DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings:
[0023] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0024] The multifunctional automobile exhaust collection tool comprises: a combined pipe assembly 100, a blind plate 200, an exhaust bellows assembly 300, a flange reducer 400, and a silicone tube 500, and is characterized in that: an exhaust pipe 101 is provided on one side of the combined pipe assembly 100, and a plurality of intake pipes 102 are provided on the other side, and a blind plate 200 or an exhaust bellows assembly 300 is installed at the edge of the intake pipe 102; one end of the flange reducer 400 is connected to the exhaust bellows assembly 300, and the other end is connected to the silicone tube 500; wherein the blind plate 200, the exhaust bellows assembly 300 and the intake pipe 102 have a variety of combined structures, and the number of the exhaust bellows assemblies 300 is the same as the number of the intake pipes 102 used. In this way, after the exhaust bellows assembly 300, the flange reducer 400, and the silicone tube 500 are connected in series, the exhaust bellows assembly 300 is connected to the intake pipe 102 of the combined pipe assembly 100. The other intake pipes 102 that are not connected to the exhaust bellows assembly 300 are sealed at the edges of the intake pipes 102 using the blind plate 200, so that the exhaust gas entering from the exhaust bellows assembly 300 will not leak out from other intake pipes 102, ensuring that the exhaust gas can enter the detection device in sufficient quantity through the exhaust pipe, thereby improving the accuracy of the exhaust test.
[0025] Optionally, the combined pipe assembly 100, the blind plate 200, the exhaust bellows assembly 300, and the flange reducer 400 are made of stainless steel, including but not limited to iron and high-temperature resistant plastic materials.
[0026] Optionally, the silicone tube 500 is made of high temperature resistant silicone and has a certain tensile elasticity. Thus, through its tensile elasticity, it can be sleeved on the outer wall of the tail pipe of different specifications and shapes to ensure the sealing of the connection between the silicone tube 500 and the tail pipe.
[0027] Preferably, the air intake pipes 102 are arranged from one end to the other end, namely the first air intake pipe 103, the second air intake pipe 104, the third air intake pipe 105, and the fourth air intake pipe 106. In this way, the multiple exhaust pipes can be applied to the detection of different numbers of tail pipes, thereby improving the adaptability of the device.
[0028] Preferably, at least one of the first air intake pipe 103, the second air intake pipe 104, the third air intake pipe 105, and the fourth air intake pipe 106 is installed with an exhaust bellows assembly 300; the other three can be installed with a blind plate 200 or an exhaust bellows assembly 300 at their edges. In this way, the number and position of the air intake pipes 102 to be connected can be selected according to actual needs, so that multiple combinations can be formed between the exhaust pipes, thereby improving the adaptability of the device. For example, if the vehicle to be tested has only one tail pipe, it is only connected to the tail pipe of the vehicle to be tested through the first air intake pipe 103, and the other air intake pipes 102 are closed with a blind plate 200. If the vehicle to be tested has two tail pipes, and the two tail pipes are on the same side, one of the first air intake pipe 103, the second air intake pipe 104, the third air intake pipe 105, or the fourth air intake pipe 106 is connected to the tail pipe, and the other unconnected air intake pipes 102 are closed with a blind plate 200. If the vehicle to be tested has three or more tail pipes, different numbers and positions of intake pipes 102 are selected to be connected to the tail pipes according to actual needs, and so on.
[0029] Preferably, a gasket 110 is embedded between the intake pipe 102 and the blind plate 200 or the exhaust bellows assembly 300, and a quick-release clamp 120 is installed at the connection between the intake pipe 102 and the exhaust bellows assembly 300. In this way, the intake pipe 102 and the blind plate 200 or the exhaust bellows assembly 300 can be quickly assembled or disassembled through the quick-release clamp 120, which effectively improves the working efficiency of the detection. In addition, the gasket 110 arranged between the intake pipe 102 and the blind plate 200 or the exhaust bellows assembly 300 can improve the sealing of the connection between the intake pipe 102 and the blind plate 200 or the exhaust bellows, so that the gas is not easily leaked, so as to ensure the accuracy of the detection result.
[0030] Optionally, the gasket 110 is made of copper. In this way, the gasket 110 expands after being heated, further filling the sealing of the connection between the intake pipe 102 and the blind plate 200 or the exhaust bellows assembly 300, so that gas is not easily leaked when passing through, thereby ensuring the accuracy of the detection structure.
[0031] Preferably, a gasket 110 is embedded between the exhaust bellows assembly 300 and the flange reducer 400, and a quick-release clamp 120 is installed at the connection between the two. In this way, the function and effect are the same as the above, and no further description is given.
[0032] Preferably, the outer diameter of the end of the flange reducer 400 away from the exhaust bellows assembly 300 is larger than the inner diameter of the silicone tube 500, but smaller than the outer diameter of the silicone tube 500; and the flange reducer 400 is embedded in the silicone tube 500. In this way, the silicone tube 500 has a certain tensile elasticity, and when the flange reducer 400 is connected to the silicone tube 500, the silicone tube 500 can be tightly wrapped on the outer wall of the flange reducer 400, thereby effectively improving the sealing of the connection between the two.
[0033] Preferably, a flange expansion pipe 600 is further included, one end of which is connected to the exhaust pipe, and the other end is connected to the exhaust bellows assembly 300. In this way, in special cases, the number of intake pipes 102 provided on the combined pipe assembly 100 may be insufficient. At this time, it is necessary to increase the number of intake pipes 102 by installing flange expansion pipes 600 on the intake pipes 102 to ensure that the detection work can be carried out smoothly in special cases.
[0034] Preferably, at least two branch pipes 610 are provided at one end of the flange extension pipe 600 away from the air inlet pipe 102 , so as to increase the number of connections with the exhaust bellows assembly 300 .
[0035] Optionally, a single flange expansion pipe 600 has at least two branch pipes 610 and one connecting pipe 611 , and the connecting pipe 611 is connected to the intake pipe 102 , and the branch pipe 610 is connected to the exhaust bellows assembly 300 .
[0036] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
