Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention and not to limit its scope.
Currently, 19 inch standard cabinets have the following problems when using three-section rails:
the width of three section guide rail itself is narrower, and the model width that commonly uses is 12.7mm, and the width is great does not also exceed 20mm, and 19 inches standard rack inside width is great (516mm), and machine case width is then less (generally 415 ~ 420mm), if directly install three section guide rail in the rack side, the rail still has certain distance apart from machine case side in the guide rail (taking the quick-witted case of 415mm width as an example, the distance is 37.8mm), can't be connected with quick-witted case.
Therefore, a 19-inch standard cabinet needs a guide rail adapter to connect the three-section guide rail and the cabinet, the traditional guide rail adapter is generally a solid metal plate, one end of the traditional guide rail adapter is installed on the installation surface on the side surface of the cabinet, the other end of the traditional guide rail adapter is connected with the outer rail of the guide rail, the thickness of the adapter needs to be matched with the width of a specific cabinet, once the adapter is installed, the position of the adapter is basically fixed, and the adapter is difficult to adjust, so that the application of the three-section guide rail on the 19-.
Through a great deal of research, the applicant designs the guide rail switching device for connecting the three-section guide rail and the side surface of the cabinet aiming at the problems that the traditional guide rail switching device is difficult to adjust, not flexible and convenient enough and the like, and the installation height and the width of the guide rail in the cabinet can be adjusted after the guide rail switching device is installed, so that the three-section guide rail switching device can be suitable for cabinets with different widths.
