[0035] like Figure 1-5As shown, this utility model embodiment proposes a connecting structure for a mechanical flue, installed between adjacent flue bodies 10, including: a first connecting frame 20, installed at the end of one of the flue bodies 10, and having multiple slots 21 on its inner side; and a second connecting frame 30, installed at the end of the other flue body 10, and having multiple locking blocks 31 on its outer side; wherein, when the two flue bodies 10 are connected, the first connecting frame 20 is fitted onto the second connecting frame 30, and the multiple locking blocks 31 are correspondingly locked onto the multiple locking blocks 31. Inside the slot 21; a limiting component, the first connecting frame 20 has an installation cavity 22 that extends through multiple slots 21, the limiting component includes a limiting block 40 that is slidably disposed in the installation cavity 22 and corresponds to the multiple slots 21 and an adjusting member 50 that is rotatably disposed in the installation cavity 22, the adjusting member 50 is used to connect with the multiple limiting blocks 40 so that the multiple limiting blocks 40 protrude from the corresponding slots 21 or are housed in the installation cavity 22, so that the limiting blocks 40 abut against the card block 31 or separate from it.

[0036] In this embodiment of the utility model, before installation, the first connecting frame 20 is first installed on the end of a flue body 10, and then the second connecting frame 30 is installed on the end of another flue body 10, so that the first connecting frame 20 and the second connecting frame 30 form an integral part with their respective flue bodies 10.

[0037] When connecting two adjacent flue bodies 10, first align one end of the flue body 10 with the one with the second connecting frame 30 and the one with the first connecting frame 20. If the flue body 10 with the second connecting frame 30 is already installed, then place the flue body 10 with the first connecting frame 20 above the end of the flue body 10 with the second connecting frame 30. Then, gradually lower it so that the first connecting frame 20 fits onto the second connecting frame 30, so that multiple locking blocks 31 are aligned with and inserted into the locking slots 21, thereby achieving the positioning and alignment of the two flue bodies 10.

[0038] After the docking is completed, the adjusting component 50 drives multiple limiting blocks 40 to move within the mounting cavity 22, so that the multiple limiting blocks 40 protrude to the corresponding positions of multiple slots 21 and abut against the surfaces of multiple slot blocks 31, thereby achieving the limiting and fixing of multiple slot blocks 31, so that the two flue bodies 10 remain stable after connection, thereby improving the assembly strength at the connection of the two flue bodies 10.

[0039] Specifically, such as Figure 2-5As shown in this embodiment of the present invention, the adjusting member 50 includes an adjusting screw 51 rotatably disposed in the mounting cavity 22 and an adjusting nut 52 disposed at the end of the adjusting screw 51. The adjusting screw 51 is threadedly connected to the limiting block 40. The adjusting nut 52 and the adjusting screw 51 are fixedly connected, so that rotating the adjusting nut 52 can drive the adjusting screw 51 to rotate, thereby causing the limiting block 40 to slide along the axial direction of the mounting cavity 22, so that the limiting block 40 protrudes from the corresponding slot 21 or is housed within the mounting cavity 22, thereby completing the limiting or releasing of the locking block 31. Simultaneously, for ease of operation, a limiting device is provided on one side of the slot 21 within the mounting cavity 22. Plate 60; When the rotating adjusting screw 51 drives the limiting block 40 to slide along the mounting cavity 22, the limiting block 40 will abut against the limiting plate 60. At this time, the limiting block 40 is completely protruding from the slot 21, and the personnel cannot rotate the adjusting screw 51, thus making it convenient for personnel to judge whether the limiting block 40 is installed in place; In addition, the width of the limiting block 40 is greater than the width of the slot 21, so that the limiting block 40 can completely block the slot 21, thereby improving the limiting effect on the slot 31; and a slider 41 is provided on one side of the limiting block 40, and a sliding groove is provided in the mounting cavity 22 to slide smoothly along the mounting cavity 22 under the drive of the adjusting screw 51.

[0040] Specifically, such as Figure 1-2 As shown in this embodiment of the invention, the side of the first connecting frame 20 is recessed inward to form a groove, and the adjusting nut 52 is embedded in the groove. The groove allows the adjusting nut 52 to be placed inside the first connecting frame 20, making its structure more compact. Furthermore, the adjusting nut 52 facilitates the use of tools to adjust the adjusting screw 51. Simultaneously, a clearance opening 11 is provided on the flue body 10 where the first connecting frame 20 is installed, corresponding to the position of the adjusting nut 52, to facilitate the adjustment of the adjusting nut 52. In this embodiment, the adjusting nut 52 is a hexagonal nut.

[0041] It should be noted that in this embodiment, there are two limiting blocks 40, and the two ends of the adjusting screw 51 are respectively provided with threaded portions, and the two threaded portions rotate in opposite directions. The two threaded portions are threadedly connected to the two limiting blocks 40 respectively. That is, by rotating the adjusting screw 51, the two limiting blocks 40 can be driven to slide synchronously in opposite directions, thereby simultaneously protruding from the corresponding slots 21 to symmetrically limit and lock the locking blocks 31, improving their stability and reliability. Of course, in another embodiment, the number of limiting blocks 40 can be set to three or four, etc. In this case, the adjusting screw 51 has only one threaded portion, and multiple limiting blocks 40 are threadedly connected to this threaded portion; then by rotating the adjusting screw 51, multiple limiting blocks 40 can be simultaneously driven to slide along the mounting cavity 22, so that they protrude from the corresponding slots 21 to limit and lock multiple locking blocks 31.

[0042] It should also be noted that in this embodiment, the plurality of slots 21 are respectively opened on the left and right sides of the first connecting frame 20. Correspondingly, the mounting cavity 22 and the limiting component are also set to two, which correspond to the plurality of slots 21 on the left and right sides respectively. By setting the limiting components on both the left and right sides, the plurality of locking blocks 31 on both sides can be limited and locked, so that the two flue bodies 10 obtain symmetrical and stable constraint force after connection, further improving the overall connection's firmness and reliability.

[0043] Based on the above solutions, such as Figure 1 and Figure 5 As shown in this embodiment of the present invention, a sealing groove 70 is provided on the end face of the first connecting frame 20 and / or the end face of the second connecting frame 30; the sealing groove 70 can accommodate a sealing strip or a sealing ring to ensure the sealing performance of the contact surface of the end face of the first connecting frame 20 and the end face of the second connecting frame 30 after assembly; at the same time, after the flue body 10 is connected in pairs, cement slurry can be applied to its connection point to further enhance the sealing effect and avoid the phenomenon of smoke leakage.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
