Description
Technical field
The utility model relates to a kind of fan, particularly foot-operated fan.
Background technique
Tradition enjoys the cool instrument often for hand-held fan, electric fan and air-conditioning.Electric fan and air-conditioning rely on electric power thus supplied completely, just cannot work when power-off in summer.In the event of a power failure, usual people are enjoyed the cool by hand-held fan, and the frequency of okperation of hand is higher, and continuous firing wind-force is little, and user uses for a long time and easily produces arm fatigue and weak effect of enjoying the cool.
Summary of the invention
For solving the problem of enjoying the cool when having a power failure summer, provide a kind of foot-operated fan, this fan structure advantages of simple, easy to use, compare Hand swing fan and more efficient wind-force can be provided.
For achieving the above object, the utility model is by the following technical solutions:
Foot-operated fan, comprise support, wood clapper, fan blade, wood clapper is arranged on the first main shaft of support, clip springs is fixed with between wood clapper and support, clip springs is wound around end and is enclosed within the fixing rod of support, the side of wood clapper is provided with slide bar, is fixed the slide opening being provided with the tooth bar on support and coordinating with foot treadle slide bar by slide block sliding groove structure, and slide bar is through slide opening; Spur gear is connected to support by the second main shaft, and straight-tooth wheel and rack coordinates, and the other end of the second main shaft and spur gear are coaxially installed with the first bevel gear, and bevel gear is connected by unilateral bearing with the second main shaft; The top of support is fixed with fan blade by the first rotating shaft, and the rear end of rotating shaft is fixed with the second bevel gear; Second rotating shaft is vertically rack-mount, and the upper/lower terminal of the second rotating shaft is provided with bevel gear, and the bevel gear of upper end coordinates with the second bevel gear of fan blade rotating shaft, and the bevel gear of lower end coordinates with the first bevel gear.
Above-mentioned foot-operated fan, the support base plate below wood clapper offers shrinkage pool.
Clip springs is wound around end and is enclosed within the fixing rod of support, this one end and support are conflicted, clip springs follows foot treadle after holder orientation compression, the winding end of clip springs produces distortion and produces tension force thus, the opening end of clip springs is against the back side of foot treadle, tension force acts on the foot treadle back side by foot treadle by the back side forwardly, i.e. the side of human foot, releases and resets.
The shrinkage pool that support base plate is offered below wood clapper, agrees with the tracks of foot treadle, and foot treadle can freely be stirred, and also can reduce the height of support simultaneously.
Because the strength of leg is comparatively large, is worked by pedal drive fan blade, make to enjoy the cool during power-off leicht fallen D/A, be particularly useful for the student, the teacher that lie prostrate first desk work.

Be labeled as in figure: 1 fan blade, 11 fan blade rotating shafts, 12 are fixed on the second bevel gear in fan blade rotating shaft, 2 fan blade cases, 3 vertical rods, 31 bevel gears being fixed on the second rotating shaft upper end, 32 second rotating shafts, 33 bevel gears being fixed on the second rotating shaft lower end, 4 base outer covers, 41 supports, 42 first main shafts, 43 second main shafts, 44 spur gears, 45 unilateral bearings, 46 tooth bars, 47 first bevel gears, the chute coordinated with tooth bar on 48 base plates, 5 base plate perforates, 6 base plates, 7 pedals, the slide bar of 71 pedal sides, slide opening on 72 tooth bars, 73 clip springs, 74 for the fixing rod of sheathed clip springs.
Embodiment
Embodiment one
With reference to accompanying drawing, foot-operated fan, comprise support 6, wood clapper 7, fan blade 1, wood clapper is arranged on the first main shaft 42 of support, be fixed with clip springs 73 between wood clapper and support, clip springs is wound around end and is enclosed within the fixing rod 74 of support, and the side of wood clapper is provided with slide bar 71, fixed by slide block sliding groove structure and be provided with the tooth bar 46 on support the slide opening 72 coordinated with foot treadle slide bar, slide bar is through slide opening; Spur gear 44 is connected to support by the second main shaft 43, and straight-tooth wheel and rack coordinates, and the other end of the second main shaft and spur gear are coaxially installed with the first bevel gear 47, and bevel gear is connected by unilateral bearing 45 with the second main shaft; The top of support is fixed with fan blade 1 by the first rotating shaft 11, and the rear end of rotating shaft is fixed with the second bevel gear 12; Second rotating shaft 32 is vertically rack-mount, the upper/lower terminal of the second rotating shaft is provided with bevel gear 31,33, the bevel gear 31 of upper end coordinates with the second bevel gear of fan blade rotating shaft, and the bevel gear 33 of lower end coordinates with the first bevel gear, and support base plate offers shrinkage pool 5 below wood clapper.
Pass through foot pedal, seesawed along the chute 48 of frame bottom by the slide bar of pedal side, sliding groove structure band carry-over bar, rack drives spur gear and the motion of coaxial bevel gear, by the first bevel gear and the upper and lower end bevel gear of the second rotating shaft of vertically installing, the second bevel gear of fan blade rear end, transfer the motion to fan blade, fan blade is rotated, and it is distinguished and admirable that generation is enjoyed the cool.
Unclamp pedal, pedal is resetted by the tension force compressing rear generation by clip springs, pedal reset strap carry-over bar moves to health direction, spur gear also reverses simultaneously, because the second main shaft as spur gear rotating shaft is connected by unilateral bearing with the first bevel gear, the reversing of spur gear can not make the first bevel gear that phenomenon also occurs to reverse.
Due to the effect of unilateral bearing, no matter thus pedal is forward or backward, export unidirectional movement to fan blade all the time, make fan blade can keep one-way rotation always.In any position of transmission, unilateral bearing is installed and can produces identical effect.
