[0003] The retractable baby rocking bed is an important product in the field of modern infant and toddler products, and its design core lies in how to balance the convenience of retraction and the safety of use. Currently, similar products on the market generally use a structure of pivot joints combined with locking components to achieve the retracting function. The locking mechanism mostly relies on a single direct action operation button, and users can release the locking state and complete the retraction by directly pressing or toggling the button.

[0004] This straightforward operation method brings convenience to the retraction steps, however, it also produces a huge safety hazard. Due to the single unlocking action and the absence of any anti misoperation barriers, this button is easily touched by users or other objects during transportation, shaking, or daily care, causing the unexpectedly sudden release of locking mechanism, resulting in the accidental retraction of the rocking bed frame and posing a serious threat to the safety of infants in the bed.
