A supporting and positioning structure of server chassis including a metal plate combined with the chassis. A supporting body is combined at a lateral side of the mounting plate facing the server rack and includes a base and a pair of supporting plates. The base is fixed on the mounting plate, and the pair of supporting plates are arranged in parallel and at an interval so that a slot is formed therebetween. Moreover, a roller is rotatably disposed in the slot so that the chassis of the server rack can be supported and held.

A synchronic drawer slide rail system with a mute springback function includes: two slide rail units, wherein two external faces of a drawer are connected to two internal faces of a cabinet in a relative sliding form through the slide rail units which are symmetrically arranged; the two slide rail units are synchronically connected to each other through a synchronizing mechanism; wherein a shell unit is fixed on each of the two internal faces of the cabinet; a linear groove extending along a relative sliding direction of the drawer and the cabinet is provided on a side face, which faces the drawer, of the shell unit; each of the slide rail units is installed in the linear groove; a horizontal board extending towards the drawer is arranged at a bottom face of the shell unit, and a rack is provided on an inner end of the horizontal board.

This showcase (10) for conserving and displaying objects in a protective environment comprises a frame (20), at least one drawer (30), a pair of sliding guides (40) for each drawer (30), and a motorised actuation system (50) formed by a first arm (51) and an actuator (52). The showcase (10) with this motorised actuation system (50) makes it possible to minimise the vibrations and the sudden movements of the drawers (30) when opening and closing, hence it limits accelerations at any point of the travel, thus allowing the correct conservation of the objects displayed in the drawers (30).

One embodiment of the present invention relates to a push-to-open device mounted on a slide device having a fixed rail and a movable rail slidably provided on the fixed rail, and provides a push-to-open device comprising: a main body mounted on the fixed rail, and having a guide path and an inner space; a slider, which is provided on the main body so as to be capable of being caught by or released from a catching member of the movable rail, and moves along the guide path; a shaft, which has one end connected to the slider and the other end connected to an elastic member provided at the main body, and has a plurality of operating protrusions protruding from the outer peripheral surface thereof and a plurality of catching protrusions protruding at positions spaced a predetermined distance from the operating protrusions in the longitudinal direction; a rotator, which is provided at the main body, and engages with the operating protrusion to rotate in one direction by means of the movement of the shaft during a push operation, and thus is repeatedly circulated so as to be locked to or released from the catching protrusions; and the elastic member provided at the main body and elastically supporting the locking or releasing operation of the shaft and the rotator.
