Sliding rail structure for drawer of layered frame

A sliding rail structure disposing a bracket drawer in a layered frame, the sliding rail structure comprising a sliding rail plate buckled to one of two horizontal rods respectively arranged at two sides of the layered frame, thereby forming a sliding rail for the bracket drawer, wherein:

• the sliding rail plate is formed as a single metal piece that is punched for formation, so that a main body thereof is formed as a U-shaped slot rack,
• locations defined at a front end and a rear end of the U-shaped slot rack are respectively punched to form a vertical stop plate which is used as a pushing and pulling limitation for the bracket drawer,
• two predetermined locations at a front end and a rear end of a top edge defined at a solid side of the U-shaped slot rack are punched to form a pair of buckle hooks,
• buckle slots of the buckle hooks are in a non-arched polygonal configuration with respect to the horizontal rod,
• a base part of a main body of each of the buckle hooks is formed with a planar connecting surface to provide a structural reinforcing effect, and
• when the sliding rail plate is buckled to the horizontal rod, interfacing portions of the planar connecting surfaces and the buckle hooks are abutted against the horizontal rod, thereby obtaining enhanced abutting strength and enhancing stability of the sliding rail plate.
