[0021] To detect automobile exhaust, it is necessary to use a portable exhaust extension tube to connect to the automobile exhaust pipe outlet to detect the exhaust gas. However, the existing automobile exhaust pipes have different diameters and specifications. When the exhaust extension tube for detection is connected to the automobile exhaust pipe, it is easy to have a loose connection, resulting in inaccurate automobile exhaust detection results. Therefore, a vehicle exhaust extension device that can tightly connect to the automobile exhaust pipe is needed.
[0022] like Figure 1-2 As shown, the device includes a detection tube 1 for exhaust gas transportation, one end of the detection tube 1 is fixedly installed with a docking port 2 for docking with the automobile exhaust pipe, the outside of the docking port 2 is provided with a fixing sleeve 3 for fixing the docking port 2 to the exhaust pipe mouth of the automobile, the inside of the fixing sleeve 3 is provided with a pushing ring 4 sleeved on the outer surface of the docking port 2, the outside of the pushing ring 4 is provided with a moving group 5 for moving the pushing ring 4 closer, and the inside of the fixing sleeve 3 is provided with a fixing group 6 for fixing the fixing sleeve 3 on the automobile exhaust pipe.
[0023] The fixing sleeve 3 is fixed to the outside of the automobile exhaust pipe opening through the fixing group 6, and then the pushing ring 4 is pushed through the moving group 5, so that the pushing ring 4 pushes the docking port 2 inside the fixing sleeve 3 to tightly dock on the exhaust pipe opening, and the exhaust pipe and the extended detection tube 1 are tightly connected to perform automobile exhaust detection.
[0024] First, the specific structure of the moving group 5 is disclosed. The moving group 5 includes a connecting plate 501 fixedly installed on the outer surface of the push ring 4. A stud 502 for pushing the push ring 4 to move is rotatably installed on one side of the connecting plate 501. The outer surface of the stud 502 is threadedly connected with a positioning plate 503.
[0025] A slide groove 301 is provided on the outer surface of the fixing sleeve 3 , and the top of the connecting plate 501 passes through the slide groove 301 and extends to the outside of the fixing sleeve 3 . The positioning plate 503 is fixedly mounted on the outer surface of the fixing sleeve 3 for fixing.
[0026] When testing automobile exhaust, the fixed sleeve 3 is fixed to the outside of the automobile exhaust, and the stud 502 inside the positioning plate 503 is rotated so that the stud 502 pushes the connecting plate 501 to move forward in the slide groove 301, so that the pushing ring 4 installed at the bottom of the connecting plate 501 pushes the internal sleeve-connected docking port 2 to move forward inside the fixed sleeve 3, so that the funnel-shaped docking port 2 is tightly docked with the automobile exhaust emission pipe mouth, so as to achieve the effect of tightly docking the automobile exhaust pipe mouth and the extended detection tube 1, avoiding automobile exhaust leakage and causing inaccurate detection results.
[0027] The improvement of this embodiment is that: through the structure of the connecting plate 501 and the stud 502, the effect of pushing the docking port 2 to dock tightly is achieved, which solves the problem of loose docking between the extended detection tube 1 and the automobile exhaust pipe port in the prior art.
[0028] Due to the prior art of how to fix the fixing sleeve 3 on the automobile exhaust pipe, Figure 2-Figure 3 A second embodiment of the present utility model is shown.
[0029] The specific structure of the fixing group 6 is disclosed again. The fixing group 6 includes an arc-shaped pressing plate 601 for squeezing the automobile exhaust pipe. A threaded column 602 is rotatably installed on the top of the arc-shaped pressing plate 601. A rotating handle 603 for rotating the threaded column 602 is fixedly installed on the top of the threaded column 602.
[0030] The arc-shaped pressing plate 601 is disposed inside the fixing sleeve 3 , and the threaded column 602 penetrates the fixing sleeve 3 and extends to the outer surface of the rotating handle 603 .
[0031] The threaded column 602 is threadedly connected to the inside of the fixing sleeve 3. The top of the threaded column 602 passes through the fixing sleeve 3 and is connected to the rotating handle 603. The bottom is rotatably installed on the top of the arc-shaped pressure plate 601. When installing the fixing sleeve 3, the fixing sleeve 3 is sleeved on the exhaust pipe opening of the automobile. The rotating handle 603 is rotated to move the threaded column 602 downward, so that the arc-shaped pressure plate 601 is squeezed on the outer surface of the exhaust pipe opening of the automobile. Two arc-shaped pressure plates 601 are provided, and the fixing sleeve 3 is fixed on the exhaust pipe opening of the automobile from both sides of the fixing sleeve 3. The arc-shaped pressure plate 601 has a large contact area with the outer surface of the automobile exhaust pipe, and will not cause damage to the outside of the pipe, so it is convenient to connect the docking port 2 to the exhaust pipe opening of the automobile.
[0032] The improvement of this embodiment is that the fixing sleeve 3 is fixed on the automobile exhaust pipe through the arc-shaped pressing plate 601 structure.
[0033] In summary, the working principle of this solution is as follows:
[0034] When testing automobile exhaust, the fixing sleeve 3 is fixed to the outside of the automobile exhaust, and the stud 502 inside the positioning plate 503 is rotated, so that the stud 502 pushes the connecting plate 501 to move forward in the slide groove 301, so that the pushing ring 4 installed at the bottom of the connecting plate 501 pushes the internal sleeve-connected docking port 2 to move forward inside the fixing sleeve 3, so that the funnel-shaped docking port 2 is closely docked with the automobile exhaust emission pipe port, so as to achieve the effect of closely docking the automobile exhaust pipe port and the extended detection tube 1, thereby avoiding automobile exhaust leakage and causing inaccurate detection results;
[0035] When installing the fixing sleeve 3, the fixing sleeve 3 is sleeved on the automobile exhaust pipe opening, and the rotating handle 603 is rotated to move the threaded column 602 downward, so that the arc-shaped pressure plate 601 is squeezed on the outer surface of the automobile exhaust pipe opening. Two arc-shaped pressure plates 601 are provided, and the fixing sleeve 3 is fixed on the automobile exhaust pipe opening from both sides of the fixing sleeve 3. The arc-shaped pressure plate 601 has a large contact area with the outer surface of the automobile exhaust pipe, and will not cause damage to the outside of the pipe, so it is convenient to connect the docking port 2 to the automobile exhaust pipe opening.
