Abstract

The invention provides a cuvette test fixing device, comprising: a support frame, a light source fixing block, a light source, a detector fixing block, a detector, a fixing cavity, a driving shaft, a driving shaft fixing block, an elastic component and a self-locking switch ;The drive shaft can switch between the first position and the second position under the action of external force; when the drive shaft is in the first position, press the drive shaft once, the drive shaft switches from the first position to the second position, and the drive shaft The lower end of the drive shaft is locked in the self-locking switch; when the drive shaft is in the second position, press the drive shaft once, the lower end of the drive shaft is unlocked by the self-locking switch, and returns to the first position under the action of the elastic member. The invention provides a cuvette test fixture, which can be put in and taken out quickly, which solves the problem that in the prior art, the cuvette test fixture is not equipped with the function of fast putting in and taking out at the same time, which is not conducive to flow operation and automatic testing Disadvantages of the process.

Description

technical field [0001] The invention relates to the field of testing machinery and precision mechanical mechanisms, in particular to a cuvette testing fixture. Background technique [0002] Cuboid cuvettes are often used in the testing of chemical reagents. Generally, the chemical reagents need to be put into the cuvette, and then the cuvette containing the chemical reagent to be tested is put into the test instrument. The instrument illuminates the cuvette at one end through the light source. The chemical reagent inside emits a spectrum, and the other end receives the spectrum through the detector for spectral analysis, so as to obtain the target index of the chemical reagent to be tested. When testing the chemical reagents in the cuvette, it is necessary to ensure that the liquid in the cuvette is sufficient. The cuvette containing the liquid to be tested can be quickly put into the test instrument and its position is stable, and it can be taken out quickly and convenientl...
