Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen protector auxiliary equipment technology, and in particular to a highly compatible central roller-type screen protector applicator. Background Technology

[0002] During mobile phone use, screen protectors are a common way to protect the screen from scratches and wear. However, existing screen protector application tools have many shortcomings. Almost all screen protector applicators on the market use a push-to-the-side method, which is prone to problems in practice. Because the screen protector needs to be suspended above the screen surface initially, and the roller needs to be below the screen surface to apply pressure, the positional precision of the mounting hole on the top of the screen protector is extremely important. If the mounting hole is too high, the roller will have difficulty passing over it, and even with a flexible roller, air bubbles are easily formed. If the mounting hole is too low, the screen protector may prematurely contact the screen, causing air bubbles and affecting the application result.

[0003] Furthermore, existing screen protector applicators have poor compatibility and are difficult to adapt to phones of different thicknesses. The thickness difference between regular phones and foldable phones is significant, and almost all screen protectors designed for regular phones are not directly compatible with foldable phones, failing to meet diverse market demands.

[0004] To address the aforementioned issues, this invention proposes a highly compatible center-rolling screen protector applicator, aiming to improve the success rate of screen protector application, expand its applicability, and meet the screen protector application needs of different types of mobile phones. Utility Model Content

[0005] In view of this, the present invention provides a highly compatible center-rolling screen protector applicator, which aims to improve the success rate of screen protector application, expand the scope of application, and meet the screen protector application needs of different types of mobile phones.

[0006] This invention provides a highly compatible center-rolling film applicator, comprising a base for placing the device to be applicated, a slider, and a film-pressing component. The film-pressing component is mounted on the slider and is used to compress the protective film, thereby completing the applicator operation. The slider is slidably mounted on the base, and one side of the slider can rotate around the base's slide rail axis. This design allows the film-pressing component to abut from any position on the protective film, greatly increasing the flexibility of the applicator operation and effectively reducing the formation of air bubbles.

[0007] Further describing the aforementioned solution, the pressing component is a roller, and both sides of the slider are provided with low and high mounting positions for mounting the roller. This design allows for flexible selection of the roller's mounting position based on the thickness of different phones and the actual needs of screen protector application. For example, for thinner phones, the roller can be installed at the high mounting position, allowing it to press the protective film onto the phone screen and ensuring even pressure during application; for thicker phones, the roller can be installed at the low mounting position to prevent excessive roller pressure from causing the slider to fail to engage, ensuring smooth application. In this way, this screen protector applicator can accommodate screen protectors ranging from 5mm to 12mm thick, meeting the needs of most phones.

[0008] Further description of the aforementioned solution: the base is provided with a slide rail shaft and a guide rail plate on both sides, and the guide rail plate is also provided with a recessed surface; one side of the slider is provided with a locking position, the slider is sleeved on the slide rail shaft through the locking position, and slides and rotates on the slide rail shaft; the other side of the slider is provided with an inverted buckle, the slider enters the guide rail plate from the recessed surface and is locked on the guide rail plate through the inverted buckle.

[0009] Further describing the aforementioned solution, a positioning block is installed at one end of the base. The positioning block is assembled with the sliding groove of the base via a guide strip, ensuring that the positioning block can move smoothly on the base. Two spring clips are provided on the positioning block to center the device to be applied, ensuring the accuracy of the phone's position during the application process and preventing misalignment.

[0010] Further describing the aforementioned solution, a spring is also provided between the positioning block and the base. The spring's elasticity allows the positioning block to automatically engage and position the device to be applied, improving the convenience of the application process. A locking block is also provided below the positioning block, and a corresponding latch is provided at the end of the base. When the positioning block retracts to a preset position, the latch engages with the locking block below the positioning block, thus securing the positioning block. To release the positioning block, simply press down on the latch with your finger.

[0011] Further describing the aforementioned solution, the top plate of the positioning block is equipped with hooks for fixing the film assembly, and the other side of the base is also equipped with hanging posts for fixing the film assembly. Through the hooks and hanging posts, the protective film and positioning film can be fixed in the appropriate position, preventing the film from shifting during the application process and further improving the accuracy of the application.

[0012] Further describing the aforementioned solution, an anti-disengagement buckle is also provided below the positioning block, which abuts against the bottom of the base. This design effectively prevents the positioning block from detaching from the base during movement, enhancing the stability and reliability of the entire screen protector applicator.

[0013] Further describing the aforementioned solution, the base has a pull groove at its end for easy user operation. The base also includes a tail plug inside its compartment to secure the device to be applied, further improving the stability of the phone during the screen protector application process.

[0014] Further description of the aforementioned solution: the base has a through hole in its housing to avoid damaging the phone lens during the screen protector application process.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] High film application success rate: Utilizing a central rolling application method, this directly avoids the problem of air bubbles forming on the top of the film when applying film from one end to the other, a common issue with traditional methods. The roller begins to contact the film from the middle, preventing air bubbles from forming when the top of the film is suspended in the air and comes into contact with the roller, thus significantly improving the application success rate.

[0017] Strong compatibility: The slider has low and high mounting positions on both sides for mounting the roller, which can be adapted to mobile phones with a thickness of 5-12 mm, meeting the screen protector needs of most mobile phones, including ordinary mobile phones and foldable screen phones, effectively solving the problem that traditional screen protector tools cannot be compatible with mobile phones of different thicknesses.

[0018] Flexible and convenient operation: One side of the slider can rotate around the base slide rail axis, allowing the film pressing component to abut from any position on the protective film, facilitating flexible adjustment of the roller's starting position according to the actual film application situation. The positioning block automatically abuts and positions the film-to-be-applied device via a spring, further enhancing operational convenience.

[0019] Stable and reliable: The base and slider use a sliding rail shaft and guide rail plate with an inverted connection, ensuring the stability of the slider's sliding and rotation. An anti-disengagement buckle is installed under the positioning block to prevent it from falling off the base during movement. The base's housing includes a tail plug to secure the phone and a through hole to avoid damaging the phone's lens during screen protector application, enhancing overall stability and reliability.

[0020] Precise positioning: Two spring clips on the positioning block center the device to be applied with the screen protector. The hook on the top plate of the positioning block and the hanging post on the other side of the base are used to fix the screen protector assembly, ensuring that the mobile phone and screen protector are accurately positioned during the application process, preventing the screen protector from shifting and improving the accuracy of the application.

In this way, this screen protector applicator can adapt to screen protectors for mobile phones 6 with thicknesses ranging from 5 mm to 12 mm, meeting the screen protector application needs of the vast majority of mobile phones 6. Figure 4 , 7As shown, the base 1 has a slide rail shaft 12 and a guide rail plate 18 on both sides, and the guide rail plate 18 also has a recessed surface 16. The slider 2 has a locking position 24 on one side, through which the slider 2 is fitted onto the slide rail shaft 12 and slides and rotates on the slide rail shaft 12. The other side of the slider 2 has an inverted buckle 23, through which the slider 2 enters the guide rail plate 18 from the recessed surface 16 and is engaged with the guide rail plate 18 by the inverted buckle 23. The end of the base 1 has a pull groove 14 for easy user operation. The base 1 also has a tail plug 15 inside its accommodating compartment for fixing the device to be applied, further improving the stability of the phone 6 during the application process. The base 1 also has a through hole 19 inside its accommodating compartment to avoid damaging the phone 6 lens during the application process.

[0037] like Figures 8 to 11 As shown, a positioning block 4 is installed at one end of the base 1. The positioning block 4 is assembled with the sliding groove 10 of the base 1 via a guide strip 46, ensuring that the positioning block 4 can move smoothly on the base 1. Two spring pieces 41 are provided on the positioning block 4 to center the device to be applied, ensuring the positional accuracy of the mobile phone 6 during the application process and preventing the application from shifting. A spring 5 is also provided between the positioning block 4 and the base 1, and corresponding spring hooks 17 are provided on the positioning block 4 and the base 1. The elastic force of the spring 5 enables the positioning block 4 to automatically abut and position the device to be applied, improving the convenience of the application operation. A locking block 45 is also provided below the positioning block 4, and a corresponding buckle 13 is provided at the end of the base 1. When the positioning block 4 retracts to the preset position, the buckle 13 locks the locking block 45 below the positioning block 4, thus fixing the positioning block 4. To release the positioning block 4, simply press down on the buckle 13. A hook 42 for fixing the film assembly is provided on the top of the positioning block 4, and a hanging post 11 for fixing the film assembly is also provided on the other side of the base 1.

An anti-detachment buckle 44 is also provided below the positioning block 4, which abuts against the bottom of the base 1. This design effectively prevents the positioning block 4 from falling off the base 1 during movement, enhancing the stability and reliability of the entire film application device.

[0038] 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.

[0039] When using this screen protector applicator, first slide slider 2 to the notch at the end of guide rail 18, then flip it to one side of base 1. Next, pull positioning block 4 back. Figure 10As shown, the buckle 13 engages with the locking block 45 below the positioning block 4, thus securing the positioning block 4. Next, place the phone 6 (to be fitted with a screen protector) into the receiving compartment of the base 1, secure the phone 6 using the tail plug 15, and then press the buckle 13. The buckle 13 disengages from the locking block 45 below the positioning block 4, and the positioning block 4, under the tension of the spring 5, abuts against the phone 6. Figure 11 As shown, the spring piece 41 automatically centers the mobile phone 6 and abuts the end of the mobile phone 6 on the base 1 of the abutment part 43, so that the mobile phone 6 is fixed on the base 1.

[0040] Then, the film assembly with protective film 7, positioning film 8, and release film is hung on hook 42 of positioning block 4 and hanging post 11 of base 1, as follows. Figure 4 As shown.

[0041] Choose the appropriate installation position for the roller 3 based on the thickness of the phone 6. For a thinner phone 6, install the roller 3 at the high mounting position 22 of the slider 2; for a thicker phone 6, install it at the low mounting position 21. After installing the roller 3, flip the slider 2. In this embodiment, when flipping, find the recessed surface 16 of the guide rail 18 so that the buckle 23 enters the guide rail 18 from the recessed surface 16 and engages with it. This allows the roller 3 to abut against the protective film 7 from the middle. After removing the release film, slide the slider 2. The roller 3 slides back and forth, squeezing the protective film 7 during the sliding process. Air is squeezed out from both sides, and the protective film 7 gradually adheres to the screen of the phone 6. Figure 3 As shown.

[0042] After the screen protector is applied, slide the slider 2 to the notch at the end of the guide rail 18, flip it to the side of the base 1, move the positioning block 4 back and lock it onto the buckle 13, and then take out the phone 6.

[0043] Throughout the entire screen protector application process, the anti-dislodgement buckle 44 below the positioning block 4 remains in contact with the bottom of the base 1 to prevent the positioning block 4 from falling off; the through hole 19 in the housing of the base 1 can avoid the lens of the mobile phone 6, thus preventing damage to the lens; the pull groove 14 makes it convenient for users to operate the screen protector applicator, improving ease of use.
