The invention relates to the field of baby carriages, in particular to a handle telescopic linkage mechanism. The height adjusting device is used for adjusting the height of the handlebar of the baby carriage and comprises a lower handlebar, an upper handlebar and a locking mechanism, the upper handlebar is slidably mounted in the lower handlebar, the locking mechanism is used for locking the upper handlebar in the lower handlebar or releasing the upper handlebar from the lower handlebar, and the locking mechanism comprises a locking rod erected in the lower handlebar and a lock cylinder seat capable of reciprocating relative to the locking rod. The lock cylinder seat is fixedly connected with the upper handle, a telescopic spring bolt is arranged on the lock cylinder seat, a plurality of clamping grooves capable of clamping the spring bolt are formed in the lock rod, when the spring bolt is clamped in the clamping grooves, the upper handle is locked in the lower handle, and when the spring bolt is located outside the clamping grooves, the upper handle can slide in the lower handle. According to the linkage mechanism, the built-in lock rod is adopted, compared with a groove formed in the wall of the handle or an external lock rod in the prior art, the built-in lock rod can prevent the spring bolt from being collided and retracted by external force, safety is improved, and the whole is more attractive.

    本发明涉及本发明涉及婴儿车领域,特别涉及一种手把伸缩联动机构。用于调整婴儿车手把的高低,包括下手把、上手把和锁合机构,上手把可滑动安装在下手把中,锁合机构用于将上手把锁定在下手把中或者将上手把从下手把中释放,锁合机构包括架设于下手把中的锁杆和可相对于锁杆往复运动的锁芯座,锁芯座与上手把固定连接,锁芯座上设有可伸缩的锁舌,锁杆上设有若干个能够卡住锁舌的卡槽,当锁舌卡于卡槽内时,上手把锁定于下手把中,当锁舌处于卡槽外时,上手把可在下手把中滑动。本发明中的联动机构采用内置的锁杆,与现有技术中手把壁上开槽或外置的锁杆相比,内置锁杆可以避免锁舌受外力碰撞缩回,提高了安全性,也使整体更美观。
