[0034] The working principle of this embodiment is as follows: The present invention provides a safety rocking chair with a safety lock. When the rocking chair is converted from an unfolded state to a folded state, the pressing portion 511 of the safety lock 51 is first pressed to unlock the safety lock 51, and then the driving handle 41 of the driving mechanism 40 is pushed. The driving handle 41 drives the driving member 42 to rotate forward, and the driving surface 421 of the driving member 42 applies a driving force to the reverse driving surface 537 of the elastic connecting rod locking member 53, so that the elastic connecting rod locking member 53 is disengaged and unlocked from the elastic connecting rod 13, and then the elastic connecting rod 13 drives the seat pipe frame 10 to fold downward and convert it to a folded state. After folding into place, the safety lock 51 re-locks the driving mechanism 40 under the action of the reset compression spring 52.

[0035] When the rocking chair is converted from the folded state to the unfolded state, the rocking chair can be unfolded without unlocking the safety lock again. Specifically, when the seat tube frame 10 is unfolded, the seat tube frame 10 drives the elastic connecting rod 13 to unfold upward, and the control section 135 of the elastic connecting rod 13 slides along the sliding push surface 535 of the elastic connecting rod locking member 53. When the control section 135 of the elastic connecting rod 13 slides to the bottom of the sliding push surface 535 of the elastic connecting rod locking member 53, the control section 135 of the elastic connecting rod 13 falls into the slot 533 of the elastic connecting rod locking member 53. After the elastic connecting rod 13 is unfolded to the right position, under the action of the return spring 54, the anti-driving surface 537 of the elastic connecting rod locking member 53 applies a driving force to the driving surface 421 of the driving member 42, thereby locking the elastic connecting rod 13 and converting it to the unfolded state. During the upward unfolding process of the elastic connecting rod 13, the safety lock 51 remains in a locked state, and in the unfolded state, the safety lock 51 is unlocked without pushing the driving mechanism 40 or the safety lock 51 remains locked to push the driving mechanism 40, and the safety rocking chair remains in the unfolded state. Only when the safety lock 51 is unlocked and the driving mechanism 40 is pushed can the safety rocking chair be folded.
