Abstract
The utility model discloses an installation structure of an air blower shell. The installation structure of the air blower shell comprises a front shell and a rear shell, wherein the rear shell comprises a hollow rear base, the lower end of the rear base is opened, the front shell comprises a hollow front base which is matched with the rear base, a plurality of reinforcing ribs are arranged in inner cavities of the rear base and the front base, two first through holes which enable first bolts to conveniently pass through the inner wall of the front base are arranged on the rear base close to the side wall of the front base, bulges which are corresponding to the first through holes are extended on the front base, through holes are arranged on the bulges, the first bolts are connected on the bulges after passing through the first through holes to fix the rear base and the front base together, and the reinforcing ribs on the rear base are provided with depression portions which can be conveniently provided with the first bolts corresponding to the positions of the first through holes. The front base and the rear base are reliably connected through the first bolts, and are clung together, and the installation structure of the air blower shell can effectively reduce vibration of the front base and the rear base, and reduces noise of the front base and the rear base when working.
Description
Technical field
The utility model relates to the mounting structure of a kind of blower, particularly a kind of blower drum.
Background technique
The shell of blower generally comprises fore shell and back cover, fore shell comprises front base and front impeller holding part, back cover comprises rear base and rear impeller holding part, side at front impeller holding part and rear impeller holding part is provided with boss, fore shell and back cover are fixed together being used for, but on the front base of blower and rear base, generally do not utilize bolt that the two is fixed together, exist larger gap between front base and rear base, therefore blower is when work, the vibration of front base and rear base is very large, will cause like this noise very large, having influence on people works normally.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides blower drum with bolts between a kind of front base and rear base, the noise in the time of effectively reducing work.
The utility model solves the technological scheme that its technical problem adopts:
A kind of mounting structure of blower drum, comprise fore shell and back cover, described back cover comprises the rear base of hollow, the lower end of rear base is uncovered, described fore shell comprises the front base of the hollow matched with rear base, the inner chamber of rear base and front base is provided with many stiffening ribs, the sidewall of the close front base of rear base is provided with two and is convenient to first through hole of the first bolt through its sidewall, front base is extended with the first through hole protruding accordingly along the direction away from rear base on the close sidewall of rear base, described projection is provided with the first tapped hole, thereby the first bolt is through being connected to after the first through hole, projection is upper is fixed together rear base and front base, stiffening rib on described rear base is provided with in the position corresponding to the first through hole is convenient to the depressed part that the first bolt is installed.
In the utility model, the side of described back cover is provided with a plurality of the first boss, the first boss is provided with the second tapped hole, the side of fore shell is provided with and corresponding the second boss of the first boss, the second boss is provided with the second through hole, the second bolt is connected on the first boss through after the second through hole, thereby fore shell is fixed on back cover.
The beneficial effects of the utility model are: be connected by the first bolt between front base of the present utility model and rear base, connect reliably, front base and rear base are close together, and can effectively reduce the vibration of the two, the noise while reducing work.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of other direction of the present utility model.
Embodiment
As shown in Fig. 1 ~ Fig. 2, a kind of mounting structure of blower drum, comprise fore shell 1 and back cover 2, described back cover 2 comprises the rear base 3 of hollow, the lower end of rear base 3 is uncovered, described fore shell 1 comprises the front base 4 of the hollow matched with rear base 3, the inner chamber of rear base 3 and front base 4 is provided with many stiffening ribs 5, the sidewall of rear base 3 close front bases 4 is provided with two and is convenient to first through hole 6 of the first bolt through its sidewall, front base 4 is extended with and the corresponding projection 7 of the first through hole 6 along the direction away from rear base 3 on the close sidewall of rear base 3, described protruding 7 are provided with the first tapped hole 8, thereby the first bolt is fixed together rear base 3 and front base 4 through being connected to after the first through hole 6 on projection 7, stiffening rib 5 on described rear base 3 is provided with in the position corresponding to the first through hole 6 is convenient to the depressed part 9 that the first bolt is installed.As of the present utility model preferred, the side of described back cover 2 is provided with a plurality of the first boss 10, the first boss 10 is provided with the second tapped hole, the side of fore shell 1 is provided with and corresponding the second boss 11 of the first boss 10, the second boss 11 is provided with the second through hole 12, the second bolt is connected on the first boss 10 through after the second through hole 12, thereby fore shell 1 is fixed on back cover 2.Be connected by the first bolt between front base 4 of the present utility model and rear base 3, connect reliably, front base 4 and rear base 3 are close together, and can effectively reduce the vibration of the two, the noise while reducing work.
The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
