Technical Field
[0001] This utility model belongs to the field of aluminum profile technology, and specifically relates to an aluminum profile for home use. Background Technology
[0002] Aluminum profiles for home furnishings are made from aluminum alloys such as 6063 / 6061, formed by hot-melt extrusion and surface treatments such as anodizing and electrostatic spraying. They are a core material for home furnishings, combining advantages such as lightweight and high strength (density is only 1 / 3 of steel, strength reaches 70% of ordinary steel), corrosion resistance and moisture resistance, environmental protection with no formaldehyde, and 100% recyclability. They can be processed into various cross-sections such as solid, hollow, and irregular shapes, and are widely used in doors and windows (including thermally broken type), furniture frames (such as European standard 3030 / 4040 series), decorative lines, bathroom brackets, etc. Their modular design facilitates assembly and customization, and their service life reaches 20-30 years. They can take into account energy saving, practicality and aesthetic needs, making them an ideal choice to replace wood and steel in modern homes.
[0003] Existing aluminum profiles for home furnishings still have several shortcomings that urgently need to be addressed: First, their modular assembly performance is poor. Most profiles use a single bolt locking mechanism or a simple plug-in structure, resulting in low positioning accuracy, cumbersome assembly processes, and difficulty in quick assembly without specialized tools. Furthermore, long-term use can lead to loosening and shifting, affecting structural stability. Second, their comprehensive functional integration is insufficient. Traditional profiles often focus on single strength or corrosion resistance, with weak designs for functions such as heat insulation, sound insulation, and shock absorption, making it difficult to meet the high-quality demands of modern homes for quietness, energy efficiency, and comfort. Third, there is an imbalance between structural strength and functional adaptability. Some profiles sacrifice load-bearing capacity and deformation resistance in pursuit of lightweighting, making them prone to deformation in scenarios such as large-span furniture frames and wide doors and windows. On the other hand, profiles that prioritize strength often neglect functional diversity, failing to fully adapt to diverse home application scenarios. Utility Model Content
[0004] In response to the problems mentioned in the background art, the purpose of this utility model is to provide an aluminum profile for home furnishings to solve the problems of poor modular assembly performance, the fact that most of them adopt a single bolt locking or simple plug-in structure, which has problems such as low positioning accuracy, cumbersome assembly process, difficulty in quick assembly without professional tools, and easy loosening and displacement after long-term use, affecting the structural stability.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A type of aluminum profile for home furnishing includes a first profile body and a second profile body. An assembly block is fixedly connected to one end of the second profile body, and a positioning block is fixedly connected to one end of the first profile body. A positioning groove is formed on one side of the assembly block, and the positioning block and the positioning groove are plugged in. Positioning components are installed on both sides inside the positioning groove. A nut groove is formed on the top of the assembly block, and a first threaded hole is formed at the bottom of the nut groove, which communicates with the inside of the positioning groove. A second threaded hole is formed on the top of the positioning block, and the first threaded hole communicates with the second threaded hole. Threaded posts are threadedly connected inside the first threaded hole and the second threaded hole, and a nut is fixedly connected to the top of the threaded post. The assembly method adopts a combination of plug-in connection, positioning components, and threaded locking, which ensures precise positioning, firm fixation, and effectively prevents loosening. It can be quickly assembled without complicated tools and is suitable for modular assembly needs in home furnishing.
[0006] As a preferred technical solution, the positioning component includes an internal hole, a return spring, and a positioning post. Internal holes are provided on both sides of the positioning groove. A return spring is fixedly connected to the bottom of the internal hole, and a positioning post is fixedly connected to the other end of the return spring. The positioning post is slidably connected to the internal hole. The other end of the positioning post extends into the positioning groove and is arc-shaped. Positioning holes are provided on both sides of the positioning block. The positioning post and the positioning hole are snapped together. The positioning component drives the positioning post to snap into the positioning hole through the return spring. The arc-shaped design makes the insertion smoother, the pre-fixing effect reliable, prevents assembly misalignment, and improves the overall assembly stability.
[0007] As a preferred technical solution, both the first profile body and the second profile body are fixedly connected with reinforcing beams. The reinforcing beams are T-shaped and integrally formed with the profile body. This can efficiently disperse external forces, significantly enhance the profile's resistance to bending and deformation, and ensure long-term structural stability in home settings.
[0008] As a preferred technical solution, both the first profile body and the second profile body include an outer layer, a middle layer and an inner layer. The outer layer is fixedly attached to one side of the middle layer by a composite extrusion process and a polyurethane structural adhesive, and the inner layer is attached to the other side of the middle layer by a composite extrusion process and a modified acrylic hot melt adhesive. The three-layer composite structure, combined with the composite extrusion process and the special structural adhesive, ensures tight interlayer bonding, reliable connection and is not easy to peel off, providing a solid structural support for the multi-functional integration of the profile.
[0009] As a preferred technical solution, the middle layer includes a base layer and a sound insulation layer. The sound insulation layer is fixed on both sides of the base layer through a hot-pressing composite process and a snap-fit connection. The base layer is a composite structure of 6061-T6 high-strength aluminum alloy and aluminum honeycomb core. The sound insulation layer is a composite structure of PA nylon thermal insulation strip, polyurethane foam filling layer and glass fiber sound insulation mesh. The sound insulation layer is tightly bonded to the base layer with hot melt adhesive to form a double thermal and sound insulation barrier. The composite material of the base layer has excellent load-bearing capacity, and the multiple structures of the sound insulation layer work together to form a highly efficient double thermal and sound insulation barrier, fully meeting the needs of home energy saving and quietness.
[0010] As a preferred technical solution, the outer layer includes a decorative layer and an anti-corrosion layer. The decorative layer covers the outside of the anti-corrosion layer and is an electrostatic powder coating. The anti-corrosion layer is a 6063-T5 aluminum alloy anodized film. The decorative layer and the anti-corrosion layer are tightly bonded together by an electrostatic spraying process. The inner side of the anti-corrosion layer and the middle layer are precisely positioned by a composite extrusion process and then bonded and fixed with polyurethane structural adhesive. The decorative layer is aesthetically pleasing and diverse to suit different home styles, while the anti-corrosion layer has strong corrosion resistance. The process is tightly bonded, taking into account both appearance and service life, and is suitable for complex home environments.
[0011] As a preferred technical solution, the inner layer includes a shock-absorbing layer and a protective layer. The protective layer covers the inside of the shock-absorbing layer. The shock-absorbing layer is made of EPDM rubber and is bonded and fixed to the middle layer and the protective layer by modified acrylic hot melt adhesive. The protective layer is made of 3003-H14 aluminum alloy. The shock-absorbing layer effectively buffers and reduces noise, while the protective layer protects the inner layer structure. The bonding and fixing are reliable, reducing wear and noise during use and improving the comfort of home use and the protection of the profile.
[0012] In summary, the present invention has the following main advantages: First, this utility model combines assembly stability and convenience. Pre-fixing is achieved through the insertion and cooperation of the positioning block and the positioning groove, combined with the elastic snap-fit of the positioning component. The arc-shaped design of the positioning post facilitates the smooth insertion of the positioning block, and the return spring provides continuous clamping force. Then, the threaded post passes through the threaded hole for locking, forming a dual fixing structure of "pre-positioning and hard locking", which effectively avoids assembly loosening and can be completed without complicated tools, greatly improving installation efficiency and adapting to the modular assembly needs of home scenarios. Secondly, this utility model boasts excellent comprehensive performance and high structural strength. The multi-layered composite structure has a clear division of labor. The outer layer integrates anti-corrosion and decoration to ensure durability and aesthetics. The middle layer features a double heat insulation and sound insulation structure to enhance the energy-saving and quiet effect of the home. The inner layer's shock-absorbing and protective design reduces noise and component wear. Combined with T-shaped reinforcing beams to enhance the bending and deformation resistance of the profile body, the basic layer composite structure further strengthens the load-bearing performance, comprehensively meeting the diverse material performance requirements of home doors, windows, cabinets, and other scenarios.

[0015] Example
[0016] refer to Figures 1 to 4 This embodiment of an aluminum profile for home use includes a first profile body 1 and a second profile body 2. An assembly block 3 is fixedly connected to one end of the second profile body 2, and a positioning block 5 is fixedly connected to one end of the first profile body 1. A positioning groove 6 is formed on one side of the assembly block 3, and the positioning block 5 is inserted into the positioning groove 6. Positioning components 12 are installed on both sides inside the positioning groove 6. A nut 11 groove 7 is formed on the top of the assembly block 3, and a first threaded hole 8 is formed at the bottom of the nut 11 groove 7, communicating with the interior of the positioning groove 6. A second threaded hole 9 is formed on the top of the positioning block 5. The first threaded hole 8 is connected to the second threaded hole 9. The first threaded hole 8 and the second threaded hole 9 are internally threaded with threaded post 10. The top of the threaded post 10 is fixedly connected with nut 11. During assembly, the positioning block 5 of the first profile 1 is first inserted into the positioning groove 6 of the assembly block 3 of the second profile 2 to complete the initial insertion and positioning. The positioning component 12 works synchronously to achieve pre-fixation. Then, the threaded post 10 is threaded through the first threaded hole 8 of the assembly block 3 and threadedly connected to the second threaded hole 9 of the positioning block 5. The nut 11 is tightened to complete the final locking and achieve a stable splicing of the two profiles.
[0017] refer to Figure 3 The positioning component 12 includes an internal hole 121, a return spring 122, and a positioning post 123. Internal holes 121 are provided on both sides of the positioning groove 6. A return spring 122 is fixedly connected to the bottom of the internal hole 121, and a positioning post 123 is fixedly connected to the other end of the return spring 122. The positioning post 123 is slidably connected to the internal hole 121. The other end of the positioning post 123 extends into the positioning groove 6 and is arc-shaped. Positioning holes 13 are provided on both sides of the positioning block 5. The positioning post 123 is engaged with the positioning hole 13. When the positioning block 5 is inserted into the positioning groove 6, the arc-shaped end of the positioning post 123 is pressed, causing it to slide into the internal hole 121 and compressing the return spring 122. When the positioning block 5 moves to the point where the positioning hole 13 aligns with the positioning post 123, the return spring 122 elastically resets, pushing the positioning post 123 out and engaging it in the positioning hole 13, thus achieving elastic pre-fixation between the positioning block 5 and the positioning groove 6 and preventing displacement after insertion.
[0018] refer to Figure 1 The first profile 1 and the second profile 2 are both fixedly connected with reinforcing beams 4. The reinforcing beams 4 are T-shaped. During the molding process of the first profile 1 and the second profile 2, the T-shaped reinforcing beams 4 are fixed to the inside of the profile body through a composite extrusion process. When in use, the reinforcing beams 4 disperse the external force borne by the profile body through their own T-shaped structure, thereby enhancing the overall bending and deformation resistance of the profile body.
[0019] refer to Figure 4 Both the first profile 1 and the second profile 2 include an outer layer 101, a middle layer 102, and an inner layer 103. The outer layer 101 is fixedly attached to one side of the middle layer 102 by a composite extrusion process and a polyurethane structural adhesive. The inner layer 103 is fixed to the other side of the middle layer 102 by a composite extrusion process and a modified acrylic hot melt adhesive. When the profile is formed, the middle layer 102 is the core. The outer layer 101 is positioned on one side by a composite extrusion process and fixed by applying polyurethane structural adhesive. The inner layer 103 is positioned on the other side by a composite extrusion process and fixed by applying modified acrylic hot melt adhesive. Finally, a three-layer composite structure with the outer layer 101, middle layer 102, and inner layer 103 tightly attached is formed.
[0020] refer to Figure 4 The middle layer 102 includes a base layer 1021 and a sound insulation layer 1022. The sound insulation layer 1022 is fixed on both sides of the base layer 1021 by hot-pressing composite process and snap-fit connection. The base layer 1021 is a composite structure of 6061-T6 high-strength aluminum alloy and aluminum honeycomb core. The sound insulation layer 1022 is a composite structure of PA66 nylon heat insulation strip, polyurethane foam filling layer and glass fiber sound insulation mesh. The sound insulation layer 1022 is tightly bonded to the base layer 1021 by hot melt adhesive to form a double heat insulation and sound insulation barrier. When processing the middle layer 102, the sound insulation layer 1022 is first bonded to both sides of the base layer 1021 by hot-pressing composite process and initially fixed by snap-fit connection. Then, hot melt adhesive is applied to the contact surface of the two to further tighten the bond between the sound insulation layer 1022 and the base layer 1021. By utilizing the load-bearing properties of the base layer 1021 and the heat insulation and sound insulation properties of the sound insulation layer 1022, a dual functional barrier is formed.
[0021] refer to Figure 4The outer layer 101 includes a decorative layer 1011 and an anti-corrosion layer 1012. The decorative layer 1011 covers the outside of the anti-corrosion layer 1012. The decorative layer 1011 is an electrostatic powder coating, and the anti-corrosion layer 1012 is a 6063-T5 aluminum alloy anodized film. The decorative layer 1011 and the anti-corrosion layer 1012 are tightly bonded together by an electrostatic spraying process. The inner side of the anti-corrosion layer 1012 and the middle layer 102 are precisely positioned by a composite extrusion process and then bonded and fixed with polyurethane structural adhesive. When preparing the outer layer 101, an anodized anti-corrosion layer 1012 is first formed on the surface of the 6063-T5 aluminum alloy substrate. Then, the electrostatic powder coating of the decorative layer 1011 is covered and bonded to the outside of the anti-corrosion layer 1012 by an electrostatic spraying process. Finally, the inner side of the anti-corrosion layer 1012 and the middle layer 102 are positioned by composite extrusion and bonded with polyurethane structural adhesive to complete the connection between the outer layer 101 and the middle layer 102.
[0022] refer to Figure 4 The inner layer 103 includes a shock-absorbing layer 1031 and a protective layer 1032. The protective layer 1032 covers the inside of the shock-absorbing layer 1031. The shock-absorbing layer 1031 is made of EPDM rubber and is bonded and fixed to the middle layer 102 and the protective layer 1032 by modified acrylic hot melt adhesive. The protective layer 1032 is made of 3003-H14 aluminum alloy. When assembling the inner layer 103, the EPDM rubber shock-absorbing layer 1031 is first bonded to the middle layer 102 by modified acrylic hot melt adhesive. Then, the same hot melt adhesive is applied to the inside of the shock-absorbing layer 1031, and the 3003-H14 aluminum alloy protective layer 1032 is covered and bonded. The edge of the protective layer 1032 is snapped and limited to the middle layer 102 by a folding process, so as to achieve a stable connection between the inner layer 103 and the middle layer 102 and a buffer protection function.
[0023] Operating principle and advantages: First, the profiles are formed through a composite extrusion process. The middle layer 102 is the core. The outer layer 101 is fixed by composite extrusion and polyurethane structural adhesive. The decorative layer 1011 and the anti-corrosion layer 1012 are bonded together by electrostatic spraying. The inner layer 103 is fixed by composite extrusion and modified acrylic hot melt adhesive. The shock-absorbing layer 1031 is bonded to the protective layer 1032, with the protective layer 1032 having folded edges for positioning. Simultaneously, the T-shaped reinforcing beam 4 is compositely fixed to the interior of the profile. During assembly, the positioning block 5 of the first profile 1 is inserted into the second profile 2 for assembly. The positioning groove 6 of block 3 compresses the positioning post 123 and the reset spring 122. After the positioning hole 13 is aligned with the positioning post 123, the spring resets and pushes the positioning post 123 to snap into place to achieve pre-fixation. Then, the threaded post 10 is threaded through the first threaded hole 8 and the second threaded hole 9 and the nut 11 is tightened to complete the final locking. When in use, the T-shaped reinforcing beam 4 disperses external forces and enhances structural strength. The outer layer 101 achieves anti-corrosion and decorative functions. The middle layer 102 has a double structure to ensure heat insulation and sound insulation effects. The inner layer 103 plays a shock absorption and protection role. The whole achieves stable assembly and multi-dimensional functional synergy. This utility model is easy and efficient to assemble and has strong stability. It has excellent anti-corrosion, decorative, heat insulation, sound insulation and shock absorption protection performance. It has high structural strength and can be fully adapted to diverse home application scenarios. It takes into account both practicality and durability and greatly improves the home user experience.
