Abstract
The invention discloses a front wheel steering mechanism for a baby stroller. The front wheel steering mechanism comprises a front wheel component and a frame. A pushrod capable of moving relative to the frame is arranged on the rear part of the frame. A linking mechanism is arranged between the pushrod and the front wheel component. The pushrod drives the front wheel component through the linking mechanism to realize steering whenduring rotating. The front wheel steering mechanism is wholly simple in structure and convenient to operate, and a pusher can easily regulate the advancing direction of front wheels according to needs when pushing the baby stroller.
Description
Technical field
The present invention relates to a kind of doll carriage, relate in particular to a kind of foresteerage gear of doll carriage.
Background technology
Existing doll carriage comprises vehicle frame, front component and wheel assembly, it is when carrying out, if when pushing away the front line direction of passerby's need adjustment front-wheel, need to apply a thrust that turns to go-cart, so not only turn to inconvenience, and when front-wheel is two, be difficult for controlling preferably the synchronism that it turns to.
Summary of the invention
The present invention seeks to: the foresteerage gear that a kind of simple in structure, easy to operate doll carriage is provided.
Technical scheme of the present invention is: a kind of foresteerage gear of doll carriage, comprise front component and vehicle frame, the rear portion of described vehicle frame has the relatively push rod of its motion, be provided with interlinked mechanism between described push rod and the front component, during described pushrod movement, push rod drives front component by interlinked mechanism and realizes turning to.
One of further technical scheme: described front component is one, and this front component permanent seat is provided with tumbler, and described interlinked mechanism is the drive link of pin joint between tumbler and push rod.
Two of further technical scheme: described front component is two, be connected with swing arm between the permanent seat of this two front component, the permanent seat of a side front component is provided with tumbler in two front components, and described interlinked mechanism is the drive link of pin joint between tumbler and push rod.
Further, described push rod and vehicle frame are can be counterrotating, the rear portion of described vehicle frame has the sleeve of longitudinal extension, described push rod is plugged in this sleeve and two ends stretch out in sleeve, the upper end of push rod has handle, the bottom of push rod is provided with the fixed plate that extends to a side, described tumbler is sheathed on the corresponding S. A., and tumbler is provided with the connecting strap that extends in the same way with fixed plate, described drive link is pinned between this fixed plate and the connecting strap, during the push rod rotation, push rod drives front component by interlinked mechanism and realizes rotating in same direction.
Advantage of the present invention is:
1, the present invention is simple in structure, and is easy to operate, pushes away the front line direction that can adjust as required like a cork front-wheel when passerby carries out.
, the present invention has two front components and need turn to the time, only need rotating push rod, the tumbler that the drive link of push rod bottom drives a side front component rotates, swing arm between while two front components drives another front component and rotates synchronously, and then turns to preferably synchronism so that two front components have.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1, Fig. 2 are the scheme drawing of the invention process state;
Fig. 3 is structural representation of the present invention.
Wherein: 1 front component; 11 permanent seats; 12 tumblers; 121 connecting straps; 13 S. A.s;
2 vehicle frames; 21 sleeves;
3 push rods; 31 handles; 32 fixed plates;
4 interlinked mechanisms; 41 drive links;
5 swing arms.
The specific embodiment
Embodiment: as shown in Figure 1 to Figure 3, a kind of foresteerage gear of doll carriage, comprise front component 1 and vehicle frame 2, the rear portion of described vehicle frame 2 has the push rod 3 of relatively its motion, be provided with interlinked mechanism 4 between described push rod 3 and the front component 1, during described push rod 3 motion, push rod 3 drives front component 1 by interlinked mechanism 4 and realizes turning to.
Further, front component described in the present embodiment is two, be connected with swing arm 5 between the permanent seat 11 of this two front component 1, the permanent seat 11 of a side front component 1 is provided with tumbler 12 in two front components 1, and described interlinked mechanism 4 is the drive link 41 of pin joint between this tumbler 12 and push rod 3.Described push rod 3 is can be counterrotating with vehicle frame 2, the rear portion of described vehicle frame 2 has the sleeve 21 of longitudinal extension, described push rod 3 is plugged in this sleeve 21 and two ends stretch out in sleeve 21, the upper end of push rod 3 has handle 31, the bottom of push rod 3 is provided with the fixed plate 32 that extends to a side, described tumbler 12 is sheathed on the S. A. 13, and tumbler 12 is provided with the connecting strap 121 that extends in the same way with fixed plate 32, and described drive link 41 is pinned between this fixed plate 32 and the connecting strap 121.
During steering operation of the present invention, rotating push rod 3, when push rod 3 during along the F1 direction rotation, driving drive link 41 moves to the F2 direction, the tumbler 12 of drive link 41 drives this moment one side front component 1a rotates along the F1 direction, swing arm 5 between two front components 1 moves along the F3 direction simultaneously, and drive another front component 1b and rotate synchronously along the F1 direction, the present invention is simple in structure, easy to operate, push away the front line direction that can adjust as required like a cork front-wheel when passerby carries out, and so that two front wheels 1a, 1b spare have and turn to preferably synchronism.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
