The following detailed description based on the embodiments and the drawings is as follows:

1, it discloses a building block device, which includes a storage box 50 and a building block group 60. The storage box 50 is composed of a base 70 and a top cover 80 covering the base 70. The building block group 60 is composed of The base 70 is composed of a plurality of building blocks. The base 70 has a storage slot 72 for the building block group 60 to be placed. The top cover 80 can cover the base 70 to hide the building block group 60 inside; the slot of the storage slot 72 There are 35 positioning grids 71 on the bottom, which can be used to form a single-layer plane pattern after the above-mentioned building block group 60 is arranged. 15 positioning grooves 81 are provided on the surface of the top cover 80 to allow the above-mentioned building block group 60 to be placed in and stacked out. The three-sided pyramid shape of the layer, each building block of the building block group 60 is composed of 1 to 5 units, and the units are connected at a two-dimensional angle of horizontal X or vertical Y. The total number of units of the building block group 60 is 35 .

When the building block unit of the building block group 60 is a three-dimensional square, the shape of the positioning grid 71 is a square, which has a square groove bottom; the shape of the positioning groove 81 is a hexagon, which consists of a triangular groove bottom 811 and It is composed of three inclined surfaces 812 surrounding the bottom 811 of the groove. If the building block unit of the building block group 60 is spherical, the positioning grid 71 must be in the shape of a semicircular socket, and the positioning groove 81 must also be in the shape of a semicircular socket. Among them, the aesthetics, smoothness, and regularity of a square shape will be better than that of a spherical shape.

Please refer to Figures 1, 2 and 3, the above-mentioned middle base 70 is in the shape of a triangle, and the positioning grid 71 is arranged in ten rows from top to bottom, including one in the first row and two in the second row. 3 in the third row, 2 in the fourth row, 3 in the fifth row, 4 in the sixth row, 5 in the seventh row, 4 in the eighth row, 5 in the ninth row, and 6 in the tenth row. The lower positioning grids 71 are adjacent to each other by the grid side and the grid side at a 45 degree angle, and the left and right positioning grids 71 are adjacent to each other by the grid corner and the grid corner at a horizontal angle; each building block of the building block group 60 is based on Position the grid 71 and place them separately, and finally can be assembled into a single-layer plane pattern shape.

Please refer to Figures 1, 4, and 5, the above-mentioned middle top cover 80 is in the shape of a triangle, each side is provided with 5 positioning grooves 81, and the positioning grooves 81 are arranged in five rows from top to bottom, of which there is one in the first row. , 2 in the second row, 3 in the third row, 4 in the fourth row, and 5 in the fifth row. The upper and lower positioning grooves 81 are adjacent to each other by the groove side and the groove side at an angle of 60 degrees, left and right The positioning grooves 81 are adjacent to each other by the groove side and the groove side at a horizontal angle; each building block of the building block group 60 is placed according to the position of the positioning groove 81, and finally can be stacked like a pyramid with 5 layers of three-sided cones modeling.

Please refer to Figures 1 and 6, the base 70 is a triangular shape, which is divided into upper and lower layers 73 and 74. The outer diameter of the lower layer 74 is larger than that of the upper layer 73. The lower layer 74 of the first and second sides is connected with a long convex edge 75, and the lower layer 74 of the third side forms a short opening 76, and the length of the two long convex sides 75 is greater than the short opening 76; furthermore, the top The shape of the cover 80 is the same as that of the base 70, two side edges are provided with long notches 82, and the other side edge is provided with a short opening 83. The length of the two long notches 82 is greater than the short opening 83; when the top cover 80 The bottom surface is concave and can cover the upper layer 73 of the base 70, and the bottom edge can rest on the top edge of the lower layer 74 of the base 70. The two long notches 82 of the top cover 80 can be aligned with the two long convex sides 75 of the base 70. The anastomosis does not produce a gap, and the short opening 83 and the short opening 76 of the base 70 are symmetrical up and down to form an opening gap; this design, like a fool-proof structure, allows the user to intuitively complete the operation accurately and without error. Avoid placing the top cover 80 on the base 70 by mistake.

In the above, in order to reduce the overall weight, the base 70 and the top cover 80 are replaced by hollow plastic shells instead of solid disks, especially the top cover 80, whose bottom surface is concave, when the top cover 80 covers the base 70 After being mounted, the upper layer 73 of the base 70 can be covered, and the bottom edge of the outer periphery is tightly closed with the top edge of the lower layer 74 of the base 70, so that a stable covering effect can be achieved; It is hollow, and the units pass through each other. Therefore, compared with the old-style building blocks, it is necessary to reduce a lot of weight, reduce the use of plastic materials, and reduce the manufacturing cost.

Units 1 and 2 are connected horizontally, Units 3 and 4 are connected horizontally, Units 1 and 4 are connected vertically, Units 3 and 5 are connected vertically; The seventh is the building block (57). Units 1, 2, and 3 are connected horizontally, Units 4 and 5 are connected horizontally, and Units 1 and 5 are connected vertically; The eighth building block (58), the first, second, and third units are connected horizontally, and the second, fourth, and fifth units are connected vertically; The ninth building block (59). Units 1, 2, and 3 are connected vertically, units 4 and 5 are connected vertically, units 1, 4 are connected horizontally, and units 2 and 5 are connected horizontally. As described in claim 1, 35 units are used as a modular building block device, wherein the base (70) is divided into upper and lower layers (73) and (74), and the outer diameter of the lower layer (74) is larger than that of the upper layer. (73) is large, so the outer periphery is stepped, and the lower layer (74) of the first and second sides is connected with a long convex edge (75), and the lower layer (74) of the third side forms a short opening (76). ), the length of the two long protruding sides (75) is greater than the short opening (76); further, the top cover (80) has the same shape as the base (70), and the bottom edges of the two sides are provided with long notches ( 82), the bottom edge of the other side is provided with a short opening (83), the two long openings The length of the opening (82) is greater than the short opening (83); the bottom surface of the top cover (80) is concave, which can cover the upper layer (73) of the base (70), and the bottom edge can rest on the lower layer (70) of the base (70). 74) On the top edge, the two long notches (82) of the top cover (80) can be matched with the two long protruding edges (75) of the base (70) without a gap, and the short opening (83) is consistent with the The short opening (76) of the base (70) is symmetrical up and down to form an opening gap.
