Abstract
The invention discloses a wire sealing device, and belongs to the technical field of airplane structure strength tests. The wire sealing device comprises a test wire, sealing glue, a sealing cloth strip, a wedge-shaped piece, a boss pipe, a sealing ring, a test piece, a flat gasket, a spring gasket, a nut and a fastener. After the test wire is coated with the sealing glue, the sealing strip is wound around the test wire to form the wedge-shaped piece, the two ends of the wedge-shaped piece are different in diameter and include the large-diameter end and the small-diameter end, the small-diameter end of the wedge-shaped piece sequentially passes through the boss pipe, and a threaded pipe of the boss pipe sequentially passes through the sealing ring and the test piece and is fixed to the test piece through the flat gasket, the spring gasket and the nut. The small-diameter end of the wedge-shaped piece and the boss pipe are pressed and sealed through the fastener, and the large-diameter end of the wedge-shaped piece and the boss pipe are matched, fixed and pressed. The wire sealing device is tight in sealing, free of air leakage, simple in structure, reliable in performance, low in manufacturing cost and convenient to install. The test piece is clean and tidy due to the fact that the outer portion of the test piece does not need to be coated with the sealing glue.
