Description

Technical Field

[0001] This utility model relates to the technical field of bracket rail structures, specifically a bracket rail. Background Technology

[0002] After assembly, servers need to house server and hard drive components. This requires bracket rails to connect to the uprights on the same side, thus supporting the corresponding server, hard drive, and other cabinet-type components. Existing bracket rails are generally of fixed length. When placing electronic components, different bracket rails need to be configured according to the server's depth, resulting in the need for several bracket rails of varying lengths during assembly, which can easily lead to assembly errors. Furthermore, in actual assembly, existing bracket rails are only inserted into the corresponding mounting holes on the uprights via elastic protrusions at both ends, making them prone to derailment and component drop. Therefore, there is an urgent need to develop a versatile bracket rail with stable and reliable locking. Utility Model Content
