Abstract

The utility model relates to a locating structure for bidirectional pull sliding rails, wherein, a paired conductive wall is arranged on the first rail and a position limiter is positioned on each end of the first rail. The position limiter has two upright walls and a groove is positioned between the two walls .A hook which stretches to one side is disposed at the groove projection of the position limiter. The first rail has more than one locating blocks and the locating block has a hook which stretches one side .The hook has the elasticity of being internal pressed and projecting out. The second rail is positioned between the two conductive walls of the first rail and a position limiter is disposed at each end of the second rail like in the case of the first rail. Each side of the position limiter is arranged with a wall and the inner side of one of the two walls forms a slant wall on a different flat surface. The slant wall together with the position limiter of the first rail and the hook arranged on the locating block forms a chiming or stopping location. Adopting the bidirectional pull sliding rails, when a drawer is pulled out, the utility model is capable of positioning the drawer and stops the drawer from slipping out.
