Description

  The present invention relates to a kind of interlocking localization structure for extending a slide rail. In particular, a kind of middle rail and inner rail are simultaneously stretched from the outer rail, and after positioning the outer rail relative to each other in the middle rail, the inner rail and middle rail are unlocked, and the inner rail is completely stretched independently, The present invention relates to a slide rail extension interlocking localization structure in which an inner rail and a middle rail are sequentially housed in an outer rail.

  In general, the basic structure of the telescopic slide rail used for a drawer or similar hook is a two-stage system composed of an inner rail and an outer rail, or a three-stage system composed of an inner rail, a middle rail and an outer rail.
