Press-fitting pipe connector with toothed ring

A press-fitting pipe connector with a toothed ring, comprising:

• a pipe joint (1), a sealing ring (2) and a pipe (5), wherein the pipe joint (1) is a “-”-like round pipe with equal wall thickness, an annular groove segment (1a) is disposed in a middle portion of the pipe joint (1), a conical pipe (1b), a round pipe segment (1c), a sealing ring protrusion ring segment (1d) and a shrinking clamping mouth (1f) are disposed at both ends of the annular groove segment (1a) in sequence, a protrusion ring assembly segment (1e) for assembling a toothed clamping ring (3) and a bushing (4) is added between the sealing ring protrusion ring segment (1d) and the shrinking clamping mouth (1f), a sealing ring (2), the toothed clamping ring (3) and the bushing (4) are assembled in parallel in inner cavities of the sealing ring protrusion ring segment (1d) and the protrusion ring assembly segment (1e) of the toothed clamping ring (3) and the bushing (4), a fitting end of the pipe (5) is run through inner diameters of the shrinking clamping mouth (1f), the bushing (4), the toothed clamping ring (3), the sealing ring (2), the round pipe segment (1c) and the conical pipe (1b) to the annular groove segment (1a), a radial pressure is applied by a press-fitting tool along outer diameters of the round pipe segment (1c), the sealing ring protrusion ring segment (1d) and the protrusion ring assembly segment (1e) of the toothed clamping ring (3) and the bushing (4), and the round pipe segment (1c), the sealing ring protrusion ring segment (1d) and the protrusion ring assembly segment (1e) of the toothed clamping ring (3) and the bushing (4) change from a round pipe shape into a neck shape under the action of the pressure.
