Building block

Abstract

The application discloses a building block. comprising three shapes of cuboid hollowed-out building blocks, connectors and hinges, built by means of connectors and hinges. The application of a building block combination has a simple structure, a fast assembling speed, a diverse gameplay, and may effectively improve the amusement and interest in use.

What is claimed is: 
     
         1 . A building block, comprising cuboid hollowed-out building blocks, connectors and hinges, the hinges being connected via a rotating shaft on male and female parts for free rotation at different angles, the cuboid hollowed-out building blocks being stacked and built mutually, or being freely built and combined via hollowed-out holes on the building blocks with the connectors and the hinges. 
     
     
         2 . The building block according to  claim 1 , wherein the length, width and height of the cuboid hollowed-out building blocks are logically matched in size, 3H=D and 5D=L, the hollowed-out holes thereon are logically matched in size with the connectors and the connecting columns on the hinges. 
     
     
         3 . The building block according to  claim 1 , wherein upper and lower connecting columns on the connectors and hollowed-out holes on the cuboid hollowed-out building blocks are logically matched in size. 
     
     
         4 . The building block according to  claim 1 , wherein rotating shaft columns on the male and female parts of the hinges and rotating shaft holes are logically matched in size for free rotation at different angles after assembly, and the connecting columns thereon are logically matched in size with the hollowed-out holes on the cuboid hollowed-out building blocks.
