For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Example 1: See Figures 1 to 3As shown, the first embodiment of the present application provides a corner block, including: a main shell 1 and a foot piece 2. The main shell 1 includes three shells 11, the shell 11 has a plug-in shell portion 111, the plug-in shell portion 111 has a slot 1111, a first snap-fit ​​plate 112 and a second snap-fit ​​plate 113 are arranged on the shell 11, the first snap-fit ​​plate 112 and the second snap-fit ​​plate 113 are arranged on both sides of the plug-in shell portion 111, and a snap-in 1121 is arranged on the first snap-fit ​​plate 112, and a snap-in protrusion 1131 is arranged on the second snap-fit ​​plate 113. The three shells 11 are arranged in sequence, and the three shells 11 are enclosed to form a cavity, and the first snap-fit ​​plate 112 of one of the two adjacent shells 11 is attached to the second snap-fit ​​plate 113 of the other, and the snap-in protrusion 1131 on the second snap-fit ​​plate 113 is snap-fitted to the snap-in 1121 on the first snap-fit ​​plate 112. A plurality of plug-in plates 21 are provided at one end of the foot member 2, and each of the plug-in plates 21 is respectively inserted into the corresponding slot 1111 of the main shell 1, and the other end of the foot member 2 extends out of the main shell 1 and is provided with a foot piece 22. The corner block of the present application is provided with a first snap-fit ​​plate 112 and a second snap-fit ​​plate 113 on the shell 11 on the basis of retaining the original connection mode of inserting the plug-in plate 21 into the slot 1111, and the first snap-fit ​​plate 112 of one of the two adjacent shells 11 is attached to the second snap-fit ​​plate 113 of the other, and the snap-fit ​​protrusion 1131 on the second snap-fit ​​plate 113 is snap-fitted to the snap-fit ​​port 1121 on the first snap-fit ​​plate 112, and further connection and fixation of the two adjacent shells 11 is achieved through this double snap-fit ​​mode. The connection strength between the shells 11 of the corner block is effectively enhanced, and the risk of the corner block loosening and falling off when the magic cube is impacted by external force is greatly reduced, making the overall structure of the magic cube more stable and durable, and having a longer service life.

[0046] The bayonet 1121 is disposed on a side of the first snap-fitting plate 112 away from the housing 11, and the snap-fitting protrusion 1131 is protruded from a side of the second snap-fitting plate 113 away from the housing 11. The bayonet 1121 of the first snap-fitting plate 112 of one of the two adjacent housings 11 is close to the snap-fitting protrusion 1131 of the second snap-fitting plate 113 of the other, so that the snap-fitting protrusion 1131 is snapped into the bayonet 1121, thereby facilitating connection and fixation.

[0047] The first snap-fit ​​plate 112 is provided with a first reinforcing rib 1122, and the first reinforcing rib 1122 is connected to the housing 11. The second snap-fit ​​plate 113 is provided with a second reinforcing rib 1132, and the second reinforcing rib 1132 is connected to the housing 11. The first reinforcing rib 1122 is located on a first side of the first snap-fit ​​plate 112 along the thickness direction, and the second reinforcing rib 1132 is located on a second side of the second snap-fit ​​plate 113 along the thickness direction. The first reinforcing rib 1122 increases the structural strength of the first snap-fit ​​plate 112, making it less susceptible to damage. The second reinforcing rib 1132 increases the structural strength of the second snap-fit ​​plate 113, making it less susceptible to damage. The first side and the second side are the upper side and the lower side of the first snap-fit ​​plate 112 and the second snap-fit ​​plate 113 in the thickness direction. When the first snap-fit ​​plate 112 of one of the two adjacent shells 11 is attached to the second snap-fit ​​plate 113 of the other, the arrangement positions of the first reinforcement rib 1122 and the second reinforcement rib 1132 will not interfere with the attachment of the first snap-fit ​​plate 112 and the second snap-fit ​​plate 113.

[0048] A clamping plate 114 is provided on the shell 11, and the clamping plate 114 is located on one side of the second snap-fitting plate 113 along the thickness direction. In two adjacent shells 11, the first snap-fitting plate 112 of one is inserted between the second snap-fitting plate 113 and the clamping plate 114 of the other, and a limiting fitting structure is added to effectively prevent the snap-fitting protrusion 1131 from easily detaching from the snap-fitting port 1121.

[0049] The housing 11 is provided with a snap-in groove 1151 and a snap-in plate 116 on both sides. The snap-in plate 116 on one of the two adjacent housings 11 is inserted into the snap-in groove 1151 of the other. The housing 11 is provided with a plug-in mating shell 115, and the plug-in mating shell 115 has the snap-in groove 1151. The snap-in plate 116 is inserted into the snap-in groove 1151, so that the gap of the assembled main housing 1 is smooth without forming unevenness.

[0050] The housing 11 has an exposed sheet 117 and a contact sheet 118, and the contact sheet 118 is connected to the exposed sheet 117. When the magic cube is in a reset state, the exposed sheet 117 is exposed on the surface of the magic cube, and the contact sheet 118 is in contact with the adjacent magic cube blocks, wherein the contact sheet 118 is provided with a magnetic component 3. Each of the contact sheets 118 is provided with a magnetic component 3. The magnetic component 3 is opposite to the magnetic component 3 on the housing 11 that is in contact with the adjacent corner blocks, and is magnetically attracted to each other, which has the effect of assisting positioning and smooth hand feeling when rotating and resetting.

[0051] The inner wall of the contact piece 118 is provided with a groove 1181, and the inner wall of the contact piece 118 is provided with a cover 1182, and the groove 1181 is located inside the cover 1182. The magnetic component 3 is located inside the cover 1182, and the magnetic component 3 is partially embedded in the groove 1181. The magnetic component 3 can be a magnet, and the shape of the magnet can be a round cake. The groove 1181 facilitates the embedding of the magnet and plays a role in positioning. The magnet can be fixed in the groove 1181 by colloid bonding. The bonding method is convenient to install and has a simpler structure. When the magnet is installed by colloid, the cover 1182 plays a role in guiding the colloid and preventing the colloid from leaking out.

[0052] The housing 11 is provided with a reinforcing rib plate 119, which is connected to the plug-in shell 111, and is provided with an escape notch 1191 for escaping the clamping foot 2. The reinforcing rib plate 119 increases the structural strength of the plug-in shell 111, so that the plug-in shell 111 is not easily broken or damaged during plugging.

[0053] Along the length direction of the foot piece 2, the width of the plug shell 111 gradually decreases, and the width of the plug plate 21 gradually decreases. The plug shell 111 and the plug plate 21 can adapt to the structure of the corner block and can be plugged together to fix the three housings 11.

[0054] Example 2: See Figure 4 and Figure 5 As shown, the second embodiment of the present application also provides a second-order Rubik's Cube, including: a central body 4, a central block 5, a plurality of hidden blocks 6 and corner blocks as in the first embodiment. The central body 4 has a plurality of central axes. The central block 5 is connected to the central axis. Each of the hidden blocks 6 is located on the peripheral side of the central block 5. Each of the corner blocks is located on the outside of the central block 5 and the hidden block 6, and the foot piece 22 at the end of the foot piece 2 of each corner block is located on the inside of the hidden block 6 and the central block 5. The second-order Rubik's Cube of the present application has 4 corner blocks, and the connection strength between the shells 11 of the corner blocks greatly reduces the risk of the corner blocks becoming loose or falling off when the Rubik's Cube is impacted by external forces, making the overall structure of the Rubik's Cube more stable and durable, and having a longer service life.
