Technical field
This utility model relates to Fan Equipment field, especially relates to the fan blade on a kind of blower fan.
Background technology
Blower fan generally comprises fan blade and air-ducting ring, and air-ducting ring is used for fixing fan blade, and just wind produced by fan blade carries outward by air-ducting ring, plays certain assosting effect；So while air-ducting ring plays fixing fan blade, also function to certain auxiliary wind-guiding, and be typically all between existing air-ducting ring and fan blade and be fixed by bolt or screw, additionally when fan blade is under long-term operating at a high speed, compare thin with only adding by screw between air-ducting ring to be solidly connected and be easy to breakage, particularly at the position connected, cause fan blade to loosen and then produce the biggest noise, so the applicant proposes improvement with regard to this, prestige can solve problem present in these existing products.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, fan blade on a kind of blower fan is provided, can solve the problem that weak point of the prior art, not only facilitate and be connected installation with air-ducting ring, and can reduce and loosen the noise of generation after long-term use owing to installing the best.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of fan blade on blower fan, including installation end, the outer wall at described installation end is formed around the fan blade arranged at equal intervals, it is characterised in that: the bottom of described installation end is formed and extends axostylus axostyle, and the inside of described extension axostylus axostyle is provided with the axis hole matched with motor；Also include installing rack, described installing rack includes mounting cylinder, the many connecting rods arranged at equal intervals it are formed around in the bottom of described mounting cylinder, the end of many connecting rods is provided with shared ring for fixing, 2 bearings it are provided with between the inside of described mounting cylinder and described installation end, being provided with 2 bearings between described extension axostylus axostyle and described mounting cylinder, the bottom terminal ends of described extension axostylus axostyle is exposed on the bottom face of described mounting cylinder.
Doing this utility model further preferably, described installing ring is formed in one with described connecting rod.
Doing this utility model further preferably, the upper and lower surface of described fan blade is provided with wind guide tank, and the bottom surface of described wind guide tank is arcuate groove, and one end is stub end, and the other end is little head end.
This utility model is done further preferably, between described installation end and described fan blade, be provided with reinforcement.
Doing this utility model further preferably, the outer surface of described fan blade is provided with noise reduction layer.
Doing this utility model further preferably, the outer surface of described fan blade is provided with antirust coat.
Compared with prior art this utility model is reached to provide the benefit that:
The bottom of installation end described in this utility model is formed and extends axostylus axostyle, and the inside of described extension axostylus axostyle is provided with the axis hole matched with motor；Also include installing rack, described installing rack includes mounting cylinder, the many connecting rods arranged at equal intervals it are formed around in the bottom of described mounting cylinder, the end of many connecting rods is provided with shared ring for fixing, 2 bearings it are provided with between the inside of described mounting cylinder and described installation end, being provided with 2 bearings between described extension axostylus axostyle and described mounting cylinder, the bottom terminal ends of described extension axostylus axostyle is exposed on the bottom face of described mounting cylinder；This utility model is by be socketed in outside ventilating duct by installing ring, again by bolt by together with fixing to installing ring and ventilating duct, so sound construction of entirety, erection space each other expands significantly, based on fan blade one stable operation platform of operating, extend overall service life.Realize stablizing between installation end and mounting cylinder rotating freely additionally by 4 bearings, such fan blade stability of rotation, reduce noise, also reduce due to loosening that instability rotation causes simultaneously.Just match with installation end, extension axostylus axostyle inside ventilating duct in this utility model, connected by bearing between the two and rotate relatively freely.Installation end in this utility model is limited in mounting cylinder by bearing with extending axostylus axostyle, will not shift or disengage, but can be freely rotatable.
It follows that this utility model can solve the problem that weak point of the prior art, not only facilitate and be connected installation with air-ducting ring, and can reduce and loosen the noise of generation after long-term use owing to installing the best.
