Detailed Description

The invention will be further described in the following with specific embodiments in conjunction with the drawings, see fig. 1:

a quick connector of a water pipe comprises a connector tube 1, wherein the upper end of the connector tube 1 is provided with a quick insertion device 2, the quick insertion device 2 comprises a pressing tube seat 20, a pressing tube 21, a clamping ring 22 with clamping jaws 220 and a supporting ring 23, the lower end of the pressing tube seat 20 abuts against the upper end of the connector tube 1, a lower shoulder 201 and an upper shoulder 202 are sequentially formed in the pressing tube seat 20 from bottom to top, the outer wall of the pressing tube 21 is formed with a pressing tube ring 210 used for being clamped with the upper shoulder 202, the upper end face of the clamping ring 22 abuts against the lower end face of the lower shoulder 201, the upper end face of the supporting ring 23 abuts against the lower end face of the clamping ring 22, a sliding groove 200 is formed between the upper shoulder 202 and the lower shoulder 201, the pressing tube ring 210 slides up and down along the sliding groove 200, when the pressing tube ring 210 slides up and down, the clamping jaws 220 are opened from closing, the outer wall of the pressing tube seat 20 is formed with an upper convex ring 203, and the outer wall of the connector tube 1, the outer wall of the pressing cylinder seat 20 is sleeved with a metal ring sleeve 3, and the upper end and the lower end of the metal ring sleeve 3 are respectively clamped with the upper convex ring 203 and the lower convex ring 10.
