Diving mask

Abstract

A diving mask includes a metal frame, a soft rubber mask, and a lens. The diving mask consists of the metal frame, the soft rubber mask and the lens. The frame of the diving mask is a metal frame. The metal frame includes an outer frame and an inner frame. The lens is sandwiched between the inner frame and the outer frame and is fixed through a fixing structure, which improves the structural stability of the diving mask.

What is claimed is: 
     
         1 . A diving mask, comprising a metal frame, a soft rubber mask, and a lens; the metal frame including an outer frame and an inner frame, an inner edge of an outer side of the outer frame being provided with an accommodating groove for accommodating the lens and the inner frame, the lens and the inner frame being sequentially held in the accommodating groove, the inner frame blocking an outer side of the lens, a fixing structure for fixing the inner frame and the outer frame to each other being disposed between the inner frame and the outer frame; the soft rubber mask being fixedly connected to an edge of an inner side of the outer frame. 
     
     
         2 . The diving mask as claimed in  claim 1 , wherein the fixing structure includes a plurality of spaced engaging slots disposed in the accommodating groove of the outer frame and a plurality of spaced engaging blocks disposed on an outer edge of the inner frame, and the engaging blocks are detachably mated to the engaging slots, respectively. 
     
     
         3 . The diving mask as claimed in  claim 1 , wherein two positioning blocks are provided on a nasal bridge region of the inner frame, the lens is provided with two positioning slots corresponding to the two positioning blocks, and the two positioning blocks are detachably mated to the two positioning slots. 
     
     
         4 . The diving mask as claimed in  claim 1 , wherein a positioning protrusion is longitudinally disposed on an upper end of a nasal bridge region of the outer frame, an upper end of a nasal bridge region of the inner frame is formed with a positioning groove corresponding to the positioning protrusion, and the positioning protrusion is detachably mated to the positioning groove. 
     
     
         5 . The diving mask as claimed in  claim 4 , wherein the positioning protrusion has a raised piece extending forwardly, the positioning groove is formed with a through hole corresponding to the raised piece, and the raised piece is detachably inserted into the through hole. 
     
     
         6 . The diving mask as claimed in  claim 5 , wherein an engaging hook is vertically disposed in the through hole, an engaging hole is disposed on the raised piece, and the engaging hook is detachably inserted into the engaging hole. 
     
     
         7 . The diving mask as claimed in  claim 1 , wherein a lower edge of the outer frame is provided with a limiting block protruding forwardly, a lower edge of the inner frame is formed with a limiting hole corresponding to the limiting block, and the limiting block is detachably inserted into the limiting hole.
