Through the design, when the rotating strip 6 rotates, the first convex column 11 and the second convex column 12 respectively act with the first strip-shaped sliding opening 601 and the second strip-shaped sliding opening 602 at the two ends of the rotating strip 6, so that the foot back plate 301 and the back backup plate 303 can respectively rotate around the two ends of the hip back plate 302, and the angle adjustment of the whole folding frame 3 is realized.

Two arc foot plates 13 are arranged at the center of the lower end of the outer side surface of each side plate 1, and the two arc foot plates 13 are arranged in mirror symmetry. The end parts of the two arc-shaped foot plates 13 which are close to each other are rotatably connected with the side plate 1, and the arc-shaped edges of the lower ends of the two arc-shaped foot plates 13 are connected with the arc-shaped edges of the lower end of the side plate 1. The outer side faces of the end parts, close to each other, of the two arc-shaped foot plates 13 are fixedly connected with gears 14, and the gears 14 on the two arc-shaped foot plates 13 are meshed with each other. When the gear is arranged specifically, the gear is an incomplete gear, and gear teeth on the two incomplete gears are meshed with each other. Insert on one of them arc sole 13 and gear 14 and be equipped with second bolt 15, the surface lower extreme of curb plate 1 has been seted up a plurality of and second bolt 15 matched with second bolt hole 104, and the second bolt hole is provided with 4~6 during concrete setting to a plurality of second bolt hole 104 also sets up on same ring line, at arc sole 13 pivoted in-process promptly, in its second bolt 15 also can insert the second bolt hole 104 of corresponding position, thereby it is fixed with two arc soles 13. Be located and be connected with horizontal pole 16 between the outer tip of two front and back arc sole 13 of same side, rotate on the horizontal pole 16 and be provided with a plurality of gyro wheels 17, the gyro wheel 17 that sets up on its horizontal pole 16 is two when specifically setting up to two gyro wheels 17 are symmetrical setting from beginning to end.

In addition, wear-resisting layers (not shown in the figure) are arranged on the lower surfaces of the side plates 1 and the lower surfaces of the arc foot plates 13, and when the baby stroller is used as a swing bed, the wear-resisting layers can increase the wear resistance of the baby stroller when the baby stroller is in contact with the ground.

Finally, the first bolt 10 and the second bolt 15 in the present invention are both reset bolts, which are conventional and not shown in the drawings, and specifically, when the present invention is arranged, the outer ends of the first bolt 10 and the second bolt 15 are both connected with end blocks, the inner side surfaces of the end blocks are connected with springs, the inner ends of the springs on the first bolt 10 are connected with the outer surface of the side plate 1, and the inner ends of the springs on the second bolt 15 are connected with the outer surface of the gear 14.

The invention discloses a child stroller capable of switching states, which comprises the following use method and structural principles:

when the stroller disclosed by the invention is used as a stroller, the hand wheel 8 is rotated, the hand wheel 8 is fixedly connected with the rotating bar 6, so that the rotating bar 6 rotates in the inner cavity of the side plate 1, the second convex columns 12 and the second convex columns 12 on the foot back plate 301 and the back backup plate 303 of the rotating bar 6 are respectively matched with the second strip-shaped sliding opening 602 and the first strip-shaped sliding opening 602 at the two ends of the rotating bar 6 in the rotating process of the rotating bar 6, so that the foot back plate 301 and the back backup plate 303 rotate simultaneously to enable the whole folding frame 3 to form a posture as shown in figure 5, the first bolt 10 is inserted into the first bolt hole 101 on the side plate 1 to be fixed after adjustment is completed, and the whole folding frame 3 is chair-shaped, so that the stroller can be used.

When the folding frame is used as a child pushing bed capable of pushing to run, the hand wheel 8 can be rotated, and then the foot back plate 301, the hip back plate 302 and the back backup plate 303 are in the same horizontal position through the transmission action of the mechanisms, so that a child can sleep in the whole folding frame 3, and the whole device is still easy to push to run in the process of sleeping of the child.

Finally, when the stroller is used as a cradle, the second pin 15 is pulled out in the second state, one of the arc-shaped foot plates 13 is rotated, the two arc-shaped foot plates 13 are simultaneously rotated to be connected with the arc-shaped surface at the lower end of the side plate 1 through meshing transmission between the two gears 14, then the second pin 15 is inserted into the corresponding second pin hole to be fixed, the whole stroller is arranged into a cradle, a child is placed in the folding frame 3, and then the stroller is gently shaken to enable the child to fall asleep quickly.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
