Description

A graphics card protection device

technical field

The utility model relates to the field of display technology, in particular to a graphics card protection device.

Background technique

The existing lighting console is provided with multiple display screens, correspondingly provided with multiple graphics cards. However, multiple graphics cards are assembled directly on the motherboard, which is easy to loosen during use or transportation, and poor contact between the graphics card and the motherboard occurs, resulting in no output from the graphics card and frequent repairs and maintenance.

Contents of the invention

The purpose of the invention of the utility model is to overcome the defects of the prior art and provide a graphics card protection device, which can effectively fix the graphics card and prevent the graphics card from loosening or even being damaged during the handling of the host.

In order to achieve the purpose of the above invention, the utility model adopts the following technical solutions: a graphics card protection device, including a motherboard fixing plate, a motherboard arranged on the motherboard fixing plate, a graphics card arranged on the motherboard, and a graphics card support plate connected to the graphics card, its It is characterized in that the graphics card protection device includes a column arranged on the main board fixing plate, and a clamping mechanism arranged on the upper end of the column to limit the graphics card, and the graphics card is tightened by the clamping mechanism to prevent the graphics card from loosening.

Specifically, the clamping mechanism includes a pressure plate, a limit pressure block and a spring. The pressure plate is fixedly connected to the column, the lower end of the limit pressure block is against the graphics card, and the upper end of the limit pressure block is covered with a spring. The upper end of the spring abuts against the pressure plate and is in a compressed state.

Further, the lower end of the limiting pressure block is provided with a card slot adapted to the edge of the graphics card, and the card slot is sleeved on the graphics card.

Further, it also includes a spring pressing plate; the pressing plate is located above the graphics card and has a notch, the spring pressing plate is fixed at the notch, and the spring pressing plate is provided with a through hole equal to the limit pressing block, so A bolt is arranged in the said through hole, and the bolt is threadedly connected with the limit pressure block, and a spring pressure plate is arranged to facilitate installation and maintenance of the limit pressure block.

Further, it also includes a spring limiting plate, the spring pressing plate is fixedly connected with the spring pressing plate through a spacer column, the spring limiting plate is provided with a guide hole equal to the limiting pressing block, and the limiting pressing block is set in the guide hole.

Further, the clamping mechanism also includes a spacer column for auxiliary position limitation, one end of the spacer column is connected to the pressure plate, and the other end is connected to the support plate of the graphics card.

The beneficial effects of the utility model: due to the increased protection of the graphics card device, poor contact damage to the graphics card during transportation, handling or use is avoided, and the possibility of after-sales maintenance in the later period is reduced.

detailed description

Below in conjunction with accompanying drawing, describe the utility model in detail.

With reference to Fig. 1, shown in Fig. 2, a kind of graphics card protective device of the present invention comprises mainboard fixing plate 2, the mainboard 13 that is arranged on the mainboard fixing plate 2, the graphics card 14 that is arranged on the mainboard 13, the front end of graphics card 14 A graphics card supporting board 3 is provided. Four uprights 8 and a clamping mechanism arranged on the uprights 8 are arranged on the main board fixing plate 2 .

Specifically, the clamping mechanism includes a pressure plate 1, a spring pressure plate 4, a limit pressure block 7, a spring limit plate 5, a spacer column 9 and a spring 6, wherein the pressure plate 1 is fixedly connected to the column 8 through screws; the pressure plate 1 is facing the graphics card 14 is provided with a square notch, the spring pressure plate 4 is arranged on the square notch and fixed on the pressure plate 1 by screws, the spring limit plate 5 and the spacer column 9 are fixedly connected by screws; the other end of the spacer column 9 is connected to the spring pressure plate 4 Through screw fixed connection, the spacer column 9 can limit the maximum stroke of the limit pressing block 7 to avoid over-tightening. The spring limiting plate 5 is provided with a guide hole, and the limiting pressing block 7 is installed in the guiding hole. The guiding hole provides a directional movement path for the limiting pressing block 7, and the spring pressing plate 4 is combined with the guiding spring limiting plate 5. After getting up, the movement direction path of the limit pressing block 7 is limited, and the limit pressing block 7 is pressed against the graphics card 14 under the downward force of the spring 6 to prevent the limit pressing block 7 from being biased in a certain direction during the vibration process and being damaged. Graphics card or can not limit the graphics card. The lower end of the limit pressure block 7 is against the graphics card 14, and the upper end of the limit pressure block 7 is provided with a spring 6, and the upper end of the spring 6 is against the spring pressure plate 4 and is in a compressed state. In a more preferred manner of the present invention, the lower end of the limiting pressure block 7 is provided with a card slot adapted to the edge of the graphics card 14 , and the card slot is sleeved on the graphics card 14 .

The front end of graphics card 14 is connected with graphics card support plate 3, and the two ends of limit spacing column 10 are connected with graphics card support plate 3 and pressing plate 1 by screw respectively, increases and sets a fixed point, further limits the position of graphics card, prevents graphics card 2 from loosening.
