Detailed ways

As shown in the accompanying drawings, a children's stroller includes a stroller frame 1 with an unfolded position and a folded position, a front wheel assembly 2, and a rear wheel assembly 3 for locking the stroller frame 1 in the unfolded position. The locking mechanism, the seat that is arranged on the stroller frame 1.

Cart frame 1 includes:

The front bracket 4, the front wheel assembly 2 is arranged on the lower part of the front bracket 4;

Rear bracket 5, the upper part of rear bracket 5 is pivotally connected with front bracket 4 through first rotating shaft 11, and rear wheel assembly 3 is arranged on the bottom of rear bracket 5;

The first sliding member 8, the first sliding member 8 can be slidably arranged on the rear support 5 along the up and down direction of the rear support 5;

Seat frame 6, the front portion of seat frame 6 is pivotally connected with front support 4 through the third rotating shaft 13, as shown in accompanying drawing 2, accompanying drawing 4, seat frame 6 and first slider 8 are connected through the 4th rotating shaft 14 pivot connection;
