[0039] Embodiment One

[0040] As Figure 3 , Figure 4As shown in the figure, the embodiment proposes a simple film applicator for applying a film to the screen of a mobile terminal. The mobile terminal in the embodiment can be a mobile phone 10, and can also be a tablet computer, an e-book, a smart watch, or the like. For the convenience of structural description of the embodiment, the length direction of the mobile phone 10 is taken as the length direction, the short side direction is taken as the width direction, and the thickness direction is taken as the up-down direction. The parts of the film applicator in the embodiment are described in the above directions. As shown in the figure, Figure 2 , Figure 3 As shown in the figure, the simple film applicator is used to bond a protective film 20 to the screen of the mobile phone 10. The protective film 20 can include a film layer 21 and a tear-off release layer 22. The film layer 21 is used to be attached to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10. The film layer 21 can be tempered glass. The tear-off release layer 22 is arranged on the film layer 21. In use, the tear-off release layer 22 is pulled away from the film layer 21, and only the film layer 21 is bonded to the screen surface of the mobile phone 10.

[0041] As shown in the figure, Figure 1 , Figure 2 The embodiment proposes a simple film applicator for connecting the protective film 20. As shown in the figure, Figure 3 The edge of the tear-off release layer 22 of the protective film 20 in the embodiment is provided with a clamping groove 23. Multiple clamping grooves 23 can be provided, and the multiple clamping grooves 23 are located on at least one side of the tear-off release layer 22 in the width direction. As shown in the figure, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the main part of the film applicator includes a cover 100 which is a rectangle matching the shape of the mobile phone 10. For the convenience of structural description, the middle line of the cover 100 in the width direction is the width middle line, and the middle line in the length direction is the length middle line. The side surface of the cover 100 on which the protective film 20 is installed is the upper surface, and the opposite side surface is the lower surface. The structure is described by taking the installation of the protective film 20 on the upper part of the cover 100 as an example. The film positioning groove 110 is arranged on the upper surface of the cover 100. The first plug-in sliding film fixing structure 200 is arranged on one side of the cover 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the cover 100 in the width direction. One or more first plug-in sliding film fixing structures 200 can be arranged on one side, and one or more second plug-in sliding film fixing structures 300 can be arranged on the other side. The side of the first plug-in sliding film fixing structure 200 away from the cover 100 and the side of the second plug-in sliding film fixing structure 300 away from the cover 100 are both provided with a clamping step 211. Therefore, the clamping steps 211 on both sides in the width direction form a terminal limiting part which is used for accommodating and limiting the mobile terminal to be pasted with the film. The side of the first plug-in sliding film fixing structure 200 towards the cover 100 and the side of the second plug-in sliding film fixing structure 300 towards the cover 100 form a film clamping groove 230. Specifically, the film clamping groove 230 is formed on the lower part of the first plug-in sliding film fixing structure 200 and the lower part of the second plug-in sliding film fixing structure 300, and the film clamping groove 230 on both sides in the width direction is used for clamping the two side edges of the tear-off release layer 22 of the protective film 20 in the width direction. When pasting the film, the side edge of the tear-off release layer 22 of the protective film 20 in the width direction is inserted into the film clamping groove 230 below the second plug-in sliding film fixing structure 300, and the other side edge of the tear-off release layer 22 of the protective film 20 is sleeved on the first plug-in sliding film fixing structure 200, so that the protective film 20 can be directly placed on the surface of the cover 100, and the protective film 20 is pushed in the length direction, so that the clamping groove 23 of the tear-off release layer 22 of the protective film 20 in the width direction is offset from the position of the first plug-in sliding film fixing structure 200, so that the edge of the tear-off release layer 22 of the protective film 20 is clamped below the film clamping groove 230 of the first plug-in sliding film fixing structure 200, and the pasting layer 21 of the protective film 20 is accommodated in the film positioning groove 110 for limiting; so as to realize the limiting of the cover 100 to the protective film 20.

[0042] As Figure 3 , Figure 4As shown, the simple film applicator of the embodiment is provided with the first and second slide-inserted film fixing structures 200 and 300 on both sides of the cover 100 in the width direction, so that the upper part of each of the first and second slide-inserted film fixing structures 200 and 300 is formed with a clamping step 211, and the lower part of each of the first and second slide-inserted film fixing structures 200 and 300 is formed with a film clamping groove 230. When the film is applied, the edge of the tear-off release layer 22 of the protective film 20 on one side in the width direction is inserted into the film clamping groove 230 below the second slide-inserted film fixing structure 300, the protective film 20 is pushed in the length direction, the clamping groove 23 on one side of the tear-off release layer 22 of the protective film 20 is misaligned with the position of the first slide-inserted film fixing structure 200, the edge of the tear-off release layer 22 of the protective film 20 is clamped in the film clamping groove 230, and the film layer 21 of the protective film 20 is accommodated in the film positioning groove 110 for limiting. Then, the mobile terminal to be applied with the film is placed on the clamping step 211 above, so that the mobile terminal is limited in the terminal limiting part, the screen of the mobile terminal faces and is opposite to the protective film 20 below. Thus, the protective film 20 and the mobile terminal to be applied with the film are both limited on the cover 100, the film application to the mobile terminal is completed by one cover 100 structure, the structure of the film applicator is simpler, the production cost is lower, and the use is more convenient.

[0043] As Figure 3 , Figure 5 , Figure 6As shown, further, the first plug-in slide film fixing structure 200 of the embodiment specifically comprises: a first limiting column 210 and a first film clamping boss 220. The first limiting column 210 is integrally formed on the upper surface of the cover body 100 and located outside the edge of the film positioning groove 110. The first film clamping boss 220 is protruded on the inner side of the first limiting column 210 along the width direction, so that the first film clamping boss 220 extends towards the inner side of the film positioning groove 110. In the specific structure, the first film clamping boss 220 is located in the middle of the upper and lower directions of the first limiting column 210, so that the side of the first film clamping boss 220 away from the cover body 100 and the first limiting column 210 form a clamping step 211, and the side of the first film clamping boss 220 towards the cover body 100 and the surface of the cover body 100 form a film clamping groove 230. Therefore, the clamping step 211 is located above the first film clamping boss 220, and the film clamping groove 230 is located below the first film clamping boss 220. In use, by tearing the tear-off layer 22 and making the clamping groove 23 on one side edge of the tear-off layer 22 fit into the first limiting column 210, the film layer 21 of the protective film 20 is placed on the upper surface of the cover body 100, and the tear-off layer 22 is located above the protective film 20; by pushing the protective film 20 to slide along the length direction, the clamping groove 23 on the edge of the tear-off layer 22 is misaligned with the position of the first limiting column 210, so that the edge of the tear-off layer 22 of the protective film 20 is clamped in the film clamping groove 230, and the film layer 21 of the protective film 20 slides into the film positioning groove 110. The film positioning groove 110 is matched with the film layer 21 of the protective film 20 in size, so that the film layer 21 is limited by the film positioning groove 110 after sliding into the film positioning groove 110. 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 plug-in slide film fixing structure 200 in the upper and lower directions, the protective film 20 is stably installed on the cover body 100 and is not easy to loosen. Moreover, the clamping groove 23 is formed on the protective film 20, and the clamping groove 23 is misaligned with the position of the first limiting column 210 to achieve clamping by pushing, so that the installation is completed only by misaligning the clamping groove 23 with the position of the first limiting column 210, the pushing distance is short, and the installation is more convenient.

[0044] As shown in Figure 3 , Figure 4 , Figure 6 As shown, the first limiting column 210 is located at the upper part of the first film clamping boss 220 as the vertical surface of the clamping step 211, and the upper surface of the first film clamping boss 220 is as the horizontal surface of the clamping step 211. When the mobile phone 10 is placed in the terminal limiting part, the clamping steps 211 on both sides of the width direction support and limit the left and right sides of the mobile phone 10 respectively, the vertical surfaces on both sides abut against the left and right sides of the mobile phone 10 respectively, and the horizontal surfaces on both sides support the left and right edges of the screen of the mobile phone 10 respectively, so as to achieve the support and limitation of the mobile phone 10.

[0045] As Figure 1 , Figure 3 , Figure 5 illustrated, further, the first film clamping boss 220 of the embodiment is provided with an inclined guide surface 221 on the side away from the upper surface of the cover body 100. The inclined guide surface 221 is located on the upper surface of the first film clamping boss 220, and gradually approaches the width center line in the direction from top to bottom. In the form of inclined downward, when the protective film 20 is installed, the edge of the clamping groove 23 of the protective film 20 abuts on the inclined guide surface 221, and is guided by the inclined guide surface 221, so that the clamping groove 23 is smoothly slid downward outside the first limiting column 210, and the installation process of the protective film 20 is more convenient.

[0046] As Figure 1 , Figure 3 , Figure 5 illustrated, further, the side of the first film clamping boss 220 of the embodiment towards the film slot 230, and located at one end of the sliding direction of the protective film 20 is provided with an insertion inclined surface 222. In the specific structure, the direction of sliding along the length direction to make the position of the clamping groove 23 and the first limiting column 210 staggered is the sliding direction, and then the insertion inclined surface 222 is located at the sliding end of the length direction of the lower surface of the first film clamping boss 220, and the insertion inclined surface 222 gradually approaches the upper surface of the cover body 100 in the sliding direction. In this way, when the protective film 20 is installed, the edge of the length direction of the clamping groove 23 of the protective film 20 abuts on the insertion inclined surface 222, and is guided by the insertion inclined surface 222, so that the clamping groove 23 slides through the film slot 230, and the edge of the protective film 20 outside the clamping groove 23 is smoothly slid into the film slot 230, and the installation process of the protective film 20 is more convenient.

[0047] As Figure 1 , Figure 3 , Figure 5 illustrated, further, the side of the first film clamping boss 220 of the embodiment towards the film slot 230, and located at one end of the sliding direction of the protective film 20 is provided with an insertion inclined surface 222. In the specific structure, the direction of sliding along the length direction to make the position of the clamping groove 23 and the first limiting column 210 staggered is the sliding direction, and then the insertion inclined surface 222 is located at the sliding end of the length direction of the lower surface of the first film clamping boss 220, and the insertion inclined surface 222 gradually approaches the upper surface of the cover body 100 in the sliding direction. In this way, when the protective film 20 is installed, the edge of the length direction of the clamping groove 23 of the protective film 20 abuts on the insertion inclined surface 222, and is guided by the insertion inclined surface 222, so that the clamping groove 23 slides through the film slot 230, and the edge of the protective film 20 outside the clamping groove 23 is smoothly slid into the film slot 230, and the installation process of the protective film 20 is more convenient.

[0048] It should be noted that the first and second plug-in sliding film fixing structures 200 and 300 on both sides of the upper surface of the cover body 100 in the width direction can be the same, and the corresponding protective film 20 is provided with a clamping groove 23 on both sides in the width direction to match the plug-in sliding film fixing structures on both sides.

[0049] As shown in FIGS. 1 and 2, the first plug-in sliding film fixing structure 200 is arranged on one side of the upper surface of the cover body 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the upper surface of the cover body 100 in the width direction. Figure 1 Figure 3 Figure 6 As shown in FIGS. 1 and 2, the first plug-in sliding film fixing structure 200 is arranged on one side of the upper surface of the cover body 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the upper surface of the cover body 100 in the width direction.The second plug-in sliding film fixing structure 300 of the embodiment specifically includes a second limiting column 310 and a second film clamping boss 320. The second limiting column 310 is arranged on the surface of the cover body 100, and the second film clamping boss 320 is arranged on the inner side of the second limiting column 310 in the width direction. The side of the second film clamping boss 320 away from the cover body 100 and the second limiting column 310 form a clamping step 211, and the second film clamping boss 320 and the surface of the cover body 100 form a film clamping groove 230. Therefore, the clamping step 211 is above the second film clamping boss 320, and the clamping step 211 above the second film clamping boss 320 is a mirror-symmetrical structure. The film clamping groove 230 is below the second film clamping boss 320, and the other side edge of the width direction of the tear-off release layer 22 of the protective film 20 is clamped in the film clamping groove 230. The side of the second film clamping boss 320 facing the upper surface of the cover body 100 is provided with a guide inclined surface 321. 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 matched with the second plug-in sliding film fixing structure 300 does not need to be provided with a clamping groove 23, so the second film clamping boss 320 does not need to be provided with an insertion inclined surface 222 and an exit inclined surface 223, but needs to be provided with a guide inclined surface 321 on the lower surface of the second film clamping boss 320. The guide inclined surface 321 is arranged from the lower surface to the upper surface in the direction of gradually approaching the width direction center line. In this way, when the protective film 20 is installed, the length direction edge of the tear-off release layer 22 of the protective film 20 is directly inserted 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 230, and the tear-off release layer 22 does not need to be pushed from the head end in the length direction, which greatly saves the installation time.​

[0050] As shown in Figure 1 , Figure 2 , Figure 3 Further, the cover 100 of the embodiment further comprises a stop portion 130 at one end in the length direction, the stop portion 130 is used for limiting the sliding of the protective film 20 in the length direction, and the stop portion 130 is also used for limiting the mobile phone 10 to be pasted in the length direction. The stop portion 130 specifically comprises two stop plates arranged at intervals, the stop plates are located outside the length direction of the film positioning groove 110, and the sliding of the protective film 20 in the length direction is limited, so that the installation of the protective film 20 is more convenient.

[0051] As shown in Figure 1 , Figure 2 Further, the cover 100 of the embodiment is provided with a pressing hole 140. The pressing hole 140 is used for pressing the pasting film layer 21 of the protective film 20 adhered on the mobile phone 10, so that the adhesion of the pasting film layer 21 is more firm. The pressing hole 140 can be a T-shaped hollow hole, a rectangular hollow hole and the like.

[0052] As shown in Figure 1 , Figure 2 Further, the cover 100 of the embodiment is provided with an inner recessed pull-out hole 120 at one end away from the stop portion 130 in the length direction. In the specific structure, the inner recessed pull-out hole 120 is formed by recessing the middle position of the bottom end edge of the cover 100 in the length direction towards the length center line, when the protective film 20 is installed on the cover 100, the lower end of the tear-off release layer 22 of the protective film 20 is exposed from the inner recessed pull-out hole 120, so as to facilitate the user to pinch the tear-off release layer 22 exposed in the inner recessed pull-out hole 120 with hands, and facilitate the tear-off release layer 22 to tear off the pasting film layer 21.

[0053] Embodiment two

[0054] As shown in Figure 2 , Figure 3 , Figure 6As shown, the protective film 20 in the present embodiment includes a film layer 21 and a tear-off release layer 22. The film layer 21 can be a protective glass that can be positioned in the film positioning groove 110 of the cover 100 and used to attach to the surface of the mobile phone 10 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 is used to cooperate with the first and second plug-in sliding film fixing structures 200 and 300 on the cover 100 to connect the protective film 20 to the cover 100. The tear-off release layer 22 is usually two layers, one of which is attached to the film layer 21 and the other of which extends to the outside of the cover 100 for easy tearing.

[0055] As shown, Figure 2 , Figure 3 , Figure 6 When the cover 100 is used to attach the film, the protective film 20 is installed in the lower film clamping groove 230, the mobile phone 10 to be attached with the film is placed in the upper clamping step 211, the screen of the mobile phone 10 faces downward, and the tear-off release layer 22 of the protective film 20 on the cover 100 faces the screen of the mobile phone 10.
