Adjustable mining air window structure with lock

The invention relates to the technical field of underground mines, in particular to an adjustable mining air window structure with a lock, which comprises an outer frame body mounted at a ventilation opening of a fan chamber, and is characterized in that an upper track and a lower track which are parallel to each other are respectively bolted and fixed on rock masses at the upper part and the lower part of the outer side of the outer frame body; an air window rigid baffle is arranged between the upper rail and the lower rail in a sliding and clamping mode, an opening and closing adjusting mechanism is arranged on the rock mass on the left side of the air window rigid baffle, and the opening and closing adjusting mechanism is used for driving the air window rigid baffle to achieve reciprocating translation in the length direction of the upper rail and the lower rail; in the translation process of the air window rigid baffle, control over the opening degree of the ventilation opening of the fan chamber can be a
