After the rubber roller 710 contacts the air-conditioning equipment to be detected, the continuous movement of the movable seat 74 will cause the clamping plate 78 to reversely squeeze the connecting seat 77 and the limit seat 711, slide and compress the inner wall of the accommodating groove 713 in the accommodating frame 76. Spring 712, and then the power-on terminal 75 exceeds the clamping plate 78 and is inserted into the power-on socket of the air-conditioning equipment to be tested, and through the cooperation between the power-on terminal 75 and the externally connected electrical performance test meter, the electrical performance test of the air-conditioning equipment to be tested can be carried out, and the feedback of the electrical signal is detected to see whether the calculation of the current and voltage values ​​is abnormal, and then the electric slider 63 slides toward the middle on the electric slide rail 62, and then drives the moving frame 65, the movable plate 66 and the tripod frame 611 and other equipment to move, and the servo motor 67 drives the small gear 68 to rotate and the large gear 610 meshing with it follows the rotation, and when the large gear 610 rotates, it will drive the rotating shaft 69 and the tripod frame 611 to rotate, and when the tripod frame 611 rotates, it will drive the limit plate 612 to rotate,The limit plate 612 first drives the flow tester 615 to correspond to the position of the air-conditioning equipment to be tested, and the air-conditioning equipment is started to monitor whether the flow loss in the pipeline exceeds 160L / min through the flow tester 615. When the leakage test is completed, the servo motor 67 drives the small gear 68 to rotate and the large gear 610 engaged with it follows the rotation. When the large gear 610 rotates, it drives the rotating shaft 69 and the tripod 611 to rotate. When the tripod 611 rotates, it drives the limit plate 612 to rotate. The limit plate 612 first drives the noise sensor 614 and The air-conditioning equipment to be tested corresponds to the position of the air-conditioning equipment, and the air-conditioning equipment is started. The noise sensor 614 is used to detect whether the noise of the air-conditioning equipment exceeds the standard during operation. When the noise test is completed, the servo motor 67 drives the small gear 68 to rotate and the large gear 610 engaged with it follows the rotation. When the large gear 610 rotates, it will drive the rotating shaft 69 and the tripod 611 to rotate. When the tripod 611 rotates, it will drive the limit plate 612 to rotate. The limit plate 612 first drives the audio capture device 616 to correspond to the position of the air-conditioning equipment to be tested, and the air-conditioning equipment is started. The air conditioner is detected by the audio capture device 616 when it is running, and the sound distribution of different bands is collected, and then the software data is analyzed to see if there is a sudden change in the data, so as to judge whether the howling is qualified. When all the tests are completed, the fixing component 7 is separated from the clamping and fixing state of the device to be tested, and the power terminal 75 is separated from the electrical plug-in state of the device to be tested, and the lifting baffle 8 is raised on the electric lifting frame 9, and the driving motor 52 is started to drive the adjusting screw rod 53 and the toothed belt wheel 57 on the right to rotate, and the toothed belt 58 is driven to drive the adjusting screw rod 53 and the toothed belt wheel 57 on the right to rotate. The toothed belt wheel 57 and the adjusting screw 53 on the left side are driven to rotate synchronously at the same speed. The screw threads of the adjusting screws 53 on the left and right sides are in the same direction. When the adjusting screw 53 rotates, it drives the sliding block 54 to drive the silent door 56 to move linearly along the outer wall of the adjusting screw 53, and then the silent door 56 is separated from the through-port 55. Then, the equipment after the inspection is completed is transported to the U-shaped baffle 21 through the transmission roller 22 and the transmission belt 23, and then the work is stopped. The U-shaped baffle 21 can block the equipment after the inspection is completed, and the staff can take out the equipment after the inspection.
