The invention relates to the field of power distribution boxes, in particular to an instrument door mechanism of a push-pull type distribution box and the power distribution box. The instrument door mechanism of the push-pull type distribution box comprises an instrument door body, indicator lamps, a positioning block, an adjusting piece, a protruding part, a basic block, an inserting rod, a limiting rod, a bearing block, a first spring, a connecting part, a connecting piece, a sliding block and a rotating rod, and the indicator lamps are embedded in the instrument door body at equal intervals; and positioning blocks are fixedly connected to the top and one side of the inner wall of the instrument door body. According to the instrument door mechanism of the push-pull type distribution box and the power distribution box provided by the invention, the instrument door device is arranged on the power distribution box, so that the opening and closing of the instrument door are facilitated, the instrument door can be adjusted to turn upwards or laterally according to different requirements, and the problem that the instrument door is difficult to turn over due to the shielding of foreign objects is avoided; and through the wire arrangement mechanism, lines in the distribution box are connected more regularly, so that the distribution box is easier and more convenient to maintain.
