Description

Technical Field

[0001] The utility model belongs to the technical field of learning tools, in particular to a kind of Huarongdao magnetic chess pieces. Background Art

[0002] Huarong Dao includes a chessboard and several chess pieces. There is a slide on the chessboard, and each chess piece is slid in the slide. Each chess piece is marked with different display content. It is necessary to use as few steps as possible and as short a time as possible to rearrange the blocks on the chessboard (numbers, pictures, text, chemical elements, etc.) in order from left to right and from top to bottom.

[0003] However, the chessboard and chess pieces of the existing Huarongdao on the market are connected by magnetic attraction. Specifically, a magnetic attraction block is usually installed inside the chess piece, and a magnetic attraction member (such as a magnet or a magnetic conductive sheet) is arranged on the back of the chessboard. The magnetic attraction makes the chess piece difficult to slide.

[0004] like Figure 1 As shown, the existing chess pieces are usually connected together through four sets of guide pins a and guide sleeves b. When engaging, each guide pin a needs to be placed in the corresponding guide sleeve b respectively before engaging, and the efficiency of the engaging operation is low. In addition, the contact between the traditional guide pin a and the guide sleeve b is a smooth curved surface, which is easy to loosen when subjected to external force. If loosening occurs, the magnetic attraction part set at the middle position C is easy to dislocate.

[0005] In view of this, the inventor of this case conducted in-depth research, which resulted in the creation of this case. Utility Model Content
