The invention discloses a rotation limiting structure for a child seat supporting leg and a working method thereof.The rotation limiting structure comprises a supporting leg body, a connecting piece is arranged on one side of the upper end of the supporting leg body, a sliding rail is arranged on one side of the connecting piece, two connecting plates are arranged at one end of the sliding rail, and the sliding rail is rotationally connected with the connecting piece through the connecting plates; a sliding groove is formed in one side of the connecting plate, and a limiting clamping groove is formed in the other side of the connecting plate. A limiting hook plate and a limiting convex block which are arranged on the connecting piece are matched with a sliding groove, a limiting notch and a limiting clamping groove which are formed in the connecting plate, and the limiting hook plate and the limiting convex block are clamped into the limiting notch and the limiting clamping groove respectively by rotating the supporting leg body so as to limit rotation of the connecting piece; the purpose of rotating and limiting the supporting leg body is achieved, and the problem that an existing supporting leg structure possibly shakes and is unstable in use, and the safety of the child seat is affected is solved.
本发明公开了一种用于儿童座椅支撑腿的旋转限位结构及其工作方法,包括支撑腿主体,所述支撑腿主体上端的一侧设置有连接件,且连接件的一侧设置有滑轨,所述滑轨的一端设置有两个连接板,所述滑轨通过连接板与连接件转动连接,所述连接板的一侧设置有滑槽,所述连接板的另一侧设置有限位卡槽。本发明通过连接件上设置的限位钩板和限位凸块与连接板上设置的滑槽、限位槽口和限位卡槽相互配合,并通过旋转支撑腿主体,将限位钩板和限位凸块分别卡入限位槽口和限位卡槽内部,以限制连接件转动,达到对支撑腿主体进行旋转限位的目的,避免现有支撑腿结构在使用时可能出现晃动不稳,影响儿童座椅的安全性的问题。
