[0042] like Figures 1 to 6 As shown, an embodiment of the present application provides a magnetic building block assembly 100, comprising: a central tube 1, a middle shell 2, and two end shells 3. The central tube 1 is provided with first flat surfaces 11 at both ends along the length direction. The two first flat surfaces 11 are provided on opposite sides of the central tube 1 and are parallel to each other. The middle shell 2 is rotatably mounted on the central tube 1. A magnetic attraction component a is provided on the middle shell 2. The middle shell 2 can rotate freely under the action of an external force, achieving a stress-relieving and entertaining effect and facilitating contact with other building blocks. The two end shells 3 have the same structure. The end shells 3 have a sleeve 33, and the inner wall of the sleeve 33 has a second flat surface 331. The end shells 3 are provided with an insertion shaft 35 and a slot 34. The two end shells 3 are respectively connected to the two ends of the center tube 1. When the end shells 3 are connected to the center tube 1, the sleeve 33 of the end shell 3 is sleeved on the center tube 1, and the second flat surface 331 on the sleeve 33 is in contact with the first flat surface 11 on the center tube 1. In the two end shells 3, the extension line of each insertion shaft 35 of one passes through each slot 34 of the other, that is, the installation directions of the two end shells 3 are opposite. The two end shells 3 at both ends of the magnetic building block assembly 100 are installed in opposite directions, so that any two of the multiple magnetic building block assemblies 100 can be successfully spliced.

[0043] The magnetic building block assembly 100 of the present application can limit the installation direction of the two end shells 3 by respectively providing the first flat surfaces 11 at both ends of the central tube 1, so that the two end shells 3 are in opposite directions after installation, which is convenient for splicing with other magnetic building block assemblies 100 and convenient for use.

[0044] In some possible implementation schemes, the end shells 3 are sequentially provided with a plurality of side planes along the circumferential direction. When the two end shells 3 are respectively connected to the two ends of the central tube 1, the side planes of the two end shells 3 are opposite to each other, and the opposite side planes are located in the same plane, that is, the two end shells 3 at both ends of the magnetic building block assembly 100 are fixed relative to the central tube 1 and cannot rotate, while the middle shell 2 located between the two end shells 3 can rotate freely.

[0045] In some possible embodiments, two protrusions 31 and two recesses 32 are provided on the top of the end shell 3. The two protrusions 31 are located on both sides of the end shell 3 along one diagonal line, and the two recesses 32 are located on both sides of the end shell 3 along the other diagonal line. The protrusions 31 are provided with the slots 34, and the recesses 32 are provided with the insertion shafts 35. When two magnetic building block assemblies 100 are spliced together, the two end shells 3 with different installation directions are spliced together, and the protrusions 31 of one are embedded in the recesses 32 of the other.

[0046] In some possible embodiments, the magnetic building block assembly 100 includes a bearing 4, which is sleeved on the central tube 1, and the middle shell 2 is sleeved on the bearing 4. The provision of the bearing 4 reduces the frictional resistance between the middle shell 2 and the central tube 1, which facilitates the smooth and rapid rotation of the middle shell 2 under the action of an external force, thereby achieving a stress-relieving and entertaining effect.

[0047] In some possible embodiments, the middle shell 2 includes a cylindrical shell portion 21 and two end covers 22. The inner side of the cylindrical shell portion 21 has an annular sleeve 211, and the annular sleeve 211 is sleeved on the bearing 4. The two end covers 22 are connected to the cylindrical shell portion 21, and the two end covers 22 are limited to both sides of the bearing 4.

[0048] Specifically, the end cover 22 includes a cover body and a collar 221 disposed on the cover body. The cover body is connected to the cylindrical shell 21. The collar 221 extends into the inner side of the cylindrical shell 21 and is located on one side of the bearing 4. The collars 221 of the two end shells 3 are located on both sides of the bearing 4.

[0049] In some possible implementations, the magnetic building block assembly 100 includes a plurality of magnetic components a, each of which is disposed at a corner of the middle shell 2. The middle shell 2 is generally a cube or a rectangular parallelepiped structure, and a magnetic component a is disposed at each of the eight vertices of the middle shell 2.

[0050] In some possible implementation schemes, a first recessed groove is provided on each corner of the cylindrical shell portion 21, and a second recessed groove is provided on each corner of the end cover 22. When the end cover 22 is connected to the cylindrical shell portion 21, each first recessed groove is respectively connected to the corresponding second recessed groove to form a accommodating cavity for accommodating the magnetic attraction component a.

[0051] The magnetic component a is a sphere. The spherical magnetic component a is compact, occupies minimal space, and is easy to assemble. The magnetic component a can rotate freely within the accommodating cavity and automatically adjust the magnetic pole position based on external magnetic forces.

[0052] The present application also provides a magnetic building block toy, such as Figure 6 As shown, the toy includes multiple magnetic building block assemblies 100 described above. In each of the magnetic building block assemblies 100, the end shell 3 on one can be plugged into and matched with the end shell 3 of another. The magnetic building block toy can also include a square-shaped magnetic block 200, which is comparable in size to the middle shell 2 or the two spliced end shells 3. Each of the eight corners of the magnetic block 200 is provided with a receiving cavity for accommodating the magnetic component a. When a flat surface of the magnetic block 200 is in contact with an outer wall surface of the middle shell 2, the four opposing magnetic components a on the two are magnetically attracted to each other.

[0053] like Figure 7 As shown, the magnetic block 200 can include two half-shells, each of which is provided with a plurality of pins 210 and inserts 220. When the two half-shells are engaged, the pins 210 of one are inserted into the inserts 220 of the other. Grooves are provided at the corners of the openings of the two half-shells. When the two half-shells are engaged, the opposing grooves are connected to accommodate the magnetic component a. The magnetic block 200 also includes a connecting shaft 240. A mating sleeve 230 is provided at one end of the half-shell facing the opening. The mating sleeve 230 can accommodate a magnetic component a. The connecting shaft 240 is inserted into the mating sleeves 230 on each of the two half-shells.

[0054] The preferred embodiments of the present application disclosed above are intended only to help illustrate the present application. The preferred embodiments do not describe all details in detail, nor do they limit the present application to the specific embodiments described. Obviously, many modifications and variations can be made based on the content of this specification.
