Description

Technical Field

[0001] This utility model belongs to the technical field of viscosity measurement equipment, specifically, it relates to a portable viscometer. Background Technology

[0002] Viscosity is an important physical property of fluids, and its measurement results are widely used in production quality control, product development and other scenarios in many industries such as chemical, food, pharmaceutical and petroleum. With the increasing demand for on-site testing and outdoor operations, the application scenarios of portable viscometers are becoming more and more extensive.

[0003] Chinese patent CN220961102U discloses a portable viscometer, including a housing and a measuring base. A movable groove is formed on the upper surface of the measuring base. Two movable plates are slidably connected inside the movable groove. Rubber clamps are fixedly connected to the opposite surfaces of the two movable plates. A bidirectional screw rod is set inside the movable groove, passing through the two movable plates and threadedly connected to the through-hole. Both ends of the bidirectional screw rod pass through the measuring base and are rotatably connected to the through-hole by bearings. However, the viscosity measuring rod is an exposed design, which is prone to collision with external objects and damage during movement or carrying. At the same time, the measuring base, support plate and other components have no folding or disassembly function, the overall volume is fixed, and it occupies a large storage space, making it inconvenient to carry around.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a portable viscometer that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A portable viscometer includes: a base, a housing connected to the top of the base via a lifting adjustment assembly, a viscosity measuring rod connected to the bottom of the housing, and three sets of foldable support assemblies equidistantly distributed at the bottom of the base; the lifting adjustment assembly includes a fixed column and a lifting column, the lifting column being connected to the fixed column via a fixed assembly, a storage box connected to the side wall of the fixed column, the storage box having multiple storage cavities inside, the inner diameter of the storage cavities being the same as the outer diameter of the viscosity measuring rod; and a reinforcing rib connecting the bottom side wall of the fixed column to the top of the base.

[0007] Optionally, the foldable support assembly includes a connecting frame, a support plate, and a limiting frame. Two connecting frames and two support plates are provided. One end of the connecting frame near the center of the base is rotatably connected to the base, and the other end is rotatably connected to the support plate. The limiting frame is located on the outer surface of the two connecting frames.

[0008] Optionally, the longitudinal section of the connecting frame is L-shaped, the support plate is located inside the connecting frame, and the bottom surface of the support plate is flush with the bottom surface of the connecting frame.

[0009] Optionally, the limiting frame is open at the bottom, the side wall of the connecting frame is provided with a sliding groove, and the two sides of the inner wall of the limiting frame are connected with sliders corresponding to the sliding groove.

[0010] Optionally, a drive motor is installed inside the housing, and the output end of the drive motor is connected to a connecting shaft, with the other end of the connecting shaft passing through the bottom end of the housing and threadedly connected to the viscosity measuring rod.

[0011] Optionally, a rubber layer is provided between the inner wall of the storage box and the storage cavity, and a top cover is connected to the top of the storage box.

[0012] Optionally, the fixing component includes fixing bolts and adjusting holes. Multiple adjusting holes are provided and are equidistantly opened on the side wall of the lifting column. The fixing bolts pass through the side wall of the base and are located inside the adjusting holes.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. By setting up three sets of equidistantly distributed foldable support components and a limiting and locking structure, this component adopts a design where the connecting frame and support plate are rotatably connected. With the matching structure of the limiting frame and connecting frame, it can quickly form an equilateral triangle three-point support layout when unfolded. The design of the support plate and the bottom surface of the connecting frame being flush increases the contact area with the ground. Combined with the locking effect of the limiting frame, it effectively prevents the equipment from shaking or tipping over during the measurement process, ensuring the accuracy of viscosity measurement data. When storing, simply release the locking of the limiting frame and rotate the connecting frame in the opposite direction to make the component fit against the bottom of the base, greatly reducing the space occupied by the equipment. With the lightweight structural design, it significantly improves the portability of the equipment, making it flexibly adaptable to various mobile scenarios such as on-site testing and outdoor operations. 2. By setting up a lifting and adjusting structure consisting of a fixed column, a lifting column, and a multi-adjustment hole fixing assembly, the lifting column can slide along the axis of the fixed column. With the help of multiple equidistantly distributed adjustment holes and the insertion and locking design of the fixing bolts, the immersion height of the viscosity measuring rod can be flexibly adjusted according to the height of the container holding the fluid to be tested, adapting to the measurement needs of containers of different specifications and expanding the applicability of the equipment. 3. By setting up a storage box structure with multiple storage cavities and a rubber layer, the measurement accessories can be centrally stored, safely protected, and easily accessed. The storage box has multiple storage cavities that match the outer diameter of the viscosity measuring rod, which can classify and centrally store spare measuring rods and measuring rods that have been disassembled after use, so as to avoid the accessories being scattered and lost. The rubber layer on the inner wall of the storage cavity can form a flexible wrap around the measuring rod, effectively cushioning the vibration generated during the carrying or moving of the equipment, and preventing the measuring rod from shifting or colliding, which could cause wear or damage to the accuracy.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Example 1 Please see Figure 1-8 As shown, this embodiment provides a portable viscometer, including: a base 1, a housing 4 connected to the top of the base 1 via a lifting adjustment assembly, a viscosity measuring rod 5 connected to the bottom of the housing 4, and three sets of foldable support assemblies connected to the bottom of the base 1, the three sets of foldable support assemblies being equidistantly distributed; the lifting adjustment assembly includes a fixed column 2 and a lifting column 3, the lifting column 3 being connected to the fixed column 2 via a fixing assembly, a storage box 6 connected to the side wall of the fixed column 2, the storage box 6 having multiple storage cavities 16 inside, and the inner diameter of the storage cavity 16 being the same as the outer diameter of the viscosity measuring rod 5; a reinforcing rib 8 connecting the bottom side wall of the fixed column 2 and the top of the base 1.

[0020] The base 1 serves as the fundamental load-bearing component of the entire viscometer, providing a stable installation reference for the upper lifting adjustment assembly and the lower support assembly. The lifting adjustment assembly consists of a fixed column 2, a lifting column 3, and a fixing component. The fixed column 2 is vertically connected to the top of the base 1, and the lifting column 3 can slide up and down along the axial direction of the fixed column 2. The fixing component can fix the lifting column 3 at any adjustable height. The housing 4 is connected to the top of the lifting column 3 and moves up and down synchronously with the lifting column 3, thereby adjusting the height of the viscosity measuring rod 5 at the bottom. The viscosity measuring rod 5 is installed at the bottom of the housing 4 and can be adjusted by rotation or immersion. The system senses the viscosity characteristics of the fluid. Three sets of foldable support components are equidistantly distributed at the bottom of the base 1 in an equilateral triangle layout. The components can be folded around the connection point for storage. When unfolded, they form a three-point support structure. When folded, they can fit snugly against the bottom of the base 1, reducing space occupation. The storage box 6 is fixed to the side wall of the fixed column 2 and is used to store spare viscosity measuring rods 5 or measuring rods that have been disassembled after use, realizing centralized storage of measuring accessories. The reinforcing rib 8 adopts a rigid connection structure, with both ends fixed to the bottom side wall of the fixed column 2 and the top of the base 1, respectively, forming a triangular support structure to strengthen the connection strength between the fixed column 2 and the base 1.

[0021] Example 2 Please see Figure 1-8 As shown, in this embodiment, the foldable support assembly includes a connecting frame 11, a support plate 9, and a limiting frame 10. There are two connecting frames 11 and two support plates 9. One end of the connecting frame 11 near the center of the base 1 is rotatably connected to the base 1, and the other end is rotatably connected to the support plate 9. The limiting frame 10 is located on the outer surface of the two connecting frames 11. The longitudinal section of the connecting frame 11 is "L" shaped. The support plate 9 is located inside the connecting frame 11, and the bottom surface of the support plate 9 is flush with the bottom surface of the connecting frame 11. The limiting frame 10 is open at the bottom. The side wall of the connecting frame 11 is provided with a sliding groove 12. The inner walls of the limiting frame 10 are connected to sliders corresponding to the sliding groove 12.

[0022] In use, first slide the sliding sleeve out along the groove 12 to detach it from the connecting frame 11. Then rotate the connecting frame 11 outward. The end of the connecting frame 11 near the center of the base 1 is rotatably connected to the base 1, providing a fulcrum for rotation. Simultaneously, it drives the support plate 9, which is rotatably connected to it, to unfold. When the connecting frame 11 and the support plate 9 rotate to the preset support angle, the sliding blocks on both sides of the inner wall of the limiting frame 10 cooperate with the groove 12 on the side wall of the connecting frame 11 to slide the limiting frame 10 downward to the bottom limiting position. At this time, the limiting frame 10 can limit the movement of the connecting frame 10. Further rotation of the connecting frame 11 and the support plate 9 is controlled to lock the support structure, ensuring the components maintain a stable support posture. The bottom surface of the support plate 9 is flush with the bottom surface of the connecting frame 11, and they both contact the ground to bear the weight of the equipment. After use, the limit frame 10 is slid upward to allow the slider to move away from the limit position along the slide groove 12, releasing the rotation restriction on the connecting frame 11. The connecting frame 11 is rotated inward in the opposite direction, causing the support plate 9 to fold synchronously until the connecting frame 11 and the support plate 9 are completely attached to the bottom of the base 1, completing the storage and significantly reducing the space occupied.

[0023] Example 3 Please see Figure 1-8 As shown, in this embodiment, a drive motor 14 is installed inside the housing 4, and a connecting shaft 13 is connected to the output end of the drive motor 14. The other end of the connecting shaft 13 passes through the bottom end of the housing 4 and is threadedly connected to the viscosity measuring rod 5.

[0024] The front end of the housing 4 is connected to an inspection door, which facilitates the inspection of the inside of the housing 4. The side wall of the housing 4 is also provided with heat dissipation grooves. The drive motor 14 drives the viscosity measuring rod 5 to rotate through the connecting shaft 13, and then senses the viscosity characteristics of the fluid through the rotational resistance.

[0025] A rubber layer 15 is provided between the inner wall of the storage box 6 and the storage cavity 16, and a top cover 7 is connected to the top of the storage box 6. The viscosity measuring rod 5 after use or as a spare can be accurately inserted into the matching storage cavity 16. The rubber layer 15 adheres to the surface of the measuring rod to form a flexible wrap. After closing the top cover 7, a sealed environment is achieved to prevent external impurities and moisture from entering, and at the same time to prevent the measuring rod from shifting or colliding during carrying or moving.

[0026] The fixing assembly includes fixing bolts 17 and adjusting holes 18. Multiple adjusting holes 18 are provided and are equidistantly opened on the side wall of the lifting column 3. The fixing bolts 17 pass through the side wall of the base 1 and are located inside the adjusting holes 18.

[0027] In use, the lifting column 3 is positioned and locked by the insertion and removal of the fixing bolt 17 and the adjustment hole 18. When adjusting the lifting height, first loosen the fixing bolt 17 so that the end of the bolt is disengaged from the current adjustment hole 18, thereby releasing the limit on the lifting column 3. At this time, the lifting column 3 can be pushed to slide along the axis of the fixing column 2 to the target height. After reaching the target height, align the fixing bolt 17 with the corresponding height adjustment hole 18 and tighten it. The end of the bolt is embedded in the adjustment hole 18. The pressing force between the bolt and the hole wall restricts the vertical sliding and circumferential rotation of the lifting column 3, thereby achieving stable fixation of the lifting column 3 and locking the height of the housing 4 and the viscosity measuring rod 5.

[0028] Working principle: Before measurement, three sets of equidistant foldable support components are unfolded. The support angle is locked by the slider of the limiting frame 10 and the connecting frame 11 and the sliding groove 12, forming a stable three-point support structure to ensure measurement stability. The reinforcing rib 8 between the fixed column 2 and the base 1 further strengthens the overall rigidity. During the measurement phase, the lifting assembly is adjusted according to the container height. The fixing bolt 17 is loosened to release the limit, and the lifting column 3 is pushed to slide along the fixing column 2 to the target height. Then, the position is locked by the cooperation of the bolt and the corresponding adjustment hole 18, so as to achieve precise control of the immersion height of the viscosity measuring rod 5. The drive motor 14 inside the housing 4 is started, which drives the measuring rod to rotate through the connecting shaft 13. The positive correlation between the resistance of the fluid to the rotating measuring rod and the viscosity is utilized. The heat dissipation groove of the housing 4 ensures stable operation of the motor, and the maintenance door facilitates maintenance. After measurement, clean and disassemble the measuring rod, place it into the storage cavity 16 of the storage box 6 with the rubber layer 15, and close the top cover 7 to achieve a sealed protection, preventing impurities from entering and collision damage; fold the support component to fit the base 1, greatly reducing the space occupied and making it easy to carry and store. The overall process balances measurement accuracy and portability, and is suitable for use in a variety of scenarios.
