Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, specifically a convenient pull-out film applicator. Background Technology

[0002] In the use of modern electronic devices, applying screen protectors to mobile devices such as smartphones is a crucial step that users are generally concerned about. High-quality screen protectors not only protect the screen from scratches and wear but also enhance the user experience. However, the current manual application process has many problems, such as difficulty in precise alignment, the formation of air bubbles, and dust accumulation. These issues result in a low success rate, consume a lot of time and effort, and seriously affect the user experience.

[0003] To address the technical challenges of manual screen protector application, various auxiliary tools have emerged on the market. Traditional screen protector application aids often employ simple frame structures, using slots or clips to position the screen and screen protector. However, in practical use, these devices suffer from inconvenience in placing and removing the screen protector, and struggle to ensure stable positioning of the protector during application. This leads to the screen protector easily shifting during the application process, reducing accuracy and efficiency.

[0004] Therefore, there is an urgent need to design a new type of film application auxiliary device that can effectively solve the problems of unstable protective film positioning and inconvenient operation in the existing technology, and provide users with an efficient, convenient and accurate film application solution. Utility Model Content

[0009] The placement opening is located on the first wide side, and the pull-out opening is located on the second wide side.

[0010] As a further embodiment of this utility model: the side also includes a first long side and a second long side arranged along the length direction of the positioning frame;

[0011] The first and second long sides both extend inward to form a limiting edge, so as to limit the protective film to the positioning space.

[0012] As a further embodiment of this utility model: the second wide side extends inward to form a pressing structure.

[0013] As a further embodiment of this utility model: the limiting edge extends inward to form a reinforcing rib connected to the pressing structure.

[0014] As a further embodiment of this utility model: the connection between the reinforcing rib and the pressing part is smoothly transitioned.

[0015] As a further embodiment of this utility model: the pressing part is in the shape of a fingerprint outline.

[0016] As a further embodiment of this utility model: a blocking protrusion corresponding to the pull-out opening is provided on the second wide side.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1) The stepped structure and positioning space work together to accurately position the screen and the protective film, effectively solving the problem of difficult alignment in traditional screen protector application and improving the accuracy of application;

[0029] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 In this embodiment of the utility model, a convenient pull-out screen protector is used to assist the screen to be protected during the screen protector application process, and is particularly suitable for mobile phone screens. It includes a positioning frame 1, the positioning frame 1 having a side extending along its edge, and a step structure 2 for abutting the edge of the screen to be protected between the positioning frame 1 and the side. A positioning space 3 for positioning the protective film is formed between the step structure 2, the side and the positioning frame 1.

[0031] An opening 4 communicating with the positioning space 3 is provided on one side of the surface of the positioning frame 1 so that the protective film can enter the positioning space 3 along the opening 4. The positioning frame 1 has a pull-out opening 5 corresponding to the protective film on the side opposite to the opening 4.

[0032] In this utility model, the height and width of the step structure 2 are precisely designed to accurately fit the edge of the screen to be covered. When the screen protector is placed on the screen, it can be regarded as being snapped onto the screen. The step structure 2 fits tightly against the edge of the screen through physical contact, providing a stable support point for the entire screen protector. Combined with the mobile phone screen, it restricts the horizontal movement of the screen protector, ensuring that the relative position of the screen protector and the screen is accurately fixed, thus achieving initial positioning.

[0033] The positioning frame 1 and the side together form a regular frame. The positioning frame 1 surrounds the screen, and the side is perpendicular to the positioning frame 1, forming a clear spatial boundary. The stepped structure 2 works in conjunction with the positioning frame 1 and the side to limit the protective film in three dimensions (horizontal, vertical and depth directions), so that the protective film is in a precise preset position within the positioning space 3, ensuring the stability of the protective film during the application process and preventing it from shifting or shaking.

[0034] The placement opening 4 is located on one side of the surface of the positioning frame 1. Its width is slightly larger than the width of the protective film, so that the protective film can smoothly enter the positioning space 3 along the placement opening 4. During the entry process, it will not be obstructed due to the opening being too narrow, nor will it be skewed when the opening is too wide.

[0035] The pull-out opening 5 is located on the side opposite to the placement opening 4. The placement opening 4 and the pull-out opening 5 are on the same straight line. When it is necessary to pull out the protective film (the release film 15 below it) for application, the user can apply force from the pull-out opening 5. Due to the good straightness of the channel formed by the two, the protective film (the release film 15 below it) is subjected to uniform friction during the extraction process, and can be smoothly extracted from the positioning space 3. During the extraction process, it always stays within the path defined by the positioning space 3, thereby ensuring that the protective film (the main film 14) can accurately cover the screen. That is, by forming a path through the positioning space 3, based on the simple linear motion principle, the user can easily put the protective film from the placement opening 4 into the positioning space 3 and then pull it out from the pull-out opening 5, realizing the pull-out movement of the protective film within the positioning space 3. The whole process is smooth and easy to control.

[0036] In summary, the step structure 2, in conjunction with the positioning space 3, can accurately position the screen and the protective film, effectively solving the problem of difficult alignment in traditional screen protector application and improving application accuracy. The placement opening 4 and the pull-out opening 5 simplify the placement and removal of the protective film, making it more convenient to operate than traditional devices and improving application efficiency. The stable positioning space 3 reduces the possibility of protective film misalignment during application, lowers the probability of air bubbles, and ensures application quality.

[0037] In this embodiment of the utility model, the side includes a first wide side 6 and a second wide side 7 arranged along the width direction of the positioning frame 1;

[0038] The placement opening 4 is located on the first wide side 6, and the pull-out opening 5 is located on the second wide side 7.

[0039] The sides are divided into a first wide side 6 and a second wide side 7, which are set along the width direction of the positioning frame 1 to form the side boundary of the positioning space 3. The placement opening 4 is opened on the first wide side 6, and the pull-out opening 5 is opened on the second wide side 7. The line connecting the two corresponds to the longer side of the positioning frame 1, that is, the length direction in the usual sense. In other words, a through channel is formed in this length direction. Based on the principle of linear motion guidance, it is convenient for the protective film to be put in from the placement opening 4 and pulled out from the pull-out opening 5, ensuring that the protective film maintains a linear motion trajectory during the pulling process and reducing the possibility of deviation.

[0040] In this embodiment of the present invention, the side also includes a first long side 8 and a second long side 9 arranged along the length direction of the positioning frame 1;

[0041] The first long side 8 and the second long side 9 both extend inward to form a limiting edge 13, so as to limit the protective film to the positioning space 3 through the limiting edge 13.

[0042] The limiting edge 13 is formed by the first long side 8 and the second long side 9 extending inward and located on the edge surface of the positioning space 3. Based on the principle of physical blocking, it forms a barrier through its own structure to prevent the protective film from leaving the positioning space 3 during placement or pulling. Together with the positioning frame 1, it ensures that the protective film is always within the positioning space 3, providing a guarantee for accurate film application.

[0043] In this embodiment of the present invention, the second wide side 7 extends inward to form a pressing structure 10.

[0044] Understandably, the protective film includes a main film 14, an upper release film 16 connected to the upper surface of the main film 14, a lower release film 15 connected to the lower surface of the main film 14, and a pull strip 17 connected to one side of the lower release film 15. During use, the protective film is inserted into the positioning space 3 along the placement opening 4 so that the protective film can be aligned with the screen. At this time, the pull strip 17 is extended to the outside through the pull-out port 5, that is, outside the positioning frame 1. By pulling the pull strip 17, the lower release film 15 is detached from the main film 14 and pulled out through the pull-out port 5. Combined with the design of the pressing structure 10, when external force is applied to the pressing structure 10, the pressure can be transmitted to the main film 14, so that one end of the main film 14 located on the pressing structure 10 is attached to one end of the screen, and automatic air release is performed to adhere it to the screen, thereby realizing the film application action. Finally, the positioning frame 1 is removed and the upper release film 16 is peeled off from the main film 14.

[0045] In this embodiment of the present invention, the limiting edge 13 extends inward to form a reinforcing rib 11 connected to the pressing structure 10; the connection between the reinforcing rib 11 and the pressing part is smoothly transitioned.

[0046] When the user applies pressure to the pressing structure 10, the reinforcing rib 11 can distribute the pressure more evenly throughout the positioning space 3, avoiding excessive local stress that could lead to structural deformation or damage. At the same time, the smooth transition design between the reinforcing rib 11 and the pressing structure 10 reduces stress concentration points, ensures smooth force transmission when under stress, and enhances the overall structural stability and compressive strength. In addition, as a connecting component between the limiting edge 13 and the pressing structure 10, the reinforcing rib 11 strengthens the synergistic effect between the two, enabling the pressing structure 10 to better fix the protective film by driving the limiting edge 13 through the reinforcing rib 11 during the application of force, thus improving the stability of the film application operation.

[0047] In this embodiment of the invention, the pressing part is shaped like a fingerprint outline.

[0048] The fingerprint contour shape can precisely fit the physiological curvature of the fingertip, so that when the user applies pressure, a close and comfortable contact can be formed between the finger and the pressing part; in addition, the fingerprint contour shape has an operation guide function, and the unique fingerprint contour shape can help users intuitively determine the pressing position, simplify the operation process, and reduce the difficulty of applying the screen protector.

[0049] In this embodiment of the present invention, a blocking protrusion 12 corresponding to the pull-out opening 5 is provided on the second wide side 7.

[0050] Designed based on the principle of physical limiting and anti-detachment, the core function of the blocking protrusion 12 is to ensure that the main film 14 is always within the effective limiting range of the positioning space 3 during the process of completely separating from the lower release film 15, so as to avoid the main film 14 losing the constraint of the positioning frame 1 and leaving the predetermined position due to the removal of the lower release film 15, thereby facilitating the normal operation of film application.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
