[0040] Please combine Figure 1 - Figure 3 The first embodiment of the utility model provides a film applicator 1, which is used to apply a protective film 3 to a screen 21 of an electronic device 2. The protective film 3 includes a film body 31 and a positioning film 32 and a release film 33 respectively attached to both sides of the film body 31. A handle 331 is provided on the release film 33. The film applicator 1 includes a frame 11 and a back plate 10. The frame 11 and the back plate 10 are together enclosed to form a accommodating cavity 12 for fixing the electronic device 2; a pressing strip 101 is provided in the back plate 10 along the width direction of the back plate 10; a pull-out opening 111 is provided on one side of the frame 11 along the width direction of the accommodating cavity 12, a convex block 112 is provided in the pull-out opening 111, and a snap-in opening 3311 is provided on the handle 331 corresponding to the convex block 112; when the snap-in opening 3311 is snapped with the convex block 112, the center line of the handle 331 in the length direction is parallel to one side of the frame 11 in the length direction.

[0041] It can be understood that the protrusion 112 is correspondingly arranged with the bayonet 3311, and the alignment of the handle 331 is ensured during the installation of the film. After the bayonet 3311 is engaged with the protrusion 112, the center line of the handle 331 in the length direction is parallel to one side of the length direction of the frame 11, that is, the length direction of the handle 331 is parallel to the length direction of the frame 11, and the handle 331 and one side of the frame 11 are aligned and parallel, providing operational consistency when pulling the handle 331, ensuring that the position and direction of the handle 331 are symmetrical and stable in the structure of the film applicator 1; when the protective film 3 is installed, the film applicator 1 is buckled onto the screen 21 of the electronic device 2. When the pressure strip 101 is pressed against the positioning film 32, the handle 331 is clamped between the release film 33 and the screen. Since the handle 331 has been aligned during the film installation process, the handle 331 will also be clamped in the correct position between the release film 33 and the screen without offset or misalignment. This ensures that the user can pull out the handle 331 in the positive direction, prevents the handle 331 from causing the release film 33 to deflect, and avoids the release film 33 from skewing, folding or scratching the protective film 3 or the screen. By maintaining the accuracy and stability of the operation, the integrity and quality of the screen and protective film 3 can be protected to the greatest extent.

[0042] Specifically, see Figure 1 The pull-out opening 111 includes a handle pull-out opening 1111 and a release film pull-out opening 1112 . The handle pull-out opening 1111 is connected to the release film pull-out opening 1112 , and the protrusion 112 is disposed in the handle pull-out opening 1111 .

[0043] Furthermore, the release film drawing opening 1112 is arranged close to the accommodating cavity 12 , while the handle drawing opening 1111 is arranged away from the accommodating cavity 12 , and limiting structures 114 are arranged on both sides of the drawing opening 1111 along the width direction of the handle drawing opening 1111 .

[0044] Furthermore, the ratio of the width of the handle draw-out opening 1111 to the width of the handle 331 is 1 / 2-5 / 6.

[0045] The film applicator 1 is buckled downward, the protective film 3 is installed in the accommodating cavity 12, and the handle 331 passes through the pull-out opening 111. When the protective film 3 is installed but the film applicator 1 is not buckled to the screen 21 of the electronic device 2, since the ratio of the width of the handle pull-out opening 1111 to the width of the handle 331 is 1 / 2-5 / 6, the handle 331 is restricted in the release film pull-out opening 1112, and the handle 331 naturally hangs down due to gravity and approaches the handle pull-out opening 1111, but is restricted by the limiting structure 114 and does not completely fall into the handle pull-out opening 1111. At this time, the bayonet 3311 is engaged with the protrusion 1011, and the center line of the handle 331 in the length direction is parallel to one side of the length direction of the frame 11. The bayonet 3311 has a positioning function of aligning the handle 331 and the film applicator 1 in parallel during the installation process of the protective film 3.

[0046] Furthermore, the back plate 10 includes at least one limiting portion 102 extending out of the accommodating cavity 12 , and the drawing opening 111 is arranged away from the limiting portion 102 .

[0047] Specifically, an anti-drop structure 1021 is provided on the limiting portion 102 , and a positioning column 1022 is also provided on the limiting portion 102 .

[0048] Furthermore, a hook-shaped portion is provided at the top of the anti-slip structure 1021 .

[0049] Specifically, the positioning film 32 is provided with an anti-slip hole 322 corresponding to the anti-slip structure 1021, and its shape and position are adaptively arranged with the anti-slip structure 1021. The hook-shaped portion can be inserted into the other side of the protective film 3 through the anti-slip hole 322 to firmly fix the protective film 3 on the film applicator 1. The positioning film 32 is also provided with a positioning hole 321. The positioning hole 321 cooperates with the positioning column 1022 to fix the protective film 3. The positioning hole 321 and the positioning column 1022 are aligned for installation to ensure that the protective film 3 remains in the correct film-applying position, and to ensure that the protective film 3 and the screen 21 of the electronic device 2 are facing each other during film application to prevent the protective film 3 from being crookedly applied.

[0050] Furthermore, the pressing strip 101 has a protrusion 1011 on one side of the accommodating cavity 12, and the thickness of the protrusion 1011 is 2 mm-5 mm.

[0051] Specifically, the protrusion 1011 is elastic and can be made of materials such as silicone, sponge or rubber.

[0052] Specifically, a positioning hole 321 corresponding to the positioning column 1022 is formed on the positioning film 32 .

[0053] The film body 31 is attached to the screen of the electronic device 2 by the resilience of the pressing strip 101. The specific process is: the protective film 3 is fixed on the film applicator 1 through the positioning hole 321 and the positioning column 1022 and the anti-slip structure 1021 cooperates with the anti-slip hole 322 and aligns the center line direction of the handle 331 to be parallel to the direction of the frame 11, wherein the alignment of the center line direction of the handle 331 to be parallel to the direction of the frame 11 is achieved by aligning the protrusion 112 on the pull-out opening 111 with the snap-on 3311 on the handle 331, and then the film applicator 1 is buckled to the electronic device 2, wherein the screen of the electronic device 2 faces the accommodating cavity 12. Align the edges of the screen and the protective film 3. After the protective film 3 and the electronic device 2 are fixed, peel off the release film 33 by pulling out the handle 331 of the release film 33 at the pull-out opening 111. Then, the protrusion 1011 on the pressing strip 101 applies pressing pressure to the screen 21 of the electronic device 2, so that the protective film 3 is better attached to the screen. There is no need to manually apply more pressing pressure, and the film body 31 can be evenly and evenly attached to the screen. Then, peel off the positioning film 32 to complete the film application process.

[0054] Furthermore, a first observation window 103 is provided on one side of the back plate 10 close to the limiting portion 102 , and the pressing strip 101 is disposed close to the first observation window 103 .

[0055] Furthermore, a second observation window 104 is provided on the back plate 10 near the drawer opening 111 and along the width direction of the back plate 10 .

[0056] It can be understood that the first observation window 103 and the second observation window 104 help the user to better observe the attachment status of the film body 31 .

[0057] Furthermore, an operation notch 113 is formed on a side of the frame 11 away from the drawer opening 111 .

[0058] It can be understood that the operation notch 113 is used to provide the user with an opportunity to take and put the mobile phone. Specifically, for an electronic device 2 with buttons on the side, setting the operation notch 113 at the corresponding button position can make the contact between the electronic device 2 and the film applicator 1 closer, providing a better film application effect.

[0059] Furthermore, the protrusion 112 , the frame 11 and the back plate 10 are integrally formed.

[0060] Understandably, one-piece molding uses injection molding technology, improves the stability and durability of the product, allows for a more integrated and compact design, and helps reduce the volume and size of the product.

[0061] For further information, see Figure 2 A side of the back plate 10 away from the accommodating cavity 12 is provided with an anti-slip stripe 105 .

[0062] See also Figure 4 The second embodiment of the utility model provides a protective film 3, which includes a film body 31 and a positioning film 32 and a release film 33 respectively attached to two sides of the film body 31.

[0063] Continue reading Figure 5 The third embodiment of the present invention provides a film sticking assembly 4, comprising the aforementioned protective film 3 and the aforementioned film sticking device 1.

[0064] It is understandable that different types of film applicators 1 and protective films 3 are required to match electronic devices 2 with different screen sizes. By combining the film applicator 1 and the protective film 3, the user can save the steps of matching and installing the film applicator 1 and the protective film 3, and can also avoid the situation where the user does not align the film applicator 1 and the protective film 3 when matching by himself, thus providing a better user experience.
