[0002] Building block toys are one of the types of toys frequently played with by children, and various combinations can be formed through different assembling ways; the building block toys are interesting, and can attract children, inspire mental activities of children, and promote development of the intelligence and operational ability of children.

[0003] Traditional building block toys are connected mainly through grooves and lugs matched with the grooves. The building block toys can be connected forcibly even in an incorrect mounting way, and consequentially the inspiration effect on children is poor; in addition, the building blocks are completely fixed after being assembled, so that on the one hand, the combination diversity of the building blocks is limited, and on the other hand, certain motions of a combined assembly cannot be achieved by children, and the mobility of the assembly is extremely poor.

[0004] Magnetic building blocks are provided for solving the problems, however, magnetic bodies are directly pushed into the existing magnetic building blocks or only fixed in the building blocks with glue, and exposed out of the surfaces of the building blocks, magnets are prone to falling, and once the magnets fall, serious dangers can be caused if the magnets are ingested by children; the building blocks of the structure cannot be connected firmly and are poor in inspiration effect.

[0005] The above defects are worth overcoming.

[0009] Furthermore, the magnetic body fixing sleeve is of a hollow cylindrical structure.

[0010] Furthermore, the section of the insertion groove is of a C-shaped structure, the side face of the clamping groove is sealed, the lower side of the clamping groove is open, and the section of the clamping groove is of an inverted-U-shaped structure.

[0011] Furthermore, the first magnetic body is transversely inserted into the insertion groove, the second magnetic body is longitudinally clamped into the clamping groove from bottom to top, and sealing between the first magnetic body and the magnetic body fixing sleeve as well as between the second magnetic body and the magnetic body fixing sleeve is achieved through ultrasonic waves.

[0012] Furthermore, the upper side of the first magnetic body is the N pole, and the lower side of the second magnetic body is the S pole.

[0013] Furthermore, the magnetic bodies are magnets.

[0014] Furthermore, the magnetic bodies are permanent magnets.

[0015] According to the above structure, the invention has the beneficial effects that the two magnetic bodies are stabilized in proper positions and fixed through an upper magnet storage stand and a lower magnet storage stand which are uniquely designed correspondingly, and ultrasonic waves are used for sealing after the magnetic bodies are placed so that the magnetic bodies can be mounted more firmly, cannot be seen or touched by children, and are not prone to falling and safer when played and used.

[0016] A magnetic body automatic-guiding system is formed through interaction of the two magnetic bodies on the upper side and the lower side, and can remind children of the building block mounting sequence. If the direction is correct, the building blocks can be stacked by children easily; if the direction is incorrect, the upper building block and the lower building block with the same pole repulse mutually when placed together, and thus children can also be reminded.

[0017] The building block is different from other building blocks, which only can be connected after being aligned, on the market. The building blocks of the invention can be attached closely and stacked easily through cooperation of the unique appearance design and the magnetic body sleeve, all children under the age of one can enjoy the fun of the building blocks through the mutual attraction function of the magnetic bodies, the building blocks can be played by more people and can even be played by children at the age of about six months, and the inspiration effect is more excellent.

[0018] The building block is low in weight, firm in connection, and more comfortable when held in hands of children.
