摘要
The present invention is not an assembly-type toy where a user completes an assembly-type finished product based on a manual. The invention relates to a unit block in which the insertion portion is provided with a special structure and shape. The present invention provides a unit block in which a coupling portion and an insertion portion are provided integrally, and when the desired object is to be implemented, as a means for using the unit block, the insertion portion is sized to be fitted inside the coupling portion. At the upper end of the coupling part, only the outer wall of the coupling part becomes narrow and the unit block and the four side surfaces of the uniting part are integrated with circular through coupling holes. A tube expansion part is formed, and a unit block having a structure having a `` ┫ ''-shaped internal expansion groove is formed in the center of the surface of the coupling part. When coupled vertically with other unit blocks, When the “┫” -shaped support piece is fitted and connected to the formed “┫” -shaped internal expansion concave groove and horizontally connected to other unit blocks, it is formed in the through-coupling hole of the connecting portion. A partial protrusion formed on the surface of the support shaft is fitted in the partially expanded tube. It is to provide a coupling means of the applied unit block so as to ensure high bonding strength.
