This can prevent the lubricating oil entering the detection cylinder from splashing until the lubricating oil contacts the bottom of the pressure plate. Lubricating oil can no longer be added, so the concentration of the lubricating oil can be tested to improve the detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

The outer thread of the reciprocating screw 9 is installed with a pressure plate 6. The outer ring of the pressure plate 6 fits the inner side of the detection cylinder 1. The bottom of the side of the detection cylinder 1 is plugged and installed with an oil outlet pipe 5. A plurality of symmetrically distributed limiting rods 11 are fixedly installed on the inner side of the detection cylinder 1. The outer ring of the pressure plate 6 is provided with a plurality of symmetrically distributed limiting grooves 61. Each limiting rod 11 is slidably engaged with the inner side of the limiting groove 61. A detection instrument is installed inside the detection cylinder 1.

[0022] When in use, block the oil outlet pipe 5, pour the lubricating oil to be tested into the detection cylinder 1, install the top cover 2, turn on the external power supply, and test the lubricating oil. After the test is completed, start the drive motor 3, and the drive motor 3 drives the center rod 7 to rotate. The center rod 7 drives the reciprocating screw rod 9 to rotate through the connecting rod 71, and then under the action of the limit groove 61 and the limit rod 11, the pressure plate 6 moves downward to open the oil outlet pipe 5. In this way, as the pressure plate 6 continues to descend, the lubricating oil in the detection cylinder 1 can be completely pressed out of the detection cylinder 1, thereby realizing the recovery of the lubricating oil after detection. At the same time, the pressure plate 6 can press out the lubricating oil on the inner wall of the detection cylinder 1 at the same time to avoid waste of lubricating oil. After opening the top cover 2, the equipment can be cleaned. The operation is simple and will not cause waste of lubricating oil.

[0023] As a preferred embodiment, there are multiple connecting rods 71 ​​and they are evenly spaced from top to bottom on the inner side of the inner groove 91 to improve the stability of the connection between the center rod 7 and the reciprocating screw rod 9.

At the same time, the filtered oil can enter the inner groove 91 and then flow downward, and finally flow out from the bottom end of the reciprocating screw 9 into the detection cylinder 1. In this way, the splashing of the lubricating oil in the detection cylinder 1 can be avoided. The external power supply is turned on to test the lubricating oil. The test is completed. Finally, the driving motor 3 is started, and the driving motor 3 drives the center rod 7 to rotate. The center rod 7 drives the reciprocating screw rod 9 to rotate through the connecting rod 71, and then under the action of the limit groove 61 and the limit rod 11, the pressure plate 6 moves downward to open the oil outlet pipe 5.
