[0047] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0048] Refer to Figures 1 - 3, an embedded conduit, comprising: an embedded elbow 11, a horizontal pipe 19, a vertical pipe 12, a connecting pipe 23, an insertion block 24, a limiting rod 26, a spring 27, a support plate 16, a reinforcement plate 17, a positioning plate 14, and a reinforcing rib 13.

[0049] The embedded elbow 11 is an elbow with a circumferential angle of 45°. The horizontal pipe 19 is fixedly connected to the embedded elbow 11, and the vertical pipe 12 is fixedly connected to the embedded elbow 11. A plurality of reinforcing ribs 13 are provided and fixedly connected to the embedded elbow 11 at equal intervals. One end of the reinforcing rib 13 is fixedly connected to the end wall of the horizontal pipe 19, and the other end of the reinforcing rib 13 is fixedly connected to the end wall of the vertical pipe 12. The support plate 16 is fixedly connected to the horizontal pipe 19, the reinforcement plate 17 is fixedly connected to the support plate 16. A first positioning hole 18 is provided on the support plate 16. The support plate 16 is an L-shaped plate. A part of the reinforcement plate 17 is fixedly connected to the support plate 16, and the upper end of the reinforcement plate 17 is fixedly connected to the arc-shaped outer wall of the horizontal pipe 19. The positioning plate 14 is fixedly connected to the vertical pipe 12, and a second positioning hole 15 is provided on the positioning plate 14.

[0050] Two symmetrically positioned slots 20 are provided on the horizontal pipe 19. A rotating groove 21 is provided on the groove wall of the slot 20. The rotating groove 21 extends circumferentially around the axis of the horizontal pipe 19 and is an annular groove. A plurality of limiting holes 22 are provided on the arc-shaped outer wall of the horizontal pipe 19 and the limiting holes 22 communicate with the rotating groove 21.

[0051] Internal threads are provided on the inner diameter surface of the connecting pipe 23. The connecting pipe 23 is rotatably connected inside the horizontal pipe 19. Two insertion blocks 24 are provided and symmetrically fixedly connected to the connecting pipe 23. A plurality of guiding grooves 25 are provided on the insertion block 24 at equal intervals. A plurality of limiting rods 26 are provided and respectively slidably connected in each guiding groove 25. A spherical guiding surface 28 is provided on the end wall of the limiting rod 26. A plurality of springs 27 are provided. One end of the spring 27 is fixedly connected to the groove wall of the guiding groove 25, and the other end of the spring 27 is fixedly connected to the end wall of the limiting rod 26. The insertion block 24 is inserted into the slot 20 and the insertion block 24 is located inside the rotating groove 21.

[0052] During work or installation:

[0053] Initial state: The connecting pipe 23 is disconnected from the horizontal pipe 19, and the end of the limiting rod 26 provided with the spherical guiding surface 28 extends out of the guiding groove 25;

[0054] Place the support plate 16 and the positioning plate 14 on the ground so that the vertical pipe 12 is aligned with and connected to the vertical wiring pipe on the ground. Insert bolts or screws into the first positioning hole 18 and the second positioning hole 15 and fix the support plate 16 and the positioning plate 14 to the ground or the wall through the bolts or screws. Sleeve the connecting pipe 23 onto the horizontal wiring pipe and rotate the connecting pipe 23 so that the connecting pipe 23 is threadedly connected to the horizontal wiring pipe. Press down the spherical guide surface 28 to make the limiting rod 26 move downward and completely contract and slide into the guide groove 25. Then align the connecting pipe 23 and the insertion block 24 with the slot 20 on the horizontal pipe 19, push the connecting pipe 23 and make the connecting pipe 23 and the insertion block 24 move along the extension direction of the slot 20 until the insertion block 24 abuts against and contacts the wall of the rotating groove 21. Then rotate the connecting pipe 23, the connecting pipe 23 drives the insertion block 24 to rotate, and the insertion block 24 drives the plurality of limiting rods 26 to rotate (and during this process, the wall of the rotating groove 21 abuts against and contacts the spherical guide surface 28, and the spring 27 is still in a compressed state). When the insertion block 24 drives the limiting rod 26 to rotate until the axis of the limiting rod 26 is the same as the extension direction of the axis of the limiting hole 22, the wall of the rotating groove 21 no longer abuts against the spherical guide surface 28. At this time, the spring 27 releases its elastic potential energy and pushes the limiting rod 26, so that the limiting rod 26 quickly extends out of the guide groove 25 and inserts into the limiting hole 22. By the limitation of the limiting hole 22 on the limiting rod 26, the connecting pipe 23 cannot rotate and be pulled out of the horizontal pipe 19, thus completing the connection and fixation of the horizontal wiring pipe to the connecting pipe 23 and the horizontal pipe 19 respectively.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
