Description

Tool-free mounting bracket for front end of sliding rail of server cabinet

Technical Field

The invention relates to the technical field of slide rail installation, in particular to the technical field of slide rail installation of a server cabinet, and particularly relates to a tool-free front-end installation support of a slide rail of a server cabinet.

Background

With the continuous development of internet of things big data and cloud storage technology, a server cabinet for bearing a server tends to be large-sized, so that the length of a sliding rail for the server cabinet is increased continuously, and the installation difficulty of the sliding rail is increased. When the traditional sliding rail for the large-scale server cabinet is installed, two front and back installation personnel are needed to connect and lock the front end and the back end of the sliding rail with the cabinet through fastening screws and nuts respectively in front of and behind the cabinet, and the installation efficiency is low. The tool-free mounting of the server sliding rail bracket also occurs in the prior art, for example, the invention patent application with the publication number of CN103945671A discloses a tool-free mounting front bracket, wherein a locking elastic sheet is arranged at the position of the front bracket, which is connected with the end part, through a screw and a spring, the front end of the locking elastic sheet is bent to form a lock catch plate, the lock catch plate is enabled to protrude out of the end part of the front bracket, the tool-free mounting of the front bracket is realized by taking the screw as a fulcrum and the locking elastic sheet as a lever, and the lock catch plate of the locking elastic sheet is matched with a rack to realize lock catch; however, the front bracket has a problem of large occupied space, and when the front bracket is applied to a thin server slide rail, the locking spring sheet interferes with the middle rail of the slide rail to influence the extraction of the middle rail, so that the slide rail cannot be normally used. The invention patent with the publication number of CN204906937U discloses a tool-free mounting mechanism for a thin slide rail, wherein a latch plate at the front side of a locking elastic sheet is arranged into a pair of latch hooks respectively positioned at two sides of a front bracket so as to reserve a space for drawing and moving a middle rail of the slide rail for the front side surface of the front bracket, but the locking elastic sheet is elastically connected with the front bracket only through a rear end part, a screw and a spring, so that the connection rigidity of the whole locking elastic sheet and the front bracket is weaker, and the problem that the locking elastic sheet and a server cabinet are not reliably locked is caused, particularly, when the locking elastic sheet is very easy to shake seriously under the action of external force impact, even the phenomenon that the latch hooks are sharp, so that the stable safety of the server cabinet is influenced; in addition, the rear end of the locking elastic sheet is integrally arranged above the front bracket, so that the thickness of the whole front bracket is thicker, and the installation requirement of the ultrathin slide rail cannot be met.
