Description

Technical Field

[0001] The utility model relates to the field of test tube cleaning, in particular to a test tube cleaning device for organic chemical experiments. Background Art

[0002] In organic chemistry experiments, heat-resistant glass is usually used as the material. Its shape is usually round or flat-bottomed and has high corrosion resistance. The test tube needs to be cleaned after use to remove pollutants inside it and avoid cross-contamination and reaction interference, thereby ensuring the accuracy of the experimental results and the safety and hygiene inside the laboratory.

[0003] At present, when cleaning test tubes used in experiments, high-speed water flow is usually used to rinse the test tubes. However, if the water flow is directly shot to the bottom of the test tube, splashing may occur, causing the reagents or cleaning liquid inside the test tube to splash onto the operator or other objects, thereby causing pollution or damage to the objects. Therefore, a test tube cleaning device for organic chemistry experiments is proposed to solve the above problems. Utility Model Content

When the rotating rod 42 rotates, the vertical rod 503 is driven to rotate through the fixedly connected connecting rod 504, and then the cylindrical rod 506 is driven to rotate through the connecting spring 505. The outer walls of the cylindrical rod 506 and the arc rod 509 are adapted to fit together. When the arc rod 509 is pushed away from the hollow water guide rod 2, the cylindrical rod 506 is pushed, and then the cylindrical rod 506 drives the cleaning roller 507 to move to the side away from the hollow water guide rod 2 until the cleaning roller 507 fits against the inner wall of the test tube, so as to clean the inner wall of the test tube. The inner wall of the arc rod 509 opens An arc groove 510 is provided, and an arc connecting plate 511 is slidably connected inside the arc groove 510. There are four telescopic rods 508 and arc rods 509, which are distributed circumferentially on the outer surface of the annular fixed plate 501. The left and right sides of the arc connecting plate 511 slide inside the arc groove 510 of two adjacent arc rods 509 respectively. The arc connecting plate 511 extends from the side away from the arc groove 510 to the outside of the arc groove 510. The left and right sides of the arc connecting plate 511 away from the side of the arc groove 510 are both provided with rounded corners. A push rod 512 is fixedly installed at the bottom of the sliding plate 47 away from the center of the hollow water guide rod 2. A rounded table plate 513 is fixedly installed at the bottom end of the rotating rod 42. The push rod 512 and the arc rod 509 and The arc-shaped connecting plate 511 is adapted to be slidably connected. When the push rod 512 is driven by the sliding plate 47 away from the hollow water-guiding rod 2, the push rod 512 will push the arc-shaped rod 509 and the push rod 512 to move in the direction away from the hollow water-guiding rod 2. At this time, the arc-shaped rod 509 will push the cylindrical rod 506 to move in the direction away from the hollow water-guiding rod 2. The middle of the frustum plate 513 and the cleaning roller 507 are flush. The water flowing downward rapidly inside the water pipe 3 and the hollow water-guiding rod 2 will impact the top of the frustum plate 513, thereby splashing in the horizontal direction away from the center of the frustum plate 513. At this time, the water will impact the surface of the rotating cleaning roller 507, and then the inside of the test tube will be cleaned through the cleaning roller 507.

[0030] Working principle: The operator connects the top of the water pipe 3 to the outlet of the water pump of the cleaning liquid, and then places the test tube to be cleaned inside the cleaning tank 1, and the test tube is located directly below the hollow water guide rod 2, and the cleaning roller 507 is located inside the test tube;

[0031] After that, the operator turns on the water pump to pump the cleaning liquid into the water pipe 3. At this time, the cleaning liquid flows into the hollow water guide rod 2 through the water pipe 3. Then, the water flow pumped into the hollow water guide rod 2 will impact the surface of the turbine 43 and drive the turbine 43 to rotate. The turbine 43 will drive the fixedly connected rotating rod 42 to rotate. At this time, the rotating rod 42 drives the rotating ring 41 to rotate and is connected to the inner wall of the water pipe 3, and the rotating rod 42 drives the frustum plate 513 at the bottom to rotate. At the same time, the rotating rod 42 drives the fixedly connected connecting rod 504 to rotate. The connecting rod 504 drives the fixedly connected vertical rod 503 and the rolling ball 502 to rotate. At this time, the rolling ball 502 is rotationally connected to the bottom of the annular fixed plate 501. When the vertical rod 503 rotates, it drives the connecting spring 505 to rotate. Then, the connecting spring 505 drives the cylindrical rod 506 to rotate, and the cylindrical rod 506 drives the fixedly connected cleaning roller 507 to rotate inside the test tube.

[0032] When the water flows inside the hollow water guide rod 2, since one end of the rotating baffle plate 44 is close to the inner wall of the hollow water guide rod 2 and is rotatably connected to the inner wall of the hollow water guide rod 2, the rotating baffle plate 44 will compress the return spring 1 45 and rotate under the impact of the water flow, and then the water flow will continue to flow downward quickly through the rotating baffle plate 44, and when the rotating baffle plate 44 rotates, it will push the telescopic push rod 46 to move downward. As the telescopic push rod 46 moves downward and approaches the sliding plate 47, the telescopic push rod 46 will push the sliding plate 47 to move in the direction away from the center of the hollow water guide rod 2. At this time, the sliding plate 47 will stretch the return spring 2 49 and drive the fixedly connected push rod 512 to move accordingly, and then the push rod 512 will push the arc rod 509 to move to the side away from the hollow water guide rod 2. At this time, after the arc rod 509 is pushed, the arc connecting plate 511 will slide inside the arc groove 510, and At this time, the arc connecting plate 511 will gradually move in the direction away from the arc groove 510 as the arc rod 509 moves, but at this time the arc connecting plate 511 is always located inside the two adjacent arc grooves 510, and at the same time, the telescopic rod 508 will be stretched and extended as the arc rod 509 moves in the direction away from the hollow water guide rod 2, and the rotating cylindrical rod 506 will be pushed as the arc rod 509 moves in the direction away from the hollow water guide rod 2, so that the cylindrical rod 506 stretches the connecting spring 505 and drives the cleaning roller 507 to move in the direction close to the inner wall of the test tube until the cleaning roller 507 rotates and fits against the inner wall of the test tube, and then the water flow sprayed downward in the water pipe 3 will impact the top of the push rod 512, and under the obstruction of the push rod 512, the water flow will spray toward the cleaning roller 507 and the inner wall of the test tube in the horizontal direction, and the water flow will not directly spray toward the bottom wall of the test tube, and then the cleaning roller 507 and the water flow will flush and clean the inner wall of the test tube.
