Abstract
The utility model relates to the technical field of axial flow fans, in particular to an air cylinder of an axial flow fan. The air cylinder comprises an air cylinder body. The air cylinder is characterized in that a junction box mounting plane protruding outwards is arranged on the cylinder wall of the air cylinder boy, the junction box mounting plane is square, and a junction box gland hole and a junction box mounting hole are reserved in the junction box mounting plane. Due to adoption of the structure, the air cylinder has the advantages that the air cylinder is simple in structure and compact and attractive in appearance, raw materials are saved, equipment cost is reduced, production efficiency is improved and the like.
Description
Technical field
The utility model relates to the axial-flow blower technical field, specifically a kind of axial-flow blower air duct easy to make.
Background technique
As everyone knows, traditional axial-flow blower air duct is to crowd around the cylindrical shell that forms by sheet metal, inner barrel installation shaft flow fan, cylinder lateral wall is provided with terminal box, because drum surface is not the plane, therefore, when terminal box is installed, need flat board be installed in outer wall welding one terminal box of cylindrical shell, and then terminal box is fixed on the terminal box installation flat board, its deficiency is: unreasonable structure, when the welding terminal box is installed flat board, make air duct have welding deformation easily, not only influence attractive in appearance, and man-hour is very long, waste raw material, increase equipment cost.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, compact appearance is attractive in appearance, the axial-flow blower terminal box mounting plate that saves material, reduce equipment cost, enhance productivity.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of axial-flow blower air duct comprises the air duct cylindrical shell, it is characterized in that the barrel of air duct cylindrical shell is provided with the terminal box mounting plane of outwards heaving, and the terminal box mounting plane is square, and the terminal box mounting plane is provided with terminal box Ge Lan hole and terminal box mounting hole.
Air duct cylindrical shell described in the utility model and terminal box are installed mounting plane by the punching press once-through.
The utility model has been avoided the deficiency of air duct cylindrical shell distortion when welding owing to adopt said structure, have simple in structure, compact appearance is attractive in appearance, save material, man-hour is short, reduce equipment cost, advantage such as enhance productivity.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the enlarged view of A among Fig. 1.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the enlarged view of X among Fig. 3.
Reference character: air duct cylindrical shell 1, terminal box mounting plane 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 2, a kind of axial-flow blower air duct comprises air duct cylindrical shell 1, it is characterized in that the barrel of air duct cylindrical shell 1 is provided with the terminal box mounting plane of outwards heaving 2, terminal box mounting plane 2 is square, and terminal box mounting plane 2 is provided with terminal box Ge Lan hole and terminal box mounting hole.
Air duct cylindrical shell 1 described in the utility model and terminal box mounting plane 2 are by the punching press once-through.
The utility model can directly be fixed on connection box for motor on the terminal box mounting plane when mounted, has avoided the deficiency of air duct cylindrical shell distortion when welding.
The utility model is owing to adopt said structure, have simple in structure, compact appearance is attractive in appearance, save material, man-hour is short, reduce equipment cost, advantage such as enhance productivity.
