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.

    本发明公开了一种舱壁式隐藏连接节点,包括背贴板,所述背贴板开设有通孔二,所述通孔二中焊接有内螺纹圆钢筒,所述内螺纹圆钢筒开设有螺纹孔一和圆锥槽,所述舱壁开设连接节点处开设有通孔一,所述背贴板通过焊接固定连接在舱壁内侧,所述内螺纹圆钢筒头部安装在通孔一中;在不连接设备时,所述螺纹孔一中固定安装有十字沉头螺栓;在搭设构筑物或挂载其他设备时,所述螺纹孔一通过外六角螺栓一和外六角螺栓二固定安装有连接副二;采用上述的结构后,能够使舱壁平整无凸起物,外观美观;有效的减少了雷达反射面积,使舰船具有更好的隐身性能;更为舰船上搭设外部构筑物时提供固定连接节点,操作简单,安全可靠。
