摘要： A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

摘要： An anti-rollover structure, applicable to the cot body, includes at least two fixing elements and at least two support elements. The fixing elements are adapted to be mounted on an outer bottom surface of the cot body. The support elements are rotatably disposed at the fixing elements respectively. When the support elements are on a support surface, the support elements are subjected to pressure from the cot body and thereby rotated to protrude protruded from the cot body. A carrying device and a baby carrier are further introduced. The carrying device and the baby carrier each have the anti-rollover structure.

摘要： An anti-rollover structure, applicable to the cot body, includes a fixing element and a support element. The fixing element is adapted to be mounted on the outer bottom surface of the cot body. The support element is movably disposed at the fixing element and subjected to pressure from the cot body and thus protrudes from the cot body. The anti-rollover structure is structurally simple and easy to use. A carrying device and a baby carrier are further introduced. The carrying device and the baby carrier each have the anti-rollover structure.
