Modular building block device

The present invention relates to a building block, in particular to a modular building block device.

There are many kinds of building block products sold in the retail market today, which can be said to be varied in function and shape, and by combining and dismantling building blocks of various shapes, they can be converted into another unique shape. In addition to the replayability of the game, it also allows players to stimulate and cultivate their imagination and creativity in the process of assembling building blocks. Only when the player wants to create a large-area and large-scale three-dimensional changeable and polymorphic configuration (such as bunkers, walls, churches, rockets, tanks, ships, etc.) building blocks, they will be affected by the size and shape of the building blocks themselves. Restriction, and the need for a larger number of building blocks will lead to more investment in the production of building block raw materials, which requires more investment in both money and assembly time, because more time and money are spent in the assembly process, which is easy to reduce the number of players. interest, and there will be restrictions on the age of the players.

In addition, there is another splicing combination product commonly known as Qiaopin on the market, which is mainly for preschool children to make some simpler shape combinations. , and the strength of the combination is insufficient, and disintegration or collapse is likely to occur. Therefore, there is still the disadvantage that the three-dimensional building block combination cannot be easily assembled.

In the type of the correspondingly used, the fixing holes 121 of the extending plates 12 are point-symmetrically distributed at a reference point Z. It is worth noting that the fixing holes 121 of the extension plate 12 having a triangular shape are point-symmetrically distributed, so that when each main body unit 1 having a triangular shape is connected to other main body units 1, each of the main body units 1 The force on one side is the same, and the problem of deformation is not easy to occur.

Referring to FIG. 11 , the user can use the main body units 1 in different forms, so that the user can have more connection methods to flexibly use the finished product form after assembly. For example, as shown in FIG. 11 , several square main units 1 and several triangular main units 1 are used at the same time, so that users can assemble them into a house-like shape. It can be seen that the whole of the second embodiment can be seen through the triangular main unit. 1. It is indeed more flexible to assemble and extend the elasticity.

Referring to FIGS. 12 and 13 , it is a third embodiment of the modular building block device of the present invention. The difference from the first embodiment is that the main unit 1 includes a plurality of substrates 11 arranged at equal intervals. In the third embodiment, each substrate 11 may be any one of a circle, a square, a triangle, a polygon, or an X-shape. As shown in FIG. 12 , each of the substrates 11 is circular, and the number of the substrates 11 is five as an example, and it can also be four, which is not limited thereto. It should be noted that reducing the area size of each substrate 11 can effectively improve the utilization rate of manufacturing materials and reduce the overall weight of each main unit 1 .
