Description

Technical Field

[0001] The utility model relates to the technical field of baby rocking chairs, in particular to a baby rocking chair with safe unlocking. Background Art

[0002] When the baby is in an uneasy state, the baby's relatives can rock the baby rocking chair to make the baby feel safe and comfortable, which has a good soothing effect.

[0003] A Chinese patent with patent number CN201220736568.6 discloses a baby rocking chair, which includes a base and a swaddling seat located above the base. The baby rocking chair has an open state and a folded state. The front part of the base has a support portion extending backward and obliquely upward. A first rotating shaft is pivotally connected to the support portion. When the rocking chair is unfolded on a horizontal plane, the axis of the first rotating shaft is inclined to the horizontal plane. A horizontally arranged second rotating shaft is pivotally connected to the lower part of the swaddling seat. The first rotating shaft and the second rotating shaft are pivotally connected. When the baby rocking chair is in the open state, the swaddling seat has a seat pocket opening facing forward and upward, the support portion abuts against the bottom surface of the swaddling seat and supports the swaddling seat. When the baby rocking chair is in the folded state, the swaddling seat rotates around the first rotating shaft and the second rotating shaft until the seat pocket opening of the swaddling seat faces the base. However, the baby rocking chair lacks a safety locking structure to protect the baby. During use, it is easy to accidentally unlock the chair, causing the angle between the base and the swaddling seat to change too much in an instant, exceeding the safe adjustment range of the angle, which can easily put the baby riding in the baby rocking chair in danger and the baby's safety cannot be guaranteed.
