[0030] In the prior art, the screen and the mobile phone case are fixed together by a series of connectors and screws. In addition, glue or other adhesives are used to ensure a stable connection between the screen and the mobile phone case. Therefore, when disassembling the mobile phone screen, some disassembly tools are needed to unscrew the screws, and the glue on the mobile phone screen must be cleaned after disassembly to avoid affecting the subsequent installation of the mobile phone screen. The operation is relatively cumbersome. In view of this, a screen card structure and a mobile phone screen are proposed. Therefore, after research, a screen card structure and a mobile phone screen are provided. When in use, the plug-in board is inserted into the positioning hole, and the wedge block is inserted into the slot, and then the plug-in board is fixed in the positioning hole, so that the screen assembly is installed on the rear shell. At the same time, the plug-in cooperation with the positioning slot is used to further improve the stability of the installation of the screen assembly. Then, the installation frame is installed in the rear shell, so that the screen assembly is stably fixed, eliminating the use of screws, thereby solving the above defects.

[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Please refer to Figures 1 to 9 The embodiment of the utility model provides a screen card-mounting structure and a mobile phone screen, including a screen assembly 1 and a rear shell 2, an inner plate 11 is arranged on the back of the screen assembly 1, plug-in plates 12 are arranged on both sides of the inner plate 11, and a mounting frame 6 is connected inside the rear shell 2, wherein first dovetail grooves 66 are symmetrically opened on the outer walls on both sides of the mounting frame 6, and positioning blocks 21 are symmetrically arranged on the inner wall of the rear shell 2, so that the positioning blocks 21 are card-fitted with the first dovetail grooves 66, and the mounting frame 6 can be installed inside the rear shell 2.

[0033] At the same time, positioning holes 61 are symmetrically opened on both sides of the upper end of the installation frame 6 . When the plug-in board 12 is plugged into the positioning hole 61 , the screen assembly 1 is installed on the rear shell 2 .

[0034] In order to enhance the stability of the mounting frame 6 in the rear shell 2, second dovetail grooves 67 are opened on the other two sides of the mounting frame 6, and plug blocks 22 are provided on the inner walls of the other two sides of the rear shell 2. The plug blocks 22 are inserted into the second dovetail grooves 67 to enhance the tightness of the connection between the mounting frame 6 and the rear shell 2.

[0035] In addition, sliding holes 23 are provided on both sides of the plug block 22, and special-shaped blocks 25 are slidably arranged in the sliding holes 23. The special-shaped blocks 25 are plugged into the inner groove 68 provided on the inner side of the second dovetail groove 67. At the same time, a first spring 24 is provided in the sliding hole 23, and one end of the first spring 24 is connected to the special-shaped block 25. When the installation skeleton 6 enters the rear shell 2, the inner walls on both sides of the second dovetail groove 67 squeeze the special-shaped blocks 25, so that the special-shaped blocks 25 squeeze the first spring 24 and slide into the sliding hole 23. When the special-shaped block 25 encounters the inner groove 68, the first spring 24 loses its force, prompting the special-shaped block 25 to slide into the inner groove 68, thereby strengthening the fixing effect of the plug block 22.

[0036] In order to improve the stability of the connection between the screen assembly 1 and the mounting frame 6, positioning grooves 62 are opened on the mounting frame 6 on both sides of the positioning hole 61, and insertion rods 13 are set on both sides of the insertion board 12. When the insertion board 12 is inserted into the positioning hole 61, the insertion rod 13 is plugged into and matched with the positioning groove 62.

[0037] A straight groove 63 is provided on one side of the positioning hole 61, and a wedge block 64 is slidably provided in the straight groove 63. The wedge block 64 is plugged into the slot 14 provided on one side of the plug board 12. At the same time, a second spring 65 is provided in the straight groove 63, and one end of the second spring 65 is connected to the wedge block 64. When the plug board 12 moves downward, the wedge block 64 is pushed inward, so that the wedge block 64 squeezes the second spring 65 and slides into the straight groove 63. When the slot 14 moves to one side of the wedge block 64, the second spring 65 loses its force, prompting the wedge block 64 to be plugged into the slot 14 to fix the plug board 12.

[0038] In order to facilitate the disassembly of the screen assembly 1, a through groove 69 is opened on the lower side of the positioning hole 61, and the slide plate arranged on the lower side of the wedge block 64 passes through the through groove 69 and extends to the outside. The slide plate is slidably connected to the through groove 69, and the slide plate slides with the wedge block 64 to one side of the through groove 69, so that the wedge block 64 can slide into the straight groove 63, so that the wedge block 64 is separated from the slot 14, and the wedge block 64 can be taken out.

[0039] On the other hand, the present application also provides a mobile phone screen with a screen card-mounted structure, the screen assembly 1 includes an outer screen glass 3, a touch panel 4 is arranged on the inner side of the screen glass 3, a polarizing plate 5 is arranged on the lower side of the touch panel 4, and a display panel 51 is arranged on the lower side of the polarizing plate 5.

[0040] In summary, the working principle of a screen card-mounting structure and a mobile phone screen in an embodiment of the utility model is as follows: the plug-in board 12 is inserted into the positioning hole 61, and the wedge block 64 is inserted into the slot 14, and then the plug-in board 12 is fixed in the positioning hole 61, so that the screen assembly 1 is installed on the rear shell 2, and at the same time, the plug-in cooperation of the plug-in rod 13 and the positioning groove 62 is used to further improve the installation stability of the screen assembly 1, and then the installation frame 6 is installed in the rear shell 2 through the cooperation of the first dovetail groove 66 and the positioning block 21, and the second dovetail groove 67 and the plug-in block 22, so that the screen assembly 1 is card-mounted on the upper side of the rear shell 2, and then the installation frame 6 is taken out from the rear shell 2, and the slide plate on the lower side of the wedge block 64 is slid, so that the wedge block 64 squeezes the second spring 65 to slide into the straight groove 63, and then the plug-in board 12 is disengaged from the positioning hole 61, so as to facilitate the disassembly of the screen assembly 1.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
