Abstract
The utility model relates to a lever labor-saving bicycle. A left petal and a right petal are installed on the lower end of the middle portion of a bicycle body, the petals are installed on the front ends of two long strip-shaped levers, and each lever penetrates through a worm wheel and is divided into a front long section and a rear short section through the worm wheel. Each worm wheel is fixed on a center shaft, each center shaft is connected with a connection rod at one end of each worm wheel and can rotate, the center shafts are connected with a chain wheel through concentric shafts, and the chain wheel is connected with a chain in a sleeved mode and is connected with a rear wheel shaft through the chain. The lever labor-saving bicycle utilizes the lever principle, small force is required to be exerted on the petals to complete the whole process, a rider can save labor, and distance and time of long-distance riding are improved. The lever labor-saving bicycle has the advantages of being simple and practical in structure, convenient and flexible to use, labor-saving and environment-friendly, and is particularly suitable for long-distance riding of old people.
Description
Technical field
The utility model belongs to environment-friendly type traffic means of transport technical field, and relating to a kind of only need not to move in a circle by pedal needs both feet pedal up and down the bicycle of the lever force-saving that power can move.
Background technology
Bicycle is a kind of very easily vehicle, usually uses bicycle both to be conducive to the energy protection of the environment, again can be by taking exercises to improve people's fitness.But use existing bicycle overlong time, cause easily the bicyclist to take off power, can't be applicable to long-distance riding, be unfavorable for that especially the elderly uses.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provides a kind of bicycle with lever force-saving of practical, laborsaving characteristics of environmental protection.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of bicycle of lever force-saving, comprise vehicle body, be provided with left and right sides pedal in lower end, vehicle body middle part, described pedal is placed in the front end of two strip shape levers, lever passes turbine and has been divided into front long section and rear short section by turbine, the connecting rod that described turbine is fixed on turbine one end connects on the axis that can rotate, and described axis is connected with sprocket wheel by concentric shafts, is socketed with chain on the sprocket wheel and links to each other with hind axle by chain.
Described axis outer cover has the fixed cover of a circle, fixed cover by horizontal fixed link be welded on vehicle vertical cube with it to vertical rod fix.
The end of described lever and horizontal fixed link are movably connected.
The beneficial effects of the utility model are: utilize lever principle, only need to apply less power to pedal can finish whole process, make the bicyclist can save muscle power, improve long-distance distance of riding and time, have the characteristics of simple and practical, easy to use and flexible, laborsaving environmental protection, be very suitable for the long-distance use of riding of the elderly.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-pedal, 2-lever, 3-turbine, 4-fixed link, 5-axis, 6-sprocket wheel, 7-fixed cover, 8-hind axle.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of bicycle of lever force-saving, comprise vehicle body, be provided with left and right sides pedal 1 in lower end, vehicle body middle part, described pedal 1 is placed in the front end of two strip shape levers 2, lever 2 passes turbine 3 and has been divided into front long section and rear short section by turbine 3, thereby bicyclist's both feet make lever 2 follow together motion by pedal 1 being applied downward power, because the end of lever 2 and horizontal fixed link 4 are movably connected, applied force can make lever 2 front end up-and-down movements and drive turbine 3 motions, because being fixed on the connecting rod of turbine 3 one ends, turbine 3 connects on the axis 5 that can rotate, when turbine 3 motion, can drive axis 5 rotates, thereby axis 5 is moved together by the sprocket wheel 6 that concentric shafts connects, the fixed cover 7 that a circle is arranged in described axis 5 outer cover, fixed cover 7 by horizontal fixed link 4 be welded on vehicle vertical cube with it to vertical rod fix, be socketed with chain on the sprocket wheel 6 and link to each other with hind axle 8 by chain, sprocket wheel 6 is by 8 motions of chain-driving hind axle, thereby so that automatic vehicle travel forward.
The utility model utilizes lever principle, only need to apply less power to pedal can finish whole process, makes bicyclist's energy laborsaving, improves long-distance distance of riding and time, have the characteristics of simple and practical, easy to use and flexible, laborsaving environmental protection, be very suitable for the long-distance use of riding of the elderly.
