Abstract
The utility model proposes a kind of blower fan flange plate, comprise annular disk body, the annular boss matched with described annular disk body inner ring periphery, outer bolt hole is provided with at edge, described disk body outer ring, described disk body adopts four pieces of segmentation flanges be threaded connection and formed, the described groove referring to and be provided with a connection at adjacent two pieces of segmentation flanges that is threaded, and in two pieces of segmentation flanges below described groove, screw is set respectively, the connecting plate that shape and described groove shapes match is placed in described groove, described connecting plate is also provided with the attachment hole corresponding with described screw, described segmentation flange to be connected with bolt through connecting plate and to form described disk body, the inner ring edge of described disk body is provided with Inner bolt holes, in described boss, be provided with the attachment hole corresponding with described Inner bolt holes, and described disk body is connected through bolt with described boss.Blower fan flange plate involved by the utility model adopts and is threaded, and avoids the internal stress that welding produces, makes flange plate not yielding.
Description
Technical field
The utility model relates to flange plate, particularly relates to a kind of blower fan flange plate.
Background technique
At present, the flange plate of blower fan is normally processed by monoblock blank material, and the flange plate made in this way is yielding, and scrap rate is high, and manufacture cost is high.
Model utility content
The utility model proposes a kind of blower fan flange plate, to save material, easily process, reduce fabricating cost.
To achieve these goals, the utility model proposes a kind of blower fan flange plate, comprise annular disk body, the annular boss matched with described annular disk body inner ring periphery, outer bolt hole is provided with at edge, described disk body outer ring, described annular disk body adopts four pieces of segmentation flanges be threaded connection and formed, the described groove referring to and be provided with a connection at adjacent two pieces of segmentation flanges that is threaded, and in two pieces of segmentation flanges below described groove, screw is set respectively, the connecting plate that shape and described groove shapes match is placed in described groove, described connecting plate is also provided with the attachment hole corresponding with described screw, described segmentation flange to be connected with bolt through connecting plate and to form described disk body, the inner ring edge of described annular disk body is provided with Inner bolt holes, in described annular boss, be provided with the attachment hole corresponding with described Inner bolt holes, and described annular disk body is connected through bolt with described annular boss.
The beneficial effect of the program of the present utility model is that the blower fan flange plate of said structure adopts thread connecting mode to be connected by four pieces of segmentation flanges, and disk body is connected with boss, avoid the internal stress that welding produces, make flange plate not yielding, the flange plate of said structure also has saving material, easy processing, the advantages such as fabricating cost is low.
Accompanying drawing explanation
Fig. 1 shows the overall structure schematic diagram of the blower fan flange plate involved by the utility model.
Fig. 2 shows the schematic diagram of the annular boss of the blower fan flange plate involved by the utility model.
Fig. 3 shows the schematic diagram of the disk body of the blower fan flange plate involved by the utility model.
Fig. 4 shows the schematic diagram of the disk body be threaded.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As Figure 1-3, blower fan flange involved by the utility model comprises annular disk body 2, the annular boss 1 matched with described annular disk body 2 inner ring periphery, edge, described disk body 2 outer ring is provided with outer bolt hole 3, its inner ring edge is provided with Inner bolt holes 5, in described annular boss 1, be provided with the attachment hole 4 corresponding with described Inner bolt holes 5.
In order to material saving, the annular disk body 2 involved by the utility model is spliced by four pieces of segmentation flanges 21, as shown in Figure 3.Concrete connecting method can adopt thread connecting mode.
As shown in Figure 4, the adjacent two pieces of segmentation flanges 21 be threaded are adopted to be provided with the groove 211 of a connection, and in two pieces of segmentation flanges 21 below described groove 211, screw 212 is set respectively, in concrete connection procedure, the connecting plate 6 of shape and described groove 211 mating shapes is placed in described groove 211, described connecting plate 6 is also provided with the attachment hole 61 corresponding with described screw 212, and described segmentation flange 21 to be connected with bolt 7 through connecting plate 6 and to form described disk body 2.
Because the inner ring edge of described annular disk body 2 is provided with Inner bolt holes 5, be provided with the attachment hole 4 corresponding with described Inner bolt holes 5 in described annular boss 1, therefore described annular disk body 2 is connected through bolt 7 with described annular boss 1.
Blower fan flange plate involved by the utility model adopts thread connecting mode to be connected by four pieces of segmentation flanges, and disk body is connected with boss, avoid the internal stress that welding produces, make flange plate not yielding, blower fan flange plate involved by the utility model also has saving material, easy processing, the advantages such as fabricating cost is low.
