Rotatable folding diving mask

Abstract

A rotatable folding diving mask includes a mask, a snorkel, and an elastic binding strap. By connecting the snorkel and the mask through a rotating shaft and combining with the structural design of a control button, a rotating and folding structure is provided, and the operation is simple and it is easy to fold, thereby achieving the purpose of reducing the occupied space. The elastic binding strap is connected to the mask through a buckle connection structure, so that the elastic binding strap can be easily disassembled and replaced, and the structure is simple and ingenious.

What is claimed is: 
     
         1 . A rotatable folding diving mask, comprising a mask, a snorkel, and an elastic binding strap; the snorkel being rotatably connected to an upper end of a front side of the mask in a foldable manner, the elastic binding strap being detachably connected to a rear side of the mask;
 the mask being provided with a first connecting portion for connecting the snorkel, the snorkel being provided with a second connecting portion for connecting the mask, the first connecting portion and the second connecting portion being connected through a rotating shaft;   one side of the first connecting portion being provided with a control button for controlling the snorkel to be rotated and folded, one side of the second connecting portion being provided with a positioning recess, one end of the control button having a positioning buckle; wherein when the snorkel is in an unfolded state, the positioning buckle is positioned in the positioning recess; wherein when the snorkel is to be folded, the control button is pressed and then the positioning buckle is disengaged from the positioning recess, and the snorkel can be rotated and folded into a cavity at the rear side of the mask through the rotating shaft;   the elastic binding strap being provided with a connecting buckle for connecting the mask, the mask being provided with a locating buckle for connecting the elastic binding strap, the connecting buckle being mated with the locating buckle.   
     
     
         2 . The rotatable folding diving mask as claimed in  claim 1 , wherein the control button includes a press portion and a linkage portion; the linkage portion is rotatably connected to the mask through a positioning shaft; one side of the press portion is convexly provided with a stroke protrusion, the linkage portion is formed with a stroke groove, the stroke protrusion is movably fitted in the stroke groove; the positioning buckle is disposed on the linkage portion; when the press portion is pressed toward the snorkel, the press portion moves toward the snorkel and links the stroke projection to displace in the stroke groove, the linkage portion is rotated by the press portion, and the positioning buckle is disengaged from the positioning recess by rotation of the linkage portion. 
     
     
         3 . The rotatable folding diving mask as claimed in  claim 2 , wherein the press portion is provided with a limiting protrusion, the limiting protrusion is located at one side of the stroke protrusion; the linkage portion is provided with a first limiting slot and a second limiting slot, the first limiting slot and the second limiting slot are spaced apart from each other, the first limiting slot is disposed farther away from the positioning buckle than the second limiting slot; the linkage portion is provided with a stopping portion; when the snorkel is in the unfolded state, the limiting protrusion is confined in the first limiting slot, and the press portion is limited to an outer surface of the mask and cannot act on the linkage portion; when the snorkel is to be folded, the press portion is pressed, and the limiting protrusion is displaced toward the snorkel with the press portion until the limiting protrusion is confined in the second limiting slot, one end of the stroke protrusion is limited to one side of the stopping portion, the press portion stops displacement, the press portion is disengaged from restriction of the mask, the linkage portion is rotated by the press portion, and the positioning buckle is disengaged from the positioning recess by the rotation of the linkage portion. 
     
     
         4 . The rotatable folding diving mask as claimed in  claim 2 , wherein the linkage portion further has an elastic rotation support portion for supporting the rotation of the linkage portion, the elastic rotation support portion and the positioning buckle are disposed at two ends of the linkage portion respectively, and the stroke groove is located between the elastic rotation support portion and the positioning buckle. 
     
     
         5 . The rotatable folding diving mask as claimed in  claim 4 , wherein the elastic rotation support portion is an arc-shaped elastic portion, and the arc-shaped elastic portion is curved outward from one side of the linkage portion. 
     
     
         6 . The rotatable folding diving mask as claimed in  claim 1 , wherein the locating buckle is detachably connected to the mask; the locating buckle has an elastic engaging block, the elastic engaging block has an engaging block body and an elastic buckle arm connected to the engaging block body; the mask is formed with an engaging hole, one side of the engaging hole communicates with a barb groove; the elastic engaging block is detachably fitted into the engaging hole, the engaging block body is fitted into the engaging hole, and the elastic buckle arm is engaged in the barb groove. 
     
     
         7 . The rotatable folding diving mask as claimed in  claim 1 , wherein the mask includes a mask frame, a mask pad and a mask lens, the mask pad and the mask lens are mounted on the mask frame;
 the mask frame has an air groove, the mask pad has a sealing wall, the mask lens has a first connecting wall and a second connecting wall, the second connecting wall extends outward from an outer side of the first connecting wall; the sealing wall is located between the mask frame and the first connecting wall;   an inner side of the sealing wall is in close contact with the outer side of the first connecting wall, one end of the sealing wall is connected to the second connecting wall, one end of the second connecting wall is connected to the mask frame, and an outer side of the sealing wall seals the air groove to form an air passage.   
     
     
         8 . The rotatable folding diving mask as claimed in  claim 1 , wherein the mask has a first mounting trough, the snorkel has a second mounting trough; one end of the control button is mounted in the first mounting trough, another end of the control button extends into the second mounting trough; and the positioning recess is formed in the second mounting trough. 
     
     
         9 . The rotatable folding diving mask as claimed in  claim 8 , wherein the first connecting portion has a first connecting hole, the second connecting portion has a second connecting hole, the first connecting hole and the second connecting hole are connected through the rotating shaft; the first mounting trough and the second mounting trough are located at opposite sides of the first connecting hole and the second connecting, respectively.
