The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Fig. 1 to 5 show schematic views of several basic building elements of the utility model. According to the different number of the basic building units, the basic building units are divided into a unit, a two unit, a three unit, a four unit and a five unit. In the following, a unit will be taken as an example, and the construction of the foundation construction unit of the present utility model will be described with emphasis.

With particular reference to figures 1 and 2, a unit building element comprises a male coupling 1 and a female coupling 2 arranged one above the other. The male coupling 1 is located in the upper region and the female coupling 2 is located in the lower region. Releasable interconnection between two adjacent one-unit building elements can be achieved by mating the male coupling 1 on one of the one-unit building elements with the female coupling 2 on the other one-unit building element, or mating the female coupling 2 on one of the one-unit building elements with the male coupling 1 on the other one-unit building element. In this embodiment, the upper male coupling 1 and the lower female coupling 2 are distributed up and down along the central axis Z, enabling the building connection of a unit building element adjacent in the Z-axis direction.

The male coupling 1 is generally cylindrical in shape, having a height h, and has a first side wall 12. The female coupling 2 is generally cylindrical in shape, with a height H, and has a second side wall 22. The bottom surface is recessed upwards forming a second cavity 21, the second cavity 21 being adapted to receive the insertion of the male coupling 1 of another building unit. The second recess 21 is sized to fit the outer surface of the first side wall 12 of the male coupling 1. The height H of the male coupling 1 is smaller than the height H of the female coupling 2. The diameter of the male coupling 1 is smaller than that of the female coupling 2, and a step 14 is formed between the coupling portions of the two. The step 14 forms a mating mounting surface with an adjacent other foundation building unit.

In order to improve the smoothness of the sliding fit between the male coupling 1 and the female coupling 2 of an adjacent one-unit building element, guide strips 25 are provided on the inner wall of the second recess 21. Preferably, the guide strips 25 are distributed in a central symmetry, 4 in total, and the outer surface of the first side wall 12 of the male coupling 1 can slide along the guide strips 25 inside the second cavity 21.

When two adjacent building elements are mounted by mating the male coupling 1 on one of the building elements with the female coupling 2 on the other building element, the two building elements can be turned in relation to each other. In order to increase the smoothness of the sliding, it is preferred that the top surface of the male coupling 1 is recessed downwards to form a first recess 11, and that the top edge of the first recess 11 is provided as a first chamfer 13, making the running fit smoother by reducing the friction area of the top surface of the male coupling 1 as a mating with the second recess 21 of the female coupling 2 of the other building unit. Meanwhile, the first cavity 11 may also serve as a receiving cavity for mounting contact terminals of electrical components and the like.

Preferably, a second chamfer 23 is formed at the bottom edge of the second cavity 21 of the female coupling 2 and a third chamfer 24 is formed at the step 14 of the female coupling 2. The provision of the second and third chamfer edges 23, 24 allows for the adjacent two building elements to form a natural nail clasp into a narrow slit 31 at the joint when assembled, facilitating release and detachment of the two, as shown in figure 30. In other embodiments, the male coupling 1 and the female coupling 2 are detachably connected at the connecting portion step portion 14, which is convenient for processing and installing circuit components. In other embodiments, the male coupling 1 and the female coupling 2 are integrally formed in a unit construction element.

With continued reference to figures 3 to 5, the two unit building elements comprise two side-by-side connected one unit building elements and a connection 3 adapted to connect the two. Preferably, the two units are formed by integrally formed connection of two one-unit building elements. The connecting portion 3 is a connecting bar parallel to the guide bar 25. The stepped portions 14 of the two-unit are flush. In other embodiments, other forms of engagement, such as snap-fit, plug-in, etc., of the connection portion are also fully feasible.

The three-unit, four-unit building element is similar to the two-unit. Are each formed by three side-by-side connected one-unit building elements and a connection 3 between two adjacent one-unit building elements. The connecting portion 3 is a connecting bar parallel to the guide bar 25. The stepped portions 14 of the plurality of one units are flush with each other. The three-unit building element and the four-unit building element are integrated into a "one".

As shown in figure 5, the three-unit building element also comprises three one-unit building elements interconnected in a right-angled configuration, being integrated in a "master" shape. The connecting portion 3 is a connecting bar parallel to the guide bar 25. The stepped portions 14 of the plurality of one units are flush with each other.

The one-unit, two-unit, three-unit and four-unit building elements described above allow for spatial extension of the foundation building element in the Z-axis direction. But building for extensions such as arc angles, turns, directions towards the X-axis or Y-axis, etc. is not very attractive.
