Description

Technical Field

[0001] The utility model belongs to the technical field of film sticking tools, and in particular relates to a film sticking device adapted to mobile terminals of multiple sizes. Background Art

[0002] At present, mobile electronic products such as mobile phones and tablet computers have become one of the most important communication tools for people. For example, during the use of mobile phones, their screens are easily scratched and scratched, which affects the display effect and aesthetics of the mobile phone screen. Therefore, in order to protect the screen and prevent scratches, most users will apply a protective film on the screen of the mobile phone to protect it during use. When applying a film to a mobile phone, it is difficult to accurately position the protective film and the mobile phone screen manually without the help of tools. Therefore, film-applying tools that assist in film-applying have appeared on the market, which use tools to achieve the positioning of the mobile phone and the protective film.

[0003] In order to improve the quality and convenience of film pasting, devices capable of dust-free film pasting have appeared in the market. For example, the existing patent with application number CN202321887916.4 discloses a mobile phone film pasting device, including a first box body and a second box body that are rotatably connected. The first box body is assembled on one side of the second box body. The first box body and the second box body are relatively protruded with two abutting and matching fixing parts. The fixing parts enclose a closed space for placing a mobile phone and a mobile phone film. The first fixing part of the first box body is provided with a strip groove. One end of the mobile phone film is fixed to the first box body, and the other end extends out of the strip groove. When in use, the user pulls the release film extending out of the strip groove to separate the main film body and the release film, so that the main film body can be adsorbed and connected with the mobile phone screen. In this process, the first box body and the second box body always remain in a buckled state, and external dust cannot enter the closed space, achieving the effect of dust prevention during the use of the mobile phone film pasting device, and improving the success rate and aesthetics of mobile phone film pasting.

[0004] However, the mobile phone film applicator disclosed in the above patent can only adapt to mobile phones of specific sizes and cannot be shared. When a user has multiple mobile phones of different models, he needs to equip himself with multiple mobile phone film applicators of different models, which has the problems of high cost and inconvenience in use.

[0049] Furthermore, a positioning column 611 for positioning the protective film 3 is also provided on the top of the third limiting member 61 .

[0050] Furthermore, when the box cover 12 is closed with the box body 11, a bottom film clamping opening 13 is formed between the box cover 12 and the box body 11. The protective film 3 of the present application includes a positioning film, a tempered film, and a release film. Before applying the film, the screen of the mobile terminal 2 is first placed upwards on the clamping position 4 and clamped, the protective film 3 is placed on the mobile terminal 2, the positioning film is hung on the positioning column 611, the box cover 12 is closed, one end of the release film passes through the bottom film outlet and is exposed outside the box body 11, and the pressing part is pressed against the screen of the mobile terminal 2. When applying the film, the release film is pulled out of the box body 11, the pressing part presses the tempered film against the screen, and exhausts air to both sides with the pressing part as the dividing line, so as to realize automatic film application.

[0051] Furthermore, a scraper 10 is installed on the inner side of the box cover 12. The scraper 10 is fixed to the inner side of the box cover 12 by means of magnetism, bonding, snap-on connection, etc. When bubbles exist after film application, the scraper 10 can be used to remove the bubbles.

[0052] Compared with the existing film sticking tools, the film sticking device of the present invention can form a clamping position 4 by combining the first limit member 51, the second limit member 52, the third limit member 61 with the inner wall of the box body 11, and the mobile terminal 2 is limited and clamped by the first limit member 51, the second limit member 52, and the third limit member 61. The first limit member 51 and the second limit member 52 can be movable to adjust the lateral size of the clamping position 4, and the third limit member 61 can be movable to adjust the longitudinal size of the clamping position 4, so as to achieve the size adjustment of the clamping position 4 and adapt to mobile terminals 2 of different sizes; the first limit member 51 and the second limit member 52 can be linked through the first transmission assembly 53, and only one of them needs to be moved to realize the movement of the two towards or away from each other, realize the coordinated action of the two, and the adjustment is more convenient and quick.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
