Description

Technical Field

[0001] The utility model belongs to the field of experimental equipment, in particular to a colorimetric dish auxiliary bracket for a photometer. Background Art

[0002] A photometer is a commonly used spectral analysis instrument. When using it, the experimenter injects the sample to be tested into a cuvette and places the cuvette into the optical path of the photometer. This allows the sample to be measured for its absorbance at a specific wavelength or wavelength range, facilitating qualitative and quantitative analysis of the sample.

[0003] Common cuvettes are usually equipped with two oppositely arranged frosted glass side walls and two oppositely arranged optical side walls. During operation, the experimenter should pick up the cuvette by the frosted glass side walls and avoid touching the optical side walls to ensure that the test results have good accuracy. However, during the process of injecting the sample, due to the small overall volume of the cuvette and the lack of a good protective structure on the outside of the optical side walls, the optical side walls are easily contaminated. Once the optical side walls are contaminated, it is very difficult for the experimenter to wipe and clean them, which not only affects the detection efficiency of the sample, but also affects the sample's light absorption, resulting in errors in the test results.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] A colorimetric cuvette auxiliary support for a photometer, the structure of which can be Figures 1-6 In this embodiment, the cuvette auxiliary holder for a photometer comprises a base plate 1, a cleaning rack, and multiple supporting seats 4. The cleaning rack is mounted on the top surface of the base plate 1, and the supporting seats 4 are movably mounted on the base plate 1. During use, the supporting seats 4 protect the cuvette 5 and move the cuvette 5 on the base plate 1. The cleaning rack is used to wipe the cuvette 5 after it has been removed from the supporting seats 4, thereby ensuring the cleanliness of the optical sidewalls of the cuvette 5.

[0032] Specifically, such as Figure 4 As shown, the cleaning rack includes two parallel mounting plates 2, each of which is perpendicular to the base plate 1, forming a cleaning channel between the two mounting plates 2, and each mounting plate 2 is provided with an avoidance cutout 21 connected to the cleaning channel. A guide groove 11 is provided on the top surface of the base plate 1, with the two ends of the guide groove 11 located on both sides of the cleaning rack, and the guide groove 11 passes through the cleaning rack along the avoidance cutout 21. Figure 3 and Figure 5 As shown, a guide column 41 is provided at the bottom of the supporting seat 4, a supporting groove 42 with a depth greater than the height of the cuvette 5 is provided on the top surface of the supporting seat 4, and a removal cutout 43 connected to the supporting groove 42 is provided on the front side wall and the rear side wall of the supporting seat 4.

[0033] In addition, to achieve a wiping cleaning effect of the cleaning rack on the contrast cuvette 5, a mounting groove 22 should be provided on the side wall of the mounting plate 2 near the cleaning channel. A detachable cleaning sheet 3 is provided inside the mounting groove 22, and a cleaning pad 31 is provided on the side wall of the cleaning sheet 3 near the cleaning channel. It should be noted that the cleaning pad 31 in this embodiment can be made of lens cleaning paper or other cleaning materials in the prior art (such as clean non-woven fabric).

[0034] When using this device, the user can first load the cuvette 5 to be injected with the sample into the interior of the supporting tank 42, and ensure that the two optical side walls of the cuvette 5 are respectively in contact with the left and right side walls of the supporting tank 42, and the two frosted glass side walls of the cuvette 5 are respectively in contact with the front and rear side walls of the supporting tank 42. Since the depth of the supporting tank 42 is greater than the height of the cuvette 5, the left and right side walls of the supporting seat 4 will block the optical side walls of the cuvette 5 to prevent the optical side walls from being contaminated during the sample injection process. At the same time, since the front and rear side walls of the supporting seat 4 are provided with removal cutouts 43, the user can contact the frosted glass side walls of the cuvette 5 through the removal cutouts 43, making it convenient to load or remove the cuvette 5 into or out of the supporting tank 42.

[0035] After assembling the cuvette 5 and the support 4, the user can slide the guide post 41 into the guide groove 42 and inject the sample into the cuvette 5. Because the guide groove 11 passes through the cleaning frame along the avoidance cutout 21, after the sample is injected, the user can drive the support 4 to slide along the guide groove 42 to enter the cleaning channel. Next, the cuvette 5 can be pulled upward to separate from the support 4 within the cleaning channel.

[0036] When the cuvette 5 is separated from the carrying tank 42, the cleaning pad 31 on the cleaning sheet 3 will contact the optical side wall of the cuvette 5, thereby wiping the optical side wall, improving the cleanliness of the optical side wall, and thus making the sample inspection result more accurate.

[0037] As an optional implementation of this embodiment, to facilitate the synchronous movement of multiple support bases 4 on the bottom plate 1, magnetic sheets 45 can be provided on both the left and right walls of the support bases 4. When a user loads multiple support bases 4 into the device, adjacent support bases 4 will be attracted to each other via the magnetic sheets 45, allowing the user to move multiple support bases 4 at once, thereby improving the convenience of use of the device.

[0038] To prevent the support base 4 from detaching from the base plate 1 when the cuvette 5 is pulled upward, a stopper 46 can be provided at the bottom of the guide post 41 in this embodiment. Accordingly, a stopper cavity 12 for accommodating the stopper 46 should be provided within the base plate 1, and the stopper cavity 12 should be connected to the guide groove 11. When the user pulls the cuvette 5 upward, the top surface of the stopper 46 will abut against the top inner wall of the stopper cavity 12, thereby preventing the support base 4 from ascending with the cuvette 5 and simplifying the separation of the cuvette 5 from the support groove 42.

[0039] Optionally, in order to facilitate the guide post 41 with the limiting piece 46 to enter the guide groove 11, a loading cutout 131 and a disengagement cutout 132 may be provided on the side wall of the bottom plate 1. Figure 4As shown, the loading cutout 131 and the disengaging cutout 132 are both connected to the limiting cavity 12, and the loading cutout 131 and the disengaging cutout 132 are respectively located on both sides of the cleaning rack. When in use, the user can load the limiting piece 46 into the limiting cavity 12 along the loading cutout 131 so that the guide post 41 enters the guide groove 11, and then start the sample injection work. After the cuvette 5 containing the sample is separated from the supporting seat 4, the user can move the limiting piece 46 out of the limiting cavity 12 along the disengaging cutout 132 to facilitate the loading of a new cuvette 5 into the supporting seat 4. Compared with the common cuvette holder, the present device can guide the user to manage multiple supporting seats 4 according to the sample injection situation in the cuvette 5 in the above manner, and load and disengage each supporting seat 4 in an orderly manner.

[0040] To prevent the cleaning sheet 3 from separating from the mounting slot 22 during use, a limiting strip is provided inside the mounting slot 22 in this embodiment, and a limiting slot 32 is provided on the cleaning sheet 3. When assembling the cleaning sheet 3 and the mounting slot 22, the user can insert the limiting strip into the limiting slot 32, thereby improving the installation reliability of the cleaning sheet 3 in the mounting slot 22 through the cooperation of the limiting strip and the limiting slot 32.

[0041] Furthermore, to prevent the cleaning sheet 3 from moving abnormally when wiping the optical sidewalls of the cuvette and to ensure a good wiping effect, a locking screw hole 23 communicating with the mounting slot 22 is provided on the sidewall of the mounting plate 2 away from the cleaning channel, and a locking bolt 231 is provided within the locking screw hole 23. After the cleaning sheet 3 is installed in the mounting slot 22, the user can screw the locking bolt 231 into the mounting slot 22 so that the end of the locking bolt 231 abuts against the cleaning sheet 3, thereby securing the position of the cleaning sheet 3 through the abutting effect.

[0042] As another optional implementation of this embodiment, to facilitate the user in determining the sample content in the cuvette 5 during sample injection, observation cutouts 44 communicating with the removal cutout 43 may be provided on both the front and rear sidewalls of the support base 4. The observation cutouts 44 should be located above the removal cutout 43 and be wider than the removal cutout 43. The provision of the observation cutouts 44 reduces the difficulty for the user in observing the cuvette 5, thereby facilitating the user's accurate determination of the sample injection volume in the cuvette 5 and preventing overflow of the sample in the cuvette 5 due to overinjection.

[0043] The following describes the effects of the above scheme:

[0044] This embodiment provides a cuvette auxiliary bracket for a photometer, which can protect the cuvette through the support seat to prevent the optical side wall of the cuvette from being contaminated when the sample is injected. At the same time, it can facilitate the user to contact the frosted glass side wall of the cuvette by removing the incision, thereby reducing the difficulty of disassembling and assembling the cuvette. Secondly, this device can wipe the optical side wall of the cuvette through the cleaning rack to improve the cleanliness of the optical side wall. In addition, this device can prevent the support seat and the cuvette from rising synchronously through the cooperation of the limiting cavity and the limiting plate, and can limit the cleaning plate through the limiting groove, the limiting strip and the locking bolt to prevent the cleaning plate from separating from the mounting groove.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
