Rack system

The guide rail is divided into multiple segments (first segment, second segment, third segment) with distinct functions. The first segment provides support, the second segment creates a passage for the fixing member, and the third segment offers additional support and blocking. This segmentation allows the assembly to maintain quick mounting capability while distributing and enhancing the load-bearing capacity across multiple structural zones.

The guide rail transitions from a simple linear structure to a three-dimensional configuration with extensions perpendicular to the main rail axis. The third segment includes first and second extensions that protrude in directions perpendicular to the longitudinal axis, creating multiple support planes and blocking surfaces. This dimensional enhancement significantly increases the load-bearing capacity while maintaining the rapid mounting function.

The guide rail integrates multiple functions into a single unified component. It combines support functions (first and third segments), guiding function (passage for fixing member in second segment), and blocking function (blocking portions) into one integrated structure. This merging approach enhances load-bearing capacity without proportionally increasing device complexity, as all these functions are accomplished within a single guide rail assembly rather than requiring separate components.

The guide rail serves multiple purposes simultaneously: it supports the chassis at multiple points, guides the fixing member during insertion, provides blocking to prevent over-insertion, and maintains alignment. This multi-functionality allows the structure to achieve high load-bearing capacity without adding numerous separate components, thereby limiting the increase in device complexity.
