Abstract
The utility model relates to a fan outer casing, which comprises an assembled casing body. Net covers are arranged on two sides of the casing body, a mounting seat is arranged at the assembly position of the casing body, a connector is arranged on the mounting seat, a slot is arranged on the inner surface of the casing body, a boss matched with the slot is arranged on the outer edge of each net cover, the boss on the outer edge of the net cover is provided with at least one radial bumps, at least one recess is arranged on the slot, and the radial bumps are matched with the recesses in size. The radial bumps are arranged on the bosses on the outer edges of the net covers, the radial recesses are arranged the bottom of the slot, the net covers cannot easily rotate by peripherally positioning the net covers through the bumps and the recesses in mutual matching after installation, and matching between the net covers and the casing body is more stable.
Description
Technical field
The utility model relates to a kind of shell, relates in particular to a kind of flow blower casing.
Background technique
In the prior art, flow blower casing comprises spliced housing, described housing is provided with guard, splicing place of spliced housing is provided with fitting seat, the internal surface of housing is provided with groove, and the outer of guard is provided with the boss that matches with groove, and boss embeds groove, can play the effect of leaking out of preventing, by bayonet connection two housing sections being linked together gets final product.Though this shell has the easy advantage of dismounting, but also have the following disadvantages: the boss of the groove of shell inner surface and guard outer is circular arc, can not circumferentially locate guard, after guard is installed by the groove fit on boss and the housing, guard rotates easily, and promptly guard is stable inadequately with cooperating of housing.
The model utility content
The utility model is circular arc at the groove of existing Blower Housing internal surface and the boss of guard outer, can not circumferentially locate guard, after guard is installed by the groove fit on boss and the housing, guard rotates easily, be guard and the stable inadequately deficiency that cooperates of housing, provide a kind of guard to cooperate comparatively stable flow blower casing with housing.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of flow blower casing comprises spliced housing, the both sides of described housing are provided with guard, splicing place of described housing is provided with fitting seat, described fitting seat is provided with link, the internal surface of described housing is provided with groove, the outer of described guard is provided with the boss that matches with groove, the boss of described guard outer is provided with at least one radial projection, described groove is provided with at least one pit, and the size of described radial projection and the size of pit are complementary.
The beneficial effects of the utility model are: the utility model flow blower casing is provided with radial projection on the boss of guard outer, be provided with radially pit in the bottom of groove, after the installation, guard is circumferentially located with matching of pit by projection, guard is not easy to rotate, and guard is just comparatively stable with cooperating of housing.
Further, described flow blower casing comprises first projection and second projection, and described first projection and second projection are symmetrical arranged along the circumference of guard outer.
Further, described flow blower casing comprises first pit and second pit, and described first pit and second pit are symmetrical arranged along the circumference of groove.
Further, have at least two straight flanges on the boss of described guard outer, described groove is provided with at least two straight troughs that are complementary with straight flange.
Further, described straight flange is two, and described two straight flanges are symmetrical arranged along the outer of guard, and described straight trough also is two, and described two straight troughs are symmetrical arranged along the circumference of groove.
