The clamp 1 38 and the clamp 2 30 form a whole clamp through the bolt 39, and the interface of the smoke exhaust pipe is closed and connected.

[0035] Reference Figure 1-Figure 3 The surface of the embedded block 32 is fixedly connected to the outer wall of the pipeline plate 2. The embedded block 32 is set in a dovetail shape and matches the dovetail-shaped embedded groove 31 to improve the anti-pulling force of the assembly of the pipeline plate 1 and the pipeline plate 2. The outer wall of the embedded block 32 is adapted to the inner wall of the embedded groove 31, the outer wall of the insertion rod 34 is adapted to the inner wall of the through groove 33, the inner wall of the through groove 33 is threadedly connected to the threaded groove 35, the outer wall of the positioning column 37 is adapted to the inner wall of the positioning hole 36, and the cooperation of the positioning column 37 and the positioning hole 36 enables the clamp 1 38 to obtain the positioning function before being connected to the clamp 2 30, avoiding the need to repeatedly align the screw holes of the clamp 1 38 and the clamp 2 30, so as to facilitate the sealing and fixing of the interfaces of the two sets of smoke exhaust pipes.

[0036] Reference Figure 4-Figure 5A sealing structure 4 is provided on the surface of the pipeline plate 2, and the sealing structure 4 includes a silicone soft strip 41. The silicone soft strip 41 is provided in an L shape and the material can be bent. A double-sided adhesive strip 42 is provided on the outer side of the silicone soft strip 41. A sealing strip 43 is fixedly connected to the inner surface of the clamp 38. A groove 44 is provided on the surface of the sealing strip 43. The outer wall of the silicone soft strip 41 is fixedly connected to the inner surface of the pipeline plate 2.

When the length of the smoke exhaust pipe needs to be increased, insert the insertion rod 34 into the through groove 33 in turn. After the insertion rod 34 enters the through groove 33 for a distance, rotate the insertion rod 34 so that the insertion rod 34 is fixed on the assembled smoke exhaust pipe, and then insert another set of matching smoke exhaust pipes. Insert the rod 34, repeat the above steps to increase the installation length of the smoke exhaust pipe according to the required length, and then insert the positioning column 37 into the positioning hole 36 in turn, so that the clamp 1 38 and the clamp 2 30 cover the two sides of the smoke exhaust pipe, and then fix the clamp 1 38 and the clamp 2 30 with the bolt 39, and the two gradually approach each other. At this time, the sealing strip 43 will be tightly attached to the interface of the two groups of smoke exhaust pipes, and the groove 44 makes the sealing strip 43 squeezed by force to produce relative deformation to ensure the fit at the interface, so that the overall smoke exhaust pipe can be quickly assembled. At the same time, the area of ​​the placement area can be reduced after disassembly, which is convenient for transportation.
