Description

Technical Field

[0001] This utility model belongs to the field of screen grinding fixture technology, and in particular relates to a waterproof mold for mobile phone or tablet screens that does not require glue application. Background Technology

[0002] In current technology, due to the rapid pace of mobile phone and tablet upgrades (with flagship models typically released annually), users frequently replace their phones and tablets due to hardware and software advancements, leading to a surge in secondhand devices. Refurbishing these devices often requires screen polishing, which is less costly than simply replacing the screen. Existing screen polishing fixtures typically involve directly embedding the phone or tablet's back cover into the fixture, requiring adhesive to seal the screen and fixture. This prevents water from seeping into the fixture during polishing, affecting the phone's or tablet's functionality, and also prevents water from damaging the phone by seeping into the gaps between the screen and the back cover. However, existing fixtures are complex to operate, requiring adhesive application, and disassembly is inconvenient after polishing, leaving adhesive marks on the screen that need manual removal, which is time-consuming and reduces overall polishing efficiency. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a glue-free waterproof mold for mobile phone or tablet screens, which can easily achieve waterproof sealing and easy disassembly and assembly, thereby improving the efficiency of polishing work.

[0004] The present invention is implemented as follows:

[0005] A waterproof mold for a mobile phone or tablet screen without adhesive application includes: a front cover, a sealing gasket, and a back cover; the back cover has a space inside to accommodate a mobile phone or tablet, the mobile phone or tablet is placed in the back cover, the front cover has an opening to expose the screen of the mobile phone or tablet, and a receiving and mounting groove for the sealing gasket is arranged around the front cover near the opening, the sealing gasket is placed in the receiving and mounting groove, the front cover presses the sealing gasket tightly and is detachably fixed to the back cover by locking screws, the sealing gasket is pressed between the front cover and the back cover and between the front cover and the edge of the mobile phone or tablet;

[0006] Screw holes are provided around the front and rear covers, and the locking screws are used to fasten the front and rear covers.

[0007] The sealing gasket has a ring structure, and the opening of the inner ring is smaller than or equal to the size of the mobile phone or tablet screen.

[0008] Multiple reinforcing ribs are provided on the outer surface of the back cover to enhance its rigidity, and the reinforcing ribs are distributed horizontally and vertically on the outer surface of the back cover.

[0009] The waterproof mold is a square structure with at least four screw holes on the long side and at least two screw holes on the short side.

[0010] This utility model embodiment, by providing a front cover, a sealing gasket, and a back cover, allows the entire mobile phone or tablet to be assembled within the space inside the front and back covers. The sealing gasket, combined with screws, secures the internal space of the front and back covers, achieving a waterproof seal. No additional glue application is required, and no additional residual glue removal is needed after screen polishing. This reduces the overall polishing difficulty and complexity, optimizes the screen polishing process, and simplifies the process. The front and back covers are detachably connected by screws, making assembly and disassembly faster, saving labor costs, and improving overall polishing efficiency. The sealing gasket groove inside the front cover effectively positions the gasket, working in conjunction with the front cover and the edges of the mobile phone or tablet to achieve a waterproof seal. The outer surface of the back cover has reinforcing ribs, increasing its rigidity and preventing deformation during polishing. This effectively secures the mobile phone or tablet, ensuring a better polishing effect and improving the quality of screen polishing. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0017] like Figures 1 to 4As shown, a waterproof mold for a mobile phone or tablet screen without adhesive application includes: a front cover 1, a sealing gasket 2, and a back cover 4; the back cover has a space 401 for accommodating a mobile phone or tablet 3, the mobile phone or tablet is placed in the back cover, the front cover has an opening for exposing the mobile phone or tablet screen, and a receiving slot 101 for the sealing gasket is provided around the front cover near the opening, the sealing gasket is placed in the receiving slot, the front cover presses the sealing gasket tightly and is detachably fixed to the back cover by locking screws 5, the sealing gasket is pressed between the front cover and the back cover and between the front cover and the edge of the mobile phone or tablet;

[0018] Screw holes are provided around the front and rear covers, and the locking screws are used to fasten the front and rear covers.

[0019] The sealing gasket has a ring structure, and the opening of the inner ring is smaller than or equal to the size of the mobile phone or tablet screen.

[0020] In the figure, multiple reinforcing ribs 402 are provided on the outer surface of the back cover to enhance its rigidity, and the reinforcing ribs are distributed horizontally and vertically on the outer surface of the back cover.

[0021] In the figure, the waterproof mold is a square structure with at least four screw holes on the long side and at least two screw holes on the short side.

[0022] The sealing gasket is mainly used to seal the gap between the phone screen and the front cover, as well as the gap between the front cover and the back cover. The sealing gasket is generally made of rubber. In this way, except for the screen, all other parts of the phone are sealed in the mold. Only the screen is exposed through the opening in the front cover so that the screen can be polished.

[0023] When using the device, place the phone or tablet to be polished into the space of the back cover, with the screen facing the front cover. Press the sealing gasket against the edge of the phone or tablet and between the back cover and the front cover. Align and fasten the front cover onto the back cover, ensuring the sealing gasket is pressed between the front and back covers and between the edge of the phone or tablet and the front cover. Tighten the front and back covers with screws to secure them. This achieves the function of waterproofing the phone or tablet, with only the screen exposed while the rest is sealed inside the mold. The phone or tablet is sealed from all sides, preventing water from entering during polishing.
