Description
Technical field
The present invention relates to a kind of baby stroller, more particularly to a kind of front and back wheel it is all rotatable, can be commutated by handle pipe
Come the front and back wheel automatic orientation mechanism of front and back wheel baby stroller controlled.
Background technology
Baby stroller is the favorite stroll vehicles of baby, necessary when even more father and mother go shopping with baby
Product.But according to the growth of baby, use, baby stroller is segmented into many types, such as A types and Type B again, A types are
The spacious and comfortful type trolley begun to use greatly for two months, Type B is the light good portable trolley begun to use greatly for 6 months.
The structure of trolley it is general by awning, it is seat cushion, the chair back, handle, retracting structure, skeleton, safety belt, preceding guardrail, storing basket, anti-
Shake device, brake device, height adjuster and various perambulator additives.
The wheel attitude reference device of existing baby stroller on the market is typically only made in front-wheel, trailing wheel Bu Zuo attitude reference devices,
And general hand push back wheels of vehicle cannot rotate, when product can before and after two-way push when, because trailing wheel can not be turned to and be caused
Carry out inconvenience of turning, it is relatively elaborate.
Thus, the wheel attitude reference device of existing doll carriage on the market typically has two kinds：One kind is manual orientation, be exactly according to
Gone by or gone by user to push away orientation lever with hand, it has not been convenient to operate；It is a kind of be it is more advanced be automatically positioned, self-orientating side
Although formula has comparison many, but on the market it is existing have attitude reference device design in front foot or on the rear foot.Therefore, for the above
Aspect is, it is necessary to reasonably be improved prior art.
The content of the invention
For disadvantages described above, the present invention provides a kind of front and back wheel automatic orientation mechanism of baby stroller, by attitude reference device
Motility device be arranged on trolley two side handrails on, the automatic orientation of front and back wheel is realized by the front and rear commutation of handle pipe
Oriented with releasing, to solve many deficiencies of prior art.
To achieve the above object, the present invention uses following technical scheme：
A kind of front and back wheel automatic orientation mechanism of baby stroller, including side handrail group, handle pipe, front foot group, rear foot group,
By rivet together, the side handrail group is turned round by side handrail plastic cement, reset for the side handrail group, front foot group, rear foot group
Spring, directional-rotation plastic cement composition, side handrail plastic cement end therein, which is set, installs orientation on reduction torsion spring and this reduction torsion spring
Rotate plastic cement, the side handrail plastic cement end, reduction torsion spring and directional-rotation plastic cement by rivet together；
The upper end of the front foot group in front foot pipe close, oriented sliding plastic cement, directional homing torsion spring, front foot orientation bracing wire,
Front foot pipe and rivet composition, in front foot therein pipe close, oriented sliding plastic cement and front foot pipe by rivet together,
Oriented sliding plastic cement therein from top to bottom opens up groove, i.e. elongated slot, pull-down line neck, pull-up line card groove successively；Orientation therein
Slide plastic cement to be assemblied in the hole slot that pipe close upper end is opened up in front foot, front foot orientation bracing wire upper end therein is fixed on drop-down line card
In groove, rear foot orientation bracing wire is fixedly mounted inside pull-up line card groove therein, on oriented sliding plastic cement and front foot between pipe close
It is equipped with directional homing torsion spring；
The front foot group lower end is made up of orientation bayonet lock, rotation wheel seat, front foot base, and the front foot orientation bracing wire lower end is consolidated
It is scheduled on orientation bayonet lock；
The rear foot group upper end is equipped with pipe close on the rear foot, and orientation bayonet lock is equipped with rear foot orientation bracing wire lower end, wherein
The rear foot orientation bracing wire lower end be securely fitted on the orientation bayonet lock of the rear foot；
When handle pipe from when commutating to above next below, the commutation link stopper in handle pipe revolves the orientation on Chu Touch side handrails
Turn plastic cement, directional-rotation plastic cement is pulled down and moved under oriented sliding plastic cement, oriented sliding plastic cement drive front foot orient bracing wire to
Lower motion；Then, the bracing wire of front foot orientation pulls the orientation bayonet lock of front foot to stick into the hole clipping of rotation wheel seat design, due to orientation card
Pin card, which is lived, rotates wheel seat, and rotation wheel seat can not be rotated freely, realize the orientation of front-wheel；At the same time, oriented sliding plastic cement
Upper end connection rear foot orientation bracing wire, now, rear foot orientation bracing wire is moved upwards, and the orientation bayonet lock for driving the rear foot is moved upwards,
Orientation bayonet lock is set to depart from the hole clipping of rotation wheel seat, the rotation wheel seat of trailing wheel will be freely rotatable；
When handle pipe is from when above commutating to below, directional-rotation plastic cement will revolve upwards under the active force of reduction torsion spring
Turn, release the pressure of oriented sliding plastic cement, oriented sliding plastic cement upward sliding drives front foot bracing wire to move upwards, the rear foot is fixed
Moved downward to bracing wire, the orientation bayonet lock that the orientation bayonet lock in front foot departs from the hole clipping of rotation wheel seat, the rear foot is stuck in hole clipping
In, so that the rotation plastic cement in front foot is freely rotatable, the rotation plastic cement on the rear foot can not be rotated freely, and realize commutation orientation
Function.
The handle pipe is provided with commutation link stopper.
Spring is provided between orientation bayonet lock and front foot base；
Directional-rotation plastic cement rotates certain angle around rivet；
Another spring is provided between the orientation bayonet lock and rear foot base；
Hole clipping is offered on rotation wheel seat therein.
The front and back wheel automatic orientation mechanism of baby stroller of the present invention has the beneficial effect that：By the original of attitude reference device
Power set are arranged on two side handrails of trolley, and the automatic orientation and solution of front and back wheel are realized by the front and rear commutation of handle pipe
Except orientation.
