[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: a magnesia-carbon brick convenient for splicing, including a brick body 1. A sealing groove 5 is opened on the back of the upper end of the brick body 1, and a sealing strip 6 is fixedly connected to the back of the lower end of the brick body 1. Two first card slots 2 are symmetrically opened up and down in the middle of the front of the brick body 1. Both of the two first card slots 2 are in a T-shaped structure and the vertical parts face away from each other. A connection block 4 is clamped in the first card slot 2 located below. The connection block 4 is in an I-shaped structure, and the lower end of the connection block 4 extends to the outside of the brick body 1. The part of the connection block 4 located outside the brick body 1 matches the size of the first card slot 2. A second card slot 7 is opened on the front of one side of the brick body 1, and a clamping plate 9 is fixedly connected to the front of the other side of the brick body 1. The size of the clamping plate 9 matches the size of the second card slot 7.

[0018] A clamping block 8 is fixedly connected to the inner wall of the middle part of the second card slot 7 facing the front. A third card slot 10 is formed in the middle of the back surface of the card board 9. The size of the third card slot 10 matches the size of the clamping block 8, which is convenient for embedding the card board 9 in the second card slot 7. Friction grooves 3 are formed in the inner walls of the horizontal parts of the two first card slots 2, and the friction grooves 3 are opposite to the vertical parts of the corresponding first card slots 2 respectively, which is convenient for the staff to grasp the brick body 1. The thickness between the upper and lower ends and the thickness between the front and rear sides of the sealing strip 6 respectively match the distance between the upper and lower ends and the distance between the front and rear sides of the sealing groove 5.
