1. An aluminum extruded server slide rail, installed in a server cabinet, and coupled to two sides of a server, for a stretching operation or a retracting operation, wherein an interior of the server cabinet is provided with four vertical brackets, and two sides of the server are provided with a plurality of fixed columns, the aluminum extruded server slide rail comprising:
an inner rail, being a long strip structure manufactured by an aluminum extrusion process, and having a cross-sectional view in a c-shape, and upper and lower edges of the inner rail being formed with a first groove, a planar area of the inner rail being provided with a plurality of fixing holes corresponding to the plurality of fixed columns respectively, a rear section of the planar area of the inner rail being provided with a first operating hole configured to be corresponsive to a pair of fixing holes among the plurality of fixing holes;
a middle rail, being a long strip structure manufactured by the aluminum extrusion process, and having a cross-sectional view in a c-shape, and an interior of upper and lower edges of the middle rail being formed with a second groove, and an exterior of the upper and lower edges of the middle rail being formed with a third groove, the inner rail being spaced inside the middle rail, such that a first sliding assistance space is defined between the first groove and the second groove, a central part of the middle rail having a stock thickness greater than a stock thickness of a bilateral part, wherein the stock thickness of the central part cannot exceed two times of the stock thickness of the bilateral part, and a front section of a planar area of the middle rail being provided with a second operating hole;
an outer rail, being a long strip structure manufactured by the aluminum extrusion process, and having a cross-sectional view in a c-shape, and an interior of upper and lower edges of the outer rail being formed with a fourth groove, and the middle rail being spaced inside the outer rail, such that a second sliding assistance space is defined between the third groove and the fourth groove;
a plurality of sliding assistance parts, disposed in the first sliding assistance space and the second sliding assistance space respectively, such that the inner rail is slidable and telescope-able relative to the middle rail, and the middle rail is slidable and telescope-able relative to the outer rail; and
an elastic locking plate, with a central part fixed onto the inner rail, and two ends of the elastic locking plate being provided with a first locking part and a second locking part respectively, the first locking part being flatly installed and configured to be corresponsive to the first operating hole, such that the first locking part is locked at a position of the plurality of fixed columns that extend out from the pair of fixing holes on sides of the first operating hole, so as to fix the server onto the inner rail, the second locking part being tilted at a position corresponding to the second operating hole, and the second locking part being extended out from the second operating hole to form a linkage between the inner rail and the middle rail.
