Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings, wherein for convenience of description, the upper, lower, left, right, front, rear, and other orientations may be defined in the present application, which are intended to clearly describe the relative position relationship of the structures, and are not intended to limit the actual orientation of the product during the production, use, sale, and the like. The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

referring to fig. 1 to 4, the present embodiment provides a quick pipe joint, which includes a joint pipe, two locking handles (locking devices), and a sealing ring 30, where the joint pipe includes a sealing portion 11 and two connecting ends, one of the connecting ends is a female connecting end 12, and the other is a male connecting end 13, the sealing portion 11 is disposed between the two connecting ends, and two ends of the sealing portion 11 are respectively connected to the two connecting ends. The locking handle comprises a handle part 21 and a locking part 22, the locking part 22 is a cam, and one end of the handle part 21 is connected with the locking part 22.

Two handle mounting positions are arranged on the side wall of the female connecting end 12 in a penetrating manner, the two locking handles are rotatably mounted in the handle mounting positions through the locking parts 22, and the locking parts 22 are embedded into or separated from the female connecting end 12 under the control of the handle parts 21. The male connection end 13 has an outer diameter less than or equal to the inner diameter of the female connection end 12 and is nestably mounted in the female connection end 12. A locking groove 131 (locking auxiliary device) is concavely disposed on the side wall of the male connection end 13, and the locking groove 131 is disposed around the outer side wall of the male connection end 13.
