[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a parent-child swing device with the following beneficial effects:

[0015] 1. The restraint strap design, with its multi-position locking holes and levers, combined with the double-locking design of the top plate, significantly improves the stability and safety of children riding in the swing. After passing through the backrest slot, the restraint strap can be inserted into the locking holes at different positions by the lever, flexibly adapting to the fixation needs of children of different sizes; the locking groove at the end of the plate further engages with the locking ring on the backrest, forming a redundant lock, effectively preventing accidental disengagement and avoiding children slipping or leaning forward while swinging, especially suitable for active young children.

[0016] 2. The T-shaped handrail design, with its symmetrical arrangement and bottom connecting rod, forms a U-shaped protective frame, providing children with lateral, wraparound protection. The handrail extends through the sub-panel, creating a physical barrier that restricts the child's lateral movement; the bottom connecting rod enhances the overall structural rigidity while facilitating synchronized adjustments. This design effectively reduces the risk of children tipping over during swaying, while providing a gripping point for toddlers, enhancing their sense of security and self-balancing ability while riding.

[0017] 3. The locking mechanism, through a rotating locking ring and spring-loaded limit rod, allows for quick, one-handed adjustment and secure locking of the handrail height. Pressing down the limit rod releases the locking ring from the handrail's locking groove, facilitating height adjustment by sliding up and down. After release, the spring automatically returns to its original position, the limit rod inserts into the sub-plate's limit hole, and the locking ring simultaneously engages the handrail, ensuring stability through double locking. This mechanism eliminates the cumbersome operation of traditional bolt tools, significantly improving ease of use and meeting the immediate adjustment needs of children of different ages.
