[0002] With the rapid development of social economy, a hollow aluminum tube is a kind of wall tube made of aluminum alloy, which has the characteristics of light weight, corrosion resistance, good thermal conductivity, etc. The commonly used aluminum alloy tubes have high material hardness, good tensile strength, and excellent corrosion resistance. They are often used in the manufacture of parts of aerospace spacecraft, automobile wheels, etc. Among them, most of the inner walls of the hollow aluminum tubes are solid, and some are hollow. The hollow inner wall of the aluminum tube needs to be welded with support ribs to support the hollow inner wall, so as to improve the overall strength of the hollow aluminum tube.

[0003] However, most of the support ribs in the inner wall of the existing hollow aluminum tubes are integral plate parts. This setting may make the overall strength of the hollow aluminum tube not high enough, resulting in small tensile and bending resistance strengths of the hollow aluminum tube.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 to 3 , an embodiment provided by the present utility model: a high-strength hollow aluminum tube, including an outer semi-circular tube A8, an outer semi-circular tube B9 is welded to one side of the outer semi-circular tube A8, and end shells 2 are fixedly connected to the front and rear ends of both the outer semi-circular tube A8 and the outer semi-circular tube B9. A protective film A1 is fixedly adhered to the surfaces of the outer semi-circular tube A8 and the outer semi-circular tube B9. This protective film A1 protects the outer surface of the hollow aluminum tube to prevent the outer surface from being oxidized and corroded. A plurality of reinforcing plate members 4 are welded and connected to the inner circumference of the outer semi-circular tube A8 and the outer semi-circular tube B9. An inner semi-circular tube A5 is fixedly connected to the inner sides of the plurality of reinforcing plate members 4. An inner semi-circular tube B6 is fixedly provided on one side of the inner semi-circular tube A5. A protective film B7 is adhered to the inner walls of the inner semi-circular tube B6 and the inner semi-circular tube B6. The protective film B7 protects the inner surface of the hollow aluminum tube to prevent its inner surface from being oxidized and corroded.

[0022] Furthermore, mating grooves 10 are provided at the upper and lower ends of both the outer semi-circular tube B9 and the inner semi-circular tube B6, and mating plates 11 are provided at the upper and lower ends of both the outer semi-circular tube A8 and the inner semi-circular tube A5. Then, the mating grooves 10 and the mating plates 11 are alternately arranged in a serrated shape. This arrangement enables the mating groove 10 on the outer semi-circular tube B9 and the mating plate 11 on the outer semi-circular tube A8 to be inserted and connected to each other, and the mating groove 10 on the inner semi-circular tube B6 and the mating plate 11 on the inner semi-circular tube A5 to be inserted and connected to each other. Among them, the mating grooves 10 and the mating plates 11 are alternately arranged in a serrated shape, and the mating grooves 10 and the mating plates 11 come into contact to form weld seams. This arrangement increases the contact area between the outer semi-circular tube B9 and the outer semi-circular tube A8, and also increases the contact area between the inner semi-circular tube B6 and the inner semi-circular tube A5. Furthermore, the weld seam between the outer semi-circular tube A8 and the outer semi-circular tube B9 is lengthened and the contact area is increased, and the weld seam between the inner semi-circular tube B6 and the inner semi-circular tube A5 is also lengthened and the contact area is increased. Finally, the welding between the outer semi-circular tube B9 and the outer semi-circular tube A8 is more firm, and the welding between the inner semi-circular tube B6 and the inner semi-circular tube A5 is also more firm. Then, the arrangement of the mating grooves 10 and the mating plates 11 indirectly strengthens the firmness of the hollow aluminum tube.

[0023] The cross-section of the above-mentioned reinforcing plate member 4 is set as a V-shaped structure. Then, the V-shaped reinforcing plate member 4 has a fixed connection effect on the overall inner semi-circular tube B6 and the outer semi-circular tube B9, and also enables a fixed connection between the inner semi-circular tube A5 and the outer semi-circular tube A8. Then, the reinforcing plate member 4 has a strong supporting effect on the external outer semi-circular tube A8 and the outer semi-circular tube B9, increasing the tensile and anti-bending strength of the overall aluminum tube.

[0024] Please refer to Figure 4 Figure 4 , another embodiment provided by the present utility model: the cross-section of the above-mentioned reinforcing plate member 4 can also be set as an M-shaped structure. The M-shaped reinforcing plate member 4 has a fixed connection effect on the overall inner semi-circular tube B6 and the outer semi-circular tube B9, and at the same time also enables a fixed connection between the inner semi-circular tube A5 and the outer semi-circular tube A8. A middle rib plate 12 is fixedly welded at the middle of the reinforcing plate member 4, and the middle rib plate 12 has a fixed supporting effect on the middle of the reinforcing plate member 4. Side rib plates 3 are fixedly welded on both sides of the reinforcing plate member 4, and the side rib plates 3 also have a fixed supporting effect on both sides of the reinforcing plate member 4. The setting of the side rib plates 3 and the middle rib plate 12 further enhances the tensile and anti-bending strength of the overall aluminum tube.
