The invention discloses a structure for stabilizing an analytical instrument lifting mechanism. The structure comprises a rack, an upper cavity body, a lifting mechanism fixing bracket, a movable arm and air pressure supports, wherein the upper cavity body is connected with the movable arm; the number of the air pressure supports is two; the air pressure supports are arranged in a front and back symmetrically distributed manner; fixed ends of the air pressure supports are fixedly connected with the rack; movable ends of the air pressure supports are fixedly connected with the movable arm; and the middle of the movable arm is slidingly connected with the lifting mechanism fixing bracket. The structure further comprises a bearing movable fixing bracket, wherein the bearing movable fixing bracket is fixedly connected with the rack; a long waist-shaped hole is formed in the bearing movable fixing bracket; sliding bearings are symmetrically arranged at the front end and the back end of the upper cavity body, and are in sliding fit with the long waist-shaped hole of the bearing movable fixing bracket; and one of the sliding bearings comprises a lead screw, a bearing body, a locating check ring and a lock nut that are sequentially combined. The structure has the advantages that the upper cavity body can be operated and moved more quickly and conveniently and has good sliding property and stability, so that stabile translation operation can be carried out smoothly, and the detection accuracy of an analytical instrument can be facilitated.
