[0002] Lubricating oil plays a vital role in modern mechanical equipment, especially in high-load, high-speed working environments such as engines, compressors, and gear transmission systems. Lubricating oil not only reduces friction and wear, but also effectively dissipates heat, prevents corrosion and oxidation. As the equipment runs for a longer period of time, the performance of the lubricating oil will gradually deteriorate, which may lead to decreased equipment efficiency, increased faults, and even serious equipment damage. Therefore, regular monitoring and detection of the state of the lubricating oil is a key measure to ensure normal operation of the equipment and extend its service life. The lubricating oil detection method usually requires that the lubricating oil sample be extracted and sent to a laboratory for analysis. In this process, a sampling and detection device is needed to extract the oil into a sampling bottle for subsequent laboratory analysis.

[0003] The existing lubricating oil detection device with sampling structure generally connects a hose to sample the lubricating oil in the oil drum. For example, patent CN218157068U3 discloses a lubricating oil sampling and detection device, which solves the problem of dust falling into the oil drum interface and contaminating the oil quality when the oil drum is opened for sampling and inspection. However, in order to avoid cross-contamination of the oil quality during sampling, the current equipment generally needs to frequently replace new hoses or remove and clean them.

[0040] By designing the baffle connected with the lower wall of the other end of the pressure plate 304, the pressure plate 304 can be pressed when the hose is wound on the outer wall of the oil gun 103, and the baffle can also be closed, avoiding the spread of the wound hose in the horizontal direction, and the other end of the pressure plate 304 is arc-shaped and provided with anti-skid lines, which can make the user more convenient and easy to pry open the pressure plate 304.

[0041] Working principle: the function of the device can be used to realize the sampling of lubricating oil and extract it into the sampling bottle 101, which is convenient for subsequent laboratory detection, etc. By pulling the oil gun 103 to form negative pressure, the lubricating oil is sucked from the hose into the sampling bottle 101. These are all existing technologies, which are mature, and will not be described here. When sampling, the equipment needs to be equipped with a hose, which is generally sleeved on the outer wall of the connecting pipe 2 and needs to completely wrap the pipe 2. We can first press the twist plate 209 with our fingers, so as to rotate the twist plate 209. The twist plate 209 is connected with the screw 207, the threads of the screw 207 and the threads in the inner wall of the fixed nut 206 are staggered, which can drive the screw 207 to move forward and backward, and the outer wall of the screw 207 is sleeved with the connecting ring 204, and the connecting ring 204 is limited by the limiting block 208, which can make the screw 207 move while driving the connecting ring 204 to move. The connecting ring 204 is connected with the fixed ring 202, so as to realize the sliding of the fixed ring 202 in the inner part of the movable ring 203. When the hose needs to be sleeved, we can first rotate the twist plate 209 clockwise, so that the fixed ring 202 will loosen outward, then the hose is sleeved on the outer wall of the connecting pipe 2, and then it is moved counterclockwise, so as to drive the fixed ring 202 to tighten inward. The inner part of the movable ring 203 is provided with a movable hole 205 matched with the outer wall of the fixed ring 202, so that one end of the fixed ring 202 can be drilled out of the movable hole 205, and continue to tighten, so as to complete the fixation of the hose. In the actual use environment, compared with the original nut fixation, it is more convenient to avoid the situation that the staff's hands are stained with lubricating oil or slip when the nut is twisted due to sweating.

[0042] When the lubricating oil sampling is completed, the new hose can be replaced for next use, and the pressing plate 304 can be pried open by finger force, then the hose is wound on the outer wall of the oil gun 103 close to the oil gun block 1, one end of the torsion spring 303 is connected with the inner wall of the oil gun block 1, and the other end is connected with the inner wall of the pressing plate 304, when the pressing plate 304 is pried open, a pressure is given to the torsion spring 303, when the torsion spring 303 is pressed, a same counterforce is given to the pressing plate 304, the pressing plate 304 is pressed downward, after the winding of the hose, the pressing plate 304 can be loosened, the hose is pressed flat, and the winding is completed, so that the device is more convenient when being stored.

[0043] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
