The corresponding baffle 6 is moved to expose the video card interface 4, and then the data cable is connected to use the video card body 1. A toggle plate 7 is fixed on the front side of the baffle 6 near the bottom. A sealing component 8 is provided in the sealing groove 5 for pushing the baffle 6 for sealing. Multiple video card interfaces 4 are independently opened in the slot 3, and each slot 3 is also independently opened. In this way, the unused video card interface 4 will be sealed by the sealing component 8 through the baffle 6, avoiding dust from adhering to the video card interface 4, which makes it difficult to clean the dust and affects the use when the user needs to replace other video card interfaces 4. It is more practical.

[0022] It should be noted that the video card body 1 is mainly composed of a circuit board, a chip and other electronic components. The structure, usage method and working principle of the video card body 1 are a mature and public technology in the prior art. This technology is relatively common in the market. Therefore, the structure, usage method and working principle of the video card body 1 will not be repeated in this article.

[0023] The sealing assembly 8 includes a first telescopic rod 801 fixed on the top wall of the sealing groove 5, a contact plate 802 is fixed to the bottom end of the first telescopic rod 801, and a first spring 803 is mounted on the outer peripheral wall of the first telescopic rod 801. After selecting the corresponding interface type, the baffle 6 is pushed upward by the toggle plate 7, and the baffle 6 moves upward to abut against the abutment plate 802 and push the abutment plate 802 to move upward. The abutment plate 802 moves upward to shrink the first telescopic rod 801 and compress the first spring 803, so that when the data cable is pulled out, the baffle 6 can be pushed to return to its original position to block the slot 3 for sealing. Two circular grooves 804 connected to the sealing groove 5 are provided in the panel 2 and at the rear of the sealing groove 5. A second telescopic rod 805 is fixed to the inner wall of the back of the circular groove 804. Two slide grooves 806 are provided on the back of the baffle 6. A slider 807 is slidably connected in the slide groove 806. The two sliders 807 The back side is distributed and fixed on the front end of the two second telescopic rods 805, and the outer peripheral wall of the second telescopic rods 805 is covered with a second spring 808. Two connecting plates 809 distributed up and down are fixed on the left and right sides of the baffle 6, and abutment wheels 810 are fixed on the front of the connecting plates 809. Four wheel grooves 811 are opened in the panel 2 and on the front side of the sealing groove 5. An annular sealing gasket 812 is fixed on the front side of the baffle 6. When the baffle 6 is pushed to move upward, the abutment wheel 810 will be disengaged from the wheel groove 811. At this time, the baffle 6 will move backward a short distance while moving upward, so that the annular sealing gasket 812 will be disengaged from the inner wall of the front side of the sealing groove 5, so as to facilitate the pushing of the baffle 6 to move upward. When the baffle 6 moves backward, the second spring 808 will be squeezed, so as to push the baffle 6 forward when it moves down and resets, thereby making the annular sealing gasket 812 fit with the inner wall of the front side of the sealing groove 5 to increase the airtightness and dustproofness.

[0024] In this embodiment, the sealing groove 5 is connected to the slot 3 in a cross shape, and the front area of ​​the baffle 6 is larger than the front area of ​​the slot 3. Such a structure makes it easy to block the slot 3 through the baffle 6 to form a sealed space to prevent dust from adhering to the video card interface 4 and causing inconvenience.

[0025] The sealing groove 5 is used for the baffle 6 to slide up and down inside it. The abutment plate 802 is slidably connected to the sealing groove 5 and is gap-matched therewith. The abutment plate 802 is located directly above the baffle 6 and abuts against the top surface of the baffle 6. Such a structure makes it easy for the baffle 6 to squeeze the first spring 803 when it moves upward, so that when the video card interface 4 is not in use, the elastic potential energy of the first spring 803 can push the baffle 6 to block the slot 3.

[0026] The two circular grooves 804 are respectively located on the left and right sides of the slot 3 and close to the inner top wall of the slot 3 . The slide groove 806 is used for the slider 807 to slide up and down.

[0027] The four connecting plates 809 are respectively close to the four corners of the baffle 6 , and the four wheel grooves 811 are respectively opposite to the four connecting plates 809 in front and back.

[0028] The wheel groove 811 is a conical groove, and the distance between the front and rear sides of the inner wall of the wheel groove 811 is greater than the distance from the front of the abutment wheel 810 to the front of the baffle 6. In this way, when the baffle 6 moves upward, the abutment wheel 810 pushes the baffle 6 to move backward a certain distance, thereby avoiding the inner wall of the sealing groove 5 from damaging the annular sealing gasket 812 during the upward movement. At the same time, such a structure can enable the annular sealing gasket 812 to better fit and seal with the sealing groove 5 when the baffle 6 blocks the slot 3, thereby increasing the dustproof sealing effect.

[0029] The working principle of the above embodiment is:

[0030] When in use, select the corresponding interface type, and then push the baffle 6 upward by the toggle plate 7. The baffle 6 moves upward to abut against the abutment plate 802 and push the abutment plate 802 upward. The abutment plate 802 moves upward to cause the first telescopic rod 801 to contract and compress the first spring 803, so that when the data cable is pulled out, the baffle 6 can be pushed to reset and block the slot 3 for sealing. When the baffle 6 is pushed upward, the abutment wheel 810 will be disengaged from the wheel groove 811. At this time, the baffle 6 will move backward a short distance while moving upward, so that the annular sealing gasket 812 will be disengaged from the inner wall of the front side of the sealing groove 5, so as to facilitate the push of the baffle 6 to move upward. When the baffle 6 moves backward, it will squeeze the second spring 808, so as to push it forward when the baffle 6 moves downward and resets, thereby making the annular sealing gasket 812 fit with the inner wall of the front side of the sealing groove 5 to increase the airtightness and dustproofness.
