Description

Technical Field

[0001] The present application relates to the technical field of geography teaching aids, and more specifically to a spherical puzzle. Background Art

[0002] Jigsaw puzzles are a type of DIY toy that combines entertainment, hands-on play, and educational opportunities. Currently, most people use flat puzzles, which are composed of several smaller flat patterns to create a larger flat pattern. These flat puzzles have evolved into three-dimensional puzzles. Compared to flat puzzles, three-dimensional puzzles are more interesting and playable, adding a variety of fun to life while also shifting the two-dimensional thinking practiced in puzzles to a three-dimensional one. This is especially true for map puzzles, where flat patterns fail to accurately represent the map's position on the Earth, hindering the user's understanding of geography. The commonly used globe consists of a sphere with a map attached and a sphere stand. The sphere is often molded in one piece, cannot be disassembled, and is bulky, taking up a lot of space and making it difficult to carry or store. This makes it difficult to use and less engaging, making learning about the Earth rather boring for students. Therefore, the utility model patent with the publication (announcement) number CN218568259U discloses a 3D stereo puzzle-type globe, including a base, an arched bracket connected to the base, a rotating shaft movably connected to the arched bracket, and a globe body fixedly connected to the rotating shaft, the globe body including a spherical bracket, a basic splicing block that is inserted and covered outside the spherical bracket to form a spherical base surface, and a land splicing block that is inserted and covered outside the spherical base surface; in this technical solution, the surface of the globe body is spliced by detachable basic splicing blocks and land splicing blocks, which improves the fun, but the basic splicing blocks need to be spliced and inserted on the spherical bracket, and the spherical bracket has a fixed size and a large volume, which has the problems of occupying a large space and being inconvenient to carry and store. In response to the above-mentioned problems, a utility model patent with the publication (announcement) number CN204121770U discloses an earth ritual puzzle, including a six-way connector, a mounting clamp and a frame rod. There are twelve six-way connectors and thirty frame rods. The frame rods are interconnected through the six-way connectors to form a regular icosahedron. The frame rods are each installed with two mounting clamps with clamping directions facing different sides. Jigsaw pieces are arranged on each face of the regular icosahedron, and the puzzle pieces are positioned by a mounting clamp on three adjacent frame rods. In this technical solution, the puzzle pieces are positioned by the mounting clamps, and the exposed mounting clamps are not only aesthetically pleasing, but also the six-way connectors, frame rods and mounting clamps need to be assembled separately, which has problems such as many assembly steps and complicated assembly.
