Description

Technical Field

[0001] The present invention relates to the technical field of computer testing, and in particular to a computer testing device and method. Background Art

[0002] The storage of big data is inseparable from the server, and the data in the server ultimately falls on the underlying hard disk. The reliability and stability of the hard disk of a large-capacity storage server are the key points of server testing. The reliability and stability of the hard disk are crucial to the security of data storage.

[0003] According to a disclosed computer storage hard drive testing device (Publication No. CN220367590U), the aforementioned application utilizes a data cable placement hole to neatly arrange the wiring harness within the hole, facilitating storage and organization, reducing crossovers, tangles, and bends, and extending the harness's service life while maintaining a simple structure. However, while the placement hole allows for neat placement of the wiring harness, inadvertent pulling on the harness can cause the data cable to fall out of the connector, potentially impacting subsequent testing operations.

[0013] The present invention also proposes a computer testing method, which comprises the following steps: S1.

When the data cable is inserted into the connection slot, the data cable is placed in the placement slot, and the knob is turned forward to rotate the threaded rod while moving downward, driving the movable plate to move downward, so that the L-shaped extrusion rod moves downward to squeeze the guide block, so that the guide block approaches the placement slot, so that the reset spring is stretched, and when the guide block approaches the placement slot, the data cable placed in the placement slot is aligned so that the data cable is at the bottom of the clamping block.

[0021] In order to protect the connection slot 3, the specific protection component 8 includes an L-shaped connecting rod 801, a bevel block 802, a connecting rod 803, a transmission block 804, a connecting spring 805, a fixed block 806, a rotating rod 807, a baffle 808, a rotating block 809, a sealing cylinder 810, an air blow pipe 811, a push rod 812, a piston plate 813, an arc block 814, a transmission spring 815, a fixed rod 816, and a hinge block 817; one end of the L-shaped connecting rod 801 is fixed to the side wall of the movable plate 706, and the other end of the L-shaped connecting rod 801 is fixed with a bevel block 802, and the test box housing 1 The side wall of the test box 1 is penetrated by a connecting rod 803, and the penetration is slidably connected. A transmission block 804 is fixed to one end of the connecting rod 803, and a connecting spring 805 is fixed to the side wall of the transmission block 804. The side of the connecting spring 805 away from the transmission block 804 is fixed to the side wall of the test box housing 1. By setting the connecting spring 805, the transmission block 804 can be reset. A fixed block 806 is fixed to the top of the test box housing 1. A rotating rod 807 is penetrated in the fixed block 806, and the rotating rod 807 is rotatably connected to the penetration of the fixed block 806. The outer wall of the rotating rod 807 is fixed with a shielding plate 80 8. By setting a shielding plate 808, the data line connection slot 3 is shielded to prevent dust or liquid from falling on the data line connection, which may easily cause a short circuit in the electrical components. Rotating blocks 809 are fixed at both ends of the rotating rod 807. A hinge block 817 is slidably installed on the inner side of the rotating block 809. The side wall of the hinge block 817 is hinged to the end point of the connecting rod 803. A sealing cylinder 810 is fixed to the side wall of the shielding plate 808. A piston plate 813 is slidably installed on the inner wall of the sealing cylinder 810. A push rod 812 is fixed to the side wall of the piston plate 813. The end point of the push rod 812 is fixed to the arc block 814. Test A fixing rod 816 is fixed to the top of the electrical box housing 1, and a transmission spring 815 is fixed to the side wall of the arc block 814. The side of the transmission spring 815 away from the arc block 814 is fixed to the side wall of the baffle 808, and an air blowing pipe 811 is fixed to the right side of the sealing cylinder 810, and the air blowing pipe 811 is connected to the sealing cylinder 810. The air is discharged through the air blowing pipe 811, which can blow away the dust attached to the connection slot 3, so that the connection slot 3 can be kept clean, and a large amount of dust attached to the connection slot 3 can be prevented, which can easily cause dust to easily enter the connection slot 3 and cause damage to the connection slot 3.

[0022] In order to prevent the device from vibrating during operation, the specific stabilizing component 9 includes a long rod 901, a long plate 902 and a suction cup 903; the long rod 901 is fixed to the bottom of the movable plate 706, and the long rod 901 passes through the placement block 702 and the support plate 6, and is slidably connected at the penetration point, and the setting of the long rod 901 can guide the movable plate 706, so that when the threaded rod 704 is rotated, the movable plate 706 is not driven to rotate. The long plate 902 is fixed at one end of the long rod 901 away from the movable plate 706, and multiple groups of suction cups 903 in a linear array are fixed to the bottom of the long plate 902. When the data cable is tightened, the suction cup 903 will be adsorbed on the placement surface of the device, which can improve the stability of the device and prevent the device from vibrating and displacing during operation, affecting the detection of the device.

[0023] This embodiment also proposes a computer testing method, comprising the following steps: S1. When the computer needs to be tested, place the device at the designated location and connect the computer to be tested to the testing device via the data cable connection slot 3 for testing; When the data line is inserted into the connection slot 3, the data line is placed in the placement slot 703, and the knob 705 is turned forward to make the threaded rod 704 rotate and move downward, driving the movable plate 706 to move downward. When the movable plate 706 moves downward, the L-shaped extrusion rod 707 moves downward to squeeze the inclined surface of the guide block 708, so that the guide block 708 approaches the placement slot 703, and the return spring 709 is stretched. When the guide block 708 approaches the placement slot 703, the data line placed in the placement slot 703 is aligned so that the data line is at the bottom of the clamping block 713. When the data line is aligned well, and when the movable plate 706 continues to move downward, the clamping block 713 contacts the data line at the placement slot 703, and the data line is clamped and fixed by the clamping block 713, which can prevent the data line from being accidentally pulled, causing the connector of the data line to fall off from the connection slot 3, affecting the detection operation of the computer; S3. When the movable plate 706 moves downward, the L-shaped connecting rod 801 moves downward, and the L-shaped connecting rod 801 drives the inclined block 802 to move downward. When the inclined block 802 moves downward to contact the inclined surface of the transmission block 804, the transmission block 804 is squeezed and moves toward the test box housing 1, driving the connecting rod 803 to move, compressing the connecting spring 805. When the connecting rod 803 moves, it can squeeze the hinge block 817 and the rotating block 809, so that the rotating block 809 drives the rotating rod 807 to rotate forward. The rotating rod 807 drives the shielding plate 808 to rotate, shielding the top of the connecting slot 3 to prevent dust or liquid from falling on the connection of the data cable, which may easily cause a short circuit in the electrical components. S4. When the shielding plate 808 rotates, the arc block 814 moves away from the fixed rod 816. Since the transmission spring 815 is in a stretched state, the arc block 814 moves toward the sealing cylinder 810, causing the push rod 812 to move into the sealing cylinder 810, which in turn causes the piston plate 813 to move within the sealing cylinder 810. The air in the sealing cylinder 810 is discharged from the blowing pipe 811, and air is blown toward the connecting slot 3 to blow away the dust adhering to the connecting slot 3. S5, and when the movable plate 706 moves downward, it can drive the long rod 901 to move downward, so that the long plate 902 moves downward. When the pressing block 713 presses the data line, the suction cup 903 is adsorbed on the ground, which can improve the stability of the device and prevent the device from vibrating and moving during operation, affecting the detection of the device. When the computer test is completed, the knob 705 can be reversed to make the threaded rod 704 rotate and move upward, driving the movable plate 706 to move upward, so that the movable plate 706 can drive the pressing block 713 to move upward without pressing the data line. When the movable plate 706 moves upward, it can drive the L-shaped extrusion rod 707 to move upward, so that the L-shaped extrusion rod 707 does not contact the inclined surface of the guide block 708. Because the reset spring 709 is in a stretched state, the guide block 708 can be reset. When the movable plate 706 moves upward, it can drive the L-shaped connecting rod 801 and the inclined block 802 to move upward without squeezing the inclined surface of the transmission block 804. 5 is in a compressed state, which causes the transmission block 804 to reset, causing the transmission block 804 to drive the connecting rod 803 to approach the movable plate 706, causing the connecting rod 803 to drive the hinge block 817 to move, causing the rotating block 809 to reverse, driving the shielding plate 808 to reset, and when the shielding plate 808 reverses, when the arc surface of the arc block 814 rotates to contact the top of the fixed rod 816, and the elastic coefficient of the connecting spring 805 is greater than the elastic coefficient of the transmission spring 815, the arc block 814 will be squeezed. The force causes the arc block 814 to move away from the sealing cylinder 810, and the push rod 812 drives the piston plate 813 to move in the sealing cylinder 810, so that the blowing pipe 811 sucks air and performs the next blowing operation on the connection slot 3. When the shielding plate 808 is opened, the data cable can be pulled out from the connection slot 3, and when the movable plate 706 moves upward, the long rod 901 and the long plate 902 can be driven to move upward, so that the suction cup 903 moves upward, so that the suction cup 903 does not perform the adsorption operation, and the equipment can be stored.

[0024] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

When it is necessary to test the computer, place the device at a designated location, and connect the computer to be tested to the testing device through the data cable connection slot (3) for testing; S2, when the data line is inserted into the connection slot (3), after the connection is completed, the data line is placed in the placement slot (703), and the knob (705) is turned forward to make the threaded rod (704) rotate and move downward, driving the movable plate (706) to move downward, and the L-shaped extrusion rod (707) moves downward to squeeze the guide block (708), so that the guide block (708) approaches the placement slot (703), so that the reset spring (709) is stretched, and when the guide block (708) approaches the placement slot (703), the data line placed in the placement slot (703) is aligned, so that the data line is at the bottom of the clamping block (713), and when the data line is aligned, and when the movable plate (706) continues to move downward, the clamping block (713) will contact the data line at the placement slot (703), and the data line is clamped and fixed by the clamping block (713); S3, when the moving plate (706) moves downward, the inclined surface block (802) is driven to move downward through the L-shaped connecting rod (801), and when the inclined surface block (802) moves downward to contact the inclined surface of the transmission block (804), the transmission block (804) is pressed toward the test electric box housing 1, and the connecting rod (803) is driven to move, and the hinge block (817) and the rotating block (809) are pressed, so that the rotating rod (807) drives the shielding plate (808) to rotate, thereby shielding the top of the connecting slot (3); S4. When the shielding plate (808) rotates, the arc block (814) moves away from the fixing rod (816). The transmission spring (815) cooperates to move the piston plate (813) in the sealing cylinder (810), so that air is discharged from the blowing pipe (811) and blows toward the connecting slot (3), thereby blowing away dust attached to the connecting slot (3); S5. When the movable plate (706) moves downward, it can drive the long rod (901) to move downward, causing the long plate (902) to move downward. When the pressing block (713) presses the data line, the suction cup (903) is adsorbed on the ground, which can improve the stability of the device.
