Abstract
The utility model relates to an electric fan with a plurality of adjustable fan blades. The electric fan is provided with a vertical rotating shaft, the lower end of the rotating shaft is provided with a fan disc, and the periphery of the fan disc is evenly provided with a plurality of fixed fan blades; the rotating shaft is externally connected a circular tube-shaped sliding sleeve in a sliding fit way; the fixed fan blades are externally and respectively connected with a plurality of drawing type movable fan blades by means of sliding fit, and the movable fan blades are fixed with the sliding sleeves by a plurality of connecting rods. The sliding sleeve is downwards pulled, so that the movable fan blades outwards and synchronously extend to be fixed, thus the area of the fan is enlarged; and the sliding sleeve is upwards pushed, so that the movable fan blades inwards retract to be overlapped with the fixed fan blades, and further the area of the fan is reduced. The electric fan with the adjustable fan blades is simple in structure, can adjust the area of the fan by conveniently adjusting the length of the fan blades to meet the requirements of the different situations, and achieves better effect of the fan by being matched with speed adjustment.
Description
Technical field
The utility model relates to a kind of electric fan, especially a kind of flabellum adjustable electric fan.
Background technique
Electric fan is subjected to liking of people as a kind of equipment of enjoying the cool very much, ceiling fan especially, and its pectinid area is big, and the wind speed gentleness has obtained popularizing widely, but can't regulate according to what of people, regulates the pectinid area.
The model utility content
In order to solve the problem that fan in use runs into, the utility model proposes a kind of flabellum adjustable electric fan, this fan structure is simple, can conveniently regulate the length of flabellum,, satisfy the demand of different situations to adjust the pectinid area, cooperate speed governing to use, reach better pectinid effect.
The technological scheme that its technical problem that solves the utility model adopts is: this flabellum adjustable electric fan comprises movable flabellum, connecting rod, fixedly flabellum, rotating shaft, sliding sleeve and fan dish; This electric fan has a vertical rotating shaft, and the lower end of this rotating shaft is equipped with the fan dish, and fixedly flabellum evenly is installed around this fan dish; The rotating shaft slide outside is connected with pipe shape sliding sleeve; Fixedly the outside of flabellum is slidingly connected with the movable flabellum of drawing and pulling type respectively, fixes with connecting rod between this activity flabellum and the sliding sleeve, and when needs strengthened the pectinid area, drop-down sliding sleeve, movable flabellum promptly can outwards stretch out fixing synchronously; When needs reduce the pectinid area, sliding sleeve is upwards boosted, movable flabellum promptly can be to the inside withdrawal with fixedly flabellum be overlapping.
The beneficial effects of the utility model are: this flabellum adjustable electric fan structure is simple, and the length that can conveniently regulate flabellum to adjust the pectinid area, satisfies the demand of different situations, cooperates speed governing to use, and reaches better pectinid effect.
Description of drawings
