Description

Technical Field

[0001] The utility model belongs to the technical field of joints and relates to an elbow joint. Background Art

[0002] A joint is a component used to connect water pipes. Water pipe joints can be divided into: external threaded end-type water pipe joints, ferrule-type water pipe joints, and self-fixing water pipe joints according to their usage. External threaded end-type water pipe joints are die-cast with zinc alloy materials, and the surface is galvanized, frosted, or chrome-plated; they have a tight structure, no pores, and high strength. The ferrule-type water pipe joint can connect unthreaded steel pipes to hoses, eliminating the threading process and only requires screwing in; they have a tight structure and high strength. Existing joints are connected to external water pipes. When in use, because the liquid entering the pipe contains impurities, if a large amount of impurities enters the elbow joint, it will cause blockage, thereby affecting the water output efficiency of the pipe.
