Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

As shown in fig. 1 to 9, the embodiment of the present invention discloses a three-order building block magic cube which can be easily disassembled and can be rearranged into a long strip shape by a cubic structure, so that the three-order building block magic cube is stored in a rectangular box, is conveniently stored in a briefcase, a handbag or a pocket, and is conveniently carried when a person goes out.

Referring to fig. 1 to 3, the third-order building block magic cube comprises six center blocks 1, twelve edge blocks 2 and eight corner blocks 3, wherein the center blocks 1, the edge blocks 2 and the corner blocks 3 enclose an inner space, a center frame 4 is arranged in the inner space, and the six center blocks 1 are connected to the center frame 4 through rotating shafts. Specifically, the six central blocks 1 are mounted in the middle of the upper, lower, front, rear, left and right planes of the three-order building block magic cube through rotating shafts. Generally, the rotating shaft is a screw, which is threaded through a hole in the center block 1 and then screwed into a corresponding screw hole in the center frame 4. The six rotating shafts corresponding to the six center blocks 1 can also be divided into three pairs, and the two rotating shafts of each pair are coaxially arranged. Specifically, the two rotating shafts in the up-down direction are coaxially arranged, the two rotating shafts in the front-back direction are coaxially arranged, and the two rotating shafts in the left-right direction are coaxially arranged. The center hole 1, the edge block 2 and the corner block 3 are the existing structures of the three-order magic cube.

The center frame 4 is a spherical structure having four connection posts 41 around its circumference, and a screw hole 42 is formed at the end of each connection post 41. Each connecting post 41 is connected with a rotating shaft. The upper and lower parts of the center frame 4 are provided with insertion holes 43, and the middle part of the center frame 4 is provided with a containing bin 44. The insertion hole 43 may be a hole structure such as a circular hole or a hexagonal hole.

In the third-order building block magic cube of the present invention, one pair of the coaxial shafts is a quick-release shaft, specifically, as shown in fig. 2, fig. 2 shows that the vertical shafts are quick-release shafts, and the quick-release shafts include screws 51 and iron insertion posts 52. The screw is inserted through the center block 1 and then mounted to the first end of the post 52. The second end of the post 52 is inserted into the insertion hole 43 formed in the center frame 4. The insertion hole 43 serves as a positioning function for the insertion post 52, and there is no friction between the two during insertion. The fixed magnet 45 is arranged in the accommodating bin 44, the fixed magnet 45 and the inserting column 52 form a magnetic connecting assembly, and the inserting column 52 is fixed on the central frame 4 through the magnetic attraction effect between the magnetic connecting assemblies. The quick-release type rotating shaft realizes the tool-free quick installation or disassembly of the rotating shaft.

In the quick-release rotating shaft, the screw 51 is connected to the inserting column 52, and the inserting column 52 is inserted into the central frame 4. The rotating shaft on the existing three-order magic cube is only provided with the screw, namely, the rotating shaft is only played through the screw in the prior art, so that when the rotating shaft is disassembled, the screw needs to be disassembled by a screwdriver, and quick disassembly cannot be realized.

When the three-order building block magic cube is used, the quick-release rotating shaft and the central frame 4 can be fixed only by inserting the inserting columns 52 into the inserting holes 43 of the central frame 4. The quick-release type rotating shaft can be quickly and easily separated from the center frame 4 by pulling the inserting column 52 out of the inserting hole 43.

As shown in fig. 4 and 5, after the plug-in post 52 in the quick-release type rotating shaft is quickly removed from the center frame 4 without tools, the center block, the edge block and the corner block surrounding the plug-in post 52 are combined into one row of assemblies 10 and three rows of assemblies 30, and the center frame 4 and the center block and the edge block surrounding the center frame 4 are combined into two rows of assemblies 20, so that the one row of assemblies 10, the two rows of assemblies 20 and the three rows of assemblies 30 can be rearranged, and the three rows of assemblies are arranged into a cuboid structure with the length and width of 9 × 3 × 1 from a cuboid structure with the length and width of 3 × 3 × 3, and the three-step building block magic cube can be stored in a cuboid box similar to a spectacle case, a medicine box and the like, so that the three-step building block magic cube can be conveniently stored in a handbag or a briefcase for convenient carrying when going out.

Although the magnetic connecting assembly between the quick release type rotating shaft and the center frame 4 includes the fixed magnetic block 45 and the ferrous plunger 52 in the present embodiment, the magnetic connecting assembly may have other structures. For example, the post 52 may be a plastic piece, and then an iron block or a magnetic block is embedded or adhered to the second end of the post 52.

As shown in fig. 6 to 9, in the embodiment of the present invention, the positioning magnetic blocks are provided on the inner sides of the invisible outer walls of the prism blocks 2 and the corner blocks 3. When the three-order building block magic cube is in the complete installation state, the outer wall that can not be observed from the outside is the invisible outer wall of arris piece 2 and hornblock 3. Since the bodies of the prism block 2 and the corner block 3 are also of a cubic structure, the prism block 2 has two outer walls exposed to the outside, so that the prism block 2 has four non-visible outer walls, and the corner block 3 has three outer walls exposed to the outside, so that the corner block 3 has three non-visible outer walls. In particular, the block 2 is formed by two completely symmetrical block sections 21 which are fastened together, and a positioning magnet 22 is provided on each block section 21. The corner block 3 is formed by three completely symmetrical corner block subsections 31 which are buckled together, and each corner block subsection 31 is provided with a positioning magnetic block 32. The mode of installing the positioning magnetic blocks on the edge blocks 2 and the corner blocks 3 and the structural form of arranging the positioning magnetic blocks on the edge blocks 2 and the corner blocks 3 belong to the prior art.

After the positioning magnetic blocks are added, the adjacent edge blocks and the adjacent corner blocks can be magnetically connected through the positioning magnetic blocks. When the three-order building block magic cube is rotated, the three-order building block magic cube can be positioned through the positioning magnetic block, the hand feeling during rotation is improved, and the magic cube is automatically aligned. And with the back is torn open to quick detach formula pivot, the one row of subassembly 10 and the three row of subassembly 30 of formation also can be at the attraction of location magnetic path under, be difficult to the frame that looses at the in-process of accomodating into the cuboid box and the in-process of taking out from the cuboid box, further facilitate the use. The edge block 2 and the central block 1 can also be magnetically connected through the positioning magnetic block, and only the positioning magnetic block or the iron sheet is required to be arranged in the central block 1. Thus, the central block 1 can be magnetically connected with the edge block 2 and the corner block 3 into a whole, and is not easy to fall off.

Exemplary embodiments of the present invention are specifically illustrated and described above. It is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
