The invention relates to the technical field, and discloses a marine aviation explosion-proof indicating lamp which comprises a box body, a glass cover is arranged at the upper end of the box body, a light-emitting plate is arranged in the box body, the box body comprises an upper mounting plate, a connecting plate and a lower mounting plate which are sequentially connected from top to bottom, and a convex edge extending inwards is arranged at the upper end of the upper mounting plate. A protruding edge is arranged on the upper end face of the connecting plate, a strip-shaped sealing gasket is arranged below the protruding edge, a sealing groove is formed in the end face of the connecting plate, an O-shaped sealing ring is arranged in the sealing groove, the glass cover is clamped between the strip-shaped sealing gasket and the O-shaped sealing ring, and an upper gap is reserved between the upper end face of the glass cover and the lower end face of the protruding edge. A lower gap is reserved between the lower end face of the glass cover and the upper end face of the connecting plate, and the lower mounting plate is provided with a light-emitting plate and a self-cleaning mechanism. The glass cover floats between the O-shaped sealing ring and the strip-shaped sealing gasket, so that the end face of the glass cover is in flexible contact with the sealing ring, rigid contact between the glass cover and the box body is avoided, and the anti-explosion performance of the glass cover is improved.
本发明涉及技术领域,公开了一种船用航空的防爆指示灯,包括盒体,所述盒体的上端设有玻璃罩,盒体中设有发光板,所述盒体包括从上到下依次连接的上安装板、连接板和下安装板,所述上安装板的上端设有向内延伸的凸边,凸边的下方设有条形密封垫,所述连接板的端面设有密封槽,密封槽中设有O型密封圈,所述条形密封垫与O型密封圈之间夹合有所述玻璃罩,所述玻璃罩的上端面与凸边的下端面之间留有上间隙,玻璃罩的下端面与连接板的上端面之间均留有下间隙,所述下安装板安装有发光板以及自清洁机构。本发明玻璃罩浮动在O型密封圈与条形密封垫之间,让玻璃罩的端面与密封圈柔性接触,避免玻璃罩与盒体刚性接触,提高玻璃罩的防爆裂性能。
