1. A geometric reinforcing structure for a slide rail, wherein the slide rail comprises an inner rail, a middle rail, an outer rail and a plurality of slip elements, and the slip elements are movably installed between the inner rail and the middle rail, and between the middle rail and the outer rail respectively, such that the inner rail and the middle rail can be sequentially pulled out and extended to the outside relative to the outer rail, characterized in that:
the middle rail comprises a plurality of reinforcing blocks, which have identical geometric figure, formed on a surface thereof by stamping, and equidistantly spaced and configured relative to each other along the extension direction of the middle rail, and a configuration means provided for forming an interference portion between two adjacent reinforcing blocks to improve load strength of pulling out, wherein
a number of the reinforcing blocks is greater than three, and in a plan view, in a direction vertical to a long side of the middle rail, each of the reinforcing blocks, other than a rightmost reinforcing block and a leftmost reinforcing block, comprises a first portion and a second portion, the first portion overlaps at least a part of an adjacent reinforcing block, and the second portion is overlapped by at least a part of another adjacent reinforcing block.
