Shelf supporting sliding rail

Abstract

The present invention relates to a shelf supporting sliding rail, including a sliding rail body. Protrusions and recessed portions distributed in an array in a length direction are arranged on a front surface of the sliding rail body. The protrusions and the recessed portions are arranged in a spaced manner, and the protrusions are in close connection to the recessed portions adjacent to the protrusions above to form a locking position where a shelf mounting buckle is locked. The depth of the locking position in a direction perpendicular to the front surface of the sliding rail body increases, to improve the locking stability and reliability of the shelf mounting buckle on the shelf supporting sliding rail, and further improve the bearing capacity.
