Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1-3, a pipe joint waterproof device comprises pre-buried pipes 1 and connecting members 2 for connecting the pre-buried pipes 1, wherein the connecting members 2 are provided with connecting pipes 3 at the butt ends of the pre-buried pipes 1, the connecting pipes 3 are inserted into the butt pipes at one ends of the pre-buried pipes 1,

the inside all movable mounting of both sides of connecting pipe 3 has location hook 4, and the outside of butt joint pipe is equipped with the hook groove 5 corresponding with location hook 4.

Referring to fig. 2 and 3, a plurality of groups of concentric annular rings are arranged at two ends of the embedded pipeline 1 and are correspondingly inserted into an annular groove arranged at one end of the connecting pipe 3.

Referring to fig. 2, the positioning hook 4 includes a hook and an extrusion plate, the hook is installed at the front end of the extrusion plate, and a rotating shaft is provided between the hook and the extrusion plate.

Referring to fig. 3, after the embedded pipeline 1 is inserted into the connecting pipe 3, the front end of the positioning hook 4 is inserted into the hook groove 5 outside the butt joint pipe, and the annular ring at one end of the embedded pipeline 1 is inserted into the annular groove at one end of the connecting pipe 3.

Referring to fig. 2, the inner wall of the connecting pipe 3 is provided with a notch for receiving and releasing the hook.

Referring to fig. 4, the outer portion of the embedded pipeline 1 is sleeved with a joint outer pipe 6, and a connection layer 7 is arranged between the inner wall of the joint outer pipe 6 and the outer wall of the embedded pipeline 1.

Referring to fig. 4, the outer portion of the joint outer tube 6 is uniformly provided with positioning grooves with T-shaped cross sections.
