The present invention provides the following embodiments.

[0027] like Figure 1As shown, it is a schematic diagram of a special-shaped refractory brick structure of a preferred embodiment of the present invention. In the special-shaped refractory brick structure of this embodiment, a plug-in inner groove 101 is provided on one side of the refractory brick body 100, and one side of the plug-in inner groove 101 penetrates the refractory brick body 100, and a plug-in protrusion 102 is fixedly connected to the other side of the refractory brick body 100, and the plug-in protrusion 102 is inserted into the inside of the plug-in inner groove 101. In this embodiment, the plug-in protrusion 102 is inserted into the inside of the plug-in inner groove 101, so that the two adjacent refractory brick bodies 100 can be plugged and fitted with each other.

[0028] like Figure 2 as well as Figure 3 As shown, it is a schematic diagram of the internal structure of the triangular block inserted into the limit groove in this embodiment. A plurality of snap-in flanges 103 are fixedly connected to the interior of the plug-in inner groove 101, and a gap is provided between every two snap-in flanges 103. A plurality of plug-in blocks 108 are fixedly connected to the outer wall of the plug-in protrusion 102, and each plug-in block 108 is inserted into the interior of each gap. In this embodiment, the plug-in block 108 is moved through one side of the opening of the plug-in inner groove 101 to insert the plug-in block 108 into the interior of the gap between every two snap-in flanges 103. By inserting the plug-in block 108 into the interior of the gap, the refractory brick bodies 100 on both sides can be fitted together.

[0029] like Figure 3 as well as Figure 4 As shown, in order to ensure that the two adjacent refractory brick bodies 100 can be relatively fixed after being plugged in, in this embodiment, each clamping flange 103 is provided with inclined chamfers 104 on both sides near the inner wall of the plug-in inner groove 101, and the gap between each two adjacent clamping flanges 103 and the inclined chamfers 104 form a limiting groove 105, and the end of the plug-in block 108 is fixedly connected to a triangular block 109, and one side of multiple triangular blocks 109 is fixedly connected to a vertical flange 107. In this embodiment, multiple triangular blocks 109 are inserted into the interior of each limiting groove 105 from one side of the plug-in inner groove 101. Through the limitation between the triangular block 109 and the limiting groove 105, the two refractory brick bodies 100 can only be pulled out from the opening of the plug-in inner groove 101, and then the two refractory brick bodies 100 can be limited, and the vertical flange 107 can block the opening of the plug-in inner groove 101, so that the connection is smoother and the integrity is better.

[0030] like Figure 3 as well as Figure 4 As shown, the plug-in block 108 and the triangular block 109 are smaller than the size of the limiting groove 105 , and the concrete is poured into the inner groove 101 to squeeze out the plug-in block 108 and the triangular block 109 when inserted, thereby fixing the two refractory brick bodies 100 .

[0031] It is worth noting that the above-mentioned triangular block 109 and inclined chamfer 104 are the limiting components in this embodiment. The limiting components include but are not limited to the triangular block 109 and inclined chamfer 104. As long as it is a component that can insert the plug-in block 108 into the gap between the adjacent two side snap-fit ​​flanges 103 and fix it, it can be applied to this embodiment.

[0032] like Figure 1 as well as Figure 4 As shown, it is a schematic diagram of the internal structure of the storage rod and the extension rod inserted into the limiting hole in this embodiment, a through hole 110 is provided on the plug-in protrusion 102, and limiting holes 106 are provided on the inner walls on the upper and lower sides of the plug-in inner groove 101, a storage rod 111 is inserted into the through hole 110, and the extension rod 112 is slidably connected inside the storage rod 111, and a spring is provided between the storage rod 111 and the extension rod 112, and the spring causes the extension rod 112 to extend out of the storage rod 111. In this embodiment, when the plug-in protrusion 102 is inserted into the inner plug-in groove 101, the storage rod 111 and the extension rod 112 are first manually pressed to retract. As the plug-in protrusion 102 is inserted and the storage rod 111 and the extension rod 112 are aligned with the limiting hole 106, the spring can automatically reset and extend, thereby enabling the storage rod 111 and the extension rod 112 to be inserted into the limiting hole 106, thereby fixing the two refractory brick bodies 100.

[0033] It is worth noting that the above-mentioned storage rod 111 and extension rod 112 are fixing components in this embodiment, and the fixing components include but are not limited to the above-mentioned storage rod 111 and extension rod 112. As long as it is a component that can fix two refractory brick bodies 100, it can be applied to this embodiment.

[0034] In summary, the specific use of this embodiment is as follows:

[0035] First, pour concrete into the inner groove 101 on one of the refractory brick bodies 100, shrink the storage rod 111 and the extension rod 112 on the other refractory brick body 100, and insert the plug-in protrusion 102, the plug-in block 108 and the triangular block 109 into the inner limit groove 105. The two refractory brick bodies 100 are pre-fixed by the limit between the triangular block 109 and the limit groove 105. As the plug-in protrusion 102 is inserted into the storage rod 111 and the extension rod 112, the plug-in protrusion 102, the plug-in block 108 and the triangular block 109 are inserted into the inner limit groove 105. When aligned with the limiting hole 106, the spring can automatically reset and extend, thereby enabling the receiving rod 111 and the extending rod 112 to be inserted into the limiting hole 106, thereby fixing the two refractory brick bodies 100. The plug-in block 108 and the triangular block 109 are smaller than the size of the limiting groove 105, so that concrete can be squeezed out, and the opening of the plug-in groove 101 is sealed by the vertical flange 107. After the concrete dries, the two refractory brick bodies 100 can be fixed more firmly.

[0036] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
