Description

Detent and rotation controls for main load bearing parts and mounts and children's vehicles

technical field

The invention relates to a children's carrier and its main bearing part control mechanism, in particular to a stop and rotation control device for the main bearing part and mounting parts and the children's carrier.

Background technique

The children's vehicle includes a main load-bearing part and a leaning part. The frame body has mounting parts. Both sides of the main load-bearing part have side plates. The side plates are installed on the mounting parts. The leaning part is connected to the main load-bearing part in a hinged manner for easy rotation. Adjust the leaning part.

Existing side panels are usually installed on the mounting parts with mounting shafts. After installation, the side panels cannot rotate around the mounting shafts, that is, the side panels cannot rotate relative to the mounting parts. As a result, the folded volume of the children's vehicle is still relatively large.

The folded volume of the children's carrier directly affects the storage space, especially during the transportation of the children's carrier. If the folded volume of the children's carrier can be further reduced, the storage space can be saved and the carrying capacity of the children's carrier can be increased. Reduce shipping costs.

The final folded structure of the child carrier is shown in FIG. 20 .

When the children's vehicle is unfolded, the operator drives the peg 53 engaging the iron support 5 to reversely rotate in the circumferential direction through the operating unit, and the external force exerted by the peg 53 on the sliding plastic block 11 is eliminated. Under the action of the elastic restoring force of the bit spring 12, it also reversely rotates along the circumferential direction. At this time, the leaning part of the child carrier can be stretched backward, and the sliding plastic block 11 reversely rotates along the circumferential direction. When the sliding plastic block 11 rotates to a wedge shape When the groove 11 is aligned with the wedge-shaped protrusion 232 of the linkage block 23 , the linkage spring 24 pushes the linkage block 23 to move in the opposite direction along the length direction of the accommodation groove 82 , and the wedge-shaped protrusion 232 of the linkage block 23 is positioned at the edge of the sliding plastic block 11 again. In the wedge-shaped groove 11, the rounded concave surface 231 intersects with the shaft hole 81 at this time, and the side plate 8 is converted from a rotational position relative to the mounting part 22 to a stop position as shown in FIG. 1 again.
