Description
Technical field
This practical adpting flange belongs to Heating,Ventilating and Air Conditioning (HVAC) industry, is a kind of adpting flange for Central air-conditioning unit equipment ventilation duct.
Background technique
At present, conventional rack flange be general steel plate through cutting, punching, chamfer, bending, welding, polishing, spraying coating process make, the flow process that there is technique is complicated, make long, the shortcoming such as cost of material is high in man-hour.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and propose a kind of can the ventilation duct adpting flange of independent assortment different size for Central air-conditioning unit equipment.
Main technical schemes of the present utility model: can the ventilation duct adpting flange of independent assortment different size, it is characterized in that it comprises the square flange be made up of two group aluminum alloy section bars, two groups of interlaced collocation of section bar form adpting flange, wherein one group of section bar is provided with attachment hole, another group section bar is provided with screw circular hole, passes through self-drilling connection between two groups of section bars.
The thickness of described two group aluminum alloy section bars is 2mm.
Described two group aluminum alloy section bars have anodizing film, thickness rank AA15.
The utility model can directly draw flange frame shape with aluminum alloy material, by cutting, punching, assembled.Reduce technological process, save man hour of labour and not easily get rusty.
The advantage of the utility model product: fabrication processing is few, labor hour is few, not easily gets rusty, and makes precision and improves.
