However, there are some problems with the traditional embedded pipe fittings during installation and use, such as difficult installation, insufficient sealing performance, easy to fall off and difficult maintenance, etc., especially the traditional threaded installation structure. Due to the large amount of concrete or sand and other debris on the construction site, it will adhere to the thread. If the staff cannot completely clean up the debris, it will cause thread damage and affect the installation work. They can only break the concrete again to re-embed and dock, which not only increases the construction cost, but also affects the progress of the construction. Therefore, it is necessary to improve the structure of the embedded pipe fittings to improve its use effect and extend its service life. Utility Model Content

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0025] The utility model proposes a drainage embedded pipe fitting, during construction, the embedded body 1 is embedded in the hole opened in advance, then the soft rubber strip 2 is inserted into the T-slot, and the plugging plate 3 is buckled in the opening above the embedded body 1 to prevent concrete from entering during backfilling and affecting the later installation, and then the gap between the embedded body 1 and the hole is filled with concrete, and after the concrete solidifies, the soft rubber strip 2 and the plugging plate 3 are removed, the sealing gasket 10 is sleeved on the outer wall of the socket 6, and the socket 6 is inserted into the opening above the embedded body 1 and rotated to adjust the position , so that the elliptical bolt hole above the socket 6 is aligned with the T-slot 4, and when the pipeline is installed, there will be an error of 5-10mm. The relative position of the elliptical bolt hole and the T-slot can be changed to perform the centering operation. The cross-shaped protrusion is used to assist in the centering, and a gap is left below the outer wall of the socket 6 and above the inner wall of the embedded body 1 to prevent overflow. Then, the bolt assembly 5 passes through the elliptical bolt hole and the T-slot 4 and is tightened to make the sealing gasket 10 fill the gap between the socket 6 and the embedded body 1 to seal it. , then install the socket rubber ring 7 into the socket 6 and fit it with its inner wall, the annular protrusion on the outer wall of the socket rubber ring 7 fits with the annular groove on the inner wall of the socket 6 to play a pre-fixing role to prevent it from falling off, and then the pipe can be inserted into the socket rubber ring 7 for installation, so that the pipe and the socket rubber ring 7 fit tightly, and at the same time, protruding annular oblique ribs are provided on the inner wall of the socket rubber ring 7. After the pipe is inserted, it is squeezed and pressed against the inner wall of the socket rubber ring 7 to increase the friction, and when the pipe is subjected to an upward force, the annular oblique ribs will be lifted The more tightly fitting outer wall of the pipe further increases the friction by increasing the axial pressure, thereby preventing the pipe from falling off, and also increases the sealing performance between the pipe and the socket 6 to prevent overflow. The pipe rubber ring 9 is inserted under the inner wall of the embedded body 1, so that the annular protrusion on the outer wall fits with the annular groove of the embedded body 1 for pre-fixation, and then the pipe 8 is inserted into the pipe rubber ring 9, so that the outlet of the annular protrusion at the bottom of the embedded body 1 fits with the inner wall of the pipe 8. At this time, the pipe rubber ring 9 is squeezed to fill the gap for sealing.

[0026] The L-shaped water discharge outlet 11 arranged on one side of the embedded body 1 is an integral structure with the embedded body 1, and a detachable and replaceable flap 13 for preventing backflow and a grate 12 for filtering debris to prevent pipe clogging are installed at its entrance. When drainage on the same floor is required, the accumulated water is introduced into the embedded body 1 through the water discharge outlet 11 and discharged through the pipe 8.
