Referring to fig. 2, 3, 5 and 7, at least the th rod 1 or the second rod 2 is provided with a long slot 21 engaged with the connecting shaft 11, the connecting shaft 11 is slidably inserted into the long slot 21 along an extending direction of the long slot 21, the th rod 1 is provided with a th abutting portion, the second rod 2 is provided with a second abutting portion capable of abutting against the th abutting portion, the children products have an unfolded state, a folded state and a folded state, as shown in fig. 1 to 3, when the children products are in the unfolded state, the th rod 1 and the second rod 2 are relatively unfolded, the connecting shaft 11 is located at a 894 th position in the long slot 21, the th abutting portion and the second abutting portion abut against each other to prevent the connecting shaft 11 from sliding along the long slot 21, as shown in fig. 4 and 5, when the children products are in the th folded state, the th rod 1 and the second rod 2 are relatively moved closer to each other, the connecting shaft 11 is located at a th abutting portion in the long slot 21, the second abutting portion, the long slot is located at an angle, when the children products are moved to the second abutting portion, and the second abutting portion, the second abutting the long slot 2, when the connecting shaft 638 is located at an angle is smaller than the second abutting portion, when the connecting shaft 638, when the second abutting portion is located at the connecting shaft 638, and the connecting shaft 638 when the second abutting to the second pole 2, when the second abutting portion, when the connecting shaft 638 is located at an angle is smaller than the second.

In this embodiment, the connection shaft 11 is disposed on the th rod 1, the elongated slot 21 is opened on the second rod 2, and the elongated slot 21 extends along the length direction of the second rod 2, wherein the th rod 1 includes a rod-shaped body 1a and a joint 1b connected to the upper end of the rod-shaped body 1a, the second rod 2 includes a rod-shaped body 2a and a joint 2b connected to the upper end of the rod-shaped body 2a, here, the "length direction of the second rod" specifically refers to the length direction of the rod-shaped body 2a of the second rod 2, i.e., the extending direction of the rod-shaped body 2a, as indicated by an arrow L in fig. 2. the connection shaft 11 is disposed on the joint 2b, and the elongated slot 21 is opened on the joint 2 b. the elongated slot 21 has a second end and a second end opposite to each other, and the distance between the second end of the elongated slot 21 and the rod-shaped body 2a end is smaller than the distance between the th end of the rod-shaped body 2a end.the is specifically at the second end of the elongated slot 387 of the elongated slot, and when the connection shaft 21 is in the folded state, and when the second end of the connection shaft 11 is in the folded state.

The th contact part is a th contact surface 12 facing the rod-shaped body 2a and formed on the joint 1b of the th rod 1. the second contact part is a second contact surface 22 formed on the joint 2b of the second rod 2, the second contact surface 22 can be arranged opposite to and in contact fit with the th contact surface 12, and can prevent the connecting shaft 11 from sliding towards the second end part of the long groove 21 in the unfolded state.

The second rod 2 also has an arcuate surface 23 that abuts the second contact surface 22 or is adjacent to the second contact surface 22. the arcuate surface 23 may also be replaced by a ramped surface, by providing an arcuate surface 23 or ramped surface that prevents relative rotation of the th rod 1 and the second rod 2 when collapsed. the th rod 1 also has an arcuate surface 13 that abuts the th contact surface 12 or is adjacent to the th contact surface 12. the arcuate surface 13 may be replaced by a ramped surface. when the child article is in the extended position and collapsed positions, the arcuate surface 13 on the th rod 1 is opposite to and spaced from the arcuate surface 23 on the second rod 2. when the child article is in the second collapsed position, the arcuate surface 23 on the second rod 2 abuts the th contact surface 12 on the th rod 1 and is in touching engagement.

Referring to fig. 1, 4 and 6, the children's article further includes a push rod 5 and a connecting rod 6, the push rod 5 is rotatably connected to the th rod 1, the connecting rod 6 is rotatably connected to the push rod 5 and the second rod 2, respectively, and the rotation connection between the th rod 1 and the push rod 5 is located between the rotation connection between the th rod 1 and the second rod 2 and the rotation connection between the push rod 5 and the connecting rod 6 (as shown in fig. 1), the angle formed between the th rod 1 and the push rod 5 when the children's article is folded times is greater than the angle formed between the th rod 1 and the push rod 5 when the children's article is folded twice.

The child product is used as follows:

as shown in fig. 1 to 3, when the child product is in the unfolded state, the th rod 1 and the second rod 2 are unfolded relatively, the connecting shaft 11 is located at the th end of the long slot 21, while the second contact surface 22 on the second rod 2 and the th contact surface 12 on the th rod 1 are opposite and in abutting contact with each other, the th contact surface 12 provides a blocking function, that is, the th rod 1 and the second rod 2 are completely restrained under the action of the th contact surface 12 and the second contact surface 22, at this time, the connecting shaft 11 cannot slide towards the second end of the long slot 21, and thus the th rod 1 and the second rod 2 are stably unfolded;

when the children article is folded, the th rod 1 and the second rod 2 are rotated around the connecting shaft 11 to be close to each other, so that the children article is in a -time folded state as shown in fig. 4 and 5, at the moment, the connecting shaft 11 is still positioned at the th end of the long groove 21, the contact surface 12 and the second contact surface 22 are separated from each other, a space is reserved between the arc-shaped surface 13 and the arc-shaped surface 23, namely, the th rod 1 and the second rod 2 are in a semi-restrained state, and the connecting shaft 11 can slide along the long groove 21 after external force is applied;

and (3) continuously applying an external force F1 to the th rod 1 or an external force F2 to the second rod 2 along the direction indicated by an arrow, the second rod 2 continuously approaches the th rod 1, the connecting shaft 11 slides to the second end part of the long groove 21 along the long groove 21, and the children product is in a secondary folding state as shown in fig. 6 and 7, at the moment, the th rod 1 and the second rod 2 move further to approach, so that the folded volume of the children product is further .

It should also be noted that when the child article is in the unfolded position, folded position or the folded position, the bottom of each wheel is in the same plane . that is, during the unfolding and folding process, the front wheel 3 and the rear wheel 4 can both land and stand on the ground.

The above-mentioned embodiments are merely illustrative of the technical ideas and features of the present invention, and are preferred embodiments, so that those skilled in the art can understand the contents of the present invention and implement the present invention, and the protection scope of the present invention is not limited thereby. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
