[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-3 As shown, the utility model provides a luggage rack black anodized aluminum hanger, comprising:

[0031] The hanging frame 100 has an upper hanging rod 110 and a lower hanging rod 120 arranged in parallel, forming a stable frame and providing a basic platform for carrying the luggage rack;

[0032] The upper hook 130 is disposed on the upper hanging rod 110, the hanging end and the connecting end of the upper hook 130 are respectively located on the front and rear surfaces of the hanging frame 100, and the upper hook 130 is connected to the upper hanging rod 110 only through a single point so that the upper hook 130 has elasticity;

[0033] A lower hook 140, which is disposed on the lower hanging rod 120;

[0034] The upper and lower ends of the product are hung on the upper hook 130 and the lower hook 140 respectively, wherein the upper hook 130 gives the product downward elastic pressure, and the lower hook 140 gives the product upward supporting force.

[0035] It is worth mentioning here that when the product is hung, the upper hook 130 can use its own elasticity to provide continuous downward pressure, thereby ensuring that the luggage rack always maintains a close fit during the entire anodizing process, improving the reliability of contact conductivity, and the lower hook 140 provides an upward support force for the product, and cooperates with the upper hook 130. The double force ensures that the aluminum tube is firmly hung in the anodizing tank, avoiding production defects caused by shaking or falling off.

[0036] This type of hanger enhances the hanging stability of the product and achieves more stable current transmission, thereby improving the consistency of the anodizing effect, reducing the defect rate, and improving the overall production efficiency. This not only helps companies reduce cost losses, but also expands the company's business contracting capabilities and meets more market demands due to its efficient and stable characteristics.

[0037] Preferably, both the front and rear surfaces of the hanging frame 100 are hanging surfaces and can be used to hang products, which can fully utilize the space and process more automobile luggage rack aluminum tubes at the same time. This double-sided hanging design greatly improves the capacity utilization rate per unit volume and further improves production efficiency.

[0038] Preferably, the upper hanging rod 110 is provided with two groups of upper hooks 130 , which are distributed on the left and right sides of the upper hanging rod 110 , and the lower hanging rod 120 is provided with two groups of lower hooks 140 , which are distributed on the left and right sides of the lower hanging rod 120 .

[0039] The upper hook 130 located on the left side of the upper hanging rod 110 and the lower hook 140 located on the right side of the lower hanging rod 120 are located on the front side of the hanging frame 100 and are used to hang products; the upper hook 130 located on the right side of the upper hanging rod 110 and the lower hook 140 located on the left side of the lower hanging rod 120 are located on the back side of the hanging frame 100 and are used to hang products.

[0040] The advantage of this design is that it can better balance the stress on the product during the hanging process, so that a single product is not upright after hanging but in a certain tilted state. The tilted state helps the product to fully contact the electrolyte in all parts during the anodizing process, ensuring the uniformity of the oxidation treatment and avoiding quality problems such as incomplete oxidation or color differences caused by poor local contact.

[0041] Preferably, the upper hook 130 has multiple bends, wherein the bend at one of its hanging ends can be inserted into the empty groove at the upper end of the product to form a close abutting contact with the product. Combined with the single-point connection structure between the upper hook 130 and the upper hanging rod 110, the purpose of giving the upper hook 130 elastic deformation ability is achieved. The realization of the elastic function, on the one hand, can adapt to product sizes of different specifications or slight deviations, automatically adjust through elastic deformation, tightly press the product, and prevent the product from falling off the hanger due to shaking during the anodizing process; on the other hand, moderate elastic pressure can also ensure good conductive contact between the product and the hanger, which is conducive to the uniform passage of current, thereby improving the quality and consistency of anodizing, reducing the defective product rate, and improving production efficiency.

[0042] Preferably, a supporting groove 141 is provided at the hanging end of the lower hook 140, and the lower end of the product is embedded in the supporting groove 141 to provide a stable supporting force, significantly improving the hanging stability, while also increasing the contact area and contact tightness with the hanger, thereby improving the conductivity and ensuring uniform and stable current transmission during the anodizing process, which helps to improve the quality and consistency of the oxide film.

[0043] Preferably, a vertically arranged support rod 150 is also connected between the upper hanging rod 110 and the lower hanging rod 120 to improve the structural strength and stability of the entire hanging frame 100, ensuring that the hanger is not easily deformed or twisted when multiple automobile luggage rack aluminum tubes are mounted, and effectively preventing problems such as product falling off or poor conductivity caused by the instability of the hanger itself.
