The present invention relates to a mask, and more particularly to a rotatable folding diving mask.
With the demand for various sports, diving has become one of the emerging sports loved by more and more people. When diving, people would like to see the scenery underwater. Therefore, it is possible to wear a diving mask for breathing and watching underwater scenery.
A conventional diving mask includes a mask and a snorkel. In order to make the diving mask easy to carry and reduce the occupied space, the snorkel and the mask are usually connected by a plug-in structure. This plug-in connection structure leads to poor waterproof performance, and the snorkel is easy to fall and lose to affect the carrying. The diving mask also includes an elastic strap. In the prior art, the elastic strap is generally fastened to the mask, which makes the disassembly and replacement inconvenient.
In order to enable people to breathe smoothly under water, an air passage for breathing is arranged between the mask and the snorkel. The air passage in the prior art is usually arranged by using a tube structure. A single sealed tube is used to form the air passage, which occupies larger space and needs more production materials. In some masks, the air passage is surrounded by a plurality of structures. However, the connection structure is complicated, and the sealing of the air passage is poor. After a period of time, the air passage for breathing may be unsatisfactory and affect the use.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
In view of the drawbacks of the prior art, the primary object of the present invention is to provide a rotatable folding diving mask, which is easy to operate and fold, reduces the occupied space, and is easy to disassemble and replace an elastic binding strap. Besides, its structural design is ingenious, the layout is clever, and it has better sealing effect.
In order to achieve the above object, the present invention adopts the following technical solutions.
A rotatable folding diving mask comprises a mask, a snorkel, and an elastic binding strap. The snorkel is rotatably connected to an upper end of a front side of the mask in a foldable manner. The elastic binding strap is detachably connected to a rear side of the mask.
The mask is provided with a first connecting portion for connecting the snorkel. The snorkel is provided with a second connecting portion for connecting the mask. The first connecting portion and the second connecting portion are connected through a rotating shaft.
One side of the first connecting portion is provided with a control button for controlling the snorkel to be rotated and folded. One side of the second connecting portion is provided with a positioning recess. One end of the control button has a positioning buckle. When the snorkel is in an unfolded state, the positioning buckle is positioned in the positioning recess. 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 is provided with a connecting buckle for connecting the mask. The mask is provided with a locating buckle for connecting the elastic binding strap. The connecting buckle is mated with the locating buckle.
Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions that by connecting the snorkel and the mask through the rotating shaft and combining with the structural design of the control button, the rotating and folding structure is provided, and the operation is simple and easy to fold, thereby achieving the purpose of reducing the occupied space. The elastic binding strap is connected to the mask through the buckle connection structure, so that the elastic binding strap can be easily disassembled and replaced, and the structure is simple and ingenious.
