1. A fiber optic distribution frame comprising:
a casing unit; and
a plurality of tray units stacked on one another along an up-down direction and disposed in said casing unit, each of said tray units including a partition plate, a plurality of inner guiding rails disposed on and above said partition plate and spaced apart from one another along a horizontal direction transverse to the up-down direction, and a plurality of mounting seats each disposed between adjacent two of said inner guiding rails and movable forwardly and rearwardly along a front-rear direction transverse to the up-down direction and the horizontal direction to be removed from the adjacent two of said inner guiding rails;
wherein each of said inner guiding rails of each of said tray units includes
two plate portions that are spaced apart from each other along the up-down direction,
a connecting portion that is connected between said plate portions, and that has two ends opposite along the front-rear direction and being resilient and flexible, and
two protruding portions that protrude from said coupling portion in the same direction along the horizontal direction, said plate portions cooperating with said connecting portion to define a main guiding groove and an auxiliary guiding groove that are located respectively at opposite sides of said connecting portion along the horizontal direction, said protruding portions extending from said connecting portion into said main guiding groove;
wherein each of said mounting seats includes a seat portion that has two lateral walls opposite along the horizontal direction, a slidable portion that protrudes from one of said lateral walls of said seat portion along the horizontal direction, and a guiding unit that protrudes from the other one of said lateral walls of said seat portion away from said slidable portion along the horizontal direction, said guiding unit including two positioning slots indented along the horizontal direction, spaced apart from each other along the front-rear direction, and respectively and detachably engaging said protruding portions of an adjacent one of said inner guiding rails; and
wherein, for each of said mounting seats, said slidable portion and said guiding unit slidably and respectively engage an adjacent one of said auxiliary guiding grooves of said inner guiding rails and an adjacent one of said main guiding grooves of said inner guiding rails.
