Detailed description of the invention
as shown in Fig. 1 to 5, a kind of children trolley described in the utility model, comprises vehicle wheel component 1, push rod 6 that the lower support bridge 2 that lower end is fixedly connected with vehicle wheel component 1, the upper support bar frame 3 be fixedly rotationally connected with lower support bridge 2 respectively and top rod 4 and bottom and top rod 4 top are rotationally connected.Described push rod 6, upper support bar frame 3, top rod 4 and lower support frame 2 form four-bar linkage.Top and the push rod 6 of described upper support bar frame 3 are rotationally connected, and the top of described upper support bar frame 3 and push rod 6 are rotationally connected and are positioned at above the junction of top rod 4 on push rod 6 everywhere.Described upper support bar frame 3 is positioned at before top rod 4.Described children trolley also comprise for the protection of children and for children hand steered before armrest assembly 5; described front armrest assembly 5 is arranged in four-bar linkage; and be rotationally connected with upper support bar frame 3 and top rod 4 respectively, the size adjustable of described front armrest assembly 5 between upper support bar frame 2 and top rod 4 is whole.Described push rod 6, upper support bar frame 3, front armrest assembly 5 and top rod 4 form slider-crank mechanism.Described children trolley has mode of operation and folded state two states, when children trolley is in running order, described upper support bar frame 3 and top rod 4 launch tiltedly vertical towards the direction away from lower support bridge 2, described top rod 4 launches roughly in alignment with push rod 6, described upper support bar frame 3 diagonal brace is on push rod 6, and described front armrest assembly 5 support stands on upper support bar frame 3 and top rod 4; When children trolley is in folded state, described push rod 6 overturns bracing member 3, top rod 4 and lower support bridge 2 upward and draws close, described upper support bar frame 3 and top rod 4 overturn bracing member 2 down and draw close, and in the switching process of described front armrest assembly 5, draw close upward by bracing member 3, top rod 4 and lower support bridge 2 for adjust size.
in the present embodiment, described front armrest assembly 5 comprises front handrail body 51 and front handrail attaching parts 52, and the U-shaped of described front handrail body 51 in both ends open is shaft-like.Described front handrail body 51 is fixedly being rotationally connected near two ends place and upper support bar frame 3, and described front handrail attaching parts 52 is fixedly rotationally connected with top rod 4, described front handrail body 51 and front handrail attaching parts 52 sliding block joint mutually.
one of them parts of described front handrail body 51 and front handrail attaching parts 52 offer and extends to end and form the chute 53 of opening in end, another parts to be inserted in chute 53 and can to slide along the bearing of trend of chute 53 in chute 53.
in this example, the both ends that described front handrail body 51 opens offer chute 53, the linearly structure of described front handrail attaching parts 52, and described front handrail attaching parts 52 is inserted in chute 53 and front handrail body 51 sliding block joint.
when children trolley is in folded state, described front handrail body 51 is drawn close mutually with upper support bar frame 3, and described front handrail attaching parts 52 is drawn close mutually with top rod 4.Like this, children trolley is when folded state, front armrest assembly 5 is also folded together with parts are drawn close with vehicle wheel component 1, lower support bridge 2, upper support bar frame 3, top rod 4 etc., and the children trolley that the volume ratio taken fixes not folding front handrail is little a lot, is convenient to store and carry.
when children trolley is in running order, described front handrail body 51 support stands on upper support bar frame 3, and described front handrail attaching parts 52 support stands on top rod 4.Front handrail body 51 is plugged in together formation rigid support with front handrail attaching parts 52, front armrest assembly 5 entirety is made to have stronger anti-ability of toppling over, will, at the mode of operation of children trolley because self gravitation effect is toppled over to upper support frame 3 and top rod 4 direction, children be can be used for grip support.
when children trolley is changed from folded state to mode of operation, described front handrail body 51 is launched to the direction away from upper support bar frame 3, described front handrail attaching parts 52 to the direction away from top rod 4 launch and simultaneously before handrail body 51 and front handrail attaching parts 52 relative sliding.This structure is not only simple but also be convenient to the folding of front armrest assembly 5 or launch motion, very practical.
as mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
