The utility model relates to a kind of novel baby stroller.
Background technology
Baby stroller on the existing market generally is made up of vehicle frame, front component, wheel assembly, seat, and said vehicle frame comprises brace, fixed link and stirrup; The top and the brace of said fixed link are affixed; The top of said fixed link is positioned at the upper position of brace, and the two ends of stirrup are affixed with the bottom of fixed link, brace respectively, and said chair mounted is on stirrup; The bottom of said front component and brace is affixed, and the bottom of said wheel assembly and fixed link is affixed.
The front component of existing baby stroller and wheel assembly are fixed on the same horizontal surface, cannot adjust diff-H between front component and the wheel assembly.Therefore; The shortcoming of existing baby stroller is: when the adult was holding baby stroller and takes automatic escalator, front component, wheel assembly will lay respectively on the two-stage step of differing heights of automatic escalator, and this will cause the baby stroller car body to become wide-angle tilt; The adult must exert oneself promptly, and baby stroller could guarantee that it does not slide; Cause danger preventing, when the whole height of escalator is higher, the adult must be long-time baby stroller promptly firmly; Baby in the hand barrow is very dangerous, and adult (particularly women, old man) is nervous, tired easily.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides the adjustable novel baby stroller of diff-H between a kind of simple in structure, safe, front component and the wheel assembly.
In order to achieve the above object, the technical scheme that the utility model adopted is following:
A kind of novel baby stroller; Comprise vehicle frame, front component, wheel assembly, seat; Said vehicle frame comprises brace, fixed link and stirrup, and the top of said fixed link and the top of brace are affixed, and the two ends of stirrup are affixed with the bottom of fixed link, brace respectively; Said chair mounted is on stirrup, and the bottom of said front component and brace is affixed; This novel baby stroller also comprises composite rod pushing mechanism, wheel assembly telescoping mechanism; The top of wheel assembly telescoping mechanism, brace flexibly connects with the composite rod pushing mechanism respectively, said wheel assembly telescoping mechanism and fixed link sliding block joint, and the bottom of said wheel assembly and wheel assembly telescoping mechanism is affixed.
As preferably, said composite rod pushing mechanism comprises handle, pipe link, strut bar and push rod; One end of said handle and the top of brace are hinged, and an end of the other end and pipe link is hinged; One end of strut bar, an end of push rod are hinged with the other end of pipe link respectively; The other end and the brace of said strut bar are hinged, and the other end of said strut bar is between the top of the top of fixed link and brace; The other end of said push rod and wheel assembly telescoping mechanism are hinged.
As preferably, said wheel assembly telescoping mechanism comprises slide bar, and said fixed link is socketed in the slide bar, and the bottom and the wheel assembly of said slide bar are affixed, and the other end and the slide bar of said push rod are hinged.
As preferably, an affixed contiguous block on the said slide bar, said contiguous block is provided with groove, is provided with pivot pin in the said groove, and the other end of said push rod is connected with pivot pin.
As preferably, said fixed link is provided with a plurality of guide rollers, the inboard butt of said guide roller and slide bar.
As preferably, said seat and stirrup are hinged.
The utility model compared with prior art; Utilize composite rod pushing mechanism and wheel assembly telescoping mechanism, realize that the wheel assembly of novel baby stroller is scalable, promptly when taking automatic escalator; Because wheel assembly is positioned on the lower back one-level step of relative front component; The adult user promotes the handle of composite rod pushing mechanism gently, and the wheel assembly telescoping mechanism will extend automatically, thereby wheel assembly is descended until the level attitude of back one-level ladder; Like this when taking automatic escalator; Just can not produce diff-H between novel baby stroller front component and the wheel assembly, novel baby stroller integral body can remain level, thereby has eliminated the possibility that novel baby stroller glides; Improve the safety of using greatly, thereby fundamentally solved the difficulty that runs into when existing novel baby stroller is taken automatic escalator.
