It is to be appreciated that term " length ", " width ", "upper", "lower", "front", "rear", "left", "right", "vertical", The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom" "inner", "outside" is that orientation based on the figure or position are closed System, is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning are necessary It with specific orientation, is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

In addition, term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance Or implicitly indicate the quantity of indicated technical characteristic.Define " first " as a result, the feature of " second " can be expressed or Implicitly include one or more of the features.The meaning of " plurality " is two or two in the description of the present invention, More than, unless otherwise specifically defined.

Also referring to Fig. 1 to Fig. 7, now protective film provided by the utility model is illustrated.Protective film includes basement membrane 1, silica gel adhered layer 2, layer of silica gel 3 and feel oil reservoir 4；The back side of layer of silica gel 3 is equipped with embedded groove 31, and basement membrane 1 is embedded in embedded groove In 31, silica gel adhered layer 2 covers the back side of basement membrane 1 and the back side of layer of silica gel 3 simultaneously, and feel oil reservoir 4 is covered in the layer of silica gel 3 One side far from the basement membrane 1；Silica gel adhered layer 2 can wash repetition stickup, and feel oil reservoir 4 can be automatically repaired.

Protective film provided by the utility model, compared with prior art, by being set to the silica gel adhered layer 2 at 1 back side of basement membrane, Convenient for being bonded between protective film and the equipment for needing pad pasting, and the washable silica gel adhered layer 2 for repeating to paste, realize protective film It repeatedly pastes, practicability is good；Pass through having shock resistance and be automatically repaired function in one side of the layer of silica gel 3 far from the basement membrane 1 Feel oil reservoir 4, by anti-dazzle, anti-scratch, the multiple functions such as shock resistance are integrated in one, and not only antiglare effect is good, do not lose it is high thoroughly Photosensitiveness, while there is splendid shock resistance again and be automatically repaired performance；Basement membrane 1 is embedded in layer of silica gel 3, on the one hand, improve The safety of basement membrane 1, on the other hand, so that basement membrane 1 is substantially all covered by layer of silica gel 3 in addition to the side of fitting silica gel adhered layer 2 Lid, to improve the protective value of protective film.

Further, a kind of specific implementation also referring to Fig. 1 and Fig. 3, as protective film provided by the utility model Mode, protective film are equipped with the through-hole 5 for exposed equipment vocal hole, and layer of silica gel 3 is partially formed as the wall surface of through-hole 5.? Layer of silica gel 3 is covered on the wall of through-hole 5, improves the security performance of 5 range of through-hole, is reduced and is hurt because of the damage of the basement membrane 1 of 5 range of through-hole The case where victimization body, occurs.

Further, layer of silica gel 3 with a thickness of 0.3mm.The thickness for reducing protective film, so that protective film is more frivolous.

Further, basement membrane 1 be glass-film, basement membrane 1 with a thickness of 0.25mm.By the way that basement membrane 1 is set as glass-film, improve The hardness of protective film entirety, and pass through the cooperation of glass-film and pellosil, so that not only hardness is high but also cushion performance for protective film It is good.

Further, the general thickness of basement membrane 1 and layer of silica gel 3 be 0.3mm, layer of silica gel 3 be located at it is epilamellar with a thickness of 0.05mm.The thickness for reducing protective film so that protective film is more frivolous, layer of silica gel 3 on basement membrane 1 with a thickness of 0.05mm, both It ensures the normal use of the equipment of fitting protective film, and basement membrane 1 is made to be difficult to be worn.

Specifically, after basement membrane 1 is embedded in layer of silica gel 3, the general thickness of basement membrane 1 and layer of silica gel 3 is 0.3mm, the depth of embedded groove Degree is 0.25mm.

Further, feel oil reservoir 4 with a thickness of 0.5 μm -1 μm.The thickness for reducing protective film, so that protective film is lighter It is thin；Feel oil reservoir 4 makes protective film also have the function of anti-fingerprint, and the surface of the protective film is smooth, so that user is grasping It is fitted with more smooth comfortable when the equipment of the protective film.

Further, silica gel adhered layer 2 with a thickness of 5 μm -20 μm.The thickness for reducing protective film, so that protective film is more It is frivolous.

Further, referring to Fig. 7, a kind of specific embodiment as protective film provided by the utility model, silica gel Multiple groups glass microballoon 6, the setting of the interval of multiple groups glass microballoon 6 are equipped in layer 3.Multiple groups glass microballoon 6 is set, the hard of protective film is improved Degree so that the protective value of protective film is stronger, and makes extraneous temperature be difficult to be transferred in equipment by protective film.

Further, referring to Fig. 7, a kind of specific embodiment as protective film provided by the utility model, adjacent Buffer cavity 7 is equipped between glass microballoon 6.Buffer cavity 7 is set, the cushion performance of layer of silica gel 3 is improved, so that protective film has Better cushion performance.

Further, referring to Fig. 7, a kind of specific embodiment as protective film provided by the utility model, glass Microballon 6 is located at the top of buffer cavity 7, and buffer cavity 7 is arranged close to basement membrane 1.By the way that buffer cavity 7 is arranged close to basement membrane 1, So that protective film weakens the impact force when by impact force, through layer of silica gel 3 itself, then further by buffer cavity 7 Impact force is weakened, the cushion performance of layer of silica gel 3 is improved；By the way that glass microballoon 6 to be set to the top of buffer cavity 7, so that The directly extraneous contact of glass microballoon 6, not only enables protective film to have higher hardness but also makes the heat other than protective film Degree is difficult to have an impact to equipment by protective film.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
