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, particularly relate 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 push away passerby when need adjust the front line direction of front-wheel, need to apply the thrust turned to go-cart, so not only turn to inconvenience, and when front-wheel is two, not easily control its synchronism turned to preferably.
Summary of the invention
the present invention seeks to: the foresteerage gear of the doll carriage providing a kind of structure simple, easy to operate.
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 can push rod of its motion relatively, interlinked mechanism is provided with between described push rod and front component, during described pushrod movement, push rod drives front component to realize turning to by interlinked mechanism.
one of further technical scheme: described front component is one, 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.
further technical scheme two: described front component is two, swing arm is connected with between the permanent seat of this two front component, in two front components, the permanent seat of side front component is provided with tumbler, and described interlinked mechanism is the drive link of pin joint between tumbler and push rod.
further, described push rod can rotate relatively with vehicle frame, 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 extended to side, described tumbler is sheathed on corresponding S. A., and tumbler is provided with the connecting strap extended in the same way with fixed plate, described drive link is pinned between this fixed plate and connecting strap, when push rod rotates, push rod drives front component to realize rotating in same direction by interlinked mechanism.
advantage of the present invention is:
1, structure of the present invention is simple, easy to operate, pushes away the front line direction that can adjust front-wheel when passerby carries out like a cork as required.
, the present invention being when having two front components and need turn to, only need rotating push rod, drive link bottom push rod drives the tumbler of side front component to rotate, swing arm simultaneously between two front components drives another front component synchronous axial system, and then two front components is had turn to synchronism preferably.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the invention will be further described:
fig. 1, Fig. 2 are the schematic diagram 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.
Detailed description of the invention
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 can push rod 3 of its motion relatively, interlinked mechanism 4 is provided with between described push rod 3 and front component 1, when described push rod 3 moves, push rod 3 drives front component 1 to realize turning to by interlinked mechanism 4.
further, front component described in the present embodiment is two, swing arm 5 is connected with between the permanent seat 11 of this two front component 1, in two front components 1, the permanent seat 11 of side front component 1 is provided with tumbler 12, 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 can rotate relatively 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 extended to side, described tumbler 12 is sheathed on S. A. 13, and tumbler 12 is provided with the connecting strap 121 extended in the same way with fixed plate 32, and described drive link 41 is pinned between this fixed plate 32 and connecting strap 121.
during steering operation of the present invention, rotating push rod 3, when push rod 3 rotates along F1 direction, drive link 41 is driven to move to F2 direction, now drive link 41 drives the tumbler 12 of side front component 1a to rotate along F1 direction, swing arm 5 simultaneously between two front components 1 moves along F3 direction, and drive another front component 1b along F1 direction synchronous axial system, structure of the present invention is simple, easy to operate, push away the front line direction that can adjust front-wheel when passerby carries out like a cork as required, and before making two, wheels 1a, 1b part has and turns to synchronism preferably.
below be only embody rule example 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.
