SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cell-phone protection film that prevents dust in order to solve above-mentioned problem to solve among the prior art present protection film surface and correspond earphone department and set up logical groove, do not possess dustproof function, the dust is piled up in the earphone department of cell-phone easily, influences the result of use technical problem such as cell-phone. The utility model provides an among a great deal of technical scheme preferred technical scheme can play the effect of filter screen through setting up evenly distributed's listening cylinder hole when guaranteeing to pass the sound to play dustproof function, avoid the dust to cause handset earphone to block up, technical effect such as excellent in use effect, see the explanation below for details.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a pair of cell-phone protection film that prevents dust, including the tempering layer, the tempering layer dorsal part is pasted and is had the adhesive linkage, the adhesive linkage runs through with cell-phone earphone correspondence department and is provided with logical groove, tempering layer surface evenly run through be provided with lead to the tin bore that the groove corresponds the intercommunication.

Adopt above-mentioned dustproof protection film of cell-phone, during the use, make it is corresponding with mobile phone handset to lead to the groove, through the adhesive linkage will the tempering layer pastes on the screen of cell-phone, through lead to the groove and make it is connected with mobile phone handset to listen the bobbin bore, simultaneously through evenly distributed listen the bobbin bore to play the filter screen effect, play dustproof effect when guaranteeing to answer the phone, avoid the dust to pile up and block up mobile phone handset, excellent in use effect.

Preferably, the tin hole is in a conical structure, and the large-diameter end of the tin hole is communicated with the through groove.

Preferably, a groove is formed in the back side of the toughening layer, the groove is communicated with the earphone hole, and the inner wall of the groove is flush with the inner wall of the through groove.

Preferably, the side surfaces and corners of the toughened layer are embedded with reinforcing wires.

Preferably, the lateral surface of the toughening layer is provided with a fluorescent layer.

Preferably, the edge of the toughened layer is provided with a positioning corner protector.

Has the advantages that: through setting up evenly distributed's tin bore, can play the effect of filter screen when guaranteeing to pass the sound to play dustproof function, avoid the dust to cause cell-phone earphone to block up, excellent in use effect.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

fig. 2 is an enlarged schematic cross-sectional view of fig. 1.

The reference numerals are explained below:

1. a toughening layer; 101. a can hole; 102. a groove; 2. positioning a corner protector; 3. an adhesive layer; 301. a through groove.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the utility model provides a cell-phone protection film that prevents dust, including the tempering layer 1, the 1 dorsal part of tempering layer is pasted and is had adhesive linkage 3, and adhesive linkage 3 runs through with cell-phone earphone correspondence department and is provided with logical groove 301, and tempering layer 1 surface evenly runs through and is provided with the earphone hole 101 that corresponds the intercommunication with logical groove 301.

As an optional implementation manner, the earpiece hole 101 is in a tapered structure, and the large-diameter end of the earpiece hole is communicated with the through groove 301, so that the sound of the mobile phone earpiece conveniently penetrates out through the earpiece hole 101, and meanwhile, the dust filtering effect of the earpiece hole 101 can be improved.

The groove 102 is formed in the back side of the tempered layer 1, the groove 102 is communicated with the earphone hole 101, the inner wall of the groove 102 is flush with the inner wall of the through groove 301, and therefore the groove 102 enables a cavity to be formed between the tempered layer 1 and a mobile phone earphone, and therefore sound of the mobile phone earphone can conveniently penetrate out of the earphone hole 101.
