Description

Interim auxiliary hole airtight test plugging structure peculiar to vessel

Technical field

The utility model relates to a kind of interim auxiliary hole airtight test plugging structure peculiar to vessel.

Background technology

Boats and ships are satisfied production needs in manufacture process; For example personnel are current, tape draws and establish, paints ventilation etc.; Usually offer provisional auxiliary hole, and this auxiliary hole carries out shutoff often after the complete type in cabin, place, this hole finishes, therefore need carry out temporary blocking during tightness test this auxiliary hole in the cabin on tank top plate, outside plate, deck etc. and other structure; Common way is to use the method for steel plate welding with interim blocking technological holes; Excision again after airtight test finishes, this way is all long in shutoff, time required when removing, and welding, gas cutting and polishing work are arranged.

Summary of the invention

The purpose of the utility model provides a kind of interim auxiliary hole airtight test plugging structure peculiar to vessel easily and efficiently.

The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of interim auxiliary hole airtight test plugging structure peculiar to vessel; Comprise shutoff blind plate (1), fastening backboard (2), rubber cradle (3), double end stud (4) and handle (6); Tapping is connected between said shutoff blind plate (1) and the double end stud (4); Said handle (6) is fixed on the shutoff blind plate (1), is fixed on the hull (7) through double end stud (4) and nut (5) between said shutoff blind plate (1), fastening backboard (2) and the rubber cradle (3).

Have through hole on the said fastening backboard (2).

The utility model interim auxiliary hole airtight test plugging structure peculiar to vessel, have simple to operate, economical with materials, the beneficial effect of cost-cutting.
