Mounting appratus for slide rail

Abstract

A mounting apparatus to be selectively connected to a first, a second and a third rack columns. The mounting apparatus includes a mounting bracket, two threaded pin secured to the mounting bracket, and two positioning pins respectively capped on the threaded pins. Each of the positioning pins includes a first segment with a greater diameter, and a second segment with a smaller diameter, and extending from an end of the first segment. The first and the second segments of the positioning pins are correspondingly configured to be located in the positioning pins of the first and the second rack columns. The threaded pins are configured to be located in the positioning pins of the third rack column.

1 . A mounting apparatus to be selectively connected to a first rack column, a second rack column, or a third rack column, respectively defining a positioning hole with a different size, the mounting apparatus comprising:
 a mounting bracket;   a threaded pin extending from the mounting bracket; and   a positioning pin detachably to be screwed to the threaded pin, the positioning pin comprising a first segment abutting against the mounting bracket, and a second segment extending from a distal end of the first segment opposite to the mounting bracket, a diameter of the first segment being greater than a diameter of the second segment;   wherein the first segment of the positioning pin is configured to extend into the positioning hole of the first rack column, the second segment of the positioning pin is configured to extend into the positioning hole of the second rack column, the threaded pin is configured to extend into the positioning hole of the third rack column.   
     
     
         2 . The mounting apparatus of  claim 1 , wherein the mounting bracket comprising a side plate and an end plate substantially perpendicularly extending from an end of the side plate, the threaded pin is secured to the end plate of the mounting bracket, and extends away from the side plate. 
     
     
         3 . The mounting apparatus of  claim 1 , wherein a screw hole is defined in the positioning pin, and extends though an end of the first segment of the positioning pin opposite to the second segment.
