Abstract
The utility model discloses a running bicycle based on crank rocker mechanisms. The running bicycle comprises a body, a chainwheel, a middle shaft arranged in the middle of the body, a rear shaft arranged on the rear portion of the body and two sets of the crank rocker mechanisms used for driving the body to move. Each crank rocker mechanism comprises a crank, a connecting rod and a rocker, wherein the crank, the connecting rod and the rocker are sequentially and rotatably connected end to end. The two sets of the crank rocker mechanisms are arranged on the two sides of the body respectively, one end of each crank is rotatably connected with the middle shaft, the cranks are fixedly connected with the chainwheel, the chainwheel is rotatably connected with the middle shaft, one end of each rocker is rotatably connected with the rear shaft, and each connecting rod is provided with a pedal. According to the running bicycle based on the crank rocker mechanisms, the crank rocker mechanisms are used on a bicycle so that the running pace of a person can be simulated in a realistic mode, ankles are not prone to being hurt, and a running machine and the bicycle are well integrated. The running bicycle is of a pure mechanical structure, and is simple in structure, low in manufacturing cost and environmentally friendly.
Description
Technical field
The utility model relates to a kind of bicycle, is specifically related to a kind of crippled mode that utilizes and realizes the bicycle for double march body building based on quadric linkage that drives bicycle to advance.
Background technology
At present, bicycle for double march body building is to be combined by traditional treadmill belt conveyor and bicycle, tramples belt conveyor by the people and drives conveyer belt, and further drive wheel movement, realizes the advancement function of bicycle.The shortcoming of this structure is that volume is large, and belt conveyor tilts to make ankle not only to be subject to bearing capacity upwards, and is subject to power backward, can't simulate people's running paces fully, easily pulls ankle.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the bicycle for double march body building based on quadric linkage of foot's track when more approaching the people when the utility model provides a kind of the use and running.
Technical scheme: for achieving the above object, bicycle for double march body building based on quadric linkage of the present utility model, comprise body, fluted disc, be arranged on the axis at body middle part, the rear axle that is arranged on rear body and two groups of quadric linkages for driving body to move; Described quadric linkage comprises crank, connecting rod and rocking bar; Described crank, connecting rod and rocking bar join end to end successively and are rotationally connected, two suite handle rocker mechanisms are arranged in the both sides of body, and crank one end and axis are rotationally connected, and crank and fluted disc are connected, fluted disc and axis are rotationally connected, and an end and the rear axle of rocking bar are rotationally connected; Be equipped with stretcher on described connecting rod.
As preferably, described connecting rod is "the" shape.
As preferably, two cranks become 80 degree.
Beneficial effect: the bicycle for double march body building based on quadric linkage of the present utility model, by quadric linkage is applied to bicycle, can simulate realistically people's running paces, be not easy to pull ankle, better treadmill and bicycle are combined together, for pure physical construction, simple in structure, low cost of manufacture, environmental protection.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the bicycle for double march body building based on quadric linkage of the present utility model, comprise body, fluted disc, be arranged on the axis at body middle part, the rear axle that is arranged on rear body and two groups of quadric linkages for driving body to move; Described quadric linkage comprises crank 4, connecting rod 1 and rocking bar 3; Described crank 4, connecting rod 1 and rocking bar 3 join end to end successively and are rotationally connected, two suite handle rocker mechanisms are arranged in the both sides of body, and crank 4 one ends and axis are rotationally connected, and crank 4 and fluted disc are connected, fluted disc and axis are rotationally connected, and an end and the rear axle of rocking bar 3 are rotationally connected; Be equipped with stretcher 2 on described connecting rod 1.
In the present embodiment, described connecting rod 1 is "the" shape.4 one-tenth 180 degree of two cranks.
The utility model is mainly to utilize quadric linkage to be transformed the driver train of bicycle.When trampling stretcher 2, stretcher 2 can move by drivening rod 1, and connecting rod 1 drives crank 4 and rotates around axis, and fluted disc will rotate and drive trailing wheel by chain gear with crank 4 and rotate around rear axle, thereby drives bicycle to advance.
Bicycle for double march body building based on quadric linkage of the present utility model, by quadric linkage is applied to bicycle, can simulate realistically people's running paces, be not easy to pull ankle, better treadmill and bicycle are combined together, for pure physical construction, simple in structure, low cost of manufacture, environmental protection.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
