Abstract
The utility model relates to an improved structure for bellows of an air-blower. The utility model has the key point that two sides of a spiral base plate are respectively welded with a front and a back side plates to form a spiral bellow body. The utility model is characterized in that two side edges of the base plate are folded and curved into a rail groove; the width of the rail groove is equal to the thickness of the front and the back side plates to make the front and the back side plates respectively, tightly and firmly inserted in the rail groove; then, the utility model is shaped by welding at joints by the welding manners of spot welding (Spot), or oxyacetylene welding, or argon welding (TIG), or carbon dioxide welding (CO2), or copper braze welding (vacuum welding), etc.
Description
The utility model is to exhale novel blower housing structure, relates to the blower design field.
Traditional blower wind box structure is shown in Fig. 5,6, structure shown in Figure 5 is burn-on respectively in spiral type substrate (A) both sides front side plate (B) and back side panel (C), the necessary complete all solid weldings in its joining portion, do not make leakage, if failure welding, the slit is arranged slightly, the noise of then when air blast, empathizing, and the rigidity of this structure is relatively poor.Structure shown in Figure 6 is to bend to 90 ° flanging (E) respectively at spiral type substrate (D) dual-side, forward and backward side plate (F) burn-on then in the flanging inboard (G), to increase rigidity,, causes the forward and backward side plate of this kind structure be full of cracks but often being moved in the suction when air blast.
The purpose of this utility model is to be improved at the defective of above-mentioned two kinds of structures, so that the raising of blower wind box rigidity is easily manufactured, stops to leak.
The purpose of this utility model realizes by following manner, fold together and the wide rail groove of forward and backward side plate thickness spiral type substrate both sides of the edge are crooked respectively, in the forward and backward side plate difference close and firm ground embedded groove, use spot welding (Spot) then, or use oxy-acetylene welding, or with argon arc welding (TIG), or with carbon dioxide (CO
2) weldering, or with the in addition seam moulding of red metal hard solder welding manners such as (vacuum weldings).The utility model substrate has preferable gripping force, and is convenient to carry out further solder attachment processing, comes off so be difficult for producing.
Description of drawings:
Fig. 1 is the A-A place sectional view of the utility model Fig. 2.
Fig. 2 is a front elevation of the present utility model.
Fig. 3 is a profile of the present utility model.
Fig. 4 is a combination partial sectional view of the present utility model.
Fig. 5 represents the combination partial sectional view of the wind box of traditional drum blower fan.
Fig. 6 represents the wind box combination partial sectional view of another kind of traditional drum blower fan.
1 is substrate among the figure, and 2 is front side plate, and 3 is back side panel, and 11 is the rail groove, and 10 is wind box.
Shown in Fig. 1~4, blower wind box of the present utility model is the substrate 1 of spiral type by one and welds front side plate 2 and the back side panel 3 established respectively in its both sides and formed, it is characterized in that: substrate 1 both sides of the edge are crooked respectively to fold together and the wide rail groove 11 of the thickness of forward and backward side plate 2,3, so that front side plate 2 and back side panel 3 difference close and firm embed in the rail groove 11, and betwixt with spot welding or oxy-acetylene welding, or carbon dioxide arc welding, or red metal hard solder welding manner seam moulding such as (vacuum weldings).
By said structure as can be known, bellows of air-blower structure-improved of the present utility model has the rigidity height, and is easily manufactured, the advantage of stopping to leak.
Claims (1)
- Blower wind box 10 be the substrate 1 of spiral type by one and on substrate forward and backward both sides weld front side plate 2 and the back side panel 3 established respectively and formed, it is characterized in that: substrate 1 both sides of the edge are crooked respectively to fold together and the wide rail groove 11 of the thickness of forward and backward side plate 2,3, forward and backward side plate 2,3 close and firm respectively embeds in the rail groove 11, and betwixt with welding manner seam moulding.
