Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
see the children trolley shown in Fig. 1 to Fig. 4, comprise there is deployed condition and folded state stroller frame, be located at wheel assembly bottom this stroller frame, for by stroller frame locking lockout mechanism in the deployed state.This stroller frame comprise lay respectively at the left and right sides side stand, to be located between the side stand of both sides and can laterally to draw in and the strut assembly launched.
shown in each accompanying drawing, the side stand of every side includes front frame 1, push rod 2, after poppet 3, seat bar 4 and strut bar 5.The top of front frame 1 is connected with the bottom phase pivot of push rod 2, the upper pivot of after poppet 3 is connected on push rod 2, seat bar 4 extends along the longitudinal direction, the front end of seat bar 4 is connected to the top of front frame 1 rotationally by connector 15, the rear end of seat bar 4 is connected on after poppet 3 rotationally by attaching parts 12.
strut bar 5 also extends along the longitudinal direction, and the front end of strut bar 5 is connected to the top of front frame 1 rotationally or is connected to the bottom of push rod 2 rotationally, and the front end of this strut bar 5 is between the front end of seat bar 4 and the upper end of after poppet 3.In the present embodiment, the lower end of the front end of strut bar 5, the upper end of front frame 1 and push rod 2 pivots together.The rear end of strut bar 5 is then connected with a sliding part 6 rotationally, and this sliding part 6 is located on after poppet 3 slidably along the length bearing of trend of after poppet 3.Sliding part 6 can adopt sliding sleeve, also can adopt as the slide block in the present embodiment, and the chute 31 of guiding when after poppet 3 is provided with for providing slide block 6 to slide up and down along its length bearing of trend, slide block 6 slides up and down to be located on after poppet 3 along the bearing of trend of chute 31.On the side stand of the same side, sliding part 6 is positioned at the top of attaching parts 12.
in the present embodiment, strut assembly comprises the rear cross assembly 7 be located between both sides after poppet 3, this rear cross assembly 7 comprises and mutually intersecting and two rear poles 71 connected at infall phase pivot, every root rear pole 71 is arranged all in the following manner: the provided at one of rear pole 71 is connected on side after poppet 3, and the other end of rear pole 71 is pivotally connected on the sliding part 6 of opposite side.Wherein, one end of rear pole 71 is pivotally connected on after poppet 3 by rotating shaft 72, and on the after poppet 3 of the same side, rotating shaft 72 is positioned at the below of sliding part 6, to avoid the formation of the stop of sliding to sliding part 6.Here, attaching parts 12 is located between sliding part 6 and rotating shaft 72 on after poppet 3.Certainly, strut assembly also can adopt other version, only needs it can realize horizontal spreading between the side stand of both sides and draw in.
shown in each accompanying drawing, this children trolley is three-wheeled cart, the front lower ends of the front frame 1 of both sides to be rotated connection by adaptor 11, like this, when rear cross assembly 7 draws in left-right direction, the after poppet 3 of both sides draws in left-right direction, and the front frame 1 of both sides also rotates relative to adaptor 11 respectively and mutually draws close in left-right direction.Wheel assembly comprises the front-wheel 10 be located at bottom adaptor 11 and two trailing wheels 20 be located at bottom both sides after poppet 3.
shown in each accompanying drawing, on the side stand of both sides, the top of push rod 2 is equipped with pulling handle rod 9, pulling handle rod 9 is rotatably set in the top of push rod 2 around the axial line of push rod 2, between the pulling handle rod 9 of both sides, phase pivot connects, when the side stand of both sides is drawn close in left-right direction mutually, the pulling handle rod 9 of both sides relatively rotates, and drives the push rod 2 of both sides mutually to draw close in left-right direction.
this stroller frame is also provided with front handrail 8 and tarpaulin rod 14, front handrail 8 is removably mounted between the top of front frame 1 of both sides, and tarpaulin rod 14 is removably mounted on both sides push rod 2 for installation tilt.
in the present embodiment, in stroller frame, lockout mechanism is be located at the locking piece (not shown) for both being locked between sliding part 6 and after poppet 3, and this locking piece can adopt the common version matched with lockhole as dead bolt.
shown in Fig. 1, Fig. 2, this stroller frame launch and lockout mechanism locking time, rear cross assembly 7 launches in left-right direction and is supported between the after poppet 3 of both sides, stable triangular structure is formed between after poppet 3, push rod 2 and strut bar 5, stable quadrilateral structure is formed, under stroller frame is in stable expanded position between front frame 1, seat bar 4, after poppet 3 and strut bar 5.
when stroller frame is folded up by needs, first front handrail 8 is disassembled with tarpaulin rod 14, then lockout mechanism is unlocked, make sliding part 6 along after poppet 3 upward sliding, under the effect of strut bar 5, the front end of the lower end of push rod 2, the upper end of front frame 1 and strut bar 5 all travels forward, and makes push rod 2 turn over and draw close to after poppet 3 gradually, and the front end of seat bar 4 gradually up drive seat bar 4 is little by little drawn close to after poppet 3 with front frame 1.Simultaneously, the up upper end upward movement making rear pole 71 of sliding part 6, two rear poles 71 of rear cross assembly 7 relatively rotate and then make the after poppet 3 of both sides to draw close in left-right direction, drive the push rod 2 of both sides and front frame 1 relatively to rotate to draw close, as shown in Figure 3, finally, the front frame 1 of both sides, push rod 2, after poppet 3, seat bar 4 and strut bar 5 are all closely drawn close together, and two rear poles 71 of rear cross assembly 7 draw between the side stand of both sides.Compact conformation after folding, takes up room less.
when stroller frame is launched by needs, then upwards lift push rod 2, the lower end of push rod 2 moves downward and drives the upper end of front frame 1 and the front end of strut bar 5 to move downward, under the effect of strut bar 5, sliding part 6 is along after poppet 3 slide downward, make push rod 2, launch gradually between after poppet 3 and strut bar 5, also make the relative after poppet 3 of front frame 1 launch gradually simultaneously, two rear poles 71 of rear cross assembly 7 relatively rotate and launch gradually in left-right direction, until after stroller frame launches completely, lockout mechanism locks, install front handrail 8 and tarpaulin rod 14 again, the expansion of go-cart has operated.
