Description

Technical Field

[0001] This utility model relates to the technical field of screen protector application tools for electronic devices, and more specifically, to a screen protector application auxiliary tool. Background Technology

[0002] With the widespread use of electronic devices such as mobile phones and tablets, users often apply tempered glass screen protectors to protect their displays. To make self-application easier, screen protectors are usually accompanied by a device-specific positioning tool. Users simply place the device into the tool, then position the protective film, peel off the backing film of the tempered glass, press the film down to adhere it to the display, and finally peel off the outer protective film.

[0003] For example, Chinese patent document CN222663891U discloses a magnetic film applicator. Its specification and accompanying drawings disclose that the protective film includes PET film and tempered glass film. The PET film has a foolproof groove. The magnetic film applicator includes a top plate, and a bottom plate is detachably connected to the bottom of the top plate. The two can be connected by a snap-fit. A first clamping rod is fixedly installed on the top surface of the top plate. The bottom of the top plate has a receiving cavity. A limit plate is slidably connected in the receiving cavity. A tension plate is fixedly installed at one end of the limit plate that extends out of the receiving cavity. A second clamping rod is fixedly installed on the top of the tension plate. Foolproof protrusions that match the shape and position of the foolproof groove are fixedly installed on the first and second clamping rods.

[0004] However, during the actual application process, the two ends of the PET film are positioned behind the anti-foolproof protrusions, causing the entire film to be stretched taut. At this time, there is a gap between the tempered glass film and the display screen, requiring manual pressing of the entire film to adhere it to the display screen. However, when the entire film is stretched taut, the tempered glass film can only be adhered to the pressed area during the adsorption process, while other areas are stretched flat and cannot automatically adhere. At this point, the user needs to peel off the surface PET film and smooth the tempered glass film over the entire display screen area again, which easily leads to air bubbles. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a film application auxiliary tool to solve the problems in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a film application auxiliary tool, including a box body, a limiting frame provided on the box body, the limiting frame including a receiving groove for placing the film application device, a protective film positioning platform provided at one end of the receiving groove, a plurality of positioning protrusions provided on the protective film positioning platform, a buffer protrusion provided on the side of the protective film positioning platform near the receiving groove, a buffer surface provided on the upper surface of the buffer protrusion, the buffer surface being inclined downward from the protective film positioning platform toward the receiving groove.

[0007] In the above-mentioned film application auxiliary tool, the inner walls on both sides of the receiving groove are provided with raised first protective film support convex walls, and the upper surface of the first protective film support convex walls is higher than the surface of the device to be applied with film.

[0008] In the above-mentioned film application aid tool, the upper surface of the first protective film support protrusion and the protective film positioning platform are located on the same plane.

[0009] In the aforementioned film application aid, the upper surface of the first protective film support convex wall is higher than the inclined downstream end surface of the buffer surface.

[0010] In the above-mentioned film application auxiliary tool, the limiting frame is surrounded by a barrier, and the height of the barrier is higher than the upper surface of the first protective film support protrusion and the protective film positioning platform.

[0011] In the above-mentioned film application auxiliary tool, a notch is provided on the side of the enclosure away from the protective film positioning platform, and a second protective film support protrusion is provided on the side of the notch near the receiving groove.

[0012] In the aforementioned film application aid, a lid is provided on one side of the box body, and a pressure strip is provided on the side of the lid facing the folding direction of the box body.

[0013] In the aforementioned film application aid, the pressure strip is arranged horizontally or vertically.

[0014] In the aforementioned film application aid, the pressure strip is made of sponge or silicone.

[0015] The beneficial effects of this utility model are that multiple positioning protrusions are used to position the PET film, so that the buffer surface of the buffer protrusion supports the lower end of the PET film. Since the buffer surface is inclined, the distance between the positioning protrusion of the PET film and the edge of the tempered glass film is increased. During the film application process, after the tempered glass film is pressed down and adsorbed onto the surface of the device to be applied, the PET film at the upper end of the buffer surface is also pressed down and bent. Compared with existing auxiliary tools, the entire PET film is in a downward buffered state, which allows the entire tempered glass film to be better and more completely and quickly adsorbed onto the entire display screen surface. This prevents the phenomenon that the tempered glass film can only be partially adsorbed due to the PET film being positioned and tightened. The film application process is smoother, and air bubbles are prevented from forming when the tempered glass film is lifted due to being in a taut state. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1 Combination Figures 1 to 5The illustrated film application aid includes a box body 1, with a limiting frame 4 on the box body 1. The limiting frame 4 includes a receiving groove 6 for placing the film application device 13. A protective film positioning platform 8 is provided at one end of the receiving groove 6. The protective film positioning platform 8 is provided with multiple positioning protrusions 9 for positioning and placing the protective film packaging film 5. The protective film packaging film 5 includes a PET film 14. A tempered glass film is provided at the lower end of the PET film 14. A bottom film is provided at the lower end of the tempered glass film. First support wings 16 are provided on both sides of the PET film 14. Multiple positioning holes 15 are provided at one end of the PET film 14, and a second support wing 17 is provided at the other end.

[0025] A buffer boss 10 is provided on the side of the protective film positioning platform 8 near the receiving groove 6. The upper surface of the buffer boss 10 is provided with a buffer surface, which is inclined downward from the protective film positioning platform 8 toward the receiving groove 6. In this embodiment, multiple positioning protrusions 9 are used to position the positioning holes 15 of the PET film 14, so that the buffer surface of the buffer boss 10 supports the lower end of the PET film 14. Since the buffer surface is inclined, the distance between the positioning protrusions 9 of the PET film 14 and the edge of the tempered glass film is increased. During the film application process, after the tempered glass film is pressed down and adsorbed onto the surface of the film application device 13, the PET film 14 at the upper end of the buffer surface is also pressed down and bent. Compared with existing auxiliary tools, the entire PET film 14 is in a downward buffered state, which allows the entire tempered glass film to be better and more completely and quickly adsorbed onto the entire display screen surface. This prevents the phenomenon that the tempered glass film can only be adsorbed part of the screen due to the PET film 14 being positioned and tightened. The film application process is smoother, and air bubbles are prevented from forming when the tempered glass film is lifted due to the taut state.

[0026] In this embodiment, the inner walls of the receiving groove 6 on both sides are provided with raised first protective film support convex walls 7. The upper surface of the first protective film support convex walls 7 is higher than the surface of the film-applying device 13. The upper surfaces of the first protective film support convex walls 7 and the protective film positioning platform 8 are located on the same plane. After the film-applying device 13 is placed into the receiving groove 6, the surface of the film-applying device 13 is lower than the upper surface of the first protective film support convex walls 7. After the positioning hole 15 of the PET film 14 is fitted with the positioning protrusion 9, first support wings 16 are provided on both sides to support the upper surface of the first protective film support convex walls 7, so that the entire protective film packaging film 5 is suspended above the film-applying device 13.

[0027] In this embodiment, the limiting frame 4 is surrounded by a barrier 12. The height of the barrier 12 is higher than the upper surface of the first protective film support protrusion 7 and the protective film positioning platform 8. This allows the entire protective film packaging film 5 to be stably contained within the barrier 12 during packaging and transportation, preventing the entire protective film packaging film 5 from being crushed.

[0028] Similarly, a notch is provided on the side of the enclosure 12 away from the protective film positioning platform 8, and a second protective film support protrusion 11 is provided on the side of the notch near the receiving groove 6; the second support wing 17 of the PET film 14 is supported by the second protective film support protrusion 11 to prevent the end of the protective film packaging film 5 away from the positioning protrusion 9 from losing support.

[0029] It is worth noting that the upper surface of the first protective film support convex wall 7 is higher than the inclined downstream end surface of the buffer surface; this allows the edge of the PET film 14 to bend downwards after the tempered film is pressed down, so as to facilitate the adsorption of the tempered film. Moreover, before being pressed down, the entire protective film packaging film 5 can be stably positioned and suspended above the film application device 13.

[0030] In this embodiment, a lid 2 is provided on one side of the box body 1, and a pressure strip 3 is provided on the side of the lid 2 facing the folding direction of the box body 1; after the lid 2 is folded towards the box body 1, the lid closes on the enclosure 12, so that the protective film packaging film 5 can be prevented from being damaged during transportation.

[0031] The pressure strip 3 is horizontally positioned and is made of sponge or silicone. During transportation, since the receiving slot 6 does not contain the film applicator 13, when the pressure strip 3 presses on the protective film packaging film 5, the protective film packaging film 5 is pressed down by the buffer boss 10, the first protective film support protrusion 7, and the second protective film support protrusion 11, preventing the protective film packaging film 5 from shaking excessively during transportation. When film application is required, after the film applicator 13 is placed in the receiving slot 6, the box cover 2 is folded over, causing the pressure strip 3 to press against the protective film packaging film 5. At this time, the bottom film is pulled out, and the tempered glass film is adsorbed onto the display screen under the pressure of the pressure strip 3. Afterward, without further pressure, after a certain period of time, the tempered glass film is automatically and completely adsorbed onto the display screen, and then the box cover 2 can be opened, and the PET film 14 can be peeled off from the second support wing 17 at the notch.

[0032] Example 2 like Figure 6 As shown, the difference between this second embodiment and the first embodiment is that the pressure strip 3 is set vertically, so that the pressure strip 3 can be pressed down along the length of the display screen, causing the adsorption surface of the tempered glass film to adsorb on both sides, instead of pressing down one end and adsorbing on the other end as in the first embodiment.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
