Abstract
The utility model discloses a manual pram composed of a pram body (1), a steering wheel (2), a front wheel (3) and two back wheels (4), wherein a rotating shaft of the steering wheel (2) is perpendicular to the ground plane, a wheel shaft of the front wheel (3) is fixedly connected with the rotating shaft of the steering wheel (2) in an eccentric way and can rotate along with the steering wheel (2), and the external surface of the wheel flange of the front wheel (3) is in a cylinder face shape. By adopting the structure, when the steering wheel (2) is rotated back and forth by hands, the pram of the utility model can run and can move forwards or backwards conveniently.
Description
The utility model relates to a kind of perambulator.
The perambulator of Chu Shouing is foot-operated in the market, this perambulator has a front-wheel and two trailing wheels, the wheel shaft of front-wheel and the rotating shaft of bearing circle are fixedly connected with the control travel direction, and it also has foot-operated that a pair of and wheel shaft front-wheel be fixedly connected, the profit foot-operated driving dynamics that provides that tramps with one's feet.
It is the perambulator of power with the hand that the purpose of this utility model provides a kind of.
For achieving the above object, the utility model perambulator is made up of car body, bearing circle, a front-wheel, two trailing wheels, the rotating shaft of bearing circle is perpendicular to ground level, and the wheel shaft of the front-wheel of perambulator is fixedly connected with the rotating shaft of bearing circle prejudicially, and the rim outer surface of this front-wheel is shaped as the face of cylinder.
After adopting such structure, only need steering wheel rotation back and forth when children ride, can drive perambulator and travel.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view of the utility model perambulator.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 1 to Fig. 2 has provided a kind of specific embodiment of the utility model perambulator, it is by car body 1, bearing circle 2, a front-wheel 3, two trailing wheels 4 are formed, the rotating shaft of bearing circle 2 is perpendicular to ground level, the wheel shaft of front-wheel 3 is fixedly connected with the rotating shaft of bearing circle 2 prejudicially and can does 360 ° of revolutions with bearing circle 2, the rim outer surface of this front-wheel 3 is shaped as the face of cylinder, after adopting such structure, when steering wheel rotation 2 back and forth, front-wheel 3 travels with the frictional force drives perambulator that the contact position, ground can produce the deflection travel direction, because bearing circle 2 can be done 360 ° of revolutions with front-wheel 3, therefore the utility model perambulator can advance or retreat easily, for guaranteeing that the utility model perambulator has suitable moving velocity and suitable children to ride, the wheel of this front-wheel 3 is wide between 15mm-60mm, the interaxle eccentric distance of the commentaries on classics of the wheel shaft of front-wheel 3 and bearing circle 2 is between 60mm-150mm, the distance that the rotating shaft of bearing circle 2 and trailing wheel are 4 is comparatively suitable between 350mm-500mm.Safety when guaranteeing that children ride can respectively be adorned a protection wheel 5 to prevent the perambulator overturning in the both sides of the front end of the utility model perambulator, and during cruising, the bottom of protection wheel 5 is a little more than ground.Certainly, the utility model perambulator can not adorned foot-operatedly when implementing, and fully by manually travelling, also can install a pair of foot-operatedly on the wheel shaft of front-wheel 3, and also can profit when needing tramping with one's feet to ride provides power.
