When performing performance testing on the diaphragm air pump, the diaphragm air pump is first placed on top of the concave plate 111. At this time, the diaphragm air pump is inside the two semi-circular clamping plates 1229 and the two second semi-circular clamping plates 12214. Then, the motor 1215 is started. After the motor 1215 starts, it drives the transmission disc 1217 to rotate through the track 1216, which in turn causes the columnar horizontal rotating rod 1218 to rotate. The two gears 1219 on the columnar horizontal rotating rod 1218 rotate accordingly. The gears 1219 mesh with the rack rod 12211, driving the two L-shaped sliding rods 12210 to slide in the second guide groove 113 of the concave plate 111. When the L-shaped sliding rods 12210 move, they pull the V-shaped connecting block 12212, the second semi-circular clamping plate connecting block 12213, and the second semi-circular clamping plate 12214 to move forward. At the same time, the columnar horizontal rotating rod 1218 rotates, driving the shafts at both ends. During the rotation of the rotating shaft of the central rotating block 12113, the outer rotating ring 12116 is driven to rotate on the inner wall of the annular guide plate 1214 via the outer rotating ring connecting rod 12114. The rotation of the outer rotating ring 12116 causes the abutment block 12115 to make a circular motion. The abutment block 12115 slides within the elliptical slide plate 1227, pushing the elliptical slide plate 1227 to move backward. The elliptical slide plate 1227 moves backward via the columnar pusher. The pull rod connecting block 1226 and the columnar push-pull rod 1225 drive the clamping member upright plate 1222 to slide backward in the guide groove 112. When the clamping member upright plate 1222 moves, it drives the semi-circular clamping plate connecting block 1228 and the semi-circular clamping plate 1229 to move backward. In this way, the two semi-circular clamping plates 1229 and the two second semi-circular clamping plates 12214 approach each other, thereby clamping and fixing the diaphragm air pump placed on the top of the concave plate 111. After the diaphragm air pump is fixed, it starts to work. The gas it produces is transmitted through the pump body connector 119. Part of the gas enters the noise tester 28 through the interface 12216 and the third pipe 29. The noise tester 28 tests the noise generated by the gas flow and records the data. Another part of the gas enters the air tightness test chamber 23 through the pump body connector 119 and the valve 118. The air tightness of the diaphragm air pump is tested in the air tightness test chamber 23. The tested gas enters the flow negative pressure test tank 24 through the pipe 26. The flow negative pressure test tank 24 tests the flow rate and negative pressure of the gas. The flow record table 25 records the flow rate data. At the same time, part of the gas in the flow negative pressure test tank 24 re-enters the noise tester 28 through the second pipe 27 for auxiliary noise testing. During the test, the soundproof housing 31 slides on the outside of the guide side plate 115 via the soundproof housing slide rod 32, and moves with the soundproof housing pull rod 33 as the L-shaped slide rod 12210 moves, always enclosing the diaphragm air pump inside, achieving a good sound insulation effect and reducing the interference of external noise on the test results. The control panel 22 is used to control the start and stop of the entire test process and display various test data, so that the operator can keep track of the performance test status of the diaphragm air pump in real time.

[0022] Working principle of the invention: When testing the performance of the diaphragm air pump, the diaphragm air pump is first placed on top of the concave plate 111. At this time, the diaphragm air pump is located inside the two semi-circular clamping plates 1229 and the two second semi-circular clamping plates 12214. Then, the motor 1215 is started. The motor 1215 drives the transmission disc 1217 to rotate through the track 1216, which in turn causes the columnar horizontal rotating rod 1218 to rotate. The two gears 1219 on the columnar horizontal rotating rod 1218 rotate accordingly and mesh with the rack rod 12211, driving the two L-shaped sliding rods 12210 to slide in the second guide groove 113 of the concave plate 111. When the L-shaped sliding rods 12210 move, they pull the V-shaped connecting block 12212 and the second semi-circular clamping plate connecting block. 12213 and the second semi-circular clamping plate 12214 move forward. Simultaneously, the rotation of the columnar horizontal rotating rod 1218 drives the rotation of the two end pivot blocks 12113. During rotation, the pivot blocks 12113, through the outer rotating ring connecting rod 12114, drive the outer rotating ring 12116 to rotate on the inner wall of the annular guide plate 1214. The rotation of the outer rotating ring 12116 causes the abutment block 12115 to perform circular motion. The abutment block 12115 slides within the elliptical slide plate 1227, pushing the elliptical slide plate 1227 to move backward. The elliptical slide plate 1227, through the columnar push-pull rod connecting block 1226 and the columnar push-pull rod 1225, drives the clamping member upright plate 1222 to slide backward within the guide groove 112. The clamping member upright plate 1222 moves... When activated, the semi-circular clamping plate connecting block 1228 and the semi-circular clamping plate 1229 move backward, bringing the two semi-circular clamping plates 1229 and the two second semi-circular clamping plates 12214 closer together, thus clamping and fixing the diaphragm air pump placed on top of the concave plate 111. After fixing the diaphragm air pump, it starts to work, and the gas it generates is transmitted through the pump body connector 119. Part of the gas enters the noise tester 28 through the interface 12216 and the third pipe 29. The noise tester 28 tests the noise generated by the gas flow and records the data. The other part of the gas enters the airtightness test chamber 23 through the pump body connector 119 and the valve 118. The airtightness of the diaphragm air pump is tested in the airtightness test chamber 23. After testing, the gas enters the flow negative pressure test tank 24 through pipe 26. The flow negative pressure test tank 24 tests the flow rate and negative pressure of the gas, and the flow record table 25 records the flow data. At the same time, part of the gas in the flow negative pressure test tank 24 enters the noise tester 28 again through the second pipe 27 for auxiliary noise testing. During the test, the sound insulation shell 31 slides on the outside of the guide side plate 115 through the sound insulation shell slide rod 32, and moves with the movement of the sound insulation shell pull rod 33 along with the movement of the L-shaped slide rod 12210, always enclosing the diaphragm air pump inside, achieving a good sound insulation effect and reducing the interference of external noise on the test results. The control panel 22 is used to control the start and stop of the entire test process and display various test data.
