[0002] A right angle joint is usually composed of an upper pipe, a lower pipe and an elbow joint. Its function is to connect two sections of pipes that form a right angle so that the fluid can flow along the direction of the pipe.

[0003] There are some problems with the existing right-angle adjustable joints on the market, mainly in terms of stability. First, at the elbow joint, the fluid is usually affected by turbulence and eddy currents, which impact the bends of the elbows, causing fluid instability and possibly causing vibration and noise in the piping system. Turbulence and eddy currents may also accelerate the wear of the inner wall of the elbow joint, resulting in more frequent maintenance and replacement of the joints.

[0004] Therefore, a right-angle joint is urgently needed to solve the technical defects proposed in the above technology. Utility Model Content
