Description

Technical Field

[0001] The utility model relates to the technical field of chemical analysis, in particular to a rotatable colorimetric dish rack for quickly draining water. Background Art

[0002] Cuvettes are generally made of quartz, glass, and quartz (acid and alkali resistant). Many different specifications of cuvettes are used in hydrometallurgy, chemical production, and chemical analysis and testing. Common devices for placing cuvettes include boxed and brackets, but both can only hold cuvettes of one size, which is quite limited. Although there is a multifunctional cuvette rack on the market, the cuvette racks on the market are all placed with the opening facing upward, and the residual water inside the used cuvette cannot be discharged, causing the residual liquid inside to affect the secondary use and cause unstable analysis results.

[0003] The existing Chinese patent application CN206911393U discloses a cuvette drain rack, which uses an electric cylinder and a movable cylinder in a support rod mechanism to place cuvettes of various lengths and sizes. However, when the cuvette is turned upside down, its inner bottom wall will contact the surface of the silicone sleeve, causing some residual liquid to be difficult to flow out, which still affects the secondary use; at the same time, the sizes of cuvettes on the market include not only cuvettes with different longitudinal sizes, but also cuvettes of 10mm-50mm in a conventional horizontal shape. Therefore, the support mechanism of the patent is not convenient for supporting and fixing the cuvette in a horizontal state, which is not conducive to the complete discharge of water inside the cuvette in a horizontal state, affecting the analysis result when it is used again, and the structure is relatively complex and the cost price is relatively high.

[0032] Specifically, the diameters of the upper disc 1, the lower disc 2 and the base 3 are all equal, and the diameter value is 210 mm. At the same time, the upper disc 1, the lower disc 2 and the base 3 are all made of transparent organic glass, which has a smooth surface, is beautiful and durable, and has the effects of corrosion resistance, acid and alkali resistance.

[0033] In this embodiment, the rectangular placement opening 4 includes a first placement opening 41, a second placement opening 42, a third placement opening 43, a fourth placement opening 44 and a fifth placement opening 45, and the first placement opening 41, the second placement opening 42, the third placement opening 43, the fourth placement opening 44 and the fifth placement opening 45 are orderly distributed on the upper disk 1, and the rectangular through opening 5 includes a first through opening 51, a second through opening 52, a third through opening 53, a fourth through opening 54 and a fifth through opening 55, and the first through opening 51, the second through opening 52, the third through opening 53, the fourth through opening 54 and the fifth through opening 55 are orderly distributed on the lower disk 2, and the first placement opening 41, the second placement opening 42, the third placement opening 43, the fourth placement opening 44 and the fifth placement opening 45 correspond to the first through opening 51, the second through opening 52, the third through opening 53, the fourth through opening 54 and the fifth through opening 55 respectively.

[0034] Specifically, the first placement port 41 is used to place a 10 mm cuvette, with a size of 14 mm × 14 mm, the second placement port 42 is used to place a 20 mm cuvette, with a size of 14 mm × 24 mm, the fourth placement port 44 is used to place a 30 mm cuvette, with a size of 14 mm × 34 mm, the fifth placement port 45 is used to place a 40 mm cuvette, with a size of 14 mm × 44 mm, and the third placement port 43 is used to place a 50 mm cuvette, with a size of 14 mm ×54mm; the first opening 51 has a size of 0.9×0.9mm, the second opening 52 has a size of 0.9×19mm, the fourth opening 54 has a size of 0.9×29mm, the fifth opening 55 has a size of 0.9×39mm, and the third opening 53 has a size of 0.9×49mm. The design function is that the lower disc 2 can receive the cuvette with the top of the upper disc 1 facing downward, ensuring that the cuvette of 10mm-50mm can be placed and the outflow of water inside it can be ensured.

[0035] In this embodiment, a thread groove 11 is provided at the top of the bracket 9, and a limiting groove 12 is provided at the bottom of the bracket 9. One end of the second fastener 10 is threadedly connected in the thread groove 11. A limiting protrusion 13 is connected at the center of the water collecting tank 8, and the bracket 9 is adapted to the limiting protrusion 13 through the limiting groove 12.

[0036] Specifically, by connecting the second fastener 10 with the bracket 9, the upper disc 1 and the lower disc 2 can be ensured to be stable, which is conducive to the placement of cuvettes of different sizes. By the matching design of the limiting protrusion 13 and the limiting groove 12, the bracket 9 can drive the upper disc 1 and the lower disc 2 to rotate, making it easy to take any cuvette.

[0037] In this embodiment, a plurality of arc-shaped supports 14 are fixedly connected to the bottom of the base 3 . The plurality of arc-shaped supports 14 are evenly distributed along the circumferential direction of the base 3 . Specifically, the arc-shaped supports 14 are used to support the base 3 to ensure stability.

[0038] In this embodiment, a first positioning hole 15 is respectively opened through the center of the upper disk 1 and the lower disk 2, and the second fastener 10 is arranged in the first positioning hole 15. Four second positioning holes 16 are respectively opened through the surface of the upper disk 1 and the lower disk 2, and the first fastener 7 is arranged in the second positioning hole 16.

[0039] Specifically, by designing the first fastener 7 in conjunction with the support body 6, a gap can be created between the upper disk 1 and the lower disk 2, thereby ensuring stability after the upper disk 1 and the lower disk 2 are connected while ensuring stability when the cuvette is placed. The first positioning hole 15 is used to connect the bracket 9 to ensure that the upper disk 1 and the lower disk 2 are located above the base 3, so that water flowing out of the cuvette when it is turned upside down drips into the sump 8 for collection, thereby reducing the problem of contaminating the desktop.

[0040] The working principle and use process of the utility model are as follows: when in use, the upper disc 1, the lower disc 2 and the bracket 9 are quickly installed manually, so that the bracket 9 can be placed on the limiting protrusion 13 for stable rotation after being connected to the second fastener 10. When the operator places the cleaned cuvettes of different sizes in the rectangular placement openings 4 of different sizes, the design of the lower disc 2 can be used to receive the cuvettes turned upside down, so that the cuvettes of 10mm-50mm can be placed, and the water inside can be dripped into the water collection tank 8 through the rectangular opening 5, so as to avoid the problem of dripping on the desktop and causing pollution. When the water needs to be processed, the bracket 9 can be separated from the base 3 by picking up the upper disc 1 and the lower disc 2, which is conducive to manual and rapid water processing, which is convenient and quick.
