The utility model relates to a rotating guardrail structure of a hospital bed, which comprises an outer frame, a positioning component, a stop pin, a stop spring, a button bracket and a button. The outer frame and the positioning component are combined and can rotate relatively, the inner end of the button is fixed with the outer end of the button bracket, the outer end of the button bracket extends out of the outer frame, the middle gap of the button bracket is penetrated in the middle hole of the outer frame and the positioning component, and the inner end of the button bracket and the annular convex in the middle of the stop pin The table is supported on the top, and the clearance between the outer end of the stop pin is successively set in the pin hole of the outer frame and the pin hole of the positioning assembly, and the stop spring is set between the inner end of the stop pin and the positioning assembly.Because the outer frame is close to the positioning assembly, a stop pin, a stop spring and a button bracket are arranged between the outer frame and the positioning assembly. By pressing the button, the button bracket and the stop pin can be driven to move, so that the outer frame and the positioning assembly can rotate relatively, the system structure is simple, the operation is convenient and easy to turn over.一種病床的旋轉護欄結構，包括：外框、定位組件、擋位銷、擋位彈簧、按鈕架及按鈕，外框與定位組件相靠合並可相對轉動，按鈕內端與按鈕架外端相固定，按鈕外端伸出外框，按鈕架中部間隙穿設在外框和定位組件的中孔內，按鈕架內端與擋位銷中部的環形凸台頂靠，擋位銷外端間隙依次穿設在外框銷孔和定位組件銷孔內，擋位彈簧設置在擋位銷內端與定位組件間。由於外框與定位組件相靠合，在外框與定位組件之間設置擋位銷、擋位彈簧及按鈕架，藉按壓按鈕可驅動按鈕架及擋位銷動作，使外框與定位組件可相對轉動，係結構簡單、操作方便且易於翻轉。
