Abstract

The present application discloses a magnetic building block, comprising: a main housing, a plurality of magnet housings and two cover bodies. The main housing comprises a cylinder housing and a partition plate, the cylinder housing has a cavity and two openings, the partition plate is located within the cavity, and the partition plate is provided with a main stiffener structure group. The magnet housings are respectively connected to the partition plate and an inner wall of the cylinder housing, and magnet grooves are formed among the magnet housings, the partition plate and the cylinder housing. Surfaces of the two cover bodies are respectively provided with a cover stiffener structure group, and the cover bodies cover the openings and each of the magnet grooves in a state where the cover bodies are connected to the main housing.

What is claimed is: 
     
         1 . A magnetic building block, comprising:
 a main housing, the main housing comprising a cylinder housing and a partition plate, the cylinder housing having a cavity and two openings communicating with the cavity, the partition plate being located within the cavity, a peripheral edge of the partition plate being connected to an inner wall of the cylinder housing, and the partition plate being provided with a main stiffener structure group;   a plurality of magnet housings, the magnet housings being respectively connected to the partition plate and the inner wall of the cylinder housing, magnet grooves being formed among the magnet housings, the partition plate and the cylinder housing, and each of the magnet housings being fixedly connected to the main stiffener structure group;   two cover bodies, surfaces of the two cover bodies being respectively provided with a cover stiffener structure group, the two cover bodies being respectively detachably connected to the main housing, and the cover bodies covering the openings and each of the magnet grooves in a state where the cover bodies are connected to the main housing; and   connecting cylinders, the connecting cylinders being arranged on an inner wall of the main housing, the cover bodies being respectively provided with an insertion post for inserting into the connecting cylinder, and the connecting cylinders being connected to the main stiffener structure group; and   wherein the main stiffener structure group comprises a plurality of first stiffeners, and the first stiffeners are connected between two adjacent magnet housings in a circumferential direction of the main housing.   
     
     
         2 . The magnetic building block according to  claim 1 , wherein each of the connecting cylinders is respectively located between two adjacent magnet housings; and
 the main stiffener structure group comprises a plurality of second stiffeners, one end of each of the second stiffeners is connected to the connecting cylinder, and the other end thereof is connected to a corresponding first stiffener.   
     
     
         3 . The magnetic building block according to  claim 2 , wherein the main stiffener structure group comprises a convex ring and a plurality of third stiffeners, and the convex ring is located in the middle of an area enclosed by each of the first stiffeners; and
 one end of each of the third stiffeners is connected to the convex ring, and the other end thereof is connected to a corresponding magnet housing.   
     
     
         4 . The magnetic building block according to  claim 3 , wherein the magnet housings each comprise two flat plates and an arc-shaped plate connecting the two flat plates, the two flat plates are respectively connected to the inner wall of the cylinder housing; and
 a magnet is freely movably arranged within the magnet groove.   
     
     
         5 . The magnetic building block according to  claim 1 , wherein the cover stiffener structure group comprises a plurality of fourth stiffeners provided at edges of the cover bodies; and
 each of the insertion posts is respectively connected to a corresponding fourth stiffener.   
     
     
         6 . The magnetic building block according to  claim 5 , wherein the cover stiffener structure group comprises a plurality of fifth stiffeners; and
 the fifth stiffener is connected between two adjacent fourth stiffeners, and each of the fifth stiffeners is connected end to end in sequence to form a closed ring.
