This utility model relates to the technical field of shelves, in particular to a lifting storage mechanism. The lifting storage mechanism includes a frame body, a lifting platform, a guiding assembly and a resetting assembly, wherein the guiding assembly is provided with a first sliding structure, a second sliding structure and a third sliding structure, which are respectively connected to the resetting assembly and the lifting platform to cooperate with the resetting assembly and drive the lifting platform to go up and down in the accommodating cavity. The lifting storage mechanism disclosed by the utility model is simple in structure and reasonable in design. During use, when articles on the lifting platform are gradually taken away, the lifting platform is lifted up along with three groups of sliding structures under the action of pulling force of the resetting assembly. In a lifting process, the three groups of the sliding structures can achieve the effects of guidance, limitation and stable support so that the lifting platform is stressed more uniformly to prevent the situations of inclination and the like, and ensure that the lifting process is smoother and more stable to meet lifting requirements well.
