The so-called computer hardware refers to various physical devices that make up a computer and the physical structure devices used in a computer system. After the computer hardware is manufactured, it needs to undergo multiple performance tests to ensure it is qualified before it can be put into use. Among them, it is necessary to conduct a drop resistance performance test to ensure its hardness, stability, etc. The existing computer hardware performance detection devices can only detect a group of computer hardware.

[0018] The computer hardware performance detection device provided by the present invention has the following beneficial effects
[0019] 1. By providing a linkage structure in the present invention, starting the driving motor drives the driving shaft column to rotate. The driving shaft column drives the driving gear to rotate. The driving gear meshes with the transmission gear to drive the transmission gear to rotate. The transmission gear drives the first lead screw to rotate. The first lead screw drives the driving pulley to rotate. The driving pulley drives the driven pulley to rotate through the synchronous belt. Then the driven pulley drives the second lead screw to rotate, so that the first lead screw and the second lead screw rotate simultaneously, and rotate and mesh with the threaded holes on the moving belt plate. The moving belt plate is limited and guided on the guiding convex strip through the guiding groove. Then the first lead screw and the second lead screw drive the two groups of moving belt plates to move and adjust, so as to lift the two groups of computer hardware to a certain height.

[0020] 2. By providing a fixing structure in the present invention, turning on the electromagnet pushes the moving magnetic plate to move based on the principle of like poles repelling each other. The moving magnetic plate drives the clamping frame to move in the opposite direction through the connecting vertical plate. Then the computer hardware is placed between the clamping frames. At this time, the electromagnet is turned off, and then the moving magnetic plate loses magnetic force. Because the moving magnetic plate squeezes the spring on the connecting slide rod when moving, causing the spring to produce elastic deformation. When the pressure is lost, the spring produces elasticity at this time, thus pushing the moving magnetic plate to move towards each other. The moving magnetic plate drives the clamping frame to clamp and fix the computer hardware, so that it can fix hardware of different sizes, enabling the detection device to be compatible with more types of computer hardware and enabling anti-drop performance detection for all of them, greatly expanding the application range of the device and meeting the diverse detection needs.
[0021] 3. By providing a limiting component in the present invention, different detection plates can be replaced through the setting of the square groove for detection. Through the cooperation of the blocking cross plate, the inserted convex plate and the limiting groove, the detection plate can be limited to prevent movement. Through the setting of the pressing knob, the second hinge frame can be horizontally or vertically pressed and limited, facilitating the replacement of the detection plate.

Guide grooves 2052 are opened on both sides of the moving belt plate 205 of the threaded hole 2051. The guide grooves 2052 are fitted and slidably installed on the outer side of the guide rib 2011.
[0059] A scale plate 206 is arranged at the middle of the top of the fixed support frame 201. A fixed cross bar 2061 is fixedly connected to the top of the scale plate 206.
[0060] By starting the driving motor 2031 to drive the driving shaft column 2032 to rotate, the driving shaft column 2032 drives the driving gear 2033 to rotate. The driving gear 2033 meshes with the transmission gear 2034 to rotate. The transmission gear 2034 drives the first lead screw 202 to rotate. The first lead screw 202 drives the driving pulley 2035 to rotate. The driving pulley 2035 drives the driven pulley 2036 to rotate through the timing belt 204. Then, the driven pulley 2036 drives the second lead screw 2021 to rotate, so that the first lead screw 202 and the second lead screw 2021 rotate simultaneously, and rotate and mesh with the threaded hole 2051 on the moving belt plate 205. The moving belt plate 205 is limited and guided on the guide rib 2011 through the guide groove 2052. Then, the first lead screw 202 and the second lead screw 2021 drive the two moving belt plates 205 to move and adjust, so as to lift the two sets of computer hardware to a certain height. By setting the scale plate 206, the height of the computer hardware lifted can be accurately controlled.
[0061] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 6 shown, a fixing structure 3 is arranged at the front end of the moving belt plate 205. The fixing structure 3 includes a connecting convex block 301, a connecting frame 3011 and a moving groove 3012. A connecting convex block 301 is fixedly connected to the front end of the moving belt plate 205. A connecting frame 3011 is fixedly connected to the front end of the connecting convex block 301. A moving groove 3012 is opened inside the connecting frame 3011.
[0062] An electromagnet 302 is fixedly installed at the middle of the moving groove 3012. Connecting slide rods 3021 are fixedly connected to both sides of the electromagnet 302 and the two ends of the moving groove 3012. A spring 3022 is arranged on the outer side of the connecting slide rod 3021.
[0063] On both sides of the electromagnet 302, there are moving magnetic plates 303. The moving magnetic plates 303 are provided with sliding support holes 3031, and the moving magnetic plates 303 are slidably mounted on the connecting sliding rods 3021 through the sliding support holes 3031.
[0064] At the bottom of the connecting frame 3011, there is a through groove 3013. At the bottom of the moving magnetic plate 303, there is a fixed connecting vertical plate 3032. The connecting vertical plate 3032 passes through the through groove 3013 and is fixedly connected to the clamping frame 3033.
[0065] By turning on the electromagnet 302, the moving magnetic plate 303 is pushed to move based on the principle of like poles repelling each other. The moving magnetic plate 303 drives the clamping frame 3033 to move in the opposite direction through the connecting vertical plate 3032. Then, the computer hardware is placed between the clamping frames 3033. At this time, the electromagnet 302 is turned off, and thus the moving magnetic plate 303 loses magnetic force. Because the spring 3022 on the connecting sliding rod 3021 is compressed when the moving magnetic plate 303 moves, the spring 3022 undergoes elastic deformation. When the pressure is lost, the spring 3022 generates elasticity at this time, thereby pushing the moving magnetic plates 303 to move towards each other, and the moving magnetic plates 303 drive the clamping frames 3033 to clamp and fix the computer hardware.
[0066] Embodiment Three: On the basis of Embodiment One and Embodiment Two, as Figure 7 and Figure 8 shown, a limiting component 4 is provided at the front end of the fixed support 1. The limiting component 4 includes a test frame 401, a square groove 4011, and a detection plate 402. The front end of the fixed support 1 is fixedly connected to the test frame 401. The bottom of the test frame 401 is provided with a square groove 4011, and a detection plate 402 is provided inside the test frame 401.
[0067] The front end of the test frame 401 is fixedly connected to a connecting cross plate 403. One end of the connecting cross plate 403 is fixedly connected to a fixed convex plate 4031. A limiting groove 4032 is opened on the fixed convex plate 4031. The other end of the connecting cross plate 403 is fixedly connected to a first hinge frame 4033. The first hinge frame 4033 is hinged to the second hinge frame 404 through a shaft pin 4034.
[0068] One end of the shaft pin 4034 is engaged with a pressing knob 4035. The second hinge frame 404 is fixedly connected to a blocking cross plate 4041. The end of the blocking cross plate 4041 is fixedly connected to an insertion convex plate 4042. The insertion convex plate 4042 is fitted and clamped in the limiting groove 4032.
[0069] Through the setting of the square groove 4011, different detection plates 402 can be replaced for detection. Through the cooperation of the blocking cross plate 4041, the inserted convex plate 4042 and the limiting groove 4032, the detection plate 402 can be limited to prevent movement. Through the setting of the pressing knob 4035, the second hinge frame 404 can be horizontally or vertically pressed and limited, facilitating the replacement of the detection plate 402.
[0070] Specific usage and function of this embodiment: In the present invention, the detection board 402 to be detected needs to be placed in the test frame 401, and then the blocking cross plate 4041 is rotated so that the insertion convex plate 4042 is clamped into the limit groove 4032, thereby limiting the detection board 402 to prevent it from moving. Then, the pressing knob 4035 is rotated to press and fix the second hinge frame 404 to prevent the second hinge frame 404 from driving the blocking cross plate 4041 to rotate. Then, by turning on the electromagnet 302, the moving magnetic plate 303 is pushed to move based on the principle of like poles repelling each other. The moving magnetic plate 303 drives the clamping frame 3033 to move in the opposite direction through the connecting vertical plate 3032. Then, the computer hardware is placed between the clamping frames 3033. At this time, the electromagnet 302 is turned off, and thus the moving magnetic plate 303 loses its magnetic force. Because the moving magnetic plate 303 squeezes the spring 3022 on the connecting slide rod 3021 when moving, causing the spring 3022 to produce elastic deformation. When the pressure is removed, the spring 3022 generates elasticity at this time, thereby pushing the moving magnetic plate 303 to move towards each other. The moving magnetic plate 303 drives the clamping frame 3033 to clamp and fix the computer hardware, enabling it to fix hardware of different sizes, making the detection device compatible with more types of computer hardware, enabling all of them to perform drop resistance performance detection, greatly expanding the applicable range of the device, meeting diverse detection requirements. Finally, by starting the driving motor 2031 to drive the driving shaft column 2032 to rotate, the driving shaft column 2032 drives the driving gear 2033 to rotate, the driving gear 2033 meshes with the transmission gear 2034 to rotate, the transmission gear 2034 drives the first lead screw 202 to rotate, the first lead screw 202 drives the driving pulley 2035 to rotate, the driving pulley 2035 drives the driven pulley 2036 to rotate through the synchronous belt 204. Then, the driven pulley 2036 drives the second lead screw 2021 to rotate, enabling the first lead screw 202 and the second lead screw 2021 to rotate simultaneously, and they rotate and mesh with the threaded holes 2051 on the moving belt plate 205. The moving belt plate 205 is limited and guided on the guiding convex strip 2011 through the guiding groove 2052. Then, the first lead screw 202 and the second lead screw 2021 drive the two groups of moving belt plates 205 to move and adjust, raising the two groups of computer hardware to a certain height, enabling the simultaneous drop resistance performance detection of multiple computer hardware samples, changing the traditional mode of detecting one by one, greatly accelerating the detection speed, meeting the demand for rapid detection of computer hardware in large-scale production scenarios, effectively ensuring the product launch rhythm and production progress. Then, the electromagnet 302 is turned on again, and the moving magnetic plate 303 is pushed to move based on the principle of like poles repelling each other. The moving magnetic plate 303 drives the clamping frame 3033 to move in the opposite direction through the connecting vertical plate 3032, causing the computer hardware to freely fall onto different detection boards 402, and thus the drop resistance performance data of the computer hardware in multiple environments can be obtained in one detection, making the data dimension richer and more comprehensive, effectively avoiding the one-sidedness of the detection results in a single environment.Make the detection results better reflect the true drop resistance of computer hardware in actual complex usage scenarios, providing a more reliable reference for product quality assessment.
