Abstract
A structural improvement of a diving mask which consists of a main frame, a sub-frame, a lens and a skirt. Tenons are provided on the sub-frame, engaging mortises on the lens. A soft connecting edge is provided on the skirt, which is closely connected with a periphery of the lens. A rigid structure is established by the tenon jointing the sub-frame with the lens, and the connecting frame of the skirt is closely connected with periphery of the lens, when the main frame is connected with sub-frame. This construction allows the diving mask lens removal and keeps a stable connecting state after its assembly.
