Description

Technical Field

[0001] The utility model relates to the technical field of protective film positioning, in particular to an abrasion-resistant protective film and a positioning mechanism for the protective film. Background Technique

[0002] With the development of the information age, mobile phones are more and more widely used. In order to better protect and use mobile phones and extend their service life, it is usually necessary to apply a film to the mobile phone screen. When the mobile phone accidentally drops, the protective film can prevent the mobile phone screen from breaking, playing a good protective role. Whether the protective film can be accurately pasted on the mobile phone screen determines the beauty of the mobile phone.

[0003] The abrasion resistance of mobile phone protective films is poor and they are extremely easy to be damaged after friction with other objects, resulting in the exposure of the mobile phone screen and damage to the mobile phone screen. The current mobile phone protective films still tend to be traditional, and the film pasting work is often completed manually, with a relatively high labor cost for film pasting. Therefore, many consumers choose to buy online and paste the film by themselves. However, when pasting the film by themselves, due to the lack of proficiency in operation, it is often pasted crooked, affecting the later use and beauty of the mobile phone. In order to meet the expected film pasting standard in their hearts, it is often necessary to paste the film repeatedly and multiple times. This process is likely to make the protective film stick to dust, and it will also cause waste of mobile phone protective films, increasing the film pasting cost. The time consumed in the film pasting process is also relatively long. At present, there are some film pasting and film pasting methods with molds, but these products are dedicated to special machines and cannot be compatible with mobile phones of different models. Content of the Utility Model

In order to meet the expected film pasting standard in their hearts, it is often necessary to paste the film repeatedly and multiple times. This process is likely to make the protective film stick to dust, and it will also cause waste of mobile phone protective films, increasing the film pasting cost. The time consumed in the film pasting process is also relatively long. At present, there are some film pasting and film pasting methods with molds, but these products are dedicated to special machines and cannot be compatible with mobile phones of different models, and to propose an abrasion-resistant protective film and a positioning mechanism for the protective film.

One end of the bottom plate 1 is fixed with a first side plate 2, and a second side plate 3 is slidably installed on the bottom plate 1. The second side plate 3 is fixed to the bottom plate 1 through an L-shaped plate 5. A row of first through holes 101 is provided on the bottom plate 1, and the L-shaped plate 5 is fitted in the row of first through holes 101. Adjusting mechanisms 6 are provided on both the first side plate 2 and the second side plate 3. The adjusting mechanism 6 includes a first ring 601 fixed to the first side plate 2 and the second side plate 3. A bearing 602 is installed inside the first ring 601, and a threaded rod 603 is installed on the inner ring of the bearing 602. Two threaded cylinders 604 are threadedly fitted on the threaded rod 603. The protective film main body 8 is arranged between the two threaded cylinders 604 of the threaded rod 603, ensuring that the protective film main body 8 can move up and down through the adjusting mechanism 6, and at the same time ensuring the positioning operation of the protective film main body 8, so that the protective film main body 8 can completely fit on the mobile phone main body 7 to avoid deviation.

[0026] Third side plates 4 are fixed to both the first side plate 2 and the second side plate 3. The first side plate 2 and the second side plate 3 have the same structure. A groove 301 is provided on the second side plate 3, and the adjusting mechanism 6 is arranged inside the groove 301. A sliding groove 304 is provided on the bottom surface of the second side plate 3, and the sliding groove 304 is slidably fitted on the bottom plate 1. Second through holes 302 and third through holes 303 are respectively provided at both ends of the sliding groove 304, and the L-shaped plate 5 is fitted on the bottom plate 1 through the second through holes 302 and the third through holes 303. The second side plate 3 can slide on the bottom plate 1, so that the distance between the first side plate 2 and the second side plate 3 can be adjusted according to the size of the user's mobile phone main body 7. One end of the mobile phone main body 7 is attached to the third side plates 4 of the first side plate 2 and the second side plate 3, ensuring that the first side plate 2 and the second side plate 3 clamp the mobile phone main body 7.

[0027] A wear-resistant protective film for a positioning mechanism of a protective film, comprising a protective film main body 8. On the protective film main body 8, a first film body 801 and a second film body 802 are respectively arranged. Both the first film body 801 and the second film body 802 can be separated from the protective film main body 8. At both ends of the second film body 802, second circular rings 803 are arranged. The second circular rings 803 are sleeved on the adjusting mechanism 6. Two threaded cylinders 604 are respectively arranged at both ends of the second circular ring 803. The protective film main body 8 includes a base layer 805. The bottom surface of the base layer 805 is connected with an adhesive layer 804, and the top surface of the base layer 805 is connected with a first wear-resistant coating 806.

According to the size of the mobile phone main body 7, slide the second side plate 3 on the bottom plate 1 so that the second side plate 3 can be attached to the other side of the mobile phone main body 7. Pass the L-shaped plate 5 through the second through hole 302 of the second side plate 3 into the first through hole 101 of the bottom plate 1, so that one end of the L-shaped plate 5 can be fitted into the third through hole 303 of the second side plate 3, thereby ensuring that the second side plate 3 is installed on the bottom plate 1. At the same time, the third side plate 4 of the second side plate 3 is also attached to one end of the mobile phone main body 7, so that the mobile phone main body 7 can be limited and fixed by the first side plate 2 and the second side plate 3. After the mobile phone main body 7 is fixed, thread a threaded cylinder 604 onto the threaded rod 603 of the adjusting mechanism 6, separate the first film body 801 from the protective film main body 8. At the same time, the second circular ring 803 of the second film body 802 on the protective film main body 8 is sleeved on the threaded cylinder 604 of the threaded rod 603. Then thread another threaded cylinder 604 onto the threaded rod 603 so that the second circular ring 803 is arranged between the two threaded cylinders 604. Rotate the threaded rod 603 so that the protective film main body 8 moves up and down to ensure that the protective film main body 8 can be attached to the mobile phone main body 7, realizing the positioning operation of the protective film main body 8. After the protective film main body 8 is attached to the mobile phone main body 7, rotate the threaded rod 603 again so that the two threaded cylinders 604 drive the second circular ring 803 and the second film body 802 to be separated from the protective film main body 8, completing the overall use operation.
