The invention relates to the technical field of rudder blade observation hole covers, and discloses a rudder blade observation hole cover connecting structure which comprises a rudder blade body, an observation hole body is formed in the outer surface of the rudder blade body, an observation hole cover plate is arranged in the observation hole body, and a connecting plate is fixedly connected to the inner side of the rudder blade body. A first eye ring is fixedly connected to the outer surface, facing the inner side of the rudder blade body, of the observation hole cover plate, a second eye ring is fixedly connected to the outer surface of the top of the connecting plate, shackles are arranged on the outer surface of the first eye ring and the outer surface of the second eye ring, and a stainless steel chain is fixedly connected between the two shackles. The first eye ring and the second eye ring are arranged to be matched with the stainless steel chain and the shackle to fasten the observation hole cover plate, the problem that the observation hole cover plate is lost when opened for overhaul is avoided, and meanwhile compared with an internal hinge type connecting structure in the prior art, the observation hole cover plate has the advantages of being simple in type, convenient to operate and high in practicability. And the situation that the observation hole cover plate is inconvenient to open due to the fact that the hinge is corroded and stuck is avoided.
本发明涉及舵叶观察孔盖技术领域,且公开了一种舵叶观察孔盖的连接结构,包括舵叶本体,所述舵叶本体的外表面开设有观察孔本体,所述观察孔本体的内部设置有观察孔盖板,所述舵叶本体的内侧固定连接有连接板,所述观察孔盖板的朝向舵叶本体内侧的外表面固定连接有第一眼环,所述连接板的顶部外表面固定连接有第二眼环,所述第一眼环和第二眼环的外表面均设置有卸扣,两个所述卸扣之间固定连接有不锈钢链条。通过设置第一眼环和第二眼环配合不锈钢链条和卸扣对观察孔盖板拴住,避免了其打开检修时丢失的问题,同时相较于现有技术中内部铰链式连接结构,具有型式简单,操作方便,不会出现铰链腐蚀造成卡死而不便于打开观察孔盖板的特点。
