Background

The existing three-section ball sliding rail generally comprises a shell, a middle rail and a rail core, wherein the middle rail is arranged in the shell and can slide, the middle rail can be pulled out from the shell, the rail core is arranged on the middle rail and can slide, the rail core can be pulled out from the middle rail, and the server case, a drawer and other structures are arranged on the rail core. In practical application, the shell is fixed on a vertical column or a cabinet body for installing a server case, when the sliding rail is unfolded, the unfolding and sliding sequence of the middle rail and the rail core is uncertain, the middle rail is unfolded in a sliding mode after the middle rail is unfolded completely (namely the middle rail is already slid to a gear and cannot slide forwards any more), the middle rail is unfolded in a sliding mode after the rail core is unfolded completely, the rail core is unfolded in a following mode when the middle rail is unfolded to a part, the middle rail is unfolded in a following mode when the rail core is unfolded to a part in a sliding mode, and the sliding unfolding sequence of the middle rail and the rail core is random and uncertain. And the width of shell is greater than the well rail, and the width of well rail is greater than the rail core, and that is to say, the rail core is the weakest structure of bearing capacity among the slide rail structure, therefore, when the rail core is connected with server machine case (under the condition of rail core bearing), if after the rail core is fully expanded or partly expanded, well rail begins to expand again, its sliding distance is big when the rail core is alone bearing, and the bearing time of rail core is longer, leads to the deformation degree great, seriously influences the life of slide rail.
