[0003] During actual computer assembly or maintenance, affected by factors such as the internal space layout of the chassis, obstruction by other hardware, and limited operating space, it is difficult for users to ensure that the graphics card is inserted and removed at an absolutely vertical and precise angle every time, and tilting during plugging and unplugging occurs frequently. For example, in some compact chassis, the space around the graphics card slot is narrow, and when installing or removing the graphics card, the installer cannot keep the graphics card completely parallel to the slot, and there will often be a certain angle of tilt. Therefore, a tiltable plugging and unplugging test is needed to simulate such common actual operation scenarios and make the test results closer to the performance of the graphics card in the real usage environment; At the same time, during the testing process, the connection lines of the test ports are prone to entanglement and chaos, which not only affects the testing efficiency but also may cause damage to the connection lines or poor contact of the ports due to pulling, interfering with the accuracy of the test results; in addition, the adaptability of existing devices to graphics cards of different sizes is poor, and it is difficult to meet diverse testing requirements. In view of this, we propose a computer graphics card plugging and unplugging testing device and method. Summary of the Invention

The former is efficient and fast, simulating manual unplugging, and the latter realizes multi-angle tilt plug-in and pull-out tests to comprehensively detect the performance of the graphics card.

[0006] Preferably, the testing mechanism also includes a first motor, which is fixedly connected in a hole on the testing platform, and a turntable is drivingly connected to the first motor. A bracket is fixedly connected to the left side of the top of the testing platform, and a support plate is fixedly connected to the inner wall of the bottom of the bracket. The inner walls on both sides of the bracket are symmetrically structured and fixedly connected with sliding rods. The two sliding rods are movably sleeved with a pneumatic frame, and rubber strips are fixedly connected to the two sides of the top of the pneumatic frame in a linear array.

[0007] Preferably, the plug assembly further comprises a cover plate, which is fixedly connected to the top of the push plate, a plurality of first springs are fixedly connected to the inner wall of one side of the push plate in a linear array, and airbags are fixedly connected to the inner walls of both sides of each of the fixing boxes.

[0008] Preferably, the first spring is fixedly connected to the side surface of the waist-shaped hinged plate, wherein the tops of the four fixed boxes are rotatably connected to a slide plate; The first spring applies force to the waist-shaped hinge plate, so that the fixing boxes are arranged in an arc array.

[0009] Preferably, a handle is rotatably connected to the right side of the top of each slide plate. A card slot is provided on the side surface of the handle. Four waist-shaped holes are provided on the top of the cover plate, and the handle passes through the waist-shaped holes. Clamping rings are fixedly connected to the top of the cover plate along the edges of the waist-shaped holes. The card slot is adapted to be buckled with the clamping ring; By buckling or unlocking the card slot with the clamping ring, and the first spring applying a force to the six fixed boxes, the six fixed boxes are caused to have a linear array plugging and unplugging effect or an arc array plugging and unplugging effect.

[0010] Preferably, the winding assembly includes two support cylinders, and the two support cylinders are symmetrically fixedly connected to both sides of the support plate.

[0011] Preferably, a triangular frame is fixedly connected to the inside of each of the two support cylinders. The triangular frame and the inner wall of the support cylinder form three wire threading channels, and a fixed disk is fixedly connected to one side of the triangular frame; By forming three wire threading channels between the triangular frame and the inner wall of the support cylinder, it is possible to prevent the connection wires at the port on the left side of the triangular frame from being wound, resulting in too short a wire length and affecting the movement of the fixed box.

[0012] Preferably, a second motor is fixedly connected to the left side of each triangular frame, a pawl is fixedly connected to the output shaft of the second motor, and the wire winding cylinder is movably sleeved on the surface of the output shaft of the second motor.

[0013] Preferably, the stretching assembly further includes a filling port, and the filling port is arranged on the surface of the fixed disk and is communicated with the sealing cavity.

[0014] A method for using a computer graphics card plugging and unplugging test device includes the following steps: S1. Test preparation and graphics card fixation: First, place the computer graphics card on the top of the support plate, and then through the pneumatic system, move the pneumatic frame downward on the slide rod so that several rubber strips wrap around the surface of the graphics card. Then, install the test port inside the fixed box and fix it with an airbag, and plug it into the graphics card interface. Observe whether it is connected through the test platform, and adjust the lengths of the connecting frame and the push rod by threaded connection to adapt to graphics cards of various sizes; S2. Graphics card plugging and unplugging test; S2.1. Linear array plugging and unplugging test: First, rotate the handle to make the card slot and the clamping ring in a buckled state, so that several fixed boxes are arranged in a linear array. Then, through the external circuit mechanism, make the first motor work to drive the turntable, apply a force to the push rod, and make it reciprocate. Further, make the push plate reciprocate horizontally on the support plate. Among them, the test port is made to shake through the airbag, and an inclined force is applied to it during the pulling-out process to simulate the manual pulling-out effect and achieve an efficient and rapid plugging and unplugging test; S2.2. Arc-arranged insertion and extraction test: Rotate the handle to make the card slot and the snap ring in a non-engaged connection state. Then, apply a force to the waist-shaped hinge plate through the first spring to expand several fixed boxes, forming an arc-shaped array arrangement. During use, by rotating, the driving push plate reciprocally translates on the support plate, causing the test ports arranged in an arc to be inserted into the graphics card connection port. During this process, the test ports are in an inclined state to simulate the insertion effect of the test ports in an inclined state. During the extraction process of the test ports, the test ports at both ends are extracted first and are extracted obliquely through the force applied by the first spring, and the middle test ports are extracted translationally, achieving the insertion and extraction effect at multiple angles. S3. Winding of the connecting wires of the test ports: During the test, the connecting wires pass through the wire threading channels respectively, and then the second motor is driven by an external circuit mechanism to drive the ratchet to rotate. Among them, through the meshing connection of the ratchet and the ratchet teeth, the wire winding cylinder is caused to rotate to helically wind the three connecting wires. When several test ports move to the left, the connecting wires being wound are in a non-meshing sliding connection through the ratchet and the ratchet teeth, causing the connecting wires being wound to be loosened, providing a long enough connecting wire for the movement of the test ports. S4. Buffer of the connecting wires of the test ports: During the winding process of the connecting wires, gas is filled into or extracted from the sealed cavity through the filling port. When filling gas, the support rod expands and pushes some of the connecting wires outwards. When the connection port changes to an arc-shaped arrangement, the support rod moves into the air pressure cavity, causing several connecting wires to move, providing a long enough connecting wire. An air pressure cavity is formed between the support rod and the sealed cavity, and the elastic characteristics of the spring are replaced by the air pressure difference, which can avoid the influence of external factors on its elastic function.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the cooperation of the card slot, the snap ring and the first spring by the insertion and extraction assembly of the present invention, two insertion and extraction effects of linear and arc-shaped arrays are achieved. The former is efficient and fast, simulating manual extraction, and the latter realizes the multi-angle inclined insertion and extraction test to comprehensively detect the performance of the graphics card; the winding assembly utilizes the meshing characteristics of the ratchet teeth and the ratchet, combined with the wire threading channel, to effectively prevent the winding of the connecting wires and ensure the smooth movement of the test ports; the stretching assembly replaces the spring with an air pressure cavity, and flexibly adjusts the support rod by inflating or deflating to provide connecting wires of appropriate lengths for the test ports arranged in different arrays, with strong stability; the test mechanism can adjust the lengths of the connecting frame and the push rod, and with the aid of the pneumatic frame and the rubber strip, it can adapt to various sizes of graphics cards; the overall device simulates manual operations and different inclined states during the test, making the test results highly conform to the actual use scenario, effectively guaranteeing the comprehensiveness and accuracy of the graphics card performance detection.

[0016] 2. During the plugging and unplugging test of the present invention, the test port shakes through the airbag, and an inclined force is applied during unplugging to simulate the effect of manual unplugging; the multi-angle plugging and unplugging test can simulate the plugging and unplugging conditions under different inclined states, making the test results closer to the actual use and helping to discover potential problems that may occur in the actual application of the graphics card.

[0017] 3. In the present invention, the winding component is slidably connected through the engagement or non-engagement of the ratchet and the pawl to realize the winding and unwinding operations of the connecting line of the test port; during the test, it can wind the connecting line to avoid it being messy, and can timely unwind it when the port moves. At the same time, the threading channel formed by the tripod and the inner wall of the support cylinder can prevent the connecting line of the port from being wound too short and affecting the movement of the test port. Moreover, in the test mechanism, the lengths of the connecting frame and the push rod can be adjusted through threaded connection. At the same time, the pneumatic frame and the rubber strip can wrap graphics cards of different sizes, realizing the fixation and testing of graphics cards of various sizes, and improving the versatility of the equipment.

[0018] 4. The stretching component inflates or deflates the air pressure chamber through the filling port, causing the support rods to expand or converge; when the fixed boxes are arranged in an arc array and the length of the connecting line of the test port is insufficient, the compression of the support rods can provide a long enough connecting line; using the air pressure difference to replace the elastic characteristics of the spring, the elastic effect is not affected by external factors, ensuring the stability of the equipment operation.

[0023] Example 2, as Figure 4-5 and Figure 9-10As shown, in the embodiment of the present invention, the plugging and unplugging assembly 3 includes a push plate 31. The push plate 31 is hinged to the output end of the push rod 231 and is slidably connected to the top of the support plate 26. A cover plate 32 is fixedly connected to the top of the push plate 31. Six fixing boxes 33 are jointly hinged to the inner walls on both sides of the push plate 31 in a linear array. Adjacent two fixing boxes 33 are movably connected through a waist-shaped hinge plate 331. Air bags 332 are fixedly connected to the inner walls on both sides of each fixing box 33. A number of first springs 34 are fixedly connected to the inner wall of one side of the push plate 31 in a linear array, and the first springs 34 are fixedly connected to the side surface of the waist-shaped hinge plate 331. Slide plates 35 are rotatably connected to the tops of four of the fixing boxes 33. A handle 36 is rotatably connected to the right side of the top of each slide plate 35. A card slot 361 is provided on the side surface of the handle 36. Four waist-shaped holes 37 are provided on the top of the cover plate 32, and the handle 36 passes through the waist-shaped holes 37. Snap rings 38 are fixedly connected to the top of the cover plate 32 at the edges of the waist-shaped holes 37. The card slot 361 is adapted to be snap-fitted with the snap ring 38.

[0024] Specifically, by engaging or unlocking the card slot 361 with the snap ring 38, and the first spring 34 applying a force to the six fixing boxes 33, the six fixing boxes 33 are caused to have a linear array plugging and unplugging effect or an arc array plugging and unplugging effect, realizing efficient and rapid plugging and unplugging tests and multi-angle plugging and unplugging tests.

[0025] Embodiment 3, as Figure 3 and Figure 7 As shown, in the embodiment of the present invention, the winding assembly 4 includes two support cylinders 41. The two support cylinders 41 are symmetrically fixedly connected to both sides of the support plate 26. Tripods 42 are fixedly connected to the interiors of the two support cylinders 41, and three wire threading channels are formed between the tripods 42 and the inner walls of the support cylinders 41. A second motor 43 is fixedly connected to the left side of each tripod 42. A ratchet pawl 44 is fixedly connected to the output shaft of the second motor 43.

Ratchet teeth 46 are fixedly connected to the inner wall of the wire winding cylinder 45, and the ratchet teeth 46 are meshed with the ratchet pawl 44.

[0026] Specifically, by engaging or non-engaging and sliding connecting the ratchet teeth 46 with the ratchet pawl 44, when engaging, the connecting wire of the test port is wound, and when non-engaging and sliding connecting, during the movement of the connection port test, the connecting wire of the test port is unwound, preventing the winding of the connecting wire from affecting the test.

[0027] It should be noted that by forming three wire threading channels between the tripod 42 and the inner wall of the support cylinder 41, the winding of the connecting wire of the port on the left side of the tripod 42 can be prevented, resulting in too short a line length and affecting the movement of the test port.

[0028] Embodiment 4, as Figure 3 and Figure 7-8As shown, as another embodiment of the present invention, the stretching component 5 includes a fixed disk 51. The fixed disk 51 is fixedly connected to one side of the tripod 42. A sealing cavity 511 is arranged inside the fixed disk 51. A filling port 512 is arranged on the surface of the fixed disk 51, and the filling port 512 communicates with the sealing cavity 511. A plurality of support rods 52 are slidably connected in an annular array inside the sealing cavity 511. The ends of the plurality of support rods 52 and the sealing cavity 511 form a pneumatic cavity. A groove 521 is opened at the top of each support rod 52.

[0029] Specifically, the pneumatic cavity is inflated or deflated through the filling port 512, causing the plurality of support rods 52 to expand or gather. When the plurality of fixed boxes 33 are in an arc array, the length of the test port connection line in the fixed box 33 is insufficient. Through the compression of the support rods 52, a sufficient length of connection line is provided for the test port. Among them, the pneumatic cavity provides an elastic effect on the support rods 52, so that after the support rods 52 are compressed, they expand again. Compared with using a spring, this method is not affected by external factors in terms of the elastic effect.

[0030] Embodiment 5, a method for using a computer graphics card plugging and unplugging test device, includes the following steps: S1. Test preparation and graphics card fixation: First, place the computer graphics card on the top of the support plate 26. Then, through the pneumatic system, make the pneumatic frame 27 move downward on the sliding rod 25, so that a plurality of rubber strips 28 wrap around the surface of the graphics card. Then, install the test port inside the fixed box 33 and fix it through the airbag 332, and plug it into the graphics card interface. Observe whether it is connected through the test platform 1, and adjust the lengths of the connecting frame 23 and the push rod 231 through threaded connection to adapt to graphics cards of various sizes; S2. Graphics card plugging and unplugging test; S2.1. Linear array plugging and unplugging test: First, rotate the handle 36 to make the card slot 361 and the snap ring 38 in a clamped state, causing the plurality of fixed boxes 33 to be arranged in a linear array. Then, make the first motor 21 work through the external circuit mechanism to drive the turntable 22, apply a force to the push rod 231, and make it reciprocate. Further, make the push plate 31 reciprocate horizontally on the support plate 26. Among them, the test port shakes through the airbag 332, and an inclined force is applied to it during the pulling out process to simulate the manual pulling out effect and achieve efficient and rapid plugging and unplugging tests; S2.2. Arc-shaped arrangement plug and unplug test: Rotate the handle 36 so that the card slot 361 and the snap ring 38 are in a non-engaged connection state. Then, apply a force to the kidney-shaped hinge plate 331 through the first spring 34 to expand several fixed boxes 33 to form an arc-shaped array arrangement. During use, drive the push plate 31 to reciprocate translationally on the support plate 26, causing the test ports arranged in an arc to be inserted into the graphics card connection port. During this process, the test ports are in an inclined state to simulate the insertion effect of the test ports in an inclined state. During the process of pulling out the test ports, the test ports at both ends are pulled out first, and an inclined pull-out is formed by the force applied by the first spring 34. The test ports in the middle are pulled out translationally to achieve the plug and unplug effect at multiple angles; S3. Winding of the test port connection lines: During the test, the connection lines pass through the wire threading channels respectively, and then the second motor 43 drives the ratchet 44 to rotate through the external circuit mechanism. Among them, the ratchet 44 is engaged with the ratchet teeth 46, causing the wire winding cylinder 45 to rotate and helically wind the three connection lines. When several test ports move to the left, the connection lines being wound are connected in a non-engaged sliding manner through the ratchet 44 and the ratchet teeth 46, causing the connection lines being wound to be loosened to provide a long enough connection line for the movement of the test ports; S4. Buffering of the test port connection lines: During the process of winding the connection lines, gas is filled into or extracted from the sealing cavity 511 through the filling port 512. When filling gas, the support rod 52 expands to expand part of the connection lines outward. When the connection port changes to an arc-shaped arrangement, the support rod 52 moves into the air pressure cavity, causing several connection lines to move to provide a long enough connection line. An air pressure cavity is formed between the support rod 52 and the sealing cavity 511, and the elastic characteristics of the spring are replaced by the air pressure difference, which can avoid the influence of external factors on its elastic function.

[0031] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.

Test preparation and graphics card fixation: First, place the computer graphics card on the top of the support plate, and then through the pneumatic system, move the pneumatic rack downward on the sliding rod so that a plurality of rubber strips wrap around the surface of the graphics card. Then, install the test port inside the fixed box, fix it through the airbag, and plug it into the graphics card interface. Observe whether it is connected through the test platform, and adjust the lengths of the connecting frame and the push rod through threaded connection to adapt to graphics cards of various sizes; S2. Graphics card plugging and unplugging test; S2.

1. Linear array plugging and unplugging test: First, turn the handle to make the card slot and the snap ring in a clamped state, so that a plurality of fixed boxes are arranged in a linear array. Then, make the first motor work through the external circuit mechanism to drive the turntable, apply a force to the push rod to make it move reciprocally, and further make the push plate move reciprocally on the support plate. Among them, the test port shakes through the airbag, and an inclined force is applied to it during the unplugging process to simulate the manual unplugging effect and achieve efficient and fast plugging and unplugging tests; S2.

2. Arc arrangement plugging and unplugging test: Turn the handle to make the card slot and the snap ring in a non-clamped connection state. Then, apply a force to the waist-shaped hinge plate through the first spring to open a plurality of fixed boxes to form an arc array arrangement. During use, drive the push plate to move reciprocally on the support plate by rotation, so that the test ports arranged in an arc are inserted into the graphics card connection ports. During this process, the test ports are in an inclined state to simulate the plugging effect of the test ports in an inclined state. During the unplugging process of the test ports, the test ports at both ends are unplugged first, and an inclined unplugging is formed through the force applied by the first spring. The middle test port is unplugged in a translational manner to achieve a multi-angle plugging and unplugging effect; S3. Winding of the connecting wires of the test ports: During the test, the connecting wires pass through the wire threading channels respectively, and then the second motor is driven by the external circuit mechanism to drive the pawl to rotate. Among them, through the meshing connection between the pawl and the ratchet teeth, the wire winding cylinder rotates to helically wind the three connecting wires. When a plurality of test ports move to the left, the connecting wires being wound are connected through non-meshing sliding between the pawl and the ratchet teeth, so that the connecting wires being wound are loosened to provide enough long connecting wires for the movement of the test ports; S4. Buffering of the connecting wires of the test ports: During the winding process of the connecting wires, gas is filled into or extracted from the sealing cavity through the filling port. When filling gas, the support rod expands to push some of the connecting wires outward. When the connection ports change to an arc arrangement, the support rod moves into the air pressure cavity, causing a plurality of connecting wires to move to provide enough long connecting wires. An air pressure cavity is formed between the support rod and the sealing cavity, and the elastic characteristics of the spring are replaced by the air pressure difference, which can avoid the influence of external factors on its elastic function.
