Background technique
The blowing cooling system of the feature that stand fan is large as a kind of air quantity, noise is low, in the summer of sweltering heat, to room ventilation ventilation, reducing temperature of heatstroke prevention, environmental protect effect etc. has very important effect.Especially for the field that family uses, stand fan also has to place to be stablized, and safe and reliable characteristic, is therefore extensively subject to liking of people.
Along with the raising of people's living standard, there is higher requirement to the use of stand fan.Wherein, the height adjustable of stand fan is exactly intimate hope and the requirement of vast stand fan user.Adjustable for height stand fan, not only can meet basic cooling function, and can, according to concrete use height needs, the wind of blowout is farthest used by stand fan.Existing Chinese patent ZL201020541040.4 discloses a kind of adjusting nut to regulate the technological scheme of height, although adjusting nut can regulate height, but because the fan body of stand fan is heavier, adjusting nut is regulated to need very large power with hand, and fan body easily rocks when regulating, stability and poor reliability.Chinese patent ZL201420600462.2 and ZL201220050762.9 discloses and uses clamping bolt to realize Height Adjustable stand fan, they all also exist shortcoming: when using clamping bolt to regulate, not only there will be fan body easily to rock, and clamping bolt realize in electrodeless position regulation performance poor, even used of a specified duration and there will be stripped thread phenomenon, the life-span is short.
Summary of the invention
The utility model, in order to overcome existing deficiency, proposes a kind of foot-operated height-regulating mechanism of stand fan.
The utility model is achieved through the following technical solutions:
A foot-operated height-regulating mechanism for stand fan, by chassis, driven wheel of differential, driving bevel gear bearing I, ratchet, foot-operated live axle, pedal, key I, ratchet, axle sleeve I, key II, chassis cover, heighten dagger, heighten axle, key III, shaft sleeve II, bearing II form; The outer ring of described bearing II is arranged in the groove on chassis, and inner ring is connected with the lower end heightening axle; Described heightening on axle is provided with shaft sleeve II, driven wheel of differential, key III, and shaft sleeve II is arranged between bearing II and driven wheel of differential; Heighten axle upper end and heighten dagger and be threaded connection; The driving bevel gear engaged with described driven wheel of differential is arranged on foot-operated live axle by key II, described foot-operated live axle is provided with bearing I, axle sleeve I, ratchet, rides and is connected by key I between live axle with ratchet; Ratchet is hinged on chassis cover together with pedal one end, and the middle part of pedal is hinged on foot-operated live axle; Described chassis cover is arranged on chassis by screw thread.
As preferably, described bearing I uses deep groove ball bearing, and bearing II uses thrust ball bearing.
As preferably, heightening axle with heightening the screw thread that dagger is connected is trapezoidal motion thread.
Compared with prior art, the beneficial effects of the utility model are: compared with traditional adjustment in use bolt or tightening nut, foot-operated height-regulating mechanism of the present utility model is while realization regulates stand fan fan body height, user operates simple and convenient, time saving and energy saving, safety is firm, only need use pin gently firmly pushes pedals just can regulate the height of stand fan fan body, and, by the principle of screw-driven, can realize the adjustment of arbitrary position in fan body stroke range, the thread intensity of trapezoidal thread is high, service time is long, and the life-span is secure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
Embodiment
The foot-operated height-regulating mechanism of a kind of stand fan of the utility model, its function realizes the time saving and energy saving height reliablely and stablely regulating again stand fan fan body, in order to the principle and heighten method heightened of the present utility model is more clearly described, be described further in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the foot-operated height-regulating mechanism of a kind of stand fan of the utility model, by chassis 1, driven wheel of differential 2, drive bevel gear 3, bearing I 4, ratchet 5, foot-operated live axle 6, pedal 7, key I 8, ratchet 9, axle sleeve I 10, key II 11, chassis cover 12, heighten dagger 13, heighten axle 14, key III 15, shaft sleeve II 16, bearing II 17 form, the engagement driving of two bevel gears the rotation of foot-operated live axle 6 is converted to heighten axle 14 heighten rotation, heighten dagger 13 and heighten by screw-driven between axle 14, heightening of real stand fan fan body.Ratchet 5 and ratchet 9 can realize the rising of stand fan fan body and the effect of decline.Its concrete connection, being described as follows of installation:
The outer ring of described bearing II 17 is arranged in the groove on chassis 1, and inner ring is connected with the lower end heightening axle 14; Described heightening on axle 14 is provided with shaft sleeve II 16, driven wheel of differential 2, key III 15, and shaft sleeve II 16 is arranged between bearing II 17 and driven wheel of differential 2; Heighten axle 14 upper end and heighten dagger 13 and be threaded connection; The driving bevel gear 3 engaged with described driven wheel of differential 2 is arranged on foot-operated live axle 6 by key II 11, described foot-operated live axle 6 is provided with bearing I 4, axle sleeve I 10, ratchet 5, and the foot-operated key I 8 that passes through between live axle 6 with ratchet 5 is connected; Ratchet 9 is hinged on chassis cover 12 together with pedal 7 one end, and the middle part of pedal is hinged on foot-operated live axle 6; Described chassis cover 12 is arranged on chassis 1 by screw thread.Described bearing I 4 uses deep groove ball bearing, and bearing II 17 uses thrust ball bearing.Heightening axle 14 with heightening the screw thread that dagger 13 is connected is trapezoidal motion thread.
The working principle of the foot-operated height-regulating mechanism of a kind of stand fan of the utility model is simple, realizes the simple operation of its height regulating function.Its working principle is illustrated below in conjunction with accompanying drawing.
When needing the fan body of stand fan to heighten, foot pedals 7, because pedal 7 and ratchet 9 are hinged, ratchet 9 is stirred ratchet 5 and is rotated, the foot-operated live axle 6 be connected by key I 8 with ratchet 5 is rotated, thus the driving bevel gear 3 be connected by key II 11 with foot-operated live axle 6 is rotated, drive the rotation of bevel gear 3 that the driven wheel of differential 2 engaged with it can be driven to rotate, thus the axle 14 of heightening be connected by key III 15 with driven wheel of differential 2 is rotated, directly that trapezoidal thread is connected owing to heightening axle 14 with heightening dagger 13, so, finally make to heighten dagger 13 to raise, complete the function being heightened stand fan fan body by foot pedals 7.When needs reduce stand fan fan body time, pin oppositely steps on plate 7, and owing to having installed ratchet 9 and ratchet 5, in like manner, its process regulated and principle are with raising the identical of fan body.
Foot-operated height-regulating mechanism of the present utility model is while realization regulates stand fan fan body height, user operates simple and convenient, time saving and energy saving, safety is firm, only need use pin gently firmly pushes pedals just can regulate the height of stand fan fan body, and, by the principle of screw-driven, can realize the adjustment of arbitrary position in fan body stroke range, the thread intensity of trapezoidal thread is high, service time is long, and the life-span is secure.
