[0025] A metal bracket-type mobile phone protective case includes a first protective frame 1, a second protective frame 2 and a connecting member 3. The first protective frame 1 is connected to the connecting member 3. The top of the first protective frame 1 is provided with a first wrapping portion 4 for wrapping the upper corners of the mobile phone. The bottom of the second protective frame 2 is provided with a second wrapping portion 5 for wrapping the lower corners of the mobile phone. The connecting member 3 includes a bottom plate 6, an annular mounting member 7 is provided on the bottom plate 6, a connecting block 8 and a locking groove 9 are provided at the bottom of the annular mounting member 7, a first spring 10 is provided on the connecting block 8, a first mounting groove 11 and a positioning groove 12 are provided in the middle of the second protective frame 2. The connecting block 8 and the positioning groove 12 are arranged in correspondence with each other, and a positioning column 13, a through hole 14 and a transverse groove 15 are provided in the first installation groove 11. A lock core mechanism 16 is provided in the first installation groove 11, and the lock core mechanism 16 includes a sliding key 17 and a lock tongue 18. The lock tongue 18 and the lock groove 9 are arranged in correspondence with each other. The middle part of the lock core mechanism 16 is rotatably connected to the positioning column 13, and the sliding key 17 passes through the through hole 14. A second spring 19 is provided in the transverse groove 15, and one end of the second spring 19 is connected to the bottom of the transverse groove 15, and the other end of the second spring 19 is connected to the side of the lock core mechanism 16.

[0026] Specifically, such as Figure 1-7When the user needs to install and use it, the first wrapping part 4 of the first protective frame 1 is sleeved on the upper corner of the mobile phone, the first protective frame 1 is connected to the connecting member 3, and the positioning groove 12 of the second protective frame 2 is docked with the connecting block 8 of the annular mounting member 7. The connecting block 8 plays a positioning role, and then the user drags the sliding key 17 on the lock core mechanism 16 so that the sliding key 17 slides in the through hole 14. During the sliding process of the sliding key 17, the lock core mechanism 16 rotates along the positioning column 13, and the second spring 19 is squeezed and contracted by the force, so that the lock tongue 18 on the lock core mechanism 16 cannot contact the lock groove 9, and the second protective frame 2 is pushed into the inner part of the connecting member 3. The first spring 10 is compressed, the sliding key 17 is released, the second spring 19 is reset, and the lock tongue 18 on the lock core mechanism 16 cooperates with the lock groove 9 to lock the second protective frame 2 and the connecting member 3; when the user needs to disassemble, he drags the sliding key 17 on the lock core mechanism 16 to disengage the lock tongue 18 on the lock core mechanism 16 from the lock groove 9, the first spring 10 is reset, and the second protective frame 2 is ejected. The mobile phone case can be disassembled by pulling out the second protective frame 2. Compared with the traditional mobile phone case with a metal frame that needs to remove screws, the present invention can be installed and disassembled without the aid of external tools, and the operation is simple, convenient and efficient.

[0027] Furthermore, the first wrapping portion 4 and the second wrapping portion 5 are both provided with mounting holes 20, and rubber pads 21 are provided in the mounting holes 20. The rubber pads 21 are made of soft material and can play a better cushioning role when the mobile phone falls, effectively protecting the mobile phone.

[0028] Furthermore, a rotating ring 22 is rotatably connected to the inner side of the annular mounting member 7, and a rotating bracket 23 is provided on the rotating ring 22. The rotating bracket 23 is connected to the rotating ring 22 by a hinge 24. When the user needs to stand the phone upright, the phone can be stood upright by opening the rotating bracket 23. Since the rotating ring 22 is rotatably connected to the annular mounting member 7, the user can rotate the rotating bracket 23 to stand the phone upright regardless of whether the phone is placed horizontally or vertically.

[0029] Furthermore, a second mounting groove 25 is provided in the middle of the first protective frame 1, a third spring 26 is provided in the second mounting groove 25, the bottom of the second spring 19 is connected to the bottom of the second mounting groove 25, a bump 27 is provided on the top of the third spring 26, the side wall of the bump 27 is slidably connected to the second mounting groove 25, and a plurality of grooves 28 that cooperate with the bumps 27 are arranged at equal intervals on the rotating ring 22. During the rotation of the rotating ring 22, through the cooperation between the bumps 27 and the grooves 28, under the action of the third spring 26, the bumps 27 reciprocate in the second mounting groove 25, increasing the damping of the rotation of the rotating ring 22. The rotating ring 22 stops moving and requires a certain amount of force to rotate the rotating ring 22, ensuring that the mobile phone is not easy to fall when it is erected.

[0030] Furthermore, an arcuate groove 29 is provided on the rotating bracket 23. The arcuate groove 29 is provided to facilitate the user to open the rotating bracket 23, and when the rotating bracket 23 is supported, the arcuate groove 29 serves as a bottom support and is not prone to falling.

[0031] Furthermore, a first opening 30 having the same size as the phone camera is opened in the middle of the first protective frame 1, and a second opening 31 having the same size as the speaker and the charging port is opened on the second protective frame 2. The structure is more reasonable and convenient for users to use the phone.

[0032] Furthermore, the corners of the first protection frame 1, the second protection frame 2 and the connecting frame are all provided with rounded corners, which can prevent the user's skin from being scratched during use.

[0033] Although the present invention has been described above with reference to various embodiments, it will be understood that many changes and modifications may be made without departing from the scope of the present invention. That is, the methods, systems, and devices discussed above are examples. Various configurations may omit, replace, or add various processes or components as appropriate.
