Automatic push-pull device of traditional Chinese medicine box of automatic medicine cabinet

The invention relates to an automatic push-pull device of a traditional Chinese medicine box of an automatic medicine cabinet. The automatic push-pull device comprises a wallboard, a transmission mechanism, a push-pull device and an auxiliary mechanism, wherein the transmission mechanism is arranged on the wallboard, and the push-pull device is flexibly connected with the transmission mechanism through a push board, characterized in that a wheel shaft (2) of the transmission mechanism drives a transmission wheel (3) and the push board (9) on a transmission belt (chain) (8) to make rectilinearmovement rightwards or leftwards; simultaneously, the transmission wheel (3) rotates around the wheel shaft (2), so that the transmission belt (chain) (8) and the push board (9) fixed to the transmission belt (chain) (8) move rightwards or leftwards; and the push board (9) generates two superposed movements to realize long rectilinear movement of the push-pull device twice as long as the moving distance of a bracket. The automatic push-pull device has a compact structure, fewer spare parts, simple process, novelty and uniqueness, fully saves the space in the medicine cabinet, is easy to manufacture, and obtains double long-distance movement externally by short-range movement in the structure.
