Technical field
The utility model relates to the universal control setup of a kind of Baby's tricycle front-wheel, specifically is meant a kind of universal control setup of Baby's tricycle front-wheel that turns to the dead band that turns to flexibly, do not exist.
Background technology
The child when controlling Baby's tricycle often correctly controlling party to, need the adult to grasp direction because the Baby's tricycle integral structure is short and small, the adult need bend over controlling party to, do not add direction control mechanism in addition and then operate very inconvenient.Referring to Fig. 1, Fig. 1 is the structural representation of the existing universal control setup of Baby's tricycle front-wheel, comprise and lay respectively at the actuating spindle 1 that body rear end and vehicle body are rotatably connected, controlled shaft 2 with end turning mechanism interlock before the Baby's tricycle, be fixedly connected with the projection 4 that stretches out from side on the actuating spindle 1, projection 4 is hinged with rigidity connecting rod 5, the other end of rigidity connecting rod 5 and controlled shaft 2 are hinged, actuating spindle 1 is provided with and turns to handle 7, rotation turns to handle 7, actuating spindle 1 push-and-pull rigidity connecting rod 5, drive controlled shaft 2 circumferential movement, actuating spindle 1 rotates perambulator by tap, thereby realizes the direction control of Baby's tricycle.The defective of the universal control setup of this Baby's tricycle front-wheel is: the rigidity connecting rod can only provide a unidirectional power to realize turning to, and the direction of power is changing always, and the thing followed is to need the size of power also to change always, gives people's sensation very not nimble.This in addition situation has the existence of a kind of stressed dead angle, and when the direction of power was passed through the axle center of controlled shaft 2, this moment, moment was zero, and it is impossible changing rotation direction, so the also restricted property of the rotational angle of controlled shaft.
Summary of the invention
The utility model provides a kind of and turns to flexibly for solving the defective that prior art exists, do not exist to turn to the dead band, but the universal control setup of Baby's tricycle front-wheel that full angle turns to.
The technical solution of the utility model is:
The universal control setup of a kind of Baby's tricycle front-wheel, comprise controlled shaft with the interlock of body structure steering hardware, the actuating spindle that links to each other with controlled shaft by control mechanism, described control mechanism is the flexible strand body that connects between controlled shaft and the actuating spindle, flexible strand body and controlled shaft and actuating spindle are intertwined and connected, the flexible strand body twines back left-handed one side dextrorotation on one side on diaxon, the rope body on both sides produces the two-way motive force of left-handed or dextrorotation to controlled shaft.
Described actuating spindle is provided with perforation, and controlled shaft is provided with perforation, and described flexible strand body passes actuating spindle perforation and controlled shaft perforation, one side the dextrorotation of left-handed one side walk around controlled shaft and actuating spindle respectively.
Described flexible strand body is captiveed joint with the controlled shaft side with actuating spindle, and actuating spindle and controlled shaft are walked around in the left-handed one side dextrorotation on one side of described flexible strand body respectively.
Described flexible strand body is captiveed joint with the actuating spindle side, and actuating spindle is walked around in left-handed one side dextrorotation on one side respectively; Described controlled shaft is provided with perforation, and the flexible strand body passes controlled shaft perforation left-handed one side dextrorotation on one side and walks around controlled shaft respectively.
The beneficial effects of the utility model are: the footpath at controlled shaft upwards applies pulling force, when rotating, different directions uses the power of different directions, what control it is the flexible strand body, because flexible material can pitch of the laps, do not have the problem of the direction of power, solved the problem that has the dead angle in the rotation process, and the direction of power is tangent with axle always by the axle center, the size of power also remains unchanged, and rotates flexibly.
