[0002] Electronic products with screens, such as mobile phones and computers, currently available on the market generally require a layer of protective film to be attached to the surface of the screen to protect the screen. Since the screen is often touched, the protective film will be damaged after a period of use, so the protective film needs to be replaced frequently. The roller-type film-applying device is a new type of film-applying device, which positions the screen to be filmed and the protective film by setting a positioning structure, and sets a roller to roll the protective film, so that the protective film can be attached to the screen to be filmed from one end to the other end in sequence, so that the protective film can be accurately and efficiently attached to the product to be filmed, and prevents the generation of bubbles during the film-applying process.

[0003] At present, some roller-type film-sticking devices include a base for placing electronic products and protective films and a rolling assembly arranged above the base. The rolling assembly includes a base and a roller. The roller is rotatably connected to the base, and the rolling assembly is slidably connected to the base (the specific structure can refer to the patent announcement number CN218489996U and other patents). When in use, by pulling (or pushing) the base to slide relative to the base, the roller is driven to roll the protective film so that the protective film is attached to the screen to be filmed. Because when pulling the base, it is necessary to keep the base stationary (of course, the base can also be stationary and the base can slide, as long as the base and the base can slide relative to each other), and the base of the current film-sticking device is not provided with a gripper for the user to fix the base by hand, which makes the film-sticking operation inconvenient.

[0036] like Figures 1 to 8As shown, the film pasting device provided by the embodiment of the utility model includes a base 1 and a rolling assembly 2. The base 1 includes a bottom plate 11, two side plates 12 respectively arranged on opposite sides of the bottom plate 11, and a first positioning platform 13 and a second positioning platform 14 respectively arranged on opposite ends of the bottom plate 11. The first positioning platform 13 and the second positioning platform 14 are both located between the two side plates 12. The bottom plate 11, the side plate 12, the first positioning platform 13 and the second positioning platform 14 are an integrated structure. The bottom plate 11, the two side plates 12, the first positioning platform 13 and the second positioning platform 14 enclose a positioning groove 10 for placing the product to be pasted (the product to be pasted can be a mobile phone, a tablet, etc.). A first positioning structure 16 is provided on the first positioning platform 13, and a second positioning structure 17 is provided on the second positioning platform 14. The first positioning structure 16 and the second positioning structure 17 are protrudingly provided on the first positioning platform 13 and the second positioning platform 14, respectively. The first positioning structure 16 and the second positioning structure 17 cooperate to position the protective film (not shown) (specifically, one end of the protective film is hung on the first positioning structure 16, and the other end of the protective film is hung on the second positioning structure 17), so as to achieve positioning between the protective film and the product to be filmed. A buckle 3 is provided on one side of the first positioning platform 13 away from the positioning groove 10, and the buckle 3 is connected to the base 1.

[0037] The rolling assembly 2 is located above the base 1, and includes a base 21 and a roller 22, and the roller 22 is rotatably connected to the base 21. Slide rails 15 are provided on both side panels 12, and sliding parts 23 (the sliding parts 23 can be provided on the base 21 and / or the roller 22) that match the slide rails 15 are provided on opposite sides of the rolling assembly 2, and the roller 22 is provided corresponding to the sliding parts 23. The sliding parts 23 on opposite sides of the rolling assembly 2 are respectively slidably connected to the slide rails 15 on the two side panels 12, so that the base 21 and the roller 22 can slide along the slide rails 15.

[0038] The film pasting device provided by the utility model is provided with a buckle piece 3 on the side of the first positioning platform 13 away from the positioning groove 10, and the buckle piece 3 is connected to the base 1. When pasting the film, the film pasting device is placed on the table, and the user buckles the buckle piece 3 with one hand to fix the base 1, and the user pulls the base 21 with the other hand to make the base 21 slide relative to the base 1, thereby driving the roller 22 to roll the protective film, so that the protective film is attached to the screen to be pasted, and then the film pasting action is completed. The film pasting device is provided with a buckle piece 3, and the buckle piece 3 serves as the buckle position of the base 1, so that the user can fix the base 1 by pulling the buckle piece 3 when pasting the film, thereby facilitating the film pasting operation.

[0039] like Figures 1 to 5As shown, as an embodiment, the base 21 is a shell 211, the shell 211 can cover the base 1, and the roller 22 is rotatably connected to the shell 211; the roller 22 is arranged below the shell 211, and the opposite ends of the roller 22 are provided with a rotating shaft 221, and the rotating shafts 221 at the opposite ends are respectively rotatably connected to the opposite sides of the shell 211, so that the roller 22 can rotate relative to the shell 211. When the sliding part 23 slides to the end of the slide rail 15 close to the first positioning platform 13, the shell 211 can rotate relative to the base 1 (such as Figure 7 and Figure 8 As shown, the housing 211 rotates relative to the base 1 to an open state), so that the housing 211 can be rotated and uncovered before placing the protective film, so as to facilitate placing the product to be filmed in the positioning groove 10 and placing the protective film on the product to be filmed (that is, after the housing 211 is rotated, the positioning groove 10 and the positioning structure 16 / 17 on the base 1 are exposed). Specifically, in this embodiment, the slide rail 15 includes a steering rail 151, which is arranged corresponding to the first positioning platform 13, and the steering rail 151 is extended downward. When the sliding part 23 slides onto the steering rail 151, the sliding part 23 can slide downward along the steering rail 151. At this time, the sliding part 23 can rotate relative to the base 1 at the steering rail 151, that is, the housing 211 can rotate relative to the base 1.

[0040] like Figures 1 to 5 As shown, as an embodiment, the sliding part 23 is arranged on opposite sides of the housing 211; the slide rail 15 is an outer rail, and the slide rail 15 is arranged at the top side of the side plate 12, and the slide rail 15 protrudes outward compared to the side plate 12; that is, the housing 211 is directly slidably connected to the base 1. Of course, in other embodiments, the slide rail 15 and the sliding part 23 can also be other structural forms, for example, the slide rail 15 is a slide groove (not shown) arranged on the inner wall of the side plate 12, and the sliding part 23 is a rotating shaft 221 at both ends of the roller 22, and the rotating shaft 221 is located in the slide groove and can slide along the slide groove, that is, the roller 22 is directly slidably connected to the base 1.

[0041] Of course, in other embodiments, the base 21 may also be in other structural forms. Fig.11 As shown, the base 21 includes a sliding seat 212 and a handle 213, the roller 22 is rotatably connected to the sliding seat 212, and the sliding parts 23 are arranged on opposite sides of the sliding seat 212, that is, the sliding seat 212 is directly slidably connected to the base 1; the handle 213 is rotatably connected to the sliding seat 212, and the user pulls the handle 213 to drive the sliding seat 212 and the roller 22 to move. For another example, Fig.12As shown, the base 21 includes a sliding seat 212 and a cover shell 214, the cover shell 214 can cover the base 1, the roller 22 is rotatably connected to the sliding seat 212, and the sliding part 23 is arranged on opposite sides of the sliding seat 212, that is, the sliding seat 212 is directly slidably connected to the base 1; the cover shell 214 is rotatably connected to the sliding seat 212, and the user pulls the cover shell 214 to drive the sliding seat 212 and the roller 22 to move.

[0042] like Figure 7 and Figure 8 As shown, as an embodiment, when the sliding part 23 slides to the end of the slide rail 15 close to the first positioning platform 13, the shell 211 can rotate relative to the base 1, so the film sticking device can be used as a bracket (mobile phone bracket or other electronic product bracket). When the film sticking device acts as a bracket, the shell 211 rotates and opens relative to the base 1, and one end of the electronic product 4 (such as a mobile phone) abuts against the shell 211, and the other end abuts against the base 1, thereby supporting the electronic product 4. Figure 2 and Figure 7 As shown, the housing 211 is provided with a limiting groove 211B. When the electronic product 4 is placed horizontally, one end of the electronic product 4 can be stuck in the limiting groove 211B, and the other end of the electronic product 4 can be against the second positioning structure 17 on the base 1. Or, as Figure 3 and Figure 8 As shown, a stopper 112 is provided on the inner wall of the base 1 (specifically, the bottom plate 11). When the electronic product 4 is placed in the longitudinal direction, one end of the electronic product 4 abuts against the housing 211, and the other end of the electronic product 4 abuts against the stopper 112. Of course, the electronic product 4 and the film sticking device can also be in other abutment forms; the placement position and standing angle of the electronic product 4 are different when the housing 211 is rotated and opened at different angles.

[0043] like Figures 1 to 6 As shown in FIG. 1 , as an embodiment, the handle 3 is rotatably connected to the base 1, and the handle 3 has an unfolded state and a folded state. Figure 1 As shown, when the buckle member 3 is in the unfolded state, the buckle member 3 extends to the side of the first positioning platform 13 away from the positioning groove 10; Figure 6 As shown, when the buckle member 3 is in the folded state, the buckle member 3 can be in contact with the housing 211. At the same time, a snap-fitting portion 211A is provided on one end of the housing 211 close to the buckle member 3, and the buckle member 3 can snap-fit ​​with the snap-fitting portion 211A on the housing 211 to lock the housing 211 in the current position; that is, the buckle member 3 can be used as a lock. In this embodiment, the snap-fitting portion 211A is a snap-fitting hole, and the buckle member 3 is provided with a protrusion 36 that can snap-fit ​​with the snap-fitting hole; of course, the snap-fitting portion 211A can also be a structure such as a snap-fitting groove.

[0044] Specifically, since the buckle handle 3 is rotatably connected to the base 1, when performing the film application operation, the buckle handle 3 is rotated to the position as shown in FIG. Figure 1 The unfolded state shown in FIG. 1 allows the user to hold the buckle member 3 by hand to facilitate the film application operation. When performing operations such as packaging, transportation, and storage, the buckle member 3 is rotated to the position shown in FIG. Figure 6 In the folded state shown in the figure, the buckle member 3 is in contact with the shell 211 and is engaged with the engaging portion 211A on the shell 211 to lock the shell 211. On the one hand, it can save the space occupied by the buckle member 3, and on the other hand, it can lock and fix the shell 211 to prevent the shell 211 from sliding relative to the base 1 during transportation. Figure 7 As shown, when the film sticking device acts as a bracket, after the shell 211 is rotated to an open state relative to the base 1, the buckle member 3 can engage with the locking portion 211A on the shell 211 to lock the shell 211 and keep the shell 211 at the current angle.

[0045] like Figure 2 , Figure 3 and Figures 9a to 9c As shown, as an embodiment, a first limiting surface 30A, a second limiting surface 30B and a third limiting surface 30C are sequentially provided on the side wall of the buckle member 3 close to the first positioning platform 13, and the first limiting surface 30A, the second limiting surface 30B and the third limiting surface 30C are all planar structures, and the angle between the first limiting surface 30A and the second limiting surface 30B is an obtuse angle, and the angle between the second limiting surface 30B and the third limiting surface 30C is an obtuse angle;

[0046] like Figure 6 and Fig.9c As shown, when the buckle member 3 is in the folded state, the first limiting surface 30A abuts against the outer side wall of the base 1 (ie, the side wall away from the positioning groove 10); Figure 1 and Figure 9a As shown, when the buckle member 3 is in the unfolded state, the third limiting surface 30C abuts against the outer wall of the base 1; Figure 7 and Figure 9b As shown, when the shell 211 is rotated to the open state, and the buckle member 3 is engaged with the engaging portion 211A on the shell 211, the second limit surface 30B abuts against the outer wall of the base 1. Since the surface of the buckle member 3 is in contact with the surface of the base 1 (i.e., surface-to-surface contact) when the buckle member 3 is in each state, the buckle member 3 can remain in the current state without rotating by itself. In other words, when the state of the buckle member 3 needs to be switched, a certain force needs to be applied to rotate the buckle member 3.

[0047] like Figure 3 and Figure 9aAs shown, as an embodiment, when the handle 3 is in the unfolded state, the lowermost end of the handle 3 is located below the lower surface of the base 1 (bottom plate 11), so that the end of the base 1 close to the first positioning platform 13 can be supported by the handle 3. Specifically, a camera hole 111 is provided on the bottom plate 11. When applying the film, the base 1 is placed on a table (such as a desktop). When the product to be applied with the film (such as a mobile phone) is placed in the positioning groove 10 on the base 1, the camera of the product to be applied with the film is exposed downward through the camera hole 111. At this time, since the end of the base 1 close to the first positioning platform 13 is supported by the handle 3, that is, the lower surface of the end of the base 1 close to the first positioning platform 13 will not contact the table, thereby avoiding the problem of scratches and damage to the camera caused by contact with the table.

[0048] like Figure 3 and Figure 9a As shown, as an embodiment, a support portion 33 is provided on the handle 3 near the connection position between the handle 3 and the base 1; when the handle 3 is in the unfolded state, the end of the handle 3 close to the first positioning platform 13 is supported by the support portion 33 (that is, the support portion 33 is equivalent to the support foot of the handle 3), thereby further preventing the handle 3 from rotating by itself when the film is applied.

[0049] like Figure 3 and Figure 9a As shown, as an embodiment, the buckle member 3 includes an extension portion 31 and a buckle portion 32, one end of the extension portion 31 is connected to the base 1, the buckle portion 32 is arranged at the end of the extension portion 31 away from the base 1, the protrusion 36 is arranged on the buckle portion 32, and the buckle portion 32 is connected to the extension portion 31 to form an L-shaped structure. When in use, the user can buckle the buckle portion 32 with his hand.

[0050] like Figure 2 and Figure 3 As shown, as an embodiment, the buckle member 3 is connected to the side of the first positioning platform 13 away from the positioning groove 10. The length of the buckle member 3 is less than the spacing between the two side plates 12, and the opposite ends of the buckle member 3 are respectively spaced from the two side plates 12 (that is, the opposite ends of the buckle member 3 are respectively spaced from the two side plates 12 by a certain distance), so as to avoid interference between the buckle member 3 and the shell 211 when the shell 211 rotates.

[0051] Specifically, rotating shafts 35 are provided on opposite sides of the extension portion 31 close to one end of the base 1, and rotating holes 131 are provided on opposite sides of the first positioning platform 13. The rotating shafts 35 on opposite sides are respectively located in the rotating holes 131 on opposite sides to realize the rotating connection between the buckle 3 and the first positioning platform 13.

[0052] like Fig.10As shown, as another embodiment, the buckle member 3 and the base 1 can also be fixedly connected, and the buckle member 3 and the base 1 can be an integral structure, and the buckle member 3 extends outward from the base 1 toward the side away from the positioning groove 10.

[0053] like Figures 1 to 3 As shown, as an embodiment, a hook hole 34 is provided on the buckle piece 3, and the buckle piece 3 can also be used as a hook; when the film sticking device is being stored or displayed, the buckle piece 3 can be hung at a designated position to improve the convenience of use.

[0054] like Figure 1 and Figure 2 As shown, as an implementation mode, a hand-grip groove 210 is provided on the shell 211 , and the hand-grip groove 210 is used for the user to pull the shell 211 by hand.

[0055] As an implementation method, the method for using the film sticking device is as follows:

[0056] When applying the film, place the film applying device on the table, first rotate the buckle 3 to the unfolded state, slide the roller 22 to the side of the first positioning structure 16 away from the positioning groove 10, and rotate to open the shell 211; then place the product to be applied with the film in the positioning groove 10 for positioning, and then place the protective film on the product to be applied with one end of the protective film positioned by the first positioning structure 16, and the other end of the protective film positioned by the second positioning structure 17, so as to achieve the positioning between the product to be applied with the film and the protective film. Then rotate the shell 211 in the opposite direction to close the shell 211 (i.e., Figure 1 In the state shown in the figure, the user holds the hand buckle 3 with one hand to keep the base 1 fixed, and the user places the other hand in the hand buckle groove 210 and pulls the shell 211 to move the rolling assembly 2 toward the side close to the second positioning platform 14. At this time, the roller 22 moves while rolling the protective film, so that the protective film is squeezed and attached to the product to be filmed.

[0057] The film pasting device provided by the embodiment of the utility model is provided with a buckle piece 3 on the side of the first positioning platform 13 away from the positioning groove 10, and the buckle piece 3 is connected to the base 1. When pasting the film, the film pasting device is placed on the table, and the user holds the buckle piece 3 with one hand to fix the base 1, and the user pulls the base 21 with the other hand to make the base 21 slide relative to the base 1, thereby driving the roller 22 to roll the protective film, so that the protective film is attached to the screen to be pasted, and then the film pasting action is completed. The film pasting device is provided with a buckle piece 3, and the buckle piece 3 serves as the buckle position of the base 1, so that the user can fix the base 1 by pulling the buckle piece 3 when pasting the film, thereby facilitating the film pasting operation.

[0058] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
