[0002] As we all know, the traditional axial flow fan duct is a cylinder surrounded by metal plates. The axial flow fan is installed inside the cylinder, and the side wall of the cylinder is provided with a junction box. Since the surface of the cylinder is not flat, the installation of the junction box , it is necessary to weld a junction box mounting plate on the outer wall of the cylinder, and then fix the junction box on the junction box mounting plate. The disadvantage is that the structure is unreasonable. Welding deformation not only affects the appearance, but also takes a long time to work, wastes raw materials and increases equipment costs

Embodiment Construction
[0014] Below in conjunction with accompanying drawing, the present invention is further described:
[0015] as attached figure 2 As shown, an axial flow fan cylinder includes a cylinder body 1, which is characterized in that the wall of the cylinder body 1 is provided with an outwardly bulging junction box mounting plate 2, and the junction box mounting plate 2 is square , the junction box mounting plate 2 is provided with a junction box Glen hole and a junction box installation hole.
[0016] According to the present invention, the cylinder body 1 of the air cylinder and the mounting plate 2 of the junction box are formed by stamping at one time.
[0017] When the invention is installed, the motor junction box can be directly fixed on the junction box installation plate, which avoids the shortage of deformation of the blower barrel during welding.
[0018] Due to the adoption of the above structure, the present invention has the advantages of simple structure, compact and ...

The invention relates to the technical field of axial flow fans, in particular to an air duct of an axial flow fan. The air duct comprises an air duct body and is characterized in that the duct wall of the air duct body is provided with an externally protruded terminal box mounting panel, and the terminal box mounting panel is square-shaped and is provided with terminal box flange holes and terminal box mounting holes. Based on the above structure, the air duct of the axial flow fan has the advantages that the structure is simple, the appearance is compact and attractive, the original material is saved, the device cost is saved, the production efficiency is improved and the like.
Description
technical field [0001] The invention relates to the technical field of axial flow fans, in particular to an axial flow fan cylinder which is easy to manufacture. Background technique [0002] As we all know, the traditional axial flow fan duct is a cylinder surrounded by metal plates. The axial flow fan is installed inside the cylinder, and the side wall of the cylinder is provided with a junction box. Since the surface of the cylinder is not flat, the installation of the junction box , it is necessary to weld a junction box mounting plate on the outer wall of the cylinder, and then fix the junction box on the junction box mounting plate. The disadvantage is that the structure is unreasonable. Welding deformation not only affects the appearance, but also takes a long time to work, wastes raw materials and increases equipment costs. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and pro...
