[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 workpieces. Its primary functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and cushioning. In actual lubricating oil use, it is necessary to regularly extract samples from the lubricating oil processing pipeline and subsequently test the batch of lubricating oil to prevent substandard lubricating oil from being put into use.
[0003] The sampling device for lubricating oil processing pipelines in the prior art usually extracts samples into the interior of the device. However, when the lubricating oil processing pipeline is extracted multiple times, samples from different batches remain on the inner wall of the device, causing the different batches of samples to mix, thereby affecting the subsequent detection and identification of the samples, which is not conducive to the production of high-quality lubricating oil.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: through the setting of the sealing cover, the sealing cover is first rotated to make the block slide out of the groove of the rotating slot, and then the sealing cover can be pulled upward to remove the sealing cover from the top of the rotating slot. At this time, a disposable sampling tube for isolating the lubricating oil from the inner wall of the sampling barrel can be placed into the sampling barrel.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a sampling device for a lubricating oil processing pipeline, comprising a sampling barrel 1, a threaded connecting tube 2 fixedly connected to the bottom of the sampling barrel 1, a rotating connecting tube 3 fixedly connected to the top of the sampling barrel 1, a rotating slot 4 is provided on both sides of the rotating connecting tube 3, a sealing cover 5 is slidably connected to the outer wall of the rotating connecting tube 3, a clamping block 6 is fixedly connected to the inner wall of the sealing cover 5, the clamping block 6 is slidably connected to the rotating slot 4, a disposable sampling tube 7 is slidably connected to the inner wall of the sampling barrel 1, a feeding tube 8 is fixedly connected to the bottom of the disposable sampling tube 7, and the feeding tube 8 is slidably connected to the inner wall of the threaded connecting tube 2.
[0022] In an optional embodiment, the outer wall of the threaded connection tube 2 is threadedly connected to a rotary connection sleeve 9 , the bottom of the rotary connection sleeve 9 is fixedly connected to a fixing cap 10 , and the bottom of the fixing cap 10 is fixedly connected to a sampling tube head 11 .
[0023] It should be noted that when using the device for sampling, first rotate the sealing cover 5 so that the block 6 slides out of the groove of the rotating slot 4, and then pull the sealing cover 5 upward to remove the sealing cover 5 from the top of the rotating slot 4. At this time, a disposable sampling tube 7 for isolating the lubricating oil from the inner wall of the sampling cylinder 1 can be inserted into the sampling cylinder 1. When the disposable sampling tube 7 slides to the bottom of the sampling cylinder 1 and the feed tube 8 enters the threaded connecting tube 2, the sealing cover 5 can be reset and tightened in reverse so that the block 6 enters the groove of the rotating slot 4, thereby achieving the effect of quickly fixing the sealing cover 5, so that the disposable sampling tube 7 for isolating the lubricating oil from the inner wall of the sampling cylinder 1 can be quickly replaced, thereby ensuring that the samples taken will not interfere with each other during multiple samplings.
[0024] In an optional embodiment: the top of the sealing cover 5 is fixedly connected to a fixed seat 12, the middle of the fixed seat 12 is slidably connected to a sliding rod 13, the sliding rod 13 is fixedly connected to a fixing buckle 14 on the outer wall below the sealing cover 5, the top of the fixing buckle 14 is fixedly connected to a spring 15, the bottom of the sliding rod 13 is fixedly connected to a piston head 16, the piston head 16 is slidably connected to the inner wall of the disposable sampling tube 7, the top of the sliding rod 13 is fixedly connected to a fixed handle 17, the top of the sampling cylinder 1 is fixedly connected to a fixing ring 18, and an exhaust hole 19 is provided inside the fixing ring 18.
[0025] It should be noted that when the disposable sampling tube 7 is installed inside the sampling cylinder 1 and the sealing cover 5 is fully installed, the fixed handle 17 is used to drive the sliding rod 13, so that the interior of the disposable sampling tube 7 can generate negative pressure under the action of the piston head 16, so that the sampling tube head 11 inserted into the lubricating oil to be sampled can suck the sample into the interior of the disposable sampling tube 7. When the piston head 16 moves upward, the air can be discharged through the exhaust hole 19, thereby ensuring that the fixed handle 17 can be pulled normally. In the intervals between multiple samplings, the rotating connecting sleeve 9 can be unscrewed to clean or replace the sampling tube head 11, so that interference between samples of multiple samplings can be avoided, thereby improving the quality of the sample.
[0026] In an optional embodiment, a scale line 20 is provided on the side of the sampling cylinder 1 , and a hand-held block 21 is fixedly mounted on the outer wall of the sampling cylinder 1 .
[0027] It should be noted that the volume of lubricating oil extracted from the disposable sampling tube 7 can be observed through the scale line 20, so as to accurately control the demand for sample extraction.
