After the first locking mechanism is locked, the first portion 11 and the second portion 12 are relatively fixed, so that the first section 21 and the second section 22 are relatively fixed by the quadrilateral structure formed by the second side stop lever 32 and the fourth side stop lever 34, and the child carrier is ensured to be in the unfolded state. The first locking mechanism is unlocked and the child carrier is capable of folding.
On the basis of the second embodiment, a second locking mechanism is provided at the second hinge point 23 for holding the child carrier in the unfolded state. After the second locking mechanism is locked, the first section 21 and the second section 22 are relatively fixed, so that the first part 11 and the second part 12 are relatively fixed by the quadrilateral structure formed by the second side stop lever 32 and the fourth side stop lever 34, and the child carrier is ensured to be in the unfolding state. The second locking mechanism is unlocked and the child carrier is capable of folding.
On the basis of the third embodiment, according to the joint where the first side bar 31 and the second side bar 32 are commonly hinged, the unfolding/folding of the child carrier can be achieved by providing a locking mechanism at the hinge point.
In one embodiment, the first side bar 31 or the third side bar 33 extends downward to form a first leg 35; the second side bar 32 or the fourth side bar 34 extends downwardly to form a second leg 36. The two support legs increase the ground clearance of the underframe 1, thereby being convenient for nursing. And the wheels can be arranged at the bottom, so that the outdoor or indoor movement is facilitated, and the anti-skid support seat (not shown) can be further extended downwards and added at the bottom.
