Description

TECHNICAL FIELD

[0001] The application belongs to the field of film pasting, and particularly relates to a film pasting structure. BACKGROUND

[0002] Mobile phones, tablets and other devices are one of the most common electronic devices in people's lives. With the continuous progress and innovation of science and technology, smart phones, tablets and other devices have become very popular. People generally add a protective film to the screen of the device in order to protect the screen. The protective film is a cold mounting film that can be used to mount the surface of the body, screen and other tangible objects of a mobile phone, tablet and other device, and there are various types, which can be divided into: peep-proof film, mirror film, AR film, frosted film, high-definition film, scratch-resistant protective film, 3D film, scratch-resistant protective film for the body of a mobile phone, tablet and other device, diamond film, tempered film and the like. When pasting a film on a mobile phone, tablet and other device, the user often uses some auxiliary tools to improve the film pasting success rate. Although the existing auxiliary film pasting tools can quickly and accurately paste the film on the surface of the screen of a mobile phone, tablet and other device, the user still needs to manually press the film with some tools to make the film better adhere to the screen of a mobile phone, tablet and other device. However, the user cannot control the force well when using some existing scraping plates and the like to press the film, which may cause the scraping plate to damage the film or bubbles to appear on the film due to uneven pressing during pressing of the film, and the film pasting operation is very troublesome.

[0003] The mobile phone film positioning device in the comparative file with the patent application number CN201120538319.1 comprises a shell, the shell is provided with a recessed position accommodating a mobile phone and a mobile phone film, the size and shape of the recessed position are matched with the mobile phone and the mobile phone film, positioning grooves are formed at both ends of the recessed position, and the bottom of the positioning groove is provided with a protruding point for positioning the mobile phone film. The utility model also discloses a mobile phone film with a positioning structure matched with the positioning device, the protective layer of the film is provided with a lug corresponding to the positioning groove, and the lug is provided with a positioning hole matched with the protruding point. The mobile phone film positioning device and the mobile phone film with a positioning structure matched therewith in the above comparative file simplify the positioning of the mobile phone film and the mobile phone screen, make the operation of the entire mobile phone film simple, save a large amount of time, and enable an ordinary person to easily complete the operation. However, when the film is pasted by using the mobile phone film positioning device, the user cannot control the force well, which may cause the scraping plate to damage the film or bubbles to appear on the film due to uneven pressing during pressing of the film, and the film pasting operation is still very troublesome.
