DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5 A sample detection device for a spectral analysis instrument comprises an analysis box 1, and the analysis box 1 is provided with a flip cover 2 and a detection head 3 for detecting samples;

[0026] The flip cover 2 is equipped with an adjustment structure for adjusting the position of the detection head 3;

[0027] The adjustment structure includes an incomplete ring rod 4 fixedly installed in the flip cover 2, and a guide block 5 is slidably sleeved on the incomplete ring rod 4, a rotating rod 6 is rotatably installed on the flip cover 2, and a traction rod 7 is connected between the rotating rod 6 and the guide block 5. The incomplete ring rod 4 guides the guide block 5 so that the guide block 5 can smoothly pull the fixed rod 8 when moving. Figure 5 As shown, by arranging an incomplete ring rod 4 on the flip cover 2, when the guide block 5 slides with the incomplete ring rod 4 as a fulcrum, the detection angle of the detection head 3 can be adjusted, further improving the flexibility of the detection head 3;

[0028] A fixed rod 8 is fixedly installed on the guide block 5, and a moving block 9 is slidably sleeved on the fixed rod 8. The detection head 3 is arranged on the moving block 9. A telescopic rod 10 connected to the moving block 9 is fixedly installed on the fixed rod 8. The rotating rod 6 is vertically arranged, and a handle is fixedly installed on the rotating rod 6. The detection head 3 and the fixed rod 8 extend to the lower end position in the flip cover 2. When the output end of the telescopic rod 10 is extended or contracted, it can drive the detection head 3 to move, adjust the distance between the detection head 3 and the sample, and further improve the accuracy of sample detection;

[0029] The analysis box 1 is provided with a support platform 18 for supporting the sample through a support member, and the support platform 18 is provided with four clamp plates 22 for preliminary clamping of the bottom of the sample. Figure 5 As shown, four clamp plates 22 are arranged circumferentially, and the clamp plates 22 are arc-shaped structures adapted to the sample, so that the four clamp plates 22 can perform preliminary clamping on the sample;

[0030] The support member includes a support frame 12 fixedly installed in the analysis box 1, and a support rod 13 is fixedly installed on the support frame 12, a sleeve 14 is slidably sleeved on the support rod 13, and a guide rod 17 is fixedly installed on the sleeve 14, and a support platform 18 is arranged on the guide rod 17, and the support rod 13 guides the sleeve 14, so that the sleeve 14 can smoothly pull the guide rod 17 and the support platform 18 when moving;

[0031] An adjustment component for adjusting the height of the sleeve 14 is installed on the analysis box 1;

[0032] The adjustment assembly includes a limit rod 11 fixedly installed in the analysis box 1, and two limit blocks 15 are slidably sleeved on the limit rod 11. The limit rod 11 guides the limit block 15 so that the limit block 15 can smoothly pull the interference rod 16 when moving. The interference rod 16 is connected between the limit block 15 and the sleeve 14. A rack 26 is fixedly installed on the limit block 15. A motor 27 is fixedly installed on the analysis box 1, and a rotating shaft 28 drivingly connected to the two racks 26 is fixedly connected to the output end of the motor 27.

[0033] The limit rod 11 is horizontally arranged below the support platform 18, and the two ends of the abutment rod 16 are respectively connected to the limit block 15 and the middle pin of the sleeve 14, and the rotating shaft 28 is vertically arranged between the two racks 26, and a gear 29 meshing with the two racks 26 is fixedly mounted on the rotating shaft 28. By arranging the gear 29 between the two racks 26, the gear 29 can drive the two racks 26 to move toward or in the opposite direction when rotating;

[0034] When the two racks 26 move toward each other, the distance between the two limit blocks 15 is gradually reduced, thereby lifting the support table 18, so that the operator can ensure the stability of the sample when placing the sample;

[0035] When the two racks 26 move in opposite directions, the distance between the two limit blocks 15 gradually increases, so that the sleeve 14 drives the guide rod 17 and the support platform 18 to move down into the analysis box 1;

[0036] A limiting component for limiting the middle end of the sample is installed on the support table 18;

[0037] The limit assembly includes four guide frames 19 fixedly mounted on the support platform 18, and a support plate is integrally connected to the guide frame 19, a moving rod 20 is movably mounted on the support plate, and a contact plate 21 that resists the movement of the sample is movably mounted on the moving rod 20, a guide block 23 is slidably sleeved on the guide rod 17, and a connecting rod 24 is connected between the guide block 23 and the four moving rods 20, and a telescopic rod 25 connected to the guide block 23 is fixedly mounted on the sleeve 14;

[0038] A long hole for guiding the moving rod 20 and the connecting rod 24 is provided in the guide frame 19. The long hole guides the moving rod 20 and the connecting rod 24, thereby limiting the moving position of the moving rod 20 and the connecting rod 24. The contact plate 21 is an arc-shaped structure matched with the sample, and a soft pad for resisting the movement of the sample is provided on the contact plate 21. The two ends of the moving rod 20 are respectively connected with the support plate and the contact plate 21 pin shaft, and the two ends of the connecting rod 24 are respectively connected with the guide block 23 and the middle end pin shaft of the moving rod 20. By setting the contact plate 21 as an arc-shaped structure matched with the sample, the contact area between the contact plate 21 and the sample can be increased. By setting a soft pad in contact with the sample on the contact plate 21, the sample will not be damaged when it is clamped.

[0039] The guide block 23 is moved downward by contraction of the output end of the telescopic rod 25. When the guide block 23 moves downward, it pulls the moving rod 20 through the connecting rod 24. When the moving rod 20 deflects, it drives the four contact plates 21 to clamp the sample. When the support table 18 is located at the opening of the analysis box 1, the operator can place the sample on the support table 18 and limit the sample through the contact plates 21. The motor 27 is then started to move the support table 18 downward and move the sample to the deep part of the analysis box 1, so that the sample will not tilt when placed, further ensuring the stability of the sample.

[0040] Further, when the abutment plate 21 is deflected, the sample is clamped, and the height of the abutment plate 21 after deflection is higher than the height of the clamping plate 22, so that the clamping plate 22 can initially clamp the bottom of the sample, and the abutment plate 21 can clamp the middle end of the sample after deflection;

[0041] It should be noted that the specific models and specifications of the detection head 3, telescopic rod 10, telescopic rod 25, and motor 27 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0042] The present invention can be explained by the following operation mode:

[0043] Apply pressure to the sample so that the bottom of the sample extends onto the support platform 18, and the clamp plate 22 can initially clamp the bottom of the sample;

[0044] The output end of the telescopic rod 25 contracts and drives the guide block 23 to move downward. When the guide block 23 slides on the guide rod 17, it pulls the connecting rod 24. The connecting rod 24 moves downward to pull the moving rod 20. The moving rod 20 slides in the long hole with the pin point as the fulcrum, so that the moving rod 20 drives the four contact plates 21 to clamp the sample.

[0045] The output end of the motor 27 drives the shaft 28 to rotate, and the shaft 28 drives the gear 29 to pull the two meshing racks 26, so that the two racks 26 move toward or in opposite directions;

[0046] When the two racks 26 move in opposite directions, the limit block 15 is driven to slide on the limit rod 11. When the limit block 15 slides, it pulls the abutment rod 16. When the abutment rod 16 deflects, it presses the sleeve 14, so that the sleeve 14 drives the support platform 18 to slide on the support rod 13, so that the support platform 18 moves down into the analysis box 1;

[0047] The flap 2 is pulled to deflect, so that the flap 2 seals the analysis box 1;

[0048] The detection head 3 detects the sample, and when the position of the detection head 3 needs to be adjusted;

[0049] The handle drives the rotating rod 6 to rotate, the rotating rod 6 drives the traction rod 7 to rotate, the traction rod 7 drives the guide block 5 to rotate on the incomplete ring rod 4, and the guide block 5 adjusts the detection direction of the detection head 3 when moving;

[0050] The output end of the telescopic rod 10 is extended or contracted to drive the moving block 9 to slide on the fixed rod 8, thereby adjusting the distance between the detection head 3 and the sample.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
