connected to the snap-fit groove 5, and a roller shutter door 3 on one side of the upper end of the door frame 1. The double-frame door 2 has a set of door frames 22 on one side, and an inner box 23 is opened in the middle section of the double-frame door 2. The inner box 23 contains silicone oil-based heat insulation liquid, and a handle 21 is provided on the outer wall of the middle section of the double-frame door 2.
[0027] By adopting the above technical solution, after the production of the double-frame door 2, the silicone oil-based heat insulation liquid is injected into the inner box 24 from the feed port 22. When the double-frame door 2 is closed in the event of a fire, the silicone oil-based heat insulation liquid in the inner box 24 reduces the temperature transmission during the fire, thereby reducing the heat of the handle 21 and increasing the chance of escape.
[0028] In this embodiment of the utility model, both ends of the snap-fit groove 5 are provided with rotating rods 52, and the rotating rods 52 are movably connected to snap-fit devices 51. A push plate 53 is provided on one side of the snap-fit device 51, and the push plate 53 is connected to a spring 54 that is inclined and fits against the snap-fit groove 5.
[0029] By adopting the above technical solution, after the magnesium oxychloride fireproof board 31 is pulled down, the snap-fit device 51 flips in the rotating rod 52, leans against the push plate 53 and the spring 54 is compressed. After the magnesium oxychloride fireproof board 31 is fully inserted, the snap-fit device 51 snaps into the magnesium oxychloride fireproof board 31 and fixes it after the spring 54 is activated. The flame will be blocked by the magnesium oxychloride fireproof board 31 and will not enter the double frame door 2.
[0030] In this embodiment of the utility model, a drive motor 33 is provided on one side of the upper end of the roller shutter door 3. The drive motor 33 is fixedly connected to the roller shutter door 3 by bolts. A gear 39 is connected to one end of the drive motor 33. A drive chain 34 is provided on the gear 39. A chain groove 37 is provided on the roller shutter door 3 at one end of the gear 34. A rotating roller 36 is provided in the middle of the inner walls on both sides of the roller shutter door 3. The rotating roller 36 is fixedly connected to the roller shutter door 3. A drive gear 35 is provided at one end of the rotating roller 36. The drive gear 35 and the gear 39 are movably connected by meshing through the drive chain 34. The rotating roller 36 includes a T-shaped groove 362 and a snap-fit block 361. The snap-fit block 361 snaps into the T-shaped groove 362. A magnesium oxychloride fireproof board 31 is provided in the middle section of one side of the snap-fit block 361, and the magnesium oxychloride fireproof board 31 extending from the T-shaped groove 362 is attached to the outer wall of the rotating roller 36.
[0031] By adopting the above technical solution, the magnesium oxychloride fireproof board 31 on the rotating roller 36 can be rolled up and stored when not in use. At the same time, after the fire drill, the magnesium oxychloride fireproof board 31 is released and the transmission motor 33 is driven by electricity to drive the transmission gear chain 34. Driven by the operation of the transmission gear chain 34, the magnesium oxychloride fireproof board 31 is rolled up and stored in the roller shutter door for reuse next time.
[0032] In this embodiment of the utility model, the rotating roller 36 is fixedly connected to one end of the magnesium oxychloride fireproof board 31, a handle 38 is provided on one side of the lower end of the magnesium oxychloride fireproof board 31, and a snap-fit plate 32 is provided on the other end of the magnesium oxychloride fireproof board 31. The length and width of the magnesium oxychloride fireproof board 31 are greater than the length and width of the double frame door 2.
[0033] By adopting the above technical solution, after the magnesium oxychloride fireproof board 31 is pulled down by the handle 38 on the magnesium oxychloride fireproof board 31, the snap-fit plate 51 is snapped and fixed in the snap-fit groove 5. When the length and width of the magnesium oxychloride fireproof board 31 are greater than those of the double frame door 2, it can more effectively block the further spread of flames.
[0034] In this embodiment of the utility model, the door frame 1 is disconnected from the connection between the snap fastener 51 and the snap fastener plate 32 at one end of the snap fastener groove 5 by the push rod 41.
[0035] By adopting the above technical solution, after pushing the push rod 41, one end of the locking groove 5 extends out, causing the locking device 51 to reverse and the locking plate 32 to loosen. After the magnesium oxychloride fireproof board 31 is no longer fixed, it can be rolled up and stored.
[0036] The working principle of this utility model is as follows: When used in the event of a fire or during a fire drill, a roller shutter door 3 is provided at the upper end of the door frame 1. A magnesium oxychloride fireproof board 31 is rolled up and stored on the rotating roller 36 of the roller shutter door 3. A T-slot 362 is provided on the rotating roller 36, and the magnesium oxychloride fireproof board 31 is secured inside the rotating roller 36 by a snap-fit block 361 within the T-slot 362. The magnesium oxychloride fireproof board 31 is fixedly connected to the middle section of the snap-fit block 361 by bolts. A handle 38 is provided on one side of the lower end of the magnesium oxychloride fireproof board 31 to pull it down. After pulling down, the snap-fit plate 32 at the bottom of the magnesium oxychloride fireproof board 31 enters the snap-fit groove 5, so that when the snap-fit plate 32 enters the snap-fit groove 5... The snap-fit device 51 deflects under the action of the rotating rod 52, which drives the spring 54 of the push plate 53 to compress. After the snap-fit plate 32 is fully inserted into the snap-fit groove 5, the spring 54 pops out and drives the push plate 53 to rotate the snap-fit device 51. The snap-fit device 51 then snaps into the snap-fit plate 32 and fixes the magnesium oxychloride fireproof board 31. In the event of a fire, the flame will stop burning on the magnesium oxychloride fireproof board 31 and will block the flame from the outside. At the same time, the double frame door 2 is closed. An inner box 23 is opened in the middle section of the double frame door 2. After the double frame door 2 is produced, silicone oil-based heat insulation liquid is introduced into the inner box 23. The silicone oil-based heat insulation liquid can isolate the external heat and reduce the heat of the handle 21, so that it can be opened quickly when needed. After the fire drill is completed, the latch 51 is engaged with the latch plate 32. A push rod 41 is attached to the slot 4 on one side of the lower end of the door frame 2 and pushed. The other end of the push rod 41 is inserted into the inner wall of the latch slot 5. The latch 51 deflects on the rotating rod 52, and the latch 51 releases the latch plate 32, thus the magnesium oxychloride fireproof board 31 is no longer engaged. Inside the roller shutter door 3, a rotating roller 36 is located in the middle, with a movably connected gear 39 at one end. A transmission gear chain 34 meshes with the gear 39. A toothed chain groove 37 is provided on the door frame at position 34, and a transmission gear 34 connected to a rotating roller 36 is meshed and movably connected to the other end of the transmission toothed chain 34. The gear 39 of the transmission motor 33 is started to rotate by electricity, and then the transmission toothed chain 34 is pulled. Under the drive of the transmission toothed chain 34, the power is continuously transmitted to the gear 39 at one end of the rotating roller 36, so that the magnesium oxychloride fireproof board 31 can be rolled up for the next use. The rotating roller 36 can play a role in storing the magnesium oxychloride fireproof board 31. The structure is simple and the operation is very convenient.
