ABSTRACT:
A hidden type sliding rail assembly auto locking structure for drawer is disclosed comprised of a holder base, a slide, a coil spring member, a hook, a steel spring strip, a locking block, and an actuating block. When the outer sliding rail is moved outwards with the drawer, the actuating block pushes the steel spring strip to force the hook against the slide and to further force the locking block into a side notch and stopped at a stop edge at the holder base to prevent disconnection of the locking block, for enabling the coil spring member to return the drawer to the close position. Except the coil spring member, the holder base holds the other parts on the inside and keeps them from sight without the use of a cover, thereby saving much installation labor and time.
