Description

Technical Field

[0001] This utility model relates to the field of screen protector technology, and in particular discloses a simple screen protector application tool. Background Technology

[0002] Existing screen protector applicators present numerous inconveniences during use and transportation. Traditionally, the applicator and protective film are packaged separately and transported independently, which not only increases packaging costs and space occupation during transportation but also easily leads to wrinkles and dust accumulation on the protective film during transport, affecting the subsequent application effect. Furthermore, users must first remove the protective film from the packaging and then align it with the applicator, a cumbersome process. Improper alignment during this process can easily cause the protective film to shift, affecting application accuracy. This is especially problematic for non-professional users, making it difficult to complete the application quickly and accurately, thus failing to meet the demand for convenient and efficient screen protector application. Utility Model Content

[0003] In order to overcome the technical problems of cumbersome alignment steps of existing film applicators and protective films, and the fact that improper operation during the alignment process can easily cause the protective film to shift and affect the accuracy of film application, the purpose of this utility model is to provide a simple film application tool.

[0004] To achieve the above objectives, this utility model provides a simple screen protector applicator, comprising a limiting frame and a protective film disposed on the limiting frame. The protective film includes a film body and a release film attached to one side of the film body. The release film has a pull strip, and the protective film body is disposed on the limiting frame via the pull strip. The limiting frame has a first protrusion and a second protrusion. The limiting frame is used to fit over the outside of an external smart terminal. The first protrusion is used to abut against the screen frame of the external smart terminal. The protective film is located between the second protrusion and the screen of the smart terminal. The limiting frame has a pull-out opening. When the limiting frame is fitted over the outside of the external smart terminal, the release film is pulled away from the limiting frame by the pull strip, allowing the film body to adhere to the screen surface of the smart terminal.

[0005] Furthermore, the limiting frame is provided with a limiting post, the end of the pull strip away from the pull opening is provided with an adhesive ear, and the pull strip of the release film of the protective film and / or the adhesive ear of the pull strip are provided with positioning holes for accommodating the limiting post, and the release film is hung on the limiting post through the positioning holes.

[0006] Furthermore, when the limiting frame is fitted onto the outside of the smart terminal, the first protrusion forms an abutting surface and a clearance surface. The abutting surface is used to abut against the frame of the smart terminal, and the clearance surface is used for the release film pull strip and release film application pull-out. The distance between the clearance surface and the screen of the smart terminal is less than the thickness of the protective film body.

[0007] Furthermore, the contact surface is a plane of the first protrusion away from the second protrusion, and the avoidance surface is recessed from the first protrusion, forming a height difference between the avoidance surface and the contact surface.

[0008] Furthermore, the first protrusion has an avoidance notch on the side near the pull opening, and the release film pull strip protrudes out of the limiting frame through the avoidance notch.

[0009] Furthermore, the clearance notch extends through the limiting frame and / or the first protrusion in a direction parallel to the opening direction of the pull-out opening.

[0010] Furthermore, the limiting frame is provided with at least two arc-shaped grooves, which are located on opposite sides of the limiting frame. The arc-shaped grooves are used to fit the user's fingertips. When the limiting frame is fitted onto the outside of the smart terminal, the user presses the limiting frame with the arc-shaped grooves so that the second protrusion abuts against the protective film and tightly adheres the protective film to the screen of the smart terminal.

[0011] Furthermore, the limiting frame is also provided with a pressing plate, and the pressing plate is provided with the arc-shaped groove, through which the user can conveniently press the limiting frame.

[0012] Furthermore, the limiting frame is also provided with a buckle. When the screen frame of the external smart terminal abuts against the first protrusion, the buckle is used to stop the back cover and / or tail plug of the external smart terminal so that the smart terminal is stationary relative to the film body; that is, the smart terminal cannot move relative to the film body. If it moves relative to the film body, it will cause the gap between the screen of the smart terminal and the avoidance surface to change, affecting the stability of the film.

[0013] Furthermore, the fastener includes a first fastening part and a second fastening part. The first fastening part and the second fastening part are respectively located at opposite ends of the limiting frame, or the first fastening part and the second fastening part are located around the periphery of the limiting frame. The first fastening part extends from the limiting frame away from the first stop and bends or transitions into the limiting frame in an arc shape. The arc transition is used to match the arc structure of the back cover of the smart terminal and to fasten accordingly. The second fastening part extends from the limiting frame towards the first stop and has an arc segment. The second fastening part is used to insert the tail plug of the smart terminal and engage with it.

[0014] Furthermore, the simple screen protector also includes an elastic element, which is used to abut against the film body so that the external pressure flexibly abuts against the film body and moves it closer to the screen of the smart terminal to achieve air release; the elastic element extends along the length direction and / or width direction of the film body.

[0015] Furthermore, the limiting frame is provided with a protrusion that extends into the pull-out opening, and the extension direction of the protrusion is intersected with the opening direction of the pull-out opening.

[0016] Furthermore, the second buckle is disposed on the protrusion, and the second buckle is arranged crosswise relative to the protrusion. The second buckle is used to insert into the charging port (i.e., the tail plug) of the smart terminal, and the protrusion is used to block contact with the area around the charging port of the smart terminal.

[0017] Furthermore, the inner side of the limiting frame is provided with a clearance groove for avoiding the side buttons of the smart terminal.

[0018] Furthermore, the inner side of the limiting frame is provided with multiple ribs, which are arranged around the inner wall of the limiting frame and extend along the thickness direction of the limiting frame and in a direction parallel to the second stop.

[0019] The technical principle of this utility model is as follows: The limiting frame, as the main structure, can be directly fitted onto the outside of the external smart terminal. Positioning is achieved by the first protrusion contacting the screen frame of the smart terminal, ensuring the stability of the overall structure. The protective film is pre-set on the limiting frame via the release film's pull strip, realizing integrated transportation and installation of the film applicator and the protective film, avoiding the drawbacks of separate packaging. The release film of the protective film has a pull strip; after the limiting frame is fitted in place, the release film can be pulled away from the pull-out opening via the pull strip, allowing the film body to be gradually applied to the flat surface of the smart terminal under the action of the second protrusion. Simultaneously, the limiting posts on the limiting frame cooperate with the positioning holes of the pull strip, further ensuring the installation accuracy of the protective film. The elastic element assists in venting air during the film application process, preventing air bubbles from forming. The overall design simplifies the operation process and achieves precise and efficient film application.

[0020] The beneficial effects of this utility model are as follows: the protective film is directly set on the limiting frame through the release film strip, realizing the integrated transportation of the film applicator and the protective film, reducing packaging costs and transportation space, while avoiding damage or dust contamination of the protective film during transportation, and ensuring the quality of film application.

[0021] After the limiting frame is fitted onto the outside of the smart terminal, it achieves precise positioning through the first protrusion and the limiting post. Users only need to pull the release film strip to complete the film application, which greatly simplifies the operation steps, reduces the difficulty of use for non-professional users, and improves the efficiency of film application.

[0022] The first protrusion's avoidance notch and pull-out design facilitate the smooth removal of the release film, while the arc-shaped groove allows users to press the limiting frame, ensuring that the second protrusion tightly adheres the protective film to the screen. The fasteners enhance the connection stability between the limiting frame and the smart terminal.

[0023] The elastic element effectively assists in air venting and reduces air bubbles during film application, while the protrusions prevent the release film from shifting during removal. The overall solution meets users' needs for convenient, precise, and efficient film application, enhancing the user experience. Attached Figure Description

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0033] Please see Figures 1 to 6As shown, this utility model discloses a simple screen protector applicator, comprising a limiting frame 1 and a protective film 2 disposed on the limiting frame 1. The limiting frame 1 is an integrally molded structure, its shape adapted to the contour of the smart terminal 8, and preferably made of a lightweight plastic material. It is used to cover the smart terminal 8 from the front, forming a wrap-around fitting frame. The protective film 2 consists of two layers: a film body 22 and a release film 23. The film body 22 is located in the middle layer, and the release film 23 is disposed on the adhesive surface of the film body 22. Its tail end has a pull strip 231 structure, allowing the user to directly grasp and pull it out during operation. In actual use, a positioning film can also be added, which is attached to the side of the film body 22 away from the release film 23.

[0034] In this embodiment, the film body 22 is mounted on the limiting frame 1 via adhesive ears 2311 on the pull strip 231 of the release film 23. The adhesive ears 2311 and the limiting frame 1 are detachably mounted, achieving factory-preset assembly. During transportation, the film body 22 remains stably attached to the limiting frame 1, without falling off or shifting, ensuring the integrity of the structure before subsequent film application. The limiting frame 1 is provided with a first protrusion 3 and a second protrusion 4. The first protrusion 3 is used to abut against the screen frame of the smart terminal 8 when the limiting frame 1 is fitted into it, achieving automatic guidance and positioning. The second protrusion 4 is used to support the protective film 2, so that the film body 22 falls smoothly onto the screen surface of the smart terminal 8 during the process of pulling out the release film 23, avoiding film displacement due to gravity or air disturbance. The limiting frame 1 is also provided with a pull-out opening 10 structure, which is set in the direction of the pull strip 231 of the release film 23, so that the release film 23 can be smoothly pulled out along the pull direction under the action of the pull strip 231, so as to achieve unobstructed adhesion between the film body 22 and the screen surface.

[0035] Compared to existing technologies where the film application components and the film applicator are packaged separately and require manual splicing, positioning, and assembly, this structure simplifies the operation steps and improves the consistency and success rate of film application by pre-assembling the protective film 2 onto the limiting frame 1 to form an integrated package.

[0036] It should be noted that in actual use, the film applicator can also be packaged separately from the protective film 2. When using it, the limiting frame 1 can be first placed on the outside of the smart terminal 8, and then the positioning hole 211 on the adhesive ear 2311 of the release film 23 can be used to engage with the limiting post 11 on the limiting frame 1 to achieve the initial positioning of the film body 22.

[0037] Specifically, the front end of the limiting frame 1 is provided with two limiting posts 11, which are spaced apart on the indicator plate 13 of the frame. They are preferably cylindrical or conical in shape to ensure the hanging accuracy. The release film 23 has adhesive ears 2311 on the pull strip 231 with positioning holes 211. The number of positioning holes 211 is the same as that of the limiting posts 11, and the hole diameter is slightly larger than that of the limiting posts 11 to ensure smooth insertion during assembly.

[0038] When the screen protector is manufactured, the release film 23 of the protective film 2 is already attached to the limiting post 11 through these positioning holes 211, so that the film body 22 is stably attached to the middle of the limiting frame 1 and will not fall off or shift due to external force. Users do not need to disassemble or readjust; they only need to put the entire limiting frame 1 on the front of the phone to apply the screen protector.

[0039] Compared to the traditional structure where the protective film 2 is temporarily positioned by the positioning film, which is prone to loosening or misalignment, this structure achieves reliable positioning through the mechanical engagement of the limiting post 11 and the positioning hole 211, thereby improving the film alignment accuracy and structural assembly stability.

[0040] Preferably, the positioning hole 211 further includes an expansion opening, which is a blind hole or a through hole or break line penetrating the edge of the adhesive ear 2311. When the expansion opening is a through hole, the limiting post 11 is provided with an inclined portion, which extends in a direction away from the screen of the smart terminal 8 and in the direction in which the user pulls the pull bar 231. When the expansion opening is designed as a break line, that is, a dotted line structure is formed on the adhesive ear through a pre-cutting or indentation process, when the pull bar 231 is pulled out from the pull opening 10, the dotted line structure reduces the resistance of the adhesive ear 2311 to tearing away from the limiting post 11, thereby allowing the pull bar 231 to be quickly pulled out through the pull opening.

[0041] In addition, in the existing technology, a separate positioning film is required for positioning, and after removing the release film 23 and the pull strip 231 to attach the film body 22 to the screen of the smart terminal 8, the positioning film still needs to be peeled off separately. The operation steps are cumbersome and the manufacturing cost is increased. In contrast, this solution directly sets the corresponding positioning structure on the pull strip of the release film 23, which further saves the manufacturing cost of the protective film 2 and makes the operation more convenient.

[0042] In use, when the limiting frame 1 is fitted onto the smart terminal 8, the first protrusion 3 functions as a guide and limiter, forming two areas: a contact surface 31 and a clearance surface 32. The contact surface 31 is a straight structure of the first protrusion 3 facing the screen frame, used to directly abut against the frame of the smart terminal 8; the clearance surface 32 is a planar structure recessed from the end of the first protrusion 3 near the pull-out opening 10, forming a step difference between it and the contact surface 31, which facilitates the pull strip 231 and the release film 23 to naturally conform to the clearance area formed by the step difference without being squeezed or disturbed.

[0043] At this time, the distance between the clearance surface 32 and the screen of the smart terminal 8 is slightly less than the thickness of the protective film 2 body 22, so that the protective film 2 is in a pre-pressed state before being applied. This structural design ensures that the film body 22 can maintain a tight contact angle with the screen surface before being applied, and prevents the film body 22 from being pulled away from the pull-out opening 10 by the release film 23 at the end of the first protrusion 3 that abuts against the film body 22. The clearance surface 32 guides the release film 23 to not deviate when it is pulled out.

[0044] Preferably, the avoidance surface 32 is a planar structure. In actual use, the avoidance surface 32 can also be a wavy surface or a concave-convex surface. When the avoidance surface 32 is a wavy surface, the distance between the top of the wave crest of the wavy surface and the screen of the smart terminal 8 is less than the thickness of the film body 22 of the protective film 2. When the avoidance surface 32 is a concave-convex surface, the distance between the top of the convex surface of the concave-convex surface and the screen of the smart terminal 8 is less than the thickness of the film body 22 of the protective film 2.

[0045] Specifically, in actual use, the distance between the avoidance surface and the screen of the smart terminal can be equal to 0. At this time, the user needs to press down the limiting frame 1 with one hand and grasp the pull strip 231 with the other hand, so that the pulling force of the pull strip 231 is greater than the friction force applied by the limiting frame 1 to the release film 23 through the smart terminal 8. In actual operation, the pull strip 2321 and the release film 23 can be pulled out, and the pull strip 231 and the release film 23 will be deformed after being pulled out. Since the pull strip 231 and the release film 23 are not actually used, they do not affect the normal film application of the film body 22 of the release film 23. At the same time, since the above-mentioned distance is equal to 0, it can ensure that the film application of the film body 22 of the release film 23 is more stable and improve the air venting effect.

[0046] Specifically, in this embodiment, the limiting frame 1 is a frame structure surrounding the smart terminal 8. In actual use, the limiting frame 1 can be made into a semi-frame structure, that is, roughly "U" shaped, retaining only the pull-out opening 10, the first protrusion 3, the second protrusion 4, and the clearance notch 33. At this time, the protective film 2 and the limiting frame 1 are separate. In use, firstly, the limiting frame 1 is inserted into or slid into the smart terminal 8 from the tail, so that the first protrusion 3 abuts against the frame of the smart terminal 8 for limiting. Then, one end of the protective film 2 is inserted through the opening of the limiting frame 1 between the second protrusion 4 and the screen of the smart terminal 8, so that the pull strip 231 passes through the pull-out opening 10. The subsequent film application is the same as in the preferred embodiment, and will not be described in detail here.

[0047] Compared to the problem that the pull strip 231 of the release film 23 is easily bent or even torn in the ordinary planar frame structure, this structure optimizes the channel and alignment of the pull strip 231 by forming a height difference between the contact surface 31 and the avoidance surface 32, which enhances the stability of the film and makes the film body 22 stable and does not shift during the pulling process.

[0048] Specifically, on the side near the pull-out opening 10, the first protrusion 3 is provided with a clearance notch 33. This notch is a recessed channel opened on the side of the frame, allowing the release film 23 pull strip 231 to naturally protrude from this position for the user to grasp. The clearance notch 33 is arranged parallel to the opening direction of the pull-out opening 10, so that when applying the film, the user can naturally place their fingers on the side of the limiting frame 1 and smoothly pull out the release film 23 through the pull strip 231 without affecting the alignment position of the film body 22.

[0049] The pull strip 231 can be made of transparent PET material. The surface of the pull strip 231 has a micro-textured surface to enhance friction and facilitate user operation. During the pulling process, the release film 23 bends and adheres to the screen of the smart terminal 8, carrying away any dust that may be present on the screen. When the release film 23 is completely removed from the limiting frame 1, a gap is formed between the film body 22 and the screen. At this point, the film body 22 can be pressed to allow the adhesive surface of the film body 22 to gradually adhere to the screen using van der Waals forces.

[0050] Compared to the problem of inconvenient operation caused by the lack of a dedicated pull strip 231 outlet in the structure, this structure improves ease of use and consistency of film application by setting an avoidance notch 33 to clarify the path of the pull strip 231.

[0051] Specifically, two arc-shaped grooves 12 are respectively provided on both sides of the limiting frame 1. These arc-shaped grooves 12 are set along the length of the frame and have a depth of about 1 / 3 to 1 / 2 of the frame thickness, designed to fit the shape of the user's fingertips. The user can insert their thumb, index finger, etc., into the arc-shaped grooves 12 and press the arc-shaped grooves 12 to achieve stable support for the frame, thereby controlling the second protrusion 4 to press the film body 22 onto the screen, achieving precise and even film application. An integrally formed pressing plate 16 can also be provided on the frame. The surface of the pressing plate 16 has a first arc-shaped groove 12 to enhance the finger fit and improve the pressing feel.

[0052] Specifically, compared to the problem of slippage during film application caused by the lack of a clear gripping position in traditional frames, this structure enhances user operation stability and film application precision by setting an ergonomic arc groove 12 and a pressing plate 16.

[0053] Specifically, the pressing plate 16 is provided with an elastic element 6 on the side near the release film 23, and the elastic element 6 extends along the width direction of the film body 22. When the user applies external force through the pressing plate 16 on the limiting frame 1, the elastic element 6 can flexibly press the film body 22 against the screen surface from top to bottom, so that the adhesive surface of the film body 22 gradually adheres to the screen surface by means of van der Waals forces, thereby improving the uniformity of adhesion and the screen adhesion rate.

[0054] Preferably, the elastic element 6 includes a pressing plate 16 integrally formed on the first pressing plate 16, and a cuboid sponge strip detachably disposed on the pressing plate 16. If the sponge strip becomes insufficient in its elasticity after repeated use, a new sponge strip can be replaced.

[0055] In actual use, the elastic element 6 can also be designed as a silicone strip and glued to the first pressing plate 16.

[0056] Specifically, the outer wall of the limiting frame 1 is also provided with a buckle 5, including a first buckle 51 and a second buckle 52, which are located at opposite ends or around the frame. The first buckle 51 adopts an arc transition structure, which can be bent inward and fit the rounded corner shape of the back cover of the mobile phone. The second buckle 52 extends toward the tail plug position of the smart terminal 8 and has a groove section or a latch section structure for locking with the tail plug interface.

[0057] The buckle 5 automatically abuts and locks in place when the frame is fitted, effectively preventing the limiting frame 1 from loosening or slipping during operation and improving the overall structural stability. The inner side of the limiting frame 1 is also provided with an avoidance groove 15 and a reinforcing rib 14. The avoidance groove 15 is used to avoid the side buttons and volume buttons of the mobile phone, and the rib 14 strengthens the overall longitudinal structural stability of the frame and prevents deformation during pressing or pulling.

[0058] Compared to traditional structures that rely solely on friction-locking for positioning, this structure achieves a more secure installation through a double-clamping mechanism, thereby improving the overall lifespan and stability of the applicator.

[0059] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
