[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: a magnesia-carbon brick structure with stable connection, comprising a first brick body 1 and a second brick body 2, wherein a connecting plate 3 is fixedly connected to the side wall of the first brick body 1, a receiving groove 4 is opened on the connecting plate 3, and a fixing block 5 is slidably connected to the interior of the receiving groove 4;

[0020] A connecting groove 6 is provided at the position of the second brick body 2 corresponding to the connecting plate 3 , a lifting groove 7 is provided on the second brick body 2 , a lifting plate 8 is slidably connected inside the lifting groove 7 , and a fixing groove 9 is provided inside the second brick body 2 .

[0021] Furthermore, the bottom end of the fixing block 5 is triangularly shaped, and the connection between the fixing block 5 and the receiving groove 4 has friction. The friction between the fixing block 5 and the receiving groove 4 can prevent the fixing block 5 from sliding inside the receiving groove 4 due to gravity.

[0022] Furthermore, the connecting plate 3 is slidably connected inside the connecting groove 6, the top end of the fixed block 5 abuts against the bottom end of the lifting plate 8, and the connection between the lifting plate 8 and the lifting groove 7 has friction. The friction between the lifting plate 8 and the lifting groove 7 can prevent the lifting plate 8 from sliding inside the lifting groove 7 due to gravity.

[0023] Furthermore, a finger pressure groove 10 is provided on the lifting plate 8 , and a symmetrically arranged square groove 11 is provided on the second brick body 2 at a position corresponding to the lifting groove 7 , and the square grooves 11 are in communication with the lifting groove 7 .

[0024] Furthermore, the fixing groove 9 is located at the bottom end of the connecting groove 6 , and the fixing groove 9 , the connecting groove 6 and the lifting groove 7 are in a communicating state.

[0025] Specifically, when using the present invention, hold the first brick body 1 and insert the connecting plate 3 on the first brick body 1 into the corresponding connecting groove 6 on the second brick body 2. When the connecting plate 3 is connected to the connecting groove 6, the bottom end of the lifting plate 8 abuts against the top end of the fixed block 5. At this time, press the lifting plate 8, and the lifting plate 8 slides downward inside the lifting groove 7. The downward sliding of the lifting plate 8 will squeeze the fixed block 5 and move it downward. The fixed block 5 moves downward and is connected to the inside of the fixed groove 9. At this time, the lifting plate 8 has also completely slid into the inside of the lifting groove 7. Figure 4 At this time, the first brick body 1 and the second brick body 2 are connected, and the connection is very strong, and the remaining magnesia carbon bricks are connected in the same way as above;

[0026] When it is necessary to separate the first brick body 1 from the second brick body 2, the finger can be inserted into the finger pressure groove 10 on the lifting plate 8 through the square groove 11, and then the lifting plate 8 can be lifted upward. At this time, the bottom end of the lifting plate 8 is no longer in contact with the top of the fixed block 5. At this time, directly pull the first brick body 1 with force. The first brick body 1 will transmit the pulling force to the connecting plate 3 and the fixed block 5. At this time, the triangular part of the fixed block 5 will be in contact with the corners of the fixed groove 9. At this time, the pulling force will cause the fixed block 5 to be squeezed upward and completely retracted into the accommodating groove 4. At this time, the connecting plate 3 will be separated from the connecting groove 6, and the first brick body 1 and the second brick body 2 are separated.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
