The feature of technique scheme and further improvement:
Described adjustment plate and flabellum dish are arranged in rotating shaft by mounting hole, are provided with axial tangent plane on the circumferential surface of rotating shaft front end, and in the mounting hole of adjustment plate and flabellum dish and rotating shaft, tangent plane part matches.
Described worm gear connecting rod is less than helical spring maximum compression length along the axial stroke of rotating shaft.
In described flabellum dish and adjustment plate, be provided with for the draw-in groove against helical spring end.
The beneficial effects of the utility model are, by the root of flabellum is hinged on flabellum dish, flabellum regulating lever is flexibly connected with adjustment plate, back and forth affect the distance between worm gear connecting rod dealing polyphony joint adjustment plate and flabellum dish by the worm gear of rotation again, and then the angle of adjustment flabellum and its plane of rotation, thereby blowing scope radially constantly the changing at flabellum rotating locus of facilitating electric fan.
Accompanying drawing explanation
Below by the drawings and specific embodiments, the utility model is further detailed:
Fig. 1 is the overall structure schematic diagram that a kind of scope of drying of the present utility model continues the electric fan changing;
The forward schematic diagram of flabellum and flabellum dish in Fig. 2 Fig. 1.
In above figure: 1, motor; 2, worm gear frame; 3, rotating shaft; 4, worm gear; 5, tubular worm screw; 6, worm gear connecting rod; 7, push-plate; 8, thrust-bearing; 9, adjustment plate; 10, flabellum; 11, flabellum connecting rod; 12, helical spring; 13, flabellum dish; 14, stop nut.
Embodiment
With reference to figure 1 and Fig. 2, a kind of scope of drying of the present utility model continues the electric fan changing, its rotating shaft (3) is stretched out from motor (1) front end, be fixed with flabellum dish (13) at rotating shaft (3) front end, at rotating shaft (3) end, stop nut (14) is installed, on flabellum dish (13) circumferential surface, is evenly distributed with multiple flabellums (10).Specifically, at rotating shaft (3) middle part, fixed cover is equipped with tubular worm screw (5), is set with and is provided with thrust-bearing (8), adjustment plate (9) and helical spring (12) forward successively at rotating shaft (3) front end.Be set with push-plate (7) at thrust-bearing (8) near motor (1) one side.In motor (1) front end shell, be fixed with worm gear frame (2), worm gear (4) is installed on worm gear frame (2).
The root of each flabellum (10) is articulated with the circumferential surface place of flabellum dish (13).Each flabellum (10) is flexibly connected with adjustment plate (9) by a corresponding flabellum connecting rod (11).Helical spring (12) is resisted against between flabellum dish (13) and adjustment plate (9).Between the side of the circumferential surface of push-plate (7) and worm gear (4), be provided with the worm gear connecting rod (6) of flexible connection, tubular worm screw (5) engages with worm gear (4).
In order to allow blowing scope of the present utility model continue the electric fan trouble-free operation changing, note also that, rotating shaft (3) front end is provided with axial tangent plane, and the tangent plane part in mounting hole and the rotating shaft (3) of adjustment plate (9) and flabellum dish (13) matches.Like this, push-plate (7), along with thrust-bearing (8) phase countershaft (3) rotates, can also slide along rotating shaft (3).Adjustment plate (9) and flabellum dish (13) can only slide along rotating shaft (3), must synchronize with rotating shaft (3) rotation.
In the time that the rotating shaft (3) of motor (1) is rotated, the tubular worm screw (5) of the upper fixing suit of rotating shaft (3) drives worm gear (4) slow circumvolve, worm gear (4) affects worm gear connecting rod (6) to move back and forth, worm gear connecting rod (6) reciprocating push-plate (7), thrust-bearing (8) and adjustment plate (9), adjustment plate (9) affects flabellum connection-rod (15) motion in moving back and forth vertically, make all flabellums (10) reciprocally swinging on flabellum dish (13), swinging center is positioned at the hinged place of each flabellum (10) root and flabellum dish (13).In this process, flabellum (10) constantly changes with the angle of plane of rotation, causes electric fan blowing scope also constantly to change.Helical spring (12) between adjustment plate (9) and flabellum dish (13) has played reset adjustment plate (9) and has prevented the effect of flabellum dish (13) axial float.In order to prevent the radial-play of helical spring (12), in flabellum dish (13) and adjustment plate (9), be provided with for the draw-in groove against helical spring (12) end.
In order to reduce the pressure on worm gear connecting rod (6), worm gear connecting rod (6) is less than the maximum compression length of helical spring (12) along the axial stroke of rotating shaft (3).
