Description

A self-pressing mobile phone screen protector applicator Technical Field

[0001] This utility model relates to the field of mobile phone screen protector application tools, and in particular to a self-pressing mobile phone screen protector applicator. Background Technology

[0002] With the widespread use of smartphones, screen protectors have become an indispensable accessory. They are applied to the surface of the phone screen to effectively prevent scratches or cracks. Currently, commercially available screen protectors usually come with application tools, such as positioning frames and guide brackets, to help users achieve precise alignment between the screen protector and the screen.

[0003] In existing technologies, mainstream screen protector application assistance solutions mainly employ a pull-out plate or pull-out strip structure design. Specifically, a release film is covered on the screen protector, and a pull plate or strip is fixedly connected to this release film. During the application process, the release film is placed between the screen protector and the screen to form an isolation layer. After alignment is achieved, the user peels off the release film completely by pulling it out, thus allowing the screen protector to make initial contact with the screen. While this design solves the alignment problem of traditional manual screen protector application, it still has significant drawbacks in practical applications:

[0004] After the release liner is removed, the screen protector only adheres to the screen through its own adhesive, often resulting in uneven gaps and residual air between the protector and the screen. Due to the lack of continuous and stable pressure, the protector cannot automatically press together, requiring the user to manually release air by pressing with their fingers or scraping. This process is not only cumbersome but also prone to leaving air bubbles due to improper handling, severely impacting the success rate of the application and the user experience. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a self-pressing mobile phone screen protector applicator. This applicator can automatically press and vent air during the application of the screen protector, making it simple and convenient to operate, reducing the failure rate of screen protector application, and improving the user experience.

[0006] To achieve the above objectives, the present invention provides a self-pressing mobile phone screen protector, comprising an inner frame, an outer frame, and a mobile phone screen protector. The inner frame includes a base plate and a positioning frame disposed on the base plate for positioning the mobile phone. The mobile phone screen protector is detachably fixed within the positioning frame of the base plate. The outer frame is movably fitted onto the outside of the inner frame. The base plate has at least one through hole at the position corresponding to the mobile phone screen protector. The inner side of the outer frame is provided with a first elastic member and a second elastic member. The first elastic member is disposed between the contact surfaces of the outer frame and the inner frame, providing elastic movement space between the outer frame and the inner frame. The second elastic member is located at the through hole, allowing the second elastic member to pass through the through hole and press against the mobile phone screen protector.

[0007] As a further improvement of this utility model, the first elastic member is located at the top of both the outer frame and the inner frame, so that there is an elastic movement space between the tops of the outer frame and the inner frame, and the bottoms of the outer frame and the inner frame are bonded together.

[0008] As a further improvement of this utility model, the top and bottom of the outer frame are respectively provided with fasteners, and the top and bottom of the inner frame are respectively provided with fastening grooves. The outer frame and the inner frame are detachably fastened together by the cooperation of the fasteners and the fastening grooves, and there is a movable space between the fasteners and the fastening grooves at the top of the outer frame and the inner frame.

[0009] As a further improvement of this utility model, both the first elastic element and the second elastic element are made of elastic sponge.

[0010] As a further improvement of this utility model, an adhesive layer is provided on the surface of the base plate, and the mobile phone film is detachably fixed to the base plate through the adhesive layer.

[0011] As a further improvement of this utility model, the inner frame is provided with positioning posts to facilitate the positioning of the mobile phone film.

[0012] As a further improvement of this utility model, the inner frame is provided with a pull-out groove to facilitate the removal of the screen protector.

[0013] As a further improvement of this utility model, the inner frame is provided with an upper locking position and a lower locking position on the upper and lower sides of the mobile phone film position, respectively. The upper locking position and the lower locking position respectively lock the upper and lower sides of the mobile phone film to prevent the mobile phone film from falling off.

[0014] As a further improvement of this utility model, the lower card slot is provided with an inclined surface, the bottom side of the inclined surface is provided with a recessed card groove, and the mobile phone film is provided with a card receiving part corresponding to the position of the card groove.

[0015] The beneficial effects of this utility model are as follows: This utility model achieves automatic pressing and air venting of the screen protector through the cooperation of the inner frame, outer frame, first elastic element, and second elastic element. During application, the first elastic element provides elastic movement space for the inner frame. After the phone is placed and positioned within the inner frame, the weight of the phone causes the inner frame to naturally move downwards. Simultaneously, the second elastic element applies upward pressure to the screen protector. This coordinated action automatically presses the screen protector onto the phone screen, automatically venting air, thus effectively preventing air bubble residue and improving the success rate of application. Users can complete the application without manually pressing the screen protector, significantly reducing the difficulty of operation. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] As shown in Figures 1 and 2, a self-pressing mobile phone screen protector includes an inner frame 1, an outer frame 2, and a mobile phone screen protector 3.

[0021] The inner frame 1 includes a base plate 11 and a positioning frame 12 disposed on the base plate 11. The positioning frame 12 is used for positioning the mobile phone. An adhesive layer 13 is disposed on the surface of the base plate 11 located inside the positioning frame 12. The mobile phone film 3 is detachably fixed to the positioning frame 12 of the base plate 11 through the adhesive layer 13, and the adhesive layer 13 can prevent the mobile phone film 3 from falling off during the application process. The base plate 11 is provided with a through hole 14 at the position corresponding to the mobile phone film 3.

[0022] The outer frame 2 is movably fitted onto the outside of the inner frame 1. A first elastic element 21 and a second elastic element 22 are provided on the inner side of the outer frame 2. Both elastic elements are made of elastic sponge material and are fixed to the outer frame 2 by adhesive. The first elastic element 21 is located between the top contact surfaces of the outer frame 2 and the inner frame 1, allowing for elastic movement between their tops. The second elastic element 22 is located at the through hole 14, allowing it to pass through the through hole 14 and press against the screen protector 3. The bottoms of the outer frame 2 and the inner frame 1 are bonded together, allowing the outer frame 2 and the inner frame 1 to move around with their bottoms as a fulcrum.

[0023] The outer frame 2 has fasteners 23 at its top and bottom, and the inner frame 1 has fastening slots 15 at its top and bottom. The outer frame 2 and the inner frame 1 are detachably fastened together by the cooperation of the fasteners 23 and the fastening slots 15. There is room for movement between the fasteners 23 and the fastening slots 15 at the top of both the outer frame 2 and the inner frame 1, ensuring that the tops of both the outer frame 2 and the inner frame 1 can move, while the bottoms of both the outer frame 2 and the inner frame 1 are tightly fastened together. This detachable structure of the outer frame 2 and the inner frame 1 achieves the effect of saving production costs. The outer frame 2 is produced with uniform specifications, while the size of the positioning frame 12 of the inner frame 1 is adjusted according to the size of the mobile phone. Only the position of the fastening slots 15 needs to be kept consistent to achieve universal adaptation. There is no need to develop separate molds for the outer frame 2 for mobile phones of different sizes, which greatly saves production costs.

[0024] The screen protector 3 uses either a strip-type or a plate-type design, both currently available on the market. These two types of screen protectors 3 employ different positioning methods. The strip-type design involves a strip and positioning holes on the screen protector 3, with positioning posts on the applicator. The screen protector 3 is positioned using these positioning holes and posts, and the release film is then removed by pulling the strip. The plate-type design involves a plate on the screen protector 3, which is then inserted into the pull-out groove of the applicator to achieve positioning. Finally, the plate is pulled out of the pull-out groove, along with the release film. In this embodiment, the inner frame 1 is provided with positioning posts 16 for easy positioning of the screen protector 3 and pull-out grooves 17 for easy removal of the screen protector 3, accommodating both different types of screen protectors 3.

[0025] In addition, the inner frame 1 has an upper locking slot 18 and a lower locking slot 19 on the upper and lower sides of the screen protector 3, respectively. The upper locking slot 18 and the lower locking slot 19 respectively lock the upper and lower sides of the screen protector 3 to prevent the screen protector 3 from falling off. Specifically, the lower locking slot 19 has a slope 191, and the bottom side of the slope 191 has a recessed slot 192. The screen protector 3 has a locking part 31 corresponding to the position of the slot 192. When the screen protector 3 is placed, the locking part 31 slides into the slot 192 along the slope 191, and the screen protector 3 is fixed by the slot 192. At this time, even if the inner frame 1 is flipped, the screen protector 3 will not easily fall off.

[0026] In use, first fix the screen protector 3 to the positioning frame 12 of the inner frame 1 using the adhesive layer 13, and then place the phone onto the positioning frame 12 for positioning. After positioning, peel off the release film using the pull strip or pull plate on the screen protector 3. The weight of the phone will cause the inner frame 1 to move downwards. At this time, the second elastic element 22 applies upward pressure to the screen protector 3 through the through hole 14, causing the screen protector 3 to automatically press against the phone screen and automatically expel air, thus achieving automatic screen protector application.

[0027] The above-described embodiments are only for illustrative purposes and are not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
