Description

Technical Field

[0001] The utility model relates to the technical field of film sticking devices, in particular to a film sticking device. Background Art

[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-applying devices include a base for placing electronic products and protective films and a rolling assembly arranged above the base. The rolling assembly includes a housing and a roller. The roller is rotatably connected to the housing, and the rolling assembly is slidably connected to the base (for specific structures, please refer to patents such as CN218489996U). When in use, the housing is slid to drive the roller to roll the protective film so that the protective film is attached to the screen to be applied.

[0004] In order to make it easier for the user to pull the shell, a finger hole is generally provided on the shell, and the user's finger is held in the finger hole, and then the shell is pulled to slide. However, during use, since the protective film is installed under the shell, the user's finger is easy to contact the protective film after passing through the finger hole, so the protective film is easily contaminated or damaged (scratched) during the film application operation, resulting in poor film application. Utility Model Content

[0005] The utility model aims to provide a film sticking device, which can prevent the user's fingers from contacting the protective film when pulling the shell, thereby avoiding the situation of pollution or damage of the protective film, and facilitates the user's finger to apply force.

It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0033] like Figures 1 to 7 As 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 a product to be pasted (not shown in the figure) (the product to be pasted can be a mobile phone, a tablet, etc.). A first positioning structure 17 is provided on the first positioning platform 13, and a second positioning structure 18 is provided on the second positioning platform 14. The first positioning structure 17 and the second positioning structure 18 are protrudingly provided on the first positioning platform 13 and the second positioning platform 14, respectively. The first positioning structure 17 and the second positioning structure 18 cooperate with each other to position the protective film (not shown) (specifically, one end of the protective film is hung on the first positioning structure 17, and the other end of the protective film is hung on the second positioning structure 18), thereby achieving positioning between the protective film and the product to be pasted.

[0034] The rolling assembly 2 is located above the base 1, and includes a housing 21 and a roller 22, and the roller 22 is rotatably connected to the housing 21. Slide rails 15 are provided on both side panels 12, and sliding parts 23 (the sliding parts 23 can be provided on the housing 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, and 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 housing 21 and the roller 22 can slide along the slide rails 15.

[0035] A hand latch groove 24 having a bottom wall 241 and a side wall 242 is provided on the outer surface of the shell 21 (i.e., the surface of the shell 21 away from the base 1, i.e., the upper surface of the shell 21). The hand latch groove 24 is formed by the outer surface of the shell 21 being recessed toward the side close to the base 1 (i.e., the hand latch groove 24 is formed by the outer surface of the shell 21 being recessed downward. The notch of the hand latch groove 24 is arranged opposite to its bottom wall 241 in upper and lower directions, and the notch of the hand latch groove 24 is located above its bottom wall 241).

[0036] The film pasting device provided by the utility model is provided with a base 1 and a rolling assembly 2. When in use, the product to be pasted with film is first placed in the positioning groove 10 for positioning, and then the protective film is placed above the product to be pasted with film, and the two ends of the protective film are respectively positioned by the first positioning structure 17 and the second positioning structure 18, so as to achieve the positioning between the product to be pasted with film and the protective film, and then the shell 21 is pulled to make the roller 22 move while rolling the protective film, so as to squeeze the protective film and adhere it to the product to be pasted with film. At the same time, by providing a hand-grip groove 24 on the outer surface of the shell 21, when in use, the user's fingers are placed in the hand-grip groove 24, and then the shell 21 is pulled to make the shell 21 slide, thereby completing the film sticking action; since the hand-grip groove 24 has a bottom wall 241 (it should be noted that the hole generally does not have a bottom wall, while the groove has a bottom wall), the user's fingers will contact the bottom wall 241 of the hand-grip groove 24 when in use, and will not pass through the bottom wall 241 of the hand-grip groove 24 and contact the protective film under the shell 21, thereby avoiding contamination or damage of the protective film, etc., and at the same time allowing the user to apply force to the shell 21 more confidently, facilitating the film sticking operation.

[0037] like Figures 2 to 8 As shown, as an embodiment, the bottom wall 241 and the side wall 242 of the hand buckle groove 24 both protrude downward from the inner surface of the shell 21 (i.e., the surface of the shell 21 close to the base 1, i.e., the lower surface of the shell 21), the bottom wall 241 of the hand buckle groove 24 is located on the side of the inner surface of the shell 21 close to the base 1, and the side wall 242 of the hand buckle groove 24 is connected between the bottom wall 241 of the hand buckle groove 24 and the inner surface of the shell 21. Since the thickness of the shell 21 is generally thin, the hand buckle groove 24 is extended to the lower side of the inner surface of the shell 21, so that the depth of the hand buckle groove 24 can be set deeper, so that the user's fingers can better buckle the hand buckle groove 24, which is convenient for applying force.

[0038] like Figure 8 As shown, as an implementation mode, the depth H1 (maximum depth) of the hand grip groove 24 is 5 mm to 15 mm, so that the user's fingers can better grip the hand grip groove 24 .

[0039] like Figure 2As shown, as an embodiment, the hand grip groove 24 is disposed on one end of the shell 21 close to the first positioning platform 13, so as to facilitate the user's finger force and help the shell 21 maintain stability when sliding.

[0040] like Figures 2 to 8 As shown, as an embodiment, a receiving hole 243 is provided on the side wall 242 (i.e., the rear side wall) of the hand-grip groove 24 close to the second positioning platform 14. The receiving hole 243 is used to accommodate the fingertips or finger pulps of the user's fingers (the user's fingertips can be buckled into the receiving hole 243), which can not only improve the hand feel, but also facilitate the user's finger to apply force.

[0041] like Figures 2 to 8 As shown, as an embodiment, the housing 21 is roughly square in structure, and the housing 21 has a length direction L and a width direction W that are perpendicular to each other. The hand-gripping groove 24 includes a plurality of finger-shaped grooves 240 (i.e., the shape of the finger-shaped grooves 240 is similar to the shape of the fingers), and the plurality of finger-shaped grooves 240 are arranged in sequence along the width direction W of the housing 21; when in use, each finger of the user can be placed in each finger-shaped groove 240. The side wall (i.e., the rear side wall) of each finger-shaped groove 240 close to the second positioning platform 14 is an arc-shaped (arc-shaped) structure. Such an arrangement can make the shape of the hand-gripping groove 24 similar to the shape of the finger, which can not only improve the hand feeling when the finger is buckled in the hand-gripping groove 24 (when the finger is buckled in the hand-gripping groove 24, the finger is in contact with the rear side wall of the finger-shaped groove 240, and the rear side wall of the finger-shaped groove 240 is an arc-shaped structure, which can fit well with the finger, thereby improving the touch), but also facilitate the user's finger to apply force.

[0042] As an implementation manner, the side wall of the finger-shaped groove 240 close to the second positioning platform 14 is an arc-shaped structure, and the curvature of the side wall of the finger-shaped groove 240 close to the second positioning platform 14 is 20-30 rad.

[0043] As an implementation, the number of finger-shaped grooves 240 is 2 to 4. Preferably, the number of finger-shaped grooves 240 is 3, and the 3 finger-shaped grooves 240 are respectively used for the user's index finger, middle finger and ring finger to be inserted, so as to facilitate the user to apply force. Of course, in other embodiments, the number of finger-shaped grooves 240 can also be 1.

[0044] like Figures 2 to 8 As shown, as an embodiment, each finger-shaped groove 240 is provided with a receiving hole 243 on the side wall close to the second positioning platform 14. The receiving hole 243 is used to accommodate the fingertip or finger pulp of the user, which can not only improve the hand feel, but also facilitate the user's finger to apply force.

[0045] like Fig.10 and Fig.11As shown in the figure, as another embodiment, a through hole 244 is provided on one side of the bottom wall of each finger-shaped groove 240 near the receiving hole 243, and the through hole 244 is connected with the receiving hole 243. By providing the through hole 244, the fingertip or the finger pulp of the user's finger can more easily enter the receiving hole 243, which can not only improve the hand feel, but also facilitate the user's finger to apply force.

[0046] like Figure 8 As shown, as an embodiment, the height H2 of the receiving hole 243 is less than or equal to the depth H1 of the buckle groove 24. The receiving hole 243 is generally a square structure, and the height H2 (maximum height) of the receiving hole 243 can be specifically 1mm to 10mm, and the width W1 of the receiving hole 243 (i.e., the maximum width along the width direction W) is 10mm to 30mm.

[0047] like Figures 5 to 8 As shown in FIG. 1 , as an embodiment, the plurality of finger-shaped grooves 240 are interconnected and connected as one. Fig. 9 As shown, as another embodiment, the plurality of finger-shaped grooves 240 are independently spaced apart from each other, that is, the plurality of finger-shaped grooves 240 are spaced apart along the width direction W, and the finger-shaped grooves 240 are not connected to each other.

[0048] like Figure 3 and Figure 4 As shown, as an embodiment, the roller 22 is arranged below the shell 21, and a rotating shaft 221 is provided at opposite ends of the roller 22. The rotating shafts 221 at opposite ends are respectively rotatably connected to opposite sides of the shell 21, so that the roller 22 can rotate relative to the shell 21.

[0049] like Figures 2 to 4 As shown, as an embodiment, the sliding part 23 is arranged on opposite sides of the housing 21; 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 21 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.

[0050] As an implementation method, the method for using the film sticking device is as follows:

[0051] When applying the film, first slide the roller 22 to the side of the first positioning structure 17 away from the positioning groove 10; then place the product to be applied with the film in the positioning groove 10 for positioning, and then place the protective film above the product to be applied with the film, and one end of the protective film is positioned by the first positioning structure 17, and the other end of the protective film is positioned by the second positioning structure 18, so as to achieve the positioning between the product to be applied with the film and the protective film. Then place the finger in the hand grip groove 24 and pull the shell 21 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 as to squeeze the protective film and attach it to the product to be applied with the film.

[0052] The film sticking device provided by the embodiment of the utility model provides a hand-grip groove 24 on the outer surface of the shell 21. When in use, the user's fingers are placed in the hand-grip groove 24, and then the shell 21 is pulled to slide, thereby completing the film sticking action; since the hand-grip groove 24 has a bottom wall 241, the user's fingers will contact the bottom wall 241 of the hand-grip groove 24 when in use, but will not pass through the bottom wall 241 of the hand-grip groove 24 and contact the protective film under the shell 21, thereby avoiding contamination or damage of the protective film, etc., and allowing the user to apply force to the shell 21 more assuredly, facilitating the film sticking operation.

[0053] 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. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
