Description

Technical Field

[0001] This utility model relates to the field of Stormer viscometer technology, and in particular to a calibration structure for a Stormer viscometer. Background Technology

[0002] The Stormer viscometer is a testing instrument used to determine the viscosity of non-Newtonian fluids such as paints and coatings. It mainly relies on the blade rotation speed under constant torque to measure the viscosity and directly converts the result into the industry-standard KU value or g value. The Stormer viscometer needs to be calibrated before use.

[0003] However, the calibration of the Stormer viscometer has the following problems:

[0004] First, when calibrating a Stormer viscometer, the blade is immersed in standard oil for calibration. After calibration, the user will remove the cup containing the standard oil. However, some users may be careless or operate improperly and fail to cover the standard oil, causing dust to settle on the standard oil, which will change the viscosity of the standard oil and affect the subsequent calibration results.

[0005] Secondly, if a device is designed to cover the calibration structure of the Stormer viscometer with standard oil, attention should be paid to the fact that the shelf life of the opened standard oil is six months. After the shelf life expires, how to replace it and whether the replacement is convenient should be considered. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, a calibration structure for a Stormer viscometer is provided.

[0007] The specific technical solution is as follows:

[0008] Design a calibration structure for a Stormer viscometer, including a main body, a top plate, and a lifting device. The top plate is fixedly connected to the top of the main body, and the viscometer body is fixedly connected to one side of the top plate. A movable plate is provided on one side of the top plate. A measuring stage is fixedly connected to the top of the movable plate near the viscometer body. Slider blocks are fixedly connected to both sides of the movable plate and are embedded in the top plate. A base is fixedly connected to the bottom of the main body. The lifting device is fixedly connected to one side of the main body. A limiting member is fixedly connected to the end of the base away from the lifting device and is fixedly connected to the inside of the main body.

[0009] Preferably, the lifting device has a knob on top, and a lead screw is fixedly connected to the bottom of the knob, with the lead screw embedded inside the lifting device.

[0010] Preferably, the lead screw is threadedly connected to the drive block, and the base has a support plate on top, with the drive block fixedly connected to the support plate.

[0011] Preferably, a limiting block is fixedly connected to the end of the tray away from the driving block, and the limiting block is embedded in the limiting member.

[0012] Preferably, a standard cup is provided on the top of the tray, and a fixing block is fixedly connected to the bottom of the standard cup, with the fixing block embedded inside the tray.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] 1. When calibrating the Stormer viscometer before use, pull out the movable plate to expose the standard cup inside the main body. The standard cup contains standard oil. Then, rotate the knob clockwise to move the standard cup upward. After the movement is complete, immerse the viscometer's blade into the standard oil for calibration. After calibration, rotate the knob counterclockwise to move the standard cup back into the main body. Then, push the movable plate back to its original position. The bottom of the movable plate fits against the top of the standard cup to prevent dust from entering. The measuring stage is located on top of the movable plate, which means that this device must be closed before it can be used normally. This effectively avoids dust falling into the standard oil due to poor user habits.

[0015] 2. The standard oil in Kaifeng has a service life of six months. When the standard oil expires, first open the moving plate, then rotate the standard cup upwards out of the main body. Then rotate the standard cup so that the fixing block at the bottom of the standard cup is aligned with the notch of the tray. The standard cup can then be removed, the expired standard oil poured out, and replaced with new Kaifeng standard oil. After that, the standard cup can be reset. This makes the standard oil of this device replaceable and the replacement process is relatively simple. Attached Figure Description

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.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] Reference Figure 1-5 A calibration structure for a Stormer viscometer includes a main body 1, a top plate 2, and a lifting device 4. The top plate 2 is fixedly connected to the top of the main body 1. The viscometer body 3 is fixedly connected to one side of the top plate 2. A movable plate 201 is provided on one side of the top plate 2. A measuring stage 202 is fixedly connected to the top of the movable plate 201 near the viscometer body 3. Slider 203s are fixedly connected to both sides of the movable plate 201 and are embedded in the top plate 2. A base 101 is fixedly connected to the bottom inside the main body 1. The lifting device 4 is fixedly connected to one side outside the main body 1. The base 101 is located away from the lifting device 4. One end is fixedly connected to the limiting member 102, which is fixedly connected to the inside of the main body 1. The viscometer body 3 of this device needs to be connected to an external power supply. The viscometer body 3 is equipped with a control terminal to control various electrical devices and analyze the data of the sensor. The sliders 203 on both sides of the moving plate 201 are embedded in the top plate 2, so that the moving plate 201 can move to open or close. When the moving plate 201 is closed, the measuring stage 202 is located at the bottom of the blade of the viscometer body 3. The cup containing the liquid to be measured can be placed on the measuring stage 202 to perform the measurement.

[0027] Furthermore, the top of the lifting device 4 is provided with a knob 402, and the bottom of the knob 402 is fixedly connected to a lead screw 401. The lead screw 401 is embedded inside the lifting device 4, so that rotating the knob 402 can drive the lead screw 401 to rotate.

[0028] Furthermore, the lead screw 401 is threadedly connected to the drive block 502, and the base 101 has a support plate 5 on its top. The drive block 502 is fixedly connected to the support plate 5, so that when the lead screw 401 rotates, it can drive the support plate 5 to move through the drive block.

[0029] Furthermore, a limiting block 501 is fixedly connected to the end of the pallet 5 away from the drive block 502. The limiting block 501 is embedded in the limiting member 102. The cooperation between the limiting block 501 and the limiting member 102 can prevent the pallet 5 from tilting due to the excessive weight of the standard cup 503 containing standard oil.

[0030] Furthermore, a standard cup 503 is provided on the top of the tray 5, and a fixing block 504 is fixedly connected to the bottom of the standard cup 503. The fixing block 504 is embedded inside the tray 5. By rotating the standard cup 503, the fixing block 504 at the bottom of the standard cup 503 is aligned with the notch of the tray 5, and the standard cup 503 can be removed to replace the standard oil inside.

[0031] Working principle: When the Stormer viscometer needs to be calibrated before use, pull out the movable plate 201 to expose the standard cup 503 inside the main body 1. The standard cup 503 contains standard oil. Then, rotate the knob 402 clockwise to move the standard cup 503 upward. After the movement is complete, the impeller of the viscometer body 3 can be immersed in the standard oil for calibration. After calibration, rotate the knob 402 counterclockwise to move the standard cup 503 back into the main body 1. Then, push the movable plate 201 back to its original position. The bottom of the movable plate 201 fits against the top of the standard cup 503 to prevent dust from entering. The measuring stage 202 is located on top of the movable plate 201. This means that the device can only be used normally after the moving plate 201 is closed. This can effectively prevent the standard oil from falling into the dust due to the user's bad usage habits. The standard oil has a service life of six months. When the standard oil expires, first open the moving plate 201, and then move the standard cup 503 upward out of the main body 1 by rotating it. Then rotate the standard cup 503 so that the fixing block 504 at the bottom of the standard cup 503 is aligned with the notch of the tray 5. The standard cup 503 can then be removed, the expired standard oil can be poured out, and new open standard oil can be replaced. Then the standard cup 503 can be reset. This makes the standard oil of this device replaceable and the replacement process is relatively simple.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
