Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment, and specifically relates to an Ubbelohde viscometer with multiple measuring positions. Background Technology

[0002] An Ubbelohde viscometer is a glass instrument used to measure the viscosity of liquids. The Ubbelohde viscometer has certain limitations due to the lack of a position adjustment mechanism, making it difficult to perform measurements at different heights or specific locations. For example, it cannot meet the needs of studying viscosity changes at different depths or simulating viscosity measurements under specific environmental conditions. This is because the instrument's design is fixed, and the measurement position cannot be changed.

[0003] Conventional approaches primarily involve ensuring the sample and viscometer are at a constant temperature before measurement, selecting a suitable capillary tube, avoiding air bubbles during operation, and performing multiple measurements to obtain an average value. However, temperature control requires additional thermostat equipment, increasing experimental costs and operational complexity. Selecting a suitable capillary tube necessitates prior knowledge of the liquid's viscosity range; otherwise, multiple replacements may be necessary. While multiple measurements can improve accuracy, they increase sample volume and measurement time, and may introduce new errors due to environmental changes during repeated measurements. Therefore, a new structure is needed to address these technical challenges. Utility Model Content

[0024] Please see Figures 1 to 3 This utility model provides a technical solution: an Ubbelohde viscometer with multiple measurement positions, comprising: a base plate 100, an adjustment assembly 200, and a viscometer assembly. A column 110 is mounted on the upper surface of the base plate 100, and an adjustment assembly 200 for adjusting the measurement points is mounted on the outer surface of the column 110.

The viscometer assembly includes a viscometer body, which is mounted on the lower surface of the adjustment assembly 200 via a connector.

[0025] Please see Figures 1 to 3 As the first embodiment of this utility model: the base plate 100 has a triangular structure, a support foot is installed on the lower surface of the base plate 100, a column 110 is installed at the center of the upper surface of the base plate 100, and an adjusting rack 220 is installed on the digging side surface of the column 110.

[0026] The front surface of the adjusting rack 220 is evenly provided with multiple toothed grooves, the outer surface of the adjusting block 210 is rotatably mounted with a rotating part 230, and the center of the upper surface of the adjusting block 210 is provided with a circular through hole extending downwards.

[0027] The inside of the adjusting block 210 is equipped with a gear via a rotating component 230. The gear meshes with the adjusting rack 220, which is slidably disposed inside the circular through hole of the adjusting block 210.

[0028] A connecting rod 240 is installed at the center of the front surface of the adjusting block 210. An arc plate 270 is installed at the end of the connecting rod 240 away from the adjusting block 210. The connecting component includes a fixing rod 300 and a fixing plate 310. The fixing rod 300 is installed on the side surface of the arc plate 270 away from the connecting rod 240.

[0029] The lower end of the fixing rod 300 is connected to the upper surface of the fixing plate 310. The surface of the fixing plate 310 is evenly provided with multiple fixing holes for fixing the viscometer body. The outer surface of the connecting rod 240 is slidably mounted with a sliding sleeve 250.

[0030] An arc-shaped rod 260 is installed on the outer surface of the sliding sleeve 250. A threaded rod 280 is threaded to the end of the arc-shaped rod 260 away from the sliding sleeve 250. The central axis of the threaded rod 280 is collinear with the central axis of the connecting rod 240. The inner end of the threaded rod 280 does not abut against the inner surface of the arc-shaped plate 270.

[0031] In use, the user first fixes the viscometer assembly to the lower part of the adjusting assembly 200 via the connector. After fixing, the user can rotate the rotating part 230 on the outer surface of the adjusting block 210, causing the rotating part 230 to drive the gear inside the adjusting block 210 to rotate, thereby causing the adjusting block 210 to move up and down along the adjusting rack 220 on the outer surface of the column 110. Then, the user can adjust the up and down position of the viscometer assembly by adjusting the rack 220. After the up and down position of the viscometer assembly is adjusted, the user can rotate the threaded rod 280, causing the threaded rod 280 to rotate, thereby adjusting the position of the viscometer assembly by adjusting the gear. The threaded rod 280 connects to the arc-shaped rod 260 and the sliding sleeve 250, which slides to adjust the horizontal position of the viscometer assembly. After the position of the viscometer assembly is adjusted, it can be used. During use, by adjusting the measuring position, the key parts of each viscometer assembly can be precisely placed in the optimal position in the constant temperature environment. Users can adjust the height of each measuring position according to the temperature distribution in the bath, so that the measuring part of the viscometer is in the area of ​​different experimental requirements. This can ensure that multiple measurands can be measured, thereby improving the accuracy and comparability of experimental data.

[0033] When in use, the viscometer body (the viscometer body is existing technology, and its specific structure and working principle will not be elaborated here; when the fluid is subjected to external force to flow, there is tangential internal friction between the flowing liquid layers. If the liquid is to pass through the tube, some work must be consumed to overcome this flow resistance. At low flow rates, the liquid in the tube moves along a straight line parallel to the tube wall. The liquid closest to the tube wall is actually stationary. The farther away from the tube wall, the greater the flow velocity, thus measuring the high molar mass) is used. Since the first tube 400 and the second tube 410 are connected during use, it is beneficial to form a stable liquid column. During the measurement process, the liquid flows from the first tube 400 into the second tube 410. This interconnected structure allows the liquid to flow smoothly within the tube, avoiding measurement errors caused by unstable liquid flow.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
