[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figure 1 This utility model provides a computer graphics card testing fixture 100, including a frame 10, a plug-in assembly 20 and an ejection assembly 30. The frame 10 is provided with a carrier plate 11 and a test motherboard 12. The carrier plate 11 is used to place the computer graphics card, and the test motherboard 12 is used to plug in the computer graphics card. The carrier plate 11 is connected to a moving cylinder 3 113. The output end of the moving cylinder 3 113 is connected to the carrier plate 11. The moving cylinder 3 113 is used to drive the carrier plate 11 to move to plug in with the test motherboard 12.

[0029] Please refer to Figure 4 , Figure 5 and Figure 6 The plug-in assembly 20 includes a moving cylinder 21 and a carrier 22 connected to the output end of the moving cylinder 21. An interface 23 is connected to the carrier 22, and an interface 24 is plugged into the interface 23. The moving cylinder 21 is used to drive the interface 24 to move to connect with the computer graphics card.

[0030] Specifically, Interface 1 (23) is a standard interface, compatible with Interface 2 (24) in standard DP, HDMI, or USB-C form factors. During testing, Interface 1 (23) is electrically connected to the monitor, and Interface 2 (24) is plugged into the computer's graphics card. The detachable connection of Interface 1 (23) and Interface 2 (24) allows for easy replacement of Interface 2 (24) depending on the type of Interface 2 (24) required by the computer's graphics card.

[0031] Please refer to Figure 5 and Figure 6 The plug-in assembly 20 also includes a second carrier 25 connected to the first carrier 22. The second interface 24 is connected to a connecting frame 241. A connecting screw 251 is connected to the second carrier 25, and a spring 252 is fitted onto the connecting screw 251. The connecting frame 241 has a connecting hole 2411 corresponding to the connecting screw 251, and the connecting screw 251 passes through the connecting hole 2411. The second interface 24 and the second carrier 25 are floatingly connected by the spring 252 and the connecting screw 251. Specifically, the second carrier 25 has a through-hole 253 for the second interface 24 to pass through.

[0032] By connecting the screw 251 and the spring 252, when the moving cylinder 21 drives the interface 24 to move to the position where it is plugged into the computer graphics card, the elastic force generated by the compression of the spring 252 cancels out the plugging force, causing the interface 24 to float relative to the carrier 25, and thus float relative to the computer graphics card for plugging, thereby reducing the possibility of damage to the interface 24 due to excessive plugging force.

[0033] To guide you through connecting interface 24 and the computer's graphics card, please refer to... Figure 2 The carrier plate 11 is provided with a guide plate 114, and the guide plate 114 is provided with a guide groove 1141 corresponding to the interface 24. The guide plate 114 is provided to facilitate the guidance when the interface 24 and the computer graphics card are plugged in, thereby improving the plugging accuracy of the interface 24.

[0034] Please refer to Figure 2 and Figure 7 The ejection assembly 30 includes a locking cylinder 31, a positioning post 32, and a compression spring 33 sleeved on the positioning post 32. An ejection rod 331 is connected to the compression spring 33. The output end of the locking cylinder 31 is connected to a locking rod 311 corresponding to the ejection rod 331. When the computer graphics card is placed on the carrier plate 11, the computer graphics card presses on the ejection rod 331, the compression spring 33 is compressed, and the locking cylinder 31 drives the locking rod 311 to move to fix the ejection rod 331.

[0035] By using a locking cylinder 31, an ejector rod 331, and a compression spring 33, when placing a computer graphics card, the graphics card pushes the ejector rod 331 to move, which in turn compresses the compression spring 33. After the graphics card is in place, the locking cylinder 31 drives the locking rod 311 to move and fix the ejector rod 331. However, when the computer graphics card needs to be removed after testing, the locking cylinder 31 drives the locking rod 311 to move and release the fixation of the ejector rod 331. The compression spring 33 returns to its original position, which in turn pushes the ejector rod 331 to raise the graphics card. The edge of the graphics card can be raised to facilitate the worker's access, thus improving unloading efficiency.

[0036] For details, please refer to Figure 8The positioning post 32 includes a first rod 321 and two second rods 322 connected to the axial ends of the first rod 321. The diameter of the first rod 321 is smaller than the diameter of the second rods 322. The ejector rod 331 and the compression spring 33 are both located on the first rod 321, and one end of the compression spring 33 is fixedly connected to the end face of one of the second rods 322. The end face of the other second rod 322 limits the range of movement of the ejector rod 331 after being subjected to the elastic force of the compression spring 33. This is to prevent the ejector rod 331 from moving too far after being subjected to the elastic force of the compression spring 33 when removing the computer graphics card, thus preventing it from detaching from the first rod 321. It also prevents the ejector rod 331 from moving the computer graphics card too far due to the excessive elastic force of the compression spring 33.

[0037] Please refer to Figure 1 Multiple ejector components 30 are provided. To avoid interference with the test motherboard 12, all ejector components 30 are positioned on the side of the computer graphics card away from the test motherboard 12 in the width direction. After the test is completed, the multiple ejector rods 331, through the elastic force of the compression spring 33, slightly tilt one end of the computer graphics card in the width direction, making it easier for staff to handle. It is understood that the size of the compression spring 33 and the ejector rods 331 in this embodiment is much smaller than the computer graphics card, and the elastic force of the compression spring 33 is only enough to tilt one end of the computer graphics card, without damaging the computer graphics card.

[0038] For further details, please refer to Figure 7 and Figure 8 Both the front ends of the locking lever 311 and the ejector lever 331 are arc-shaped blocks, and their combined shape forms a complete circle. Furthermore, the central angle of the arc-shaped trajectory corresponding to the front end of the locking lever 311 is smaller than the central angle of the arc-shaped trajectory corresponding to the front end of the ejector lever 331. This ensures a larger contact area between the ejector lever 331 and the compression spring 33 when the computer graphics card is placed, facilitating the ejector lever 331 to compress the compression spring 33.

[0039] Please refer to Figure 2 The carrier plate 11 has a slot 111 corresponding to the ejector rod 331. When the computer graphics card is placed on the carrier plate 11, the ejector rod 331 is pressed into the slot 111. Specifically, when the computer graphics card is placed on the carrier plate 11, the ejector rod 331 is inserted into the slot 111, and the top of the ejector rod 331 is flush with the end face of the carrier plate 11. The slot 111 facilitates the positioning of the ejector rod 331.

[0040] Please refer to Figure 8The locking lever 311 is provided with a positioning block 3111, and the ejector lever 331 is provided with a positioning groove 3311 corresponding to the positioning block 3111. The locking cylinder 31 is used to drive the positioning block 3111 to insert into the positioning groove 3311. Through the cooperation of the positioning block 3111 and the positioning groove 3311, it is convenient for the locking cylinder 31 to drive the locking lever 311 to move and fix the ejector lever 331 when the computer graphics card is placed on the carrier board 11.

[0041] Please refer to Figure 2 and Figure 3 The computer graphics card testing fixture 100 also includes a positioning component 40, which includes a positioning cylinder 41 and a positioning plate 42 connected to the output end of the positioning cylinder 41. The positioning cylinder 41 drives the positioning plate 42 to move and press against the side wall of the computer graphics card. The carrier plate 11 has a groove 112 corresponding to the positioning plate 42. During testing of the computer graphics card, the positioning cylinder 41 and the positioning plate 42 limit the movement of the computer graphics card, making it less prone to movement during testing and improving the stability of the computer graphics card test.

[0042] Please refer to Figure 9 The computer graphics card testing fixture 100 also includes an LED testing component 50. The LED testing component 50 includes a second movable cylinder 51 and a probe module 52 connected to the output end of the second movable cylinder 51. The second movable cylinder 51 is used to drive the probe module 52 and connect it to the computer graphics card. Specifically, the probe module 52 is electrically connected to an LED testing instrument. When the second movable cylinder 51 drives the probe module 52 to connect to the computer graphics card, the LED testing instrument uses the probe module 52 to detect whether the logo LED of the computer graphics card is lit and whether the color of the logo LED meets the requirements. The probe module 52 is prior art, and its specific structure will not be described in detail in this utility model.
