Bulkhead type hidden connecting joint

Abstract

The invention discloses a bulkhead type hidden connecting joint. The connecting joint comprises a back flitch plate, a second through hole is formed in the back flitch plate, an internal thread roundsteel cylinder is welded in the second through hole, a first threaded hole and a conical groove are formed in the internal thread round steel cylinder, and a first through hole is formed at the position, at the connecting joint, of a bulkhead. The back flitch plate is fixedly connected to the inner side of the bulkhead through welding, and the head of the internal thread round steel cylinder is installed in the first through hole; when equipment is not connected, a cross countersunk bolt is fixedly mounted in a first threaded hole; when a structure is erected or other equipment is hung, the first threaded hole is fixedly provided with a second connecting pair through a first outer hexagon bolt and a second outer hexagon bolt; after the structure is adopted, the bulkhead can be flat and free of protrusions, and the appearance is attractive; the radar reflection area is effectively reduced, so that a ship has better stealth performance; and the fixed connecting joint is provided when anexternal structure is erected on the ship, operation is easy, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of equipment installation and connection, in particular to a bulkhead-type hidden connection node. Background technique [0002] The wonders of the sea are nothing more than naval battles, and warships are the main players in naval battles. Over the centuries, warships have experienced a development process from small to large, from wood to armor, and from primitive equipment to modern equipment. [0003] Warships started with wooden structures and sailed by sculls. In the 15th century, sailing ships appeared. In 1814, the United States successfully developed a sailless warship powered by steam. Screw propulsion, in 1834, wooden warships began to transform into ironclad ships. In modern times, due to the development of the oil processing industry and the promotion of war practice, the development of naval ships has skyrocketed from the end of the 19th century to the First and Second World Wars. In the past ...

AI Technical Summary

Problems solved by technology

[0004] When it is necessary to set up structures or mount other equipment on the ship, the traditional method generally uses welding lugs or connectors on the bulkhead, resulting in too many protrusions on the bulkhead and increasing the radar wave reflection area, which is harmful to the ship. It will adversely affect the stealth performance of the ship, and affect the appearance of the ship
