[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A magnesia carbon brick that is easy to splice, comprising an upper magnesia carbon brick module 1, several groups of intermediate magnesia carbon brick modules 2 and a lower magnesia carbon brick module 3. The upper magnesia carbon brick module 1, several groups of intermediate magnesia carbon brick modules 2 and the lower magnesia carbon brick module 3 are arranged in sequence from top to bottom. The upper magnesia carbon brick module 1 is composed of several groups of upper magnesia carbon brick bodies 4. Any group of the several groups of intermediate magnesia carbon brick modules 2 is composed of several groups of intermediate magnesia carbon brick bodies 5. The lower magnesia carbon brick module 3 is composed of several groups of lower magnesia carbon brick bodies 6. The length and width of the upper magnesia carbon brick body 4, the intermediate magnesia carbon brick body 5 and the lower magnesia carbon brick body 6 are equal. Setting the length and width of the upper magnesia carbon brick body 4, the intermediate magnesia carbon brick body 5 and the lower magnesia carbon brick body 6 to be equal can make the overall splicing more regular after completion, which is beneficial to the stability of the brick structure.

[0026] Adjacent groups of the upper magnesia-carbon brick bodies 4, the middle magnesia-carbon brick bodies 5 and the lower magnesia-carbon brick bodies 6 are connected by a connecting positioning assembly 7. A first splicing groove 8 and a second splicing groove 9 are respectively provided on both sides of any group of the upper magnesia-carbon brick bodies 4, the middle magnesia-carbon brick bodies 5 and the lower magnesia-carbon brick bodies 6;

[0027] Among them, the connection positioning assembly 7 is composed of a connection block 71, a first positioning embedded column 72 and a second positioning embedded column 73. The size and shape of the first positioning embedded column 72 and the second positioning embedded column 73 are equal. The first positioning embedded column 72 and the second positioning embedded column 73 are fixedly installed on both sides of the center of the bottom surface of the connection block 71. The volume of the connection block 71 is slightly equal to the sum of the volumes of the first splicing embedded groove 8 and the second splicing embedded groove 9. The inner bottom surfaces of the first splicing embedded groove 8 and the second splicing embedded groove 9 are both provided with a positioning column groove 891. The length of the first positioning embedded column 72 and the second positioning embedded column 73 is equal to the depth of the positioning column groove 891. The first positioning embedded column 72 and the second positioning embedded column 73 are equal to the depth of the positioning column groove 891. The diameter of 3 is slightly equal to the diameter of the positioning column groove 891. When splicing several groups of upper magnesia-carbon brick bodies 4, the connection positioning assembly can be placed at both ends between any two adjacent groups, and the first positioning embedded column 72 and the second positioning embedded column 73 are inserted into the interior of the positioning column groove 891. At this time, the connection embedded block 71 is embedded and installed in the first splicing embedded groove 8 and the adjacent second splicing embedded groove 9. The operation method for splicing several groups of intermediate magnesia-carbon brick bodies 5 and several groups of lower magnesia-carbon brick bodies 6 is the same as above. In this way, by improving the structure of existing magnesia-carbon bricks, convenient splicing can be achieved, dislocation can be effectively prevented, and the stability of the brick body and convenience of use are ensured;

[0028] In addition, in this embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The first splicing groove 8 is located at both ends of the same side of the upper magnesia carbon brick body 4, the middle magnesia carbon brick body 5, and the lower magnesia carbon brick body 6, and the second splicing groove 9 is located at both ends of the other side of the upper magnesia carbon brick body 4, the middle magnesia carbon brick body 5, and the lower magnesia carbon brick body 6. The position design of the first splicing groove 8 and the second splicing groove 9 can further improve the stability after splicing;

[0029] In addition, in this embodiment, please refer to Figure 2 、 Figure 3 and Figure 4The bottom surfaces of the upper magnesia-carbon brick body 4 and the middle magnesia-carbon brick body 5 are fixedly installed with lower splicing positioning blocks 451, and the top surfaces of the middle magnesia-carbon brick body 5 and the lower magnesia-carbon brick body 6 are provided with upper splicing positioning grooves 561 adapted to the lower splicing positioning blocks 451. The design of the lower splicing positioning blocks 451 and the upper splicing positioning grooves 561 can be used to stack several groups of upper magnesia-carbon brick bodies 4, several groups of middle magnesia-carbon brick bodies 5, and several groups of lower magnesia-carbon brick bodies 6. The stacking and splicing are performed by stacking and splicing several groups of lower splicing positioning blocks 451 on the bottom surfaces of the upper magnesia-carbon brick bodies 4 and several groups of upper splicing positioning grooves 561 on the top surfaces of the middle magnesia-carbon brick bodies 5. At the same time, the stacking and splicing are performed by stacking and splicing several groups of lower splicing positioning blocks 451 on the bottom surfaces of the middle magnesia-carbon brick bodies 5 and the upper splicing positioning grooves 561 on the top surfaces of the lower magnesia-carbon brick bodies 6, thereby realizing rapid stacking and splicing, further improving the convenience of splicing the overall structure, and ensuring the flatness of the overall structure after stacking and splicing.

[0030] In addition, in this embodiment, please refer to Figure 2 、 Figure 3 and Figure 4 The cross sections of the lower splicing positioning block 451 and the upper splicing positioning groove 561 are both arranged in an inverted trapezoidal shape.

[0032] In this embodiment, the implementation scenario is specifically as follows: when splicing several groups of upper magnesia carbon brick bodies 4, the connection positioning components can be placed at the two ends between any two adjacent groups, and the first positioning embedded column 72 and the second positioning embedded column 73 are inserted into the interior of the positioning column groove 891. At this time, the connection embedded block 71 is embedded and installed in the first splicing embedded groove 8 and the adjacent second splicing embedded groove 9. When splicing several groups of intermediate magnesia carbon brick bodies 5 and several groups of lower magnesia carbon brick bodies 6, the operation method is the same as above, and the lower splicing positioning blocks 451 on the bottom surface of several groups of upper magnesia carbon brick bodies 4 can be connected with several groups. The upper splicing positioning groove 561 on the top surface of the middle magnesia carbon brick body 5 is stacked and spliced, and at the same time, several groups of lower splicing positioning blocks 451 on the bottom surface of the middle magnesia carbon brick body 5 and the upper splicing positioning groove 561 on the top surface of the lower magnesia carbon brick body 6 are stacked and spliced. At the same time, the connecting block 71 can be accurately cut in half through the center dividing line 711, so that the first splicing groove 8 and the second splicing groove 9 at the corners can be filled. By improving the structure of the existing magnesia carbon brick as a whole, it can achieve convenient splicing and effectively prevent dislocation, ensuring the stability of the brick body and the convenience of use.
