Description

Building block combination

The invention relates to a puzzle building block combination, in particular to a building block combination that can use connecting rods to connect combination pieces and assemble them into various shapes.

Building block combination is an educational toy that is both educational and entertaining. Users can use their imagination and creativity to combine building blocks of various shapes into various shapes. During the play process, children's creativity and creativity are trained. space concept.

There is an existing building block combination, which mainly includes a plurality of combination pieces and connecting rods used to connect the plurality of combination pieces. Each combination piece is mainly polygonal, and each side of each combination piece is provided with a buckle. During assembly, the connecting rods are It snaps into the buckling portion of the two assembly pieces to connect the two assembly pieces. The assembly piece can usually pivot relative to the connecting rod to change the assembly angle between the two assembly pieces, and multiple connecting rods can be used to connect multiple assembly pieces. Assemble into various three-dimensional shapes.

However, although the existing building block combinations allow the assembly piece to pivot relative to the connecting rod, the angle at which the two assembly pieces can pivot is limited. When the angle between the two assembly pieces is too small, it is easy to cause the assembly piece to fall off the connecting rod. Therefore, it is difficult for existing building block combinations to allow two adjacent building block pieces to overlap each other, which limits the flexibility of assembly.

In addition, the connecting rods can usually only be fastened to the buckling portions on the sides of the combined pieces, which makes the connection methods between the combined pieces relatively limited.

In view of the above shortcomings, the main purpose of the present invention is to provide a building block combination whose connecting rod can flexibly connect two building blocks.

In order to achieve the above purpose, the building block combination provided by this new model includes: A connecting rod, which is used to connect two combined pieces. The connecting rod includes a middle rod and two side rods. The two side rods are combined with the periphery of the middle rod and arranged at angular intervals. The length of each side rod is less than the length of the side rod. The length of the central pole, the opposite ends of which extend beyond the opposite ends of the two side poles; and Each of the combination pieces includes an engaging portion, which is formed on one side of the combination piece, and includes a fitting groove. Each combination piece can be locked with the fitting groove of the engaging portion. on one side of the connecting rod.

Another building block combination provided by this new model includes: A connecting rod, which is used to connect two combined pieces. The connecting rod includes a middle rod and two side rods. The two side rods are combined with the periphery of the middle rod and arranged at angular intervals. The length of each side rod is less than the length of the side rod. The length of the central pole, the opposite ends of which extend beyond the opposite ends of the two side poles; and Each of the combination pieces includes a connection hole, and each connection hole penetrates the combination piece. The opposite ends of the middle rod of the connecting rod respectively extend into the connection holes of the two combination pieces.

Utilizing the above technical features, the connecting rod of the new building block combination can be buckled into the fitting grooves of the engaging parts of the two assembly pieces with the two side rods located on the periphery of the middle pole, so that the two assembly pieces can be connected in the middle pole. The periphery pivots to increase the pivot angle of each assembly piece, thereby allowing the two assembly pieces to overlap each other; the opposite ends of the middle rod can also be used to extend into the connecting holes of the two assembly pieces to connect the two assembly pieces. The assembly methods of building block combinations are more diverse.
