Embodiment

The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.

Referring to the children trolley shown in Fig. 1 to Fig. 6, it includes the stroller frame with deployed condition and folded state, set Wheel assembly in stroller frame bottom, and for the locking mechanism by stroller frame locking in the deployed state.Wherein, wheel group Part includes being divided into two groups of front components 10 of the anterior left and right sides in stroller frame bottom and is divided into stroller frame bottom rear portion or so Two groups of wheel assemblies 20 of both sides.

After the stroller frame includes from front to back the fore-stock 1 that gradually updip extends, gradually updip extends from back to front Support 2, the seat frame 3 extended along the longitudinal direction and the push rod 4 for tilting extension along the vertical direction, wherein, fore-stock 1 and rear branch Frame 2 intersect setting and infall phase pivot connection, the rear portion of seat frame 3 be connected with the top phase pivot of fore-stock 1 and The position of the rwo phase pivot connection is located at the rear of after-poppet 2；Push rod 4 is pivotally connected in the top of after-poppet 2, seat frame 3 Front portion be connected with the bottom phase pivot of push rod 4.So, constituted as above between fore-stock 1, after-poppet 2, seat frame 3 and push rod 4 Quadric chain, by the relative rotation of each rod member in the quadric chain cause stroller frame realize expansion and folding.

Locking mechanism can be the locking piece for above-mentioned quadric chain to be locked（Not shown in figure）, before it is arranged on It is used between at least two parts in this four parts of support 1, after-poppet 2, seat frame 3 and push rod 4 by this at least two Part is locked, and the locking piece just can realize the locking to stroller frame when locking.

In the present embodiment, each rod member/part specifically sets as follows in the stroller frame：

Referring to shown in Fig. 1 to Fig. 6, fore-stock 1 includes being located at the front support rod 11 of the left and right sides, two groups of front components 10 respectively It is respectively arranged on the bottom of both sides front support rod 11；After-poppet 2 includes being located at the back stay 21 of the left and right sides respectively, is fixedly connected on two Rear transverse rod 22 between the bottom of side back stay 21, two groups of wheel assemblies 20 are respectively arranged on the bottom of both sides back stay 21.

Seat frame 3 include respectively be located at the left and right sides and extend along the longitudinal direction seat bar 31, be fixedly connected on both sides Cross bar 32 between seat bar 31, herein, cross bar 32 are wholely set with the seat bar 31 of both sides and are in the U-shaped bar of opening backwards.Push rod 4 In downward opening U-shaped bar, it has the push rod side lever 41 for being located at the left and right sides respectively and tilting extension along the vertical direction.

On every side of the stroller frame left and right sides, front support rod 11 and back stay 21 intersect and in infall by the The phase pivot of one axle 5 is connected；Push rod side lever 41 is connected by the second axle 6 with the top phase pivot of back stay 21；The front portion of seat bar 31 It is connected by the 3rd axle 7 with the bottom phase pivot of push rod side lever 41；The rear portion of seat bar 31 passes through the upper of the 4th axle 8 and front support rod 11 Portion's phase pivot connection.Wherein the second axle 6 is located at the top of first axle 5 on back stay 21, and the 3rd axle 7 is upper in push rod side lever 41 In the lower section of the second axle 6, the 4th axle 8 is located at the top of first axle 5 on front support rod 11.

Referring to shown in each accompanying drawing, after-poppet 2 also includes the bar being fixedly provided between the top of both sides back stay 21 23, formed and accommodated when stroller frame is in deployed condition, between bar 23 and seat frame 3, the back stay 21 of both sides and push rod 4 The sitting space of children's sitting.During specific setting, also fore-stock 1, seat frame 3 and push rod 4 can be arranged on two in left-right direction Between the back stay 21 of side.

So, when stroller frame is locked in deployed condition, as shown in Figure 1 and Figure 2, fore-stock 1 and after-poppet 2 are along front and rear Direction is intersected expansion and provides seat frame 3 and supported with stable, is supported so as to provide children with stable sitting.

When needing to fold up stroller frame, push rod 4 is turned over after locking mechanism unblock.Referring to Fig. 3 Fig. 4 Shown, when push rod 4 is overturn with respect to after-poppet 2, the bottom of push rod 4 is common up with the front portion of seat frame 3, so that seat frame 3 overturn and drive fore-stock 1 to be rotated relative to after-poppet 2, and then make it that fore-stock 1, after-poppet 2, seat frame 3 and push rod 4 are mutual Draw in together, realize the folding of stroller frame.

Stroller frame after folding as shown in Figure 5, Figure 6, its structure very compact smooth, the bottom and both sides of push rod 4 Front component 10 and wheel assembly 20 be supported on ground jointly so that stroller frame is that the daily of user is taken from standing on ground Band is provided convenience with storage.

Above-described embodiment is only to illustrate technical concept of the present utility model and feature, and its object is to allow be familiar with technique Personage can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this. All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it It is interior.
