[0026] Compared with the prior art, the present invention has the following beneficial effects: the multi-channel infrared spectrum analysis sample cell is provided with a plurality of adjustment components inside the sample cell body, so that the position of the sample placement can be adjusted according to the type and material of the sample to be analyzed, and the distance between the sample and the light source can be adjusted, so that the light can be perpendicular to the sample without blocking the light, thereby improving the accuracy of sample analysis and measurement and enhancing practicality;

[0027] 1. Several adjustment components are set inside the sample pool body. Samples of different types and materials can be placed through several placement seats. The spectrometer can be installed through the mounting groove, and multi-channel analysis and measurement of the sample can be realized. Then, the position of the sample after placement and the characteristics of the sample itself can be determined by rotating the rotating rod to drive the threaded rod to rotate. After the threaded rod rotates, it can be moved through the threaded connection of the threaded sleeve. After the threaded rod moves, it can drive the support frame to move, so that the two fixed rods move. After the fixed rod moves, it can drive the movable frame to move, so that the placement seat can be driven to move. The distance between the sample and the spectrometer can be adjusted separately. If you want to adjust the height and distance of the sample at the same time, you can push the mounting plate and rotate the rotating rod. After the mounting plate moves, it can drive the push rod to move, so that the first movable rod can be driven to slide in the first movable groove, so that the support ring can be driven to move. The movable block is then driven to move by cooperation with the fixing ring and the annular groove. After the movable block moves, the telescopic spring is stretched, and the limit rod can be driven to slide on the mounting block, thereby driving the output shaft to move. After the output shaft moves, it can be inserted into the connecting groove on the connecting shaft. The cooperation of the output shaft and the connecting shaft makes the threaded rod rotate to drive the connecting shaft to rotate. After the connecting shaft rotates, it can drive the screw to rotate through the meshing of the first bevel gear and the second bevel gear. After the screw rotates, it can drive the movable frame to rise and fall through the threaded connection with the movable frame, so that the height of the placement seat can be adjusted, and the height and position of the placement seat can be adjusted at the same time. The adjustment component can be used to adjust the position of the sample placement according to the type and material of the analyzed sample, and the distance between the sample and the light source can be adjusted so that the light can be perpendicular to the sample without blocking the light, thereby improving the accuracy of sample analysis and measurement and improving practicality.

[0028] When the second movable rod is moved, the second movable rod can be driven to slide in the second movable groove, so that the ball on the second movable rod abuts against the movable ring. At this time, the two rubber blocks abut against the sample pool body, and the compression spring is in a compressed state, which can exert a reaction force on the rubber block. The friction force of the rubber block can prevent the threaded sleeve from rotating with the threaded rod, and the height and position can be adjusted at the same time. If you only need to adjust the height of the placement seat at this time, you can continue to push the mounting plate to move, so that the two push rods continue to move, and the first movable rod continues to move to make the output shaft slide in the connecting groove, and the movement of the second movable rod can push the movable ring to move through the ball. After the movable ring moves, it can drive the two sliding rods to move, and after the sliding rod moves, it can drive the rubber block to move, and the compression spring can be continued to be compressed so that one side of the rubber block leaves the sample pool body. At this time, the threaded sleeve can lose its limit, and then the rotation of the threaded rod may drive the threaded sleeve to rotate together, which is convenient for subsequent adjustment of the height of the placement seat;

[0029] 3. The two second movable rods push the movable ring to move, and then drive the sliding rod to move. After the sliding rod moves, it drives the column rod between the support blocks to move. After the column rod moves, it can push the two movable rods closer to each other through the sliding connection with the inclined groove. After the movable rods are close to each other, the rubber sleeve is wrapped around the outside of the threaded rod. After the threaded rod rotates, the friction between the rubber sleeve and the threaded rod can drive the rubber sleeve to rotate, so that the movable ring rotates, and then the threaded sleeve can rotate with the threaded rod. The height of the placement seat can be adjusted separately, and then when measuring different samples, the height of the sample can be adjusted according to the characteristics of the sample, so that the light emitted by the spectrometer can be perpendicular to the sample, which can improve the accuracy of the sample measurement and improve practicality.

Then, according to the position of the sample after placement and the characteristics of the sample itself, the rotating rod 203 can be rotated to drive the threaded rod 202 to rotate. After the threaded rod 202 rotates, it can be moved through the threaded connection of the threaded sleeve 201. After the threaded rod 202 moves, it can drive the support frame 212 to move, so that the two fixed rods 213 move.

[0058] When the push rod 216 moves to adjust the height of the placement seat 103, it can drive the second movable rod 232 to slide in the second movable groove 231, so that the ball 2321 on the second movable rod 232 abuts against the movable ring 230. At this time, the two rubber blocks 236 abut against the sample pool body 1, and the compression spring 235 is in a compressed state, which can apply a reaction force to the rubber block 236. The friction force of the rubber block 236 can prevent the threaded sleeve 201 from rotating together with the threaded rod 202, and the height and position can be adjusted at the same time. If you only need to adjust the height of the placement seat 103 at this time, you can continue to push the mounting plate 217 to move, so that the two push rods 216 continue to move, the first movable rod 219 continues to move to make the output shaft 227 slide in the connecting groove 228, and the movement of the second movable rod 232 can push the movable ring 230 to move through the ball 2321, and after the movable ring 230 moves, it can drive the two The second movable rod 232 pushes the movable ring 230 to move, and then drives the sliding rod 233 to move. After the sliding rod 233 moves, it drives the column 238 between the support block 237 to move. After the column 238 moves, it can push the two movable rods 239 to move closer to each other through the sliding connection with the inclined groove 240. After the movable rods 239 move closer to each other, the rubber sleeve 241 is wrapped around the outside of the threaded rod 202. After the threaded rod 202 rotates, the friction between the rubber sleeve 241 and the rubber sleeve 241 can drive the rubber sleeve 241 to rotate, so that the movable ring 230 rotates, and then the threaded sleeve 201 can rotate together with the threaded rod 202, and the height of the placement seat 103 can be adjusted separately.
