DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application solves the problem in the prior art that, although the pesticide residue detection device can realize rapid detection of a single group of samples, when multiple groups of samples need to be detected, the samples need to be loaded and detected separately, which makes the detection speed slow and is not convenient for realizing rapid detection of multiple groups of samples.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model embodiment discloses a pesticide residue SERS online rapid detection device that is convenient for rapid detection of multiple samples. Figure 1-4 As shown, it comprises a detection device body 1, on which a SERS detection sensor 2 is arranged, a carrying plate 3 is fixedly connected to the detection device body 1, and a detection plate 4 is movably connected inside the detection device body 1 and above the carrying plate 3;

[0025] A central axis 402 is provided at the bottom of the detection plate 4, and a limiting component for limiting the central axis 402 is provided at the bottom of the carrying plate 3;

[0026] A plurality of sample slots 401 are provided inside the detection disk 4 .

[0027] Furthermore, the limiting assembly includes a vertical plate 5 fixedly connected to the bottom of the supporting plate 3, a screw rod 6 is threadedly connected to the vertical plate 5, a positioning block 7 is rotatably connected to the screw rod 6, and the center axis 402 is movably clamped between the two groups of positioning blocks 7. The overall structure of the limiting assembly is simple. When the limiting assembly is used to limit the center axis 402, the screw rod 6 is directly rotated to push the positioning block 7 to move, so that the center axis 402 is clamped between the two groups of positioning blocks 7. The operation is convenient, time-saving and labor-saving, thereby facilitating the loading and replacement of the detection disk 4, and the detection disk 4 is also easy to clean.

[0028] Furthermore, a lateral support rod 701 is fixedly connected to the positioning block 7 , and the lateral support rod 701 penetrates the vertical plate 5 and extends outward. The lateral support rod 701 is provided to provide lateral support to the positioning block 7 , thereby ensuring that the positioning block 7 is subjected to stable force.

[0029] Furthermore, a plurality of groups of balls 702 are provided on the positioning block 7. The provided balls 702 facilitate the positioning block 7 to engage and limit the central shaft 402, and the central shaft 402 has little resistance when rotating.

[0030] Specifically, a rotating handle 601 is provided on the screw rod 6, and a hand wheel 403 is provided on the top of the detection disk 4. The rotating handle 601 makes the screw rod 6 easy and labor-saving to rotate, and the hand wheel 403 makes it easy to rotate the detection disk 4.

[0031] It is particularly disclosed that a slot 301 corresponding to the central axis 402 is opened on the carrier plate 3, and support legs 8 are provided at the bottom of the carrier plate 3 and the detection device body 1. The slot 301 is set to limit the central axis 402, and the support legs 8 are set to support the entire device.

[0032] The pesticide residue SERS online rapid detection device, which is convenient for rapid detection of multiple samples, is used by first placing multiple groups of samples that need to be detected for pesticide residues in the sample slots 401 of the detection disk 4 respectively, and then clamping the detection disk 4 on the detection device body 1 and the carrier plate 3, while clamping the central axis 402 in the clamping slot 301. After the clamping is complete, the clamping limit of the central axis 402 is achieved through the limit assembly, and then the hand wheel 403 is directly rotated to drive the detection disk 4 to rotate, so that the pesticide residues of different samples in the multiple groups of sample slots 401 can be quickly detected through the SERS detection sensor 2.

[0033] When using the limit assembly to limit the center axis 402, it is sufficient to directly rotate the handle 601, which is easy to operate. The rotating handle 601 drives the screw rod 6 to rotate, and the screw rod 6 pushes the positioning block 7 to move horizontally. The positioning block 7 drives the lateral support rod 701 to move along the vertical plate 5. Finally, the center axis 402 is clamped between the two groups of positioning blocks 7 for limiting. The design of the ball 702 is convenient to reduce the rotation resistance of the center axis 402, making it easy to rotate the detection disk 4.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
