Description

Technical Field

[0001] The utility model relates to the technical field of medical detection experiments, in particular to a stable test tube rack for scientific experiments. Background Art

[0002] Test tube racks are typically made of materials such as plastic, wood, or metal. They typically feature multiple, equally sized holes with diameters slightly larger than the outer diameter of the test tubes to ensure stable placement. Some racks are also designed with an angled design to facilitate viewing of the test tube contents. Additionally, some racks may include additional features such as adjustable height and labeling rails.

[0003] Some existing test tube racks primarily utilize their specific structural design to support and secure test tubes. The size of the holes in the test tube rack matches the outer diameter of the test tube. When a test tube is inserted into a hole, the hole wall exerts a certain amount of friction and support on the test tube, allowing the test tube to stand stably on the test tube rack. However, during an experiment, test tubes of different sizes may need to be frequently replaced. If the test tube rack cannot secure test tubes of various sizes, it will be necessary to constantly search for the right placement, which wastes a lot of time and energy and reduces the overall efficiency of the experiment. Therefore, in response to the above-mentioned problems, a stable test tube rack for scientific experiments is proposed. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3, a stable test tube rack for scientific experiments, including a base 1, the base 1 is in the shape of a rectangular parallelepiped, made of a sturdy plastic material, has a certain weight, and can provide a stable foundation for the entire test tube rack. A plurality of rotating shafts 16 are fixedly connected to the left and right sides of the outside of the base 1. The rotating shaft 16 is a cylindrical metal rod with a smooth surface and high strength. It can withstand the frequent rotation of the rotating card 2 without deformation. The connection between the rotating shaft 16 and the base 1 is very firm to ensure that it will not loosen during use. The external fixed connection of the rotating shaft 16 is a limit ring 8. The limit ring 8 is a circular metal sheet with moderate thickness, which can effectively limit the axial movement of the rotating card 2 and prevent it from slipping off the rotating shaft 16. The external rotation connection of the rotating shaft 16 is connected with a plurality of rotating card plates 2. The rotating card plates 2 can rotate freely around the rotating shaft 16, and the angle can be easily adjusted to accommodate test tubes of different sizes. The front rotating card plate 2 is internally slidably connected to a limit block 4, which cooperates with a clamping rod 7 on the rear rotating card plate 2 to firmly fix the two rotating card plates 2 on the test tube rack;

[0032] The stopper 4 is fixedly connected to a sliding rod 5 on the outside, which slides inside the rotating card 2, thereby moving the stopper 4. The smooth surface of the sliding rod 5 reduces friction, making operation smoother. The sliding rod 5 is also fixedly connected to a pull block 3 on the outside. The pull block 3 has anti-slip grooves on its surface, increasing friction between the finger and the pull block, preventing slipping during operation. A spring 6 is sleeved on the outside of the sliding rod 5. When the pull block 3 is pulled to move the stopper 4, the spring 6 is compressed. When the pull block 3 is released, the elastic force of the spring 6 automatically resets the stopper 4. The rear rotating card 2 is slidably connected to the left and right sides of the rotating card 2, allowing it to slide smoothly outside. The clamping rod 7 cooperates with the stopper 4 to secure the two rotating cards 2 to the test tube rack. A fixing assembly is fixedly connected to the inside of the base 1 to enhance stability. The fixing assembly includes a pad 9, which provides additional support and cushioning for the test tube, reducing the shaking of the test tube in the test tube rack. Springs 10 are fixedly attached to both the front and rear sides of the outer portion of the spacer 9. These thin, highly elastic metal sheets 10 are used to compress the connecting ring 13 against the bottom of the test tube through their elastic deformation, further enhancing the tube's stability. A fixing plate 11 is fixedly attached to the top of the spring 10, and multiple connecting rods 12 are fixedly attached to the outside of the spring 10. These connecting rods 12 connect the spring 10 to the connecting ring 13, enabling them to work together.

[0033] The other end of the connecting rod 12 is fixedly connected to a connecting snap ring 13, which is a circular metal ring with a certain degree of elasticity. The function of the connecting snap ring 13 is to contact the outer wall of the test tube and fix the test tube on the test tube rack through the elastic force of the spring sheet 10. The outside of the gasket 9 is fixedly connected to the outside of the base 1, and the inside of the rotating clamping plate 2 is fixedly connected to the test tube body 14. The test tube body 14 is a cylindrical glass container that is transparent and has a certain thickness. The outer wall of the test tube is smooth and the bottom is a circular plane, which is convenient for placement on the test tube rack. The top of the test tube body 14 is fixedly connected to a rubber cover 15, which is a circular rubber sheet with a certain degree of elasticity. The function of the rubber cover 15 is to seal the test tube to prevent the substance in the test tube from leaking or being contaminated by the outside world;

[0034] Reference Figures 3 and 4 , the left and right sides of the outside of the base 1 are fixedly connected with a connecting frame 17, which is L-shaped and made of a solid metal material. One end is firmly fixed to the side of the base 1 by welding or other means, and the other end is horizontal and is used to connect the fixed shaft 18. The internal rotation of the connecting frame 17 is connected to the fixed shaft 18, which can rotate freely inside the connecting frame 17, providing support for the movement of the rotating plate 19. The outside of the fixed shaft 18 is fixedly connected to the rotating plate 19, and both ends of the fixed shaft 18 are provided with a limiting structure to prevent the axial movement of the rotating plate 19, ensuring that the rotating plate 19 does not slip during the rotation process. The outside of the rotating plate 19 is fixedly connected to the telescopic rod 20, and the rotating plate 19 can rotate around the fixed shaft 18 at a certain angle so as to adjust the position to cooperate with other components to fix the test tube. The external sleeve of the telescopic rod 20 is provided with a spring 21, which is a spiral metal spring with a certain elastic coefficient;

[0035] When the rotating plate 19 rotates or the telescopic rod 20 extends and retracts, the spring 21 will be compressed or stretched accordingly. The outside of the rotating plate 19 is fixedly connected to a clamping rod 22, and the position and angle of the clamping rod 22 are carefully designed to better play its fixing role. The front and rear sides of the outside of the base 1 are slidably connected with a sliding frame 25. The sliding frame 25 is a rectangular frame structure made of plastic material. There is a certain space inside it to accommodate the rubber plate 24. The surface of the sliding frame 25 is smooth, and the color is usually black or white, which is in harmony with the overall style of the test tube rack. The sliding frame 25 can slide back and forth on the outside of the base 1 to adjust the position to place more test tubes. The inside of the sliding frame 25 is fixedly connected to a rubber plate 24. The rubber plate 24 is a rectangular rubber sheet with a certain thickness and elasticity. The surface of the rubber plate 24 has some anti-slip textures to increase the friction with the test tube and prevent the test tube from sliding;

[0036] The exterior of the rubber plate 24 is provided with a plurality of slots 23, which serve to secure the second clamping rod to the sliding frame 25. The exterior of the test tube body 14 contacts the exterior of the engagement clamp ring 13, which is fixedly connected to the exterior of the spacer 9. One end of the second spring 21 is fixedly connected to the exterior of the base 1, and the other end of the second spring 21 is fixedly connected to the exterior of the rotating plate 19.

[0037] Working principle: First, pull the card rod 1 7 to allow the sliding rod 5 to slide inside the rotating card plate 2, and then pull the pulling block 3. Under the action of the pulling block 3, the pulling block 3 can drive the sliding rod 5 to drive the limiting block 4 to slide inside the rotating card plate 2. Under the action of the sliding rod 5, during the sliding process of the sliding rod 5, the limiting block 4 can squeeze the spring 1 6, and then the two rotating card plates 2 can be separated. When the test tube is fixed, the test tube is placed inside the rotating card plate 2. At this time, under the action of the rotating card plate 2, the connecting clamp 13 moves to both sides through the spring sheet 10, and then the connecting clamp 13 can adapt to test tubes of different sizes.

[0038] When more test tubes need to be placed, by pressing the rotating plate 19, under the action of the rotating plate 19, the rotating plate 19 can be squeezed by the spring 21 outside the telescopic rod 20, and then the clamping rod 22 can be disengaged from the clamping groove 23 outside the sliding frame 25, so that the sliding frame 25 can slide outside the base 1. When adjusted to the appropriate position, by loosening the rotating plate 19, the clamping rod 22 outside the rotating plate 19 and the clamping groove 23 are engaged with each other, and then the sliding frame 25 can be extended, and then more test tubes can be placed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
