The invention provides a multifunctional combined magnetic chess box, and belongs to the technical field of chess boxes. Comprising a chess box, a frame is fixedly connected into the chess box, and a containing space on the inner side of the frame is used for arranging chess game scenes or placing chess piece boxes; the
locking mechanism is arranged in the chess box and comprises a pressing plate conical part and an elastic piece, the conical part is fixed to one side of the pressing plate, the elastic piece is used for providing reset elastic force for the pressing plate, and when the chess box is buckled, the conical part is pressed and drives the pressing plate to overcome the elastic force of the elastic piece to move so as to press and fix the chess piece box in the containing space; the chessboard is arranged on the chess box, and a magnetic piece is embedded in the chessboard. By means of the
locking mechanism, when the chess box is buckled, the chess box in the chess box can be automatically pressed, shaking and abrasion of the chess box are effectively prevented, meanwhile, by means of magnetic attraction matching of a socket and an
insertion column and the design of an inner concave part and a clamping part, accidental opening of the chess box can be avoided, and the mounting firmness of the second chessboard is guaranteed.
