Abstract
The utility model discloses a plastic motor fan, which includes blades and a fan body, wherein the inner wall of an inner hole of the fan body is raised inwards to form a bulge; and the bulge forms a flat key structure connected onto the fan body. According to the utility model, the bulge on the fan body forms the flat key structure connected onto the fan body, so that when the fan is assembled on a shaft of the motor, no additional flat key is needed to be equipped, which is trouble-saving; and when the motor is in normal use, the bulge on the fan body does not fall off, and the normal use of the motor fan is guaranteed.
Description
Technical field
The utility model relates to a kind of electrical motor fan.
Background technique
Electrical motor fan is used for the cooling of motor.Electrical motor fan generally is connected on motor reel by flat key, and in use there is certain defective in this structure commonly used, and the one, prepare flat key, more bothersome, the 2nd, flat key comes off sometimes, affects the normal use of electrical motor fan.
The model utility content
The utility model provides a kind of simple in structure for the deficiencies in the prior art, can solve that flat key preparation is bothersome, the motor plastic fan of the problem that may come off in using.
The utility model is achieved through the following technical solutions technical goal.
The motor plastic fan comprises flabellum, fan body; Its improvements are: described fan body endoporus inwall inwardly protruding forms thrust, and described thrust forms the flat key structure that is connected on fan body.
In said structure, described thrust one end is provided with and imports end, and described importing end is arranged on fan body a side opposing with flabellum.
The utility model compared with prior art has following good effect:
1. fan body upper process thing forms the flat key structure that is connected on fan body, when being assembled to like this on motor reel, need not to prepare in addition flat key, relatively saves trouble.
2. when motor normally used, fan body upper process thing can not come off, and had guaranteed the normal use of electrical motor fan.
3. thrust one end is provided with and imports end, makes the utility model ratio be easier to be assembled on motor reel.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view in Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
Motor plastic fan shown in the drawings comprises flabellum 1, fan body 3; Fan body 3 endoporus inwall inwardly protrudings form thrust 2, thrust 2 forms the flat key structure that is connected on fan body 3, in order to facilitate being connected of the utility model and motor reel, thrust 2 one ends are provided with and import end 4, import end 4 and are arranged on fan body 3 side opposing with flabellum 1.
The utility model fan body 3 upper process things 2 form the flat key structure that is connected on fan body 3, when being assembled to like this on motor reel, need not to prepare in addition flat key, relatively save trouble; When motor normally used, fan body 3 upper process things 2 can not come off, and have guaranteed the normal use of electrical motor fan.
