[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 2-4As shown, the present invention proposes a pressing device for an ICT test fixture, comprising a support frame 1, a sliding groove 2 on one side of the support frame 1, a sliding block 3 slidably connected inside the sliding groove 2, a swing rod 8 disposed inside the support frame 1 near the sliding groove 2, a lubrication hole 4 disposed inside the sliding groove 2, through which the sliding block 3 inside the sliding groove 2 can be lubricated, the lubrication hole 4 being connected to the sliding groove 2, the swing rod 8 being ">" shaped, the structure of the swing rod 8 being designed to facilitate control of the rotation of the swing rod 8 from one side, a reset shaft 12 being fixedly connected inside the swing rod 8, the reset shaft 12 being rotatably connected inside the support frame 1, a pressing tube 6 disposed on one side of the swing rod 8 near the lubrication hole 4, a connector 5 being fixedly connected to one end of the pressing tube 6, the connector 5 being connected to the lubrication hole 4 and the pressing tube 6. The extrusion tube 6 delivers lubricating oil along the extrusion tube 6, connector 5, and lubrication hole 4 to the sliding groove 2 to lubricate the sliding block 3. A one-way valve 15 is installed inside the connector 5 to prevent the lubricating oil inside the extrusion tube 6 from flowing back. A detection plate 20 is fixedly connected to the side of the sliding block 3 away from the sliding groove 2. A pressing rod 9 is fixedly connected to the bottom of the detection plate 20 near the sliding block 3. The end of the pressing rod 9 away from the detection plate 20 abuts against the side of the swing rod 8. When the detection plate 20 descends, it drives the pressing rod 9 to press down the swing rod 8, causing the swing rod 8 to rotate inside the support frame 1, thereby squeezing the lubricating oil inside the extrusion tube 6. A placement platform 21 is provided below the detection plate 20. The detection plate 20 presses on the placement platform 21 to detect the ICT above the placement platform 21.

[0024] also Figure 2 and Figure 4 As shown, an extrusion rod 7 is slidably connected inside the extrusion tube 6 at a position away from the connector 5. A connecting block 10 is fixedly connected to the end of the extrusion rod 7 away from the extrusion tube 6. A rotating block 11 is rotatably connected to the outside of the connecting block 10 at a position away from the extrusion rod 7. The rotation of the rotating block 11 and the connecting block 10 avoids the extrusion rod 7 from breaking due to different force application positions. The end of the rotating block 11 away from the connecting block 10 is fixedly connected to one side of the swing rod 8. By driving the rotating block 11 and the connecting block 10 through the swing rod 8, the extrusion rod 7 can be pushed to extrude the lubricating oil inside the extrusion tube 6. An oil inlet pipe 16 is fixedly connected to the outside of the extrusion tube 6 and is connected to the extrusion tube 6. A support block 23 is fixedly connected to the outside of the extrusion tube 6. The side of the support block 23 away from the extrusion tube 6 is fixedly connected to the inside of the support frame 1. The support block 23 can inject lubricating oil into the extrusion tube 6.

[0025] in addition Figure 5 and Figure 6As shown, a rotating groove 14 is provided inside the support frame 1 near the reset shaft 12. A worm spring 13 is fixedly connected to the outside of the rotating groove 14. When the swing rod 8 rotates by the reset shaft 12, it will drive the worm spring 13 to wind up. The worm spring 13 is fixedly connected to the inside of the rotating groove 14. When the support rod 18 loses pressure, the worm spring 13 reverses inside the rotating groove 14 to push the reset shaft 12 and drive the swing rod 8 to reset.

[0026] also Figure 1 , Figure 2 and Figure 5 As shown, an oil reservoir 17 is fixedly connected to the end of the oil inlet pipe 16 away from the extrusion pipe 6. The oil reservoir 17 is connected to the oil inlet pipe 16. Once the lubricating oil is added into the oil reservoir 17, it is not necessary to add lubricating oil at any time. The oil reservoir 17 is fixedly connected inside the support frame 1. A telescopic rod 19 is fixedly connected to the top of the detection plate 20. The telescopic rod 19 can control the raising and lowering of the detection plate 20. A support rod 18 is fixedly connected to the end of the telescopic rod 19 away from the detection plate 20. The support rod 18 is fixedly connected to the top of the support frame 1. The support rod 18 can support the extension and retraction of the telescopic rod 19. A base 22 is fixedly connected to the bottom of the placement platform 21. The base 22 is fixedly connected to the bottom of the support frame 1. The base 22 supports the placement platform 21 for detection.

[0027] In this embodiment, the ICT is first placed on the placement platform 21. When in use, the telescopic rod 19 fixed by the support rod 18 pushes the detection plate 20 down. The detection plate 20 relies on the sliding block 3 to slide inside the sliding groove 2 to prevent the detection plate 20 from shaking when it is pressed down. When the detection plate 20 is pressed down, it will drive the swing rod 8 to rotate inside the support frame 1 by relying on the reset shaft 12. When the swing rod 8 rotates, it will push the rotating block 11 and the connecting block 10 to move, so that the connecting block 10 drives the extrusion rod 7 to extrude the lubricating oil inside the extrusion tube 6. The lubricating oil enters the sliding groove 2 along the connector 5 and the lubrication hole 4, so that the lubricating oil lubricates the sliding block 3 sliding inside the sliding groove 2.

[0028] When the telescopic rod 19 drives the detection plate 20 to descend, the swing rod 8 will drive the reset shaft 12 to wrap around the worm spring 13 and tighten inside the rotating groove 14. When the telescopic rod 19 rises, the detection plate 20 will disengage from the surface of the swing rod 8. At this time, the support rod 18 will drive the reset shaft 12 and the swing rod 8 to rotate in the opposite direction, thereby allowing the swing rod 8 to reset.

[0029] When the swing rod 8 resets, it will drive the rotating block 11, the connecting block 10 and the extrusion rod 7 to reset. When the extrusion rod 7 resets, the one-way valve 15 closes, and the lubricating oil will be drawn from the inside of the oil tank 17 along the oil inlet pipe 16, thereby balancing the internal pressure of the extrusion tube 6. This makes it convenient to lubricate the next time it is used. When the extrusion rod 7 repeatedly operates inside the extrusion tube 6, the extrusion tube 6 is fixed by the support block 23 to ensure that the extrusion tube 6 will not be displaced.

[0030] During testing, the test board 20 is pressed against the ICT surface above the placement stage 21 to test the circuit. The operation of the test board 20 and the placement stage 21 is supported by the support rod 18 and the base 22 to ensure the stability of the test board 20 when testing the ICT above the placement stage 21.

[0031] It should be noted that this device uses the detection plate 20 to press down and drive the pressing rod 9 to squeeze the swing rod 8, so that the swing rod 8 rotates inside the support frame 1 by relying on the reset shaft 12, and the swing rod 8 squeezes the pressing rod 7, which squeezes the lubricating oil inside the pressing tube 6 into the sliding groove 2 along the connector 5 and the lubrication hole 4, thereby lubricating the sliding block 3 sliding inside the sliding groove 2. This solves the problems of inconvenient operation due to the small gap between the sliding groove 2 and the sliding block 3 when manually lubricating, and the high cost and low reliability of sensor detection, thus improving the convenience of lubrication operation.

[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
