Abstract
The utility model relates to a kind of mounting point of spiral case, comprises spiral case, snail tongue, outer casing, outer casing side plate, outer casing top board; Described spiral case is connected by the first via hole with described outer casing side plate, and described spiral case is connected by the second via hole with described outer casing top board, and described spiral case is two of positioned opposite; Solve the problem that windage is large, noise is large; Noise is little, Wind Volume, low cost.
Description
Technical field
The utility model belongs to Fan Equipment field, is specifically related to a kind of mounting point of spiral case.
Background technique
When the spiral case of existing blower fan there will be work conventionally, also there is the problem that noise is larger in large, the problem that affects air quantity of Velocity Profiles inequality, windage.
Model utility content
The purpose of this utility model is to provide that a kind of noise is little, Wind Volume, the mounting point of spiral case cheaply.
The technological scheme that realizes the utility model object is: a kind of mounting point of spiral case, comprises spiral case, snail tongue, outer casing, outer casing side plate, outer casing top board; Described spiral case is connected by the first via hole with described outer casing side plate, and described spiral case is connected by the second via hole with described outer casing top board, and described spiral case is two of positioned opposite.
Preferred described the first via hole is 4, and for the rivet of diameter 3.2mm is installed, described the second via hole is 12, for the rivet of diameter 3.2mm is installed; The radius of arc of described snail tongue is 12mm; Described snail tongue is 60mm apart from flabellum along the perpendicular distance of longitudinal axis.
The utlity model has positive effect: the Position Design cost of this spiral case is very low, can in the situation that not changing power, promote air quantity, guiding air-flow, reduces noise to a great extent.
