DETAILED DESCRIPTION
[0032] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.
[0033] Refer to Figure 1 , Figure 2This utility model provides an embodiment of a chemical measuring instrument rack, including a support frame 1. The support frame 1 is a stable frame structure, roughly rectangular in shape, made of durable metal material, specifically stainless steel, which has excellent strength and corrosion resistance. It can withstand the weight of various chemical measuring instruments placed on the rack, as well as external forces during daily use, without easily deforming or being damaged. A support plate 2 is fixedly connected to the outside of the support frame 1. The support plate 2 is a flat rectangular plate, also made of stainless steel, with a smooth surface and good load-bearing capacity. Multiple iron rods 3 are fixedly connected to the top of the support plate 2. The iron rods 3 are straight cylinders made of high-strength alloy steel, which is not only strong but also has a certain degree of toughness and is not easy to break. The iron rods 3 can stably support various fixed components and other parts connected to them, and can still maintain a good structural state under long-term bearing of instrument weight and operating forces. Fixed components are rotatably connected inside the iron rods 3.
[0034] The fixing assembly includes two connecting rods 4, which are slender rod-shaped structures made of medium carbon steel with good toughness, smooth surface, and good torsional resistance. The connecting rods 4 are externally rotatably connected to the inside of the iron rod 3. One connecting rod 4 is externally fixedly connected to an iron ring 5, which is a ring-shaped structure made of uniformly thick iron wire through bending and welding processes. It is also made of sturdy alloy steel with a rust-proof surface treatment to prevent rusting during use, thus maintaining its appearance and lifespan. The other connecting rod 4 is externally fixedly connected to a flask clamp 6, which resembles a clamp with an adjustable jaw. Its main body consists of two opposing metal plates made of high-hardness stainless steel with a smooth surface and internal anti-slip texture. The connecting rod 4 is externally fixedly connected to a torsion post 19, which is a short cylindrical shape made of... Made of engineering plastic for easy gripping and operation, the surface has an anti-slip texture, making it convenient for users to hold and apply twisting force. The top of the support frame 1 has a strip-shaped groove 7, which is a long strip-shaped recessed structure. A spare support component is slidably connected inside the strip-shaped groove 7. The spare support component includes a sliding frame 8, which has a rectangular frame structure and is made of lightweight and strong aluminum alloy. This ensures structural strength without adding too much weight to the entire display stand. The outside of the sliding frame 8 is slidably connected to the outside of the protective cover 14, which is slidably connected to the top of the base 10. The bottom of the sliding frame 8 is slidably connected to the inside of the strip-shaped groove 7. The outside of the sliding frame 8 has a circular groove 9, which is a regular circular recess with varying diameters. The edge of the groove is used to position and limit the instrument, preventing it from rolling or shifting on the display stand.
[0035] The support frame 1 is externally fixedly connected to a base 10. The base 10 is a thick rectangular plate structure made of sturdy and stable cast iron. The high density of cast iron provides a stable base support for the entire rack, ensuring that the rack can be placed stably on the ground or lab bench after various chemical measuring instruments are placed on it, without easily tipping over. A protective mechanism is fixedly connected to the top of the base 10, including a fixing block 13. The fixing block 13 is a small rectangular block structure made of sturdy cast steel. The bottom of the fixing block 13 is fixedly connected to the top of the base 10. A protective cover 14 is rotatably connected to the outside of the fixing block 13. The protective cover 14 is shaped like a cover, roughly matching the shape of the base 10, possessing sufficient strength to provide protection. The top of the protective cover 14 is fixed... A glass plate 15 is connected to the base 10. The glass plate 15 is made of transparent and hard tempered glass, which further increases the overall strength of the protective cover 14, making it more resistant to external impacts and providing an additional observation window so that the user can clearly see the instruments inside the rack from above, facilitating operation and management. A test tube holder 11 is slidably connected to the top of the base 10. The test tube holder 11 has a multi-layered frame structure and is usually made of stainless steel, which ensures that the test tube bottles 12 can be placed neatly and stably on the test tube holder 11. Multiple test tube bottles 12 are slidably connected inside the test tube holder 11. The test tube bottles 12 are common chemical laboratory glass test tubes with a slender cylindrical appearance. Their mouths and bottoms are generally round, and the wall thickness is moderate, which ensures a certain strength and facilitates observation of the internal solution.
[0036] Reference Figure 3 , Figure 4The iron rod 3 is externally fixedly connected to a tilting mechanism, which includes a fixed post 21. The fixed post 21 is a short cylindrical shape made of high-strength alloy steel. The fixed post 21 is rotatably connected to the outside of the iron rod 3. A pawl 20 is rotatably connected to the outside of the fixed post 21. The pawl 20 is shaped like a metal rod with a hook-like structure and is also made of alloy steel, giving it good wear resistance and strength. The connecting rod 4 is externally fixedly connected to a ratchet 18. The ratchet 18 is a disc-shaped structure with uniform and angled teeth on its outer circumference. It is made of wear-resistant and high-strength copper alloy. The ratchet 18 is externally engaged with the outside of the iron rod 3, and the iron rod 3 is rotatably connected to the ratchet 18. A filter plate 16 is fixedly connected to the top of the support frame 1 on the outside of the wheel 18. The filter plate 16 has a flat structure, which allows some liquids (such as a small amount of solution accidentally spilled during the experiment, wastewater after cleaning the instrument, etc.) to pass through, while blocking some larger solid impurities (such as debris falling from the instrument, residual solid reagents, etc.), thus playing a preliminary filtration role. A water storage box 17 is slidably connected to the bottom of the filter plate 16. The water storage box 17 has a rectangular box structure, and its material can be a plastic material that is resistant to acid and alkali corrosion, such as polypropylene (PP) plastic, which has good chemical stability and can hold liquid waste generated in various chemical experiments without being corroded or damaged. The outside of the water storage box 17 is slidably connected to the inside of the support frame 1.
[0037] Working Principle: First, the operator places the support frame 1 on a stable surface in the laboratory, ensuring that its base 10 is in good contact with the ground for stable support. The metal frame structure of the support frame 1 can withstand the weight of various chemical measuring instruments, ensuring their stability during use. At the top of the support frame 1, the spare support assembly sliding frame 8 can be adjusted in position as needed to accommodate different instruments. The operator positions the required chemical measuring instruments through the circular groove 9 to prevent them from sliding or shifting during use. The design of the iron rod 3 and connecting rod 4 allows the instruments to be securely clamped, ensuring their safety during experiments.
[0038] At the end of the experiment, manually move the pawl 20 and rotate the torsion bar 19 to rotate the connecting rod 4. This allows the waste chemical liquid inside the flask to be poured out without contact with the flask. The liquid flows through the filter plate 16 to the water storage box 17 for unified collection. The filter plate 16 also filters and blocks some lumpy waste, ensuring the safety of the user by preventing contact during pouring. Overall, the workflow of this rack fully considers the actual needs of the laboratory, ensuring the safe, stable, and convenient operation of chemical measuring instruments and providing an efficient and reliable working environment for laboratory personnel.
[0039] 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.
