Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is further elaborated.
Referring to the children trolley shown in Fig. 1~3, including have deployed condition and folded state stroller frame, be located at the wheel assembly bottom stroller frame, for by stroller frame locking locking mechanism (not shown) in the deployed state.
This stroller frame includes fore-stock 1, after-poppet 2, push rod 3, basket rod 4. Wheel assembly includes being located at the front-wheel 20 bottom fore-stock 1 and is located at the trailing wheel 30 bottom after-poppet 2. The bottom of the top of fore-stock 1 and push rod 3 is rotated by the first axle 9 and is connected, and the top of after-poppet 2 is passed through the second axle 10 and is connected to rotationally on push rod 3. The front portion of basket rod 4 is connected on fore-stock 1 by the 3rd axle 11 rotationally, and the rear portion of basket rod 4 is connected on after-poppet 2 rotationally by the 5th axle 13.
Shown in each accompanying drawing, this stroller frame also includes the sliding sleeve 6 that can be located on push rod 3 slidably along the length bearing of trend of push rod 3, and this sliding sleeve 6 slides up and down to be located between the second axle 10 and the 3rd axle 11.When sliding sleeve 6 slides into the junction of push rod 3 and fore-stock 1, fore-stock 1 and push rod 3 all have part to be arranged in sliding sleeve 6, restriction due to sliding sleeve 6 tube chamber, push rod 3 and fore-stock 1 are relatively fixed, now sliding sleeve 6 is locked under this position, stroller frame just can be made to be in stable deployed condition; When sliding sleeve 6 departs from the junction of push rod 3 and fore-stock 1 along the length direction slip of push rod 3, can relatively rotate between push rod 3 and fore-stock 1, now stroller frame folding can be got up.
Stroller frame is additionally provided with the drawing article for pulling sliding sleeve 6 to slide along push rod 3 length direction, what this drawing article adopted herein is connecting rod 5, connecting rod 5 is distributed along the longitudinal direction, the front end of connecting rod 5 rotates with sliding sleeve 6 and is connected, the rear end of connecting rod 5 is connected on after-poppet 2 by the 4th axle 12 rotationally, the 4th axle 12 on after-poppet 2 between the second axle 10 and the 5th axle 13.
In the present embodiment, when stroller frame is launched, push rod 3 is arranged along same length direction with fore-stock 1 with extending, and the bar footpath of push rod 3 and fore-stock 1 may be configured as same diameter, and the internal diameter of this caliber and sliding sleeve 6 matches. When sliding sleeve 6 slides into push rod 3 and when being rotationally connected place of fore-stock 1, push rod 3 bottom, fore-stock 1 top all have part to be located in sliding sleeve 6 slidably, and first axle 9 also be located in the tube chamber of sliding sleeve 6, locking mechanism is locked, sliding sleeve 6 is just fixed under this position, push rod 3, fore-stock 1 sliding sleeve 6 all relatively is fixed, and stroller frame is under stable deployed condition.
Locking mechanism for locking stroller frame may be configured as the locking piece being located between fore-stock 1 top and sliding sleeve 6 for being locked on fore-stock 1 by sliding sleeve 6, may be used without the mode of the present embodiment, namely locking mechanism is the locking piece being located between push rod 3 and sliding sleeve 6 for being locked on push rod 3 by sliding sleeve 6, and the top of push rod 3 is additionally provided with the unblock handle 7 for locking mechanism is unlocked. In the present embodiment, above-mentioned locking piece adopts the fit form of lock pin and lockhole, namely lock pin is set on push rod 1, sliding sleeve 6 offers lockhole, lock pin can penetrate lockhole accordingly and locks or depart from lockhole and unlock, unlock handle 7 then with is connected hauling rope (not shown) between lock pin, make lock pin disengaging lockhole realize the unblock of locking mechanism when pulling and unlocking handle.
This stroller frame also includes the seat pocket interface 8 for mounting seat pocket assembly, this pocket interface 8 is located on sliding sleeve 6 regularly and is slided up and down with sliding sleeve 6, certainly, this pocket interface 8 also can be located on push rod 3 or fore-stock 1, as long as it does not interfere with sliding up and down the expansion realizing stroller frame and folding of sliding sleeve 6.
Shown in Fig. 1, Fig. 2, when this stroller frame is launched, locking mechanism locks, basket rod 4 is supported between fore-stock 1 and after-poppet 2 along the longitudinal direction, push rod 3 and fore-stock 1 extend along same rectilinear direction, and connecting rod 5 extends along the longitudinal direction, and the junction of fore-stock 1 and push rod 3 is arranged in sliding sleeve 6, due to the restriction of sliding sleeve 6 tube chamber, fore-stock 1 and push rod 3 are relatively fixed.
When stroller frame is folded up by needs, unblock handle 7 is then first pulled to be unlocked by locking mechanism, pressure push rod 3 then downward, push rod 3 rotates relative to after-poppet 2, and connecting rod 5 rotates relative to after-poppet 2 and drives sliding sleeve 6 along push rod 3 upward sliding, after sliding sleeve 6 departs from fore-stock 1, push rod 3 rotates relative to fore-stock 1, under the drive of basket rod 4, after-poppet 2 draws in fore-stock 1 gradually, and push rod 3 draws in after-poppet 2 gradually simultaneously.Finally, fore-stock 1, after-poppet 2, push rod 3, basket rod 4 and connecting rod 5 are drawn close mutually, form structure as shown in Figure 3.
When this stroller frame opened by needs, then it is pulled upwardly push rod 3, push rod 3 rotates relative to fore-stock 1 and rotates relative to after-poppet 2, under the effect of basket rod 4, fore-stock 1 and after-poppet 2 are gradually distance from along the longitudinal direction and launch, and after-poppet 2 rotates drivening rod 5 relative to push rod 3 and rotates, glide gradually thus ordering about sliding sleeve 6 along push rod 3, until when sliding sleeve 6 slides into switching place of push rod 3 and fore-stock 1, locking mechanism locks, and stroller frame is just in stable deployed condition.
Certainly, in technique scheme, sliding sleeve 6 also can be located on fore-stock 1 along the length bearing of trend of fore-stock 1 slidably, accordingly, one end of connecting rod 5 as drawing article is connected on sliding sleeve 6 rotationally, connecting rod 5 other end is connected on basket rod 4, in the expansion and folding process of stroller frame, connecting rod 5 can drive sliding sleeve 6 slide into the junction of push rod 3 and fore-stock 1 and then push rod 3 and fore-stock 1 are relatively fixed along with relatively launching of rod member each in stroller frame, push rod 3 and fore-stock 1 can be made can mutually to rotate and then make stroller frame folding along with pulling the sliding sleeve 6 junction from push rod 3 with fore-stock 1 to depart from when stroller frame folds simultaneously, this is equally reached Fig. 1 to the technique effect of embodiment illustrated in fig. 3 and result of use.
To sum up, the children trolley of the present invention, its rod member quantity is few, tailored appearance, and it is folding all very convenient with expansion operation, and the compact conformation after folding takes up room little.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this. All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
