Aluminum alloy smooth rabbet

Abstract

The invention discloses an aluminum alloy smooth rabbet. The aluminum alloy smooth rabbet comprises first grooves, first fixing blocks, connecting pieces, a first connecting plate, a second connectingplate, a third connecting plate, second fixing blocks, second grooves, a fourth connecting plate, a fixing plate, limiting plates and a fifth connecting plate. According to the aluminum alloy smoothrabbet, the connecting plates, the fixing blocks and the fixing plate are all made of aluminum alloys, in the using process, the physical properties of the connecting plates, the fixing blocks and thefixing plate are the same, and thus no large gaps are generated; components in the smooth rabbet are connected in a 45-degree diagonal mode, connecting is convenient, in the using process, attractiveness and elegance are achieved, and the manufacturing cost is lowered; internal accessories are less, the excessively much accessories are not needed to be used in the mounting process, mounting is facilitated, the time and labor are saved, the working efficiency of people is improved, and the mounting cost is lowered; and the perfect shape of a window frame is ensured, in the using process, exposed notches are avoided, and the using safety of people is ensured.

Description

technical field [0001] The invention relates to an optical fiber, in particular to an aluminum alloy optical fiber, which belongs to the technical field of aluminum alloy applications. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. At present, aluminum alloy is the most widely used alloy. Doors and windows are divided into door frame and window. The light and hook are installed vertically on the window. The middle two of ordinary sliding windows are hooks, and the light is near the door frame. [0003] When using aluminum alloy light fittings, the light fittings of some doors and w...

AI Technical Summary

Problems solved by technology

[0003] When using aluminum alloy light fittings, the light fittings of some doors and windows are not composed of one material. Due to temperature changes, the expansion and contraction of different materials is different, resulting in cracks in the light fittings; when producing light fittings, the components inside the light fittings adopt right-angle Welding is not beautiful during use and increases manufacturing costs; some optical companies have too many internal accessories, which require a lot of time during installation, which is inconvenient to install, and too many accessories increase the cost; After the installation, the gap is exposed. When people use it, the gap is easy to scratch the human body, which is not conducive to people's use safety.
