For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0015] Please refer to Figure 1-2As shown in the figure, the present utility model provides a stackable and assembled protective circuit board structure, which includes at least two circuit board bodies 10, and also includes a bottom mounting structure, multiple sets of stacking structures corresponding to the number of circuit board bodies 10, and two inverted U-shaped protective rods 20; the bottom mounting structure includes two mounting plates 14, two first C-shaped mounting seats 11, and two second C-shaped mounting seats 13. The first C-shaped mounting seats 11 and the second C-shaped mounting seats 13 on the same side are respectively arranged on the opposite sides of the same side mounting plate 14 in the length direction and are rotatably connected to one side of the mounting plate 14 through a rotating shaft; the four sides of the circuit board body 10 are respectively fitted and arranged between the two first C-shaped mounting seats 11 and the two second C-shaped mounting seats 13; a number of waist-shaped holes 12 are linearly and orderly arranged on both mounting plates 14 along their length directions. When in the installation and fixation state, the mounting plates 14 are fixed by screws passing through the waist-shaped holes 12; first positioning insertion holes 23 are opened at the tops of the two first C-shaped mounting seats 11 and the two second C-shaped mounting seats 13; each set of stacking structures includes four third C-shaped mounting seats 17, positioning pins 16 are arranged at the bottoms of the four third C-shaped mounting seats 17, and second positioning insertion holes 18 are opened at the tops of the four third C-shaped mounting seats 17. Anti-slip soft pads are attached to the inner cavities of the first C-shaped mounting seats 11, the second C-shaped mounting seats 13, and the third C-shaped mounting seats 17, and are in contact with the circuit board by abutting against the anti-slip soft pads.

[0016] When in the assembly state, the four third C-shaped mounting seats 17 are respectively fitted and connected to the four sides of the circuit board body 10; the four third C-shaped mounting seats 17 above the bottom mounting structure are all fixedly connected by inserting the positioning pins 16 into the first positioning insertion holes 23; except for the first circuit board body 10 above the bottom mounting structure, the other circuit board bodies 10 are all fixedly connected by inserting the positioning pins 16 into the second positioning insertion holes 18 of the third C-shaped mounting seats 17 below them; the two inverted U-shaped protective rods 20 are respectively inserted across the second positioning insertion holes 18 of the two third C-shaped mounting seats 17 on the same side at the top.
