Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

Some embodiments of the present invention provide a modular reconfigurable fingertip block, as shown in fig. 1, which includes 2 cubes 10 and a connecting member 20 for connecting the cubes 10 and forming a fingertip block; when n is 8, the formed fingertip block is shown in fig. 2. In some preferred embodiments, as shown in fig. 3 and 4, each top corner of the cube 10 is provided with a three-sided slot 11, three sides of each slot 11 are provided with through holes 12 communicated with the slots 11, and as shown in fig. 5, the side walls of the through holes 12 are provided with annular grooves 13; in some preferred embodiments, as shown in fig. 6, the connecting member 20 includes a connecting block 21 and two connecting posts 22 connected to the connecting block 21, the connecting posts 22 are connected to the through holes 12 in a matching manner, and the side walls of the ends of the connecting posts 22 are provided with annular protrusions 23 connected to the annular groove 13 in a matching manner. The material of the fingertip blocks is preferably an elastic material. In some preferred embodiments, the connecting block, the connecting post and the annular projection are integrally formed.

In some preferred embodiments, each side of each cube 10 is a circular arc transition structure.

The utility model provides a modularization restructural fingertip building blocks, it comprises two kinds of parts of cube and connecting piece, can splice according to user self idea, changes according to part quantity difference and connection scheme, can splice fast and make up into multiple form, and the different shapes of concatenation are seen in figure 7 and figure 8. The modular reconfigurable fingertip building block can be spliced into a shape with an infinite rotation function. The splicing process of infinite turn is shown in fig. 9.

In some preferred embodiments, as shown in fig. 10, in order to improve the stability of the assembled fingertip block, the width of each connecting piece 21 is equal to the diameter of the connecting post 22, as shown in fig. 11, and it needs to be small enough to ensure that the connecting pieces 20 are not blocked by the two other slots 11 after being matched and connected with the slots 11, and thus the connection between the connecting pieces and the slots 11 is not affected. As shown in fig. 12, in some preferred embodiments, the fingertip brick further includes a reinforcing member 30, the reinforcing member 30 includes a reinforcing block 31 and two reinforcing columns 32, and the sum of the height of the reinforcing block 31 and the height of the connecting block 21 is equal to the height of the slot 11; the side wall of the end of the reinforcing column 32 is provided with a second annular protrusion 33, as shown in fig. 13, the top surface of each connecting block 21 is provided with two reinforcing grooves 24 which are matched with the reinforcing column 32, as shown in fig. 14, and the reinforcing grooves 24 extend into the connecting column 22; the side wall of the reinforcing groove 24 is provided with an annular groove 25 which is matched with the second annular bulge 33.
