[0024] The first plug block 2 and the first slot 3 are arranged to cooperate with each other, and the second plug block 4 and the second slot 5 are arranged to cooperate with each other. When multiple brick bodies 1 are connected, the first plug block 2 of one brick body 1 is connected to the first slot 3 of another brick body 1, and the second plug block 4 of one brick body 1 is connected to the second slot 5 of another brick body 1. Through the arrangement of the first plug block 2, the first slot 3, the second plug block 4 and the second slot 5, the connection between the multiple brick bodies 1 is more convenient, and it is also convenient to align the first connecting holes 6 and the second connecting holes 7 on the multiple brick bodies 1 with each other.

[0025] Two groups of the first connection holes 6 and the second connection holes 7 are provided. The first connection holes 6 penetrate the upper end surface and the lower end surface of the brick body 1, and the second connection holes 7 penetrate the left end surface and the right end surface of the brick body 1. In this device, after the multiple brick bodies 1 are spliced ​​with each other, the first connection holes 6 and the second connection holes 7 on the multiple brick bodies 1 are aligned with each other, and fixing ribs can be inserted into the first connection holes 6 and the second connection holes 7 respectively. The fixing ribs connect the multiple brick bodies 1 together and play an auxiliary fixing role, so that the multiple brick bodies 1 are connected together, and the strength of the brick surface composed of the multiple brick bodies 1 is strengthened. The ends of the fixing ribs can be fixed to the ground.

[0026] A telescopic rod 13 and a sleeve 14 are sleeved on the outer side of the first spring 12, and the telescopic rod 13 and the sleeve 14 are fixedly connected to the splint 11 and the mounting seat 10 respectively. One end of the first spring 12 is fixedly connected to the splint 11, and the other end of the first spring 12 is fixedly connected to the mounting seat 10. Through the action of the first spring 12, the splint 11 can be telescoped.

[0027] There are two groups of splints 11, which are symmetrically arranged on both sides of the mounting base 10. The lower ends of the two groups of splints 11 are fixedly connected with support bars 15, and the upper ends of the two groups of splints 11 are provided with first inclined surfaces 16. The middle parts of the two groups of splints 11 can be clamped with heat insulation boards, which are made of asbestos material. The heat insulation boards are slid between the two splints 11 through the first inclined surfaces 16. The support bars 15 at the lower ends of the splints 11 support the bottom surfaces of the heat insulation boards. In addition, the first springs 12 on the outer sides of the splints 11 squeeze the splints 11 to complete the clamping of the heat insulation boards. The setting of the first springs 12 is suitable for clamping heat insulation boards of different thicknesses.

[0028] There are two groups of cavities 8, which are symmetrically arranged on both sides of the first plug block 2 and the first slot 3. A mounting hole is arranged in the mounting seat 10, and a plug rod 19 is fixedly connected to the mounting hole of the mounting seat 10 through a second spring 18. A plug hole 20 that cooperates with the plug rod 19 is opened in the mounting groove 9, and a second inclined surface 17 is arranged on the end surface of the mounting groove 9. The plug hole 20 in the mounting groove 9 passes through the brick body 1 and is connected to the outside world. An auxiliary rod from the outside can enter the plug hole 20, and the plug rod 19 is pushed out of the plug hole 20, so that the mounting seat 10 can be taken out of the mounting groove 9. When installing the mounting seat 10, the device aligns the plug rod 19 of the mounting seat 10 with the second inclined surface 17 on the surface of the mounting groove 9 and slides it in. During the sliding process, the second spring 18 is compressed. When the plug rod 19 slides to the position of the plug hole 20, the second spring 18 drives the plug rod 19 to be inserted into the plug hole 20, thereby completing the fixation between the mounting seat 10 and the mounting groove 9.

[0029] Working principle of the utility model: when the device is in use, the first plug block 2, the first slot 3, the second plug block 4 and the second slot 5 are set to quickly connect multiple brick bodies 1, and the connected multiple brick bodies 1 form a brick surface. In order to strengthen the strength of the brick surface, fixed ribs can be inserted into the first connecting hole 6 and the second connecting hole 7 respectively. In addition, each brick body 1 of the device is provided with two cavities 8. The setting of the cavity 8 can not only effectively reduce the amount of brick body 1 material used, but also the cavity 8 of the brick body 1 can effectively reduce the amount of brick body 1 material used. The cavity 8 of the brick body 1 can also enhance the heat insulation effect. Again, the mounting seat 10 is connected to the mounting seat 10 through the insertion rod 19, and the clamping plate 11 is connected to the mounting seat 10 through the first spring 12. The clamping plate 11 can be extended and retracted to clamp insulation boards of different thicknesses. The setting of the insulation board further enhances the overall heat insulation effect of the brick body 1. In addition, the first inclined surface 16 at the upper end of the clamping plate 11 facilitates the insulation board to enter between the two clamping plates 11, and the support bar 15 at the lower end of the clamping plate 11 can support the insulation board to improve the stability of the insulation board.
