Description

Technical Field

[0001] The utility model belongs to the technical field of communication equipment, and particularly relates to a lightweight adjustable double-sided guide rail for a communication chassis. Background Art

[0002] A guide rail, also known as a slide rail, is mainly a groove or ridge made of metal or other materials, which can bear, fix, guide a moving device or equipment and reduce its friction. It is used in occasions of linear reciprocating motion, has a higher rated load than a linear bearing, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. It is widely used in various communication chassis, and various boards often use the notches on the guide rail as a guide to plug and unplug and dock with the connectors on the backplane.

[0003] Nowadays, the guide rails applied to the chassis on the market are various, mostly using metal machining, metal die casting, plastic injection molding, stamping, etc. Due to being restricted by the internal space size of the chassis, the overall contour requirements of the guide rail are controlled more compactly, and a certain load-bearing capacity is required. The metal machining method takes a long time and has high costs. Die casting, injection molding, and stamping require upfront investment in molds. Once the mold is formed, the structure of the guide rail cannot be easily changed. If it is indeed necessary to change, a certain mold repair cost needs to be invested. With the continuous development of the times, the boards applied in the communication chassis also need to be continuously upgraded and updated, etc., and the guide rail needs to adapt to various boards, so it brings various troubles to the manufacture of the chassis guide rail.

[0004] Based on this, there is an urgent need for a lightweight adjustable double-sided guide rail for a communication chassis, so that it can meet the application requirements of various chassis boards. Summary of the Utility Model
