[0034] Please refer to Figure 1-Figure 7 A portable Raman pesticide residue detection substrate base includes a base 1, an adjustment column 2, a cover plate 3 and a plurality of positioning beads 4.

[0035] like Figure 1-Figure 4 and Figure 6 As shown, the base 1 is used to connect the Raman instrument, and the adjustment column 2 is used to place the substrate; the base 1 is movably connected to the adjustment column 2 to facilitate changing the height of the base 1, thereby adjusting the gap between the Raman instrument and the substrate;

[0036] Specifically, the base 1 has a cavity, and a threaded hole 1b communicating with the cavity is provided at the bottom of the base 1. The adjusting column 2 has an external thread that matches the threaded hole 1b. By rotating the base 1 or the adjusting column 2, the gap between the Raman instrument and the substrate can be adjusted to ensure the collection of high-quality spectra; one end of the adjusting column 2 extends into the cavity through the threaded hole 1b, and a groove 2a is provided on the top of the adjusting column 2 to facilitate the placement of the substrate to meet the center positioning requirement; a detection hole 1a is provided on the top of the base 1, and the detection hole 1a is located directly above the groove 2a. When the Raman instrument is connected to the base 1, the substrate placed on the groove 2a is detected through the detection hole 1a.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, a card slot 1c is provided on the top of the base 1, and the Raman instrument has an accessory interface that matches the shape of the card slot 1c. When the Raman instrument is connected to the base 1, the accessory interface is snapped into the card slot 1c, and the base 1 and the Raman instrument are locked by friction.

[0038] In this embodiment, Figure 7 As shown, the inner bottom of the base 1 is provided with a scale to facilitate rapid adjustment of the optical path for batch detection.

[0039] like Figure 1 As shown, the positioning bead 4 includes a cylinder 41, a ball 42 and a spring 43. A plurality of positioning holes 1d are provided on the top of the base 1. The cylinder 41 is arranged in the positioning hole 1d, and the ball 42 is connected to the cylinder 41 through the spring 43. When the spring 43 is in a non-compressed state, the height of the top of the ball 42 exceeds the cylinder 41. This arrangement is because the bottom of the accessory interface of the Raman instrument has a positioning groove. When the accessory interface of the Raman instrument is inserted into the slot 1c, the spring 43 is compressed and the ball 42 is located in the cylinder 41. As the accessory interface of the Raman instrument continues to be inserted, when the positioning groove of the accessory interface of the Raman instrument is just located above the ball 42, the spring 43 rebounds and inserts the ball 42 into the positioning groove, completing the positioning of the Raman instrument, so that the detection component of the Raman instrument can just detect the substrate placed on the groove 2a through the detection hole 1a.

[0040] In this embodiment, the number of the positioning beads 4 is preferably two, because the number of the positioning grooves of the Raman instrument accessory interface is two, and by providing two positioning beads 4, the two round balls 42 are respectively inserted into two different positioning grooves.

[0041] It should be noted that the positioning groove of the Raman instrument accessory interface has an arc. When the Raman instrument needs to be taken out, the Raman instrument is pulled outward, and the ball 42 compresses the spring 43 downward, thereby completing the separation from the positioning groove without causing motion interference.

[0042] like Figure 1 and Figure 2 As shown, the base 1 is provided with a cover 3 that can be opened and closed. When the cover 3 is opened, it is convenient to place the substrate on the adjusting column 2 or take the substrate out from the adjusting column 2. When the cover 3 is closed and the Raman instrument is connected to the base 1, the cavity of the base 1 is in a sealed and dark environment, meeting the light shielding requirements during detection, so that the Raman instrument can detect the substrate.

[0043] Specifically, a circular opening 1e is provided on one side of the base 1, and a plurality of arc grooves 1f are provided on the circumferential inner wall of the opening 1e. The base 1 is also provided with a plurality of through grooves 1g connected with the arc grooves 1f; a plurality of protrusions 31 are provided in the circumferential direction of the cover plate 3, and the protrusions 31 enter the arc grooves 1f through the through grooves 1g, and the cover plate 3 is rotated. At this time, the protrusions 31 abut against the arc grooves 1f to fix the cover plate 3 at the opening 1e; accordingly, when the cover plate 3 needs to be removed, it is only necessary to rotate the cover plate 3 in the opposite direction and align the protrusions 31 with the through grooves 1g to remove the cover plate 3.

[0044] In this embodiment, Figure 1 As shown, when the cover plate 3 is fixed at the opening 1e, one end of the cover plate 3 extends outside the base 1 to facilitate the rotation of the cover plate 3, so as to remove the cover plate 3 from the opening 1e or install it at the opening 1e; the surface of the protruding part of the cover plate 3 also has knurling to increase the friction when in contact with the operator, thereby achieving an anti-slip effect.

[0045] The working principle of this embodiment is:

[0046] When in use, the Raman instrument is fixed on the base 1, the cover 3 is opened, the substrate is placed on the adjustment column 2, and then the cover 3 is closed; then the height of the base 1 is changed so that the gap between the Raman instrument and the substrate is in a suitable range, and the Raman instrument detects the substrate.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
