Abstract
The utility model relates to a fan blade structure, which comprises a fan blade (1), a metal shaft sleeve (2) for installing a rotation shaft of a motor and a fan blade drum outer sleeve (3) integrated with the fan blade (1) and is sheathed outside the metal shaft sleeve (2), wherein a threaded hole (21) for locking the rotation shaft is arranged on the metal shaft sleeve (2). The fan blade structure is characterized in that a plastic sleeve (4) is arranged between the metal shaft sleeve (2) and the fan blade drum outer sleeve (3). As the outer diameter of the metal shaft sleeve (2) is reduced, the material is saved, the production cost is reduced, and the injection molding production efficiency and product quality are improved.
Description
Technical field
The utility model relates to a kind of flabellum mechanism.
Background technique
At present, the flabellum mechanism of electric fan comprises the metal axle sleeve of fixing with machine shaft and is located at the outer plastic parts of axle sleeve.The wall of the metal axle sleeve of this structure is thicker, and relatively waste material, so cost also improves relatively.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of flabellum mechanism that can proof strength can save material is provided.
In order to achieve the above object, the utility model is to realize like this, it is an a kind of flabellum mechanism, the outer flabellum circle of metal axle sleeve that is set in that metal axle sleeve reaches and flabellum is connected as a single entity that comprises flabellum, installation machine shaft rouses overcoat, on metal axle sleeve, be provided with the tapped hole that the locking rotating shaft is used, it is characterized in that: between metal axle sleeve and flabellum circle drum overcoat, also be provided with a plastic sheath.
Described metal axle sleeve is positioned at the wall thickness of the wall thickness of tapped hole position greater than other position.
The U-shaped enlarging that has on the above-mentioned plastic sheath, the U-shaped enlarging is facing to the position of the tapped hole on the metal axle sleeve.
The utility model advantage compared with prior art is, because plastic sheath has been arranged, reduced the external diameter of metal axle sleeve, saved material, reduced cost of production, and effectively prevented because of the too thick product shrink that causes of flabellum circle drum overcoat and the problem of cooling and shaping difficulty, thereby improved injection moulding manufacturing efficiency and quality.
Description of drawings
Fig. 1 is an axial sectional view of the present utility model;
Fig. 2 is the explosive view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
Shown in Fig. 1 to 2, it is an a kind of flabellum mechanism, comprise flabellum 1, the metal axle sleeve 2 of installation machine shaft reaches the flabellum circle that is set in outside the metal axle sleeve 2 that is connected as a single entity with flabellum 1 and rouses overcoat 3, on metal axle sleeve 2, be provided with the tapped hole 21 that the locking rotating shaft is used, characteristics of the present utility model are: also be provided with a plastic sheath 4 between metal axle sleeve 2 and flabellum circle drum overcoat 3, therefore can reduce the external diameter of metal axle sleeve 2, the thickness of the flabellum circle drum overcoat 3 that is produced in the time of also can reducing injection moulding, thereby can prevent to have improved manufacturing efficiency and quality of product because of the too thick product that causes of flabellum circle drum overcoat shrinks and distortion.
In the present embodiment,, be positioned at the wall thickness of the wall thickness of tapped hole 21 positions greater than other position at metal axle sleeve 2 for the intensity of reinforcement metal axle sleeve 2.The U-shaped enlarging 41 that has on the plastic sheath 4, U-shaped enlarging 41 are facing to the position of the tapped hole 21 on the metal axle sleeve 2, and it is also thereon fastening to make things convenient for plastic sheath 4 to be set on the metal axle sleeve 2.
During production, earlier plastic sheath 4 is set on the metal axle sleeve 2, is placed in the injection mould injection moulding again and moulds the flabellum finished product, by High Temperature High Pressure metal axle sleeve 2, plastic sheath 4 and flabellum circle drum overcoat 3 are fixed together during injection moulding.
Claims (3)
1, a kind of flabellum mechanism, the outer flabellum circle of metal axle sleeve (2) that is set in that metal axle sleeve (2) reaches and flabellum (1) is connected as a single entity that comprises flabellum (1), installation machine shaft rouses overcoat (3), on metal axle sleeve (2), be provided with the tapped hole (21) that the locking rotating shaft is used, it is characterized in that: between metal axle sleeve (2) and flabellum circle drum overcoat (3), also be provided with a plastic sheath (4).
2, flabellum according to claim 1 mechanism, it is characterized in that: described metal axle sleeve (2) is positioned at the wall thickness of the wall thickness of tapped hole (21) position greater than other position.
3, flabellum according to claim 1 mechanism is characterized in that: the U-shaped enlarging (41) that has on the above-mentioned plastic sheath (4), U-shaped enlarging (41) is facing to the position of the tapped hole (21) on the metal axle sleeve (2).
