Description

Technical Field

[0001] The utility model relates to the technical field of anti-splashing of viscometers, in particular to a rotary viscometer with an anti-splashing protective cover. Background Art

[0002] A rotational viscometer, a key laboratory instrument, is specifically designed to accurately measure the viscosity of substances. Its operating principle is to apply shear forces to a substance through a rotational mechanism, thereby quantifying the viscous resistance exhibited during flow. This instrument plays an indispensable role in various industries, including petrochemicals, food processing, pharmaceutical manufacturing, and cosmetics production, serving as a valuable aid in scientific research and product quality control.

[0003] However, in practical applications, viscometers, particularly those equipped with sealing lids and latches, while effectively sealing the measuring container, also present certain limitations. Specifically, the opening process of such designs is cumbersome and requires multiple steps, which inadvertently increases the operator's workload and prolongs the preparation time for each measurement. This can undoubtedly slow down overall work processes when efficiently processing large numbers of samples or performing frequent measurements.

[0004] Furthermore, frequent opening and closing can wear out the locking mechanism, affecting its sealing performance and even causing damage. Further complicating matters, different brands and models of viscometers on the market often utilize different sealing cap and locking designs, which not only increases user learning costs but also forces companies to stock a variety of spare parts to cope with potential replacement needs.

[0005] While the sealing cover and latch structure play a unique role in viscometer design, in today's modern production environment, where efficiency and convenience are paramount, their inherent operational inconvenience and potential maintenance costs need to be addressed. Therefore, for scenarios requiring rapid response or continuous production, exploring more convenient and durable sealing and opening solutions is particularly urgent. Utility Model Content

[0006] The main purpose of the utility model is to provide a rotational viscometer with a splash-proof protective cover, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A rotary viscometer with a splash-proof protective cover comprises a viscometer chassis, a rotating member, a connecting member, a column, and a placement seat. The rotating member is located at the lower end of the viscometer chassis. The connecting member is installed at the rear end of the viscometer chassis and is connected to the column via the connecting member. The placement seat is installed at the lower end of the column.

[0009] The lower end of the viscometer case is connected to a connecting ring, and the lower end of the connecting ring is provided with a plurality of connecting strips, the inner ends of the connecting strips are connected to docking strips, and the lower end of each docking strip is provided with a splash guard, which covers the opening of the viscometer container to prevent material from splashing;

[0010] An arc-shaped cover is provided at the outer end of the splash shield, and the arc-shaped cover covers the opening of the viscometer container to further prevent material from splashing.

[0011] According to a further optional solution of the present invention, a plurality of connection holes are formed on the end surface of the connecting strip, and docking holes adapted to the connection holes are formed on the docking strip. Bolts are inserted into the connection holes and the docking holes to connect the connecting strip and the docking strip. The relative positions of the docking holes and the connecting holes are adjusted to adjust the sliding length of the docking strip, thereby adjusting the downward movement distance of the splash guard.

[0012] A further optional solution of the present invention is that a non-slip rubber strip is provided at the connection between the connecting strip and the docking strip, each docking strip corresponds to a splash guard and is welded to the splash guard, the splash guard is welded to the arc cover, and the end faces of the connecting strip and the docking strip are designed to be arc-shaped;

[0013] In a further optional solution of the present invention, each of the splash guards is designed in a fan shape, and a plurality of the splash guards are distributed in an annular shape to form a circular ring cover, a rubber strip is provided between two adjacent splash guards, and the splash guards and the docking strip are perpendicular to each other;

[0014] In a further optional solution of the present invention, the arc cover is made of a bendable metal sheet, the cross section of the arc cover is designed in a "C" shape, and a rubber ring is provided on the lower edge of the arc cover, and the rubber ring contacts the outer wall of the viscometer container by bending the arc cover;

[0015] According to a further optional solution of the present invention, a plurality of the splash guards are used individually or in combination to achieve modular distribution for easy later maintenance.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fan-shaped splash guard and circular arrangement of this utility model effectively cover the opening of the viscometer container, preventing splashing of materials during experiments and ensuring safety and accuracy.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0026] Shown here is a design of a rotational viscometer with a splash guard, such as Figures 1 to 4 As shown in the figure, the device includes core components such as the viscometer case 1, rotating member 2, connecting member 3, column 4, and support base 5. The rotating member 2 is securely mounted to the bottom of the viscometer case 1, while the connecting member 3 is strategically positioned at the rear of the case, providing a tight connection to the column 4. The column 4 serves as a supporting structure, with the support base 5 fixed to its bottom, ensuring the stability of the entire device.

[0027] The bottom of the viscometer case 1 is designed with a connecting ring 6, which cleverly incorporates multiple connecting bars 7. The ends of these connecting bars 7 are further connected to docking bars 11, forming a stable support frame. Crucially, each docking bar 11 is fitted with a splash guard 9. These splash guards 9 are fan-shaped and arranged in a ring, forming a circular shield that effectively covers the opening of the viscometer container, preventing splashing of substances during experiments.

[0028] To further enhance splash protection, a curved cover 10 is added to the outside of the splash shield 9. Made from a bendable sheet metal, this curved cover 10 features a unique "C"-shaped cross-section, creating both aesthetics and practicality. A rubber ring is also conveniently attached to the lower edge of the curved cover 10. Simply bending the curved cover 10 allows the rubber ring to fit snugly against the outer wall of the viscometer container, further enhancing splash protection.

[0029] Furthermore, a non-slip rubber strip is specially installed at the junction between the connecting strips 7 and the docking strips 11 to ensure a secure connection. Each docking strip 11 is welded to its corresponding splash guard 9 and curved cover 10. This design not only enhances structural strength but also simplifies installation. Furthermore, the curved end faces of both the connecting strips 7 and the docking strips 11 are not only aesthetically pleasing but also avoid potential safety hazards caused by sharp edges.

[0030] The design also fully considers the convenience of later maintenance. Multiple splash guards 9 can be used individually or in combination, achieving modular distribution. This design not only facilitates the flexible adjustment of the number and position of splash guards 9 according to experimental requirements, but also greatly simplifies the maintenance and replacement process. Example

[0031] This embodiment is consistent with the first embodiment in overall structure and function, but has been further optimized in details. Figures 1 to 4 As shown, the rotational viscometer also includes key components such as the viscometer chassis 1, rotating member 2, connecting member 3, column 4, and base 5. However, in the design of the connecting strip 7, this embodiment adds an innovative element: connecting holes 8. These connecting holes 8 are evenly distributed on the end surface of the connecting strip 7, greatly facilitating subsequent assembly and adjustment.

[0032] At the same time, docking strip 11 also features corresponding docking holes 12 that perfectly match the connection holes 8. By inserting and tightening bolts into these holes, a secure connection between connecting strip 7 and docking strip 11 is easily achieved. Even more ingenious, by adjusting the relative position of docking holes 12 and connection holes 8, the downward movement of docking strip 11 can be further adjusted, thereby precisely controlling the downward movement of splash guard 9. This design not only enhances the flexibility of the device but also makes adjustments during experiments simpler and more intuitive.

[0033] Instructions for Use: Ensure that all components of the rotational viscometer (viscometer case 1, rotating member 2, connector 3, column 4, and stand 5) are fully and securely installed. Check that the splash guard 9 and its accompanying curved cover 10 are intact and that the rubber ring is tightly fitted.

[0034] Secure the connecting strip 7 via its connecting ring 6, designed into the bottom of the viscometer case 1, to ensure a secure connection. Connect the docking strip 11 to the connecting strip 7 using a non-slip rubber strip and, if necessary, bolts (such as the connecting holes 8 and docking holes 12 in Example 2), ensuring a secure connection and adjustable positioning. Install the splash guards 9 below the docking strips 11, ensuring each splash guard 9 is securely fixed in place. Install the curved cover 10, bending its rubber ring to fit snugly against the outer wall of the viscometer container to enhance splash protection.

[0035] Based on experimental requirements, the relative positions of the docking holes 12 and the connection holes 8 (as shown in Example 2) are adjusted to control the downward movement of the docking strip 11, thereby adjusting the downward movement of the splash guard 9 to achieve optimal splash protection. Ensure that all connections are tight and that the splash guard 9 and curved cover 10 completely cover the opening of the viscometer container.

[0036] After the splash-proof structure is installed and adjusted, the substance to be tested is poured into the viscometer container and the rotary viscometer is started to conduct the experiment. During the experiment, pay attention to the splash-proof effect of the splash-proof cover 9 and the arc cover 10 to ensure that no substance splashes.

[0037] Adjustment: After installing the splash guard 9 and curved cover 10, perform preliminary adjustments to ensure all components are secure and not loose. Verify that the splash guard 9 completely covers the viscometer container opening. If necessary, fine-tune the position of the splash guard 9 by adjusting the docking strip 11. Use the connection holes 8 and docking holes 12 for fine adjustments. Insert and tighten the bolts, precisely controlling the downward movement of the docking strip 11 to adjust the downward movement of the splash guard 9. During the adjustment process, ensure that the splash guard 9 is evenly distributed and secure to prevent it from shaking or falling off during the experiment. After the adjustments are completed, conduct a small-scale test experiment to verify that the splash guard 9 and curved cover 10 are providing the desired splash protection. If splashing is still observed or the splash protection is unsatisfactory, fine-tune the splash guard 9 according to the experimental results until satisfactory splash protection is achieved. Record the key steps and parameter settings during the adjustment process for rapid replication and adjustment in subsequent experiments. Summarize adjustment experiences to optimize operational procedures and improve experimental efficiency and accuracy.
