A driving mechanism capable of driving the movable plate 12 to move in a vertical direction is provided in the body 13. One side of the support plate 8 is connected to the outer side of the movable plate 12. The upper end of the suspension rod 9 rotates and passes through the other side of the support plate 8. The side walls of the suspension rod 9 are fixedly provided with splints 7 corresponding to the upper and lower surfaces of the support plate 8. The distance between a pair of splints 7 is greater than the thickness of the support plate 8. The lower end of the suspension rod 9 is fixedly connected to the upper center position of the hanging basket 2. A bottom plate 1 is provided on the bottom of the body 13 corresponding to one side of the movable plate 12. The water bath 4 is arranged on the bottom plate 1. The beaker 3 is supported by the water bath 4. The part is inserted into the water bath 4, and the beaker 3 is filled with liquid for disintegration time test. The hanging basket 2 can be inserted into the liquid in the beaker 3 and move back and forth vertically. The side wall of the body 13 corresponding to the movable plate 12 is fixedly provided with a fixed plate 15, and the outer end of the fixed plate 15 is provided with a nut 6. The said suspension rod 9 is fixedly provided with a screw sleeve 5, and the screw sleeve 5 is screwed to the nut 6; the side of the splint 7 corresponding to the support plate 8 is provided with a plane bearing 14; an angular contact ball bearing 16 is provided between the suspension rod 9 and the support plate 8; the end face of the movable plate 12 corresponding to the support plate 8 is provided with a socket 11, and the support plate 8 can be inserted into the socket 11, and the movable plate 12 and the support plate 8 are fixed by squeezing the top with fastening nails 10.

Here, the suspension rod 9 is limited to the upper and lower sides of the support plate 8 by a pair of clamps 7, ensuring that the suspension rod 9 can be driven to move vertically when the support plate 8 moves vertically. Since the screw sleeve 5 on the suspension rod 9 is screwed to the nut 6 set at one end of the fixed plate 15, the suspension rod 9 can be rotated under the limit of the nut 6 while moving vertically, thereby achieving the purpose that the hanging basket 2 can not only move vertically, but also rotate while moving vertically. The screw sleeve 5 here refers to that it is sleeved on the suspension rod 9, and the outer wall is provided with a spiral groove, which is used in conjunction with the nut 6. The suspension rod 9 is rotatably connected to the support plate 8, and the distance between the pair of clamping plates 7 is greater than the thickness of the support plate 8, ensuring that the rotation of the suspension rod 9 is not affected. In the present utility model, the hanging basket 2 can not only move vertically, but also rotate while moving vertically, so that the medicine in the hanging basket 2 can simulate the peristalsis of the gastric fluid as much as possible, thereby improving the accuracy of the drug disintegration time detection.

[0019] Among them, a plane bearing 14 is provided on the side of the clamping plate 7 corresponding to the support plate 8 to reduce the friction between the clamping plate 7 and the support plate 8.
