detailed description

The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and thus are only examples, and are not intended to limit the scope of the present invention.

As shown in FIG. 1 and FIG. 2, the magnetic building block provided by the first embodiment of the present invention comprises a cube-shaped building block body 1. The building block body 1 can be made of wood or a low-density plastic material.

A blind hole 101 is disposed in a center of each face of the block body 1. A cylindrical magnet 2 is disposed in each of the mounting blind holes 101, and three faces adjacent to each other in the block body The outer side of the magnet on the front (front, top, and left sides) is the same as the S pole, and the outer sides of the magnets on the other three faces (back, bottom, and right) are also N poles.

The hole diameter of the mounting blind hole is slightly smaller than that of the cylindrical magnet, and the interference of the magnet 2 is installed in each of the mounting blind holes 101, so that the magnet can be prevented from coming out of the mounting blind hole. The opening of the blind hole is inclined at an angle of 45°, and the width and height of the oblique angle 102 are 20 wires (2 mm). The function of the chamfer is to facilitate pressing the magnet 2 into the blind hole of the installation to improve assembly. Efficiency, and reduce damage to the building block body, reducing the scrap rate of the building blocks. Moreover, the outer end surface of each magnet on the building block body is lower than the surface of the building block body by 0.2 mm, so that the outer end faces of the magnets are slightly concave on the surface of the building block, which can effectively prevent the magnetic building blocks from being adsorbed and connected to each other. The magnets wear out due to frequent contact with each other. A sticker 3 is attached to each surface of the building block body to beautify the appearance of the building block.

As shown in FIG. 3, a building block assembly according to a second embodiment of the present invention includes a base connecting block 4 and a plurality of the above-mentioned magnetic building blocks.

A plurality of magnets 2 are disposed on the top surface of the base connecting block 4, and the magnets are embedded on the top surface of the base connecting block. The magnetic building block is affixed to the magnet on the top surface of the base connecting block by a magnet on its surface. Referring to FIG. 4, the bottom surface of the base connecting block has a plug hole 401, and the base connecting block can be assembled to the plug post of the Lego building block through the insertion hole 401 of the bottom surface thereof, thereby The combination of LEGO building blocks enriches the way the blocks are played.

As shown in FIG. 5, a building block assembly according to a third embodiment of the present invention is different from the second embodiment in that the bottom surface of the base connecting block has a plug boss 402, see FIG. The dashed line is an illustration of a LEGO building block that can be assembled to the insertion holes of the LEGO bricks by the plug posts 402 on its bottom surface.
