Technical Field

[0001] This utility model relates to the field of spectrophotometer technology, and in particular to an ultraviolet-visible spectrophotometer. Background Technology

[0002] A spectrophotometer is a scientific instrument that breaks down complex light into spectral lines. Spectrophotometry uses the absorbance of light at specific wavelengths or within a certain wavelength range to perform qualitative or quantitative analysis of a substance. Different light sources have their own unique emission spectra, therefore different light-emitting bodies can be used as the instrument's light source.

[0003] The ultraviolet spectrophotometer has a built-in cuvette slot. The cuvettes are inserted into the cuvette slot. In order to keep the cuvettes stable, they are inserted tightly, resulting in greater friction and making the insertion of the cuvettes not very smooth.

[0004] In view of this, we propose a UV-Vis spectrophotometer. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: A UV-Vis spectrophotometer, see [link to example]. Figures 1 to 4 The spectrophotometer includes a housing 1, a touch screen body 2, a power connector 3, a data connector 4, a sample chamber 5, a flip cover 6, a cuvette slot 7, and cuvettes 9. The touch screen body 2, power connector 3, and data connector 4 are respectively embedded in the spectrophotometer housing 1. The sample chamber 5 is opened inside the spectrophotometer housing 1. The flip cover 6 is rotatably located at the opening of the sample chamber 5 corresponding to the opening of the spectrophotometer housing 1. The flip cover 6 is in a closed fit with the opening of the sample chamber 5. The cuvette slot 7 is arranged at the bottom of the sample chamber 5. Several cuvettes 9 are respectively connected to the cuvette slot 7 through several connecting structures 8.

[0037] The connecting structure 8 includes a U-shaped plate 802 and abutment springs 803; the U-shaped plate 802 is arranged in the cuvette groove 7; the two abutment springs 803 are respectively arranged on both sides of the bottom of the inner cavity of the U-shaped plate 802; wherein, the cuvette 9 is inserted into the inner cavity of the U-shaped plate 802, and there is a gap between the two sides of the inner cavity of the U-shaped plate 802 and the two sides of the cuvette 9, and the bottom sides of the cuvette 9 respectively abut against the two abutment springs 803.

[0038] This utility model, by setting a U-shaped plate 802 and an abutment spring 803, has the advantages of allowing the cuvette 9 to be inserted into the U-shaped plate 802, with sufficient space inside the U-shaped plate 802, and the cuvette 9 being positioned by the abutment spring 803, making it easy to insert and position the cuvette 9. This solves the problems of the cuvette 9 being too tight, having high friction, and not being able to insert the cuvette 9 smoothly.

[0039] Specifically, the top of the U-shaped plate 802 is higher than the top of the cuvette groove 7, and the top of the cuvette 9 is higher than the top of the U-shaped plate 802, making it convenient to insert and remove the cuvette 9.

[0040] Furthermore, the abutment spring 803 is arc-shaped, and the arched end of the abutment spring 803 abuts and engages with the cuvette 9; the arc-shaped abutment spring 803 abuts against the cuvette 9 without having too much contact area with the cuvette 9, so the cuvette 9 can be inserted smoothly.

[0041] It is worth noting that the connecting structure 8 also includes a fixing plate 801 and an insert 804;

[0042] The fixing plate 801 is fixed on the cuvette groove 7; the insert 804 is fixed on the outside of the U-shaped plate 802; wherein the insert 804 is inserted into the slot 8011 opened on one side of the fixing plate 801; wherein the insert 804 has a T-shaped cross section and is adapted to the slot 8011.

[0043] This utility model, by setting a fixing plate 801, a slot 8011, and an insert 804, has the advantages of installing the U-shaped plate 802 by mating the slot 8011 and the insert 804, and being easy to replace after the contact spring 803 loses its elasticity.

[0044] Working principle: Using the device of this invention, the U-shaped plate 802 is installed on the cuvette slot 7, and the insert 804 is inserted into the corresponding slot 8011. Reagent is placed in the cuvette 9, and the cuvette 9 is inserted into the U-shaped plate 802. After insertion, the curved abutment spring 803 is pressed, and the curved abutment spring 803 abuts against the cuvette 9, positioning it. The flip cover 6 is closed, and detection is performed using a spectrophotometer. After the detection is completed, the flip cover 6 is opened, and the cuvette 9 is removed.
