The push handle telescopic folding structure comprises a lower vehicle frame, a telescopic push handle rotationally connected to the lower vehicle frame and a vehicle frame locking mechanism arranged between the lower vehicle frame and the telescopic push handle, and the telescopic push handle comprises a grip and a push rod; the frame locking mechanism comprises a spring bolt which is arranged at the lower part of the push rod and can slide relative to the push rod, and a locked part which is arranged on the lower frame and can be locked by the spring bolt, an unlocking hook which can move relative to the grip is arranged at the lower part of the grip, and the unlocking hook can be driven to move by an unlocking assembly on the grip; when the telescopic push handle is contracted to the shortest state, the unlocking hook hooks the to-be-hooked portion corresponding to the spring bolt, at the moment, the unlocking hook and the spring bolt can be driven to move synchronously through unlocking operation of the unlocking assembly to retreat from the locked portion of the lower frame, and unlocking of the frame is achieved. The bicycle frame unlocking device is novel in structure, unlocking of the bicycle frame can be achieved only when the telescopic push handle retracts to the shortest state, accidental unlocking of the bicycle frame caused by misoperation in the using process is avoided, and the using safety performance is greatly improved.

    本发明公开了一种童车的推把伸缩折叠结构,包括下车架、转动连接在下车架上的伸缩推把以及设置在两者间的车架锁定机构,所述伸缩推把包括握把及推杆;车架锁定机构包括设置在推杆下部且可相对其滑动的锁舌、设置在下车架上且可由锁舌锁定的被锁部,握把下部设有可相对其活动的解锁钩,该解锁钩可由握把上的解锁组件带动运动;当伸缩推把收缩至最短状态时,该解锁钩勾住锁舌对应的待钩部,此时通过解锁组件的解锁操作即可带动解锁钩及锁舌同步运动而退出下车架的被锁部,实现车架的解锁;本发明结构新颖,仅在伸缩推把缩至最短状态时,才可实现车架的解锁,避免了使用过程中因误操作而导致车架意外解锁,大大提高了使用的安全性能。
