A slide rail structure for a window blind includes at least one extensible rail set, at least one pulley set, and a plurality of top brackets. The extensible rail set is provided with at least two slide rails which are loosely extended with respect to each other and are assembled together, and a side of each slide rail is provided with an open slot. The pulley set is loosely assembled in the slide rail of extensible rail set, and is extended out of the open slot at one side of each slide rail. A side of each top bracket is formed with an arc-shape locking part for sheathing the slide rail of extensible rail set, and a top of each top bracket is provided with a hole for locking and positioning. The slide rail structure can be easily and quickly assembled, can be rigidly positioned and can slide smoothly.
