Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to an aluminum profile with arc-shaped edges to prevent scratches. Background Technology

[0002] Aluminum profiles, as a lightweight, high-strength, corrosion-resistant, easily processed, and recyclable metal material, are widely used in construction, transportation, electronic equipment, and home furniture. Their excellent physical and mechanical properties, such as good thermal and electrical conductivity, high specific strength, and excellent formability, make them an indispensable structural and decorative material in modern industry. Especially in products such as doors and windows, curtain walls, display racks, and automated equipment housings, aluminum profiles not only provide structural support and connection, but their appearance and safety are also increasingly valued. In recent years, with users' increasing demands for product user-friendliness, safety, and aesthetics, aluminum profile designs increasingly consider contact safety and protective performance during use. Common surface passivation, anodizing, and spraying processes can improve corrosion resistance and aesthetics.

[0003] In actual transportation, installation and use, existing aluminum profile products still cannot completely avoid scratches and bumps to people or objects due to insufficiently smooth edge transitions, small arc radii or lack of auxiliary buffer structures. Especially during installation, the edges of the profiles frequently come into contact with the operator's hands, and traditional edges are prone to significant cutting and puncture when subjected to concentrated force, posing a risk of pinching or scratching.

[0004] Therefore, it is necessary to provide an aluminum profile with a curved edge to prevent scratches and solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum profile with an arc-shaped edge that is scratch-resistant, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: an aluminum profile with arc-shaped edge anti-scratch, comprising an aluminum profile body, wherein the exposed edges of the aluminum profile body have smoothly transitioned arc-shaped outer edges, a buffer elastic strip is embedded in the side wall of the arc-shaped outer edge near the end face of the aluminum profile body, and at least one internal reinforcing rib is provided inside the cross section of the aluminum profile body.

[0007] As a further embodiment of this utility model, the radius R of the arc-shaped outer edge is 0.8mm to 2.5mm.

[0008] As a further embodiment of this utility model, the outer surface of the aluminum profile body is fully covered with a wear-resistant coating.

[0009] As a further embodiment of this utility model, the aluminum profile body is provided with a mounting slot for connecting matching components.

[0010] As a further embodiment of this utility model, a guide groove is provided at the bottom or back of the aluminum profile body.

[0011] As a further embodiment of this utility model, the internal reinforcing ribs are truss-shaped structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. All exposed edges adopt a smooth transition arc-shaped outer edge. The arc-shaped outer edge transforms point or line contact into surface contact. When external force is applied, the force is dispersed along the continuous curved surface, and the local pressure is greatly reduced, thereby effectively avoiding cutting and puncture effects. It achieves passive and physical anti-scratch protection, greatly reducing the risk of users being scratched during transportation, installation and daily use. It also protects the surfaces of furniture, walls and other items in contact with it from damage. 2. The arc-shaped edge processing may have a microscopic effect on the overall stiffness of the profile. This utility model integrates an internal reinforcing rib inside the cross-section of the aluminum profile body. This reinforcing rib, as the "internal skeleton" of the profile, significantly improves its resistance to bending and torsional deformation by increasing the moment of inertia of the profile cross-section. 3. Because the buffer elastic strip is located close to the outer edge of the arc, when an external force is applied, the buffer elastic strip will first undergo elastic compression deformation. The deformation process absorbs part of the collision energy, providing soft cushioning, further improving the protective effect, and effectively reducing the risk of pinching hands during installation.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Please see Figure 1-4 This utility model provides an aluminum profile with arc-shaped edges to prevent scratches, including an aluminum profile body 1. The exposed edges of the aluminum profile body 1 all have smoothly transitioned arc-shaped outer edges 2. A buffer elastic strip 5 is embedded in the side wall of the arc-shaped outer edge 2 near the end face of the aluminum profile body 1, and at least one internal reinforcing rib 3 is provided inside the cross section of the aluminum profile body 1. The edges adopt smoothly transitioned arc-shaped outer edges 2. Sharp edges will produce significant stress concentration. When a collision or scratch occurs, the force is concentrated on a very small point or line, which can easily cause scratches. The curved outer edge 2 transforms point or line contact into surface contact. When external force is applied, the force is dispersed along the continuous curved surface, significantly reducing local pressure and effectively avoiding cutting and puncture effects. This achieves passive, physical scratch protection, greatly reducing the risk of scratches to users during transportation, installation, and daily use. It also protects the surfaces of furniture, walls, and other items in contact with it from damage. The curved edge processing may have a microscopic impact on the overall rigidity of the profile. Therefore, this invention integrates an internal reinforcing rib 3 within the cross-section of the aluminum profile body 1. As the "internal skeleton" of the profile, the ability to resist bending and torsional deformation is significantly improved by increasing the moment of inertia of the profile section. The buffer elastic strip 5 is made of flexible materials such as EPDM rubber and thermoplastic elastomer (TPE), and is fixed in the groove of the profile side wall by the snap-fit ​​structure at its bottom or by adhesive method. The position is close to the arc-shaped outer edge 2 on the end face. When subjected to external force, the buffer elastic strip 5 will first undergo elastic compression deformation. The deformation process absorbs part of the collision energy, provides soft cushioning, further improves the protection effect, and effectively reduces the risk of pinching hands during installation.

[0017] It is worth further elaborating that the radius R of the arc-shaped outer edge 2 is 0.8mm to 2.5mm; it is smooth to the touch and provides sufficient contact area to reach the safety protection threshold, ensuring that it has both excellent safety, aesthetics and functionality.

[0018] Further as Figure 4 As shown, it is worth noting that the outer surface of the aluminum profile body 1 is fully covered with a wear-resistant coating 4. When a hard object or abrasive particle attempts to scratch the surface, this wear-resistant coating 4 is the first to bear and resist the wear, thereby protecting the underlying aluminum substrate, effectively improving the durability of the profile, maintaining the long-term aesthetics of the product, and is particularly suitable for occasions with high-frequency touch, frequent cleaning, or complex environments. It works in conjunction with the curved outer edge 2 to provide more comprehensive protection.

[0019] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the aluminum profile body 1 is provided with mounting slots 6 for connecting matching components. These slots 6 are longitudinal channels with specific geometric shapes (such as T-shapes, dovetail shapes, or hook shapes) manufactured during the aluminum profile extrusion process. When assembling doors, windows, curtain walls, or furniture, related functional accessories, such as glass strips, connecting brackets, decorative covers, or actuators, can be directly and precisely embedded into the mounting slots 6 using their own designed or standard snap-fits or sliders, achieving mechanical interlocking. This significantly improves installation efficiency, reduces labor costs and skill requirements, and enables rapid assembly with no or few tools.

[0020] Further as Figure 1 and Figure 3 As shown, it is worth noting that a guide groove 7 is provided at the bottom or back of the aluminum profile body 1. When water flows down the surface of the profile or enters the cavity, the guide groove 7 collects the water and provides it with a clear and controlled flow path, ultimately guiding the water to the preset drainage hole for discharge, effectively preventing the accumulation of water inside the profile or at the interface.

[0021] Further as Figure 3 As shown, it is worth noting that the internal reinforcing rib 3 has a truss-like structure.

[0022] In summary: all exposed edges adopt a smooth transition with an arc-shaped outer edge 2. Sharp edges will produce significant stress concentration, while the arc-shaped outer edge 2 transforms point or line contact into surface contact. When external force is applied, the force is dispersed along the continuous curved surface, and the local pressure is greatly reduced, thus effectively avoiding cutting and puncture effects. This achieves passive, physical anti-scratch protection, greatly reducing the risk of users being scratched during transportation, installation, and daily use. It also protects the surfaces of furniture, walls, and other items in contact with it from damage. The arc-shaped edge processing may have a microscopic effect on the overall rigidity of the profile. The buffer elastic strip 5 is made of flexible materials such as EPDM rubber and thermoplastic elastomer (TPE) and is fixed in the groove of the profile side wall through a snap-fit ​​structure or adhesive method at its bottom. When external force is applied, the buffer elastic strip 5 will first undergo elastic compression deformation. The deformation process absorbs some of the collision energy, providing soft cushioning and further improving the protective effect, effectively reducing the risk of pinching hands during installation.
