Body-building scooter
Technical field
The utility model relates to a kind of body-building scooter.
Technical background
Kickboard Scooter not only can be used as walking-replacing tool, and is widely used in amusement, motion, body-building.Existing Kickboard Scooter according to using method and constructional feature, mainly can be divided three classes:
(1) two skidding wooden handcart.The user will make Kickboard Scooter obtain the power that advances with single pedal ground every now and then, this Kickboard Scooter mainly for 4-12 year the entertainment for children sport and body-building use, use this Kickboard Scooter that training children's balanced capacity is had certain effect, owing to will make Kickboard Scooter obtain the power that advances with single pedal ground every now and then when using, therefore be not suitable as the instrument of walking-replacing tool, and, therefore be not suitable for the elderly and use owing to require balanced capacity better.
(2) two take turns Segway Human Transporter, are the Kickboard Scooter of a kind of motorized motions of 02262556.9 patent disclosure as the patent No., are used as power by storage battery and motor, and weight is heavier, mainly does walking-replacing tool, and are not suitable for doing amusement body-building and use.
(3) the three-wheel manpower drives Kickboard Scooter.It as the patent No. pedal power device of a kind of three-wheel scooter of 02205908.3 patent disclosure, this Kickboard Scooter has overcome the weak point of user with the feet step on the ground, and the user stands on the Kickboard Scooter, constantly steps on a pedal, through driving system, drive the Kickboard Scooter motion.But this three-wheel scooter is complex structure not only, and weight is heavier, is inconvenient to use.
Summary of the invention
The purpose of this utility model provides a kind of body-building scooter, and this device not only helps person in middle and old age, the teenager carries out recreational body building, and simple in structure, easy to operate.
The technical solution of the utility model is achieved in that it comprises vehicle frame, described vehicle frame front side labour contractor below is provided with front-wheel, described vehicle frame rear portion has been horizontally set with hind axle, the both sides of described hind axle are connected with a trailing wheel respectively, it is characterized in that: also be horizontally set with a sprocket wheel rotating shaft that parallels with hind axle on the described vehicle frame, described sprocket wheel rotating shaft drives hind axle through driving chain wheel mechanism and rotates, the major diameter drive sprocket of described driving chain wheel mechanism is fixedly connected in the sprocket wheel rotating shaft, the minor diameter driven sprocket of described chain wheel driving mechanism is installed on the hind axle, also be horizontally set with a middle part on the described vehicle frame and be hinged on seesaw on the vehicle frame, the perpendicular respectively liftable tooth bar that is provided with in described seesaw both sides, described liftable tooth bar top vertically is connected with pedal, the top, both sides of described seesaw is hinged with and is used for cooperating the roller that contacts with the pedal bottom side, the ratchet and pawl arrangement of described liftable tooth bar through being connected sprocket wheel rotating shaft both sides realized the driving to the sprocket wheel rotating shaft, the external side end of the ratchet of described ratchet and pawl arrangement be provided with coaxial ratchet and be cured as one and with liftable tooth bar mating gear, described ratchet is meshed with ratchet coaxial with the sprocket wheel rotating shaft and that be fixed in the sprocket wheel rotating shaft on being located at the sprocket wheel rotating shaft, when stepping under the described pedal, the ratchet and pawl arrangement that is fixed on the same side of sprocket wheel rotating shaft through the liftable rack drives drives the chain wheel driving mechanism operation, simultaneously through sticking up horizontal reset on the pedal that bar drives another side.
The utility model has the advantages that simple in structurely, easy to operate, exercise intensity is moderate, be easy to keep balance, be applicable to person in middle and old age, teen-age recreational body building, broken traditional manpower and driven the limitation that Kickboard Scooter uses the crowd to have vast potential for future development.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated.
As shown in the figure, the utility model relates to a kind of body-building scooter, comprise vehicle frame (3), described vehicle frame front side labour contractor (1) below is provided with front-wheel (2), described vehicle frame rear portion has been horizontally set with hind axle (13), the both sides of described hind axle are connected with a trailing wheel (12) respectively, it is characterized in that: also be horizontally set with a sprocket wheel rotating shaft (10) that parallels with hind axle on the described vehicle frame, described sprocket wheel rotating shaft drives hind axle through driving chain wheel mechanism (11) and rotates, the major diameter drive sprocket (8) of described driving chain wheel mechanism is fixedly connected in the sprocket wheel rotating shaft, the minor diameter driven sprocket (14) of described chain wheel driving mechanism is installed on the hind axle, also be horizontally set with a middle part on the described vehicle frame and be hinged on seesaw (4) on the vehicle frame, the perpendicular respectively liftable tooth bar (7) that is provided with in described seesaw both sides, described liftable tooth bar top vertically is connected with pedal (5), the top, both sides of described seesaw is hinged with and is used for cooperating the roller (15) that contacts with the pedal bottom side, the ratchet and pawl arrangement (9) of described liftable tooth bar through being connected sprocket wheel rotating shaft both sides realized the driving to the sprocket wheel rotating shaft, the external side end of the ratchet of described ratchet and pawl arrangement (16) be provided with coaxial ratchet and be cured as one and with liftable tooth bar mating gear, described ratchet is meshed with ratchet (17) coaxial with the sprocket wheel rotating shaft and that be fixed in the sprocket wheel rotating shaft on being located at the sprocket wheel rotating shaft, when stepping under the described pedal, the ratchet and pawl arrangement that is fixed on the same side of sprocket wheel rotating shaft through the liftable rack drives drives the chain wheel driving mechanism operation, simultaneously through sticking up horizontal reset on the pedal that bar drives another side.
The perpendicular guide groove (6) of two openings that be provided with on the above-mentioned vehicle frame towards rear side.
Principle of work of the present utility model is such: user's both feet place on the pedal, and when one side pin was stepped on pedal downwards, the liftable tooth bar of captiveing joint with this pedal moved downward with pedal, rotate thereby drive the gear that is engaged with.The ratchet that is cured as one with gear rotates in the counterclockwise direction, and this moment, ratchet was clamped on the ratchet, rotates thereby drive the sprocket wheel rotating shaft along with the rotation of ratchet, drives hind axle with the drive sprocket transmission device and rotates, and moves ahead thereby drive body-building vehicle.The pedal of opposite side horizontal reset under the effect of seesaw simultaneously, the liftable tooth bar of captiveing joint with this pedal rotates thereby drive the gear that is engaged with the pedal upward movement.The ratchet that is cured as one with gear rotates along clockwise direction, and ratchet idle running this moment does not drive ratchet and rotates.
The utility model is simple in structure, and is easy to operate, and exercise intensity is moderate, is easy to keep balance, is applicable to person in middle and old age, teen-age recreational body building, broken traditional manpower and driven the limitation that Kickboard Scooter uses the crowd, has vast potential for future development.
