An optical distribution frame cabinet, comprising a cabinet, wherein a plurality of optical distribution frames are disposed inside the cabinet; wherein for each of the plurality of optical distribution frames: a first end of the optical distribution frame is configured to be hinged to the cabinet so that the optical distribution frame can rotate into or out of the cabinet, and a sliding groove is disposed on an end face of a second end of the optical distribution frame; the sliding groove extends in a longitudinal direction of the optical distribution frame; a mounting ear component is disposed on an end face of the cabinet and fastened to the cabinet, and the mounting ear component is convexly disposed facing the optical distribution frame when the optical distribution frame is rotated out of the cabinet; and when the optical distribution frame rotates into the cabinet, the mounting ear component is inserted into the sliding groove and slides in a guide direction of the sliding groove, until the optical distribution frame is inserted into the cabinet, characterized in that a size of an opening of the sliding groove gradually increases in a direction away from a cabinet door of the cabinet a cutting plane of the sliding groove is broadening in a longitudinal direction of the optical distribution frame, and a first notch and a second notch are oppositely disposed at two ends of the broadening sliding groove; the first notch is disposed near the cabinet door of the cabinet, the second notch is disposed away from the cabinet door of the cabinet, and a cross-sectional area of the second notch is greater than that of the first notch; and when the mounting ear component is inserted into the second notch, a gap is formed between the mounting ear component and the second notch. a first end of the optical distribution frame is configured to be hinged to the cabinet so that the optical distribution frame can rotate into or out of the cabinet, and a sliding groove is disposed on an end face of a second end of the optical distribution frame; the sliding groove extends in a longitudinal direction of the optical distribution frame; a mounting ear component is disposed on an end face of the cabinet and fastened to the cabinet, and the mounting ear component is convexly disposed facing the optical distribution frame when the optical distribution frame is rotated out of the cabinet; and when the optical distribution frame rotates into the cabinet, the mounting ear component is inserted into the sliding groove and slides in a guide direction of the sliding groove, until the optical distribution frame is inserted into the cabinet, characterized in that a size of an opening of the sliding groove gradually increases in a direction away from a cabinet door of the cabinet a cutting plane of the sliding groove is broadening in a longitudinal direction of the optical distribution frame, and a first notch and a second notch are oppositely disposed at two ends of the broadening sliding groove; the first notch is disposed near the cabinet door of the cabinet, the second notch is disposed away from the cabinet door of the cabinet, and a cross-sectional area of the second notch is greater than that of the first notch; and when the mounting ear component is inserted into the second notch, a gap is formed between the mounting ear component and the second notch.
