The invention relates to a pipe fitting telescoping mechanism and a baby carriage. The pipe fitting telescoping mechanism comprises an outer pipe; the inner pipe is sleeved in the outer pipe in an axial moving manner; the locking device comprises a locking piece and a traction piece which are arranged in the inner pipe, and the locking piece is operably connected with the traction piece; the locking piece has a locking state for limiting the axial movement of the inner pipe relative to the outer pipe and an unlocking state for allowing the axial movement of the inner pipe; when the traction piece moves under the action of traction force, the locking piece is driven to be switched from the locking state to the unlocking state; and when the traction force is withdrawn, the locking piece has a trend of returning to the locking state from the unlocking state.

    本发明涉及一种管件伸缩机构及婴儿车。该管件伸缩机构包括:外管;内管,可轴向移动地套设在所述外管中;锁定装置,包括设置在所述内管中的锁定件和牵引件,所述锁定件与所述牵引件可操作地连接;其中,所述锁定件具有限制所述内管相对于所述外管做轴向移动的锁定状态和允许所述内管做所述轴向移动的释锁状态;所述牵引件在牵引力的作用下运动时,驱动所述锁定件从所述锁定状态切换到所述释锁状态;当所述牵引力撤销时,所述锁定件具有从所述释锁状态回复到所述锁定状态的趋势。
