| description | The utility model belongs to the field of electronic drawing auditing, and particularly relates to a drawing projection device for electronic drawing auditing, which comprises a first track, a first sliding seat capable of sliding back and forth is arranged in the first track, and the other end of the first sliding seat is connected with a cross frame; second rails are symmetrically installed at the two ends of the transverse frame. The projector is used for assisting in architectural drawing review, when a large-size drawing needs to be displayed, the two projectors are moved to the positions close to the two second rails, collection of projection intersection planes of the two projectors is achieved, and the large-size drawing can be displayed on the same projection plane; through cooperation of the rail sliding seat structures, after the two projectors move in the opposite directions, split-screen display and projection distance adjustment of a to-be-checked picture can be carried out; in cooperation with |
