In order to solve the problem, the magnets are placed in the building blocks, the connection among the building blocks is enhanced by utilizing the attraction among the magnets, and the building block model which is built for a long time is prevented from banging and collapsing due to the fact that the building blocks are touched carelessly. But new problems also follow: the magnets arranged in the building blocks are generally dipolar magnets with S poles (south poles) and N poles (north poles) which are half-divided, when the building blocks are spliced or stacked, when one building block is required to be stacked on the other building block, one end of each of the two building blocks is S poles or N poles, and under the influence of the same poles of the magnets which repel each other, the end of each of the two building blocks cannot be stacked or spliced, so that the building blocks cannot be stacked according to own ideas at first time, one building block must be rotated by 180 degrees to enable the end of one building block to be positioned at the S pole and the end of the other building block to be positioned at the N pole, and then the building blocks are stacked.

Patent document (CN 201320868075.2) provides a magnetic building block to solve this problem, and the utility model comprises a building block housing, the building block housing has a cavity, a ball-type ball magnet is arranged in the cavity, the ball magnet can freely rotate in the cavity. When the same poles repel each other, the spherical ball magnet automatically rotates in the cavity under the action of magnetic force to adapt to the opposite attraction state. The utility model discloses a can solve the problem of above-mentioned description better, but this utility model also has the weak point: because of the magnet shape is the ball-type, two when the magnetism building blocks paste, arrange two in the magnetism building blocks two ball-type ball magnet only attracts each other with minimum region, and magnetic adsorption power is limited, when piecing together great magnetism building blocks, because partly or be in the unsettled state of one end of building blocks combination, then the magnetic force building blocks in the similar rectangular shape building blocks combination of this part easily drop, want to avoid this condition, must use more magnetism building blocks or make the size grow of each ball-type ball magnet, after the size grow of each ball-type ball magnet, the size of magnetism building blocks just needs the grow. If the scheme of using more magnetic building blocks is adopted, the experience of the user is reduced, and the user has to use more magnetic building blocks in order to piece up the model required by the user; if the scheme that the size of each spherical ball magnet is increased is adopted, the production cost is increased, and the weight of each magnetic building block is increased. The reason for the above disadvantages is that the shape of the magnet is spherical, and the spherical magnet is a necessary feature of the utility model to avoid the repulsion of like poles, which is difficult to avoid.

Therefore, the magnetic building block with the rotatable magnet, which does not need to be turned in angle and has strong adsorption capacity, is needed when being assembled.

The rotation process from repulsion to attraction of the two magnets 30 is as follows: initially, the magnets 30 are subjected to a repulsive force, the bottom walls of the magnets 30 abut against the bottom walls of the accommodation holes 201, and at the same time, the magnets 30 are rotated by a predetermined angle about the central axes of the magnets 30; during the rotation of the magnets 30, the attractive force between the magnets 30 increases, and eventually, the top wall of the magnets 30 comes into contact with the housing cover 40. This process is very short, and the user only feels the repulsive force between the magnets 30 at a moment, and the influence on the user experience is small.

Description of drawings fig. 2 shows a second embodiment of the present application, in which each of the magnets 30 has a through hole 301 in the center thereof so that the magnets 30 are circular. Through the through hole 301, the contact area between the magnet 30 and the bottom wall of the accommodating hole 201 and the housing cover 40 is reduced, the material used for the magnet 30 is saved, and the production cost is reduced. In order to secure the attraction force of the magnetic blocks, the diameter of the through hole 301 is smaller than the radius of the magnet 30. In addition, in this embodiment, the rotation process from repulsion to attraction of the two magnets 30 is the same as that of the previous embodiment, and the diameter and height of the magnets 30 are the same as those of the previous embodiment.

It should be noted that, in the radial direction of the rotating shaft 50, the distance between at least two points on the cross-section of the limiting member 60 is greater than the diameter of the concave hole. The manner of placing the boss 601 in the connection hole 502 is not limited to screw connection, plug connection, or adhesive connection. In this embodiment, the material of the limiting member 60 is selected from rubber, and the boss 601 is plugged into the connection hole 502, at this time, the boss 601 is in interference fit with the connection hole 502. The threaded connection is not selected because the connection hole 502 is small; the bonding connection is not selected because the bonding efficiency by glue is lower than the efficiency of plugging the boss 601 into the connection hole 502, and the plugging saves glue. In addition, the height of the stopper 60 is less than one fifth of the height of the magnets 30, so as to avoid the phenomenon of small magnetic attraction force caused by the distance between two magnets 30 when the two magnets 30 are adsorbed by the building blocks.

The magnet 30 is placed between the support portion 501 and the stopper 60 by the support portion 501 and the stopper 60, when the magnet 30 rotates in the housing hole 201, the top wall of the magnet 30 is no longer in contact with the housing cover 40, the bottom wall of the magnet 30 is no longer in contact with the bottom wall of the housing hole 201, the translational range of the magnet 30 in the housing hole 201 is reduced, the contact area between the bottom wall of the magnet 30 and the support portion 501 is smaller than the contact area between the bottom wall of the magnet 30 and the bottom wall of the housing hole 201 in the first two embodiments, the contact area between the top wall of the magnet 30 and the stopper 60 is smaller than the contact area between the top wall of the magnet 30 and the housing cover 40 in the first two embodiments, and the magnet 30 can more stably rotate in the housing hole 201.

In this embodiment, the diameter of the magnet 30 is smaller than that of the accommodating hole 201, and the height of the magnet 30 is smaller than the distance between the supporting portion 501 and the boss connecting portion of the stopper 60.
