Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
An exemplary embodiment of the present invention provides an ultraviolet-visible spectrophotometer, as shown in fig. 1-3, comprising a cuvette 1 and a sample box 2, wherein the sample box 1 is provided with a plurality of sample grooves 2. Positioning columns 4 are arranged on the frosted glass surfaces on the two sides of the cuvette 1, the positioning columns 4 are long strips, and the positioning columns 4 are fixed in the middle of the top end of the frosted glass of the cuvette 1 along the length direction of the cuvette 1; the sample cell 3 is provided with positioning shafts 5 symmetrically on the top surfaces of both sides, the positioning shafts 5 are used for assembling a positioning disc 6, the front end of the positioning disc 6 is provided with a positioning groove 7 matched with the positioning column 4, the rear end far away from the positioning groove 7 is provided with a through hole, and the through hole is matched with the positioning shafts 5.
In the above embodiment, the positioning posts 4 are rotatable about the positioning shafts 5, and the positioning disks 6 are pre-sized and the positioning shafts 5 are positioned so that the cuvettes 1 can be gripped exactly when the two positioning disks 6 are rotated into contact with the cuvettes 1. In the preferred embodiment, the positioning plate 6 is of a circular or oval structure, and the through hole is arranged by deviating from the center of the positioning plate 6, so that the positioning plate can be gradually close to the cuvette to avoid scratching the cuvette.
During the use, pack into positioning disk 6 in the location axle 5 of sample groove 3 both sides, sample groove 3 is put into to cell 1 and when 4 bottoms of reference column are a little higher than 3 tops of sample groove, begin to rotate positioning disk 6, make constant head tank 7 be close to the ground glass face of cell 1 gradually, finally make the constant head tank 7 contact cell 1 of both sides and press from both sides tight cell 1. Then, finely adjust the position of the cuvette 1 and push the cuvette 1 downwards, so that the positioning column 4 is embedded into the positioning groove 7. The position of the cuvette is fixed through the positioning disc and the positioning column, and the displacement of the cuvette is prevented.
