It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please also read Figures 1 to 4 Now, a protective film provided by the present invention is described. The protective film comprises a protective layer 1, a use layer 2, a release layer 3 and a release layer protective film 4 which are stacked and connected in sequence; the release layer 3 comprises a first portion 31 whose one end face is connected to a part of the structure of the use layer 2 and whose other end face is connected to a part of the structure of the release layer protective film 4, and a second portion 32 arranged adjacent to the first portion 31; the second portion 32 has one end face connected to another part of the structure of the use layer 2 and whose other end face is connected to another part of the structure of the release layer protective film 4.

[0024] During use, first separate the release layer protective film 4 from the other structures of the protective film, and then use the release layer 3 to contact the end surface of the release layer protective film 4 with the screen of the device to be filmed. Then lift up the other structures of the protective film from one end to separate the second part 32 from the screen of the device to be filmed, and then remove the second part 32 so that the overlapping part of the use layer 2 and the second part 32 is connected to the screen of the device to be filmed. Then lift up the other structures of the protective film from the other end to separate the first part 31 from the screen of the device to be filmed, and then remove the first part 31 so that the overlapping part of the use layer 2 and the first part 31 is connected to the screen of the device to be filmed. Then remove the protective layer 1 to complete the filming operation.

[0025] Compared with the prior art, the protective film provided by the present invention divides the release layer 3 into two parts. During the film pasting process, the release layer 3 is first used to accurately fit the screen of the device to be pasted, and then the first part 31 and the second part 32 are removed in sequence, thereby achieving high efficiency, accuracy, and excellent film pasting effect. During the process of removing the first part 31, the second part 32 is in a connected state with the screen of the device to be pasted, which can ensure that the portion where the protective layer 2 overlaps with the second part 32 can accurately correspond to the screen of the device to be pasted, and can ensure that no bubbles are generated when the portion where the protective layer 2 overlaps with the second part 32 and the screen of the device to be pasted are pasted. Similarly, the same effect can be achieved when the portion where the protective layer 2 overlaps with the first part 31 and the screen of the device to be pasted is pasted. Thus, an excellent film pasting effect is guaranteed.

[0026] As a specific implementation of the embodiment of the present invention, please refer to Figures 1 to 4 , the protective layer 1, the use layer 2, the release layer 3 and the release layer protective film 4 are bonded in sequence. Specifically, from top to bottom, the protective layer 1, the use layer 2, and the release layer 3 have adhesive surfaces on their bottoms. The protective layer 1, the use layer 2, the release layer 3 and the release layer protective film 4 have the same structure, shape and size. The release layer protective film 4 and the protective layer 1 can effectively protect the use layer 2 and the release layer 3 through the cooperation of the release layer protective film 4 and the protective layer 1.

[0027] As a specific implementation of the embodiment of the present invention, please refer to Figures 1 to 4 The protective layer 1 includes a protective layer body 12 and a first positioning portion 11 detachably connected to or adjacent to the protective layer body 12. The use layer 2 includes a use layer body 22 and a second positioning portion 21 detachably connected to or adjacent to the use layer body 22; the structure and size of the second use layer body 22 are the same as those of the protective layer body 12. A third positioning portion 33 is connected to the first portion 31. The first portion 31 is arranged in contact with the second portion 32, and the shape and size formed when the first portion 31 and the second portion 32 are in contact are the same as those of the use layer body 22. The release layer protective layer 4 includes a release layer body 42 and a fourth positioning portion 41 detachably connected to the release layer body 42.

[0028] In this embodiment, the connection between the first portion 31 and the third positioning portion 33 is a fixed connection. The connection between the release layer body 42 and the fourth positioning portion 41 is a fixed connection.

[0029] During use, first connect the positioning body that matches the positioning structure of the protective film to the device to be pasted. Then separate the release layer protective film 4 (including the release layer body 42 and the fourth positioning part 41) from the other structures of the protective film, and then use the third positioning part 33 to connect with the positioning body, so that the end faces of the first part 31 and the second part 32 that contact the release layer protective film 4 accurately correspond to and contact the screen of the device to be pasted. Then lift up the other structures of the protective film from one end, so that the second part 32 is separated from the screen of the device to be pasted, and then remove the second part 32 so that the overlapping part of the use layer 2 and the second part 32 is connected to the screen of the device to be pasted. Then, the other structures of the protective film are lifted from the other end to separate the first part 31 from the screen of the device to be filmed, and then the first part 31 is removed (when removing the first part 31, the third positioning part 33 will be separated from the positioning body, the second positioning part 21 will be separated from the main body 22 of the use layer, and the first positioning part 12 will be separated from the main body 12 of the protective layer) so that the part where the use layer 2 overlaps with the first part 31 is connected to the screen of the device to be filmed. Then remove the protective layer 1 to complete the filming operation.

[0030] As a specific implementation of the embodiment of the present invention, please refer to Figures 1 to 4 The release layer protective film 4 is provided with a light-isolating structure. The light-isolating structure can prevent light from directly irradiating the adhesive surface of the release layer 3, and can delay the aging of the adhesive surface, thereby effectively ensuring the service life of the protective film.

[0031] As a specific implementation of the embodiment of the present invention, please refer to Figures 1 to 4 The protective layer 1 is provided with a quick-release structure 5. The quick-release structure 5 facilitates the removal of the protective layer 1. It can also avoid the problem of adversely affecting the use layer body 22 during the removal of the protective layer 1, thereby affecting or even reducing the film-sticking effect.

[0032] As a specific implementation of an embodiment of the present invention, a film pasting assembly includes a protective film as described in any one of the above items, and also includes a positioning body adapted to the positioning structure of the protective film. The positioning body can also be connected to the device to be pasted.
