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 ~ Fig. 4, comprise there is deployed condition and folded state stroller frame, be located at wheel assembly bottom stroller frame, for by stroller frame locking lockout mechanism in the deployed state.
Stroller frame comprises underframe 1, vertical rod 2, push rod 3, sliding part 4, first connecting rod 5 and second connecting rod 6, and the lower pivot of vertical rod 2 is connected to the middle part of underframe 1; The bottom of push rod 3 is connected with the top phase pivot of vertical rod 2; Sliding part 4 slides up and down to be located in vertical rod 2; The provided at one of first connecting rod 5 is connected on push rod 3, and its other end is pivotally connected on sliding part 4; The provided at one of second connecting rod 6 is connected to the rear portion of underframe 1, and its other end is pivotally connected on sliding part 4.Like this, push rod 3, vertical rod 2, between sliding part 4 and first connecting rod 5, just form a slider-crank mechanism, underframe 1, vertical rod 2, between sliding part 4 and second connecting rod 6, also form a slider-crank mechanism.
Concrete, shown in each accompanying drawing, in the present embodiment:
Underframe 1 comprises in the left and right sides and two front struts 11 being connected of leading section and the rear pole 12, two be connected between two front strut 11 rearward end form an approximate isosceles triangular structure between front strut 11 and rear pole 12.The middle part of two front struts 11 is all installed with the connector 13 extended outside underframe 1.
Vertical rod 2 comprises two poles 21 laying respectively at the left and right sides, and the bottom of the pole 21 of both sides is pivotally connected on the connector 13 on corresponding side front strut 11 respectively, and underframe 1 can front and back upset relatively to make vertical rod 2.Be permanently connected between the upper end of both sides pole 21 cross bar 22, and this cross bar 22 to be mainly used in stroller frame cross-tie to improve the rigidity of go-cart.
Push rod 3 comprises two pulling handle rods 31 laying respectively at the left and right sides and the handle 32 being fixedly arranged on both sides pulling handle rod 31 upper end, downward opening U-shaped is formed between the pulling handle rod 31 of handle 32 and both sides, on every side of stroller frame, the bottom of pulling handle rod 31 is connected with the top phase pivot of the pole 21 of this side; Pulling handle rod 31 is installed with a pocket interface 9, to facilitate mount pad pocket for children's sitting.Cross bar 22 also can be located between the pulling handle rod 31 of both sides, and in the present embodiment, the upper end of the end of cross bar 22 and the lower end of pulling handle rod 31, pole 21 is connected to same position place.Sliding part 4 adopts sliding sleeve, and this sliding sleeve can slide up and down to be set on pole 21.
On every side of stroller frame, the bottom of first connecting rod 5, the top of second connecting rod 6 are connected with sliding part 4 phase pivot by same rotating shaft, the upper pivot of first connecting rod 5 is connected on this thruster barre 31, and the lower pivot of second connecting rod 6 is connected to the rear portion of this side front strut 11.
Wheel assembly comprises the front-wheel 7 being located at underframe 1 front lower portion and two trailing wheels 8 being located at underframe 1 rear end two side lower part respectively.
When stroller frame is launched, by push rod 3, vertical rod 2, between sliding part 4 and first connecting rod 5, the slider-crank mechanism of formation locks, or by underframe 1, vertical rod 2, between sliding part 4 and second connecting rod 6, the slider-crank mechanism of formation locks, just these two slider-crank mechanisms can be made all to lock, and then stroller frame can be locked.In the present embodiment, lockout mechanism is arranged at for both being locked between vertical rod 2 and sliding part 4, that is this lockout mechanism is located between the pole 21 of both sides and sliding sleeve for sliding sleeve is locked in pole 21.When lockout mechanism locks, two above-mentioned slider-crank mechanisms are all locked and make between each rod member of stroller frame relatively fixing.
When this stroller frame is in expanded position, as depicted in figs. 1 and 2, lockout mechanism locks, the top of underframe 1 is stood in vertical rod 2 support, on every side of stroller frame, form a triangular structure between front strut 11, pole 21 and second connecting rod 6, between pole 21, pulling handle rod 31 and first connecting rod 5, also form a triangular structure, under stroller frame is stably in deployed condition, and stroller frame has good rigidity in the folded-out situation.When arranging, stroller frame when deployed condition, vertical rod 2 can be made vertically to distribute support and stand on underframe 1, stroller frame rigidity in the deployed state can not only be improved further like this, and make the outward appearance of stroller frame more graceful.
When stroller frame is folded up by needs, as shown in Figure 3, first lockout mechanism is unlocked, press down the rear portion of push rod 3, push rod 3 is turned over, this makes vertical rod 2 overturn forward simultaneously, drive sliding part 4 in vertical rod 2 along the short transverse slide downward of vertical rod 2, drive in the process of sliding part 4 slide downward first connecting rod 5 and second connecting rod 6 respectively relative vertical rod 2 overturn, and then make push rod 3, vertical rod 2, first connecting rod 5 and second connecting rod 6 are drawn close to underframe 1 gradually along the short transverse of stroller frame, finally be folded to form structure as shown in Figure 4, each rod member in stroller frame is all closely drawn close together.In the folding process of stroller frame, front-wheel 7 and trailing wheel 8 land all the time, make folding convenient.After folding, in vertical rod 2, the pole 21 of both sides lays respectively at the both sides of underframe 1 front portion, and cross bar 22 is positioned at the front of underframe 1, the stroller frame compact conformation after folding, highly low, takes up room little, conveniently deposits and carry.
When this stroller frame is launched to use by needs, lift push rod 3, its relative vertical rod 2 is overturn, turn over after ordering about vertical rod 2, this drives sliding part 4 along vertical rod 2 upward sliding, drives first connecting rod 5 and the relative vertical rod 2 of second connecting rod 6 to overturn, each rod member of stroller frame is launched gradually in the process of sliding part 4 upward sliding, until after stroller frame launches completely, lockout mechanism locks.
To sum up, children trolley of the present utility model, its structure is very simple, and rod member quantity is few, and tailored appearance is generous, it has stronger rigidity and stationarity in the deployed state, folding and expansion operates all very light, and the compact conformation after stroller frame folds is highly low, volume is little, is easy to carry about with one and deposits.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
