Description

TECHNICAL FIELD

The present application relates to the technical field of film sticking, and in particular to a film-sticking auxiliary device for a mobile phone.

BACKGROUND

Mobile phones have become an indispensable communication tool in people's lives. However, due to the frequent use of mobile phones, the screen of mobile phones is easy to get dirty or even scratched. Generally, mobile phone films (such as tempered glass films) are used to protect the screen of mobile phones. However, when applying tempered glass films, most of them are based on the experience of operators to judge whether the tempered glass films are applied flat and whether they completely cover the mobile phone screen. Such operation may easily cause the tempered glass films to be applied crookedly or require multiple adjustments.

For this reason, Chinese patent CN218499169 U discloses a mobile phone screen film with a pull-strap cleaning function (as shown in FIG. 1), including a tempered film, a tempered film protective film and a hand-tear pull strap. The tempered film protective film is adhered to the surface of the tempered film, and a hand-tear pull strap is provided on the other side of the tempered film protective film. When applying the film, the mobile phone screen film is placed inside the mobile phone positioning frame, and it is ensured that one side of the hand-tear pull strap corresponds to the screen of the mobile phone; and then the mobile phone screen film with the screen film is buckled on the side wall of the mobile phone. At the same time, the hand-tear pull strap is pulled out from the notch at the bottom of the mobile phone positioning frame, which drives the tempered film protective film to be pulled out from between the tempered film and the mobile phone screen. While being pulled out, the tempered film acts on the mobile phone screen to achieve application. During the process of pulling out the tempered film protective film, its adhesive side contacts the mobile phone screen, thereby completing the film application on the mobile phone screen. Although this technology solves the problems of crooked and uneven tempered film application that exist in manual application, it requires the user to press the mobile phone when applying the film, so there is a problem of uneven force; especially the contact part between the tempered film and the mobile phone screen is difficult to bear force, and bubbles are easily left after the film application is completed, resulting in poor film application effect.

As shown in FIG. 2, FIG. 2 is a structural schematic diagram according to the first embodiment of the present application.

This embodiment provides the film-sticking auxiliary device for the mobile phone, including a base plate 1, a cover plate 2 and a connecting plate 3; the base plate 1 and the cover plate 2 are both located on the connecting plate 3; a fold 31 is provided in the middle of the connecting plate 3; the base plate 1 is located below the fold 31, and the cover plate 2 is located above the fold 31. When the connecting plate 3 is turned around the fold 31, the cover plate 2 can be correspondingly buckled and fixed together with the base plate 1.

A lower limit frame 11 is provided on the base plate 1, and the lower limit frame 11 cooperates with the base plate 1 to form a lower accommodation space 12 for placing a mobile phone film and a mobile phone.

The lower limit frame 11 includes two second long frames 111 and two second short frames 112 arranged opposite to each other, and the rectangular frame formed by the second long frame 111 and the second short frame 112 is used to fix the mobile phone. A groove 114 is provided on the two second long frames 111 to facilitate the mobile phone to be taken in and out of the lower limit frame 11. A pull-out groove 115 is provided on the second short frame 112 below. When the mobile phone film is placed in the lower limit frame 11, the hand-tear pull strap can be placed in the pull-out groove 115 and the lower limit frame 11 is exposed.

An upper limit frame 21 is provided on the cover plate 2, which can be buckled with the lower limit frame 11. The upper limit frame 21 cooperates with the cover plate 2 to form an upper accommodation space 22, which corresponds to the lower accommodation space 12; the upper limit frame 21 includes two first long frames 211 and two first short frames 212 arranged oppositely.

A snap-in groove 113 is provided on the outer side of each of the four corners of the lower limit frame 11, and a snap-in column 213 corresponding to the snap-in groove 113 is provided on the inner side of each of the four corners of the upper limit frame 21. When the upper limit frame 21 is correspondingly buckled on the lower limit frame 11, the snap-in column 213 is correspondingly buckled with the snap-in groove 113 to ensure that the lower limit frame 11 and the upper limit frame 21 are firmly and stably buckled.

A first protrusion 221 is provided in the upper accommodation space 22; a second protrusion 121 corresponding to the position of the first protrusion 221 is provided in the lower accommodation space 12. When the cover plate 2 and the base plate 1 are correspondingly buckled, the back cover of the mobile phone to be filmed between the lower limit frame 11 and the upper limit frame 21 abuts against the first protrusion 221, and the mobile phone film in the lower limit frame 11 abuts against the second protrusion 121.
