Assembly structure of building block

Abstract

The present application provides an assembly structure of a building block, and particularly relates to an assembly structure allowed to be engaged with secondary main bodies of additional building blocks from various directions and generating the encasing and decorating effects. The assembly structure includes a main body of a building block. An exterior of the main body is provided with connection surfaces. The connection surfaces face toward various directions of the circumferences of the main body, respectively. Each of the connection surfaces includes at least one stud to be engaged with an engaging recess of a secondary main body of an additional building block. Therefore, the main body can be engaged with the secondary main bodies of the additional building blocks from various directions to enhance the overall aesthetic appearance and make assembling building blocks more convenient.

What is claimed is: 
     
         1 . An assembly structure of a building block, comprising:
 a main body, an exterior of the main body including a plurality of connection surfaces, the connection surfaces facing toward various directions of the circumferences of the main body, respectively,   wherein each of the connection surfaces includes at least one stud to be engaged with a secondary main body of an additional building block, and the secondary main body is provided with an engaging recess corresponding to the stud.   
     
     
         2 . The assembly structure of the building block according to  claim 1 , wherein the secondary main body includes a decoration surface encasing the secondary main body at a side corresponding to be away from the main body. 
     
     
         3 . The assembly structure of the building block according to  claim 1 , wherein the secondary main body includes at least one stud at a side corresponding to be away from the main body. 
     
     
         4 . The assembly structure of the building block according to any one of  claims 1  to  3 , wherein the main body includes a polyhedron. 
     
     
         5 . The assembly structure of the building block according to  claim 4 , wherein the polyhedron includes a hexahedron. 
     
     
         6 . The assembly structure of the building block according to any one of  claims 1  to  3 , wherein the main body includes a recess, the recess is defined in at least one connection surface, and the studs of the main body is formed by extending from a bottom wall of the recess. 
     
     
         7 . The assembly structure of the building block according to  claim 4 , wherein the main body includes a recess, the recess is defined in at least one connection surface, and the studs of the main body is formed by extending from a bottom wall of the recess. 
     
     
         8 . The assembly structure of the building block according to  claim 5 , wherein the main body includes a recess, the recess is defined in at least one connection surface, and the studs of the main body is formed by extending from a bottom wall of the recess.
