Description

Technical Field

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

[0002] Aluminum profiles are widely used in industrial equipment protection, building decoration, and home edging due to their lightweight, corrosion resistance, and ease of processing. However, existing aluminum profile protection structures still have significant shortcomings in terms of lightweighting, impact resistance, ease of installation, and multi-functional integration. For example, traditional aluminum profiles are usually designed as solid or thick-walled to increase load-bearing capacity, resulting in excessive weight and increased transportation and installation costs. If a thin-walled hollow structure is used, it is prone to collapse or deformation due to uneven local stress, making it difficult to meet the high-strength requirements of industrial equipment protection. Utility Model Content

[0003] The main purpose of this utility model is to provide a lightweight hollow aluminum profile that maintains high structural strength while being lightweight.

[0004] To achieve the above objectives, this utility model provides a lightweight hollow aluminum profile, which includes an aluminum profile body with a hollow cross-section and a wall thickness of 0.8mm to 2.5mm. The hollow structure contains intersecting transverse and longitudinal reinforcing ribs forming a grid-like support frame. The upper surface of the aluminum profile body has an arc-shaped protrusion covered with an elastic buffer layer. The bottom of the aluminum profile body has a detachable mounting base plate connected to the aluminum profile body via a snap-fit ​​structure. Multiple sets of magnetic adsorption blocks are embedded at intervals on the lower surface of the mounting base plate. Both ends of the aluminum profile body have sealing end caps filled with a sound-absorbing cotton layer.

[0005] This utility model provides a lightweight hollow aluminum profile. The grid-like cross-reinforcing rib design improves compressive strength, while the wall thickness of 0.8-2.5mm achieves weight reduction. The arc-shaped protrusions disperse impact force, and the elastic buffer layer (such as polyurethane) absorbs the remaining energy, improving impact resistance. Thus, the lightweight hollow aluminum profile provided by this utility model maintains high structural strength while being lightweight. At the same time, the magnetic adsorption block enables glue-free and rapid installation, improving disassembly and maintenance efficiency.

[0006] In one possible implementation, the thickness of the transverse and longitudinal stiffeners is 1 / 4 to 1 / 3 of the wall thickness of the aluminum profile body. The spacing between adjacent transverse stiffeners is 10mm to 20mm, and the spacing between adjacent longitudinal stiffeners is 15mm to 30mm. The stiffener thickness of 1 / 4 to 1 / 3 of the wall thickness balances support efficiency and lightweight design, avoiding excessive weight increase. The spacing range of the longitudinal stiffeners is compatible with standard extrusion molding processes, reducing processing difficulty and cost.

[0007] In one possible implementation, the elastic buffer layer is made of silicone or polyurethane, with a thickness of 1mm to 3mm, and the surface of the elastic buffer layer has anti-slip textures. Silicone / polyurethane is resistant to aging and ultraviolet rays, extending its service life.

[0008] In one possible implementation, the magnetic adsorption blocks are neodymium iron boron magnets arranged in a rectangular array, with each magnet measuring 5mm × 5mm × 2mm and the spacing between adjacent magnets ranging from 8mm to 12mm. The neodymium iron boron magnets provide a high magnetic energy product, and the optimized size and spacing of each block ensure a uniform distribution of the adsorption force.

[0009] In one possible implementation, a waterproof strip is provided on the outer side of the sealing end cap, and the waterproof strip is interference-fitted with the end face of the aluminum profile body. The waterproof strip prevents moisture and dust from entering the hollow structure, extending the life of the aluminum profile. Attached Figure Description
