Pipe Joint Structure
20170051853 · 2017-02-23 ·

A pipe joint structure contains: a body, a connection ring, and a screwing nut. The body includes a hollow channel defined therein, a connecting tube surrounding around the hollow channel and having at least one open end, and a coupling section arranged adjacent to an end portion of an outer wall of the connecting tube. The connection ring includes an inner joining diameter for connecting with the coupling section. The screwing nut includes an internal orifice, an outer diameter of which is greater than the body and the connection ring. The internal orifice has first inner threads formed around inner wall thereof and has a limiting rib arranged on one end of the internal orifice facing to the body, wherein an outer diameter of the internal orifice is greater than an outer diameter of the body and is smaller than an outer diameter of the connection ring.
