Technical practical training equipment experimental device based on block chain

The utility model discloses a technical practical training equipment experimental device based on a block chain, which structurally comprises a protective shell, an experimental engine base, a box body, an experimental core plate, a connecting bottom plate, a box cover and a hinge, and has the following beneficial effects: the box body and the box cover are respectively provided with a closed backing ring I and a closed backing ring II; and the two closed backing rings adopt concave-convex surface structures which can be matched with each other, and a compression spring is arranged at the assembly position of the two closed backing rings for movable jacking, so that the closed telephone can be corrected when the cover is closed due to the mobility of the spring while the jacking pressure degree of the closed backing rings is ensured, and the closed telephone can be conveniently used in a closed manner. By arranging the test assembly bottom plate jacked up by the compression spring in the box body to be matche
