Embodiment

Below in conjunction with drawings and Examples, the present invention is described in further detail.

The hermetically-sealed construction of mobile phone protecting case, comprises face-piece (1) and drain pan (2), and by in-mould injection technique, the face-piece frame (1-3) of face-piece (1) adopts TPPE material, and the face-piece facial mask (1-4) of face-piece (1) adopts transparent PC material; The drain pan frame (2-7) of drain pan (2) adopts TPU material, and the drain pan facial mask (2-8) of drain pan (2) adopts transparent PC material.

After face-piece (1) injection molded, fingerprint film (1-1) is bonded at the position, hole that face-piece (1) below is corresponding; Be bonded at by receiver waterproof membrane (1-2) on the upper corresponding square hole of face-piece (1), the assembling of face-piece (1) just completes.

After drain pan (2) injection molded, back side miaow head waterproof membrane (2-1) is bonded on position, hole corresponding to drain pan (2) back side, bottom surface miaow head waterproof membrane (2-2) is bonded on the position, hole below drain pan (2), camera eyeglass gum (2-6) is attached on camera eyeglass (2-4), and then on the shooting head bore position adhering on drain pan (2), 3 drain pans location stopple gum (2-5) are attached on 3 drain pans location stopple (2-3), and then on 3 location holes adhering on drain pan (2), the assembling of drain pan (2) just completes.

As shown in Figure 9, this embodiment face-piece frame (1-3) inner side be provided with 2 ring-shaped grooves between A, C, E; 2 annular protrusions B, D are provided with in drain pan frame (2-7) inner side; A, B, C, D, E adopt the design of back-off shape, and B is intercalated into the groove between A, C, and C is intercalated into the groove between B, D, and D is intercalated into the groove between C, E.

As shown in Figure 9:

Groove width between A, C is a, and the present embodiment is got a and is of a size of 1.0 millimeters.

The root thickness of C is b, and the present embodiment is got b and is of a size of 0.8 millimeter; The head thickness of C is c, and because C is back-off shape, therefore the size of c is greater than the size of b, and the present embodiment is got c and is of a size of 1.2 millimeters.

Groove width between C, E is d, and the present embodiment is got d and is of a size of 1.0 millimeters.

The head thickness of B is e, and the present embodiment is got e and is of a size of 1.5 millimeters.

Minimum spacing between B, D is f, and the present embodiment is got f and is of a size of 0.6 millimeter.

The head thickness of D is g, and the present embodiment is got g and is of a size of 1.5 millimeters.

When C is intercalated into the groove between B, D, due to the root thickness b=0.8 millimeter of C, be greater than minimum spacing f=0.6 millimeter between B, D, because C is back-off structure, therefore B, D can clamp the two sides of C thus realize the interference seal of two sides; Owing to being interference fit between C and B, D, may there is the risk of not exclusively sealing in the impact of its reaction force, because this increasing structure A, E; A, E can extrude B, D, and then B, D extrude C again, thus can prevent outer distortion.

In addition, the head thickness g=1.5 millimeter of D, the groove width d=1.0 millimeter between C, E, g>d, can realize the interference seal of groove between D and C, E; The head thickness e=1.5 millimeter of B, the groove width a=1.0 millimeter between A, C, e>a, can realize the interference seal of groove between B and A, C.

In sum, from outside to inside, first sealing is D and C, the interference fit seal that formed between E; The interference fit seal that second sealing is C and B, formed between D; The interference fit seal that three seals is B and A, formed between C; By this three seals, finally reach cocksure sealed waterproof effect.
