Description
Technical field
The utility model relates to a kind of air bells conditioner, particularly relates to a kind of rotary blade fan, and it comprises housing, motor, is fixed on the blade on the motor output shaft.
Background technique
Existing rotary blade fan or be vertical or be desk-top is difficult to satisfy simultaneously different usage requirements.Notification number is that the Chinese utility model patent of CN2833197Y discloses a kind of folding fan.Include fan head, supporting post, foot rest part, wherein supporting post includes supporting post and following supporting post, is connected through folding header portion between supporting post and the two following supporting posts on two.Above-mentioned folding header portion includes upper beam and bottom end rail, and upper beam and bottom end rail are hinged through some loose-leaves, and upper beam is connected through the releasable connection part with bottom end rail.Above-mentioned foot rest partly is folding foot rest; This model utility adopts the two-part structure that is connected crossbeam through loose-leaf with the releasable connection part, when needing to fold fan, takes the releasable connection part apart; Two-part of crossbeam are opened, fan is fanned the folding effect of head part thereby reach.Though the foot rest of this model utility also adopts folding structure, when needing to fold, two-part of pulling foot rest upwards are folded into vertical state with foot rest, are convenient to store and carry.But this fan is difficult to the balanced support fan folding the back that rear leg is positioned at fan, can not make fan become desk-top use in the folding back of foot rest.In addition, this foot rest deflection one side is folding, and folding back structure can not be compact more, and can not have good outward appearance.
The model utility content
The technical problem that the utility model will solve provides a kind of rotary blade fan, and it is through to the architecture advances of support, support is had make fan to be vertical primary importance and makes fan be the desk-top second place.Simultaneously, make support when the second place through this structure, structure is more compact, makes things convenient for taking in and transporting of fan.
Another purpose of the utility model is the simple structure setting through support, increases the bearing strength of support when primary importance, and when the second place, improves the aesthetic appearance of fan.
The utility model technological scheme is: a kind of rotary blade fan comprises housing, motor, is fixed on the blade on the motor output shaft; Under said housing, be articulated with a support through a pivot; Be provided with an elastic positioning pin structure between said support and the housing; Said support comprises the primary importance that is positioned under the housing and spends the second place of facade to housing around said pivoted 180.Through the conversion between the primary importance and the second place of support, make this rotary blade fan promptly can be used as upright fan and use, can be used as the desk fan effect again.Simultaneously, through support in the second place, made things convenient for taking in of this rotary blade fan.
For the bearing strength that increases fan with to make support fan structure when the second place compact more, said support comprises first leg and second leg; Said first leg when the said second place corresponding to the front of said housing, said second leg when the said second place corresponding to the back side of said housing.
In order further to improve the bearing strength of support when the primary importance, between said first leg and second leg, be provided with the pin-and-hole that is connected of a connecting pin and corresponding connecting pin.Particularly, said first leg and second leg are the bending pipe fitting of a L-shaped opposing setting.Make the horizontal component of first leg and second leg protruding, increase the supporting stability of support in primary importance.
Relate in order to make the first L shaped leg and second leg horizontal component when the second place not take place two; Make fan structure compact more, when the said second place the L shaped horizontal component of said first leg and said second leg be interspersed in each other said housing above.
As a kind of optimal technical scheme, said support comprises the bearing that is arranged on the housing bottom surface; Said first leg and second leg are being provided with a curved part near pivot end.Setting through this curved part not only can make support its vertical component when primary importance be adjacent to back-to-back each other; Improve bearing strength, simultaneously, make first leg and second leg when the second place; The distance that its vertical component space is enough is avoided interfering with housing.
Adopt the technological scheme of the utility model, the one, make rotary blade fan have vertical and the desk dual-purpose function; The 2nd, not only make fan as desk-top use through support in the setting of the second place, the taking in and transporting of the fan of being more convenient for simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Referring to Fig. 1 and Fig. 2, a kind of rotary blade fan comprises housing 1, is arranged on motor 2 in the housing 1, is fixed on the flabellum 3 on motor 2 output shafts and is articulated in the support 4 on housing 1 bottom surface.
Housing 1 comprises front case 101 and rear case 102.On rear case 102, be provided with air-inlet grille 1021, on front case 101, be provided with blade-rotating 103 and control knob 1011.
Referring to Fig. 3, first leg 401 and second leg 402 bearing 403 through separately respectively are fixed on the bottom surface of housing 1.First leg 401 and second leg 402 are opposing setting, and its horizontal component is protruding.First leg 401 and second leg 402 are articulated on the bearing 403 through a pivot 404.First leg 401 and second leg 402 are provided with the second place of primary importance when being used to make fan be desk-top supporting when being used to make fan to be vertical supporting through this bearing 403.Is a curved part at first leg 401 and second leg 402 partly near pivot end, and first leg 401 and second leg 402 its vertical component when primary importance are pressed close to each other, can increase the intensity of supporting; And the mutual spacing that when the second place, can increase by first leg 401 and second leg, 402 vertical components leaves, and avoids interfering with front case or rear case.
Referring to Fig. 4, be provided with an elastic positioning pin structure in the end of first leg 401 and second leg, 402 curved sections.This elastic positioning pin structure comprises a locating stud 405 and a spring 406.Pivot 404 is with bearing 403 and is fixedly connected, and on pivot 404, is the locating slot 407 that is oppositely arranged.Locating stud 405 is corresponding with two locating slots 407 respectively when the primary importance and the second place.
Referring to Fig. 1, on first leg, 401 vertical components, be provided with one and connect pin-and-hole 408, on the vertical component of second leg 402, be provided with a connecting pin 409.This connecting pin 409 is corresponding and insert in the connection pin-and-hole 408 on first leg 401 when primary importance, and first leg 401 and second leg 402 are linked into an integrated entity, and is used to increase the intensity of support 4.Certainly, above-mentioned connecting pin 409 also can be arranged on first leg 401, be arranged on second leg 402 and connect pin-and-hole 408, but such setting makes support 4 when the second place, and connecting pin 409 is positioned at the front of front case 101, has influenced the outward appearance of fan.
First leg 401 and second leg 402 have a height difference; Therefore; The pivot of first leg 401 and second leg 402 also is provided with a height difference on bearing 403, make support 4 when primary importance, and first leg 401 aligns with the horizontal component of second leg 402 each other.Referring to Fig. 5, and when the second place, first leg 401 and second leg 402 intert each other above housing 1.In the present embodiment, first leg 401 is longer than the height of pivot 404 second legs 402 above all of second leg, 402, the first legs 401.This height difference also can be provided with on the contrary.
Above-described embodiment is a kind of preferred version of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that is no more than the technological scheme that claim puts down in writing, also has other variant and remodeling.
