The integrated fireproof and heat-insulating assembled smoke and exhaust air duct includes a galvanized steel plate air duct, an angle steel flange, rock wool and a fireproof board. The structure of the integrated fireproof and heat-insulating assembled smoke and exhaust air duct is simple and scientific, and it is easy to assemble; a lot of labor costs can be saved during the assembly process, and there is no need for multiple high-altitude installation operations, and only one high-altitude installation is required to complete it; the factory assembly line is operated and produced, and the production efficiency is greatly improved; the factory integrated assembly ensures the overall air duct quality and aesthetics.

[0004] In the above-mentioned prior art, multiple smoke exhaust ducts are fixed with bolts so that multiple smoke exhaust ducts are spliced ​​into a flue for smoke exhaust. However, when smoke is discharged outward through the smoke exhaust duct, the temperature inside the smoke exhaust duct will increase. When the temperature inside the smoke exhaust duct is too high, the bolts will expand due to the heat. Long-term thermal expansion and contraction will cause the bolts to loosen, thereby making it impossible to fix the connection between the smoke exhaust pipes, causing smoke leakage at the connection of the smoke exhaust pipes.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-5 As shown, the integrated fireproof and heat-insulated assembled smoke-proof and exhaust air duct includes:

[0027] A tube body 1, the side wall of which is provided with locking holes 4 in a linear array;

[0028] Insert blocks 2 are arranged in a linear array on the side wall of the tube body 1, and the insert blocks 2 and the lock holes 4 are arranged on the same axis;

[0029] Lock buckles 5 arranged in a circular array on the side wall of the insert block 2 and slidingly fitted therewith;

[0030] The fastening assembly at least includes a support rod 6 which is arranged in the insert block 2 and is driven to abut against the bottom end of the lock buckle 5.

[0031] Specifically, the two tube bodies 1 are spliced ​​with each other by inserting the plug block 2 installed on the side wall of the tube body 1 into the locking hole 4 starting from the side wall of the other tube body 1, and the support rod 6 installed in the plug block 2 is driven to deform and expand outward, so that the support rod 6 pushes the locking buckle 5 installed in the plug block 2 to slide into the locking hole 4, and the locking buckle 5 slides into the locking hole 4, so that the plug block 2 is fixed in the locking hole 4 by the locking buckle 5. When the plug block 2 is fixed in the locking hole 4, the connection between the two spliced ​​tube bodies 1 is fixed, which not only makes the two tube bodies 1 quickly spliced, but also improves the fixing effect between the two tube bodies 1, and avoids the loosening of the connection between the two tube bodies 1 when the temperature is too high.

[0032] In the above embodiment, a worker aligns the plug block 2 installed on the front end of the tube body 1 with the locking hole 4 at the rear end of the other tube body 1, and at the same time drives the two tube bodies 1 to be plugged into each other so that the plug block 2 is inserted into the locking hole 4. The plug block 2 and the locking hole 4 cooperate with each other to restrict the two tube bodies 1, thereby avoiding the connection between the two tube bodies 1 from being offset, thereby improving the installation efficiency. After the plug block 2 is inserted into the locking hole 4, the support rod 6 is driven to deform and bend, so that the support rod 6 pushes the lock buckle 5 to slide into the locking hole 4. When the lock buckle 5 enters the locking hole 4, the lock buckle 5 fixes the plug block 2 in the locking hole 4, so that the plug block 2 cannot be separated from the locking hole 4, thereby making the two tube bodies 1 spliced ​​together to form a flue, which not only avoids the inability to fix the connection between the tube bodies 1 when the bolts are loose, but also improves the splicing efficiency between the smoke exhaust pipes.

[0033] As an embodiment further provided by the present invention, a slide groove 8 is provided in the insert block 2 , a slider 7 is movably installed in the slide groove 8 , and one end of the slider 7 is fixedly connected to a support rod 6 .

[0034] Furthermore, an elastic member 11 is fixedly installed in the slide groove 8 , and one end of the elastic member 11 is fixedly connected to the slide block 7 .

[0035] Specifically, the elastic member 11 provides thrust to the slider 7, so that the slider 7 slides along the slide groove 8 and squeezes the support rod 6, causing the support rod 6 to deform. When the support rod 6 deforms and expands outward, the support rod 6 pushes the lock buckle 5 to slide into the lock hole 4, so that the lock buckle 5 is fixed in the lock hole 4.

[0036] As another embodiment further provided by the present invention, the side wall of the tube body 1 begins to have symmetrically arranged trapezoidal grooves 9 .

[0037] Furthermore, a through hole 12 in a circular array is opened in the tube body 1, one end of the through hole 12 is connected to the trapezoidal groove 9, and the other end of the through hole 12 is connected to the slide groove 8. A push rod 10 is movably installed in the through hole 12, and one end of the push rod 10 extends into the slide groove 8 and abuts against the slider 7.

[0038] Furthermore, a trapezoidal push block 3 is symmetrically arranged on the side wall of the tube body 1 .

[0039] Specifically, workers splice the two tube bodies 1 together so that the trapezoidal push block 3 fixedly installed on the side wall of the tube body 1 is inserted into the trapezoidal groove 9. When the trapezoidal push block 3 moves into the trapezoidal groove 9, the side wall of the trapezoidal push block 3 pushes the push rod 10, so that the push rod 10 slides along the through hole 12 into the slide groove 8. When one end of the push rod 10 extends into the slide groove 8, the push rod 10 abuts against the bottom end of the slider 7, so that the slider 7 is clamped, thereby improving the support effect provided by the slider 7 to the support rod 6, and preventing the support rod 6 from loosening when the temperature is too high.

[0040] Working principle: by inserting the plug block 2 installed on the tube body 1 into the locking hole 4 opened on the other tube body 1, the two tube bodies 1 are spliced ​​together, and the elastic member 11 installed in the plug block 2 pushes the slider 7 to slide along the slide groove 8 and squeezes the support rod 6, so that the support rod 6 is deformed and expanded and provides thrust to the lock buckle 5, and one end of the lock buckle 5 extends into the locking hole 4, so that the lock buckle 5 fixes the plug block 2 in the locking hole 4, thereby fixing the mutually spliced ​​tube bodies 1. When the two tube bodies 1 are spliced ​​together, the trapezoidal push block 3 is inserted into the trapezoidal groove 9. In the process of the trapezoidal push block 3 moving into the trapezoidal groove 9, the trapezoidal push block 3 pushes the push rod 10, so that the push rod 10 slides along the through hole 12 into the slide groove 8, so that one end of the push rod 10 is fixed on the slider 7, and one end of the push rod 10 is fixed on the slider 7, so that the slider 7 is clamped by the push rod 10, so as to prevent the slider 7 from loosening and affecting the supporting effect of the support block 6.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
