[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 6 As shown, the utility model provides a technical solution: a heat dissipation device for a computer graphics card, comprising a protective shell 1, a graphics card inner board 2 is installed inside the protective shell 1, a fan 3 is installed on the surface of the protective shell 1, one end of the fan 3 is fixedly connected to a fin-shaped heat dissipation plate 4, the top of the fin-shaped heat dissipation plate 4 is fixedly connected to a limiting shell 5, the top of the protective shell 1 is fixedly connected to an adjustment shell 6, the inner cavity of the adjustment shell 6 is slidably connected to a connecting block 7, both sides of the connecting block 7 are fixedly connected to a fixing rod 8, the surface of the fixing rod 8 is slidably connected to a sliding plate 9, both sides of the limiting shell 5 are provided with limiting grooves 10, the inner cavity of the limiting groove 10 is slidably connected to a limiting block 11, one end of the limiting block 11 close to the sliding plate 9 is fixedly connected to the sliding plate 9, the top of the connecting block 7 is fixedly connected to a hollow column 12, the inner cavity of the hollow column 12 is slidably connected to a sliding column 13, the top of the adjusting shell 6 is fixedly connected to a limiting plate 14, the top of the limiting plate 14 A slot 15 is provided, and the inner cavity of the slot 15 is slidably connected to the limit rod 16, and the end of the limit rod 16 close to the slide column 13 is fixedly connected to the slide column 13. When the staff needs to improve the heat dissipation efficiency of the graphics card, the staff presses the hollow block 19 inward, so that the hollow block 19 pushes the slide plate 9 to move, and at the same time drives the hollow block 19 to drive the surface of the limit block 11 to gradually separate from the inner cavity of the limit groove 10. At this time, the staff pulls the limit rod 16 upward to separate the surface of the limit rod 16 from the inner cavity of the slot 15, and then the staff pulls the limit rod 16 horizontally to gradually separate the slide plate 9 and the limit block 11 from the inner cavity of the limit shell 5. Through the setting of the above structure, through the installation and fixation of the fin-shaped heat sink 4, the temperature of the surface of the inner plate 2 of the graphics card is conducted to the fin-shaped heat sink 4 through the heat dissipation mud 24, and at the same time, the fin-shaped heat sink 4 discharges the heat through the fan 3, thereby further improving the heat dissipation efficiency of the graphics card.

[0023] Reference Figure 3As shown, in the present embodiment: both sides of the connecting block 7 are fixedly connected with the first spring 17, and one end of the first spring 17 close to the slide 9 is fixedly connected to the slide 9. The staff presses the hollow block 19 to drive the inner cavity of the slide 9 to slide on the surface of the fixed rod 8, and at the same time squeezes the first spring 17 to store force. Through the setting of the first spring 17, the rebound force of the first spring 17 continuously pushes the slide 9 to reset, so that the slide 9 drives the surface of the limit block 11 to engage with the inner cavity of the limit groove 10, thereby completing the installation and fixation of the fin-shaped heat sink 4.

[0024] Reference Figure 3 As shown, in the present embodiment: through grooves 18 are provided on both sides of the adjustment shell 6, and the inner cavity of the through groove 18 is slidably connected with a hollow block 19, and the inner cavity of the hollow block 19 is slidably connected to the surface of the fixed rod 8. The staff pulls the limit rod 16 to drive the hollow column 12 and the connecting block 7 to move, and at the same time, the connecting block 7 drives the fixed rod 8 and the hollow block 19 to move, so that the surface of the hollow block 19 slides in the inner cavity of the through groove 18. Through the arrangement of the above structure, the connecting block 7 maintains directional displacement during displacement, thereby ensuring the stability of the structure.

[0025] Reference Figure 3 and Figure 5 As shown, in this implementation scheme: the inner cavity of the adjusting shell 6 is fixedly connected with the second spring 20, and the end of the second spring 20 close to the connecting block 7 is fixedly connected to the connecting block 7. The staff pulls the limit rod 16 to drive the connecting block 7 to move, and at the same time squeezes the second spring 20 to store force. Through the setting of the above structure, the rebound force of the second spring 20 continuously pushes the connecting block 7 to reset, and at the same time drives the slide 9 and the limit block 11 to reset, thereby further improving the coordination between the structures.

[0026] Reference Figure 5 As shown, in the present embodiment: a first slide groove 21 is opened inside the hollow column 12, and the inner cavity of the first slide groove 21 is slidably connected with a first slider 22, and the end of the first slider 22 close to the slide column 13 is fixedly connected to the slide column 13. The staff pulls the limit rod 16 to drive the slide column 13 to move, and at the same time drives the surface of the first slider 22 to slide in the inner cavity of the first slide groove 21. Through the arrangement of the above-mentioned structure, the slide column 13 remains stable during displacement and does not shake.

[0027] Reference Figure 5 As shown, in this implementation scheme: the top end of the connecting block 7 is fixedly connected with a third spring 23, and the top end of the third spring 23 is fixedly connected to the sliding column 13. The staff pulls the limit rod 16 to drive the sliding column 13 to move, and at the same time the sliding column 13 stretches the third spring 23 to store force. Through the setting of the third spring 23, the rebound force of the third spring 23 continuously stretches the surface of the limit rod 16 and the inner cavity of the slot 15 for continuous clamping.

[0028] Reference Figure 6 As shown, in this embodiment: a heat dissipation mud 24 is installed on the surface of the graphics card inner board 2, and the other end of the heat dissipation mud 24 is fitted with the fin-shaped heat sink 4. Through the setting of the heat dissipation mud 24, the heat dissipation mud 24 has good thermal conductivity, which is convenient for conducting the heat generated by the graphics card inner board 2.

[0029] Working principle: When the staff needs to improve the heat dissipation efficiency of the graphics card, the staff presses the hollow block 19 inward, so that the hollow block 19 pushes the slide 9 to move, and at the same time drives the hollow block 19 to drive the surface of the limit block 11 to gradually separate from the inner cavity of the limit groove 10. At this time, the staff pulls the limit rod 16 upward to separate the surface of the limit rod 16 from the inner cavity of the slot 15. Then the staff pulls the limit rod 16 horizontally to gradually separate the slide 9 and the limit block 11 from the inner cavity of the limit shell 5. Through the setting of the above-mentioned structure, by installing and fixing the fin-shaped heat sink 4, the temperature of the surface of the inner plate 2 of the graphics card is transferred to the fin-shaped heat sink 4 through the heat dissipation mud 24. At the same time, the fin-shaped heat sink 4 discharges the heat through the fan 3, thereby further improving the heat dissipation efficiency of the graphics card.
