Description

Technical Field

[0001] This utility model relates to the field of density meter technology, and in particular to a counterweight adjustable density meter. Background Technology

[0002] A hydrometer, as an important instrument for measuring liquid density, is widely used in many fields. In chemical production, accurately determining the density of reaction liquids helps control the chemical reaction process and ensure the stability of product quality. In the food and beverage industry, hydrometers can be used to detect the concentration of various beverages, ensuring that products meet quality standards. In laboratory research, the accurate measurement of the density of different solutions is a key link in promoting in-depth scientific research. However, in actual measurement processes, for liquids with different density ranges, it is often necessary to adjust the counterweight of the hydrometer to obtain more accurate measurement results. Traditional hydrometers have many inconveniences in terms of counterweight adjustment. Developing a hydrometer that allows for convenient and rapid counterweight adjustment is of great significance for improving the efficiency and accuracy of density measurement.

[0003] Current hydrometers use a built-in counterweight chamber for counterweight adjustment. Adding or removing a specific weight of filler material, such as small lead pellets, into the chamber changes the hydrometer's own weight, thus achieving counterweight adjustment. Structurally, the counterweight chamber is typically sealed with screws to prevent the filler material from falling out.

[0004] However, existing technologies have the problem of difficulty in quickly disassembling and adjusting the counterweight. In chemical production workshops, different liquid formulations may need to be frequently switched during the production process. The density of each liquid varies greatly, which requires the densitometer to be able to quickly adapt to different density ranges. However, for densitometers with built-in counterweight chambers, each adjustment requires unscrewing the screws to open the counterweight chamber, adding or removing filler, and then retightening the screws. The whole process not only requires tools, but the screws are also prone to stripping during frequent operations, resulting in poor sealing and leakage of filler, which further affects the normal use of the densitometer. Therefore, a counterweight adjustable densitometer is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a counterweight adjustable density meter, which aims to improve the technical problem in the prior art that each time the counterweight is adjusted, the screws must be unscrewed to open the counterweight cavity, and the filler must be added or removed before the screws are tightened again, making it difficult to quickly disassemble and adjust the counterweight.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a counterweight adjustable density meter, including a density meter, a sealing cover provided at the top of the density meter, a counterweight block provided at the top of the sealing cover, a connecting frame fixedly connected to the outer wall of the counterweight block, and a fixing component provided on the outer wall of the sealing cover;

[0007] The fixing component includes a support plate, one side of which is fixedly connected to the outer wall of the sealing cover, and the other side of which is fixedly connected to a connecting column. A sliding plate is slidably connected inside the connecting column, and a locking block is fixedly connected to one side of the sliding plate. A locking groove is provided inside the connecting frame, and the locking block is slidably connected inside the locking groove. A telescopic column is fixedly connected inside the connecting column, and one end of the telescopic column is fixedly connected to the other side of the sliding plate. A spring-loaded component is provided on the outer wall of the telescopic column.

[0008] Optionally, the rebound assembly includes a spring, which is sleeved on the outer wall of the telescopic column, and both ends of the telescopic column are respectively fixedly connected to the connecting column and the inside of the sliding plate;

[0009] Optionally, both the densitometer and the outer wall of the sealing cap are fixedly connected to a fixing block, and multiple fixing blocks are distributed in a ring array on the outer wall of the densitometer and the sealing cap.

[0010] Optionally, one of the plurality of fixed blocks is fixedly connected to one side of a limiting block 1, and another plurality of fixed blocks is fixedly connected to one side of a limiting block 2;

[0011] Optionally, a plurality of connecting blocks are fixedly connected to the outer wall of the densitometer, and the plurality of connecting blocks are evenly distributed in a ring array on the outer wall of the densitometer.

[0012] Optionally, a plurality of connecting blocks 2 are fixedly connected to the outer wall of the sealing cover, and the plurality of connecting blocks 2 are evenly distributed in a ring array on the outer wall of the sealing cover;

[0013] Optionally, both the first limiting block and the second limiting block have limiting grooves inside, and multiple first connecting blocks and second connecting blocks are slidably connected inside the multiple limiting grooves.

[0014] The above-mentioned technical solutions of the adjustable counterweight density meter provided in this embodiment of the utility model have at least one of the following technical effects:

[0015] 1. In this utility model, by aligning the connecting frame with the connecting post on the sealing cover, the connecting post presses against the locking block, causing the locking block to compress the telescopic post and the spring. When the connecting frame is fitted into the appropriate position, the spring rebounds, and the locking block slides into the slot to complete the fixation. When disassembling, pressing the locking block to disengage it from the slot allows the counterweight to be removed. This achieves the effect of quick disassembly and installation of the counterweight, solving the problem that each time the counterweight is adjusted, the screws must be unscrewed to open the counterweight cavity, add or remove the filler, and then retighten the screws, making it difficult to quickly disassemble and adjust the counterweight. This improves the flexibility of the densitometer.

[0016] 2. In this utility model, when assembling the densitometer and the sealing cover, after the two are attached together, the sealing cover is rotated. The connecting block two on the sealing cover is inserted into the limiting groove of the limiting block one of the densitometer, and at the same time, the connecting block one of the densitometer is inserted into the limiting groove of the limiting block two of the sealing cover, thus achieving splicing. When disassembling, the sealing cover can be rotated in the opposite direction. This achieves the effect of quick assembly and disassembly of the densitometer and the sealing cover, solving the problem that in traditional densitometers, the densitometer body and sealing components are fastened by complex bolts or glue during maintenance, and the disassembly process requires professional tools and is prone to damage to the components. This improves the convenience of densitometer maintenance. Attached Figure Description

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] Reference Figures 1-3 An embodiment of this utility model is provided: a counterweight adjustable density meter, including a density meter 1, a sealing cover 2 is provided at the top of the density meter 1, a counterweight block 3 is provided at the top of the sealing cover 2, a connecting frame 4 is fixedly connected to the outer wall of the counterweight block 3, and a fixing component is provided on the outer wall of the sealing cover 2.

[0029] The fixing assembly includes a support plate 5, one side of which is fixedly connected to the outer wall of the sealing cover 2, and the other side of which is fixedly connected to a connecting post 6. A sliding plate 7 is slidably connected inside the connecting post 6, and a locking block 8 is fixedly connected to one side of the sliding plate 7. A locking groove 9 is provided inside the connecting frame 4, and the locking block 8 is slidably connected inside the locking groove 9. During installation, the connecting frame 4 is aligned with the connecting post 6 on the sealing cover 2, so that the connecting post 6 presses against the locking block 8. The locking block 8 will drive the sliding plate 7 to slide along the direction of the connecting post 6. At this time, the sliding plate 7 slides along the connecting post 6 against the elastic force of the spring 11, while compressing the telescopic post 10 and the spring 11. The compression of the spring 11 causes the locking block 8 to retract. When the connecting frame 4 is fully inserted into the appropriate position, the spring 11 loses its external force. The counterweight 3 is pressed down and then quickly rebounds, pushing the slide plate 7 and the locking block 8 into the slot 9, thereby completing the fixed connection between the counterweight 3 and the sealing cover 2. A telescopic column 10 is fixedly connected inside the connecting column 6. One end of the telescopic column 10 is fixedly connected to the other side of the slide plate 7. A rebound component is provided on the outer wall of the telescopic column 10. The rebound component includes a spring 11, which is sleeved on the outer wall of the telescopic column 10. Both ends of the telescopic column 10 are fixedly connected to the connecting column 6 and the slide plate 7, respectively. When disassembling the counterweight 3, the user only needs to press the locking block 8 to disengage it from the slot 9. Due to the interlocking design of the locking block 8 and the slot 9, pressing the locking block 8 can cause the locking block 8 to retract and disengage from the slot 9. After that, the counterweight 3 can be easily removed, improving the disassembly speed and convenience of the counterweight 3.

[0030] Reference Figure 1 , Figure 2 and Figure 4 Both the densitometer 1 and the sealing cover 2 are fixedly connected to the outer walls of the densitometer 1 and the sealing cover 2, and multiple fixing blocks 12 are arranged in a ring array on the outer walls of the densitometer 1 and the sealing cover 2. Each fixing block 12 has a limiting block 14 fixedly connected to one side, and another fixing block 16 fixedly connected to one side. Multiple connecting blocks 13 are fixedly connected to the outer wall of the densitometer 1, and these connecting blocks 13 are evenly distributed in a ring array on the outer wall of the densitometer 1. Multiple connecting blocks 17 are fixedly connected to the outer wall of the sealing cover 2, and these connecting blocks 17 are evenly distributed in a ring array on the outer wall of the sealing cover 2. Both the first connecting block 14 and the second limiting block 16 have limiting grooves 15 inside. Multiple connecting blocks 13 and 2 17 are slidably connected inside the multiple limiting grooves 15. When the sealing cover 2 is rotated, the connecting block 2 17 on the sealing cover 2 aligns with the limiting groove 15 on the second limiting block 16. At the same time, the connecting block 13 on the density meter 1 cooperates with the limiting groove 15 on the first limiting block 14 of the sealing cover 2. In this way, the connecting block 13 is smoothly inserted into the limiting groove 15 of the sealing cover 2, while the connecting block 2 17 is inserted into the limiting groove 15 of the density meter 1, thus realizing the splicing and tight connection of the two.

[0031] Working principle: When adjusting the counterweight 3 during the use of the densitometer 1, firstly, when installing the counterweight 3, align the connecting frame 4 with the connecting post 6 on the sealing cover 2, so that the connecting post 6 presses against the locking block 8, causing the locking block 8 to drive the sliding plate 7 to slide against the elastic force of the spring 11 within the connecting post 6, compressing the telescopic post 10 and the spring 11, causing the locking block 8 to retract. When the connecting frame 4 is fitted into the appropriate position, the locking groove 9 is aligned with the locking block 8, the spring 11 rebounds, pushing the sliding plate 7 and the locking block 8 into the locking groove 9, thus achieving a fixed connection between the counterweight 3 and the sealing cover 2. When disassembling, simply press the locking block 8 again to disengage it from the locking groove 9, and the counterweight 3 can be removed, thereby achieving the effect of quick disassembly and easy adjustment of the counterweight 3.

[0032] When maintenance is required inside the densitometer 1, and the densitometer 1 and sealing cover 2 are assembled, first, the sealing cover 2 and the densitometer 1 are fitted together. Then, the sealing cover 2 is rotated. Since connecting block 13 and connecting block 217 respectively cooperate with the limiting grooves 15 on limiting block 14 and limiting block 216, the connecting block 217 at the corresponding position of the sealing cover 2 is inserted into the limiting groove 15 of the upper limit block 14 of the densitometer 1. At the same time, the connecting block 13 of the densitometer 1 is inserted into the limiting groove 15 of the limiting block 216 of the sealing cover 2, thus realizing the splicing and assembly of the two. When disassembling, simply rotate the sealing cover 2 in the opposite direction. This achieves the effect of quick assembly and easy maintenance of the densitometer 1 and the sealing cover 2.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
