For example, technical personnel in this field can also install the pipeline machine in a horizontal direction, etc. Such adjustments and changes to the specific installation direction of the pipeline machine do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0045] Next, the technical solution of the present invention will be further explained by taking the installation of the pipeline machine in the vertical direction as an example.

[0047] For example, Figures 2 to 6As shown, taking the duct machine as an example, the exhaust port 33 of the fan 3 of the utility model is rectangular, and the left and right sides of the exhaust port 33 are provided with first mounting flanges 31 arranged in the horizontal direction and extending in the front-to-back direction, and the mounting plate 4 is provided with vents 43 arranged corresponding to the exhaust port 33, and the left and right sides of the vents 43 are provided with first folding plates 41 extending in the front-to-back direction, and the plane where the first folding plate 41 is located is located below the plane where the mounting plate 4 is located, and there is a first plug-in gap between the plane where the first folding plate 41 is located and the plane where the mounting plate 4 is located, and the first plug-in gap can just accommodate the first The mounting flange 31 is inserted, and the front end of the first folding plate 41 is an insertion port. A portion of the first mounting flange 31 can be inserted into the first plug-in gap from front to back, so that the fan 3 is plugged into the mounting plate 4 to align the exhaust port 33 and the vent 43. The first mounting flange 31 and the first folding plate 41 are respectively provided with matching first guide structures and second guide structures. When the fan 3 is plugged in and installed, the first mounting flange 31 can be smoothly inserted into the first plug-in gap along the first guide structure and the second guide structure, thereby avoiding installation problems such as jamming and improper installation, and improving the installation efficiency of the fan 3.

[0048] It should be noted that the present invention does not limit the structural form of the first guide structure and the second guide structure. For example, a person skilled in the art may configure the first guide structure and the second guide structure as matching guide ribs and guide grooves, or as matching guide columns and guide grooves, etc. Such adjustments and changes to the specific structural forms of the first guide structure and the second guide structure do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0049] Preferably, if Figures 3 to 6 As shown, one of the first guide structure and the second guide structure of the utility model is a guide rib 311 extending along the first direction, and the other of the first guide structure and the second guide structure is a guide groove 411 extending along the first direction, and the guide rib 311 is adapted to the guide groove 411.

[0050] For example, Figures 3 to 6 As shown, the first mounting flange 31 is provided with a guide rib 311 extending along the front-to-back direction and arranged downward, and the first folding plate 41 is provided with a guide groove 411 extending along the front-to-back direction and arranged downward. When the fan 3 is plugged in and installed, the guide rib 311 can slide along the guide groove 411, so that the first mounting flange 31 can be smoothly inserted into the first plug-in gap, thereby improving the installation efficiency of the fan 3.

Such adjustments and changes to the specific setting positions of the guide ribs 311 and the guide grooves 411 do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0052] Preferably, if Figures 3 to 6 As shown, a first guide edge 412 is provided at one end of the first folding plate 41 of the utility model close to the insertion opening of the first insertion gap, and the first guide edge 412 is inclined in a direction away from the mounting plate 4 .

[0053] For example, Figures 3 to 6 As shown, the front end of the first folding plate 41 is provided with a first guide edge 412 inclined downward. By providing the first guide edge 412 at the front end of the first folding plate 41, the first mounting flange 31 can be easily inserted from the insertion port into the first plug-in gap, thereby improving the installation efficiency of the fan 3.

[0054] Preferably, if Figures 2 to 5 As shown, the utility model provides a second folding plate 42 on one side of the insertion port of the vent 43 away from the first plug-in gap, a second plug-in gap is provided between the plane where the second folding plate 42 is located and the plane where the mounting plate 4 is located, and a corresponding second mounting flange 32 is provided on the side of the exhaust port 33 opposite to the second folding plate 42, the second mounting flange 32 is arranged along a second direction, the second direction is perpendicular to the first direction, and at least a portion of the second mounting flange 32 is inserted into the second plug-in gap.

[0055] For example, Figures 2 to 5 As shown, a second mounting flange 32 which is arranged in a horizontal direction and extends in a left-right direction is provided on the rear side of the exhaust port 33, and the second mounting flange 32 and the first mounting flange 31 are located in the same horizontal plane, and a second folding plate 42 is provided on the rear side of the vent 43, and the second folding plate 42 and the first folding plate 41 are located in the same horizontal plane, that is, the plane where the second folding plate 42 is located is located below the plane where the mounting plate 4 is located, and there is a second plug-in gap between the plane where the second folding plate 42 is located and the plane where the mounting plate 4 is located, that is, the second plug-in gap and the first plug-in gap are the same size, and in the process of the first mounting flange 31 being inserted from front to back into the first plug-in gap, the second mounting flange 32 also moves from front to back with the fan 3 and is inserted into the second plug-in gap, so that the left and right ends and the rear end of the exhaust port 33 are simultaneously against the mounting plate 4, thereby increasing the installation area of ​​the fan 3 and increasing the installation strength.

[0056] It should be noted that the present invention does not limit the size of the first mounting flange 31 inserted into the first plug-in gap and the size of the second mounting flange 32 inserted into the second plug-in gap. For example, a person skilled in the art may insert the entire first mounting flange 31 into the first plug-in gap and the entire second mounting flange 32 into the second plug-in gap, or may partially insert the first mounting flange 31 into the first plug-in gap and partially insert the second mounting flange 32 into the second plug-in gap, and so on. As long as the sizes of the first mounting flange 31 and the second mounting flange 32 and the first folding plate 41 and the second folding plate 42 are adjusted according to actual installation needs, such adjustment and change of the specific size of the first mounting flange 31 inserted into the first plug-in gap and the specific size of the second mounting flange 32 inserted into the second plug-in gap does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0057] In addition, it should be noted that the present invention does not limit the installation positions of the first mounting flange 31 and the second mounting flange 32 and the first folding plate 41 and the second folding plate 42. For example, a person skilled in the art may also set the first mounting flange 31 and the second mounting flange 32 not in the same plane, and correspondingly, set the first folding plate 41 and the second folding plate 42 not in the same plane. As long as the first mounting flange 31 can be inserted into the first plug-in gap along the first folding plate 41, and the second mounting flange 32 can also be inserted into the second plug-in gap, such adjustment and change of the specific installation positions of the first mounting flange 31 and the second mounting flange 32 and the first folding plate 41 and the second folding plate 42 do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0058] Of course, the present invention preferably arranges the first mounting flange 31 and the second mounting flange 32 and the first folding plate 41 and the second folding plate 42 in the same plane to facilitate production and installation.

[0059] Next, the technical solution of the present invention will be further described with the first mounting flange 31 and the second mounting flange 32 and the first folding plate 41 and the second folding plate 42 being arranged on the same plane.

[0060] Preferably, if Figures 2 to 5 As shown, the number of the second folding plates 42 of the utility model is two, and the two second folding plates 42 are spaced apart along the second direction. A clamping plate 44 is formed at a position of the mounting plate 4 corresponding to the gap between the two second folding plates 42, and the gap between the clamping plate 44 and the two second folding plates 42 forms a second plug-in gap.

[0061] For example, Figures 2 to 5As shown, two second folding plates 42 are provided at intervals along the left-right direction on the rear side of the vent 43, and a clamping plate 44 is provided above the gap between the two second folding plates 42. The clamping plate 44 and the mounting plate 4 are located in the same plane and are integrally arranged, that is, the gap between the clamping plate 44 and the two second folding plates 42 is the second plug-in gap.

[0062] It should be noted that the present invention does not limit the size of the card plate 44. For example, a person skilled in the art may set the card plate 44 to be the same size as the gap between the two second folding plates 42, or may set the card plate 44 to be larger than or smaller than the gap between the two second folding plates 42, and so on. As long as the second mounting flange 32 can be fixed between the card plate 44 and the two second folding plates 42, such adjustment and change of the specific size of the card plate 44 does not deviate from the principle and scope of the present invention, and shall be limited within the protection scope of the present invention.

Such an arrangement increases the support area, increases the support strength of the first folding plate 41 and the second folding plate 42, and reduces the probability of deformation of the first folding plate 41 and the second folding plate 42.

[0065] Preferably, if Figures 2 to 5 As shown, the clamping plate 44 of the present invention is provided with a second guide edge 441 at one end close to the insertion port, and the second guide edge 441 is inclined in a direction away from the second folding plate 42 .

[0066] For example, Figures 2 to 5 As shown, the front end of the clamping plate 44 is configured as a second guide edge 441 that is tilted upward. Through such a configuration, the second mounting flange 32 is more easily inserted into the second insertion gap.

[0067] Preferably, if Figure 3 , Figure 5 and Figure 6As shown, the utility model has a first limit plate 34 on the side of the exhaust port 33 opposite to the second mounting flange 32, and the mounting plate 4 has two second limit plates 45 which are spaced apart along the second direction and correspond to the two ends of the first limit plate 34. When the second mounting flange 32 is inserted into the second plug-in gap, the two ends of the first limit plate 34 just abut against the corresponding second limit plates 45.

When the second mounting flange 32 is inserted into the second plug-in gap, the two ends of the first limit plate 34 just abut against the corresponding second limit plates 45.

[0069] It should be noted that the present invention does not limit the connection method between the first limit plate 34 and the exhaust port 33, and between the second limit plate 45 and the mounting plate 4. For example, those skilled in the art may adopt an integrated setting or welding and other connection methods. Such adjustments and changes to the specific connection methods between the first limit plate 34 and the exhaust port 33, and between the second limit plate 45 and the mounting plate 4 do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0070] Preferably, if Figure 5 and Figure 6 As shown, the pipeline machine of the utility model also includes fixing bolts. First fixing holes 341 are provided at both ends of the first limiting plate 34, and second fixing holes 4521 are provided on the second limiting plate 45. The fixing bolts pass through the first fixing holes 341 and the second fixing holes 4521 to fix the first limiting plate 34 and the second limiting plate 45.

[0071] For example, Figure 5 and Figure 6 As shown, first fixing holes 341 are provided at both ends of the first limiting plate 34, and second fixing holes 4521 corresponding to the first fixing holes 341 are provided on the second limiting plate 45. When the two ends of the first limiting plate 34 are abutted against the corresponding second limiting plate 45, the first fixing hole 341 is just aligned with the second fixing hole 4521, and fixing bolts (not shown in the figure) pass through the first fixing hole 341 and the second fixing hole 4521 to fix the first limiting plate 34 and the second limiting plate 45.

[0072] Preferably, if Figure 5and Figure 6 As shown, the second limiting plate 45 of the present invention includes a connecting portion 451 and a limiting portion 452 that are connected to each other. The connecting portion 451 is fixedly connected to the mounting plate 4 , and the limiting portion 452 is in contact with the first limiting plate 34 .

[0073] For example, Figure 5 and Figure 6 As shown, the connecting portion 451 is fixedly mounted on the mounting plate 4 in the horizontal direction, the limiting portion 452 is arranged in the vertical direction and is abutted against the first limiting plate 34, the second fixing hole 4521 is arranged on the limiting portion 452, and the bottom end of the limiting portion 452 is provided with a limiting edge 4522 inclined forward, which can limit the movement of the first limiting plate 34 in the vertical direction.
