[0026] The dustproof mechanism 8 includes a fixed block 801, one side of the fixed block 801 is fixedly connected to a guide rail 802, one end of the guide rail 802 is fixedly connected to an end plate 803, the surface of the guide rail 802 is slidably connected to a slider 804, the inner cavity of the slider 804 is slidably connected to a pull rod 805, one end of the pull rod 805 is fixedly connected to a dustproof block 806, the outer wall of the dustproof block 806 is plugged into the inner wall of the plug-in slot 7, one end of the pull rod 805 is fixedly connected to a limit plate 807, one side of the limit plate 807 is fixedly connected to a pull plate 808, and the computer board adapter is mainly supported by the mounting seat 1. The adapter circuit board 2 and the function board 3 are integrated and installed inside the chassis. The adapter circuit board 2 and the function board 3 on the inner wall of the mounting seat 1 are shielded and protected by the mounting plate 6 and can be fixed to the chassis. One side of the adapter circuit board 2 and the function board 3 is fixedly connected with a plug-in board, which can be connected to the adapter seat on the inner wall of the mounting seat 1. The plug-in board on the other side of the adapter circuit board 2 and the function board 3 can be plugged into the motherboard of the computer. The function board 3 has a device interface 301, so that the plug-in port of the function board 3 corresponds to the plug-in slot 7 after the installation of the mounting seat 1, which is convenient for the connection of external devices.

[0027] In addition, when the device interface 301 is not connected to an external device, the dust block 806 is plugged into the plug-in slot 7 for sealing, and the position of the pull rod 805 is limited by the limit plate 807. When plugging in an external device, the dust block 806 is pulled out of the plug-in slot 7 by the pull plate 808. The dust block 806 is stored in the inner wall of the slider 804. The slider 804 can slide along the surface of the guide rail 802 to make the plug-in slot 7 leak out, which is convenient for plugging in an external device. Therefore, the computer's board adapter can seal and protect the socket when no external device is connected, thereby improving the dustproofness of the port and extending the service life of the board.

Through the set adaptive spring buckle 9, when the dustproof block 806 is pulled out from the inner wall of the plug-in slot 7 and stored in the slider 804, the spring 10 releases the elastic potential energy to pop out the adaptive spring buckle 9 and plug it into the limiting groove 11, so as to avoid the dustproof block 806 from shaking. The contact surfaces of the adaptive spring buckle 9 and the limiting groove 11 are both arranged in an arc shape, so that the dustproof block 806 will not be blocked by the adaptive spring buckle 9 when it is displaced, and the cooperation of the adaptive spring buckle 9 and the spring 10 can improve the firmness of the plug-in of the dustproof block 806 and the plug-in slot 7.

When the plug-in slot 7 is in use, the metal sheet 13 and the magnetic block 12 of the end plate 803 are mutually adsorbed to limit the position of the slider 804 that slides away from the plug-in slot 7.

[0031] Reference Figure 4 and Figure 5 A side plate 14 is fixedly connected to one side of the mounting seat 1. The number of the side plates 14 is two. A slide groove 15 is provided on one side of the two side plates 14. A pressure plate 16 is slidably connected to the inner wall of the slide groove 15. One side of the pressure plate 16 fits the adapter circuit board 2. A threaded rod 17 is rotatably connected to the inner wall of the slide groove 15.

Through the setting of the pressure plate 16, the threaded rod 17 can be driven to rotate through the adjusting handle 18. Since the inner cavity of the pressure plate 16 is threadedly connected to the surface of the threaded rod 17, the rotation of the threaded rod 17 can drive the pressure plate 16 to slide along the slide groove 15, approaching until it fits the adapter circuit board 2, thereby ensuring the stability of the installation and power supply of the adapter circuit board 2. Through the setting of the guide rod 19, when the pressure plate 16 slides along the inner wall of the slide groove 15, the inner cavity slides along the surface of the guide rod 19, thereby further improving the stability of the connection and displacement of the pressure plate 16.

The connection firmness between the mounting seat 1 and the chassis can be improved, while ensuring the stability of the connection between the adapter circuit board 2 and the computer motherboard.

[0033] Working principle: the positioning hole 5 on the adapter circuit board 2 is first connected to the positioning column 4, and then the positioning hole 5 on the function board 3 is connected to the positioning column 4. The threaded rod 17 can be driven to rotate by the adjusting handle 18. Since the inner cavity of the pressure plate 16 is threadedly connected to the surface of the threaded rod 17, the pressure plate 16 can be driven to slide along the slide groove 15 while the threaded rod 17 rotates, approaching until it fits the adapter circuit board 2, ensuring the stability of the installation and power supply of the adapter circuit board 2, and integrating the adapter circuit board 2 and the function board 3 into one body and installing them inside the chassis. The adapter circuit board 2 and the function board 3 on the inner wall of the mounting seat 1 are shielded and protected by the mounting plate 6 and can be fixed to the chassis. One side of the adapter circuit board 2 and the function board 3 is fixedly connected with a plug-in board, which can be connected to the adapter seat on the inner wall of the mounting seat 1. The adapter circuit board 2 and The plug-in board on the other side of the function board 3 can be plugged into the motherboard of the computer. The function board 3 has its own device interface 301, so that the plug-in port of the function board 3 corresponds to the plug-in slot 7 after the function board 3 is installed on the mounting seat 1, which is convenient for connecting external devices. When the device interface 301 is not connected to the external device, the dust block 806 is plugged into the plug-in slot 7 for sealing, and the position of the pull rod 805 is limited by the limit plate 807. When plugging in an external device, the dust block 806 is pulled out of the plug-in slot 7 by the pull plate 808, and the dust block 806 is stored in the inner wall of the slider 804. The slider 804 can slide along the surface of the guide rail 802 to make the plug-in slot 7 leak out, which is convenient for plugging in external devices. Therefore, the board adapter of the computer can seal and protect the socket when no external device is connected, thereby improving the dustproofness of the port and extending the service life of the board.
