[0040] Embodiment one

[0041] As Figure 5 ,Figure 6 As shown in the drawings, the present embodiment proposes a film applicator with a plug-and-slide film fixing structure, which is used for applying a film to a screen of a mobile terminal. The mobile terminal in the present embodiment can be a mobile phone 10, and can also be an electronic device such as a tablet computer, an e-book, a smart watch, etc. For the convenience of structural description of the present embodiment, the length direction of the mobile phone 10 is taken as the length direction, the width direction is taken as the width direction, and the thickness direction is taken as the up-down direction. Each part of the film applicator of the present embodiment is described in the above direction. As shown in the drawings, Figure 1 , Figure 2 The film applicator with the plug-and-slide film fixing structure is used for bonding a protective film 20 to the screen of the mobile phone 10, and the protective film 20 can include a film layer 21 and a tear-away release layer 22. The film layer 21 is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10, and the film layer 21 can be tempered glass. The tear-away release layer 22 is arranged on the film layer 21. In use, the tear-away release layer 22 is pulled away from the film layer 21, and only the film layer 21 is bonded to the surface of the screen of the mobile phone 10.

[0042] As shown in the drawings, Figure 1 , Figure 2 , Figure 3As shown, the embodiment proposes a film applicator with plug-in sliding film fixing structure, which is used for connecting protective film 20. The protective film 20 of the embodiment is provided with clamping grooves 23 at the edges of the tear-off release layer 22, and the clamping grooves 23 can be provided with multiple clamping grooves 23 on at least one side of the tear-off release layer 22 in the width direction. The film applicator mainly includes a film bearing part 100. The film bearing part 100 can be a cover, and can also be directly used as the shell 400 of the film applicator. The film bearing part 100 is used as a cover in the embodiment, and the film bearing part 100 is a rectangle matched with the shape of the mobile phone 10. For the convenience of structural description, the middle line of the film bearing part 100 in the width direction is the width middle line, and the middle line of the length direction is the length middle line. The side surface of the film bearing part 100 used for installing the protective film 20 is the inner surface, and the protective film 20 is installed on the upper part of the film bearing part 100. The film bearing part 100 is provided with a film positioning sink 110 on the inner surface, and at least one side of the inner surface of the film bearing part 100 in the width direction is provided with multiple first plug-in sliding film fixing structures 200. The first plug-in sliding film fixing structure 200 includes a first limiting column 210 and a first film clamping boss 220. The first limiting column 210 is arranged on the inner surface of the film bearing part 100 and located outside the edge of the film positioning sink 110, and the first film clamping boss 220 is arranged on the first limiting column 210 and spaced from the inner surface of the film bearing part 100 to form a first film clamping groove 230. The clamping groove 23 on at least one side edge of the tear-off release layer 22 is sleeved into the first limiting column 210, so that the film layer 21 of the protective film 20 is located above the inner surface of the film bearing part 100, and the tear-off release layer 22 is located above the protective film 20. By pushing the protective film 20 to slide in the length direction, the clamping groove 23 at the edge of the tear-off release layer 22 is misaligned with the position of the first limiting column 210, so that the edge of the tear-off release layer 22 of the protective film 20 is clamped in the first film clamping groove 230, and the film layer 21 of the protective film 20 slides into the film positioning sink 110. The film positioning sink 110 is matched with the outer dimensions of the film layer 21 of the protective film 20, so that the film layer 21 is limited by the film positioning sink 110 after sliding into the film positioning sink 110.

[0043] As Figure 1 、 Figure 2 、 Figure 4As shown, the film applicator with the inserted sliding film fixing structure of the embodiment has a plurality of first inserted sliding film fixing structures 200 arranged on at least one side of the inner surface of the film bearing part 100 in the width direction, and when the protective film 20 is installed on the film bearing part 100, the edge of the tear-off release layer 22 of the protective film 20 is sleeved on the first limiting column 210 through the clamping groove 23 of the edge in the width direction, so that the protective film 20 can be directly placed on the inner surface of the film bearing part 100, and the protective film 20 is pushed in the length direction, so that the clamping groove 23 of the protective film 20 is offset from the position of the first limiting column 210, so that the edge of the protective film 20 is clamped in the first film clamping groove 230, and the film layer 21 of the protective film 20 is accommodated in the film positioning groove 110 by sliding to limit. Since the film layer 21 of the protective film 20 is limited in the film positioning groove 110 in the length direction and the width direction, and is limited by the first inserted sliding film fixing structure 200 in the up-down direction, the protective film 20 is stably installed on the film bearing part 100 and is not easy to loosen. Moreover, the form of the clamping groove 23 arranged on the protective film 20 is adopted, the offset clamping is realized by offsetting the position of the clamping groove 23 from the first limiting column 210, and the installation is completed, the pushing distance is short, and the installation is more convenient.

[0044] As shown in Figure 2 , Figure 3 Further, the first film clamping boss 220 of the embodiment protrudes on the inner side of the first limiting column 210, and the first film clamping boss 220 protrudes towards the width center line, so that the first film clamping groove 230 is located below the first film clamping boss 220. The side of the first film clamping boss 220 away from the inner surface of the film bearing part 100 is provided with an inclined guide surface 221. The inclined guide surface 221 is located on the upper surface of the first film clamping boss 220, and the inclined guide surface 221 gradually approaches the width center line in the direction from top to bottom. The form of the inclined downward is adopted, when the protective film 20 is installed, the edge of the clamping groove 23 of the protective film 20 abuts against the inclined guide surface 221, and is guided by the inclined guide surface 221, so that the clamping groove 23 can be smoothly sleeved on the outer side of the first limiting column 210 and slid downward, and the installation process of the protective film 20 is more convenient.

[0045] As shown in Figure 2 , Figure 3As shown, further, the first film clamping boss 220 of the embodiment is provided with an insertion inclined surface 222 at one end thereof in the sliding direction of the protective film 20. In the specific structure, the direction in which the clamping groove 23 is slid along the length direction to be misaligned with the position of the first limiting column 210 is the sliding direction, and the insertion inclined surface 222 is located at the sliding end of the lower surface of the first film clamping boss 220 in the length direction, and gradually approaches the inner surface of the film carrying portion 100 in the sliding direction. Thus, when the protective film 20 is installed, the edge of the clamping groove 23 on one side in the length direction of the protective film 20 abuts against the insertion inclined surface 222, and is guided by the insertion inclined surface 222, so that the clamping groove 23 can slide through the first film clamping groove 230, and the edge of the protective film 20 on the outside of the clamping groove 23 can smoothly slide into the first film clamping groove 230, so that the installation process of the protective film 20 is more convenient.

[0046] As shown in Figure 2 , Figure 3 As shown, further, the first film clamping boss 220 of the embodiment is provided with an insertion inclined surface 222 at one end thereof in the sliding direction of the protective film 20. In the specific structure, the direction in which the clamping groove 23 is slid along the length direction to be misaligned with the position of the first limiting column 210 is the sliding direction, and the insertion inclined surface 222 is located at the sliding end of the lower surface of the first film clamping boss 220 in the length direction, and gradually approaches the inner surface of the film carrying portion 100 in the sliding direction. Thus, when the protective film 20 is installed, the edge of the clamping groove 23 on one side in the length direction of the protective film 20 abuts against the insertion inclined surface 222, and is guided by the insertion inclined surface 222, so that the clamping groove 23 can slide through the first film clamping groove 230, and the edge of the protective film 20 on the outside of the clamping groove 23 can smoothly slide into the first film clamping groove 230, so that the installation process of the protective film 20 is more convenient.

[0047] As shown in Figure 2 , Figure 3 As shown, further, the first film clamping boss 220 of the embodiment is provided with an insertion inclined surface 222 at one end thereof in the sliding direction of the protective film 20. In the specific structure, the direction in which the clamping groove 23 is slid along the length direction to be misaligned with the position of the first limiting column 210 is the sliding direction, and the insertion inclined surface 222 is located at the sliding end of the lower surface of the first film clamping boss 220 in the length direction, and gradually approaches the inner surface of the film carrying portion 100 in the sliding direction. Thus, when the protective film 20 is installed, the edge of the clamping groove 23 on one side in the length direction of the protective film 20 abuts against the insertion inclined surface 222, and is guided by the insertion inclined surface 222, so that the clamping groove 23 can slide through the first film clamping groove 230, and the edge of the protective film 20 on the outside of the clamping groove 23 can smoothly slide into the first film clamping groove 230, so that the installation process of the protective film 20 is more convenient.

[0048] The inner surface of the film carrying portion 100 can be provided with the first insertion and sliding type film fixing structure 200 on both sides in the width direction, and the protective film 20 can be provided with the clamping groove 23 on both sides in the width direction, matched with the first insertion and sliding type film fixing structure 200 on both sides. Figure 1 Figure 2 Figure 4 ​​As shown, the first plug-in sliding film fixing structure 200 can be arranged on one side of the inner surface of the film carrying part 100 in the width direction, and the other side can be arranged with a plug-in groove structure. Thus, only one side of the protective film 20 needs to be provided with the clamping groove 23 in the width direction, and the other side can be in the form of a straight edge.

[0049] As shown in FIG. 1, the first plug-in sliding film fixing structure 200 is arranged on the inner surface of the film carrying part 100 in the width direction. Figure 1 、 Figure 2 、 Figure 4 As shown in FIG. 1, the first plug-in sliding film fixing structure 200 is arranged on the inner surface of the film carrying part 100 in the width direction. The second plug-in sliding film fixing structure 300 of the present embodiment includes a second limiting column 310 arranged on the inner surface of the film carrying part 100, and a second film clamping boss 320 arranged on the second limiting column 310 and spaced from the inner surface of the film carrying part 100 to form a second film clamping groove 330 in which the edge of the protective film 20 is clamped. The second film clamping boss 320 is provided with a guide inclined surface 321 on the side facing the inner surface of the film carrying part 100. The second plug-in sliding film fixing structure 300 is similar to the first plug-in sliding film fixing structure 200, but the edge of the tear-off release layer 22 cooperating with it does not need to be provided with a clamping groove 23, so it is not necessary to provide the second film clamping boss 320 with an insertion inclined surface 222 and an exit inclined surface 223, but it is necessary to provide the lower surface of the second film clamping boss 320 with a guide inclined surface 321, which is inclined from bottom to top in the direction gradually approaching the width center line. In this way, when installing the protective film 20, the edge of the tear-off release layer 22 of the protective film 20 is directly inserted obliquely into the plurality of second plug-in sliding film fixing structures 300, so that the long side of the tear-off release layer 22 is directly clamped into the second film clamping groove, without the need to push from the head end in the length direction, greatly saving the installation time.

[0050] As shown in FIG. 1, the first plug-in sliding film fixing structure 200 is arranged on one side of the inner surface of the film carrying part 100 in the width direction, and the other side can be arranged with a plug-in groove structure. Thus, only one side of the protective film 20 needs to be provided with the clamping groove 23 in the width direction, and the other side can be in the form of a straight edge. Figure 1 、 Figure 2 As shown in FIG. 1, the first plug-in sliding film fixing structure 200 is arranged on one side of the inner surface of the film carrying part 100 in the width direction, and the other side can be arranged with a plug-in groove structure. Thus, only one side of the protective film 20 needs to be provided with the clamping groove 23 in the width direction, and the other side can be in the form of a straight edge.

[0051] As shown in FIG. 1, the first plug-in sliding film fixing structure 200 is arranged on one side of the inner surface of the film carrying part 100 in the width direction, and the other side can be arranged with a plug-in groove structure. Thus, only one side of the protective film 20 needs to be provided with the clamping groove 23 in the width direction, and the other side can be in the form of a straight edge. Figure 1 、 Figure 2As shown, further, the film carrying part 100 of the embodiment has a press hole 140 passing therethrough. The press hole 140 is used to press the film layer 21 of the protective film 20 adhered to the mobile phone 10, so as to make the adhesion of the film layer 21 more firm.

[0052] As shown in Figure 1 , Figure 5 , Figure 6 As shown, further, the film applicator of the embodiment further comprises a housing 400 for accommodating and limiting the mobile phone 10 to be pasted with the film, and the film carrying part 100 is used to cover the housing 400. The housing 400 can be separately provided with the film carrying part 100, or can be hingedly connected in the length direction or the width direction. When the housing 400 limits the mobile phone 10, the film carrying part 100 serves as a cover to limit the protective film 20, and after the film carrying part 100 is connected with the housing 400 in position, the protective film 20 is accurately positioned with the mobile phone 10, so as to ensure the accuracy of the film pasting.

[0053] Embodiment Two

[0054] As shown in Figure 2 , Figure 5 , Figure 6 As shown, the film pasting kit of the embodiment comprises the film applicator with the plug-in sliding film fixing structure and the protective film 20 as described above. The protective film 20 of the embodiment specifically comprises a film layer 21 and a tear-off release layer 22. The film layer 21 can be a protective glass which can be accommodated and positioned in the film positioning groove 110 of the film carrying part 100, and is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10. The tear-off release layer 22 is arranged on the film layer 21 and protects the film layer 21, and the tear-off release layer 22 is used to cooperate with the first plug-in sliding film fixing structure 200 on the film carrying part 100, so as to connect the protective film 20 to the film carrying part 100. The tear-off release layer 22 is usually two layers, one layer is attached to the film layer 21, and the other layer extends out of the film carrying part 100, facilitating tearing.

[0055] When the film carrying part 100 is used in cooperation with the shell 400, the mobile phone 10 to be pasted with the film is placed in the shell 400, and the protective film 20 is installed on the film carrying part 100; then the film carrying part 100 is covered, so that the tear-off release layer 22 of the protective film 20 on the film carrying part 100 faces the screen of the mobile phone 10. The tear-off release layer 22 is pulled out from one end of the film carrying part 100 in the length direction, and then sequentially passes through the plurality of first film clamping grooves 230 and is separated from the protective film 20. At this time, the pasting film layer 21 does not move due to the blockage of the film positioning sink groove 110, so that the pasting film layer 21 remains in the film positioning sink groove 110 and faces the mobile phone 10. Then the pasting film layer 21 is pressed from the back pressing hole 140, so that the pasting film layer 21 is attached to the screen of the mobile phone 10, and the film pasting becomes simpler.

[0056] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
