[0043] The four cross columns 234 of the four clamping blocks 23 are inserted into the corresponding cross holes 225 respectively, and the front clamping blocks 232 are ensured to face the center of the rotating disc 21. The push rod 25 is inserted into the push rod hole 212. At this time, under the pushing force of the compression spring 24, the four clamping blocks 23 are all at the position closest to the center of the rotating disc 21 in the corresponding guide groove 211. The movable plate 31 of the sampling frame 3 is lifted upward from the sampling groove 12. At this time, the folding device of the sampling frame 3 is in the folded state, and the upper folding rod 33 is located in the middle position of the two side plates 341 of the lower folding rod 34. Due to the assembly limitation of the folding device, at this time, the upper hinge shaft 342 is located at the end away from the hinge hole 331 in the movable slot 332 of the upper folding rod 33, and the front and rear corresponding folding devices are folded towards the horizontal center position of the sampling groove 12 under the limitation of the limiting plate 344. In the process of lifting the sampling frame 3, the upper shaft seat 32 at the bottom of the movable plate 31 drives the upper folding rod 33 to rotate around the hinge column, the upper folding rod 33 drives the lower folding rod 34 to rotate around the upper hinge shaft 342, and the lower hinge shaft 343 rotates in the lower shaft seat 121 at the same time, until the movable plate 31 is completely lifted to the highest position, at this time, the upper folding rod 33 is collinear with the lower folding rod 34, the length direction of the movable slot 332 is collinear with the lower folding rod 34, and the upper hinge shaft 342 is located at the lowermost position of the movable slot 332. The movable plate 31 is moved vertically downward, driving the upper folding rod 33 to move downward, and the upper hinge shaft 342 moves upward in the movable slot 332 at the same time, until the upper hinge shaft 342 moves to the end of the movable slot 332 closest to the hinge hole 331, at this time, the side surface of the upper folding rod 33 close to the horizontal center position of the sampling groove 12 contacts with the limiting plate 344, and the upper folding rod 33 cannot rotate under the cooperation of the upper hinge shaft 342. Since the lower folding rods 34 of the front and rear corresponding folding devices are symmetrically arranged, each folding device cannot rotate, so that the movable plate 31 is limited in the stable position. At the same time, each pipe groove 123 on the supporting table 122 corresponds to the pipe hole 311 on the movable plate 31 in the vertical direction. At this time, the sampling device is as follows Figure 1The assembly is complete when the sample tubes are unfolded and in working condition. The sample tubes are removed from the storage box 13 and inserted into the tube holes 311, resting at the bottom of the tube groove 123. Under the combined constraint of the tube holes 311 of the movable plate 31 and the tube groove 123 of the support platform 122, the sample tubes are stably placed on the sampling rack 3 without tipping over. The turntable 21 of the rotating device 2 is rotated horizontally by the lever 25. Guided by the guide groove 211, the circular column 223 drives the clamping block assembly structure to move longitudinally deeper along its corresponding square holes 113. The limiting block 222 compresses the compression spring 24 until the circular column 223 moves to the farthest point in the corresponding guide groove 211, away from the center of the turntable 21. Place the medicine bottle containing the liquid medicine on the turntable 21, and slowly release the lever 25. Under the elastic force of the compression spring 24, the limiting block 222 is pushed, causing the clamping block assembly structure to extend longitudinally along the corresponding square hole 113. The clamping block 23 moves towards the center of the turntable 21. At the same time, the circular column 223 drives the turntable 21 to rotate under the guidance of the guide groove 211. When the medicine bottle is placed randomly and is not in the center of the turntable 21, one of the clamping blocks 23 will contact the medicine bottle first and push the medicine bottle towards the center of the turntable 21 during the rotation of the turntable 21 until all the clamping blocks 23 contact the medicine bottle. At this time, the medicine bottle is in the center of the turntable 21. Since the front clamping block 232 is made of rubber material with granular protrusions, it can play a buffering role. Under the elastic force of the compression spring 24, the medicine bottle is firmly clamped on the turntable 21 without damaging the packaging of the medicine bottle.

[0044] The motors of the translation mechanism 4 are started. Driven by the motors and lead screws, the sampling and titration device 5 is quickly positioned at the medicine bottle. Under the action of the hydraulic cylinder 53, the sample of the medicine to be tested is taken from inside the medicine bottle. Then, the sampled medicine is titrated into the test tube under the action of the translation mechanism 4 and the hydraulic cylinder 53, thus completing the sampling of the medicine to be tested.

[0045] When folding up the sampling device, reverse the installation process described above to fold the device. Pull out handle 6 to bring the sampling device to the desired position. Figure 2 The initial state shown indicates that the sampling device can be carried away from the sampling location.

[0046] The utility model discloses adopt detachable clamping block combination structure, collapsible sampling frame structure, rotatable folding translation mechanism 4 and sampling titration device 5, the structure of hidden handle 6 etc., make the whole structure of medicine quality detection sampling device can realize quick folding and assembly, and the sampling device is convenient for carrying, and the sampling and detection of direct sampling site of convenient detection personnel are carried out, avoid the pollution risk that sampling medicine shifts, can adapt to the medicine bottle of different diameter size packing, and can quickly with different size medicine bottle all be positioned in the center position of rotating device 2, the sampling device is convenient for quick positioning, and it is convenient to sample quickly, improve sampling efficiency, can stably fix medicine bottle, sampling tube on sampling device, increase the stability of equipment sampling process, avoid the risk of equipment pollution in the sampling process because of medicine bottle, sampling tube dumping, and through reasonable arrangement structure position, increase the storage structure on sampling device, it is convenient to store and carry sampling tube 52 with sampling tube, improve sampling efficiency.

[0047] Finally, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
