Abstract
The utility model discloses an anti-loose structure of an insertion hole of a rotation shaft of motor fan blades. The anti-loose structure of the insertion hole of the rotation shaft of the motor fan blades comprises fan blades, a square metal gasket and reinforced ribs of the fan blades and is characterized in that one end of the insertion hole of the rotation shaft of the fan blades is embedded in the square metal gasket. The shape of an inner hole of the metal gasket is the same with that of an original insertion hole of the rotation shaft and the inner hole and the original insertion hole are concentric. The thickness of the metal gasket is 3mm. Four reinforced ribs are arranged on the fan blades along directions of four corners of the square metal gasket. The anti-loose structure of the insertion hole of the rotation shaft of the motor fan blades has the advantages that compared with the structure of an insertion hole of the rotation shaft of fan blades of an existing dehumidifier, the capability of resisting torsion generated when the fan blades rotate in a high speed is enhanced and radiating capability of the insertion hole of the rotation shaft is improved. Thus, the fan blades does not deform and loosen in a long time running, service life of the fan blades of the dehumidifier is prolonged and product reputation of the dehumidifier is improved.
Description
Technical field
The utility model relates to fan manufacturing technology, particularly relates to a kind of manufacturing technology of rotating shaft jack of dehumidifier fan leaf.
Background technique
The heat of existing dehumidifier motor passes to the rotating shaft jack of fan leaf through rotating shaft, the rotating shaft diameter of motor is thinner, and plastic fan blade is larger, the easy temperature distortion of rotating shaft jack of fan leaf, after having used of a specified duration, the rotating shaft jack of fan leaf is because the impact of being heated for a long time, can distortion under the effect of warping force, become large even loosening, produce machine shaft can not with fan leaf rotate technical problem.
The model utility content
The utility model provides a kind of rotating shaft jack anti-loose structure of motor ventilating fan leaf for the rotating shaft jack that solves above-mentioned dehumidifier fan leaf produces in the running distortion, becomes large, loosening problem.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of rotating shaft jack anti-loose structure of motor ventilating fan leaf comprises the stiffening rib on fan leaf, square-shaped metal packing ring and the fan leaf.It is characterized in that: at rotating shaft jack one end of described fan leaf, embed a square-shaped metal packing ring, the shape of described metal washer endoporus is the same with original rotating shaft jack and be concentric, the thickness of metal washer is at 3mm, and the direction along four angles of square of metal washer on fan leaf is provided with 4 stiffening ribs.
Useful effect is: the utility model is compared with the rotating shaft jack structure of existing dehumidifier fan leaf, because rotating shaft jack one side on the fan leaf embeds a square-shaped metal packing ring, set up stiffening rib at fan leaf, strengthened the ability of the torsion that the opposing fan leaf produces when High Rotation Speed, make the rotating shaft jack increase heat dissipation potential, reach the purpose that fan leaf can not be out of shape and become flexible under long-term operation, improved the life-span of dehumidifier fan leaf, improved the product image of dehumidifier.
Description of drawings
Fig. 1 is the schematic representation that the utility model fan leaf embeds square-shaped metal packing ring and increase stiffening rib.
Fig. 2 is square-shaped metal packing ring schematic representation of the present utility model.
Embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing 1, accompanying drawing 2 and an embodiment:
As shown in Figure 1 and Figure 2, a kind of rotating shaft jack anti-loose structure of motor ventilating fan leaf comprises the stiffening rib 3 on fan leaf 1, square-shaped metal packing ring 2 and the fan leaf.It is characterized in that: rotating shaft jack 4 one ends of described fan leaf 1, embed a square-shaped metal packing ring 2, endoporus 4 ' the shape of described metal washer 2 and original rotating shaft jack 4 are the same and be concentric, the thickness of metal washer 2 is at 3mm, and the direction along four angles of square of metal washer 2 on fan leaf is provided with 4 stiffening ribs 3.
Claims (1)
