Description

Technical Field

[0001] This utility model relates to the field of liquid viscosity detection technology, specifically to an oil viscosity detector. Background Technology

[0002] An oil viscosity meter is a professional instrument used to measure the viscosity of fluids, especially oils. Its working principle is based on the viscous resistance characteristics in fluid mechanics. It measures viscosity by measuring the resistance torque experienced by the rotor when rotating in the oil, which is proportional to the viscosity.

[0003] Chinese Patent Publication No. CN220380950U discloses an oil viscosity testing device, including a base plate. A protrusion is fixed to the outer arc surface of the base plate, and a support rod is fixed to the top of the protrusion. A groove is formed on the surface of the support rod, and a one-way screw is rotatably mounted on the inner wall of the top of the groove. A lifting block is sleeved on and threadedly connected to the surface of the one-way screw. A detector is fixed to one end of the lifting block, and a disc is fixed to the bottom of the detector. A sealing gasket is fixed to the bottom of the disc. In this invention, a first motor drives the one-way screw to rotate, which in turn lowers the lifting block, causing the detector to descend. This ensures that the sealing gasket at the bottom of the disc is tightly pressed against the top of the container, preventing external dust particles from entering the container and also preventing oil from splashing out during the rotating testing process.

[0004] In the aforementioned prior art, a sealing gasket can be used to seal the container containing the oil sample, and the viscosity testing device can be controlled to descend into the oil to perform viscosity testing. In order to ensure the accuracy of the test results, it is usually necessary to prepare multiple sets of samples with different temperatures or different additives for testing. However, the container used to hold the sample can only hold one set of samples at a time, which requires the staff to frequently change the samples, which is time-consuming and prone to errors. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an oil viscosity detector that solves the problem mentioned in the background art where the sample container of the oil viscosity detector can only hold one set of samples at a time, resulting in the need for staff to frequently change samples for testing, which is time-consuming and prone to errors.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1:

[0047] like Figures 1 to 6 As shown, this utility model provides an oil viscosity detector, including: a viscosity meter 1 and a bracket 2. The viscosity meter 1 is provided with a connecting line 101 and a detection probe 102 is provided on the connecting line 101. It also includes a storage structure arranged on the bracket 2 for storing oil samples.

[0048] The storage structure includes a transparent sample container 201 movably installed inside the support 2, and several partition plates 202 evenly arranged inside the transparent sample container 201 to divide the space inside the transparent sample container 201. By setting several partition plates 202 inside the transparent sample container 201, the interior of the transparent sample container 201 can be divided into several spaces, and different samples can be placed in each space.

[0049] Example 2:

[0050] Based on Example 1, in order to improve the sealing performance when testing oil samples and avoid interference from external impurities, a sealing structure is arranged in the storage structure to prevent impurities from entering the oil.

[0051] The sealing structure includes a sealing cap 3 movably fitted onto the transparent sample container 201, a movable cover plate 301 rotatably installed inside the sealing cap 3 and arranged below the viscometer 1, a fixing ring 302 fixedly fitted onto the transparent sample container 201, a sealing ring 303 arranged above the fixing ring 302, and a compression ring 304 arranged on the inner wall of the sealing cap 3. The compression ring 304 contacts the sealing ring 303. When the sealing cap 3 descends, it covers the transparent sample container 201. At the same time, the sealing cap 3 drives the compression ring 304 to press against the sealing ring 303, thereby improving the sealing performance of the transparent sample container 201.

[0052] The sealing structure also includes a limiting component arranged on the sealing cap 3 for mounting the sealing cap 3 on the transparent sample container 201.

[0053] Furthermore, the limiting component includes several limiting screws 305 that are uniformly threaded inside the sealing cover 3. The limiting screws 305 are located below the fixing ring 302. When the limiting screws 305 rotate, they can move by engaging with the threads of the sealing cover 3, so that the moving sealing cover 3 is blocked below the fixing ring 302, thereby limiting the position of the sealing cover 3.

[0054] Example 3:

[0055] Based on Example 1, in order to facilitate the control of the detection probe 102 to move into different sample oils for detection, an adjustment structure for controlling the movement of the detection probe 102 in different samples is arranged on the detection probe 102. The adjustment structure includes a lifting adjustment component for controlling the lifting and lowering movement of the detection probe 102 and a rotation adjustment component for controlling the rotation of the detection probe 102.

[0056] The lifting and adjusting assembly includes a mounting plate 4 arranged on the detection probe 102 and a multi-stage electric push rod 401 arranged above the movable cover plate 301. The telescopic end of the multi-stage electric push rod 401 passes through the movable cover plate 301 and is arranged above the mounting plate 4. By opening the multi-stage electric push rod 401, its telescopic end can control the mounting plate 4 to move downward, so that the mounting plate 4 drives the detection probe 102 to descend and extend into the corresponding sample.

[0057] The lifting and adjusting assembly also includes a U-shaped frame 402 arranged above the sealing cover 3 and a lifting electric push rod 405 arranged above the bracket 2. The telescopic end of the lifting electric push rod 405 is arranged above the U-shaped frame 402. By opening the lifting electric push rod 405, its telescopic end can drive the U-shaped frame 402 to move up and down, so that the U-shaped frame 402 can drive the sealing cover 3 to move up and down, so as to open or close the transparent sample container 201.

[0058] The rotary adjustment assembly includes a motor 403 arranged above the U-shaped frame 402 and a limiting cover 404 slidably sleeved on the detection probe 102. The limiting cover 404 and the movable cover 301 are both fixedly sleeved on the output end of the motor 403. Turning on the motor 403 can drive the movable cover 301 and the limiting cover 404 to rotate, thereby driving the viscometer 1, the multi-stage electric push rod 401 and the detection probe 102 to rotate accordingly, so that the detection probe 102 can be aligned with another sample.

[0059] Working principle:

[0060] By setting several partition plates 202, the transparent sample container 201 can be divided into several spaces, which can hold samples of different temperatures or containing different additives. Then, the transparent sample container 201 is placed on the support 2. By activating the lifting electric push rod 405, its telescopic end can drive the U-shaped frame 402 to descend, causing the U-shaped frame 402 to drive the sealing cover 3 to descend as well. The descending sealing cover 3 will cover the transparent sample container 201, and at the same time, the sealing cover 3 will cause the compression ring 304 to press tightly against the sealing ring 303, improving the sealing performance of the transparent sample container 201. Then, the surrounding limiting screws 305 are rotated... When the rod 305 rotates, it can move by engaging with the threaded seal 3, so that the moving seal 3 is blocked below the fixing ring 302, thereby restricting the position of the seal 3 and preventing the seal 3 from coming off the transparent sample container 201. At this time, by opening the multi-stage electric push rod 401, its telescopic end can control the mounting plate 4 to move downward, so that the mounting plate 4 drives the detection probe 102 to descend. The end of the descending detection probe 102 will slide inside the limiting cover plate 404 and extend into the corresponding sample. At this time, the viscometer 1 can be used to control the detection probe 102 to perform detection operation on the oil sample.

[0061] After the current sample test is completed, the multi-stage electric push rod 401 can be used to control the detection probe 102 to rise and detach from the corresponding sample. Then, the motor 403 is turned on, and the output of the motor 403 can drive the movable cover plate 301 and the limiting cover plate 404 to rotate. This, in turn, drives the viscometer 1, the multi-stage electric push rod 401 and the detection probe 102 to rotate, controlling the detection probe 102 to be aligned with another sample. Then, the detection probe 102 is controlled to descend again to perform the detection operation. This process can be repeated to achieve continuous detection of different samples. During the detection process, the transparent sample container 201 is always sealed, which can avoid interference from external impurities.

[0062] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
