Abstract
Description
Technical Field
[0001] This utility model relates to the field of film applicator technology, and in particular to a film applicator cover and a film applicator. Background Technology
[0002] In today's electronic device market, screen protectors are an indispensable part, effectively protecting the displays of devices such as mobile phones and tablets from scratches and other physical damage. With the increasing popularity of smartphones and tablets, and the continuous improvement in screen size and resolution, users have higher and higher demands for screen protector quality. However, in practice, both professionals and ordinary consumers often encounter various problems when applying these screen protectors. These problems not only affect the final visual effect but may also reduce the actual protective performance of the screen protector.
[0003] While the tools and technologies available on the market have improved, some significant problems still exist:
[0004] Difficulty in securing the positioning film: Existing applicator cap designs often lack an effective mechanism to firmly hold the positioning film in place. This can cause the positioning film to shift during application, affecting the accuracy of the entire application process.
[0005] The positioning film and protective film cannot be separated when opening the lid: A major drawback of traditional film application tools is that the positioning film and protective film cannot be separated smoothly when opening the lid, and the positioning film needs to be manually peeled off.
[0006] The lack of height difference design limits unidirectional air venting: Most existing screen protector covers do not take into account the height difference between the front and rear hooks when fixing the film assembly. This prevents air from being effectively vented from a single direction during the application process, making it easy for air bubbles to form under the protective film. This design flaw seriously affects the quality of the screen protector application, especially on high-precision screens, where even tiny air bubbles can negatively impact the user experience.
[0007] Lack of pre-pressure function: Some screen protector application tools fail to provide sufficient pre-pressure to ensure that the back end of the screen protector makes smooth contact with the screen first. This may result in wrinkles or incomplete edge adhesion or inaccurate positioning during the application process, further reducing the success rate and aesthetics of the application.
[0008] Inconvenient to operate: Traditional screen protector application tools may have neglected the actual user experience in their design. For example, improper control of the release film's movement direction may result in an unsmooth operation when removing the release film; or the opening action after applying the screen protector may be too cumbersome, affecting overall efficiency.
[0009] In view of the above problems, there is an urgent need for a new type of film applicator and its cap that can solve the various shortcomings of the existing technology and provide users with an efficient, accurate and easy-to-use film application solution. Utility Model Content
[0010] This utility model aims to comprehensively improve the user experience and film application quality during the film application process through a series of innovative design improvements.
[0011] This utility model provides a screen protector cover, including a cover body. The inner side of the cover body is provided with a front hook and a rear hook for fixing the positioning film, located at the front and rear ends of the cover body respectively. A pivot for rotatable connection with a base is provided at the rear end of the cover body. The front hook is shorter than the rear hook; this design allows the protective film at the rear end to adhere to the screen first during application, achieving one-way air venting and reducing air bubbles. The end of the front hook has a long, angled hook extending towards the front end of the cover body. This design effectively solves the problem of the positioning film being pulled away from the protective film by the front hook when the cover is opened after application; it achieves the effect of applying the film with the cover closed and separating the positioning film from the protective film upon opening, completing the application in a simple opening and closing motion. Furthermore, due to the height difference between the front and rear hooks, the positioning film and protective film automatically separate at the front end.
[0012] Further description of the aforementioned solution: the hook of the rear hook extends toward the rear end of the cover body, and the hook length is 0.5mm-2mm. The hook itself has a certain elasticity. When installing the positioning film, first, the front end of the positioning film is inserted into the front hook, and then a little force is applied to fix the rear end of the positioning film to the rear hook.
[0013] Furthermore, the length of the long oblique hook is 2mm-5mm, which effectively pulls the positioning film when the cover is opened, thus separating the positioning film from the protective film.
[0014] Even better, a central hook is provided in the middle of the lid body, which is used to fix the middle of the positioning film.
[0015] Optionally, two pressure strips for pre-pressing the protective film are also provided on the inner rear end of the cover body, so that when applying the film, the rear end of the protective film is first attached and positioned to the screen.
[0016] Even better, the inner front end of the lid body is provided with two limiting hooks for locking the release film. The direction of the limiting hooks is the same as that of the front hook, so that the release film can only move in one direction, ensuring that the handle of the release film will not retract into the lid body.
[0017] Optionally, a through hole is provided in the center of the cover body to facilitate observation of the film application or pressing of the protective film.
[0018] This utility model also provides a screen protector applicator, including a front screen protector cover body and a base. The cover body is connected to the rear end of the base via pivots on both sides of the rear end. The base is provided with a positioning device for positioning the mobile phone. The positioning device can be a detachable positioning block or a positioning frame that is injection molded with the base.
[0019] Even better, the base has positioning posts at both ends to secure the positioning film. This design allows the cover body to be removed, and the positioning film can be directly fixed to the base to accommodate other types of film assemblies. The base has lens clearance holes to avoid obstructing the phone camera, and a reinforcing strip is also provided in the center of the base.
[0020] Furthermore, the front sides of the lid body are provided with locking blocks, and the side shell walls of the base are provided with matching locking grooves. When the lid body is closed on the base, the locking blocks are locked in the locking grooves, so that the lid body is fixed to the base, and the upper surface of the lid body coincides with the upper surface of the base, thus realizing the function of the packaging box.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] One-way venting mechanism: Through a carefully designed height difference between the front and rear hooks (the front hook is shorter than the rear hook), the rear end of the protective film contacts the screen first, thus achieving the effect of venting air from a single direction. This design greatly reduces the chance of air bubbles forming during the application process, ensuring the quality and smoothness of the film application.
[0023] The positioning film and protective film automatically separate: Due to the height difference between the front hook and the rear hook, the positioning film and protective film automatically separate at the front end when the film is applied.
[0024] Optimized rear hook design: The rear hook extends towards the rear end of the cover body and has an elastic hook of only 0.5mm-2mm, which not only facilitates the installation of the positioning film, but also can stably fix the film assembly when applying the film, ensuring stability during the application process.
[0025] Long angled hook separation function: The front hook end is equipped with a 2mm-5mm long angled hook, which can effectively separate the positioning film from the protective film when the cover is opened, avoiding the problem of the positioning film falling onto the protective film. This design simplifies the operation steps, improves the efficiency of film application, and allows users to complete the entire film application process more quickly and easily.
[0026] Multi-point fixing system: In addition to the front and rear hooks, a central hook is also provided in the middle of the cover body to fix the center of the positioning film. Combined with the function of the front and rear hooks, this provides a more stable environment for film application, ensuring that the protective film can be accurately adhered to the screen, even for screens with large diagonals.
[0027] Pre-press function: There are two pressure strips on the inner rear side of the cover body, which can pre-press the back of the protective film when applying the film, promoting its adhesion to the screen first, and further improving the accuracy of the film application.
[0028] Release film unidirectional movement control: The design of the limit hook allows the release film to move only in one direction, preventing the handle of the release film from retracting into the cover, making it easier and more convenient for users to remove the release film and avoiding unnecessary trouble.
[0029] Convenient opening and closing mechanism: There are locking blocks on both sides of the front end of the lid body, and matching slots on both sides of the base shell wall, so that the lid body and the base are tightly connected and the surfaces overlap, which not only enhances the structural stability but also gives the product a good appearance design. It can also be used as a packaging box, saving space.
[0030] The base features positioning posts at both ends, allowing users to directly attach the positioning film to the base without relying on the cover itself. This design enables compatibility with more film modules, reduces user purchase costs, and increases product versatility.
[0031] Packaging box function: Due to the tight fit design between the lid and the base, the two can be used as a complete packaging box when closed, reducing the use of additional packaging materials, which is in line with the concept of environmental protection and also saves storage space for users.
[0032] In summary, the film applicator cover and film applicator provided by this utility model, through the above-mentioned innovative design, not only overcome the shortcomings of traditional film applicators, but also bring users an efficient, accurate and easy-to-use film applicator solution. This not only improves the success rate and quality of film applicator application, but also brings users a better operating experience and higher satisfaction. Attached Figure Description

Detailed Implementation
[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0049] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0050] Please see Figures 1-13 As shown, the screen protector cover includes a cover body 1, on the inside of which are a front hook 11 and a rear hook 12 for fixing and positioning the screen protector 2. The height of the front hook 11 is smaller than that of the rear hook 12, ensuring that the rear end of the screen protector 3 contacts the screen first during the application process, thereby achieving one-way air venting and reducing the generation of air bubbles. Figure 5 As shown, the end of the front hook 11 is provided with a long, angled hook 111 extending towards the front end of the lid, with a length of 2mm-5mm, to ensure that the positioning film 2 separates smoothly from the protective film 3 when the lid is opened. Figure 4 As shown, the hook of the rear hook 12 extends towards the rear end of the cover body 1, and the hook length can be 0.5mm-2mm. The hook itself has a certain elasticity. When installing the positioning film 2, first, the front end of the positioning film 2 is inserted into the front hook 11, and then a little force is applied to fix the rear end of the positioning film 2 to the rear hook 12. Figure 8 As shown. The cover body 1 also has a central hook 13 in the middle, which is used to fix the positioning hole 21 in the middle of the positioning film 2, thereby enhancing the stability during the film application process.
[0051] A pivot 17 is located at the rear end of the cover body 1 for rotatable connection with the base 5. This design allows users to easily open or close the cover while maintaining a stable connection between the cover and the base 5. Furthermore, two pressure strips 14 for pre-pressing the protective film 3 are located at the inner rear end of the cover body 1, ensuring that the rear end of the protective film 3 adheres to the screen first during application, further promoting unidirectional airflow. Figure 7 As shown, two limiting hooks 15 are provided on the inner side of the front end of the cover body 1 to lock the hanging hole 41 of the release film 4, ensuring that the release film 4 can only move in one direction and preventing the release film 4 from retracting. The through hole 18 in the center allows the user to observe the film application or press the protective film 3, increasing the transparency and convenience of the operation. Of course, the cover body 1 can be made of transparent material for easy observation.
[0052] like Figures 6-13As shown, the base 5 is equipped with a positioning device for fixing the mobile phone 6 or other electronic devices. This device can be a detachable positioning block 51 or a positioning frame injection molded with the base 5 to accommodate devices of different sizes. Positioning posts 52 for fixing the positioning film 2 are provided at both ends of the base 5. This design not only allows for direct fixing of the positioning film 2 without the cover body 1, but also accommodates other types of film assemblies, increasing the product's versatility and flexibility. The base 5 has a lens clearance hole 54 to avoid obstructing the camera of the mobile phone 6, ensuring that the camera is not blocked when applying the film. A reinforcing strip 53 is provided in the center of the base 5, improving the overall strength and durability of the base 5. Slots 55 are provided on both sides of the base 5, matching the locking blocks 16 on the cover body 1. When the cover body 1 is closed onto the base 5, the locking blocks 16 are engaged in the slots 55, ensuring a tight connection and surface overlap, thus fulfilling the function of a packaging box.
[0053] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.
[0054] like Figure 6 As shown, place the electronic device that needs to be coated on the positioning device on the base 5 to ensure that the device is stable and does not move. When installing the film assembly, the film assembly includes a positioning film 2, a protective film 3, and a release film 4 that are attached to each other. First, snap the front end of the positioning film 2 into the front hook 11, and then apply a little force to fix the rear end of the positioning film 2 into the rear hook 12. Then, fix the middle part of the positioning film 2 to the middle hook 13 to ensure stability during the film application process.
[0055] Then close the cover body 1, connecting it to the base 5 via the pivot 17 and sealing it tightly. Remove the release film 4. At this point, the pressure strip 14 will pre-press the rear end of the protective film 3, helping it achieve initial contact with the screen. The height difference design of the front hook 11 and the rear hook 12 ensures that the rear end of the protective film 3 contacts the screen first, thus achieving the effect of venting air from a single direction. Furthermore, due to the height difference between the front hook 11 and the rear hook 12, the positioning film 2 and the applied protective film 3 will have an angle at the front end, causing the positioning film 2 and the protective film 3 to automatically separate at the front end when the application is complete.
[0056] After applying the film, open the cover. Due to the action of the long angled hook 111, the positioning film 2 will be subjected to an upward force by the long angled hook 111 when the cover is opened, causing the positioning film 2 to automatically separate from the protective film 3. Figure 13 As shown.
[0057] like Figure 12 As shown, without the cover body 1, other types of film modules are directly fixed on the positioning post 52 of the base 5. The protective film 3 can be pressed with a scraper or roller to make it adhere to the screen, which increases the versatility and flexibility of the product.
[0058] In summary, the film applicator cover and the film applicator applied by this utility model, through a series of innovative designs, not only overcome the shortcomings of traditional film applicators, but also bring users an efficient, accurate and easy-to-use film applicator solution. This not only improves the success rate and quality of film applicator application, but also brings users a better operating experience and higher satisfaction.
