Abstract
The utility model relates to a fan outer shell, which comprises an annular shell, wherein a plurality of screw holes are arranged on the shell, a plurality of grooves are circumferentially arranged on the inner wall of the shell, and the screw holes are positioned in the grooves. By adopting the technical scheme, the utility model provides the fan outer shell which can be used for well positioning a fan-blade bracket.
Description
Technical field
The utility model relates to fan art, particularly a kind of fan drum.
Background technique
Along with scientifically constantly development, because the fan low price, effect is also relatively good, has spread in each family.
Fan generally comprises shell, motor, fan blade, is used to install the fan blade arm of fan blade, fan blade arm is generally radial, wherein shell includes the housing of ring-type, the sidewall of housing is provided with the some tapped holes that are used for fixing fan blade arm, because fan blade arm is directly fixed by screw or bolt part, when fan blade is rotated, its poor stability, can not well fan blade arm be located, thereby influence the performance of fan, heavy then cause unnecessary damage.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of fan drum that can locate fan blade arm well.
The technical solution of the utility model: a kind of fan drum, include the housing of ring-type, described housing is provided with some tapped holes, circumferentially is provided with some grooves on the described inner walls, and described tapped hole is positioned at described groove.
Adopt technique scheme, fan blade arm is snapped in the described groove, fix fan blade arm by fixed blocks such as screw or bolts again, except screw or bolt part play the fixation, the inwall of groove also can be played a supporting role to fan blade arm, makes that the fan blade rotation is more stable.
Further improvement of the utility model: described groove is four and circumferentially evenly distributes along inner walls.
Adopt above-mentioned further improvement, four grooves be set just can satisfy fixing to fan blade arm well, groove along inner walls circumferentially evenly distribution can guarantee the steadily of centre of gravity of whole fan to make that the fan blade rotation is more reliable.
Further improvement more of the present utility model: described tapped hole is four, places respectively in four grooves.
Adopt above-mentioned further improvement again, a screw only is set in each groove, can not only locate fan blade arm well, also can reduce cost.

Embodiment
As shown in Figure 1, 2, 3, a kind of fan drum includes the housing 1 of ring-type, and described housing 1 is provided with some tapped holes 2, circumferentially is provided with some grooves 3 on described housing 1 inwall, and described tapped hole 2 is positioned at described groove 3.In the utility model specific embodiment, described groove 3 is a rectangular recess.
In the utility model specific embodiment, described groove 3 is four and circumferentially evenly distributes along housing 1 inwall.Fan blade arm is radial, and four radiation items are arranged, and every radiation item end of fan blade arm is placed in the groove 3 get final product.
In the utility model specific embodiment, described tapped hole 2 is four, places respectively in four grooves 3.Screw is inserted in the corresponding tapped hole 2, make housing 1 fixedly connected can to realize fixedly connected to fan blade with the radiation item of fan blade arm, the fan spin stabilization of this structure, the polarization of fan blade arm is good.
