DETAILED DESCRIPTION

[0019] like Figures 1-2 As shown, the utility model provides a spectrum auxiliary measurement device, including a horizontally arranged base 1; a vertical fixed rod 2 is provided on the base 1; a positioning shaft 3 is coaxially connected to the fixed rod 2; a horizontal rotating bar 4 is rotatably sleeved on the positioning shaft 3; a horizontal positioning bottom bar 5 is connected to one side of the rotating bar 4; an arc-shaped positioning bottom groove is opened on the top wall of the positioning bottom bar 5; a positioning rod 6 located on both sides of the positioning bottom groove is vertically connected to the positioning bottom bar 5, and a positioning top bar 7 is slidably sleeved on the positioning rod 6; an arc-shaped positioning top groove is opened on the side of the positioning top bar 7 close to the positioning bottom bar 5; a positioning nut 8 is threadedly connected to each positioning rod 6 and is located on the side of the positioning top bar 7 away from the positioning bottom bar 5.

[0020] The principle and beneficial effects of the above technical solution:

[0021] Place the spectrometer on the base 1, then extend the measuring probe between the positioning top bar 7 and the positioning bottom bar 5, and then turn the nut to move the positioning top bar 7 downward, so as to cooperate with the positioning bottom bar 5 to clamp and position the measuring probe, so that the measuring probe is clamped between the positioning top groove and the positioning bottom groove, and then by rotating the rotating bar 4, the orientation of the measuring probe can be adjusted, and the measurement direction can be adjusted.

[0022] In the present application, the positioning top bar 7 and the positioning bottom bar 5 cooperate with each other to adapt to measuring probes of different sizes, improve the adaptability and versatility of the device, and can firmly clamp measuring probes of different sizes; because the rotating bar 4 is rotatably sleeved on the positioning shaft 3, the orientation of the measuring probe after clamping can be adjusted by rotating the rotating bar 4, and the measuring direction can be easily adjusted, thereby improving the flexibility and controllability of the measurement and adapting to different measurement scenarios and needs.

[0023] In this embodiment, Figure 2 As shown, rubber pads 9 are provided in the positioning top groove and the positioning bottom groove.

[0024] The principle and beneficial effects of the above technical solution:

[0025] The rubber pad 9 provides a soft contact surface, which can relieve the pressure of the positioning top strip 7 and the positioning bottom strip 5 on the measuring probe, thereby effectively protecting the measuring probe from damage or scratches.

[0026] In this embodiment, Figure 2As shown, a horizontal rotating hole is penetrated through the rotating bar 4; a rotating rod 10 is coaxially rotatably connected in the rotating hole; one end of the rotating rod 10 extends out of the rotating hole and is connected to one end of the positioning bottom bar 5; the other end of the rotating rod 10 extends out of the rotating hole from the side away from the positioning bottom bar 5, and is connected to a pull ring 11; a tightening groove connected to the rotating hole is opened on the rotating bar 4; a tightening screw 12 capable of tightening the rotating rod 10 is threadedly connected in the tightening groove.

[0027] The principle and beneficial effects of the above technical solution:

[0028] By adjusting the angle of the rotating rod 10 through the pull ring 11, the angle of the clamped measuring probe can be flexibly adjusted to adapt to different measurement scenarios and needs, thereby improving the flexibility and applicability of the measurement; at the same time, after the angle is adjusted, the rotating rod 10 can be tightened by screwing the tightening screw 12 to prevent the rotating rod 10 from accidentally rotating and changing the angle of the measuring probe, thereby ensuring the accuracy and reliability of the measurement.

[0029] In this embodiment, Figure 1 As shown, a fixing tube 13 is vertically provided on the base 1; the fixing rod 2 is threadedly connected in the fixing tube 13; a fixing hole connected to the fixing tube 13 is opened on the circumferential side of the fixing tube 13; the fixing hole is arranged near the upper end of the fixing tube 13; a fixing screw 14 capable of tightening the fixing rod 2 is threadedly connected in the fixing hole.

[0030] The principle and beneficial effects of the above technical solution:

[0031] By rotating the fixing rod 2, the measuring height of the measuring probe can be adjusted to improve the flexibility of measurement; when the measuring probe reaches the predetermined measuring height, the fixing screw 14 is turned so that the fixing screw 14 is pressed against the fixing rod 2, which can ensure that the measuring probe will not move accidentally after reaching the predetermined measuring height, thereby ensuring the accuracy of the measurement.

[0032] In this embodiment, Figure 1 As shown, two support bars 15 are horizontally provided on the base 1 and are located on one side of the fixed rod 2, and the two support bars 15 are parallel to each other; an intermediate plate 16 with a top higher than the support bar 15 is vertically connected between the two support bars 15; a slide groove 17 is opened on the top wall of each support bar 15 and is arranged along the length direction; a slider is slidably arranged in each slide groove 17; a moving bar 18 connected to the two sliders is slidably arranged on the support bar 15, and the moving bar 18 is parallel to the intermediate plate 16; a driving motor 19 is connected to one of the support bars 15; the power end of the driving motor 19 rotates and extends into the slide groove 17, and is connected to a screw; the other end of the screw is rotatably connected to the side wall corresponding to the slide groove 17, and the screw is threadedly connected to the slider; a positioning rod 20 parallel to the screw is rotatably connected between the opposite side walls in the other slide groove 17, and the positioning rod 6 slides through the corresponding slider.

[0033] The principle and beneficial effects of the above technical solution:

[0034] The spectrometer is placed on the two support bars 15 and in contact with the middle plate 16. The screw is then driven by the drive motor 19 to rotate, thereby driving the slider to slide in the slide groove 17. Under the action of the positioning rod 6, the two sliders can slide synchronously, thereby driving the moving bar 18 to move toward the middle plate 16. The moving bar 18 and the middle plate 16 cooperate with each other to position and clamp the spectrometer.

[0035] By the cooperation between the movable bar 18 and the middle plate 16 , the spectrometer can be accurately positioned and clamped to ensure its stable and accurate position, which is beneficial to the stability and accuracy during the measurement process.
