Three-Frame Rail Supporting Device for Adjustable Rack Mounting Span

The bracket is divided into multiple independent frames (first frame, second frame, third frame) that can be segmented and arranged in sequence. Each frame has its own supporting sections that can independently bear loads, thereby extending the overall supporting span while maintaining manageable structural complexity through modular segmentation.

The frames are nested or interconnected in a hierarchical manner where the second frame is positioned between and supported by the first and third frames. This nested arrangement allows each frame to contribute to the overall supporting span while sharing structural loads, effectively extending the supporting span without proportionally increasing complexity.

The structural strength is enhanced by segmenting the bracket into multiple frames with individual supporting sections. Each frame acts as an independent load-bearing unit with its own stiffening ribs and supporting sections, distributing the structural stress across multiple points rather than concentrating it in a single bracket, thereby improving overall structural strength.

Multiple frames are combined or interconnected to form a unified supporting structure. The first, second, and third frames work together as an integrated system, where the combined structural strength of all frames provides enhanced support for the slide rail, overcoming the limitations of a single bracket while maintaining coordination among the components.

The bracket incorporates adjustable mounting mechanisms that allow the frames to be dynamically reconfigured for different rack depths. The mounting sections include adjustable fastening features and positioning elements that can be adapted to various mounting positions, enabling the same bracket structure to maintain precise mounting across different rack configurations rather than requiring fixed, depth-specific designs.

The bracket is designed as a universal mounting structure that can accommodate multiple rack depths and configurations. The frames include universal mounting sections with adjustable positioning capabilities, allowing the same bracket design to function across different rack types and depths while maintaining mounting precision through standardized adjustment mechanisms rather than requiring depth-specific custom designs.
