Abstract
The utility model relates to a double-chain wheel speed increasing folding bicycle, which solves the problems of larger volume, no folding functions, inconvenience for storage, inconvenience for portability, grade climbing exertion, low speed and more labor intensity. The utility model is characterized in that a locking device (7) which can be used for the inflection of the main rod (6) of a handle bar is arranged between a main rod (6) of a handle bar and a bicycle frame (12); the tail end of the bicycle frame (12) is provided with a locking device (29) or (21) and a locking device (19) which can be used for the inflection of a saddle frame (17) and a saddle supporting frame (18) behind a centre shaft (28); a locking device (19) is arranged between the saddle frame (17) and a saddle (20) to cause a bicycle body to be folded; a double-chain fly wheel which can be used for improving the speed of the bicycle between a main fly wheel (13) and a small fly wheel (23) which is used for driving a bicycle rear wheel to move to reduce labor intensity.
Description
The utility model belongs to the technical field that engineering goods are made, and is specifically related to a kind of double-stranded wheel speedup folding bicycle.
Present bicycle, carriage for children are single flywheel, the reinforcing of strand bar mostly, exist volume bigger, and unfolded function, floor area are big, deposit inconvenience, carry inconvenience, exercise the climbing effort, slow-footed defective.
The purpose of this utility model is at above deficiency, provides a kind of round trip flight wheel afterburning, alleviate human body labour intensity greatly, and road speed is fast, can fold, and volume is little, deposits conveniently, two strands wheel speedup folding bicycle easy to carry.
Content of the present utility model is the locking (7) that is provided with a mobile jib (6) inflection of can buying car in installments between two strands wheel speedup folding bicycle handlebar mobile jib (6) and vehicle frame (12); Between the small flywheel (23) of two strands wheel speedup folding bicycle primary flywheel (13) and the motion of drive back wheels of vehicle, be provided with a double-stranded flywheel (15); At two strands wheel speedup folding bicycle axis (28) afterwards, vehicle frame (12) tail end setting can buy car in installments locking (29) or (21) of seat (17), car use of revenue to finance expense frame (18) inflection are provided with locking (19) between car seat (17) and car seat (20); Vehicle frame (12) is straight formula horizontal bar shape.
Advantage of the present utility model is: the one, and the handlebar of vehicle body upper portion, handlebar mobile jib, and car seat, car use of revenue to finance expense frame, car sit and can all fold, and dwindles the car body volume, reduces floor area, is convenient to deposit, easy to carry; The 2nd, the vehicle body running part has been set up a double-stranded flywheel, has improved road speed, has alleviated human body labour intensity.
