[0027] The utility model is further described in combination with specific embodiments and drawings.

[0028] See Figures 1 to 7As shown, this utility model is a metal frame mobile phone protective case, including: a frame 1 and a base plate 2. The frame 1 is made of metal materials such as aluminum alloy, and the base plate 2 can be made of metal sheet or other rigid plastic materials. The frame 1 is formed by continuous and uninterrupted borders 11 to form a shape corresponding to the shape of the mobile phone. The frame 1 and the base plate 2 are combined to form a cavity for accommodating the mobile phone.

[0029] Combination Figure 3 As shown, the inner edge of the bottom surface of the frame 11 is formed with a stepped platform 10 for supporting the base plate 2. During installation, the base plate 2 is placed on the stepped platform 10, which provides support and positioning for the base plate 2. Slots 12 and connecting slots 13 are respectively provided on opposite sides of the frame 11 (in this embodiment, the top and bottom sides, i.e., the shorter sides). Among these, combined with... Figure 6 As shown, the card slot 12 is located on the stepped platform 10, and the card slot 12 is opened horizontally in the horizontal direction. The side of the frame 11 is also provided with a side hole 131 that communicates with the connecting slot 13.

[0030] The frame 11 is positioned opposite the stepped platform 10 on the other side, that is, a flange 110 is formed extending inward from the surface of the frame 11. The flange 110 is used to limit the position of the mobile phone. When the mobile phone is placed in the cavity of this utility model, the flange 110 limits the edge of the mobile phone and fixes the mobile phone in the protective case.

[0031] The base plate 2 is plate-shaped, and has a plug-in protrusion 21 and a connecting hole 22 on its two opposite sides (the top and bottom sides in this embodiment, i.e., the shorter sides). The plug-in protrusion 21 is adapted to the slot 12 in the frame 11. When the base plate 2 is placed on the stepped platform 10, the plug-in protrusion 12 is inserted into the slot 12 of the frame 11 to achieve a limiting connection on one side of the base plate 2. After the other side is limited and connected to the connecting block 3 through the connecting hole 22, the entire base plate 2 is fixedly connected to the frame 1.

[0032] To ensure accurate positioning between the base plate 2 and the frame 1, a positioning groove 14 is provided along the stepped platform 10 on the frame 11, and a positioning protrusion 23 is formed on the edge of the base plate 2 corresponding to the positioning groove 14. When the base plate 2 is placed on the stepped platform 10, the positioning protrusion 23 and the positioning groove 14 are engaged to ensure accurate positioning between them.

[0033] The connecting block 3 is made of metal; to ensure its strength, steel or steel alloy is preferred. Figure 5As shown, the connecting block 3 includes an integrally formed connecting part 31 and a snap-fit ​​part 32. A bending part 33 is formed between the connecting part 31 and the snap-fit ​​part 32, and the bending part 33 causes the connecting part 31 and the snap-fit ​​part 32 to be offset in position.

[0034] The connecting groove 13 on the frame 3 is used to position and install the connecting block 3. The connecting groove 13 is opened vertically downward along the stepped platform 10, and the thickness of the connecting groove 13 is approximately the same as the thickness of the connecting part 31, so that the connecting part 31 of the connecting block 3 can be placed in the connecting groove 13. After installation, the top surface of the connecting block 3 is flush with the stepped platform 10.

[0035] A notch 132 corresponding to the insert part 32 is provided on the inner side of the connecting groove 13. Because the connecting block 3 causes the connecting part 31 and the insert part 32 to be offset by the bending part 33, the insert part 32 cannot be directly placed in the connecting groove 13. Therefore, the notch 132 accommodates the insert part 32, and simultaneously, the insert part 32 is inserted into the notch 132. This not only positions the connecting block 3, but also, because the insert part 32 is offset relative to the connecting part 31, it is more inclined towards the inner side of the frame 11. Consequently, the position of the connecting hole 22 on the base plate 2 is also more inclined inward, ensuring that the connecting hole 22 is at a sufficient distance from the edge, improving the strength of the connecting hole 22, and preventing insufficient material strength due to the connecting hole 22 being too close to the edge in subsequent threaded connections, further improving the stability of the connection.

[0036] The connecting part 31 has a first threaded hole 34 on its side, which is adapted to the side hole 131 on the frame 11. After the first screw 4 passes through the measuring and controlling 131 on the side, it is threadedly connected to the first threaded hole 34.

[0037] The top surface of the snap-fit ​​part 32 is provided with a second threaded hole 35, which is adapted to the connecting hole 22 on the base plate 2. The second screw (not shown in the figure) passes through the connecting hole 22 from top to bottom and is threaded into the second threaded hole 35.

[0038] To further enhance connection stability, a positioning pin 36 is provided on the top surface of the locking part 32; a pin hole 24 is provided on the base plate 2 corresponding to the position of the positioning pin 36. Specifically, the positioning pin 36 is located beside the second threaded hole 35, and there are two positioning pins 36, located on both sides of the second threaded hole 35. Correspondingly, pin holes 24 are provided on both sides of the connecting hole 22 on the base plate 2.

[0039] When installing this utility model, firstly, the frame 1 is placed on a flat surface, with the side with the flange 110 facing down, and the mobile phone is placed in the area enclosed by the frame 11.

[0040] Next, insert the insertion protrusion 21 of the base plate 2 into the slot 12 of the frame 11, and then place the entire base plate 2 on the stepped platform 10. At the same time, the positioning protrusion 23 on the base plate 2 is engaged with the positioning slot 14 on the frame 11 to ensure accurate positioning between the frame 1 and the base plate 2. Meanwhile, the first screw 4 is passed through the side hole 131 and the first threaded hole 34 to fix the connecting block 3 in the connecting slot 13.

[0041] Finally, the pin hole 24 on the base plate 2 and the positioning pin 36 on the connecting block 3 are used for pin hole positioning. Then, the second screw is passed through the connecting hole 22 and connected to the second threaded hole 35. At this point, the assembly of the mobile phone case and the mobile phone is completed.

[0042] This invention directly uses screws to fix the frame 1 and the base plate together, eliminating the need for springs, hooks, and other components found in existing technologies, thus reducing product costs. Furthermore, this invention connects the frame and base plate via a connecting block, enabling a detachable connection between the two. This not only allows for the installation of the mobile phone but also avoids potential issues such as insufficient material strength and easy damage in the connection between the frame and base plate bracket, improving the stability of the connection.

[0043] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
