[0034] The self-inspection sealing mechanism 3 includes a pressing frame 301, a fixed frame 304 and a front transparent soft film 307. The pressing frame 301 is placed inside the orifice 5. A plurality of card slots 302 are equidistantly arranged on the front circumference of the pressing frame 301. The card slots 302 are all engaged with the buckles 303. The buckles 303 are all clamped at the inner edge of the fixed frame 304. The front side of the fixed frame 304 is fixedly connected to the soft glue folding cavity 305. The front side of the soft glue folding cavity 305 is fixedly connected to the pressure plate 306. The front transparent soft film 307 is installed on the inner rear side of the front mobile phone case 2.

[0035] By first pressing the pressing plate 306, the soft glue folding cavity 305 is stored inside the fixed frame 304, and the buckle 303 on the fixed frame 304 is fastened and fixed with the card slot 302 on the pressing frame 301. When the soft glue folding cavity 305 is folded and stored, the air inside is squeezed toward the front transparent soft film 307 inside the front mobile phone case 2 to make it bulge. The bulged front transparent soft film 307 keeps the air in the internal cavity from dissipating for a certain period of time. The cavity is in a sealed state, which is used for visually checking the effectiveness of the sealing and safe use. Therefore, the waterproof mobile phone protective case has a self-testing sealing device, which can be used for the mobile phone waterproof protective case to self-test the waterproof sealing of the mobile phone waterproof protective case when in use, effectively solving the problem of using the mobile phone waterproof protective case when it has waterproof sealing performance, and preventing the mobile phone from being damaged by water when the waterproof performance of the mobile phone waterproof protective case is weakened or fails, thereby better improving the effective use rate of the mobile phone waterproof case product.

The clamping ring 601 is engaged with the clamping groove 602, and the clamping groove 602 is set at the rear edge of the front mobile phone case 2. Through the setting of the clamping ring 601 and the clamping groove 602, the mobile phone waterproof case cavity 1 and the front mobile phone case 2 are clamped and fixed together to form a complete mobile phone case.

[0037] An air squeezing area 4 is formed between the soft-glue folding cavity 305 and the front transparent soft film 307 , and the soft-glue folding cavity 305 presses air toward the front transparent soft film 307 .

[0038] The pressing plate 306, the soft rubber folding cavity 305, and the fixed frame 304 are arranged in sequence front to back to form a structure for self-testing sealing of the mobile phone case.

[0039] The card slot 302 is rotatably connected to the buckle 303 , and the buckle 303 on the fixed frame 304 is rotated into the card slot 302 for locking and fixing.

[0040] The front transparent soft film 307 is squeezed and bulged by the soft glue folding cavity 305 to contact the mobile phone, and the air is squeezed toward the front transparent soft film 307 through the soft glue folding cavity 305, and then the front transparent soft film 307 bulges to seal the mobile phone in the mobile phone case.

[0041] A bottom groove 14 is provided in the middle of the bottom surface of the front mobile phone case 2, and a nail rod 15 is provided inside the bottom groove 14. The nail rod 15 is rotatably connected to one side of the movable arc buckle 11, and a square buckle 10 is installed on the other side of the movable arc buckle 11. The square buckle 10 is installed with an elastic column 13 on the side away from the square buckle 10, and the outer surface of the elastic column 13 is sleeved with a spring 12. A square groove 7 is provided in the middle of the bottom surface of the mobile phone waterproof shell cavity 1, and the square groove 7 is provided with a through groove 8 on the side away from the square groove 7, and a groove 9 is provided on the side close to the through groove 8. The square buckle 10 is engaged with the square groove 7, and the elastic column 13 and the spring 12 both penetrate the through groove 8 and extend into the groove 9. By turning the movable arc buckle 11 to the square groove 7, the square buckle 10 is pushed into the square groove 7, and then the elastic columns 13 and spring 12 on both sides of the square buckle 10 are extended into the through groove 8 and the groove 9 for clamping and fixing, so that the front mobile phone case 2 and the mobile phone waterproof shell cavity 1 are reinforced and fixed, and are easy to disassemble.

[0042] A method for using a self-testing sealing device for a waterproof mobile phone protective case, comprising the following steps:

[0043] Step 1: First, prepare the following accessories: the pressing frame 301, the card slot 302, the buckle 303, the fixed frame 304, the soft rubber folding cavity 305, the pressing plate 306, the front transparent soft film 307, the front mobile phone case 2 and the mobile phone waterproof case cavity 1;

[0044] Step 2: Rotate and install the pressing plate 306, the soft rubber folding cavity 305, the fixed frame 304 and the buckle 303 with the card slot 302 on the pressing frame 301 installed on the front mobile phone case 2, so that the soft rubber folding cavity 305 is fixed to the front side of the front mobile phone case 2;

[0045] Step 3: Insert the mobile phone into the cell phone waterproof case cavity 1, and engage the clamping ring 601 installed on the front side of the cell phone waterproof case cavity 1 with the clamping groove 602 on the rear side of the front cell phone case 2 to fix the mobile phone in place. The mobile phone will be fixed inside the cell phone waterproof case cavity 1 and the front cell phone case 2, and the mobile phone will be in contact with the front transparent soft film 307.

[0046] Step 4. Before using the mobile phone waterproof case, press the pressing plate 306 to store the soft rubber folding cavity 305 inside the fixed frame 304, and fasten the buckle 303 on the fixed frame 304 with the card slot 302 on the pressing frame 301 to each other. When the soft rubber folding cavity 305 is folded and stored, the air inside is squeezed toward the front transparent soft film 307 inside the front mobile phone case 2 to make it bulge. The bulging front transparent soft film 307 keeps the air in the internal cavity from dissipating for a certain period of time. The cavity is in a sealed state, which is used to visually check the effectiveness of the sealing and safe use.

[0047] In the present invention, by first pressing the pressing plate 306, the soft glue folding cavity 305 is stored in the fixed frame 304, and the buckle 303 on the fixed frame 304 is fastened and fixed with the card slot 302 on the pressing frame 301. When the soft glue folding cavity 305 is folded and stored, the air inside is squeezed toward the front transparent soft film 307 inside the front mobile phone case 2 to make it bulge. The bulged front transparent soft film 307 keeps the air in the internal cavity from dissipating for a certain period of time. The cavity is in a sealed state, which is used for visually checking the effectiveness of the sealing and safe use. Therefore, the waterproof mobile phone protective case has a self-testing sealing device, which can be used for the mobile phone waterproof protective case to self-test the waterproof sealing of the mobile phone waterproof protective case when in use, effectively solving the problem of using the mobile phone waterproof protective case when it has waterproof sealing performance, and preventing the mobile phone from being damaged by water when the waterproof performance of the mobile phone waterproof protective case is weakened or fails, thereby better improving the effective use rate of the mobile phone waterproof protective case product.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
