[0026] The following further describes the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present embodiments do not limit the present utility model. Any similar structures and their similar changes adopted in the present utility model shall fall within the protection scope of the present utility model.

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, a mortise and tenon structure of a lapping building block includes a first building block body 1, a second building block body 2 and a third building block body 3. The first building block body 1, the second building block body 2 and the third building block body 3 are all cubic building blocks. The widths of the first building block body 1, the second building block body 2 and the third building block body 3 are the same. The heights of the first building block body 1, the second building block body 2 and the third building block body 3 are the same. The lengths of the first building block body 1 and the second building block body 2 are the same or different. As Figure 1 shown, as Figure 1The small black dot at the lower left corner shown is the origin. The horizontal transverse direction is the X-axis, the horizontal longitudinal direction is the Y-axis, and the vertical direction is the Z-axis. Specifically, the first building block body 1 and the second building block body 2 are long in the X-axis direction, wide in the Y-axis direction, and high in the Z-axis direction. At least one set of first card slots 11 is provided on the first building block body 1, and at least one set of second card slots 21 is provided on the second building block body 2. The first building block body 1 and the second building block body 2 are lapped through the mutually cooperating first card slots 11 and second card slots 21. A through second card slot 31 is opened on the side wall of the third building block body 3 in the Z-axis direction, and the third building block body 3 is lapped on the first building block body 1 or the second building block body 2 through the second card slot 31.

[0028] Regarding the structure of the card slots, specifically as follows: The first card slot 11 is a through slot opened on its side wall along the Y-axis and Z-axis respectively on the first building block body 1 symmetrically about the center axis in the X-axis direction. The slot 111 along the Y-axis and the slot 112 along the Z-axis are connected. The lengths of the slot 111 and the slot 112 are the same and less than the width of the first building block body 1. The second card slot 21 is a through slot opened on its side wall along the Y-axis and Z-axis respectively on the second building block body 2 symmetrically about the center axis in the X-axis direction. The slot 211 along the Y-axis and the slot 212 along the Z-axis are connected. The length of the slot 211 is the same as the length of the first slot, and the length of the slot 212 is adapted to the width of the first building block body 1. The length of the second card slot 31 is adapted to the width of the first building block body 1. Multiple groups of the third building block body 3 with the same or different lengths are provided, and at least one group of the second card slots 31 is provided.

[0029] Regarding the splicing of the lapped building blocks, as Figure 6 、 Figure 7 、 Figure 9 and Figure 10 shown, multiple groups of the first building block body 1, the second building block body 2, and the third building block body 3 are respectively provided. The first building block body 1 and the second building block body 2 are alternately lapped in sequence, and the third building block body 3 is assembled on the first building block body 1 or the second building block body 2 to form a modeling structure.

[0030] Since a stepped card slot is provided between the first card slot and the second card slot, when the two are clamped, multiple surfaces are in contact respectively. There are multiple guiding surfaces when the first card slot and the second card slot are clamped, making it more convenient for the building block bodies to lap; at the same time, multiple contact surfaces restrain each other, making the building block bodies more stable when lapping, and the formed model after lapping is more firm and not easily toppled by external forces.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
