[0017] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0018] A typical embodiment of the utility model provides a portable spectrophotometer device, comprising a box body 1, and a box cover 2 is arranged on the top of the box body 1. A battery compartment 3 is arranged at the bottom of the inner side of the box body 1, a movable seat 5 for placing a spectrophotometer 4 is arranged on the top of the battery compartment 3, and a sponge pad 6 for pressing the spectrophotometer 4 is arranged at the bottom of the inner side of the box cover 2; a cuvette holder placement plate 7 is rotatably connected to the outer side wall of the box body 1.

[0019] According to the above embodiment, when the spectrophotometer 4 needs to be moved (for example, sampling and testing is required on site), the spectrophotometer 4 is placed in the box 1 for transfer. The box 1 is made of wood or plastic, which can protect the instrument. After arriving at the testing site, the spectrophotometer 4 can be taken out of the box 1 and the sample can be tested outside the box 1.

[0020] The movable seat 3 can also be separated from the box body 1. The movable seat 3 is taken out from the box body 1 and placed on the support surface. A leveling bolt can be set at the bottom of the movable seat 3. The leveling bolt is used to adjust the horizontality of the movable seat 3, and then the spectrophotometer 4 is placed on the movable seat 3 for detection.

[0021] Of course, the movable seat 3 and the spectrophotometer 4 may not be removed, and the detection may be performed directly in the box 1 . A certain operating space must be left between the movable seat 3 and the inner wall of the box 1 .

[0022] The cuvette holder placement plate 7 is rotated to a horizontal position, and the cuvette holder is placed on the cuvette holder placement plate. Batteries are placed in the battery compartment 3 to power the instrument.

[0023] In a relatively specific embodiment, a groove for accommodating the cuvette holder placing plate 7 is opened on one side wall of the outer side of the box body 1, an axis is arranged on the side of the groove, an axis hole is opened on the side of one end of the cuvette holder placing plate 7, and the cuvette holder placing plate 7 is rotatably connected to the box body 1 through the axis and the axis hole.

[0024] In order to keep the cuvette holder placement plate 7 rotated to the horizontal position stable, in a preferred embodiment, the bottom of the cuvette holder placement plate 7 is rotatably connected with a diagonal support plate 8, and a limiting groove 9 for limiting the rotation of the diagonal support plate 8 is provided on the side of the groove, and one end of the diagonal support plate 8 is connected to the bottom of the cuvette holder placement plate 7 through a rotating shaft. After the cuvette holder placement plate 7 is rotated to the horizontal position, the other end of the diagonal support plate 8 is inserted into the limiting groove 9, which is a long groove arranged obliquely. After the diagonal support plate 8 is inserted into the limiting groove 9, the diagonal support plate 8 can no longer continue to rotate downward.

[0025] In another preferred embodiment, grooves for accommodating the diagonal support plate 8 are provided at the bottom of both sides of the cuvette rack placement plate 7. After the detection is completed, the cuvette rack placement plate 7 is slightly rotated upward to disengage the diagonal support plate 8 from the limiting groove 9, and the cuvette rack placement plate 7 is rotated downward to return the diagonal support plate 8 and the cuvette rack placement plate 7 to their respective grooves for storage.

[0026] In a preferred embodiment, a fixed seat 10 is provided on the surface of the movable seat 3, and a limit groove suitable for the shape of the spectrophotometer is opened on the upper surface of the fixed seat 10. The spectrophotometer is placed in the limit groove to prevent the spectrophotometer from remaining relatively stable and colliding with the inner wall of the box. In order to further protect the spectrophotometer, the upper surface of the fixed seat is covered with a felt cloth protective layer.

[0027] The scope of protection claimed by the present invention is not limited to the above specific implementation methods. For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.
