Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil detection, in particular to a drainage device for lubricating oil detection. Background Art

[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 the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Before each batch of lubricating oil is filled, its quality must be tested. Only lubricating oil that meets the requirements can meet factory standards. Therefore, external drainage devices are introduced, such as the utility model patent with patent publication number CN218327469U. Although these devices can effectively solve the problem of the tested lubricating oil coming into contact with air, thereby improving detection accuracy, these drainage devices still have shortcomings in actual use. First, there is the installation problem of the drainage device. The two vertical pipes take up additional space, which is very limited when connecting to the main pipe. Sufficient space is required for the connection location of the filling line oil outlet pipe, which undoubtedly increases the difficulty of filling. Second, after the tested lubricating oil is removed, a large amount of lubricating oil will still remain in the vertical pipe. If this lubricating oil is stored in the vertical pipe for a long time, it will not only easily adhere to the vertical pipe, but also affect the accuracy of the next lubricating oil test. If this lubricating oil is drained, it will be difficult to fill the bottle and can only be reused at a lower grade, which will invisibly cause unnecessary waste. Utility Model Content

[0019] like Figure 1-5 As shown, in this embodiment, a drainage device for lubricating oil detection includes a main pipe 2 with flanges 1 at both ends, an outer pipe 3 is sleeved on the outer wall of the main pipe 2 at the middle position, and the upper and lower ends of the outer pipe 3 are fixedly connected to the outer wall of the main pipe 2 through a connecting plate 4. A plurality of diversion holes 5 connected to the outer pipe 3 are provided on the main pipe 2 along its circumferential direction, and each diversion hole 5 abuts on the connecting plate 4 of the lower layer. A support plate 6 is fixedly sleeved on the outer wall of the main pipe 2 above the outer pipe 3, and a plurality of guide pipes 7 are evenly spaced along the circumferential direction between the support plate 6 and the upper connecting plate 4. A piston ring 8 movably sleeved on the outer wall of the main pipe 2 is provided in the outer pipe 3, and the outer wall of the piston ring 8 is tightly against the inner wall of the outer pipe 3. Connecting rods 9 are vertically provided on the surface of the piston ring 8 corresponding to the position of each guide pipe 7. The upper ends of the connecting rods 9 are extended into the guide tubes 7 on the corresponding side and pass through the support plate 6, and are respectively connected to the connecting rings 10 arranged on the support plate 6. A limiting flange 11 that is movably connected to the corresponding guide tube 7 is provided on each connecting rod 9. A return spring 12 that is sleeved on the corresponding connecting rod 9 is provided in each guide tube 7. The upper end of the return spring 12 abuts against the bottom of the support plate 6, and its lower end abuts against the limiting flange 11 of the connecting rod 9. Handles 13 are symmetrically provided on the left and right sides of the surface of the connecting ring 10, and locking pieces that cooperate with the connecting ring 10 are respectively provided on the left and right sides of the support plate 6; a sampling tube 14 connected to the lower connecting plate 4 is provided below the outer tube 3, a solenoid valve 15 is provided at the lower end of the sampling tube 14, an exhaust pipe 16 is provided on the side wall of the upper end of the sampling tube 14, and an exhaust valve 17 is provided on the exhaust pipe 16.

[0020] Optionally, the locking member includes a first square hole 18 horizontally penetrating the side wall of the support plate 6, a second square hole 19 is provided on the side wall of the connecting ring 10 corresponding to the position of the first square hole 18, a limiting plate 20 horizontally extends into the first square hole 18 and the second square hole 19 in sequence, a paddle 21 is provided on the outer side of the limiting plate 20 to abut against the outer wall of the support plate 6, a boss 22 is provided on the limiting plate 20 to abut against the outer wall of the connecting ring 10, and a groove 23 is provided on the inner wall of the support plate 6 to cooperate with the boss 22.

[0021] Optionally, a plurality of first sealing rings 24 are provided at intervals on the outer wall of the piston ring 8, and a second sealing ring 25 is provided on the upper portion of the inner wall of the piston ring 8. The first sealing ring 24 and the second sealing ring 25 can improve the sealing performance between the piston ring 8 and the outer tube 3.

[0022] Optionally, a transparent observation window 26 is provided on the side wall of the sampling tube 14. The operator can observe the lubricating oil in the sampling tube 14 in time through the transparent observation window 26 to see whether the sampling amount has been reached.

[0023] During operation, lubricating oil flows into the main tube 2. To test the device, simply press the handles 13 on either side with your fingers and pull upward. The connecting ring 10, through the connecting rods 9, pulls the piston ring 8 upward within the outer tube 3. As the piston ring 8 moves, it shifts from its original position within the diverter holes 5 on the outer wall of the main tube 2. Lubricating oil then flows through the diverter holes 5 into the outer tube 3 and into the sampling tube 14. Excess gas in the sampling tube 14 is discharged through the exhaust valve 17 of the exhaust pipe 16, filling the sampling tube 14 with lubricating oil. The operator monitors the oil level through the transparent observation window 26. When the tube is full, the handles 13 are released. The compressed return springs 12, under their restoring force, push the connecting rod 9 downward via the stop flange 11, thereby returning the piston ring 8 to its original position. As the piston ring 8 returns to its original position, the lubricating oil remaining in the outer tube 3 is squeezed back into the main tube 2 through the diverter holes 5. Finally, the operator controls the solenoid valve 15 to open, draining the measured amount of lubricating oil stored in the sampling tube 14. This rationally designed structure allows for docking with filling equipment within a limited space, eliminating the need for installation space and effectively reducing installation difficulty. Furthermore, it allows for quantitative lubricating oil to be collected for testing, reducing unnecessary waste and preventing lubricating oil residue, ensuring the accuracy of the next test. This solves the problems of the prior art.
