Description

Technical Field

[0001] The utility model is applicable to the technical field of lubricating oil production, and particularly relates to a device for sampling and testing the viscosity of lubricating oil. Background Art

[0002] At present, lubricating oil mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. It 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. Therefore, its viscosity is particularly important during use, and its viscosity needs to be tested during the production process.

[0003] However, nowadays, when testing the viscosity of lubricating oil, it is often necessary to place it inside a water bath and heat the lubricating oil in a water bath to prevent the lubricating oil from solidifying and affecting the accuracy of the test results. When placing the viscosity tube containing the lubricating oil to be tested inside the water bath for testing and heating, the viscosity tube is installed at the tube mouth only by relying on the rubber pad inside the water bath lid. This installation method is very likely to cause the viscosity tube to fall off from the top of the lid when the tester performs the suction operation on the viscosity tube, affecting the viscosity tube's detection accuracy of the lubricating oil. Therefore, we propose a viscosity sampling device for lubricating oil. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for sampling the viscosity of lubricating oil, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device for sampling viscosity of lubricating oil, comprising a heating pot body, a pot cover detachably mounted on the top of the heating pot body by bolts, mounting grooves are vertically opened on both sides of the pot cover, a liquid injection pipe is movably inserted into the inner side of each mounting groove, a viscosity pipe is fixedly connected to the bottom of the liquid injection pipe, a connecting elbow is fixedly connected to the side of the viscosity pipe, and a liquid storage pipe is fixedly connected to the side of the connecting elbow;

[0007] Each of the mounting grooves has an inner wall movably mounted with a fitting arc plate, and a non-slip friction pad is fixedly bonded to a surface of one side of each fitting arc plate close to the liquid injection tube, and a transmission block is vertically fixedly mounted on the middle surface of the top of each fitting arc plate, and a fixed sleeve is fixedly sleeved on the outer surface of the middle end of each transmission block, and a transmission frame is fixedly mounted between the outer sides of the two groups of fixed sleeves, and the transmission frame is movably mounted on the outer side of the pot cover;

[0008] A fixing plate is fixedly installed on the side surface of the top of the pot cover, an adjusting bolt is detachably installed inside the middle end of the fixing plate through a thread, and the side of the adjusting bolt is rotatably inserted into the side of the transmission frame through a bearing.

[0009] By adopting the above technical solution, through the transmission action of the transmission frame and the screwing action of the adjusting bolt, the fitting arc plate can be moved horizontally synchronously and in the same direction until the outer side of the fitting arc plate fits against the outer wall of the injection tube and limits its movement inside the installation groove, which makes it convenient for the inspection personnel to install and use the viscosity tube and avoids the viscosity tube from being detached arbitrarily during inspection and use, thereby affecting the inspection accuracy.

[0010] As an optional solution of the technical solution of the present application, a connecting frame is movably inserted in the middle of the top of the pot cover, a carrying frame is fixedly installed on the top surface of the connecting frame, and the carrying frame is located on the outside of the pot cover, and an insulation board is vertically fixedly installed on the bottom surface of the connecting frame, and the insulation board is movably installed inside the heating pot body.

[0011] By adopting the above technical solution, the two sides inside the pot cover can be thermally isolated and separated by the thermal insulation effect of the thermal insulation plate.

[0012] As an optional solution of the technical solution of the present application, a sliding groove is opened at the middle end of the top of the pot cover, and the connecting frame is slidably inserted into the sliding groove.

[0013] By adopting the above technical solution, the vertical movement stability of the insulation board is ensured by the guiding sliding action of the sliding groove on the connecting frame.

[0014] As an optional solution of the technical solution of the present application, installation frames are fixedly installed on both sides of the interior of the heating pot body, and the insulation plate is slidably inserted between the interiors of the installation frames.

[0015] By adopting the above technical solution, the structural function of the installation frame can provide the required stability for the installation of the insulation board.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a device for sampling viscosity of lubricating oil, which connects the transmission frame and two groups of fitting arc plates located on the outside of the pot cover through a fixed sleeve and a transmission block, so that when the operator needs to plug and test the two groups of liquid injection tubes, he only needs to twist the adjusting bolt to provide the transmission frame with a corresponding driving force, and then the two groups of fitting arc plates are driven by the transmission action of the transmission frame to have a corresponding driving force, so that the fitting arc plates can be moved horizontally synchronously and in the same direction until the outer side of the fitting arc plate fits against the outer wall of the liquid injection tube and limits its movement inside the installation groove, which is convenient for the inspection personnel to install and use the viscosity tube and avoids the viscosity tube from being arbitrarily separated during inspection and use, thereby affecting the inspection accuracy.

[0018] 2. The technical solution of the present application is a device for sampling viscosity of lubricating oil. By arranging a temperature insulation plate inside the heating pot body, the two sides of the heating pot body can be isolated and the water bath temperature outside the viscosity tubes on both sides can be isolated and adjusted, so that the same lubricating oil sample can be placed in different temperature environments for viscosity detection, thereby further improving the accuracy of lubricating oil viscosity detection.
