The utility model relates to a kind of bicycle of the usefulness of riding instead of walk, particularly a kind of convenient folding bicycle.
(2) background technology
Bicycle is our the most frequently used vehicle, but bicycle exists certain defective when storing, bicycle deposits for convenience, folding bicycle has appearred, but existing folding bicycle mostly is the chain gear of axis chain wheel, folder function just is subjected to the restriction of axis chain wheel when depositing, and folds up comparatively loaded down with trivial detailsly, influences people's work efficiency.
(3) summary of the invention
The utility model provides a kind of convenient folding bicycle that adopts cord drive, is convenient to fold in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of convenient folding bicycle, comprise front-wheel, trailing wheel, front-wheel is connected with turning to front vehicle frame, and trailing wheel is connected with the back vehicle frame, it is characterized in that: described front vehicle frame is connected with the vehicle seat axle that top is equipped with vehicle seat, and the vehicle seat outer shaft sleeve has the axle that revolves that is connected with the back vehicle frame; A described posterior face of revolving is equipped with the swing handle of fixing the back vehicle frame; Described rear axis both sides are equipped with flywheel, and flywheel is connected with the fixed pulley that is arranged on vehicle frame both sides, back by rope respectively; Described rear axis flywheel sidepiece is provided with crank shell forward, and crank shell afterbody is provided with the power that the connects fixed pulley stay cord that resets; Described crank shell end joint connection has stretcher; The sliding extension bar that described crank shell is an interior smooth; Described vehicle seat axle side surface connects revolves the knob that the axle place is provided with the lifting of adjusting vehicle seat.
The beneficial effects of the utility model are: the convenient folding bicycle of this utility model simple in structure, chain wheel, chain gear have been saved, with the carrier of rope as transferring power, the circular movement of bicycle crank is transformed to up-and-down movement, and the power of generation bicycle running, scrunch up and down and save labour laborsavingly, reach speed change, be convenient to when depositing fold by telescoping crank.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model;
Among the figure, 1 front-wheel, 2 trailing wheels, 3 front vehicle frame, 4 back vehicle frames, 5 vehicle seats, 6 vehicle seat axles, 7 revolve axle, 8 swing handles, 9 flywheels, 10 ropes, 11 fixed pulleys, 12 crank shells, 13 stretchers, 14 knobs, the 15 power stay cord that resets.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises front-wheel 1, trailing wheel 2, front-wheel 1 is connected with turning to front vehicle frame 3, trailing wheel 2 is connected with back vehicle frame 4, and it is characterized in that: described front vehicle frame 3 is connected with the vehicle seat axle 6 that top is equipped with vehicle seat 5, vehicle seat axle 6 is outer be be connected with back vehicle frame 4 revolve axle 7; Described axle 7 posterior face of revolving are equipped with the swing handle 8 of fixing back vehicle frame 4; Both sides, described trailing wheel 2 axle center are equipped with flywheel 9, and flywheel 9 is connected with the fixed pulley 11 that is arranged on vehicle frame 4 both sides, back by rope 10 respectively; Described trailing wheel 2 axle center flywheels 9 sidepieces are provided with crank shell 12 forward, and crank shell 12 afterbodys are provided with the power that connects fixed pulley 11 stay cord 15 that resets; Described crank shell 12 end joint connections have stretcher 13; Described crank shell 12 is the sliding extension bar of interior smooth; Described vehicle seat axle 6 side surface connect revolves the knob 14 that axle 7 places are provided with 5 liftings of adjusting vehicle seat.
Adopt convenient folding bicycle of the present utility model, the time standby pin that travels scrunches stretcher 13 downwards, crank shell 12 will rotate by the power stay cord 15 pulling fixed pulleys 11 that reset, fixed pulley 11 drives the rotation of flywheel 9 and trailing wheel 2 by the biography band effect of rope 10, trailing wheel 2 has moved ahead with regard to driving whole bicycle like this, the power stay cord 15 that resets of this moment has set back, during flywheel 9 reversings, break away from trailing wheel 2 axle center, stretcher 13 alternating actions of both sides like this, trailing wheel 2 is travelled forward, can be for prevent that rope 10 from skidding in the groove of flywheel 9 with rope more than 10 around several circles; Deposit folding the time, swing handle 8 can be backed out, will back vehicle frame 4 revolve and turn 90 degrees revolving axle 7 places, front vehicle frame is revolved turn 90 degrees then, so just bicycle folding can have been got up, then with vehicle seat 5 whereabouts, fold simple and conveniently, operating process be simple.
