Abstract
The utility model discloses an unlocking mechanism of a baby stroller. The unlock mechanism of the baby stroller comprises a shell body, a rotating member which is connected in the shell body in a pin point mode and a two way lock sliding member. The two way lock sliding member is matched with the shell body. A handle knob which extends out of the shell is formed on one side of the rotating member. An opening is formed in the shell in order to enable the handle knob to rotate. A pulling cable is connected between the rotating member and a locking mechanism of a stroller frame. The two way lock sliding member comprises an operation part which is placed on the outer wall of the shell and a lock part which is placed in the shell. A fixture block which corresponds to a clamping groove is arranged on one side of the lock part. A spring is arranged between the other side of the lock part and a fixed block of the shell. Due to the fact that the handle knob drives the rotating member to move, thereby pulling the pulling cable, the unlocking mechanism of the baby stroller achieves unlocking. When the stroller frame is unfolded, the rotating member is locked through the two way lock sliding member, unlocking caused by maloperation can be avoided, and safety of usage can be guaranteed.
