[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. After the production of lubricating oil, testing operations need to be carried out to determine whether the lubricating oil meets the standards and regulations of machine manufacturers and professional institutions.

[0003] A patent with the patent authorization announcement number CN220271219U discloses a lubricating oil moisture tester, including a tester, on which a conductive roller is provided; a loading mechanism, which is fixedly installed at the test end of the tester, and the loading mechanism is used for loading the lubricating oil to be tested. Although the above patent can load the lubricating oil through the loading box, making the measurement not restricted by the environment, there are still deficiencies in actual use. For example, when loading the lubricating oil into the loading box, the lubricating oil is manually injected into the loading box from the through hole. This loading method requires the use of injection tools, which is not convenient for quickly loading the lubricating oil, and during the loading process, it is not convenient to timely observe whether the inside of the loading box is full of lubricating oil, easily resulting in the waste of the lubricating oil overflowing on the surface of the loading box.

[0004] Therefore, there is a particular need for a lubricating oil tester with a quantitative extraction function to solve the problems existing in the prior art. Summary of the Utility Model

[0005] In order to overcome the drawback that in the prior patent, the lubricating oil is manually injected into the loading box from the through hole, this loading method requires the use of injection tools, which is not convenient for quickly loading the lubricating oil, and during the loading process, it is not convenient to timely observe whether the inside of the loading box is full of lubricating oil, easily resulting in the waste of the lubricating oil overflowing on the surface of the loading box, the utility model provides a lubricating oil tester with a quantitative extraction function.

The left side of the housing is connected to symmetrically distributed test probes, and the test probes are located inside the sampling cylinder and pass through the piston plate. The control module is electrically connected to the test probes and the motor. By running the motor, the first gear rotates and meshes with the second gear, thereby causing the second gear to rotate, and the threaded piston rod drives the piston plate to move to the right to extract lubricating oil.

[0007] In addition, particularly preferably, it further comprises a plastic tube. The left side of the sampling cylinder is connected to a plastic tube that can be bent at will.

[0008] In addition, particularly preferably, it further comprises a filter screen. The left end inside the plastic tube is connected to a filter screen for filtering the lubricating oil.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: A lubricating oil tester with a quantitative extraction function, refer to Figures 1-6As shown in the figure, it includes a housing 1, a sampling cylinder 2, scale lines 21, a plastic pipe 3, a filter screen 4, a motor 5, a first gear 6, a second gear 7, a threaded piston rod 8, a piston plate 9, a control module 11, a test probe 10, a handle 12 and a rubber sleeve 13. The left side of the housing 1 is connected to the sampling cylinder 2. The sampling cylinder 2 is made of transparent material, and scale lines 21 are printed on the surface of the sampling cylinder 2. The left side of the sampling cylinder 2 is connected to a plastic pipe 3 that can be bent freely. The plastic pipe 3 is a PVC material telescopic water pipe with the advantages of light weight, flexibility, corrosion resistance, and not easy to age. The left end inside the plastic pipe 3 is connected to a filter screen 4 for filtering lubricating oil. The left side inside the housing 1 is connected to the motor 5 by bolts. The first gear 6 and the second gear 7 are rotatably connected to the left side inside the housing 1, and the first gear 6 meshes with the second gear 7. The output shaft of the motor 5 is fixedly connected to the first gear 6. The threaded piston rod 8 is threadedly connected inside the second gear 7. The left end of the threaded piston rod 8 is connected to the piston plate 9. The piston plate 9 is made of sealed rubber material and has a relatively slow compression stress, which can achieve a good pumping effect. The upper part of the housing 1 is connected to the control module 11 by bolts. The left side of the housing 1 is connected to symmetrically distributed test probes 10. The test probes 10 are located inside the sampling cylinder 2 and pass through the piston plate 9. The control module 11 is electrically connected to the test probes 10 and the motor 5. The right side of the housing 1 is connected to a handle 12 for assisting in holding. The outside of the handle 12 is sleeved with a rubber sleeve 13 for increasing friction. By running the motor 5, the first gear 6 rotates and meshes with the second gear 7, and then the second gear 7 rotates, causing the threaded piston rod 8 to drive the piston plate 9 to move to the right to pump the lubricating oil.

[0023] First, the staff holds the handle 12 with their hand and holds the tester above the oil filling barrel. Then, the plastic pipe 3 is bent to an appropriate angle and inserted into the lubricating oil. Next, the motor 5 and the housing 1 are turned on through the control module 11. The output shaft of the motor 5 rotates to drive the first gear 6 to rotate, making it mesh with the second gear 7 in the forward direction. The rotation of the second gear 7 causes the threaded piston rod 8 to drive the piston plate 9 to move to the right, and then the lubricating oil is pumped into the plastic pipe 3 and the sampling cylinder 2 successively. The filter screen 4 filters the lubricating oil to prevent impurities in the lubricating oil from entering the sampling cylinder 2, thereby improving the purity of the lubricating oil. After the lubricating oil enters the sampling cylinder 2, the test probe 10 starts to test the lubricating oil. During the test, the data is transmitted to the control module 11 for display. During the oil pumping process, the staff reads the liquid level of the lubricating oil in the sampling cylinder 2 through the scale lines 21. When the piston plate 9 moves to the limit to the right, the motor 5 is turned off, so that the sampling cylinder 2 is filled with lubricating oil, thereby achieving the purpose of quickly and quantitatively pumping the lubricating oil and preventing waste of the lubricating oil. When the lubricating oil test is completed, the housing 1 is turned off, and the output shaft of the motor 5 is reversed to make the first gear 6 reverse and mesh with the second gear 7 in the reverse direction. The reverse rotation of the second gear 7 causes the threaded piston rod 8 to drive the piston plate 9 to move to the left, and then the lubricating oil in the sampling cylinder 2 is discharged from the plastic pipe 3.
