Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubricating oil sampling, and particularly relates to a lubricating oil sampling device. 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, mainly playing roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.
[0003] During the production process of lubricating oil, sampling and testing are required for its quality. The existing sampling and inspection methods all use a sampling tube to conduct sampling and testing from the barrel storing the lubricating oil, and this kind of detection is intermittent. During this process, the sampling tube will extend into the lubricating oil, and lubricating oil will adhere to its outer wall. In the subsequent testing process, the lubricating oil adhering to the outer wall of the sampling tube will be mixed with the lubricating oil produced later, resulting in poor detection effects. In view of this, we propose a lubricating oil sampling device. Content of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0033] The present utility model will be further described below with reference to the embodiments.
[0034] Embodiment: Refer to the attached Figures 1-5As shown in the figure, a lubricating oil sampling device includes a sampling tube 100. A sampling groove is provided in the middle of the sampling tube 100. A moving disk 600 is movably connected inside the sampling tube 100. The moving disk 600 is fixedly connected to the output shaft of an external driving mechanism through a driving rod 300. And a moving ring 400 is sleeved on the outer wall of the sampling tube 100. The moving ring 400 can adjust its position relative to the sampling tube 100 to clean the outer wall of the sampling tube 100. Specifically, in this application, by adjusting the position of the driving rod 300 and using negative pressure, normal sampling of the sampling tube 100 can be achieved. It should be noted that after the subsequent sampling is completed, after squeezing out the lubricating oil in the sampling groove, the lubricating oil can be squeezed out by the provided moving disk 600. And during this process, the provided moving ring 400 can automatically clean the outer wall of the sampling tube 100.
[0035] A contraction opening is provided at the lower end of the sampling tube 100. A disk member 200 is installed on the upper part of the sampling tube 100. The disk member 200 can block the upper end outlet of the sampling groove. A round hole 201 is provided in the middle of the disk member 200. The outer wall of the driving rod 300 is slidably matched with the inner wall of the round hole 201. It should be noted that in this application, the sampling groove above the moving disk 600 is relatively sealed and is in communication with the inside of the piston tube 500. The piston tubes 500 are also provided on both sides of the sampling tube 100. A piston rod 420 is movably connected inside the piston tube 500. The lower end of the piston rod 420 extends out of the end of the piston tube 500 and is fixedly connected to the top surface of the moving ring 400. A communication hole 202 is also provided on the disk member 200. The communication hole 202 is in communication with the sampling groove. The disk member 200 is in communication with the inside of the piston tube 500 through a connecting pipe 510. Specifically, in the sampling link, by fixing the connecting rod 320 to the output shaft of an external hydraulic cylinder, the height of the driving rod 300 can be adjusted, and then the height of the moving disk 600 fixedly connected to the driving rod 300 can be adjusted.
[0036] Specifically, when the provided moving disk 600 moves upward, the negative pressure below the sampling groove can be used to suck the lubricating oil. It should be noted that during use, the depth of the sampling tube 100 inserted into the lubricating oil is relatively large, but it is necessary to ensure that the provided moving ring 400 does not contact the lubricating oil. As the moving disk 600 moves upward, the gas above the corresponding sampling groove will enter the piston tube 500 and drive the provided piston rod 420 to move downward, and the provided moving ring 400 is used to clean the lubricating oil residue on the outer wall of the sampling tube 100.
[0037] When it is about to clean to the end position of the sampling tube 100, the outer wall of the moving disk 600 is in sliding fit with the inner wall of the sampling groove, and a ring A620 is fixedly installed on the top surface of the moving disk 600, and a contact A621 is fixedly installed on the top surface of the ring A620; a lapping ring is fixedly installed on the bottom surface of the disk member 200, and a contact B is arranged at a position corresponding to the contact A621 on the lapping ring. When the contact A621 contacts the contact B, the moving disk 600 stops moving upward, and the corresponding moving ring 400 is at the lowermost position of the sampling tube 100;
[0038] Preferably, it further includes an annular groove 401 opened on the inner wall of the moving ring 400, a ring belt 410 is installed in the annular groove 401, an installation groove 411 is opened on the lower side of the ring belt 410, and an annular belt 412 is arranged in the installation groove 411. When the set moving ring 400 moves to the lowermost position of the sampling tube 100, at this time, the set annular belt 412 will contract, driving the set ring belt 410 to contract to effectively clean the contracted position at the lower end of the sampling tube 100.
[0039] An adhesion layer 610 is arranged on the circumferential outer wall of the bottom surface of the moving disk 600, and an elastic membrane 630 is fixedly connected to the moving disk 600 through the adhesion layer 610; the elastic membrane 630 is a disk structure with a convex lower part, and a cavity is formed between it and the bottom surface of the moving disk 600. An installation plate 310 is fixedly installed at the upper end of the active rod 300, connecting rods 320 are symmetrically arranged on the installation plate 310, the connecting rods 320 are fixedly connected to the output shaft of an external hydraulic cylinder, a hose 330 is arranged above the installation plate 310, and the hose 330 is kept communicated with the output end of an external air cylinder; vertical holes 601 are opened in the middle of the active rod 300 and the moving disk 600. When the external air cylinder operates, it will cause the elastic membrane 630 to collide and contact the inner wall of the sampling groove, and completely squeeze out the lubricating oil in the sampling groove. Specifically, in this application, an elastic membrane 630 is arranged at the lower end position of the moving disk 600. When the moving disk 600 moves downward, it will squeeze out the lubricating oil in the sampling tube 100. When the moving disk 600 moves to the lowermost position, for the cleaning of the lubricating oil residue at the contraction port position at the lower end of the sampling tube 100, in this application, gas is injected into the vertical hole 601 through an external air cylinder, so that the elastic membrane 630 expands, and then the elastic membrane 630 can be attached to the inner wall of the sampling groove in the middle of the sampling tube 100, so as to ensure that the lubricating oil can be completely squeezed out, improve the use effect of the sampling tube 100, and at the same time avoid the problem of mixing of lubricating oils in different samplings.
[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
