Abstract
The invention discloses a baby carriage. A baby carriage frame comprises a front bracket and a rear bracket which are crossed and are connected with each other at the intersection by a pivot shaft, and a push rod of which the lower part is connected with the upper part of the rear bracket by a pivot shaft, wherein the upper part of the front bracket and the push rod can slide relatively and are connected with each other in a manner of relative rotation; when the baby carriage frame is unfolded, the front bracket, the rear bracket and the push rod form a triangular structure; when the baby carriage frame is folded, the push rod is turned backwards, and the front bracket and the rear bracket get close to each other. According to the baby carriage, the number of rod pieces is small, and the structure is very simple; when being unfolded, the baby carriage frame is high in stability. When the baby carriage is folded and unfolded, only the push rod is needed to be turned over front and back, so that the operation is very convenient; the folded baby carriage is extremely compact in structure and occupies a smaller space, so that high comprehensive usability is achieved.

preferably, in the top of described front frame and these two parts of described push rod, one of them parts is provided with sliding part, and described sliding part is located on another parts slidably, and the relatively described front frame of described sliding part or described push rod are arranged rotationally.
further, described sliding part is be located at the sliding pin on described parts, and another described parts offer chute, and described sliding pin is plugged in described chute slidably.
further, described sliding pin is located on described push rod regularly, and described chute is opened in the top of described front frame, and described sliding pin slidably and can be plugged in rotationally in described chute around Pivot Point Center line.
preferably, described push rod has the connecting rod to downward-extension, between the bottom of described connecting rod and the top of described front frame can relative sliding be connected rotationally.
further, described push rod is fixedly provided with a pocket care frame, upper end and the described seat pocket care frame of described connecting rod are fixedly connected.
further, the pole portion that described front frame comprises from front to back updip gradually, the montant portion upwards extended from the upper end in described pole portion, described montant portion is connected with described push rod.
further, when described stroller frame is in deployed condition, described connecting rod and described montant portion extend along same length direction.
preferably, described lockout mechanism is located between described push rod and described front frame for both being locked.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: children trolley of the present invention, and its rod member quantity is few, and structure is very simple, and stroller frame has good stability upon deployment.Overturn push rod before and after only needing when go-cart being carried out folding and launch, operation convenience very, the cart structure after folding is also very compact, takes up room less, has good comprehensive in-use performance.

Detailed description of the invention
below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.
see the children trolley shown in Fig. 1 to Fig. 6, comprise there is deployed condition and folded state stroller frame, be located at wheel assembly bottom stroller frame, and for by stroller frame locking lockout mechanism in the deployed state.
this stroller frame comprises front frame 1, after poppet 2 and push rod 3, front frame 1 intersects with after poppet 2 and is connected at infall phase pivot, the bottom of push rod 3 is connected with the top phase pivot of after poppet 2, the top of front frame 1 with can relative sliding and being connected rotatably between push rod 3.
specifically can be connected in the following way between front frame 1 with push rod 3: in the top of front frame 1 and these two parts of push rod 3, one of them parts is provided with sliding part, this sliding part is located on another parts slidably, and the relative push rod 3 of this sliding part or front frame 1 are arranged rotationally.
in the present embodiment, the pole portion 11 that front frame 1 comprises from front to back updip gradually, the montant portion 12 upwards extended from the upper end in pole portion 11, after poppet 2 updip and intersect with pole portion 11 and be connected by the first axle 8 phase pivot gradually from back to front.Push rod 3 has the connecting rod 4 to downward-extension, by this connecting rod 4, the montant portion 12 with front frame 1 top is connected.Here, montant portion 12 offers the chute 6 extended along its length, the lower end of connecting rod 4 is provided with sliding pin 5 rotationally, and this sliding pin 5 is plugged in chute 6 slidably, and so just achieving between push rod 3 and the top of front frame 1 can relative sliding and to be relatively turnablely connected.Certainly, sliding pin 5 also can be located at the lower end of connecting rod 4 regularly, now, sliding pin 5 can be arranged in chute 6 rotationally around Pivot Point Center line.
shown in each accompanying drawing, the upper end of after poppet 2 is fixedly provided with attaching parts 10, and the rear end of this attaching parts 10 is connected by the second axle 9 phase pivot with the lower end of push rod 3.Push rod 3 is also fixedly provided with a pocket care frame 7, this pocket care frame 7 is fixedly connected with the upper end of connecting rod 4.Wheel assembly comprises the front-wheel 20 be located at bottom front frame 1 and the trailing wheel 30 be located at bottom after poppet 2.
lockout mechanism (not shown) is located at for both being locked between push rod 3 and front frame 1, and this lockout mechanism can be located between connecting rod 4 and montant portion 12 herein.
when stroller frame is launched, as shown in Figure 1 and Figure 2, lockout mechanism locks, and connecting rod 4 and montant portion 12 extend along same length direction, form triangular structure, under stroller frame is in stable deployed condition between front frame 1, after poppet 2 and push rod 3.When stroller frame folds by needs, first lockout mechanism is unlocked, then push rod 3 is turned over, make push rod 3 relative to after poppet 2 while the second axle 9 rotates, sliding pin 5 is along chute 6 slide downward and rotate relative to connecting rod 4, and order about front frame 1 and rotate around the first axle 8 relative to after poppet 2 and draw close gradually along the longitudinal direction, as shown in Figure 3, Figure 4.Finally, front frame 1, after poppet 2 and push rod 3 are drawn close together, form structure as shown in Figure 5, Figure 6.When stroller frame is launched by needs, above lift push rod 3.
to sum up, children trolley of the present invention, its rod member quantity is few, and structure is very simple, and folding and expansion operates all very convenient, and the structure after folding is also very compact, takes up room less.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
