Description
Technical field
The utility model belongs to technical field of bicycles, especially a kind of safety labor-saving bicycle.
Background technology
Cycling trip be effect on environment minimum trip mode, i.e., it is energy saving, improve efficiency, reduce pollute,
Be good for one's health, take into account the trip mode of efficiency.Cycling trip is not only economical and practical, cost-effective, and can be strong
Physique is taken exercises.
The bicycle of the prior art all includes vehicle frame, the forepart installation front fork of vehicle frame, the upper end installation handlebar of front fork, front fork
Lower end front-wheel is installed by front axle, the rear portion of vehicle frame passes through rear axle and installs trailing wheel, rear axle Flywheel, the top installation of vehicle frame
Chain wheel, the both ends installation crank of axis, the outer end hinge of two cranks is fixedly mounted in vehicle seat, the middle and lower part installation axis of vehicle frame, axis
Pin pedal；Chain wheel is connected with flywheel by chain drive.The bicycle of this structure is that bicyclist is sitting on vehicle seat, and both feet are stepped on
Circumferential movement is done in two foot pedals, by crank, chain wheel, chain, flywheel trailing wheel is driven to rotate.
Both feet are stepped on the footrests, and only crank goes to the mistake that foot is firmly pedaled down in the range of 45° angle in the middle part of preceding half-turn
Useful work is just done in journey, the drawback is that, sweat low with force efficiency.In addition, ride stop when, it is necessary to get off or
One foot is stepped down on the road side in roadside.
The content of the invention
The purpose of the utility model is to overcome defects existing in the prior art, provide a kind of safety labor-saving bicycle, it
Have the advantages that it is simple in structure, ride it is laborsaving, safe and reliable.
Technical solution is used by the utility model：A kind of safety labor-saving bicycle, it includes vehicle frame, the forepart of vehicle frame
Front fork, the upper end installation handlebar of front fork are installed, front-wheel is installed in the lower end of front fork by front axle, and the rear portion of vehicle frame is installed by rear axle
Tooth is fixedly mounted in trailing wheel, Flywheel on rear axle, the top installation vehicle seat of vehicle frame, the middle lower portion installation axis of vehicle frame, axis
Crank is fixedly mounted in disk, the both ends of axis, and chain wheel is connected with flywheel by chain drive；It is characterized in that：The end of two cranks
Disk roller is installed in outside respectively, is respectively articulated with the drive rod for extending forward and being pressed on disk roller at the both ends of rear axle, before drive rod
Subordinate side connects chevron, and the lower part of chevron is hinged foot pedal by pedal shaft.
Further, 2~4 universal wheels are installed below each foot pedal.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is by scrunching two foot pedals in left and right up and down, passing through drive rod, disk roller, crank, chain wheel, chain
Bicycle walking is driven with flywheel.Circumferential movement is done with prior art bicycle both feet to compare, acting angle is big, pedals up and down
Legpower gas foot, it is firmly efficient, it saves the strength.
The utility model installs universal wheel below each foot pedal, and for foot pedal in extreme lower position, universal wheel is with regard to energy
It lands, cyclist, woth no need to scruple balance of bicycle problem, can use maximum strength to pedal when scrunching foot pedal.
The utility model ride stop when, can a triangle be formed by the universal wheel and front and back wheel that land and put down
Face stops vehicle, and bicyclist need not get off, and parking is convenient.
It is used in addition, it also is adapted for begining to learn bicycle person, is landed with regard to vehicle can be stopped, kept away by the universal wheel below foot pedal
Exempt from beginner to trip and fall, use is safer.
It is its advantages of combining bicycle and roller skate of the utility model, not only safe but also laborsaving.Thus, it is a kind of peace
Full labour-saving bicycle.
