Description

Technical Field

[0001] This utility model relates to the field of test tube cleaning technology, and in particular to a test tube cleaning device for chemical engineering research. Background Technology

[0002] In chemical engineering research, test tubes are one of the most commonly used basic instruments in the laboratory. They are mainly used to hold, mix, or heat small amounts of chemical reagents for reaction observation, sample analysis, and small-scale experiments.

[0003] Since test tubes may come into contact with various chemical reagents, biological samples, or reaction residues during experiments, if they are not thoroughly cleaned, these residues may cause subsequent complications.

[0004] Cross-contamination during experiments can affect data accuracy and even trigger unexpected reactions. Therefore, test tubes must be cleaned after each experiment to ensure their cleanliness and avoid interference between different reagents.

[0005] Currently, test tube cleaning mainly relies on a combination of soaking and manual scrubbing: during cleaning, the test tubes need to be soaked in a cleaning agent to soften the residue, and then the inner wall is manually scrubbed with a brush. This method is inefficient and cannot meet the needs of processing large batches of test tubes. In addition, during manual cleaning, laboratory personnel are likely to come into contact with residual harmful chemicals, which poses a safety risk. Therefore, a test tube cleaning device for chemical engineering research is proposed to solve the above problems. Utility Model Content

One end of the positioning rod is fixedly connected to a limit plate, and the other end of the positioning rod is fixedly connected to a positioning plate.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the positioning rod is slidably connected to a support rod, and the cross-section of the support rod is "L" shaped.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a test tube cleaning device for chemical engineering research, including a cleaning tank 1. A water inlet pipe 2 is fixedly connected to the inner wall of the cleaning tank 1. A rinsing pipe 3 is threadedly connected to the outer wall of the water inlet pipe 2. External clean water is injected into the interior of the water inlet pipe 2, allowing the clean water to enter the interior of the rinsing pipe 3 through the water inlet pipe 2. The rinsing pipe 3 can be easily disassembled by using a threaded connection to clean the brush 5 on its outer wall. The rinsing pipe 3 has at least three sets of water outlet holes 4 equidistantly opened along its axis. The clean water inside the rinsing pipe 3 will be sprayed out through the water outlet holes 4, thereby rinsing the inner wall of the test tube. The brush 5 is fixedly connected to the outer wall of the rinsing pipe 3. The inner wall of the test tube can be brushed by rotating the sleeve 63 in conjunction with the brush 5. The cleaning tank 1 is equipped with a rinsing mechanism and an adjustment mechanism 8.

[0034] Reference Figures 1-3 The rinsing mechanism includes a drive assembly 6, which includes a collar 61 rotatably connected to the top of the cleaning tank 1. A driven gear 62 is fixedly connected to the outer wall of the collar 61, which drives the collar 61 to rotate on the inner wall of the top of the cleaning tank 1. A sleeve 63 is slidably connected to the inner wall of the collar 61. A cam groove 64 is formed on the outer wall of the sleeve 63. The cam groove 64 is a spiral groove with its ends connected. A ball joint 65 is fixedly connected to the top of the cleaning tank 1. The ball joint 65 is an "L"-shaped rod structure. The end of the ball joint 65 away from the cleaning tank 1 is a hemispherical structure, and the spherical surface of the ball joint 65 fits into the cam groove 64. As the sleeve 63 rotates, the guide of the cam groove 64 and the compression of the ball head rod 65 cause the sleeve 63 to slide back and forth on the inner wall of the collar 61. A motor 66 is fixedly connected to the top of the cleaning tank 1. A rotating shaft 67 is fixedly connected to the output end of the motor 66. The end of the rotating shaft 67 away from the motor 66 extends into the interior of the cleaning tank 1 and is fixedly connected to a drive gear 68 that meshes with the driven gear 62. When the motor 66 is started, the rotating shaft 67 is driven to rotate, which in turn drives the drive gear 68 to rotate. As the drive gear 68 rotates, it can drive the collar 61 to rotate on the inner wall of the top of the cleaning tank 1 in conjunction with the driven gear 62 that meshes with it.

[0035] Reference Figures 2-4The rinsing mechanism also includes a positioning assembly 7, which includes a positioning rod 71. The positioning rod 71 passes through and is slidably connected to the inner wall of the sleeve 63. One end of the positioning rod 71 is fixedly connected to a limiting plate 72, and the other end of the positioning rod 71 is fixedly connected to the positioning plate 73. By pulling the limiting plate 72, the positioning rod 71 can slide on the inner wall of the sleeve 63 and stretch the positioning spring 75. A support rod 74 passes through and is slidably connected to the inner wall of the positioning rod 71. The cross-section of the support rod 74 is "L"-shaped. The "L"-shaped support rod 74 can be used to adjust the position of the spring 75 inverted inside the sleeve 63. The test tube is supported at the bottom. A positioning spring 75 is fitted on the outer wall of the positioning rod 71. One end of the positioning spring 75 is fixedly connected to the outer wall of the limiting plate 72, and the other end of the positioning spring 75 is fixedly connected to the outer wall of the sleeve 63. The positioning plate 73 is an arc-shaped plate structure. The test tube can be fixed inside the sleeve 63 by the arc-shaped positioning plate 73. A rubber pad 76 is fixedly connected to the inner arc surface of the positioning plate 73. The rubber pad 76 on the inner arc surface of the positioning plate 73 can increase the friction between the positioning plate 73 and the outer wall of the test tube, so that the positioning plate 73 can better clamp the test tube.

[0036] Reference Figures 3-4 The adjusting mechanism 8 includes a pin 81, which is slidably connected to the inner wall of the positioning rod 71. One end of the pin 81, away from the support rod 74, is fixedly connected to a limiting block 82 via a limiting plate 72. Pulling the pin 81 through the limiting block 82 moves the pin 81 out of the limiting hole 83. A return spring 84 is sleeved on the outer wall of the pin 81. The pin 81 is slidably connected to the limiting plate 72 at the point where it passes through. One end of the return spring 84 is fixedly connected to the side wall of the limiting block 82. The other end of the return spring 84... One end is fixedly connected to the side wall of the limiting plate 72. The limiting block 82 is pulled by the elasticity of the return spring 84, so that the limiting block 82 pushes the pin 81 to slide and reset on the inner wall of the positioning rod 71. The support rod 74 has at least three sets of limiting holes 83 equidistantly opened along its axial direction on the side near the pin 81. The end of the pin 81 away from the limiting block 82 is attached to the inner wall of the limiting hole 83. The pin 81 and the limiting hole 83 can be used to limit the support rod 74, so that the support rod 74 can be fixed at any height.

[0037] Working principle: In use, first pull the limiting plate 72 to make the positioning rod 71 slide on the inner wall of the sleeve 63 and stretch the positioning spring 75. The sliding of the positioning rod 71 can make the positioning plate 73 fit against the inner wall of the sleeve 63. Then, insert the test tube with the opening facing down into the sleeve 63. At this time, the support rod 74 can lift the test tube. Then release the limiting plate 72. At this time, the elasticity of the positioning spring 75 can pull the limiting plate 72, so that the limiting plate 72 pushes the positioning rod 71. At this time, the positioning rod 71 will slide on the inner wall of the sleeve 63. At the same time, the positioning rod 71 will make the positioning plate 73 press against the outer wall of the test tube. The rubber pad 76 on the inner arc surface of the positioning plate 73 can increase the friction between the positioning plate 73 and the outer wall of the test tube, so that the positioning plate 73 can better hold the test tube.

[0038] Once the positioning plate 73 clamps the test tube inside the sleeve 63, external clean water can be injected into the inlet pipe 2, allowing the clean water to enter the rinsing pipe 3. At this time, the clean water inside the rinsing pipe 3 will spray outward through the outlet hole 4, thus rinsing the inner wall of the test tube. Simultaneously, the motor 66 is started, driving the rotating shaft 67 to rotate. The rotating shaft 67 drives the drive gear 68 to rotate. As the drive gear 68 rotates, it engages with the driven gear 62, which in turn drives the collar 61 to rotate on the top inner wall of the cleaning tank 1. The rotation of the collar 61 drives the sleeve 63 to rotate synchronously. The rotation of the sleeve 63, in turn, drives the test tube clamped by the positioning plate 73 to rotate synchronously. The rotation of the test tube allows the clean water sprayed from the outlet hole 4 to rinse evenly. The inner wall of the test tube is brushed, and the brush 5 on the outer wall of the rinsing tube 3 can also be used to scrub the inner wall of the test tube, further improving the cleaning effect. At the same time, as the sleeve 63 rotates, the cam groove 64 on its outer wall will be squeezed by the ball head rod 65. Under the guidance of the cam groove 64 and the squeezing of the ball head rod 65, the sleeve 63 will slide up and down on the inner wall of the collar 61. While the collar 61 slides up and down, it will drive the test tube held by the positioning plate 73 to slide up and down synchronously. The up and down sliding of the test tube can make the brush 5 scrub its inner wall up and down, so that the brush 5 can more fully rub against the inner wall of the test tube. At the same time, the rinsing with clean water can further improve the cleaning effect of the test tube.

[0039] Pulling the pin 81 by the limiting block 82 will cause the pin 81 to move out of the limiting hole 83. At this time, the pin 81 will release the limitation on the support rod 74, and the support rod 74 can be moved up and down, allowing it to slide up and down on the inner wall of the positioning rod 71. This allows the height of the support rod 74 to be freely adjusted so that the support rod 74 can support test tubes of different lengths, ensuring that all test tubes of different lengths can be rinsed by the brush 5 and clean water. After adjustment, the limiting block 82 is released, and the elasticity of the return spring 84 pulls the limiting block 82, causing the limiting block 82 to push the pin 81. The pin 81 can then be inserted back into the limiting hole 83. At this time, the pin 81 and the limiting hole 83 can be used to limit the support rod 74 again, thus fixing the adjusted position of the support rod 74.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
