Abstract

The utility model discloses a directly pedaling type bicycle, which can be vertically pedaled from top to bottom. A pedal cranks of a common bicycle is cancelled; an upper cross rod and a pedal frame are fixed on a bicycle frame; a rotary drum witch can rotate is arranged on the upper cross rod; a chain wheel is fixed on the rotary drum; two pedals are arranged on a slide groove of the pedal frame; a lower cross rod is fixed between the lower end of the bicycle frame and the pedal frame; a chain wheel and a bevel gear are arranged on the lower cross rod; two flywheels are fixed on the rotary drum of a back wheel shaft of the bicycle. The utility model can always keep obtaining maximum moment under the action of same force, so that the useful work of manpower can be substantially increased, and the degree of fatigue of people can be lighted.

Description

Directly step on the formula bicycle

The utility model relates to a kind of vertical up and down foot-operated formula of directly stepping on bicycle, belongs to the bicycle field.

At present, bicycle of the prior art generally all is the swinging pin, bicycle, the shortcoming of this swinging bicycle is: because moment constantly changes when foot-operated, make the white waste certainly of part manpower do many idle works, can not give full play to manpower effectiveness, thereby make the people feel tired easily when using.

The purpose of this utility model is: a kind of formula of directly the stepping on bicycle that can give full play to manpower effectiveness, reduce people's fatigue is provided.

The utility model is to constitute like this: it adopts bicycle rack of the prior art (1), wheel (2), handlebar (3), car front fork (4), seat (5), cancelling stepping on of former bicycle turns, on vehicle frame (1), be fixed with cross tube (6) and running-board bracket (10) then, rotating rotating cylinder (7) is housed on cross tube (6), on rotating cylinder (7), be fixed with sprocket wheel (8) and (9), there is chute (11) two straight-bar sides at running-board bracket (10), two stretchers (16) are contained in chute (11) lining of running-board bracket (10) two sides respectively, the two ends of sheer pole (12) are separately fixed on vehicle frame (1) and the running-board bracket (10), sprocket wheel (13) and bevel gear (14) are contained on the sheer pole (12), and sprocket wheel (13) and bevel gear (14) are fixed together to go up at sheer pole (12) and rotate, chain (15) is enclosed within on the sprocket wheel (9) and two ends are separately fixed on two stretchers (16), chain (17) is enclosed within on sprocket wheel (8) and (13), bevel gear (18), (19) be contained on the axis of vehicle frame (1) and and mesh with bevel gear (14), in bevel gear (18), (19) be fixed with a chain sprocket (20) and (21) on the side end face respectively, two ends are fixed with flywheel (22) and (23) respectively on the bicycle rear shaft rotating cylinder, chain (24) is enclosed within on chain sprocket (20) and the flywheel (22), and chain (25) is enclosed within on chain sprocket (21) and the flywheel (23).

The utility model compared with prior art, owing to adopt the formula of directly stepping on, the power that the people rides remains vertical with its acting force arm, so just under the situation of identical power, obtained maximum moment, thereby improved the useful work that manpower is done fully, reduced people's degree of fatigue thereby reduced the idle work that manpower does; The utility model also has simple in structure, advantage such as the accepted standard part is more thereby cost of manufacture is lower in addition.During use, the people only need be sitting on the seat (5), goes up and tramples up and down with riding at pedal (16), and bicycle is advanced; When car slided, people's pin can be equally slack with riding ordinary bicycle, allows the bicycle art skating.

Accompanying drawing 1 is a surface structure scheme drawing of the present utility model; Accompanying drawing 2 is the utility model running-board bracket stack-mounted structural representation; Accompanying drawing 3 is the messenger chain structural representation after the utility model vehicle frame and wheel remove; Accompanying drawing 4 is the schematic top plan view of accompanying drawing 3.

Embodiment of the present utility model: adopt bicycle rack of the prior art (1), wheel (2), handlebar (3), car front fork (4), seat (5), the plag of stepping on of former bicycle is disappeared, on cross tube (5), load onto earlier rotating rotating cylinder (7), and on rotating cylinder (7), fix sprocket wheel (8) and (9), then cross tube (5) and running-board bracket (10) are fixed on the vehicle frame (1), two straight-bar sides at running-board bracket (10) respectively make a chute (11), two stretchers (16) are contained in chute (11) lining of running-board bracket (10) two sides respectively and enable can in chute, not drop out being free to slide in the chute, sprocket wheel (13) and bevel gear (14) are contained on the sheer pole (12), and sprocket wheel (13) and bevel gear (14) be fixed together make it and on sheer pole (12), to rotate together, two ends with sheer pole (12) are separately fixed on vehicle frame (1) and the running-board bracket (10) then, chain (15) is enclosed within sprocket wheel (9) is gone up and two ends are separately fixed on two stretchers (16), chain (17) is enclosed within on sprocket wheel (8) and (13), making bevel gear (18), (19) can on its side end face, produce a chain sprocket (20) and (21) respectively simultaneously the time, then with the bevel gear of making (18), (19) be contained on the axis of vehicle frame (1) and and mesh with bevel gear (14), the ordinary bicycle flywheel of selling on the market is all adopted in flywheel (22) and (23), and it is separately fixed at two ends on the bicycle rear shaft rotating cylinder, chain (24) is enclosed within on chain sprocket (20) and the flywheel (22), again chain (25) is enclosed within chain sprocket (21) and flywheel (23) and goes up.

Claims
