Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to an aluminum alloy door and window frame. Background Technology

[0002] Aluminum alloy door and window frames refer to the supporting structures made primarily of aluminum alloy profiles used for installing door and window glass. They are widely used in the construction industry to meet the needs of indoor and outdoor space isolation and lighting. Aluminum alloy, due to its lightweight, corrosion resistance, and high strength, has become an important material for door and window frame manufacturing. Currently, common aluminum alloy door and window frames typically consist of components such as frame edges, mullions, and glass strips, which are connected by connectors or welding processes to form an integral structure. To enhance the sealing and wind pressure resistance of the door and window frames, some designs also incorporate auxiliary components such as thermal break strips or reinforcing ribs.

[0003] However, existing aluminum alloy door and window frames still have certain limitations in practical applications. For example, during installation, due to the large number of frame components and their fixed dimensions, handling and adjustment often require significant time and labor costs. Furthermore, while some frames adopt a modular design concept, their assembly methods mostly rely on horizontal splicing or single-direction adjustment, making it difficult to achieve flexible vertical adaptation. This design may lead to reduced installation efficiency when facing door and window openings of different sizes, and also limits its adaptability to special scenarios. Therefore, there is an urgent need for an aluminum alloy door and window frame that can optimize installation convenience and adaptability. Utility Model Content

[0021] The specific embodiments of the aluminum alloy door and window frame of this utility model are described in detail with reference to the accompanying drawings. Figure 1 As shown, the main frame assembly 1 consists of a frame unit 3 and a mullion unit 4, which are detachably connected by connectors. An auxiliary adjustment assembly 2 is located inside the main frame assembly 1 and connected to the frame unit 3. A sealing strip 5 is fixed to the outside of the main frame assembly 1, and a heat insulation strip 11 is embedded in the inner groove of the frame unit 3. A sliding mechanism 6 is installed in the slide groove 8 of the frame unit 3, and its slider 10 works in conjunction with the adjusting rod 7. The following provides a detailed description of the specific structure, connection relationships, and operation of the components.

[0022] The frame unit 3 includes a first frame and a second frame, which are connected by a hinge. One end of the hinge is embedded in an inner groove of the first frame, and the other end is fixed to an outer protrusion of the second frame by a bolt. Both the first and second frames have inner grooves 8 with a T-shaped cross-section to accommodate the slider 10 of the sliding mechanism 6. A positioning hole is provided at the bottom of the groove 8 for inserting a positioning pin to fix the position of the sliding mechanism 6. The design of the groove 8 allows the slider 10 to move linearly within the groove 8, while the positioning hole and positioning pin work together to lock the position.

[0023] The mullion unit 4 includes a first mullion and a second mullion, which are connected by a snap-fit ​​structure. One end of the snap-fit ​​structure has an elastic protrusion, and the other end has a groove that matches the elastic protrusion. Both sides of the first and second mullions have insertion slots for use with the connectors of the frame unit 3. The main body of the connector is a rectangular plate structure with insertion connectors at both ends, the shape of which matches the insertion slots. The surface of the insertion connectors is coated with an anti-slip coating to enhance connection stability. The installation process of the connector is as follows: after inserting the insertion connector into the insertion slot, the friction of the anti-slip coating ensures that the connector will not easily loosen.

[0024] The auxiliary adjustment assembly 2 includes an adjustment rod 7 and a support plate. One end of the adjustment rod 7 is fixedly connected to the support plate, and the other end is connected to the slider 10 of the sliding mechanism 6 via a thread. A locking nut is fitted onto the outside of the adjustment rod 7 to fix its position. Reinforcing ribs with a wavy cross-section are provided on the inner side of the support plate to improve its bending strength. Multiple mounting holes are provided on the outer side of the support plate for fixing glass retaining strips or other additional components. During actual installation, rotating the adjustment rod 7 moves the slider 10 along the slide rail 9, thereby changing the overall size of the main frame assembly 1. Once the target size is reached, the locking nut is used to fix the position of the adjustment rod 7, completing the size adjustment.

[0025] The sliding mechanism 6 includes a slide rail 9 and a slider 10. The slide rail 9 is fixedly installed in the slide groove 8 of the frame unit 3, and the slider 10 is slidably connected to the slide rail 9. The top of the slider 10 has a threaded hole for engaging with the threaded end of the adjusting rod 7. The bottom of the slider 10 has ball bearings that contact the inner wall of the slide rail 9 to reduce friction during sliding. Limit blocks are provided at both ends of the slide rail 9 to prevent the slider 10 from disengaging from the slide rail 9. The working principle of the sliding mechanism 6 is as follows: when the adjusting rod 7 rotates, its threaded end engages with the threaded hole of the slider 10, pushing the slider 10 to move along the slide rail 9. The ball bearing design of the slider 10 reduces movement resistance, while the limit blocks ensure that the slider 10 always remains within the slide rail 9, preventing it from falling off due to excessive movement.

[0026] The sealing strip 5 includes a main body and an extension. The main body is fixedly mounted on the outside of the frame unit 3, and the extension bends inward and contacts the glass surface. The main body of the sealing strip 5 has an internal cavity filled with an elastic material. The surface of the extension of the sealing strip 5 has micro-protrusions to increase friction with the glass surface. The installation process of the sealing strip 5 is as follows: the main body is embedded into the outer groove of the frame unit 3, and then the elastic material's resilience allows the extension to fit tightly against the glass surface. The micro-protrusion design further enhances the contact effect between the sealing strip 5 and the glass, thereby improving the overall sealing performance.

[0027] The thermal insulation strip 11 has a U-shaped cross-section, and claws are provided on both sides of the thermal insulation strip 11. The claws are used to cooperate with the inner grooves of the frame unit 3. The interior of the thermal insulation strip 11 is filled with aerogel material. The installation process of the thermal insulation strip 11 is as follows: insert the claws into the inner grooves of the frame unit 3, and fix it by the elastic deformation of the claws. The low thermal conductivity of the aerogel material further reduces the possibility of heat transfer through the thermal insulation strip 11, thereby improving the overall thermal insulation performance.

[0028] The bottom of frame unit 3 is equipped with a drainage channel, which has a V-shaped cross-section to guide rainwater to drain quickly. A drainage hole with a diameter of 5mm is provided at the bottom of the drainage channel to drain accumulated water to the outside. A filter screen is installed inside the drainage channel to prevent debris from entering. The design of the drainage channel allows rainwater to quickly collect along the V-shaped channel and drain from the drainage hole, while the filter screen effectively prevents debris from clogging the drainage hole.

[0029] A decorative cover plate is provided on the outer side of the main frame component 1, and the decorative cover plate is connected to the frame unit 3 via a magnetic attraction device. The magnetic attraction device includes a magnet and a metal sheet; the magnet is embedded in the inner side of the decorative cover plate, and the metal sheet is fixedly set on the outer side of the frame unit 3. The surface of the decorative cover plate is provided with an anti-slip texture. The installation process of the decorative cover plate is as follows: the decorative cover plate is brought close to the frame unit 3, and the magnet and the metal sheet attract each other, thereby achieving fixation. The anti-slip texture design not only enhances the tactile feel of the decorative cover plate but also improves the overall aesthetics.

[0030] A lighting device is installed on the top of the main frame assembly 1, and the lighting device is connected to a power source via wires. The housing of the lighting device is made of waterproof material, and the light source is LED beads, which are evenly distributed on the inside of the housing. The installation process of the lighting device is as follows: the housing is fixed to the top of the main frame assembly 1, and the power source is connected via wires. The choice of waterproof material ensures the durability of the lighting device in harsh environments, while the even distribution of LED beads provides good lighting effect.

[0031] The connection relationships and operation processes of the aforementioned components together constitute the complete implementation of this utility model. In practical applications, the overall dimensions of the main frame assembly 1 are first adjusted according to the size of the door and window openings. By rotating the adjusting rod 7, the slider 10 moves along the slide rail 9, changing the width or height of the main frame assembly 1. After adjustment, the position of the adjusting rod 7 is fixed using a locking nut. Subsequently, the sealing strip 5 is embedded into the outer groove of the frame unit 3, and its elasticity is used to ensure a tight fit against the glass surface. The heat insulation strip 11 is fixed in the inner groove of the frame unit 3 by clips, further improving the heat insulation performance. Finally, the decorative cover plate and lighting device are installed to complete the assembly of the overall frame.

[0032] In this embodiment, the connection relationships of all components are clearly defined, and the installation process of each component is highly operable. Through the above steps, this utility model achieves flexible adaptation to door and window openings of different sizes, while significantly improving installation efficiency and overall performance.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.

[0034] When actually installing aluminum alloy door and window frames, the overall size of the main frame assembly 1 is first adjusted according to the actual dimensions of the door and window openings. The operator rotates the adjusting rod 7, which engages with the threaded hole at the top of the slider 10, pushing the slider 10 along the slide rail 9. At this time, the ball bearings at the bottom of the slider 10 contact the inner wall of the slide rail 9, reducing friction and ensuring smooth sliding, while the limiting blocks at both ends of the slide rail 9 prevent the slider 10 from disengaging from the track. Once the width or height of the main frame assembly 1 is adjusted to fit the target size, the locking nut is used to fix the position of the adjusting rod 7, thereby locking the size of the main frame assembly 1. This process achieves flexible adaptation to door and window openings of different sizes and significantly improves installation efficiency.

[0035] Subsequently, the sealing strip 5 is embedded into the outer groove of the frame unit 3. The internal cavity of the main body of the sealing strip 5 is filled with elastic material. During the embedding process, the resilience of the elastic material allows the extension of the sealing strip 5 to fit tightly against the glass surface. At the same time, the tiny protrusions on the surface of the extension of the sealing strip 5 further increase the friction with the glass surface, thereby enhancing the overall sealing performance. This design effectively prevents the leakage of rainwater and air, meeting the high sealing requirements of door and window frames.

[0036] Next, the thermal insulation strip 11 is inserted into the inner groove of the frame unit 3 using the clips on both sides. The elastic deformation of the clips allows the thermal insulation strip 11 to be firmly fixed in the groove. The aerogel material filling the thermal insulation strip 11 has an extremely low thermal conductivity, which can effectively block the heat transfer path, thereby improving the overall thermal insulation performance of the frame. This structural design not only simplifies the installation process but also significantly enhances the energy-saving effect of the door and window frame.

[0037] In the bottom drainage channel of the main frame component 1, rainwater quickly collects along the V-shaped groove and is discharged through the drainage holes. A filter screen installed inside the drainage channel prevents debris from entering, avoiding the risk of clogging the drainage holes. This design ensures that rainwater can be discharged rapidly while maintaining the long-term stability of the drainage system.

[0038] The decorative cover plate is connected to the frame unit 3 via a magnetic attachment. The operator simply needs to bring the cover plate close to the frame unit 3, and the magnets attract the metal sheet to secure it. The anti-slip texture on the surface of the cover plate not only enhances the tactile feel but also improves the overall aesthetics. This design simplifies the installation process of the decorative cover plate while adding a touch of refinement to the frame's appearance.

[0039] Finally, the lighting unit is secured to the top of the main frame assembly 1 and connected to a power source via wires. The housing of the lighting unit is made of waterproof material, ensuring durability in harsh environments. LED beads are evenly distributed inside the housing, providing excellent illumination. This design not only enhances the functionality of the door and window frames but also provides convenience for nighttime use.

[0040] The above steps demonstrate the specific operational process and operating principle of this utility model in practical applications. Through the synergistic effect of its components, this utility model achieves flexible adaptation to door and window openings of different sizes, while significantly improving installation efficiency and overall performance. The connection relationships of all components are clearly defined, the installation process is highly operable, and it can meet the needs of actual engineering projects.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are prior art, and will not be described further here.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
