Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, specifically relating to a bending-resistant aluminum profile. Background Technology

[0002] Aluminum profiles are widely used in construction, machinery manufacturing, and transportation due to their advantages such as light weight, high strength, and corrosion resistance. In practical applications, aluminum profiles often need to withstand a certain amount of bending force, therefore their bending resistance is an important indicator of product quality.

[0003] Problems with existing technology:

[0004] Current aluminum profiles have limited bending resistance and are prone to deformation when subjected to large external forces. To ensure strength, the amount of material used is often increased, leading to increased costs and weight. In addition, unreasonable structural design results in uneven stress distribution and local damage. Utility Model Content

[0005] The purpose of this invention is to provide a bending-resistant aluminum profile that can improve overall strength while reducing material usage through a hollow design, thus achieving a balance between lightweight and high strength.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A bending-resistant aluminum profile, comprising:

[0008] Core;

[0009] A reinforcing core is arranged concentrically with the core body on the outside of the core body;

[0010] Four corner plates are equidistantly arranged around the reinforcing core. The two sides of the corner plates have a teardrop-shaped cross-section, and both ends of the corner plates are provided with waist holes.

[0011] A connecting plate that connects to the reinforcing core is provided at the corner of the corner plate.

[0012] The two sides of the corner plate are of the same length and are perpendicular to each other.

[0013] Multiple reinforcing plates are equidistantly arranged along the circumferential direction between the core and the reinforcing core, and the thickness of the reinforcing plates is 1.5-2mm.

[0014] An arc-shaped plate is provided on the outer wall of the reinforcing core and between the two connecting plates, and the two ends of the arc-shaped plate are respectively fixed to two adjacent corner plates.

[0015] A reinforcing ring is fixed to the middle of one side of the connecting plate and is fixed to the outer wall of the two adjacent arc-shaped plates.

[0016] The inner side of the core and the outer side of the arc plate are both provided with multiple reinforcing ribs at equal intervals along the circumference.

[0017] The technical effects achieved by this utility model are as follows:

[0018] The corner plates of this invention are evenly distributed around the reinforcing core. The two sides are vertical and the cross-section is teardrop-shaped. The teardrop-shaped structure can disperse external forces and enhance the bending resistance of the sides. The waist holes at both ends further optimize the stress distribution and reduce the risk of deformation of the corner plates under stress.

[0019] The arc-shaped plate in this invention connects adjacent corner plates and cooperates with the reinforcing core to form a ring-shaped support structure surrounding the reinforcing core. This structure can disperse radial and axial forces from the outside, enhancing the torsional and bending resistance of the aluminum profile.

[0020] The core and reinforcing core of this utility model adopt a concentric ring structure design, which, together with the reinforcing plate between them, forms a double-layer stress structure. While improving the overall strength, the hollow design reduces the amount of material used, achieving a balance between lightweight and high strength. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-2 As shown, a bending-resistant aluminum profile includes:

[0027] Core 1;

[0028] The reinforcing core 3 is arranged concentrically with the core body 1 outside the core body 1. Multiple reinforcing plates 2 are equidistantly arranged between the core body 1 and the reinforcing core 3 along the circumferential direction. The thickness of the reinforcing plates 2 is 1.5-2mm.

[0029] According to the above structure, the cross-sections of the core 1 and the reinforcing core 3 are circular rings, and the core 1 and the reinforcing core 3 are arranged in concentric circles, which enhances the overall strength of the aluminum profile. At the same time, it reduces the amount of material used while ensuring strength, thus achieving efficient use of materials. Combined with the reinforcing plate 2, it further improves the structural strength and bending resistance of the aluminum profile.

[0030] Four corner plates 5 are equidistantly arranged around the reinforcing core 3. The two sides of the corner plates 5 have teardrop-shaped cross sections. Both ends of the corner plates 5 are provided with waist holes 7. The two sides of the corner plates 5 are of the same length and perpendicular to each other, so that they can bear external forces more evenly. A connecting plate 4 connected to the reinforcing core 3 is provided at the corner of the corner plate 5. An arc plate 6 is provided on the outer wall of the reinforcing core 3 between the two connecting plates 4. The two ends of the arc plate 6 are fixed to the two adjacent corner plates 5 respectively. A reinforcing ring 8 is fixed to the middle of one side of the connecting plate 4 and is fixed to the outer wall of the two adjacent arc plates 6.

[0031] According to the above structure, the two sides of the corner plate 5 are teardrop-shaped, which improves the strength of the two sides of the corner plate 5. The waist hole 7 improves the strength and bending resistance of the two sides of the corner plate 5, and can better cope with the external force. The arc plate 6 makes the reinforcing core 3, the connecting plate 4 and the corner plate 5 form a coherent force-bearing structure, which disperses the external force and enhances the bending resistance and overall stability of the aluminum profile.

[0032] Multiple reinforcing ribs are equidistantly arranged along the circumference on the inner side of the core 1 and the outer side of the arc plate 6. By increasing the thickness and strength of the local structure, the bending resistance of the core 1 and the arc plate 6 is further enhanced, thereby improving the overall bending resistance and structural stability of the aluminum profile.

[0033] The working principle of this utility model is as follows: The core 1 and the reinforcing core 3 adopt a concentric circular ring structure design, which, together with the reinforcing plate 2 between them, forms a double-layered stress-bearing structure. While improving the overall strength, the hollow design reduces the amount of material used, achieving a balance between lightweight and high strength. The reinforcing plate 2 is evenly distributed along the circumference, with a thickness controlled between 1.5-2mm. This ensures the connection stability between the core 1 and the reinforcing core 3, and can evenly transfer external forces to the entire structure, avoiding local stress concentration and significantly improving the bending resistance of the aluminum profile. The corner plates 5 are evenly distributed around the reinforcing core 3, with vertical sides and a teardrop-shaped cross-section. The teardrop-shaped structure can disperse external forces and enhance the side bending resistance. The waist holes 7 at both ends further optimize the stress distribution and reduce the risk of deformation of the corner plates 5 under stress. Plate 4 connects corner plate 5 and reinforcing core 3, enabling the force of corner plate 5 to be effectively transferred to reinforcing core 3, preventing corner plate 5 from becoming disconnected from the main structure, and improving the overall structural load-bearing capacity. Arc-shaped plate 6 connects adjacent corner plates 5 and cooperates with reinforcing core 3 to form a ring support structure around reinforcing core 3, which can disperse radial and axial forces from the outside and enhance the torsional and bending resistance of the aluminum profile. Reinforcing ring 8 connects multiple arc-shaped plates 6 into a whole, making the force on the arc-shaped plates 6 more uniform and preventing individual arc-shaped plates 6 from being damaged due to excessive force, further improving structural stability. The reinforcing ribs on the inner side of core 1 and the outer side of arc-shaped plates 6 increase the stiffness of the local structure, thereby enhancing the internal pressure deformation resistance of core 1 and the external pressure deformation resistance of arc-shaped plates 6, respectively, thus improving the overall bending resistance of the aluminum profile.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
