Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection technology, and in particular to a rapid detection device for pesticide residues in soybeans. Background Technology

[0002] The sample is mixed with a specific reaction solution in a reagent tube, and then the reagent tube is placed into the detection device for analysis. However, the existing soybean pesticide residue detection device has certain operational inconveniences in the sample pretreatment stage. In particular, after the soybean is mixed with the reaction solution, the operator has to hold the reagent tube and put it into the detection machine. Since the reagent tube itself lacks an effective fixing or support structure, it is easy to tilt, shake or even tip over during placement, which not only affects the detection efficiency, but may also lead to sample contamination or reagent spillage, affecting the accuracy and repeatability of the detection results. In addition, manually supporting the reagent tubes increases the labor intensity of operators and reduces the automation level and operational smoothness of the overall testing process. To address these issues, we propose a rapid detection device for soybean pesticide residues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid detection device for pesticide residues in soybeans.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rapid detection device for pesticide residues in soybeans includes a detection device body, a support base at the bottom of the detection device body, and a bottom frame at the bottom of the support base. A pull-out frame is inserted inside the bottom frame, and two sets of support rods are installed inside the pull-out frame. The two sets of support rods are symmetrically fixed to the inner wall of the pull-out frame. A support plate is installed at the top of the support rods, and a circular groove is evenly opened on the surface of the support plate. A fixing ring is fixedly installed inside the circular groove. A cover plate is fixedly installed on the front of the bottom frame.

[0005] Preferably, the fixing ring has symmetrical holes and slots on both sides, and a pin is inserted into the hole or slot. A fixing piece is fixedly connected to one end of the pin outside the fixing ring. A first spring is sleeved on the surface of the pin, and one end of the first spring is fixed to the outer wall of the fixing ring, while the other end of the first spring is fixed to the fixing piece.

[0006] Preferably, the pin is fixedly connected to a first guide block at one end inside the fixing ring, and the top of the first guide block is inclined from top to bottom.

[0007] Preferably, slide rails are symmetrically provided on both sides of the bottom frame, and limit blocks are symmetrically fixedly installed on both sides of the pull-out frame, with the limit blocks inserted inside the slide rails.

[0008] Preferably, the support base has symmetrical inner grooves on both sides, and an extension rod is inserted inside the inner groove. A crossbar is fixedly installed at the end of the extension rod away from the inner groove, and a limit plate is fixedly installed at the top of the crossbar.

[0009] Preferably, the extension rod is fixed to the inner wall of the inner groove by a second spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A rapid detection device for pesticide residues in soybeans includes a detection device body 1, a support base 2 at the bottom of the detection device body 1, and a bottom frame 3 at the bottom of the support base 2. A pull-out frame 8 is inserted inside the bottom frame 3, and two sets of support rods are installed inside the pull-out frame 8. The two sets of support rods are symmetrically fixed to the inner wall of the pull-out frame 8. A support plate 9 is installed at the top of the support rods, and a circular groove is evenly opened on the surface of the support plate 9. A fixing ring 10 is fixedly installed inside the circular groove. A cover plate 4 is fixedly installed on the front of the bottom frame 3.

[0016] Furthermore, refer to Figure 4 It can be seen that the fixing ring 10 has symmetrical holes and slots on the left and right sides, and a pin 11 is inserted into the inside of the holes and slots. The end of the pin 11 located outside the fixing ring 10 is fixedly connected to the fixing piece 12. The surface of the pin 11 is fitted with a first spring 13, and one end of the first spring 13 is fixed to the outer wall of the fixing ring 10, and the other end of the first spring 13 is fixed to the fixing piece 12. During use, the first spring 13 pushes the pin 11 to limit and support the reagent tube, preventing it from tipping over.

[0017] Furthermore, refer to Figure 4 It can be seen that the pin 11 is fixedly connected to the first guide block 14 at one end inside the fixing ring 10, and the top of the first guide block 14 is inclined from top to bottom. During use, the first guide block 14 can play a guiding role to facilitate the insertion of the reagent tube.

[0018] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the bottom frame 3 has symmetrical slide rails on both sides, and the pull-out frame 8 has symmetrical fixed limit blocks 5 on both sides. The limit blocks 5 are inserted into the slide rails. During use, the limit blocks 5 cooperate with the slide rails to prevent detachment.

[0019] Furthermore, refer to Figure 4 and Figure 5 It can be seen that the support base 2 has symmetrical inner grooves on both sides, and an extension rod 16 is inserted inside the inner groove. A crossbar 6 is fixedly installed at the end of the extension rod 16 away from the inner groove, and a limit plate 7 is fixedly installed at the top of the crossbar 6. During use, the limit plate 7 can limit the detection equipment body 1 and play a limiting role.

[0020] Furthermore, refer to Figure 5It can be seen that the extension rod 16 is fixed to the inner wall of the inner groove by the second spring 15. One end of the second spring 15 is fixed to the inner groove, and the other end of the second spring 15 is fixed to the extension rod 16. During use, the extension rod 16 can move along the inside of the inner groove to adapt to the limited use of the detection equipment body 1 of different sizes. The extension rod 16 can also be fixed by the contraction force of the second spring 15 itself to pull the limiting plate 7 to abut against the outer wall of the detection equipment body 1.

[0021] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, before use, the operator can install the detection equipment body 1 on the top of the support base 2 and limit the detection equipment body 1 by the limiting plate 7. The second spring 15 pulls the limiting plate 7 to abut against the side wall of the detection equipment body 1 to fix the detection equipment body 1. The specific installation method is as follows: Through the synergistic action of the inner groove, the extension rod 16, the second spring 15 and the limiting plate 7, an elastic clamping structure is formed. Under the contraction force of the second spring 15, the limiting plate 7 can automatically adapt and tightly abut against the side wall of the detection equipment body 1 of different sizes, thereby achieving stable fixation. After installation, pull outwards the pull-out frame 8. The pull-out frame 8 slides out from inside the support base 2. At this time, the operator can insert the reagent tube into the fixing ring 10. The first spring 13 pushes the guide block 14 against the outer wall of the reagent tube through its elastic force, thereby achieving limiting and fixing. The operation is complete. Specifically, an elastic clamping structure is formed through the synergistic action of the inner groove, the extension rod 16, the second spring 15, and the limiting plate 7. During installation, the limiting plate 7, under the contraction force of the second spring 15, can automatically adapt to and tightly abut against the side wall of the detection equipment body 1 of different sizes, thereby achieving stable fixation. The above is the complete working principle of this utility model.
