However, the diameters of existing test tubes for storing chemical drugs are different, and the structure of the spectrometer used to position the test tubes is relatively simple, which obviously makes it impossible for the spectrometer to position test tubes of various diameters, which has a major defect.

[0023] Example 1

[0024] See also Figure 1-5 The utility model provides a technical solution: a device for detecting multiple chemical drugs, including a spectrometer 1, a storage cavity 11 is provided on the front side of the inner cavity of the spectrometer 1, a carrier plate 13 is installed in the storage cavity 11, a movable plate 16 is fixedly installed on the upper end of the inner cavity of the storage cavity 11 through an electric push rod 15, a plurality of mounting sleeves 14 are provided on the lower end surface of the carrier plate 13, a plurality of detection probes 17 matching the positions of the mounting sleeves 14 are fixedly installed on the lower end surface of the movable plate 16, the upper ends of the detection probes 17 are electrically connected to the spectrometer 1 through wires, a rotating ring 35 is rotatably installed on the upper end surface of the mounting sleeve 14, and a plurality of mutually fitting positioning blocks 3 are slidably installed at equal intervals between the mounting sleeve 14 and the rotating ring 35.

[0025] Working principle: When installing the test tube, the test tubes with different diameters can be inserted into the installation sleeves 14 respectively, and then the rotating ring 35 is rotated at the upper end of the installation sleeve 14. Through the sliding cooperation between the positioning block 3, the installation sleeve 14 and the rotating ring 35, the rotating rotating ring 35 can drive each positioning block 3 to shrink inward to fit with the periphery of the test tube, so that the test tube can be positioned in the installation sleeve 14, and then the carrier plate 13 is installed in the storage chamber 11, and the door of the storage chamber 11 is closed to complete the installation of the test tube;

[0026] When testing the chemical drugs inside the test tube, the electric push rod 15 is started through the operation panel on the surface of the spectrometer 1 to drive the movable plate 16 to move downward, so that each detection probe 17 can be inserted into the test tube. In conjunction with the internal processor of the spectrometer 1, the type and proportion of the chemical drugs inside each test tube can be tested, and the test results can be displayed on the surface display of the spectrometer 1 or on an external computer.

[0027] Example 2

[0028] A concave cavity 31 is formed on the upper end surface of the carrier plate 13 and is interconnected with the upper end of the mounting sleeve 14. The positioning block 3 is arranged in the concave cavity 31. A plurality of mutually matching limiting grooves 32 and arc-shaped grooves 36 are formed on the upper end surface of the concave cavity 31 and the lower end surface of the rotating ring 35, respectively. The plurality of arc-shaped grooves 36 are inclinedly arranged. A sliding shaft 34 and a limiting slider 33 that are slidably matched with the arc-shaped grooves 36 and the limiting grooves 32 are fixedly mounted on the upper and lower end surfaces of the plurality of positioning blocks 3.

[0029] Through the sliding cooperation between the limiting slider 33 and the limiting slide groove 32, the movement direction of each positioning block 3 can be limited in the concave cavity 31, so that the rotating ring 35 can drive each positioning block 3 to shrink inward or expand outward through the sliding cooperation between the inclined arc slide groove 36 and the sliding shaft 34.

[0030] Example 3

[0031] A support plate 4 is provided inside the mounting sleeve 14, a limited sliding cavity 41 is provided on the periphery of the mounting sleeve 14, a movable block 42 which slides with the limited sliding cavity 41 is fixedly installed on the periphery of the support plate 4, a movable sleeve 43 is rotatably installed on the periphery of the mounting sleeve 14, a threaded curved groove 45 is provided on the inner wall of the movable sleeve 43, and a protrusion 44 which slides with the threaded curved groove 45 is fixedly installed on the outer end surface of the movable block 42.

[0032] Since the differences between the test tubes of different models are respectively reflected in the diameter and length, in order to ensure that the heights of the test tubes are consistent so that each detection probe 17 can be in full contact with the chemical drugs inside each test tube, it is necessary to adjust the height of each test tube in the installation sleeve 14;

[0033] During adjustment, the movable sleeve 43 can be restricted on the periphery of the mounting sleeve 14. The mounting sleeve 14 can restrict the movement direction of the support plate 4 through the sliding cooperation between the limiting sliding cavity 41 and the movable block 42, so that the rotating movable sleeve 43 can drive the support plate 4 to move up and down in the mounting sleeve 14 through the threaded cooperation between the protrusion 44 and the threaded curved groove 45. Since the lower end of the test tube is in contact with the support plate 4, the support plate 4 that moves up and down can adjust the height of the test tube in the support plate 4.

[0035] A mounting frame 2 is fixedly installed in the storage cavity 11, a positioning frame 22 matching the mounting frame 2 is fixedly installed on the periphery of the carrier plate 13, a plurality of limit plug holes 21 are opened on the upper end surface of the mounting frame 2, and a limit plug rod 23 plugged into the limit plug holes 21 is fixedly installed on the lower end surface of the positioning frame 22.
