[0002] In chemical experiments, the role of test tubes is crucial and diverse. Test tubes are one of the most basic reaction containers and are used to conduct various chemical reactions. Test tubes can be placed on a heat source (such as an alcohol lamp or a heating plate) to heat the substance in the test tube to cause a thermal reaction or reach the required reaction temperature. Test tubes are one of the basic tools for conducting chemical reactions, observing experimental phenomena, making quantitative measurements, and handling hazardous substances. Test tubes in chemical experiments need to be cleaned after use to ensure the safety and accuracy of the experiment.

[0003] Many test tubes are used in chemical experiments, and the sizes of these test tubes may vary. Current test tube cleaning equipment can only fix test tubes of one size during use and then clean them. This results in poor adaptability of the cleaning equipment, which cannot adapt to the cleaning needs of test tubes of different sizes, resulting in poor cleaning efficiency of the cleaning equipment. Therefore, improvements are now being made to chemical experiment test tube cleaning equipment. Utility Model Content

[0004] The utility model aims to provide a chemical experiment test tube cleaning device to solve the problem that the existing chemical experiment cleaning devices have poor adaptability during use, resulting in low cleaning efficiency.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 4 The present embodiment provides a chemical experiment test tube cleaning device, comprising a base 1, a column 2 is fixedly connected to the upper side of the base 1, a support assembly 3 is slidably connected to the column 2, and a brush 5 is arranged on the support assembly 3 through a motor 4, and a clamping assembly 6 capable of clamping test tubes of different sizes is arranged at a position below the brush 5 on the column 2;

[0023] The clamping assembly 6 includes a fixing frame 61 fixed to the column 2 through a positioning plate 62. A pair of clamping plates 63 for clamping the test tube are arranged inside the fixing frame 61. The opposite surfaces of the two clamping plates 63 are arranged in a V shape.

[0024] In the utility model, when cleaning the test tube, the two clamps 63 in the fixing frame 61 are first pulled apart, and then the test tube to be cleaned is placed between the two clamps 63 and clamped and fixed by the clamps 63. After the test tube is fixed, the bracket assembly 3 is slid on the column 2, thereby driving the brush 5 on the output end of the motor 4 to descend and move to the inside of the test tube. After that, the motor 4 is started to drive the brush 5 to rotate, the cleaning agent is injected into the test tube, and the inner wall of the test tube is cleaned by the brush 5.

[0025] Specifically, refer to Figure 1 and Figure 2A connecting rod 64 is fixedly connected to the side of the clamping plate 63 opposite to the V-shaped surface. The connecting rod 64 penetrates the fixed frame 61 and is slidably connected to the fixed frame 61. A spring 65 is sleeved on the outside of the connecting rod 64 between the clamping plate 63 and the fixed frame 61. A handle 66 is provided on one end of the connecting rod 64 extending to the outside of the fixed frame 61. The two clamping plates 63 can move closer to or away from each other inside the fixed frame 61 through the connecting rod 64. When using the cleaning equipment to clean the test tube, the handle 66 is pulled outward to make the connecting rod 64 slide on the fixed frame 61 and drive the two clamping plates 63 away from each other, so that the gap between the two clamping plates 63 can allow the test tube to pass through. After the test tube passes through the gap between the two clamping plates 63, the handle 66 is slowly released. Under the elastic force of the spring 65, the two clamping plates 63 move closer to each other, thereby clamping and fixing the test tube.

[0026] Among them, a rubber gasket 67 is arranged on the V-shaped surface of the splint 63, and the gasket 67 is arranged in a V shape. The outer surface of the gasket 67 protrudes outward to form a plurality of anti-slip strips 671. The rubber gasket 67 and the anti-slip strips 61 can greatly increase the friction between the splint 63 and the test tube, so that the test tube can be more fixed when clamped by the splint 63, thereby preventing the test tube from detaching from the splint 63 during the cleaning process.

[0027] Among them, a pair of guide rods 68 are fixedly connected to the positions on both sides of the connecting rod 64 on the splint 63. The guide rods 68 penetrate the fixed frame 61 and are slidably connected to the fixed frame 61. A limited position head is set at one end of the guide rod 68 extending to the outside of the fixed frame 61. The guide rods 68 are used to play an auxiliary guiding role. When the splint 63 is pulled to move by the handle 66, the guide rods 68 can prevent the two ends of the splint 63 from deflecting, ensuring the linear movement of the splint 63, thereby ensuring that the splint 63 can clamp the test tube more stably.

[0028] Specifically, refer to Figure 4 The bracket assembly 3 includes a slide 31 sleeved on the outer surface of the column 2, a bracket plate 32 perpendicular to the column 2 is arranged on the slide 31, and a locking bolt 33 is threadedly connected to the position of the slide 31 opposite to the bracket plate 32. The slide 31 slides on the column 2, thereby driving the motor 4 and the brush 5 on the bracket plate 32 to rise and fall, so that the brush 5 enters the test tube when the test tube is cleaned, and the brush 5 rises and leaves the test tube after the test tube is cleaned.

[0029] Among them, one end of the locking bolt 33 located inside the slide 31 abuts against the outer surface of the column 2, and the brush 5 on the output end of the motor 4 moves up and down above the clamping assembly 6 through the slide 31. When the brush 5 needs to enter the test tube for test tube cleaning, the locking bolt 33 is loosened, and then the slide 31 slides on the column 2 to drive the brush 5 to move. When the locking bolt 33 is tightened, the locking bolt 33 abuts against the column 2, so that the slide 31 is fixed on the column 2, and the brush 5 can be stably located in the test tube.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
