SLIDE RAIL ASSEMBLY

摘要

A slide rail assembly (22) comprises a first rail (26), a second rail (28), a third rail (30), a blocking element (56) and an engagement element (46). The first rail (26) has a blocking part (36). The blocking element (56) is connected to the second rail (28). When the second rail (28) is located at a retrieve position relative to the first rail (26), and the engagement element (46) is operatively connected to the blocking element (56) for moving the blocking element (56) from a first predetermined position to a second predetermined position relative to the second rail (28), only the third rail (30) can move relative to the second rail (28) when the slide rail assembly (22) is extended along an extension direction, in order to adjust extension length of the slide rail assembly (22).
