Mechanical structure combining characteristics of 19-inch A-type case and 19-inch C-type case

Abstract

The invention discloses a mechanical structure combining the characteristics of a 19-inch A-type case and a 19-inch C-type case, and relates to the mechanical field of electronic equipment. The mechanical structure comprises an equipment case, an equipment mounting bracket, a left side sliding rail inner rail, a left side sliding rail outer rail, a right side sliding rail inner rail, a right side sliding rail outer rail, a handle, screws and the like. A typical 19-inch cabinet A-type case installation mode is adopted, the use characteristic that the C-type case can stretch out and draw back is achieved, electronic equipment can be conveniently pulled out through telescopic sliding rails to be operated or maintained, and structural parts for fixing the telescopic sliding rails do not need to be installed on the two sides of the cabinet any more; particularly, a feasible solution is provided under the condition that the equipment case needs to be telescopic, but a C-shaped case installation mode cannot be adopted.

Description

technical field [0001] The invention relates to a mechanical structure of electronic equipment, which adopts a typical 19-inch A-type cabinet loading method, which meets the installation characteristics and installation size requirements of the 19-inch A-type cabinet; The retractable function of the C-shaped chassis. Background technique [0002] GB / T 19520 "Electronic Equipment Mechanical Structure 482.6mm (19in) Series Mechanical Structural Dimensions" specifies three types of enclosures that can be installed in a typical 19-inch cabinet, namely: A-type models, B-type enclosures and C-type enclosures; A Only the installation flange of the chassis is fixed on the vertical member of the 19-inch cabinet with screws, which is easy to install; the C-type chassis is used to install the equipment that can be extended on the telescopic slide rail, and it is more convenient to use and maintain. [0003] Some electronic equipment on the shelves sometimes needs to be pulled out of t...

AI Technical Summary

Problems solved by technology

[0003] Some electronic equipment on the shelves sometimes needs to be pulled out of the cabinet to check the status or perform maintenance, and must be installed in a C-type cabinet; because there is no unified standard for telescopic slide rails, the structural parts for installing fixed slide rails on both sides of the cabinet need to be customized ; There are various specifications for the depth of the cabinet. In order to adapt to the cabinets of different depths, the structural parts of the fixed telescopic slide rails also need to be customized in various specifications, which brings inconvenience to production and installation; For electronic equipment, it is difficult or impossible to install the structural parts that fix the telescopic slide rails because the side door of the cabinet cannot be opened; Requirements
