Description

Technical Field

[0001] This utility model relates to the field of acid pH value detection, and in particular to a test tube colorimetric structure. Background Technology

[0002] In chemical reagent preparation or food production processes, it is necessary to test the approximate pH value of liquids. A common method is to place one or more test tubes containing the liquid to be tested on a test tube rack and place a colorimetric card to one side of the test tubes for color comparison. However, when the colorimetric card is too close to the test tubes, the reflected light can cause deviations in the actual color of the test tubes, leading to inaccurate colorimetric comparisons and significant errors in experimental results. Furthermore, while some test tube racks can fix the colorimetric card in place, eliminating the need for manual handling, the fixed position of the test tubes means that the distance between the test tubes and different color areas on the colorimetric card varies during color comparisons. Since the colorimetric card has many color areas, visual comparison can be tiring and prone to errors, hindering the efficiency of comparative experiments. Utility Model Content

[0003] The purpose of this invention is to provide a test tube colorimetric structure that is less prone to color deviation when comparing test tubes and colorimetric cards, and has a higher colorimetric accuracy.

[0004] To achieve the above objectives, this utility model provides a test tube colorimetric structure, including a base, a baffle on the top of the base, and a test tube area and a colorimetric card area separated by the baffle on the base; the base is provided with a test tube moving structure located in the test tube area, and a colorimetric card limiting part located in the colorimetric card area; a first light source is provided in the test tube area to illuminate the test tube, and a second light source is provided in the colorimetric card area to illuminate the colorimetric card.

[0005] As a further improvement of this utility model, the test tube moving structure is a test tube support, which is rotatably connected to the base via a rotating shaft.

[0006] As a further improvement of this utility model, the test tube holder includes an upper turntable, a column and a lower turntable connected in sequence from top to bottom, and the rotating shaft is connected to the middle of the lower turntable; the upper turntable is provided with a plurality of test tube limiting holes arranged around its rotation axis, and the top surface of the lower turntable is provided with a plurality of test tube limiting grooves arranged around its rotation axis, and the test tube limiting holes and test tube limiting grooves correspond one-to-one.

[0007] As a further improvement of this utility model, the colorimeter card limiting part includes two symmetrically arranged and parallel limiting strips, which together with the top surface of the base form a colorimeter card sliding groove.

[0008] As a further improvement of this utility model, a mark is provided on the top surface of the base on one side of the colorimetric card slide.

[0009] As a further improvement of this utility model, a reflector that can swing relative to the baffle is provided above the baffle. The reflector is located directly above both the test tube area and the colorimetric card area. The first light source and the second light source are both located below the reflector (8).

[0010] As a further improvement of this utility model, the reflector is rotatably connected to the baffle via a second rotating shaft.

[0011] Beneficial effects

[0012] Compared with the prior art, the advantages of the test tube colorimetric structure of this utility model are:

[0013] 1. When comparing the color of a liquid in a test tube with the colorimetric card, the corresponding test tube is moved to the side adjacent to the baffle using the test tube moving mechanism. Since the first light source illuminates only the test tube and the second light source illuminates only the colorimetric card, the baffle's light-blocking effect ensures that the light reflected from the colorimetric card has minimal impact on the test tube, preventing color deviation of the liquid inside the test tube. This allows for more accurate observation of the liquid's color against the colorimetric card. Furthermore, only the test tubes requiring comparison are moved to the baffle side, reducing the likelihood of misreading the test tube during colorimetric analysis.

[0014] 2. The test tube holder is rotatably connected to the base, which can prevent multiple test tubes from being inserted while avoiding the test tube holder from becoming too long.

[0015] 3. The colorimetric strip can slide along the groove of the colorimetric card, allowing the color area to be compared on the colorimetric card to be as close as possible to the test tube, making it easier for personnel to observe. Positioning the color area to be compared on the marked side makes it easier for personnel to locate the color area, reducing the likelihood of misreading the color area during comparison.

[0016] 4. With the reflector installed, there is no need for personnel to look down at the colorimetric card and test tubes. Personnel can see the liquid in the test tube and the color of the colorimetric card clearly by using the reflector from the front of the colorimetric structure, which reduces the difficulty of observation and is more ergonomic.

[0022] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] Example

[0024] The specific embodiments of this utility model are as follows: Figures 1 to 3 As shown, a test tube colorimetric structure includes a base 1, with a vertically arranged baffle 13 on the top of the base 1. The base 1 also has a test tube area 11 and a colorimetric card area 12 separated by the baffle 13. The base 1 has a test tube moving structure located in the test tube area 11 and a colorimetric card limiting part located in the colorimetric card area 12. A first light source 51 illuminating the test tube 4 is provided in the test tube area 11, and a second light source 52 illuminating the colorimetric card 6 is provided in the colorimetric card area 12. The color temperatures of the first light source 51 and the second light source 52 need to be the same, and they can respectively illuminate the test tube 4 located in the colorimetric card area 12 and the colorimetric card 6 located in the colorimetric card area 12.

[0025] The test tube moving structure is a test tube support 3, which is rotatably connected to the base 1 via a rotating shaft 2. The rotating shaft 2 is arranged vertically.

[0026] In this embodiment, the test tube holder 3 includes an upper turntable 31, a column 33, and a lower turntable 32 connected sequentially from top to bottom. The rotating shaft 2 is connected to the middle of the lower turntable 32. Both the upper and lower turntables 31 and 32 are circular. The upper turntable 31 has multiple test tube limiting holes 34 arranged around its axis of rotation, and the top surface of the lower turntable 32 has multiple test tube limiting grooves 35 arranged around its axis of rotation. The test tube limiting holes 34 and grooves 35 correspond one-to-one. In this embodiment, the test tube holder 3 has six sets of test tube limiting holes 34 and grooves 35, allowing for the simultaneous placement of up to six test tubes 4. The test tubes 4 pass through the test tube limiting holes 34, with their bottoms positioned within the grooves 35.

[0027] The colorimeter card limiting part includes two symmetrically arranged and parallel limiting strips 7, which together with the top surface of the base 1 form a colorimeter card slide groove. The length directions of the colorimeter card slide groove and the baffle 13 are parallel to each other.

[0028] The top surface of the base 1 on one side of the colorimetric card slide is marked with a mark 9. The mark 9 can be a raised dot or a different color from the base 1 for distinction.

[0029] A reflector 8, which can swing relative to the baffle 13, is provided above the baffle 13. The reflector 8 is located directly above both the test tube area 11 and the colorimetric card area 12. The first light source 51 and the second light source 52 are both located below the reflector 8, and both the first light source 51 and the second light source 52 illuminate obliquely downwards to avoid direct sunlight on the reflector 8. The first light source 51 and the second light source 52 can be LED lights.

[0030] The reflector 8 is rotatably connected to the baffle 13 via the second rotating shaft 81. A bolt can be installed at one end of the second rotating shaft 81. By tightening the bolt, the friction is increased, and the reflector 8 is prevented from loosening.

[0031] During colorimetric analysis, several test tubes 4 filled with liquid are placed on the test tube holder 3, and a colorimetric card 6 is placed on the colorimetric card slot. The first light source 51 and the second light source 52 are turned on. By rotating the test tube holder 3, the test tubes 4 to be compared are rotated to the side of the baffle 13. By sliding the colorimetric card 6 relative to the colorimetric card slot, a certain color area is moved to the side of the mark 9. Then, the personnel compare the color of the liquid in the test tube 4 with the color area of ​​the colorimetric card based on the image reflected by the reflector 8. Since the first light source 51 only illuminates the test tube 4 and the second light source 52 only illuminates the colorimetric card 6, and with the light-blocking effect of the baffle 13, the light reflected from the colorimetric card 6 will not significantly affect the test tube 4, avoiding color deviation of the actual color of the liquid in the test tube 4. This allows for more accurate observation of the color of the liquid in the test tube 4 and the colorimetric card 6.

[0032] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
