[0023] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0024] The present utility model is a mother-child type underground cable conduit, including: a main body 1, the head of which has a trapezoidal groove 11, and the tail of which has a trapezoidal protrusion 12 that cooperates with the trapezoidal groove 11 of the other main body 1; a positioning groove 13, which is opened on both sides of the main body 1 and is close to the tail and head of the main body 1; a positioning member 2, when the two main bodies 1 are assembled together, the two positioning grooves 12 form a chamber 14 for accommodating the positioning member 2;

[0025] In this solution, the head of the main body has a trapezoidal groove, and the tail has a trapezoidal protrusion. The trapezoidal protrusion can be pre-positioned by surface matching with the trapezoidal groove of another main body; the top of the trapezoidal groove is an opening, which is convenient for another main body to enter the trapezoidal protrusion through hoisting from the opening to match with the trapezoidal groove;

[0026] When the assembly is completed, the positioning member is snapped into the chamber to pre-connect the two main bodies, preventing them from moving in other directions, facilitating the subsequent sealing of the two main bodies, and realizing the rapid positioning of the underground cable conduit during the assembly process.

[0027] To illustrate the structure of the positioning groove 13, the present utility model adopts that the positioning groove 13 includes: a limiting groove 131; and a connecting groove 132, one end of which is connected to the limiting groove 131, and the other end extends to the tail or head of the main body 1; the width of the connecting groove 132 is smaller than the width of the limiting groove 131;

[0028] In this solution, after the two opposite positioning grooves are matched, the middle is narrow and the two ends are wide, which is convenient for cooperation with the positioning member.

[0029] To illustrate the structure of the positioning member, the present utility model adopts two limiting parts 21 connected by a connecting rod 22; wherein, the limiting part 21 is matched with the shape of the limiting groove 131, and the width of the connecting rod 21 is matched with the width of the connecting groove 132;

[0030] The middle of the positioning member is narrow and the two ends are wide, and it is in surface fit with the chamber; the connecting rod can be placed in the connecting groove.

[0031] To illustrate another structure of the positioning member, the positioning member 2 of the present utility model includes: two limiting portions 21 arranged oppositely; a through groove 23, and the through groove 23 is opened in one of the limiting portions 21 along its length direction; an insertion portion 24, and the other limiting portion 21 is provided with the insertion portion 24 inserted into the through groove 23; a wedge-shaped groove 25, which is opened at the insertion portion 24; a wedge-shaped block 26, which is arranged in the through groove 23 and is in surface fit with the wedge-shaped surface of the wedge-shaped groove 25; a locking member 27, which passes through the limiting portion 21, is threadedly connected with the limiting portion 21, and connects the end located in the through groove 23 with the wedge-shaped block 26; rotating the locking member 27 drives the wedge-shaped block 26 to move downward and drives the insertion portion 24 to move, so as to bring the two limiting portions 21 closer.
