[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] Figure 1 A schematic view of a structure of a guide pipe joint according to an embodiment of the present application, Figure 2 A schematic view of a structure of a guide pipe joint and an exhaust tail pipe ready for installation according to an embodiment of the present application, Figure 3 A schematic view of a structure of a guide pipe joint installed at the end of an exhaust tail pipe according to an embodiment of the present application, please refer to Figures 1 to 3 In an embodiment of the present application, a guide pipe joint 10 is provided, which comprises a pipe body 100 and a fixing assembly 200. The pipe body 100 comprises a joint segment 110, and the two ends of the joint segment 110 are respectively a first end portion 111 and a second end portion 112 in the axial direction of the pipe body 100. The first end portion 111 is used to extend into the exhaust tail pipe 20, and the diameter of the joint segment 110 gradually increases from the first end portion 111 to the second end portion 112. The fixing assembly 200 is fixedly arranged on the outside of the pipe body 100, and is used to fix the guide pipe joint 10 and the exhaust tail pipe 20.
[0024] The guide pipe joint 10 in the present application is usually arranged between the exhaust tail pipe 20 and a guide pipe (not shown in the figure). The guide pipe is usually long, and the end of the exhaust tail pipe 20 is isolated from the external environment through the guide pipe, so that the exhaust noise cannot be directly transmitted to the test environment, thereby the engine exhaust noise can be separated from the test environment, and the noise problem of the engine itself can be more accurately identified and eliminated.
[0025] Referring to Figure 1 The joint segment 110 of the pipe body 100 can be a circular truncated cone. It can be understood that the diameters of the first end portion 111 and the second end portion 112 are set according to the inner diameter range of the industry exhaust tail pipe 20. The diameter of the first end portion 111 can be less than or equal to the minimum diameter of the industry exhaust tail pipe 20, so as to be suitable for the thinnest exhaust tail pipe 20 in the industry. The size of the diameter of the second end portion 112 can be set according to actual needs, and the larger the size of the diameter of the second end portion 112, the richer the caliber of the exhaust tail pipe 20 suitable for the guide pipe joint 10, and the better the sealing performance.
[0026] Continuing to refer to Figure 1 The pipe body 100 further comprises a main body segment 120 connected with the second end portion 112 of the joint segment 110. The end of the main body segment 120 away from the second end portion 112 is connected with the guide pipe. The diameter of the main body segment 120 away from the second end portion 112 can be set according to the diameter of the guide pipe to be connected, so as to ensure that the connection part has good sealing performance.
[0027] It can be understood that the joint segment 110 and the main body segment 120 can be an integrally formed structure or a split structure, which is set according to actual needs. When the joint segment 110 and the main body segment 120 are a split structure, they can be fixedly connected through welding or screwing.
[0028] In some possible embodiments, the fixing assembly 200 comprises a support rod 210 and a clamp 220, one end of the support rod 210 is hinged to the clamp 220, the other end of the support rod 210 is connected to the pipe body 100, and the size of the opening 01 of the clamp 220 is adjustable, so that it can be used to fix exhaust tail pipes 20 of different diameters.
[0029] It can be understood that the specific structure of the clamp 220 and the adjustment method of the size of the opening 01 are not limited in the present application, as long as the function of fixing exhaust tail pipes 20 of different diameters can be achieved.

As Figure 1 and Figure 3 shown, by adjusting the bidirectional adjusting bolt 222, the distance between the two adjacent clamp bodies 221 can be adjusted to adjust the size of the opening 01, so that the clamp 220 can be matched with exhaust tail pipes 20 of different sizes. By connecting the two adjacent clamp bodies 221 with the bidirectional adjusting bolt 222, not only can additional tightening force be applied to ensure the sealing and safety between the exhaust tail pipe 20 and the clamp body 221, but also the clamp 220 can be easily loosened and refastened without disassembling the entire clamp 220.
[0031] Among them, the number of clamp bodies 221 can be two, three or more than three, which is set according to actual needs. As Figure 1 shown, the fixing assembly 200 only comprises two clamp bodies 221, which is simple in structure.
[0032] Continuing to refer to Figures 1 to 3 , the clamp body 221 comprises an arc segment 221a, which is used to abut against the outer wall of the exhaust tail pipe 20 to clamp the exhaust tail pipe 20.

[0034] In some possible embodiments, the clamping body 221 further comprises at least two protrusions 221c arranged on the surface of the connecting segment 221b away from the exhaust tail pipe 20, and the protrusions 221c are hinged to the support rod 210. As shown in Figure 1 The end of the support rod 210 close to the clamp 220 is provided with a groove, the protrusion 221c is inserted into the groove, and a connecting rod penetrates through the protrusion 221c, and the two ends of the connecting rod are connected with the two opposite sidewalls of the groove, respectively. The protrusion 221c can rotate around the connecting rod, so that the position of the clamping body 221 can be flexibly adjusted.

[0036] It can be understood that the support rod 210 is hinged to the support plate 300, so that the included angle between the support rod 210 and the support plate 300 can be flexibly adjusted, thereby the guide pipe joint 10 can be adapted to the exhaust tail pipe 20 with different diameters, and interference between the support rod 210 and the exhaust tail pipe 20 can be avoided, and meanwhile the clamp 220 can clamp the exhaust tail pipe 20.

The support plate 300 and the pipe body 100 are integrally formed, which helps to improve the overall structural strength.
[0040] Continuously referring to Figures 1 to 3 , the use process of the guide pipe joint 10 is specifically described as follows:
[0041] 1) The exhaust tail pipe 20 is inserted through the opening 01 of the clamp 220, the guide pipe joint 10 is moved along the installation direction D to approach the exhaust tail pipe 20, and when the first end 111 of the joint segment 110 is inserted into the exhaust tail pipe 20 and abuts against the exhaust tail pipe 20, the guide pipe joint 10 stops moving;
[0042] 2) Adjust the angle of the support rod 210 and the size of the opening 01 of the clamp 220, so that the arc segment 221a of the clamp body 221 and the exhaust tail pipe 20 abut, and tighten the two-way adjusting bolt 222, so that the exhaust tail pipe 20 and the guide pipe joint 10 are fixed.
