Abstract

The utility model provides a foldable pedal-actuated skidding type bicycle, which comprises a bicycle body plate, a front bicycle fork, a steering wheel and two rear bicycle wheels. Two groups of rocker arms are installed in the middle of the bicycle body plate through a rocker arm frame, and the front ends of the rocker arms are provided with pedals. Chains fixed on rear arms of the two rocker arms are hung on two flywheels coaxially installed with the rear bicycle wheels at the rear end of the bicycle body plate, the other ends of the chains are connected with a tension spring fixed at the front end of the bicycle body plate, and the front end of the bicycle body plate and the front bicycle fork are installed in a hinged mode through a connecting frame. The foldable pedal-actuated skidding type bicycle can travel on the road by treading the pedals with two feet alternatively to pull the chains to drive the flywheels so as to drive the rear bicycle wheels installed coaxially with the flywheels to rotate. The foldable pedal-actuated skidding type bicycle can be driven to move by utilizing one foot to tread the ground, is simple in structure, nimble to use, convenient to maintain, small in occupied space after being folded and easy to place, can be used as convenient vehicle to ride instead of walk, and can be used as movable fitness equipment for users to take exercises.

Description

A kind of collapsible pedal drive wheel gliding style bicycle

Technical field

The utility model belongs to the traffic means of transport technical field, relates to a kind of gliding style bicycle of taking turns, and is specifically related to a kind of collapsible pedal drive wheel gliding style bicycle

Background technology

In the middle of daily life, bicycle has become that popular colony rides instead of walk and the ordinary traffic instrument of exercise, existing bicycle mostly drives the rotation of flywheel driving bicycle rear again with foot-operated rotating sprocket and travels, this structure of bicycle is relatively complicated, after bicycle uses a period of time, distance between sprocket wheel and the flywheel can shorten, and the chain that connects it tends to slippage, gives and brings some troubles by bike.Though and Kickboard Scooter is simply small and exquisite, need with a pin continuously scrunch ground obtain propulsive effort can be to overtake.Both lacked continuous power-handling capability, and the time one that scrunches continuously is long also very tired.

The utility model content

The purpose of this utility model provides a kind of collapsible pedal drive wheel gliding style bicycle, and its adopts wheel gliding style structure, pedal type to drive, and can fold easily again, not only lightly but also convenient, has solved the problem that existing bicycle and Kickboard Scooter exist.

The technical scheme that the utility model adopted is, a kind of collapsible pedal drive wheel gliding style bicycle, comprise body panels, car front fork, steering wheel and two back wheels of vehicle, two groups of rocking arms are installed by rocker stand in described body panels middle part; the front end of rocking arm is equipped with stretcher; chain fixing on the postbrachium of two rocking arms hangs on body panels rear end and coaxial mounted two flywheels of back wheels of vehicle, and the other end of chain is connected with the extension spring that the body panels front end is fixed.

Collapsible pedal drive wheel gliding style bicycle described in the utility model, its feature also be,

Described body panels front end and car front fork are by the hinged installation of link span.

The collapsible pedal drive wheel of the utility model gliding style bicycle, adopting the both feet exchange to trample stretcher just can spur the chain drive flywheel and drive coaxial mounted back wheels of vehicle rotation, sail in the enterprising every trade of road, also can step on surface driving with single pedal and travel, it both can be used as the vehicle and had ridden instead of walk, can be used as health and fitness facilities again and carried out physical exercise, it is simple in structure, it is dexterous convenient to use, and it is little to take up room after folding, and is convenient to put.

Description of drawings

Fig. 1 is the collapsible pedal drive wheel of a utility model gliding style bicycle structure scheme drawing;

Fig. 2 is the collapsible pedal drive wheel of a utility model gliding style bicycle folding view.

Among the figure, 1. body panels, 2. car front fork, 3. steering wheel, 4. back wheels of vehicle, 5. rocker stand, 6. rocking arm, 7. stretcher, 8. postbrachium, 9. chain, 10 flywheels, 11. extension springs, 12. link spans, 13. handlebars.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

A kind of collapsible pedal drive wheel gliding style bicycle, as shown in Figure 1, comprise body panels 1, car front fork 2, steering wheel 3 and two back wheels of vehicle 4, two groups of rocking arms 6 are installed by rocker stand 5 in described body panels 1 middle part; the front end of rocking arm 6 is equipped with stretcher 7; chain 9 fixing on the postbrachium 8 of two rocking arms 6 hangs on body panels 1 rear end and back wheels of vehicle 4 coaxial mounted two flywheels 10, and the other end of chain 9 is connected with the extension spring 11 that body panels 1 front end is fixed.

The collapsible pedal drive wheel of the utility model gliding style bicycle, during use, the people stands in earlier on the body panels 1, hand steered handlebar 13, alternately trample on the stretcher 7 of two rocking arms, 6 front ends about again both feet being stood in respectively, alternately upwards swing of the postbrachium 8 of two rocking arms 6 about just can making, upwards the postbrachium 8 of swing drives chain 9 upward movements that are fixed on the rear end, in the time of chain 9 upward movements, can haul its flywheel of hanging 10 rotates forward, two alternately coaxial mounted two back wheels of vehicle, 4 rotations of flywheel 10 drivings of rotation, after stretcher 7 is floored, will retract the stretcher 7 and the postbrachium 8 that drive rocking arm 6 simultaneously and reset being connected chain 9 with the fixing extension spring 11 of body panels 1 front end.Bipod to about alternately trampling of not stopping of the stretcher 7 of two rocking arms 6, order about two chains, 9 bonded assembly flywheels 10 alternately rotation drive the rotation that coaxial mounted back wheels of vehicle 4 does not stop, sail in the enterprising every trade of road.The utility model also can adopt single pedal to step on the driving car and travel, and wherein a pin steps down on the body panels 1, and another pedal is stepped on the road surface, just can advance forward by car.

The collapsible pedal drive of the utility model is taken turns the gliding style bicycle, and it is simple in structure, it is dexterous convenient to use, both having can be used as the vehicle rides instead of walk, can be used as health and fitness facilities again and carry out physical exercise, its body panels 1 front end and car front fork 2 are by link span 12 hinged installations, can conveniently fold, it is little to take up room after folding, and is convenient to put.

Above-mentioned embodiment is an example of the present utility model; not to be used for limiting enforcement of the present utility model and interest field; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
