Detailed Description

In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, or may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, the meaning of "plurality" or "a plurality" is two or more unless otherwise specified.

Please refer to fig. 1 to 4, fig. 1 to 4 disclose a pipe quick connector easy to assemble and disassemble, which includes a connector body 1 and a gland 2 cooperatively connected with the connector body 1, one side of the gland 2 is funnel-shaped, a first supporting pad 3, a gasket 4, a first sealing ring 51 and a second sealing ring 52 are arranged in the gland 2, one end of the first supporting pad 3 abuts against the connector body 1 through the first sealing ring 51, the other end of the first supporting pad 3 abuts against the gasket 4 through the second sealing ring 52, the gasket 4 is formed by combining at least two arc gasket blocks 41 in a manner of being bound by an elastic member 42, the inner wall of the gasket 4 is provided with a second annular groove 20 matched with a convex ring 91 on a pipe body 9, in the invention, the connector body 1 is provided with a first connecting lug 11 with threads (as shown in fig. 4), the gland 2 is provided with a second connecting lug 21 with threads, and the connection between the connector body 1 and the gland 2 is realized by connecting the first connecting lug 11 with the second connecting lug 21 through a screw rod 6; in the invention, the outer wall of the gasket 4 is provided with a first annular groove 40 surrounding the gasket 4 and used for accommodating the elastic piece 42, and the elastic piece 40 binds the arc-shaped gasket block 41 by surrounding along the first annular groove 40; when the pipe joint is used and a connecting pipe joint needs to be disassembled for maintenance or repair, the screw rod 6 between the gland 2 and the connecting joint body 1 is loosened, the connection between the gland 2 and the connecting joint body 1 is loosened, at this time, because the port 90 of the pipe body is always flush with the port 10 of the connecting joint body on the same side or always positioned outside the connecting joint body 1, the connecting joint body 1 can be directly disassembled, then the first supporting pad 3, the first sealing ring 51 and the second sealing ring 52 in the gland 2 are taken out, and the elastic piece 42 binding the gasket 4 is loosened, so that the gasket 4 is scattered to form a plurality of arc gasket blocks 41.
