Abstract
The utility model relates to a quantitative indication of rocking angle and adjustable device for an electric fan. The utility model is an adjustable device for a rocking angle of an electric fan. The utility model comprises a casing, a crank non-stage adjusting mechanism and a two-stage speed reducing mechanism, wherein, the second stage speed reducing mechanism is a gear speed reducing mechanism provided with a big gear, the upper end of the big gear is provided with a hollow shaft which is sheathed with a coaxial spindle, the upper end of the hollow shaft is connected with a big circular wheel, the upper end of the spindle is connected with an adjusting angle knob support block, and the big circular wheel and the adjusting angle knob support block are respectively provided with a mark. The utility model provides an adjusting angle device for a rocking electric fan having advantage of accurate angle adjustment. The adjusting angle device is provided with quantitative mark indication. The utility model is suitable for being used by all the rocking electric fans.
Description
The utility model relates to a kind of electric fan device, especially electric fan swing angle actuating device.
In the prior art, adjustable pivot angle electric fan mainly is the adjustment that realizes pivot angle by the length that changes crank in the crankrocker mechanism.Variable-length crank mechanism in the adjustable pivot angle device that has proposed at present, mainly be by adorning one group of gear under the hollow sleeve of a mandrel---rack slide adjustable crank mechanism or under adorn one group of planetary gear train adjustable crank mechanism, independently stretch out the outer knob of fan by one, twisting mandrel and hollow shaft relative displacement, drive adjustable crank mechanism and make corresponding displacement, and the length change adjustment of realization crank, and make corresponding pivot angle adjustment.But, because can't predicting the physical length that is enclosed in adjustable crank mechanism in the case outside fan, the user changes and corresponding pivot angle variation relation state, and fan casing does not have the quantitative sign of any angle modulation scale value outward, the user can only do the angle modulation of conjecture property search type with the sensation of experience separately.Obviously, based on the angle of swing of electric fan controlling mechanism of above-mentioned principle design, exist easily because of the personal factor generation departs from predetermined value, shortcoming is accurately owed in angle modulation.
The utility model purpose is to provide the angle pendulum regulating mechanism that a kind of angle modulation is accurately quick, the quantitative identifying indication is arranged.
The utility model comprises housing, crank stepless regulating mechanism and two utmost point reducing gears, wherein second level reducing gear is a reduction gears mechanism, reduction gears mechanism has a gearwheel, the gearwheel upper end is connected with hollow shaft, hollow shaft is with coaxial mandrel, the hollow shaft upper end is connected with 1 great circle wheel outside housing, the mandrel upper end is connected with 1 angle modulation knob anchor plate outside housing, great circle is taken turns and above the angle modulation knob anchor plate sign is arranged respectively, the central shaft of angle modulation knob anchor plate overlaps with the central shaft of great circle wheel, the great circle wheel has spring assembly, and spring assembly is assembled into elastic tight with angle modulation knob anchor plate and contacts.
With embodiment and accompanying drawing the utility model is described in further detail below:
Fig. 1 is the utility model embodiment's a sectional view;
Fig. 2 is embodiment's a plan view;
Fig. 3 is embodiment's an angle modulation knob anchor plate schematic representation;
Fig. 4 is embodiment's a great circle wheel and spring assembly erection drawing.
Referring to figs. 1 through Fig. 4, worm screw 13, worm gear 14, small gear, the gearwheel 15 composition two reduction gear that intermeshes, gearwheel 15 built-in limit sliding chutes 16, rack slide crank 17 are formed the adjustable crank structure with gear 18 engagements, hollow shaft 10 lower ends are connected with gearwheel 15, mandrel 12 lower ends are connected with gear 18, twisting mandrel 12 is made relative angular displacement with hollow shaft 10, and gear 18 just can drive rack slide crank 17 and make corresponding displacement in limit sliding chutes 16, forms crank length to change.The tipping of hollow shaft 10 tops has the great circles wheel 9 that stretches out outside the housing 11, is shaped on one above the great circle wheel 9 and can represents correctly that adjustable crank 0 to the ring-type pivot angle value dial 6 of the corresponding quantitatively variation relation of maximum value indicates; The tipping of mandrel 12 tops has the angle modulation knob anchor plate 4 that stretches out outside the housing 11, be shaped on one on the angle modulation knob anchor plate 4 and can represent correctly that the contraposition initial point 5 of sample detecting and angle modulation relation indicates, when adjustable crank is positioned at 0 value, " 0 " value on contraposition initial point 5 on the angle modulation knob anchor plate 4 and the great circle wheel 9 on the pivot angle dial 6 is an assembling, thereby forms complete fan pivot angle sample detecting device and the quantitative explicit identification device of the pivot angle number of degrees of a cover.There is spring assembly 8 in tangible holes 3 in the great circle wheel 9 in the shape hole 3, spring assembly 8 is assembled into elastic tight with concavo-convex body 7 on the angle modulation knob anchor plate 4 and contacts.Twisting angle modulation knob anchor plate 4 can force elastic device 8 retractions on the one hand and make slide displacement with great circle wheel 9, drives mandrel 12 and gear 18 concentric rotations on the other hand simultaneously, drives rack slide crank 17 and does corresponding displacement; Discharge angle modulation knob anchor plate 4, torsional moment disappears, the elastic tight contact friction force that spring assembly 8 and concavo-convex body 7 form, again angle modulation knob anchor plate 4 and great circle being taken turns 9 tightenings is one, mandrel 12, the adjustable crank mechanism of hollow shaft 10 and lower end thereof also tightening simultaneously is an one, shakes the head so electric fan is just put fixed pivot angle scale value again by contraposition initial point 5 on the angle modulation knob anchor plate 4.
The utility model provides the angle pendulum regulating mechanism that a kind of angle modulation is accurately quick, the quantitative identifying indication is arranged for the electric fan of shaking the head, the angle modulation knob that the user need only twist on the electric fan head-shield housing arrives required pivot angle scale value, electric fan just can carry out oscillation angle by setting value exactly, user's conjecture search procedure and angle modulation deviation have been exempted, be the optimal selection of oscillating fan, it suits to use in all electric fans of shaking the head.
