Hoisting device used for ultrasonic diagnosis equipment

The invention relates to a hoisting device used for ultrasonic diagnosis equipment. The hoisting device comprises a base, an outer sleeve, a hoisting column, a driving device, an annular transition slide block and rolling shafts, wherein the lower end of the outer sleeve is fixedly connected with the base; the driving device is mounted between the hoisting column and the base; the annular transition slide block is mounted between the hoisting column and the outer sleeve; a first limiting plane is arranged in the peripheral direction of the outer wall of the hoisting column; a second limiting plane is arranged at the corresponding position in the peripheral direction of the inner wall of the outer sleeve; at the positions of the first limiting plane and the second limiting plane, rolling shaft limiting holes are formed in the annular transition slide block; the rolling shaft limiting holes are arrayed on the annular transition slide block along an up-down direction; each rolling shaft is mounted in the corresponding rolling shaft limiting hole; the rolling shafts are in contact and are matched with the first limiting plane and the second limiting plane respectively. When the driving device moves, the hoisting column only can do up-down hoisting movement under the limitation of the first limiting plane, the second limiting plane, the annular transition slide block and the rolling shafts; very few parts are used and the structure is very simple.
