[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] Embodiment 1 of the protective film without release film of the utility model

[0039] Please refer to Figure 1-Figure 2 The protective film without release film of the utility model includes: a protective film roll 1, and the protective film roll 1 is formed by connecting a plurality of protective film bodies 101 end to end to form a continuous winding structure, and the protective film body 101 of the outer layer of the winding structure and the protective film body 101 of the inner layer are connected to each other by pasting. When in use, the required protective film body 101 can be removed by tearing, so that no release film is required to reduce the waste of resources.

[0040] Further, such as Figure 1-Figure 2 As shown, a half-cut separation line 104 is arranged between two adjacent protective film bodies 101. The half-cut separation line 104 is used to assist in the separation of the protective film bodies 101. The arrangement of the half-cut separation line 104 makes the separation of the two protective film bodies 101 more convenient, thereby improving the production efficiency. Secondly, the half-cutting technology can ensure that the separation process is accurate and error-free, thus avoiding unnecessary damage to the protective film bodies 101. In addition, the half-cutting can ensure that the protective film roll 1 still maintains its original functionality and aesthetics after separation, thus providing a good guarantee for subsequent use.

[0041] Further, such as Figure 1-Figure 3 As shown, a tearing handle 103 is provided on one side of the protective film body 101. The tearing handle 103 is used to assist in tearing off the protective film body 101. When in use, the tearing handle 103 is grasped to tear off the protective film body 101, so that a piece of the protective film body 101 is separated; this design saves a piece of release film, greatly reduces the material cost, and avoids the waste of film material, which is very environmentally friendly. The tearing handle 103 has a color, and the color setting can facilitate the judgment of whether the protective film body 101 is torn off from the display module;

[0042] Each protective film body 101 has the same shape and size to ensure the regularity and stability of the winding structure; and such a winding structure not only has a regular appearance, but can also maintain stable performance during use, effectively extending the service life of the product.

[0043] Further, such as Figure 4As shown, the protective film body 101 includes an anti-blue light layer 1011, the anti-blue light layer 1011 is connected to an anti-glare layer 1012, the anti-glare layer 1012 is connected to a substrate layer 1013, and the substrate layer 1013 is connected to an adhesive layer 1014. The anti-blue light layer 1011 is mainly used to protect the eyes from high-energy short-wave blue light. This blue light usually comes from the screen of an electronic device. Long-term exposure to this light may cause damage to the eyes, such as retinal damage, and may even induce the production of skin melanin, leading to skin problems; the anti-glare layer 1012 is mainly used to reduce the light reflected and scattered by the screen to avoid visual fatigue when used in a strong light environment.

[0044] Further, such as Figure 1 As shown, it also includes a winding core 2, and the protective film roll 1 is wound on the outer surface of the winding core 2. The winding core 2 can be used to support the protective film roll 1 so that the protective film roll 1 can maintain a rolled shape.

[0045] Further, such as Figure 1-Figure 2 As shown, an auxiliary film 102 is provided on the side of the protective film body 101 away from the winding core 2, and a half-cut separation line 104 is also provided between the auxiliary film 102 and the protective film body 101. The setting of the half-cut separation line 104 facilitates fixing the last protective film body 101 after several protective film bodies 101 are wound together.

[0046] When in use, the tearing handle 103 is grasped to tear off the protective film body 101 from the half-cut separation line 104 .

[0047] Embodiment 2 of the protective film without release film of the utility model

[0048] Further, such as Figure 5-Figure 8 As shown, the winding core 2 is connected to a supporting mechanism 3, which is used to support the winding core 2 and assist in tearing off and positioning the protective film body 101. By positioning the protective film body 101 through the supporting mechanism 3, it is easy to find the beginning of the protective film body 101 when it is used again.

[0049] Further, such as Figure 7 As shown, the supporting mechanism 3 includes a base 301, a screw hole 302 is opened in the middle of the base 301, a connecting screw 303 is threadedly connected to the screw hole 302, the winding core 2 is sleeved on the outer surface of the connecting screw 303 and a gap is left between the winding core 2 and the connecting screw 303, the setting of the gap enables the winding core 2 to rotate around the connecting screw 303, and the rotating base 301 separates the screw hole 302 from the connecting screw 303, so that the connecting screw 303 can be inserted into the winding core 2, or the winding core 2 can be removed after use.

[0050] Further, such as Figure 5-Figure 8As shown, a connecting seat 304 is fixedly installed on the top of the connecting screw 303, an extension arm 305 is fixedly installed on one side of the connecting seat 304, and an auxiliary part is movably provided between the extension arm 305 and the connecting seat 304. The connecting seat 304 can cooperate with the base 301 to limit the winding core 2 to prevent the winding core 2 from detaching from the protective film roll 1.

When the protective film body 101 is torn off, the auxiliary plate 309 is pressed on the half-cut separation line 104 to avoid tearing the adjacent protective film body 101 during the tearing process. After the protective film body 101 is torn off, the auxiliary plate 309 indicates the positioning of the subsequent protective film body 101, so that the user can quickly find the beginning position of the protective film body 101 when using it again.

[0052] When in use, rotate the handle 308 to make the threaded rod 307 rotate and drive the auxiliary plate 309 away from the connecting seat 304, and then pull the protective film body 101, rotate the handle 308 in the opposite direction to make the auxiliary plate 309 move toward the connecting seat 304 and press on the protective film body 101 at the rear, and the side of the auxiliary plate 309 is aligned with the half-cut separation line 104, grab the tearing handle 103, and tear the protective film body 101 from the half-cut separation line 104.
