Embodiment 1

[0032] Please combine figure 1 with figure 2 The cuvette constant temperature device includes a thermostatic cylinder 1 for receiving the cuvette 2 and a docking block 4 for detachably arranged on the closed end of the cuvette 2, and one end of the constant temperature cylinder 1 has a docking block 4 and a comparative The cylinder socket (not marked) where the color dish 2 is inserted, and the other end of the thermostatic cylinder 1 is a closed end (not marked). A locking mechanism for locking the docking block 4 is arranged in the thermostatic cylinder 1 . The docking block 4 inserted with the cuvette 2 can be locked and fixed in the thermostatic cylinder 1 through the locking mechanism.

[0033] One side of the docking block 4 has a cuvette slot (not marked), and the closed end of the cuvette 2 is engaged with the cuvette slot. In this embodiment, the shape and structure of the cuvette slot matches the shape of the cuvette 2 , and the cuvette slot and the cuvette 2 are...

Embodiment 2

[0042] Please combine Figure 3 to Figure 5 The difference between this embodiment 2 and embodiment 1 is that the moving block 9 of this embodiment 2 is slidably arranged in the thermostatic cylinder 1, and the spring 11 may not be provided between the two rods 7 .

[0043] An unlocking mechanism for unlocking the docking block 4 is also provided in the thermostatic cylinder 1 . The unlocking mechanism includes two fixed mounts 12 that are symmetrically arranged on the moving block 9 with respect to the pressing block 5, and the two fixed mounts 12 are provided with sleeves 13 perpendicular to the moving direction of the cuvette 2, and the two sleeves 13 are aligned with each other. Screw rods 14 are threaded through the separated ends, and the separated ends of the two screw rods 14 are rotationally connected with the ends of the two rod parts 7 away from the corresponding hook parts 8 respectively. By driving the sleeve 13 to rotate, it can interact with the screw 14, and u...

Abstract

The invention relates to the technical field of chemical research equipment, and discloses a cuvette constant temperature device which comprises a constant temperature cylinder used for containing a cuvette and a butt joint block detachably arranged at the closed end of the cuvette, and one end of the constant temperature cylinder is provided with a cylinder insertion opening allowing the butt joint block and the cuvette to be inserted. A locking mechanism for locking the butt joint block is arranged in the constant temperature cylinder. According to the cuvette constant temperature device, the butt joint block for fixing the closed end of the cuvette and the locking mechanism for locking and fixing the butt joint block in the constant temperature cylinder are additionally arranged in the constant temperature cylinder, so that the cuvette inserted in the constant temperature cylinder can be effectively fixed, and the situation that the cuvette accidentally falls off when the constant temperature cylinder moves is avoided; therefore, smooth measurement of a subsequent optical system is ensured.

Description

technical field [0001] The invention relates to the technical field of chemical research equipment, in particular to a cuvette constant temperature device. Background technique [0002] The cuvette is a container used to hold the color solution during measurement. During the measurement of the instrument, the temperature has a certain influence on the photoelectric element and the degree of fogging. When the ambient temperature changes greatly, the photoelectric element of the instrument changes. As a result, the measurement data is unstable, so it is very important to ensure the constant temperature of the cuvette device for the stability of the measurement results. [0003] At present, the thermostatic devices on the market mainly include structures such as thermostatic cylinders and temperature control components. Usually, the cuvette is directly inserted into the mouth of the thermostatic cylinder, and the temperature of the cuvette is controlled by a temperature contro...
