Rotary buckle type fixed slide rail structure

The utility model relates to a rotary buckle type fixed slide rail structure. An extension rod is combined and fixed on a locking plate, and both ends of the extension rod are respectively provided with side baffle plates. Snap sheets are riveted at the inner sides of the side baffle plates arranged on both ends. A through hole between each snap sheet and each side baffle plate can be used for arranging locking components, and fixing convex points are arranged nearby the through holes. Rotary buckles can be axially arranged at the through holes, and axis holes on rotary buckle bodies are eccentrically arranged. A finger cocking part is arranged at the edge of one side of each body. The rotary buckles can be penetrated into the axis holes by axis members, then are axially connected and positioned in the through holes, and are in a pivot state. As the rotary buckles generate a rotary buckle type fixed structure with a multiple-section type after the rotary buckles are eccentrically pivoted, a slide rail device can simultaneously be convenient for different box bodies to implement dragging actions.
