[0058] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present application.

[0059] The present application provides a modular mortise and tenon assembly building block, which comprises a basic component and a rotating lock component b, the shape of the basic component and the rotating lock component b is formed by setting a splicing slot c on the rectangular side surface of a cuboid base body, the base body end surface e of each cuboid base body forming the basic component and the rotating lock component b is square and has the same size, and the slotting depth of the splicing slot c set on the basic component and the rotating lock component b is half of the square side length of the base body end surface e.

[0060] All the sizes of the basic component and the rotating lock component b and the splicing slot c set on the above-mentioned components have a unified proportion unit, that is, the slotting depth of the splicing slot c is one basic proportion unit, and the square side length of the base body end surface e is two proportion units.

[0061] The types of the basic component are seven, and the seven basic components are respectively: a first basic component a1, a second basic component a2, a third basic component a3, a fourth basic component a4, a fifth basic component a5, a sixth basic component a6 and a seventh basic component a7, wherein the base body length of the first basic component a1, the second basic component a2, the third basic component a3, the fourth basic component a4, the fifth basic component a5 and the sixth basic component a6 is six proportion units, and the base body length of the seventh basic component a7 is eight proportion units.

[0062] The rectangular side surface length of the cuboid base body of the rotating lock component b is six proportion units.

[0063] The splicing slots c set on the basic component and the rotating lock component b are divided into a type slot c1, a two-type slot c2, a three-type slot c3, a four-type slot c4 and a five-type slot c5 according to the different groove widths; the length direction of the one-type slot c1 along the basic component is one proportion unit, the length direction of the two-type slot c2 along the basic component is two proportion units, the length direction of the three-type slot c3 along the basic component is three proportion units, the length direction of the four-type slot c4 along the basic component is four proportion units, and the length direction of the five-type slot c5 along the basic component is six proportion units. Figures 1-9 Therefore, any two or more components can realize assembly matching. At the same time, the position locking of the assembly combination is realized by the position of the rotating lock component b or the sliding basic component in the assembly case, so that the assembled combination case becomes a whole, as shown in FIG. 11, FIG. 15 and FIG. 16.

[0064] The cooperation of the spin-locking component b and the base component is described as follows:

[0065] During the assembling process, when the spin-locking component b is assembled with the selected fourth base component a4 and the fifth base component a5, the spin-locking component b can be rotated in position through the rotating shaft b1, as shown in FIG. 10. The position rotation of the spin-locking component b can achieve the position locking of the assembled combination in the complete assembling case, as shown in FIG. 11. The spin-locking component b plays a locking role in the assembled combination, and can fix the assembled combination as a whole. In the case where locking is not required, the spin-locking component b can be used as a base component for assembling.

[0066] Regarding the foot d, as shown in FIG. 3, FIG. 4, FIG. 5, and FIG. 6, the foot d is a cube with a side length of one proportional unit, and the foot d is used to enrich the assembling effect, as shown in FIG. 13, and can realize the imagination of the shaped leg foot, making the shape more vivid, as shown in FIG. 14.

[0067] In order to further increase the vividness of the assembled combination effect, an eye pattern can be arranged on the base end surface e of the spin-locking component b, as shown in FIG. 14.

[0068] The present application provides some assembling cases to further illustrate the cooperation mode of the modular components and the provided mortise and tenon assembling logic.

[0069] Case one (as shown in FIG. 11)

During the assembling process, the spin-locking component b is pre-assembled, and after all the components are assembled, the positions of all the selected components are locked as a whole through the position rotation of the spin-locking component b, and the positions of the spin-locking component b are rotated again to reset to unlock the disassembly of the combination. Referring to FIG. 11, the complete effect of the assembling locking of case one and the exploded view of the components of the case are shown.

[0071] In order to better illustrate the content of the present application and the modular mortise and tenon assembling logic, case one (as shown in FIG. 11) is further assembled and demonstrated with reference to FIG. 12. Case one can be further assembled to form a more complex combination effect (as shown in FIG. 12). More assembling combination effects can be obtained by stacking case one (as shown in FIG. 11), and the locking effect of the assembling combination can still be achieved (as shown in FIG. 13).

[0072] Case two (as shown in Fig. -14)

[0073] Referring to Fig. -14, according to the expansion of the assembly logic of case one (as shown in Fig. -11), more components are selected for assembly combination, which can achieve more diverse assembly effects, and more vivid visual effects and modeling associations can be achieved by drawing eyes or other types of patterns on the base end surface (e) of some components.

[0074] The above-mentioned case one and case two show one type of the many assembly combinations of the present application. Based on the basic components and rotating lock components provided by the present application, a variety of assembly and locking combinations can be achieved. See case three and case four.

[0075] Case three (as shown in Fig. -15)

[0076] The case three provided by the present application selects three first basic components a1 and three sixth basic components a6 for assembly combination. Through the assembly and cooperation of each part, a Chinese traditional Luban lock shape is formed, but the internal structure is different from the assembly structure of the traditional Luban lock. Case three (as shown in Fig. -15) further demonstrates the diverse assembly methods and expansion space of the modular mortise and tenon assembly blocks.

[0077] Case four (as shown in Fig. -16)

[0078] The case four provided by the present application selects one first basic component a1, eight sixth basic components a6, and two seventh basic components a7 for assembly combination. Through the assembly and cooperation of each part, 11 components are combined and locked into a whole. The present application is a modular mortise and tenon assembly block, and there are eight types of components including basic components and rotating lock components. This design is to achieve more diverse assembly combination effects, but selecting a certain number of three types of all components can achieve effective assembly and locking combination.
