Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
all this children trolley to be installed in use about the definition of direction below, on children trolley, viewed direction defines children's sitting, the left and right directions shown in fore-and-aft direction that is Fig. 2, Fig. 4, and wherein left is front, right-hand be after, the above-below direction in above-below direction that is each accompanying drawing.
referring to the children trolley shown in Fig. 1～4, comprise have deployed condition and folded state go-cart vehicle frame, be located at front portion at the bottom of go-cart vehicle frame front-wheel 10, be located at rear portion at the bottom of go-cart vehicle frame trailing wheel 20, be located on go-cart vehicle frame for go-cart vehicle frame being locked in to the lockout mechanism (not shown) of deployed condition.This go-cart vehicle frame comprises push rod 1, front frame 2, after poppet 3, seat bar 4, fork 5 and rear pole 6.
the bottom of push rod 1 rotates and is connected with the top of front frame 2, the top of after poppet 3 is connected at least one parts in push rod 1 and front frame 2 rotationally, in the present embodiment, the top of the bottom of push rod 1, front frame 2 and the top of after poppet 3 link together rotationally.Front-wheel 10 is arranged on the bottom of front frame 2, and trailing wheel 20 is installed on the bottom of after poppet 3.
the front portion of seat bar 4 is connected on front frame 2 rotationally by the first axle 7, and the first axle 7 is positioned at below front frame 2 and push rod 1, after poppet 3 transit points on front frame 2.One end of fork 5 connects on present bar 4 rotationally by the second axle 8, and the other end of fork 5 is connected on after poppet 3 rotationally.Under go-cart vehicle frame deployed condition, fork 5 is positioned at the below of a bar 4, and a bar 4 support along the vertical direction can be provided so to a certain extent.
rear pole 6 is located between a bar 4 and push rod 1, and the top of rear pole 6 is connected on push rod 1 rotationally, and the bottom of rear pole 6 connects on present bar 4 or fork 5 rotationally, and the bottom of rear pole 6 connects on the rear portion of present bar 4 rotationally by the 3rd axle 9 herein.Wherein, the bearing of trend of the second axle 8 edge seat bars 4 is between the first axle 7 and the 3rd axle 9.
between after poppet 3 and fork 5, lockout mechanism is set both is locked, or lockout mechanism is set at after poppet 3 and seat between bar 4 both are locked, can make go-cart vehicle frame launch time in stable deployed condition.Certainly, lockout mechanism also can be set to other versions or be located at other positions, as long as ensure that go-cart vehicle frame interfixes between each rod member under deployed condition.
