[0014] Furthermore, a connecting pipe is connected between the first cylinder and the second cylinder, and a corrugated pipe is connected between the upper end of the vacuum cleaner air inlet and the outer casing.
[0015] This utility model has the following beneficial effects:
[0016] 1. The present invention proposes a cleaning device for ICT test fixtures. When in use, the starting motor drives the transmission shaft to rotate, and the transmission shaft drives two cams to rotate. This facilitates the up-and-down movement of the fixture body through the first connecting block and the two connecting plates, which helps to shake off the dust and facilitate cleaning. At the same time, the two L-shaped scrapers are brought closer together to concentrate the dust on the fixture body, making it easier for the vacuum cleaner to carry it away through the air inlet, thus completing the dust cleaning.
[0017] 2. The present invention proposes a cleaning device for ICT test fixtures. When the drive shaft rotates, it drives two reciprocating screws to rotate through two belt bodies. The two reciprocating screws drive two fixed blocks to move relative to each other, which facilitates the two L-shaped scrapers to move closer together through the second connecting block, thus concentrating the dust together. At the same time, one of the two fixed blocks will also squeeze the output end of the first cylinder, and through the connecting pipe, the second cylinder will drive the air inlet of the vacuum cleaner to move downward, making it easier to suck away the concentrated dust.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a cleaning device for ICT testing fixtures, comprising a housing 1 and a fixture body 2. The housing 1 has four primary fixing brackets 5 inside, with reciprocating screws 6 rotatably mounted between each pair of primary fixing brackets 5. Each of the two reciprocating screws 6 is threaded with a fixing block 3. The fixture body 2 has secondary fixing protrusions 17 fixed on both sides. Each of the upper ends of the secondary fixing protrusions 17 has an L-shaped scraper 19 slidably mounted. Each of the two L-shaped scrapers 19 has a secondary connecting block 20 fixedly mounted on the side away from each other. The two secondary connecting blocks 20 are slidably engaged with one side of each of the two fixing blocks 3. A drive shaft 12 is rotatably mounted at the lower interior of the housing 1, with two cams 16 fixedly mounted around the drive shaft 12. A secondary cylinder 21 is fixedly mounted at the upper interior of the housing 1, with a vacuum cleaner inlet 11 fixedly mounted at the output end of the secondary cylinder 21. A motor 13 is fixedly mounted on one side of the lower interior of the housing 1, and the output ends of the drive shaft 12 and the motor 13 are connected.
[0027] Specifically, starting the motor 13 drives the transmission shaft 12 to rotate, which in turn drives the two cams 16 to rotate. This facilitates the movement of the first connecting block 15 up and down via the cams 16, which in turn moves the two connecting plates 14 and the fixture body 2 up and down, helping to shake out dust from the gaps for easy cleaning. Rotating the two lead screws moves the two fixed blocks 3 closer together, which in turn moves the two L-shaped scrapers 19 closer together via the two second connecting blocks 20, thus concentrating the dust on the fixture body 2 and allowing it to be carried away through the vacuum cleaner inlet 11. Starting the second cylinder 21 moves the vacuum cleaner inlet 11 downward, which helps to get closer to the dust and carry it away.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Two connecting plates 14 are fixedly installed at the lower end of the fixture body 2. Both connecting plates 14 are slidably installed inside the outer shell 1. A first connecting block 15 is fixedly installed at the lower end of the two connecting plates 14. A pulley is fixedly installed at the far ends of the two reciprocating screws 6. A pulley is fixedly installed at both ends of the drive shaft 12. A belt body 4 is connected between each pair of the four pulleys. Two first fixing protrusions 7 are fixedly installed inside the outer shell 1. Two fixing blocks 3 are slidably installed on the upper ends of the two first fixing protrusions 7. A second fixing frame 18 is fixedly installed on the upper end of one of the two first fixing protrusions 7. A first cylinder 8 is fixedly installed on the upper end of the second fixing frame 18. A connecting pipe 9 is connected between the first cylinder 8 and the second cylinder 21. A corrugated pipe 10 is connected between the upper end of the vacuum cleaner air inlet 11 and the outer shell 1.
[0029] Specifically, starting the motor 13 helps to rotate the transmission shaft 12, providing it with power; the two connecting plates 14 and the first connecting block 15 act as a medium, allowing the cam 16 to move the fixture body 2 up and down, shaking off the dust on the fixture body 2; by connecting the belt body 4 between each of the four pulleys, it is easier to drive the reciprocating screw 6 to rotate through the transmission shaft 12, reducing the number of motors 13 used and lowering production and operating costs; when the fixed block 3 moves, it will cause the output end of the first cylinder 8 to compress, and through the connecting pipe 9, it will cause the output end of the second cylinder 21 to extend and retract, making it easier to push the vacuum cleaner inlet 11 downward, making it easier to carry away the concentrated dust;
[0030] Working principle: When the device is in use, the starter motor 13 drives the drive shaft 12 to rotate, which in turn drives the two cams 16 to rotate. This causes the first connecting block 15, the two connecting plates 14, and the fixture body 2 to move up and down, which helps to shake off the dust. In addition, the drive shaft 12 drives the two reciprocating screws 6 to rotate through the two belt bodies 4. The two reciprocating screws 6 drive the two fixed blocks 3, the second connecting block 20, and the L-shaped scraper 19 to move closer together, which helps to concentrate the dust and make it easier to clean. Furthermore, when the two fixed blocks 3 move, one of the fixed blocks 3 will also drive the output end of the first cylinder 8 to compress, thereby extending the output end of the second cylinder 21 through the connecting pipe 9, which drives the vacuum cleaner inlet 11 to move downward, which helps to clean up the concentrated dust.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
