Abstract: A pair of ultrathin slide rails capable of rapid installation and removal are disclosed. The slide rails are specially configured to provide an ultrathin three-section slide rail mechanism. Switchable auxiliary pins are inserted into threaded holes formed in bent sections at both ends of each slide rail, allowing the slide rails to be rapidly positioned in positioning holes of slide rail posts of a chassis and secured in place by fastening screws. The fastening screws are replaceable by resilient fasteners provided on the bent sections at both ends of each slide rail so that the slide rails can be rapidly installed and removed by virtue of the resilient fasteners and the auxiliary pins.

Abstract: A tool-free rapid assembly/disassembly slide rail device is characterized in that each of a front slide rail and a rear slide rail has an end inserted by rectangular or circular flange positioning blocks of a positioning element and is detachably assembled with a resilient retaining element, wherein the positioning element is retained by the resilient retaining element to allow rapid assembly and disassembly of the slide rail device.
