Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to an aluminum alloy door and window structure that blocks thermal bridges. Background Technology

[0002] Aluminum alloy door and window structures are a widely used form of door and window construction in modern buildings. They are mainly used for separating indoor and outdoor spaces and for ventilation and lighting functions. With the high strength, good corrosion resistance, and beautiful and durable characteristics of aluminum alloy, they play an important role in various building projects, whether residential, commercial or public facilities, and become a key component connecting the indoor and outdoor environments.

[0003] Traditional aluminum alloy door and window structures mainly consist of aluminum alloy frames, glass, and sealing strips. In use, the aluminum alloy frame acts as a supporting structure, bearing the glass and fixing it to the pre-drilled opening in the building wall. The glass allows for lighting and visibility, while the sealing strips provide a certain degree of sealing and buffering. However, this traditional structure has significant drawbacks, particularly in its poor temperature insulation. Because aluminum alloy is a good conductor of heat, when there is a large temperature difference between indoors and outdoors, heat is rapidly conducted through the aluminum alloy frame, leading to heat loss or excessive heat entering the room, failing to effectively insulate against temperature differences. Current technology uses a single nylon spacer in the aluminum alloy frame to block thermal bridges. In practical use, when there is a temperature difference between indoors and outdoors, it is expected that the nylon spacer can prevent heat conduction through the aluminum alloy frame. However, this improved structure still suffers from poor thermal insulation performance because the thermal resistance of a single nylon spacer is limited. Over time and with environmental changes, the nylon spacer will age and deform, leading to a decrease in its fit with the aluminum alloy frame and the appearance of gaps. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aluminum alloy door and window structure that blocks thermal bridges, aiming to improve the problem of limited thermal resistance and poor thermal insulation performance of a single nylon strip in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy door and window structure for blocking thermal bridges, comprising an inner frame and an outer frame, wherein a heat insulation mechanism is provided between adjacent parts of the inner frame and the outer frame, and a connecting mechanism is provided between adjacent parts of the inner frame and the outer frame. The inner frame and the connecting mechanism are each provided with a heat insulation plate 1 on their upper and lower sides. The inner frame and the outer frame are each provided with a heat insulation plate 2 on their left and right sides. The upper and lower sides of the adjacent ends of the inner frame and the outer frame are each provided with a mounting groove 1. The left and right sides of the adjacent ends of the inner frame and the outer frame are each provided with a mounting groove 2. The two heat insulation plates 1 and 2 are slidably connected to the corresponding mounting grooves 1 and 2, respectively. The four corners of the outer walls of the inner frame and the outer frame are each provided with a reserved opening. The outer wall of the adjacent side of the inner frame and the outer frame is provided with an outer heat insulation strip. The inner wall of the inner frame is provided with an inner heat insulation strip. The interior of the inner frame is provided with a protective component. The four corners of the outer walls of the inner frame and the outer frame are each provided with a dustproof component.

[0006] Through the above technical solution: the inner frame and the outer frame work together through the heat insulation mechanism and the connecting mechanism. Heat insulation plate one and heat insulation plate two slide into the corresponding mounting groove one and mounting groove two respectively, initially fixing the inner and outer frames, and blocking heat transfer between the inner and outer frames by means of their heat insulation performance. The outer heat insulation strip and the inner heat insulation strip are placed on the outer wall and inner wall of the adjacent sides of the inner and outer frames respectively, further enhancing the heat insulation effect. The reserved opening is used to install the dustproof component. The protective component is located inside the inner frame, which plays a role in protection and realizing the normal use function of the door and window. The dustproof component prevents dust from entering from the corner gaps of the door and window, maintaining the internal cleanliness.

[0007] As a further description of the above technical solution: The connecting mechanism includes multiple threaded sleeves. Multiple mounting holes are provided on the left and right sides of the outer wall of the inner frame. The multiple threaded sleeves are slidably connected to the corresponding mounting holes. Multiple bolts are provided on the left and right sides of the outer wall of the outer frame. The inner walls of the multiple bolts are threaded with threaded holes. The multiple threaded holes are threadedly connected to the corresponding threaded sleeves.

[0008] Through the above technical solution: when the connecting mechanism is working, the threaded sleeve is first slid into place along the mounting holes on the left and right sides of the inner frame outer wall to lay the foundation for the connection. The bolts on the left and right sides of the outer frame outer wall are screwed into the parts with threaded holes. As the bolts are screwed into the threaded holes, they are threadedly connected with the corresponding threaded sleeves, generating tension to bring the inner frame and outer frame closer to each other and tighten the connection, ensuring the stability of the aluminum alloy door and window structure.

[0009] As a further description of the above technical solution: The protective component includes a window frame, the outer wall of which is fixedly connected to the middle of the inner wall of the inner frame and the outer frame. Windows are slidably connected to the left and right sides of the inner wall of the window frame, and glass panels are fixedly connected to the front and back sides of the inner walls of the two windows.

[0010] The above technical solution involves fixing the outer wall of the window frame to the middle of the inner and outer frames to form a stable frame. The window is slidably connected to the window frame on the left and right sides of the inner wall, allowing users to achieve ventilation and lighting functions by sliding the window. The glass panel is fixed to the front and back sides of the inner wall of the window, which not only provides lighting and views but also blocks external dust and wind and rain to a certain extent, thus playing a protective role.

[0011] As a further description of the above technical solution: The dustproof component includes multiple plugs, the outer walls of which are slidably connected to the corresponding reserved openings, and multiple anti-slip strips are fixedly connected to the outer walls of each of the multiple plugs.

[0012] Through the above technical solution: when the dustproof component is working, the plug slides into the reserved opening, and the anti-slip strip on the outer wall increases the friction, making it firmly plugged in the reserved opening and preventing dust from entering.

[0013] As a further description of the above technical solution: The inner frame and the outer frame are provided with the same rubber ring on their outer walls. Multiple reserved grooves are provided on the upper and lower sides of the outer wall of the rubber ring. Screws are threaded to the inner walls of the multiple reserved grooves. The multiple screws are threaded to the corresponding inner frame and outer frame, respectively.

[0014] The above technical solution provides a mounting position for screws by pre-drilling grooves on the rubber ring. The screws are screwed into the pre-drilled grooves and connected to the inner and outer frames respectively by threads, thereby firmly fixing the rubber ring and filling the gaps between the inner and outer frames and the wall, thus enhancing the sealing and heat insulation.

[0015] As a further description of the above technical solution: The inner wall of the window frame has two sliding grooves, and the upper and lower sides of the outer walls of the two windows are rotatably connected to multiple rollers, which are respectively slidably connected to the corresponding sliding grooves.

[0016] The above technical solution involves a sliding groove on the inner wall of the window frame that works in conjunction with rollers that rotate on the upper and lower sides of the outer wall of the window. When the window is pushed, the rollers slide in the sliding groove, reducing friction and allowing the window to open and close smoothly within the window frame.

[0017] As a further description of the above technical solution: The outer wall of the inner frame is provided with multiple hexagonal slots on both the left and right sides, and the multiple threaded sleeves are respectively engaged with the corresponding hexagonal slots.

[0018] The above technical solution involves the engagement of the hexagonal groove on the outer wall of the inner frame with the threaded sleeve, which restricts the rotation of the threaded sleeve and ensures that the position of the threaded sleeve is stable when connecting the inner and outer frames, thus guaranteeing a stable connection structure.

[0019] As a further description of the above technical solution: Hexagonal holes are provided on the rear side of the outer wall of each of the bolts, and the inner walls of the hexagonal holes are treated with anti-slip treatment.

[0020] The above technical solution involves a hexagonal hole on the rear side of the bolt's outer wall, with an inner anti-slip treatment to facilitate tool insertion, increase friction, and allow operators to tighten the bolt more steadily and effectively.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the heat insulation plate 1 and heat insulation plate 2 between the inner frame and the outer frame are inserted into the corresponding installation grooves for initial fixation and to block heat transfer. The outer and inner heat insulation strips are inserted into the gaps through the reserved openings to enhance heat insulation. The anti-slip strips are used to block the dust in the reserved openings to avoid affecting the heat insulation. The rubber rings fill the gaps in the wall for further heat insulation. The vacuum design between the glass plates enhances heat insulation. These structures work together to solve the problems of limited thermal resistance and poor heat insulation performance of the existing single nylon spacer.

[0022] 2. In this utility model, the threaded sleeve is inserted into the mounting hole of the inner frame, and then the threaded hole is screwed into the bolt of the outer frame. As the threaded hole is screwed in, the inner and outer frames move towards each other, firmly clamping the first heat insulation plate and the second heat insulation plate. This not only firmly connects the inner frame and the outer frame, but also ensures the stability of the heat insulation components and improves the overall heat insulation performance. At the same time, the hexagonal hole with anti-slip treatment on the threaded hole provides convenience for the operator and ensures that the connection operation is carried out smoothly, solving the problems of unstable connection and poor fixation of heat insulation components.

[0026] Reference Figure 3 , Figure 4 and Figure 6 The present invention provides an embodiment of an aluminum alloy door and window structure for blocking thermal bridges, comprising an inner frame 1 and an outer frame 4. The inner frame 1 serves as the internal frame structure of the door and window, providing an installation base for internal components and working with other components to form a complete door and window structure. A heat insulation mechanism 2 is provided between adjacent parts of the inner frame 1 and the outer frame 4 to block heat conduction between the inner frame 1 and the outer frame 4, thereby improving the heat insulation performance of the door and window. A connecting mechanism 3 is provided between adjacent parts of the inner frame 1 and the outer frame 4. Insulation plates 201 are provided on the upper and lower sides of the inner frame 1 and the connecting mechanism 3 to enhance the insulation effect in the vertical direction and further block the heat transfer between the inner frame 1 and the outer frame 4. Insulation plates 202 are provided on the left and right sides of the inner frame 1 and the outer frame 4 to enhance the insulation effect in the horizontal direction. Together with the insulation plates 201, they improve the overall insulation performance. Mounting grooves 203 are provided on the upper and lower sides of the adjacent ends of the inner frame 1 and the outer frame 4 to provide installation positions for the insulation plates 201, enabling them to be accurately installed and perform their insulation function. Mounting grooves 204 are provided on the left and right sides of the adjacent ends of the inner frame 1 and the outer frame 4 to provide installation positions for the insulation plates 202, ensuring that the insulation plates 202 are installed firmly and can effectively insulate. The two insulation plates 201 and 202 are slidably connected to the corresponding mounting grooves 203 and 204, respectively, to facilitate insulation. The installation and removal of the heat plate 1 201 and the heat insulation plate 202 ensure that they can stably perform their heat insulation function after installation. The four corners of the outer walls of the inner frame 1 and the outer frame 4 are provided with reserved openings 205 to provide installation space for the subsequent installation of dustproof components 209 and other sealing components. The outer walls of the adjacent side of the inner frame 1 and the outer frame 4 are provided with external heat insulation strips 206 to further enhance the heat insulation performance of the outside of the door and window and reduce the heat entering from the outside. The inner walls of the adjacent side of the inner frame 1 and the outer frame 4 are provided with internal heat insulation strips 207 to enhance the heat insulation performance of the inside of the door and window and prevent heat loss from the inside. The inner frame 1 is provided with protective components 208 to protect the internal structure of the door and window and provide users with normal door and window functions. The four corners of the outer walls of the inner frame 1 and the outer frame 4 are provided with dustproof components 209 to prevent dust from entering from the gaps at the corners of the door and window and keep the inside of the door and window clean. The protective component 208 includes a window frame 2081, which serves as the mounting carrier for the window 2082 and is connected to the inner frame 1 and the outer frame 4 to form a complete door and window frame. The outer wall of the window frame 2081 is fixedly connected to the middle of the inner wall of the inner frame 1 and the outer frame 4. The windows 2082 are slidably connected to the left and right sides of the inner wall of the window frame 2081. The sliding connection between the windows 2082 and the window frame 2081 facilitates the user to open and close the door and window, and realizes the functions of ventilation and lighting. The front and rear sides of the inner walls of the two windows 2082 are fixedly connected to glass panels 2083 to provide lighting function, while enhancing the heat insulation and sound insulation performance of the door and window. Specifically, the inner frame 1 and outer frame 4 serve as the main frame, connected by the thermal insulation mechanism 2 and the connecting mechanism 3. Thermal insulation plate one 201 and thermal insulation plate two 202 are inserted into their corresponding mounting slots one 203 and two 204, respectively, not only initially fixing the inner frame 1 and outer frame 4 but also blocking heat transfer due to their excellent thermal insulation properties. The outer thermal insulation strip 206 and the inner thermal insulation strip 207 are placed in the gap between the inner frame 1 and outer frame 4, further enhancing the thermal insulation effect. In the protective assembly 208, the window frame 2081 is fixed in the middle of the inner wall of the inner and outer frames 4, the window 2082 can slide within the window frame 2081 for easy opening and closing of doors and windows, and the glass plate 2083 is fixed to the inner wall of the window 2082, providing lighting and thermal insulation functions. Furthermore, the vacuum state between the glass plates 2083 further enhances the thermal insulation performance. Dustproof components 209 are installed at the four corners of the outer walls of the inner frame 1 and outer frame 4. Their plugs 2091 are securely fastened to the reserved openings 205 by means of anti-slip strips 2092 to prevent dust from entering. In addition, rubber rings 5 ​​are fitted on the outer sides of the inner frame 1 and outer frame 4 and fixed with screws 7 to fill the gaps between the inner frame 1 and the wall, ensuring comprehensive heat insulation. All components work together to improve the overall performance of the doors and windows.

[0027] Reference Figure 2 , Figure 7 and Figure 8 The connecting mechanism 3 includes multiple threaded sleeves 301, which serve as intermediate transition components connecting the inner frame 1 and the outer frame 4, providing a key node for achieving a stable connection between the two. Multiple mounting holes 302 are provided on the left and right sides of the outer wall of the inner frame 1 to provide mounting positions for the threaded sleeves 301, ensuring that the threaded sleeves 301 can be accurately installed on the inner frame 1. The multiple threaded sleeves 301 are slidably connected to the corresponding mounting holes 302, which facilitates the adjustment of the position of the threaded sleeves 301 within the mounting holes 302 to better align with the bolts 303 on the outer frame 4. Multiple bolts 303 are provided on the left and right sides of the outer wall of the outer frame 4, which cooperate with the threaded holes 304 to achieve the connection between the two. The inner walls of the multiple bolts 303 are threadedly connected to the threaded holes 304. The function of the threaded connection with the bolts 303 is to generate relative displacement between the outer frame 4 and the inner frame 1 by rotating the threaded holes 304, thereby achieving a tight connection between the two. The multiple threaded holes 304 are threadedly connected to the corresponding threaded sleeves 301. Specifically, multiple mounting holes 302 on the left and right sides of the outer wall of the inner frame 1 provide mounting positions for threaded sleeves 301, which can slide within them for easy adjustment to align with the connecting components on the outer frame 4. Multiple bolts 303 on the left and right sides of the outer wall of the outer frame 4 are threadedly connected to threaded holes 304, forming one end of the connection. The threaded holes 304 are also threadedly connected to the corresponding threaded sleeves 301. When the threaded holes 304 are rotated, axial force is generated due to the threaded engagement with the threaded sleeves 301. As the threaded holes 304 are continuously screwed in, this axial force brings the inner frame 1 and outer frame 4 closer together and tightly connects them. The multiple threaded sleeves 301, mounting holes 302, bolts 303, and threaded holes 304 work together, evenly distributing the connection points, making the connection between the inner frame 1 and outer frame 4 more stable. This ensures that the entire aluminum alloy door and window structure can withstand various external forces during use, maintain structural integrity, and lay a solid foundation for achieving the heat insulation and protection functions of the doors and windows.

[0028] Reference Figure 3 , Figure 4 and Figure 5 The dustproof component 209 includes multiple plugs 2091 that fill the reserved openings 205, thereby preventing dust from entering the internal structure of the door and window through the reserved openings 205. The outer walls of the multiple plugs 2091 are slidably connected to the corresponding reserved openings 205, facilitating the installation of the plugs 2091 into the reserved openings 205 and ensuring that the plugs 2091 are accurately positioned. Multiple anti-slip strips 2092 are fixedly connected to the outer walls of the multiple plugs 2091 to increase the friction between the plugs 2091 and the reserved openings 205, preventing the plugs 2091 from slipping out of the reserved openings 205 and ensuring the durability of the dustproof effect; the outer walls of the inner frame 1 and the outer frame 4... A single rubber ring 5 is provided to fill the gap between the inner frame 1, the outer frame 4 and the wall, enhancing the sealing of the connection between the door / window and the wall, and playing a role in sound insulation, heat insulation and dust prevention. Multiple reserved grooves 6 are provided on the upper and lower sides of the outer wall of the rubber ring 5 to provide installation positions for screws 7, so that the rubber ring 5 can be fixed on the inner frame 1 and the outer frame 4. The inner walls of the multiple reserved grooves 6 are threaded with screws 7. The purpose of the threaded connection with the reserved grooves 6 is to allow the screws 7 to be screwed into the reserved grooves 6 and to engage with the threads of the inner frame 1 and the outer frame 4 to achieve a stable installation of the rubber ring 5. The multiple screws 7 are respectively threaded to the corresponding inner frame 1 and outer frame 4. Specifically, the reserved openings 205 are located at the four corners of the outer walls of the inner frame 1 and the outer frame 4. The outer wall of the plug 2091 is slidably connected to the reserved openings 205, allowing for easy installation. Multiple anti-slip strips 2092 are fixedly connected to the outer wall of the plug 2091, increasing the friction between the plug 2091 and the reserved openings 205, preventing the plug 2091 from sliding or falling out within the reserved openings 205, thus tightly sealing the reserved openings 205. This effectively prevents dust from entering the space between the inner frame 1 and the outer frame 4 from the gaps at these corners, keeping the internal structure clean and avoiding dust affecting the performance of heat insulation and other components. The outer walls of the inner frame 1 and the outer frame 4 are equipped with the same rubber ring 5, which is mainly used to fill the gaps between the doors / windows and the wall. The rubber ring 5 has good elasticity and sealing properties, effectively blocking heat transfer through the connection between the doors / windows and the wall, further enhancing the heat insulation performance of the doors / windows. Multiple pre-drilled grooves 6 on the upper and lower sides of the outer wall of the rubber ring 5 provide installation positions for the screws 7. The screws 7 are threaded into the inner wall of the pre-drilled grooves 6 and respectively into the inner frame 1 and outer frame 4. By tightening the screws 7, the rubber ring 5 can be firmly fixed to the inner frame 1 and outer frame 4, ensuring that the rubber ring 5 will not shift or fall off during long-term use, and always maintains effective filling of the gap between the door / window and the wall, maintaining a good sealing and heat insulation effect.

[0029] Reference Figure 7 , Figure 8 and Figure 9 The inner wall of the window frame 2081 has two grooves 8, providing sliding tracks for the rollers 9, allowing the window 2082 to move smoothly between the inner frame 1 and the outer frame 4 along a set path. Multiple rollers 9 are rotatably connected to the upper and lower sides of the outer walls of both windows 2082. Their rotatable connection reduces friction during movement, making the pushing and pulling operation of the windows 2082 smoother. Each roller 9 is slidably connected to its corresponding groove 8. Hexagonal holes 11 are provided on the rear side of the outer wall of multiple bolts 303 for machining. The tool provides a force application point, making it convenient for operators to tighten or loosen the bolt 303 using the corresponding tools. The inner walls of the multiple hexagonal holes 11 are all treated with anti-slip material to increase the friction between the tool and the inner wall of the hexagonal hole 11, making it less likely for the tool to slip during operation and improving the accuracy and convenience of operation. Multiple hexagonal grooves 10 are opened on the left and right sides of the outer wall of the inner frame 1, which cooperate with the threaded sleeve 301 to restrict the rotation of the threaded sleeve 301 and ensure the stability of the connection structure. The multiple threaded sleeves 301 are respectively engaged with the corresponding hexagonal grooves 10. Specifically, the sliding track 8 and multiple rollers 9 rotatably connected to the upper and lower sides of the outer wall of the window 2082 form a sliding pair. When the window 2082 needs to be opened or closed, the rollers 9 slide smoothly in the sliding track 8, allowing the window 2082 to move easily within the window frame 2081, providing convenience for user operation and ensuring the stability of the window 2082 during movement. The hexagonal holes 11 on the rear side of the outer wall of the bolts 303 on the outer frame 4 have anti-slip treatment on their inner walls. This design allows construction workers to easily insert the hexagonal holes 11 using appropriate tools such as hex wrenches. The side hole 11, with the friction provided by the anti-slip treatment, tightens the bolt 303 more stably and efficiently, thereby firmly screwing the threaded hole 304 into the bolt 303, realizing the tight connection between the outer frame 4 and the inner frame 1 through the connecting mechanism 3; the hexagonal groove 10 cooperates with the threaded sleeve 301, and the threaded sleeve 301 engages with the corresponding hexagonal groove 10. This engaging structure effectively restricts the rotation of the threaded sleeve 301. When the threaded hole 304 is screwed into the threaded sleeve 301, the threaded sleeve 301 will not rotate due to force, ensuring the stability of the connection process.

[0030] Working Principle: In use, first, the inner frame 1 and outer frame 4 are placed upright to prepare for subsequent assembly. Next, the two heat insulation plates 201 are inserted into their corresponding mounting slots 203, and then the two heat insulation plates 202 are inserted into their corresponding mounting slots 204. This step not only initially fixes the inner frame 1 and outer frame 4 together, but also ensures that the heat insulation plates 201 and 202 have good heat insulation performance, effectively blocking heat transfer between the inner frame 1 and outer frame 4, thus laying the structural foundation for blocking thermal bridges. Afterward, the outer heat insulation strip 206 and inner heat insulation strip 207 are inserted into the gap between the inner frame 1 and outer frame 4 through their corresponding pre-drilled openings 205 to further enhance the heat insulation effect. Next, the plug 2091 is installed. The anti-slip strip 2092 on the plug 2091 prevents it from sliding within the pre-drilled opening 205, allowing the plug 2091 to be securely held in place, preventing dust from entering, keeping the interior of the door and window clean, and avoiding any impact on the thermal insulation performance. Then, the rubber ring 5 is fitted onto the outer sides of the inner frame 1 and outer frame 4, and screws 7 are used to fix the rubber ring 5 to the inner frame 1 and outer frame 4. The rubber ring 5 fills the gaps between the inner frame 1 and outer frame 4 and the wall, effectively preventing heat transfer from the connection between the wall and the door / window, further ensuring the thermal insulation effect. Finally, the window 2082 can slide smoothly within the window frame 2081, facilitating easy opening and closing of the door and window. The corresponding two glass panels 2083 are in a vacuum state. Vacuum has extremely low thermal conductivity, which further enhances the thermal insulation performance, comprehensively solving the problem of poor thermal insulation performance in existing technologies and providing better temperature insulation for the interior. After the inner frame 1, outer frame 4, and heat insulation plate 1 201 and heat insulation plate 202 are assembled, the connection operation begins. First, the threaded sleeve 301 is inserted into the corresponding mounting holes 302 on the left and right sides of the outer wall of the inner frame 1, providing a basic support point for the subsequent connection. Next, the component with the threaded hole 304 is screwed into the bolts 303 on the left and right sides of the outer wall of the outer frame 4. During the screwing process, as the threaded hole 304 is continuously tightened, the mounting groove 204 can enter the inner wall of the threaded sleeve 301. As the threaded hole 304 is continuously tightened, the distance between it and the threaded sleeve 301 gradually decreases, and the resulting tension causes the inner frame 1 and the outer frame 4 to move towards each other, thereby tightly clamping the heat insulation plate 1 201 and the heat insulation plate 202, achieving a firm fixation between the inner frame 1 and the outer frame 4. The hexagonal holes 11 with anti-slip treatment opened on the rear side of the outer wall of the multiple threaded holes 304 provide better friction and force points for operators to tighten the threaded holes 304 with tools, making operation easier and ensuring the stability of the connection.
