Embodiment Construction
[0014] From figure 1 It can be seen from the figure that a medical detection photometer includes a light blocking device, a liquid replacement device, a cuvette replacement device, a photomultiplier tube 1, a cabinet 10, a shutter 3, and the like. Wherein the box body 10 is provided with a front end cover 29 , a rear end cover 19 , and an upper end cover 2 . The photomultiplier tube 1 and the box body 10 are jointly fixed above the base 17 and connected by screws to determine the relative positions of the two. Wherein, the photosensitive lens of the photomultiplier tube 1 protrudes from the left hole of the box body 10 .
[0015] From figure 1 , figure 2 It can be seen that the light blocking device includes a DC motor 22, a motor flange 25, a shaft coupling 23, a rotating shaft 14, a rotating shaft flange 24, a turntable, and a turntable flange. Turntable, turntable flange all have front and rear two, are respectively front turntable 28, back turntable 21, front turntabl...

The invention discloses a medical detection photometer, which includes a light blocking device, a liquid changing device, a cuvette changing device, a box body, and a shutter. The light blocking device includes a DC motor, a rotating shaft, a turntable, and a turntable flange. The turntable flanges are fixedly installed on the inside of the front end cover and the rear end cover of the box respectively, and the turntables are respectively installed between the turntable flange and the front end cover and between the turntable flange and the rear end cover; the turntable, turntable flange There are square holes on the front end cover and the rear end cover, and the square holes on the front end cover and the rear end cover are aligned with the square holes on the turntable flange; the rotating shaft runs through the box, the turntable is fixed on the rotating shaft, and the DC motor Connect the rotating shaft through the coupling and drive the turntable to rotate, and realize the opening and closing of the upper hole of the box through the alignment and misalignment of the upper hole of the turntable with the square hole on the turntable flange and the end cover. The invention has reasonable structure, convenient and reliable operation and use, does not need sealing material to seal and block light, and solves the problem of light leakage caused by sealing material wear.
Description
technical field [0001] The invention relates to an optical detection device, in particular to a medical detection photometer. Background technique [0002] As we all know, photometers are widely used in medicine and other fields. When the existing photometer forms a dark room inside the box, a sealing material is required for sealing. The sealing material is easy to wear when used for a long time. If it is not found in time, it will cause light leakage and affect the detection results. Moreover, after the sealing material is worn out, it is inconvenient to replace it. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a medical detection photometer with simple and reasonable structure, convenient and reliable operation, and no need for sealing material to seal and block light. [0004] In order to solve the above technical problems, the technical solution adop...
