Problems solved by technology

[0018] Most of the existing jigsaw puzzles are spliced ​​on the desktop when they are used. Putting the light and small jigsaw components in the right position requires careful and repeated adjustments. If there is a slight vibration after splicing, the graphics will collapse, that is, the graphics are not stable enough. Use inconvenient

Abstract

The invention discloses a tangram convenient to splice and having a locating function. The tangram is composed of a check chessboard and tangram components. The front of the check chessboard is provided with continuously equal check arrays drawn with straight line sections, the check side length is equal to the right angle side length of a minimum triangular component in the tangram, checkers are provided with protrusions, and the tangram components are provided with grooves. Under various effective placing states formed by coinciding of tangram component vertexes and checker vertexes, the protrusions can be accommodated by the grooves to be placed stably, and the tangram components are fixed to the corresponding positions of check chessboard plane through conterlocking of the protrusions and the grooves. The tangram has the advantages that when the lattice point tangram is spliced, a user can focus on the abstract thinking process of achieving game or teaching goals more conveniently, and operation times and time of adjusting the tangram components are reduced; by means of the guidance of graticule lines, visual assistance is provided, splicing difficulty can be reduced, and the tangram is favorable for the user's exploration of unknown lattice point tangram patterns.

Description

technical field [0001] The invention relates to an educational toy, in particular to a jigsaw puzzle with convenient splicing and positioning functions. Background technique [0002] The jigsaw puzzle evolved from the Yan (Yan) figure in the Song Dynasty. In addition to being widely used as a toy, it also contains many interesting and profound mathematical problems, involving combinatorics, geometry, graph theory, and equal-area transformation. . [0003] The most important application occasions of traditional jigsaw puzzle toys include: children imitate or explore various aesthetic shapes when playing games; teachers use them as auxiliary teaching aids for students to understand the relationship between geometric figures, etc. Tangram puzzles consist of seven building blocks in five shapes ( figure 1 ) [0004] The following first introduces the academic research results made by mathematicians in the field of jigsaw puzzles, explains some basic concepts related to jigsaw...
