[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] ReferenceFigs. 1 to 4 The screen protector provided by this utility model includes a mobile phone, a screen protector, a base 1, a screen protector assembly 2, and a screen protector roller 14. The screen protector has the same structure as the screen protector proposed in the prior art, which is a multi-layer structure. The front and rear ends of the protective film of the screen protector are provided with positioning holes for positioning.

[0029] To prevent the film application assembly 2 from deforming when the film application roller 14 presses against the terminal device, the film application assembly 2 is slidably connected to the upper wall of the base 1 via two sets of sliding rods 7. The film application roller 14 is rotatably connected to the inner upper wall of the film application assembly 2. A set of sliding grooves 6 are provided on the upper wall of the base 1 near the left and right sides. The two sets of sliding rods 7 are respectively fixedly connected between the inner front wall and the inner rear wall of the sliding groove 6. A connecting part 13 is provided on the lower wall of the film application assembly 2 near the left and right sides. The two sets of sliding rods 7 pass through the connecting part 13 and are slidably connected to it. The film application assembly 2 is slidably connected to the base 1 via the connecting part 13 and the sliding rods 7. The cross-section of the two sets of sliding rods 7 is circular. The two sets of sliding rods 7 are stainless steel round rods. The rigidity of the stainless steel round rods ensures that the film application assembly 2 will not be deformed when it moves back and forth, ensuring uniform pressure when the film application roller 14 presses the film against the terminal device and ensuring the quality of film application.

[0030] In order to position the terminal device and guide the movement direction of the screen protector assembly, a groove 3 is provided on the upper wall of the base 1. Multiple sets of baffles 4 are provided on the inner side wall of the groove 3, and the multiple sets of baffles 4 form a receiving area for placing the mobile phone. An indicator structure for guiding the movement direction of the screen protector assembly 2 is provided on the lower inner wall of the groove 3. The indicator structure includes two sets of indicator strips. Both sets of indicator strips are provided on the lower inner wall of the groove 3 and are distributed left and right. The indicator strips are composed of multiple directional indicator marks 5 distributed front and back. The multiple sets of baffles 4 are integrally formed with the base 1 and are used to position the mobile phone. The multiple sets of indicator marks 5 can guide the movement direction of the screen protector assembly 2.

[0031] In order to fix the rear end of the diaphragm, a first opening 101 with vertical penetration is provided on the inner wall of the base 1 and behind the sink 3. A guide seat 10 is fixedly connected to the inner rear wall of the first opening 101. A second opening 11 is provided inside the guide seat 10. A first positioning structure for positioning the rear end of the diaphragm is provided on the inner front wall of the second opening 11. The first positioning structure includes two sets of rear positioning posts 12. Both sets of rear positioning posts 12 are fixedly connected to the inner front wall of the second opening 11. After the positioning hole of the rear end of the diaphragm is fitted with the positioning post 12, it is pulled forward to complete the positioning of the rear end of the diaphragm.

[0032] To prevent the guide seat 10 from being pressed down and causing inaccurate positioning of the rear end of the film, the guide seat 10 is tilted with its rear end lower than its front end. The highest point of the front end of the guide seat 10 is at the same height as the upper wall of the mobile phone placed in the receiving area. Only the rear end of the guide seat 10 is connected to the inner rear wall of the first opening 101, and the front end of the guide seat 10 is tilted upward, making the guide seat 10 elastic. After the film is fitted with the rear positioning post 12 and the front positioning post 9, it is in a taut state. By setting the height of the front end of the guide seat 10 to be the same as the height of the upper wall of the mobile phone, the distance that the guide seat 10 is pressed down can be reduced, ensuring that the rear edge of the film is aligned with the rear edge of the mobile phone, thus improving the film application accuracy.

[0033] To fix the front end of the diaphragm, two sets of positioning seats 8 are fixedly connected to the upper wall of the base 1 and the front side of the sink 3. The two sets of positioning seats 8 are distributed left and right. The upper end of the positioning seat 8 is provided with a second positioning structure for positioning the front end of the diaphragm. The second positioning structure includes two sets of front positioning posts 9. The two sets of front positioning posts 9 are fixedly connected to the upper wall of one set of positioning seats 8. After the positioning hole at the rear end of the diaphragm is fitted with the positioning post 12, it is pulled forward and fitted onto the front positioning post 9. Through the elasticity of the guide seat 10, the diaphragm is tightened, and the front and rear positioning of the diaphragm is completed.

[0034] Working Principle: In this embodiment, the diaphragm structure is consistent with that proposed in the prior art, and is a multi-layer structure. Positioning holes for positioning are provided at both the front and rear ends of the protective film of the patch. The film application assembly 2 is slidably connected to the base 1 via the connecting part 13 and the sliding rod 7. Both sets of sliding rods 7 have circular cross-sections and are made of stainless steel. The rigidity of the stainless steel rods ensures that the film application assembly 2 will not deform when moving back and forth, ensuring uniform pressure when the film application roller 14 presses the film onto the mobile phone, thus ensuring the quality of the film application. Multiple sets of baffles 4 are integrally formed with the base 1 and are used to position the mobile phone. Multiple sets of indicator marks 5 can provide guidance. The function of the moving direction of the film application assembly 2 is that the guide seat 10 is only connected to the rear wall of the inner side of the first opening 101 at its rear end, and the front end of the guide seat 10 is tilted upward, making the guide seat 10 elastic. After the film is put on the rear positioning post 12 and the front positioning post 9, it forms a taut state. By setting the height of the front end of the guide seat 10 to be consistent with the height of the upper wall of the mobile phone, the distance that the guide seat 10 is pressed down can be reduced, ensuring that the rear edge of the film is aligned with the rear edge of the mobile phone, thus improving the film application accuracy. After the positioning hole at the rear end of the film is put on the positioning post 12, it is pulled forward and put on the front positioning post 9. Through the elasticity of the guide seat 10, the film is taut, thus completing the front and rear positioning of the film.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
