本发明公开一种婴儿推车及其伸缩把手组件,其中,伸缩把手组件包括固定套管、伸缩套管、滑动本体、第一滑动件及第二滑动件;固定套管沿轴向设有多个定位孔;伸缩套管与固定套管滑动套接;滑动本体固定在伸缩套管中,滑动本体上径向滑设适于伸出伸缩套管与定位孔配合的第一锁定件;第一滑动件上径向滑设与使支架保持打开状态的锁定机构连接的第二锁定件,第一滑动件被设置为滑动第一滑动件时,第二锁定件驱使锁定机构解锁;第二滑动件被设置为滑动第二滑动件时,联动第一锁定件脱离定位孔同时驱使第二锁定件与锁定机构断开连接。本发明在实现长度调节功能及支架折叠功能其中一种功能时,有效避免误触发而实现另一种功能,从而避免使用危险。

    Disclosed are a baby stroller and an extendable handle assembly thereof. The extendable handle assembly comprises a fixed sleeve, an extendable sleeve, a sliding body, a first sliding piece, and a second sliding piece; a plurality of positioning holes are formed in the axial direction on the fixed sleeve; the extendable sleeve is slidably sleeved within the fixed sleeve; the sliding body is fixed within the extendable sleeve, and a first locking piece used for extending out of the extendable sleeve and matching with a positioning hole is radially slidably arranged on the sliding body; a second locking piece connected to a locking mechanism causing a support frame to be kept in an open state is radially slidably arranged on the first sliding piece; when the first sliding piece is configured to slide the first sliding piece, the second locking piece drives the locking mechanism to unlock; and when the second sliding piece is configured to slide the second sliding piece, the first locking piece moves in a linked fashion to separate from the positioning hole while the second locking piece is simultaneously driven to disconnect from the locking mechanism. When the present invention realizes one function among a length adjustment function and a support frame folding function, the other function is effectively prevented from being accidentally triggered, and thereby a use risk is avoided.
