The invention provides a supporting leg structure and a child safety seat, the supporting leg structure comprises an inner pipe and an outer pipe, an adjusting plug is mounted between the inner pipe and the outer pipe, a connecting part of the adjusting plug is fixedly connected with the outer pipe, and a body is movably connected with the connecting part; and the body is connected with a gear assembly, a state indicating part is arranged on the side wall of the body, when the outer pipe and the inner pipe are mutually locked and the supporting legs are in a stressed supporting state, the inner pipe pushes the body to move upwards so as to show a first indicating window, and when the supporting legs are in a non-supporting state, the body moves downwards under the action of self gravity so as to show a second indicating window. The adjusting plug is designed to be of a structure with the body and the connecting part which are movably connected with each other, so that the body provided with the state indicating part can move up and down relative to the outer pipe, the second indicating window is displayed through the gravity effect of the body, and the first indicating window is displayed through the space allowance between the outer pipe and the inner pipe; and the condition that the supporting legs are installed in place is reliably and effectively prompted, and the overall structure is simple.
本发明提供了一种支撑腿结构及儿童安全座椅,支撑腿结构包括内管和外管,内管与外管之间安装有调节塞,调节塞的连接部与外管固定连接,本体与连接部活动连接;本体连接有档位组件,本体的侧壁设有状态指示部,当外管和内管相互锁定且支撑腿处于受力支撑状态时,内管推动本体上移以展示出第一指示窗,当支撑腿处于非支撑状态时,本体受自身重力作用下移以展示出第二指示窗。本发明中将调节塞设计为相互活动连接的本体和连接部的结构,使得设置有状态指示部的本体能相对于外管进行上下移动,并利用本体本身的重力作用展示出第二指示窗,利用外管与内管之间的空间余量展示出第一指示窗,保证可靠有效地提示支撑腿安装到位情况,整体结构也简单。
