[0002] A multifunctional optical analyzer is a device with multi-channel detection function that can quickly measure absorbance and fluorescence intensity. It is mainly used as a research laboratory facility or as a general optical analysis instrument in the fields of medicine, pharmaceuticals, environment, food, etc.

[0003] With the continuous development of modern production technology, the requirements for detection accuracy are gradually increasing, and the requirements for detection accuracy and data reliability of detection equipment are also increasing. However, the multifunctional optical analyzers currently used have the following problems that restrict detection accuracy and reliability: First, the positioning of the light source and the sample to be tested is unstable during detection, and incident light offset often occurs during the measurement process, requiring multiple measurements to ensure the reliability of the measured values; second, during measurement, it is easily affected by external light and temperature changes, resulting in reduced measurement accuracy.

[0004] Therefore, in view of the deficiencies in the prior art, the utility model designs a test box structure applied to a multifunctional optical analyzer to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the utility model. Utility Model Content

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to provide a test box structure applied to a multifunctional optical analyzer, improve the positioning accuracy and stability between the light source and the sample to be tested, and reduce the influence of external light and temperature on the test results.

[0007] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is to disclose a test box structure applied to a multifunctional optical analyzer, including a test box body, a sample rack is provided on the test box body, and a box cover assembly is provided on the sample rack.

[0011] The preferred technical solution is: a light outlet is also provided on the covering structure, and the light outlet is arranged corresponding to the sample hole slot of the fluorescent sample area. The light outlet provides an emission channel for the incident light used to excite fluorescence, thereby preventing the incident light from reflecting in the fluorescent detection area and interfering with the detection result.

[0012] The preferred technical solution is: the covering structure is made of heat-insulating material to isolate the absorption light detector and the absorption light sample area from heat exchange with the outside world.

[0013] The preferred technical solution is: a wedge-shaped guide block is provided on the baffle plate to facilitate the sample rack to enter the positioning groove, thereby reducing the difficulty of positioning.

It should be noted that the above structure is only exemplary and not restrictive. In this embodiment, the baffles 11 are separated and fixed on the test box body 1, but in other embodiments, the baffles 11 can be connected together, or in other embodiments, the positions of the baffles and the test box body 1 are adjustable.

[0026] like Figure 1 and Figure 2 As shown, the baffle plate 11 is provided with a wedge-shaped guide block 11a for facilitating the sample rack 2 to enter the positioning groove 12. The wedge-shaped guide block 11a assists the installation and positioning of the sample rack 2. It should be noted that the wedge-shaped guide block 11a can be located on the baffle plates 11 on the front and rear sides, or can be set on the baffle plates 11 all around, and the number can also be one or more.

[0027] like Figure 1 and Figure 2 As shown, a guide groove 13 is provided at the bottom of the test box body 1, a positioning bayonet 13a is provided on the guide groove 13, and slide rails 14 are provided on both sides of the test box body 1. The guide positioning mechanism ensures that the test box body 1 is accurately positioned in the multifunctional optical analyzer, thereby ensuring the stability of the relative position between the test box body 1 and the light source.
