Patent attributes
A casing includes a shell, at least one carrier tray, at least one slide rail assembly and a buffering component. The shell has an accommodating space and an opening corresponding to the accommodating space. The carrier tray is located in the accommodating space. The slide rail assembly includes an outer rail fixed to the shell, a middle rail, and an inner rail. The carrier tray is fixed to the inner rail, such that the carrier tray is slidably assembled with the shell through the slide rail assembly, thereby being extracted outward from the opening or entering the accommodating space through the opening. The buffering component is assembled with the shell, penetrates through the shell and the outer rail, and is pressed against the middle rail. When the middle rail slides relative to the outer rail, the slide rail assembly is buffered by the buffering component.
