Abstract
The utility model discloses an inner flanging air duct which comprises a fan cover and a net bottom. A flanging is arranged at the bottom of the fan cover, the flanging is vertically connected with the inner side wall of the fan cover, and the net bottom is arranged on the vertical connection portion. The flanging is in a circular ring shape, and the wall thickness of the flanging is 10mm. The inner flanging air duct is simple in structure and high in overall strength.
Description
Technical field
The utility model relates to blower fan technical field, is specifically related to a kind of in-flanges air duct.
Background technique
After fan housing moulding, directly net bottom is welded in to fan housing bottom, in gap, place is filled up with putty.Blower fan uses cylindrical place, initial stage bottom intact, and long-play is due to external environment factor and self vibration, and putty can split, and net bottom bulk strength is impaired.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of in-flanges air duct is provided, and the utility model is simple in structure, and bulk strength is high.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
An in-flanges air duct, comprises fan housing and net bottom, and described fan housing bottom is provided with flange, and described flange is connected with fan housing madial wall is vertical, and is provided with net bottom in vertical joint.
Further, described flange be shaped as ring, and wall thickness is 10mm.
The beneficial effects of the utility model are:
Can reduce in process of production and mend this procedure of putty, fan housing net bottom is also protected, and bulk strength is high, and fan housing integral body looks attractive in appearance.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is front view of the present utility model;
Fig. 2 is side cross-section schematic diagram of the present utility model.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1 and Fig. 2, a kind of in-flanges air duct, fan housing 1 bottom inside is provided with flange 3, and flange 3 and vertical connection of fan housing 1 madial wall, be shaped as ring, and wall thickness is 10mm, and net bottom 2 is arranged on the vertical joint that flange 3 forms with fan housing 1 madial wall.
The working principle of the present embodiment is as follows:
As shown in Figure 2, blower fan is in running, and net bottom 2 is subject to resistance, by flange 3, net bottom 2 outer rings is wrapped up completely, and resistance discharges by flange 3, has greatly reduced the direct stressed degree of net bottom 2, and without using putty to fill up defect, strength increase and attractive in appearance.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
