Described dragline is a Yi Duan Brake fare.
Described driving lever is the hank chain mechanism.
Described front fork is a plate work piece, and there is a circular hole centre, and both sides are fork-shaped.
By stirring driving lever, can adjust the stroke of locking piece, make slip or fixing in its draw-in groove on rotating disc, change orientation thereby realize adjusting front-wheel.
Advantage of the present utility model is,
In the process of walking, when running into obstacle or need turning, only need just can easily detour, and can prevent that children from avoiding scaring therebetween at this, especially outstanding car body the steady of displacement of advancing, flexible characteristic, easy-to-operate by stirring driving lever.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a work structuring scheme drawing of the present utility model;
Fig. 3 is a structural upright exploded drawings of the present utility model.
The specific embodiment
As Fig. 1～shown in Figure 3, baby's perambulator front-wheel that the utility model provides changes orienting device, is installed on baby's frame for baby cart front fork tube 4; It comprises steering hardware 1, attitude reference device 2, damping 3; Wherein, steering hardware 1 comprises adapter plate 11, rotating disc 12; Adapter plate 11 is an iron plate, and a circular hole is arranged above, and its profile and front fork tube shape match, and are fixed in front fork tube 4, has a through hole 110 on it; Rotating disc 12, its center fixation one pivot shaft 13, this pivot shaft 13 is arranged in the through hole 110 on the adapter plate 11, and sheathed bearing 14 and captive nut 15, and rotating disc 12 and adapter plate 11 are flexibly connected; Also have a draw-in groove 121 on this rotating disc 12; Rotating disc 12 both sides are provided with the front fork 6 that connects front-wheel 5; Described front fork is a plate work piece, and there is a circular hole centre, and both sides are fork-shaped.
Damping 3 comprises shock-absorbing sleeve 31, damping spring 32, end cap 33; Shock-absorbing sleeve 31 is sheathed on pivot shaft 13, and is fixed on the rotating disc 12, and its inwall is provided with step (figure does not show); Damping spring 32 is sheathed on pivot shaft 13, and the one end is butted on the step of shock-absorbing sleeve 31 inwalls, and described shock-absorbing sleeve 31 is a hollow ladder cylinder, and the upside outer wall is provided with an elongated slot; End cap 33 is sheathed on pivot shaft 13, and it is an annulus, and a manhole is arranged on the lateral surface, is connected and fixed with pivot shaft 13, and the one end is resisted against damping spring 32, plays the effect of damping when bearing pressure.
By stirring driving lever 25, can adjust the stroke of locking piece 22, make slip or fixing in its draw-in groove 121 on rotating disc 12, change orientation thereby realize adjusting front-wheel.
When 5 rotations of needs front-wheel, only need driving lever 25 is rotated counterclockwise, at this moment, by the drive of dragline 24, locking piece 22 upwards rises, and breaks away from the draw-in groove 121 on the rotating disc 12, and retracing spring 23 is in compressive state; At this moment, front-wheel 5 is that the axle center is rotated with the center of rotating disc 12.
When fixing front-wheel 5, driving lever 25 is clockwise rotated, the position of locking piece 22 descends, along with the rotation of front-wheel 5, when locking piece 22 slides into draw-in groove 121 positions thereupon, under the effect of retracing spring 23, ejection downwards snaps in the draw-in groove 121, thereby realizes front-wheel 5 orientating functions, and is free and relaxed, it is very convenient to operate, and can finish whole switching processs on handle pipe.
