The electric bottom box is a box for placing electric elements, is generally embedded in a wall, and is generally arranged in a way that the electric bottom box cannot be seen from the outside. The wall body is formed by defining a pouring space through two steel mesh molds which are arranged oppositely, pouring wall body slurry into the pouring space, and forming the wall body after the wall body slurry is solidified. In order to install the electric bottom box, a groove for installing the electric bottom box needs to be drilled on the wall, the process not only increases the construction difficulty, but also damages the wall.

As shown in fig. 3, after the electric bottom box pre-buried mold 100 is installed and the electric bottom box 400 is inserted into the through hole 11 of the substrate 10, the wall slurry 300 is poured into the limited space between the two steel mesh molds 200, the bottom of the electric bottom box 400 can contact with the wall slurry 300, and when the wall slurry 300 is semi-solidified (initially solidified), the electric bottom box pre-buried mold 100 can be removed from the steel mesh molds 200, so that the mold can be reused.

The first limiting portion 20 can be bent relative to the substrate 10 to enable the first limiting portion 20 to be located at a first position and a second position, and the second limiting portion 30 can be bent relative to the substrate 10 to enable the second limiting portion 30 to be located at the first position and the second position. When the first limiting part 20 and the second limiting part 30 are both located at the first position, the first limiting part 20, the second limiting part 30 and the substrate 10 are coplanar; when the first and second defining portions 20 and 30 are located at the second position, the first and second defining portions 20 and 30 can cooperate to clamp the electric box inserted into the through-hole 11. The first limiting part 20 and the second limiting part 30 can be located at a first position or a second position through bending, when the first limiting part 20 and the second limiting part 30 are located at the first position, the first limiting part 20, the second limiting part 30 and the substrate 10 are coplanar, and the electric bottom box pre-buried mold 100 can occupy a small space; during actual construction, the first limiting portion 20 and the second limiting portion 30 are located at the second position, so that the first limiting portion 20 and the second limiting portion 30 clamp the electric bottom box.

The substrate 10 is a rectangular plate, the first preset direction a is the length direction of the substrate 10, the through hole 11 is a rectangular hole formed in the substrate 10, the rectangular hole has a first hole wall 111, a second hole wall 112, a third hole wall 113 and a fourth hole wall 114 which are sequentially connected end to end, wherein the first hole wall 111 and the second hole wall 112 are arranged oppositely, and the third hole wall 113 and the fourth hole wall 114 are arranged oppositely. The first limiting portion 20 and the second limiting portion 30 have a first position and a second position, the first limiting portion 20 is flexibly connected to the first hole wall 111, and the second limiting portion 30 is flexibly connected to the second hole wall 112. The first limiting portion 20 and the second limiting portion 30 are respectively connected to the edges of the first hole wall 111 and the second hole wall 112, so that the first limiting portion 20 can be bent around the connecting edge of the first limiting portion 20 and the first hole wall 111 relative to the substrate 10, and the second limiting portion 30 can be bent around the connecting edge of the second limiting portion 30 and the second hole wall 112 relative to the substrate 10.

Of course, as shown in fig. 4, the first limiting portion 20 and the second limiting portion 30 may be bent to the second position, that is, the first limiting portion 20 and the second limiting portion 30 both form an included angle larger than 90 ° with the substrate 10, and then the electric bottom box is inserted into the through hole 11, so that the electric bottom box can deform the first limiting portion 20 and the second limiting portion 30 in a direction away from each other, and then the first limiting portion 20 and the second limiting portion 30 can clamp the electric bottom box under the action of their own elastic forces, so that the first limiting portion 20 and the second limiting portion 30 cooperate to clamp the electric bottom box.

Alternatively, the included angle between the third inclined surface 32 and the substrate 10 is equal to the included angle between the fourth inclined surface 33 and the substrate 10, and it can be understood that the second limiting portion 30 has an isosceles trapezoid structure.
