Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, specifically to an oxidation-resistant and corrosion-resistant aluminum alloy profile. Background Technology

[0002] Aluminum alloy profiles are profiles made from aluminum and its alloys as the base material, processed into various cross-sectional shapes through extrusion, stretching and other processes;

[0003] For example, China Utility Model provides a patent for "an aluminum alloy profile with good corrosion resistance" (patent number: 202022370695.X). This patent includes a profile body, which includes a base layer. An inner protective part is fixedly connected to the inner side of the base layer. The inner protective part includes a first corrosion-resistant layer. A first anti-oxidation layer is electroplated at the bottom of the first corrosion-resistant layer and on the surface of the base layer. This can effectively improve the corrosion resistance of the profile body and also improve the anti-oxidation, sound insulation, heat insulation and waterproof performance of the profile body.

[0004] Although the aforementioned document has solved the problem that the natural oxide film on the surface of existing aluminum alloy profiles is easily corroded, thus greatly reducing their service life, it still has the disadvantages of simple support structure, low connection support strength, poor stress support effect, and high probability of deformation. Therefore, an oxidation-resistant and corrosion-resistant aluminum alloy profile is introduced here. Utility Model Content

This utility model uses a first positioning plate, a second positioning plate, a special-shaped reinforcing frame, a connecting plate, a slanted panel, a trapezoidal frame, and a circular anti-pressure sleeve to set anti-pressure components between four L-shaped frames. Several anti-pressure components form a high-strength anti-pressure structure, which enables the aluminum alloy profile formed by the four L-shaped frames to resist external pressure and not be easily squeezed and deformed by external forces.

[0014] 2. This utility model enhances the tensile strength, compressive strength, and rigidity of aluminum alloy by combining carbon fiber with a reinforcing layer, a heat insulation layer, and a protective layer.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides an oxidation-resistant and corrosion-resistant aluminum alloy profile, including an L-shaped frame 1. A first positioning plate 2 is fixedly connected to the inner wall of the L-shaped frame 1. A second positioning plate 3 is fixedly connected to the inner wall of the L-shaped frame 1 at a position away from the first positioning plate 2. A special-shaped reinforcing frame 4 is fixedly connected between the first positioning plate 2 and the second positioning plate 3. A connecting plate 5 is fixedly connected between the L-shaped frames 1. A sloping panel 6 is fixedly connected to one side of the connecting plate 5.

A protective layer 104 is fixedly connected to the outer surface of the heat insulation layer 103. Pressure-resistant components are set between the four L-shaped frames 1. Several pressure-resistant components constitute a high-strength pressure-resistant structure, enabling the aluminum alloy profile composed of the four L-shaped frames 1 to resist external pressure.

[0023] This technical solution utilizes a first positioning plate 2, a second positioning plate 3, a special-shaped reinforcing frame 4, a connecting plate 5, a slanted panel 6, a trapezoidal frame 7, and a circular anti-compression sleeve 8. By setting an anti-compression structure inside the aluminum alloy profile, the aluminum alloy profile can resist external pressure and is not easily deformed by compression. Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figures 1-3As shown, a pressure-resistant plate is fixedly connected to the inner wall of a circular pressure-resistant sleeve 8, and a positioning rod is fixedly connected between the pressure-resistant plates.

The material of the first component layer 1031 is ceramic fiber, and the material of the second component layer 1032 is PVC heat insulation strip.

[0025] The above technical solution is mainly adopted to increase the compressive strength of the circular compression sleeve 8 and improve the thermal insulation performance of the aluminum alloy profile. The compression plate and positioning rod form a triangular support frame, which can greatly improve the compressive strength of the circular compression sleeve 8, thereby improving the compressive strength of the aluminum alloy profile. Ceramic fiber has good high temperature resistance and is often used in aluminum alloy profiles in special industries. Ceramic fiber materials can effectively prevent heat transfer and are corrosion resistant. PVC thermal insulation strips have good UV resistance and strong chemical stability.

Specifically, by combining carbon fiber with aluminum alloy, its tensile strength, compressive strength, and rigidity are enhanced.

Ceramic fiber materials can effectively prevent heat transfer and are corrosion resistant. PVC heat insulation strips have good UV resistance and strong chemical stability. They are usually used for heat insulation between aluminum alloy window frames and glass to help reduce heat conduction.
