There are two symmetrical grooves 15 on the wall, and movable frames 16 are assembled in the two grooves 15. A positioning rod 17 is installed on the top side of the movable frame 16, and sealing covers 18 are installed on both sides of the movable frame 16. The sealing cover 18 is sleeved on the outer periphery of the second air duct 14, and a spring 19 is installed between the bottom side of the sealing cover 18 and the ventilation box 11. A screw 20 is rotatably installed on the ventilation box 11, and a locking rod 21 is slidingly sleeved on the screw 20. The inner wall of the locking rod 21 is provided with a thread and slides with the screw 20 through the thread; when working, the existing detection device is in the process of performing a through detection on the oil passage 10 of the end plate 8 of the air-conditioning compressor. Because the oil passage 10 is an oblique hole, it is difficult to align the detection tube with the oil passage 10 during the detection. The holes are quickly connected, resulting in poor assembly convenience of the device. By placing the end plate 8 on the first rubber pad 6 of the rotating plate 5, the first rubber plug 7 on the first rubber pad 6 blocks the bottom side of the center hole 9 of the end plate 8. By rotating the end plate 8, the first rubber pad 6 and the rotating plate 5 are driven to rotate, thereby achieving stable rotation of the end plate 8. During the rotation of the end plate 8, the positioning rod 17 is pressed on the bottom end of the end plate 8. When the end plate 8 rotates the oil passage 10 port to above the positioning rod 17, the spring 19 pushes the sealing cover 18 to move vertically upward, and the sealing cover 18 drives the movable frame 16 to move vertically upward. The movable frame 16 drives the positioning rod 17 to move vertically upward, and the positioning rod 17 is stuck in the oil passage 10 port. , which makes the end plate 8 unable to rotate, thereby realizing that the second air duct 14 is opposite to the oil channel 10 port. The second air duct 14 and the oil channel 10 port may not be completely aligned, but the sealing cover 18 covers the oil channel 10 port, so that the sealing cover 18 is in a sealed state. By rotating the locking rod 21, the locking rod 21 rotates on the screw 20, and the locking rod 21 moves upward when it rotates. The locking rod 21 pushes the sealing cover 18 at the oil channel 10 port, thereby locking the position of the sealing cover 18. This structure automatically finds its position by rotating the end plate 8, and is sealed and connected to the oil channel 10 port through the sealing cover 18, thereby realizing a quick connection between the oil channel 10 port and the detection tube, which is conducive to improving the convenience of assembly.

By placing the end plate 8 on the first rubber pad 6 of the rotating plate 5, the first rubber plug 7 on the first rubber pad 6 blocks the bottom side of the center hole 9 of the end plate 8, and then the second air guide pipe 14 is connected to the oil channel 10 through the sealing cover 18, and finally the hydraulic cylinder 23 is operated, and the hydraulic rod 24 drives the fixing frame 2 5 moves vertically downward, the fixing frame 25 drives the pressure plate 26, the second rubber pad 27 and the second rubber plug 28 to move vertically downward, so that the second rubber plug 28 blocks the top of the center hole 9 of the end plate 8, and the air pump 31 is operated to guide the air into the exhaust pipe 30. Then the gas enters the center hole 9 of the end plate 8 from the air inlet hole 29, enters the oil channel 10, and is discharged from the oil channel 10 port, and then enters the second air guide pipe 14. Finally, the second air guide pipe 14 is guided into the first air guide pipe 12. The pressure gauge 13 will monitor the changes in gas pressure in the first air duct 12. The pressure gauge 13 transmits the pressure deformation to the pointer through the elastic deformation of the sensitive element in the gauge, and then the conversion mechanism in the gauge movement transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure. The model of the pressure gauge 13 is Y100. If the oil channel 10 is through, air will circulate, and the gas pressure in the first air duct 12 will change accordingly. By directly observing the scale value pointed by the pointer of the pressure gauge 13, the test results can be obtained intuitively, which is conducive to improving the accuracy of the test.

[0022] Working principle: In the process of conducting through-test on the oil passage 10 of the end plate 8 of the air-conditioning compressor by the existing detection device, since the oil passage 10 is an oblique hole, it is difficult to quickly connect the detection tube to the oil passage 10 hole during the test, resulting in poor assembly convenience of the device. By placing the end plate 8 on the first rubber pad 6 of the rotating plate 5, the first rubber plug 7 on the first rubber pad 6 blocks the bottom side of the center hole 9 of the end plate 8, and by rotating the end plate 8, the first rubber pad 6 and the rotating plate 5 are driven to rotate, thereby achieving stable rotation of the end plate 8. During the rotation of the end plate 8, the positioning rod 17 is pressed against the bottom end of the end plate 8. When the end plate 8 rotates the oil passage 10 port to above the positioning rod 17, the spring 19 pushes the sealing cover 18 to move vertically upward, and the sealing cover 18 drives the moving frame 1 6 moves vertically upward, and the movable frame 16 drives the positioning rod 17 to move vertically upward. The positioning rod 17 is stuck in the oil passage 10 port, so that the end plate 8 cannot rotate, thereby realizing that the second air guide pipe 14 is opposite to the oil passage 10 port. The second air guide pipe 14 and the oil passage 10 port may not be completely aligned, but the sealing cover 18 covers the oil passage 10 port therein, so that the sealing cover 18 is in a sealed state. By rotating the locking rod 21, the locking rod 21 rotates on the screw 20, and the locking rod 21 moves upward when it rotates, and the locking rod 21 pushes the sealing cover 18 at the oil passage 10 port, thereby realizing the locking of the sealing cover 18 position. This structure enables the second air guide pipe 14 to automatically find its position by rotating the end plate 8, and is sealed and connected to the oil passage 10 port through the sealing cover 18, thereby realizing the rapid connection between the oil passage 10 port and the detection tube. The connection is conducive to improving the convenience of assembly; the existing detection device cannot intuitively obtain the detection results during the through-detection of the oil passage 10 of the air-conditioning compressor end plate 8, resulting in low detection accuracy. By placing the end plate 8 on the first rubber pad 6 of the rotating plate 5, the first rubber plug 7 on the first rubber pad 6 blocks the bottom side of the center hole 9 of the end plate 8, and then the second air duct 14 is connected to the oil passage 10 through the sealing cover 18. Finally, the hydraulic cylinder 23 is operated, and the hydraulic rod 24 drives the fixing frame 25 to move vertically downward. The fixing frame 25 drives the pressure plate 26, the second rubber pad 27 and the second rubber plug 28 to move vertically downward, so that the second rubber plug 28 is blocked at the top of the center hole 9 of the end plate 8, and is operated by the air pump 31. The air pump 31 exhausts The gas is guided into the tube 30, and then enters the central hole 9 of the end plate 8 from the air inlet hole 29. After entering the oil channel 10, the gas is discharged from the oil channel 10 port, and then enters the second gas pipe 14. Finally, the second gas pipe 14 is guided into the first gas pipe 12. The pressure gauge 13 monitors the gas pressure changes in the first gas pipe 12. The pressure gauge 13 transmits the pressure deformation to the pointer through the elastic deformation of the sensitive element in the gauge, and then the conversion mechanism of the movement in the gauge causes the pointer to rotate to display the pressure. The model of the pressure gauge 13 is Y100. If the oil channel 10 is through, the air will circulate, and the gas pressure in the first gas pipe 12 will change accordingly. By directly observing the scale value pointed to by the pointer of the pressure gauge 13, the test results can be obtained intuitively, which is conducive to improving the accuracy of the test.
