DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] according to Figure 1-Figure 5As shown, it includes an exhaust pipe 1, one end of the exhaust pipe 1 is provided with four groups of mounting holes 11, and the interior of the mounting holes 11 is installed with mounting rings 21 through mounting bolts 22, the inner wall of the mounting ring 21 is installed with a collecting pipe 2, and a collecting port 23 is provided on the side surface of the collecting pipe 2 near the top side, one end of the collecting pipe 2 extends into the interior of the exhaust pipe 1, threaded holes 24 are provided on both sides of the collecting port 23, and one ends of two groups of fixing bolts 32 respectively extend into the interior of the corresponding threaded holes 24 and are movably screwed thereto.

[0022] A connecting pipe 3 is movably provided inside the collecting port 23, and fixing plates 31 are installed on both sides of the connecting pipe 3. Fixing bolts 32 are movably screwed inside the two sets of fixing plates 31. A through-hole 33 is opened on the other side of the connecting pipe 3, and a collecting cover 34 is connected to the top of the connecting pipe 3. The collecting cover 34 is connected to the interior of the collecting pipe 2 through the connecting pipe 3 and the collecting port 23. A mounting plate 35 is installed at the bottom of one side of the collecting cover 34, and an electric push rod 36 is installed on the inner wall of one side of the mounting plate 35. The two sets of fixing plates 31 and the mounting plate 35 are both L-shaped. A sealing plate 37 is installed at one end of the electric push rod 36. One end of the sealing plate 37 passes through the inner wall of one side of the connecting pipe 3 through the through-hole 33 and extends into the interior of the connecting pipe 3. The width of the sealing plate 37 is adapted to the distance between the front and rear inner walls of the connecting pipe 3.

[0023] When in use, the user can extend one end of the collecting pipe 2 into the interior of the exhaust pipe 1, so that one side surface of the mounting ring 21 can be fitted with the one end surface of the exhaust pipe 1. At this time, four sets of mounting bolts 22 can be screwed and fixed to the inside of the corresponding mounting holes 11, so that the mounting ring 21 can be screwed and installed with one end of the exhaust pipe 1. When the exhaust pipe 1 starts to discharge exhaust gas, the exhaust gas will flow into the interior of the collecting pipe 2. Subsequently, due to the high temperature of the exhaust, the exhaust gas can rise and move by itself, so that the exhaust gas inside the collecting pipe 2 can flow into the interior of the collecting cover 34 through the collecting port 23 and the connecting pipe 3, so that the exhaust gas can be collected accordingly inside the collecting cover 34. When the collecting cover 3 After the exhaust gas inside is collected, the user can start the electric push rod 36 to move the sealing plate 37 toward the inside of the connecting pipe 3, so that the inside of the connecting pipe 3 can be sealed by the sealing plate 37, thereby preventing the exhaust gas from flowing back. After that, the user can rotate the two sets of fixing bolts 32 accordingly, so that one end of the two sets of fixing bolts 32 can be rotated out from the inside of the corresponding threaded holes 24 respectively. At this point, the disassembly between the collecting cover 34 and the connecting pipe 3 and the collecting port 23 can be completed. After that, the collecting pipe 2 and the exhaust pipe 1 can be disassembled accordingly. Finally, the collecting cover 34 with the exhaust gas inside can be transferred to the corresponding detection device and tested accordingly.
