Description

Four star appearance teaching aids that can assemble Technical Field The utility model belongs to the technical field of teaching aids, and particularly relates to a spliced four-star instrument teaching aid. Background In astronomical teaching and science popularization fields, a four-star instrument teaching aid is often used for demonstrating the operation rules of golden stars, mars, wooden stars and earth stars, and helps learners to understand the position change of celestial bodies. However, the conventional four-star instrument teaching aid has the following defects: The structure is fixed, interactivity is lacking, the existing four-star instrument is of an integrated forming structure, a learner cannot deeply understand the internal structure and the working principle of the four-star instrument through manual assembly, the teaching process is lack of participation, and learning interest is difficult to excite. The teaching aid has the advantages of single function and limited demonstration effect, and part of the teaching aid can only demonstrate the running track of a single star, or can demonstrate multiple stars, but has complex scale design and inconvenient operation, and cannot intuitively present the corresponding relation between the dynamic position of the star and time and date, so that the teaching efficiency is reduced. The applicability and the safety are insufficient, the edges of parts of some teaching aids are not polished, scratches are easily caused during assembly, the stability of joints is poor, the use experience is affected, meanwhile, the functional design cannot meet the requirements of different learning scenes, and diversified teaching targets are difficult to meet. . Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a spliced four-star instrument teaching aid, which solves the technical problems of fixed structure, lack of interactivity, single function and limited demonstration effect of the traditional teaching aid. The utility model adopts the scheme that the spliced four-star instrument teaching aid is characterized by comprising the following components: the detachable and assembled part assembly comprises a cross buckle, a civil star plate, a fire star plate, a pointer plate, a gold star plate and a four-star instrument plate; the civil star plate is the largest plate body, the fire star plate, the pointer plate, the golden star plate and the four star instrument plate are sequentially stacked on the civil star plate from bottom to top, and the centers of the plate bodies are fixedly connected through the cross buckle; The dynamic position prediction device comprises a plurality of discs, wherein each disc is provided with a scale mark, each scale mark comprises a year scale, a date scale and a direction indication scale, and the scale marks are used for realizing the dynamic position prediction function of golden stars, mars, wooden stars and earth stars through scale coordination among the discs. Preferably, the edges of the part assembly are polished. Preferably, the inner ring of the civil star is provided with a year scale, the star is provided with a specified date scale, the star is provided with a triangular scale, the four star instrument is provided with a year scale triangle, and the dynamic position of the star is read by aligning the triangular scale of the star with the year scale triangle of the four star instrument. Preferably, the pointer disc is provided with scale marks, the scale marks are aligned with the 'earth' scale marks on the golden star disc by rotating the pointer disc, the target date scale marks on the four-star instrument disc are parallel to the direction lines of the 'earth+' mark pointing to the 'Mars+' mark, and the constellation positions of the yellow tracks where the Mars are located are read. Preferably, the scale line of the pointer disc points to the corresponding year scale of the wood star or the earth star on the civil star disc by rotating the pointer disc, and the position of the wood star or the earth star in the yellow road constellation is determined by combining the indication red line on the civil star disc. The beneficial effects are that: 1. The interaction and structure cognition are enhanced, namely, a detachable and assembled part assembly is adopted, so that a user needs to assemble parts such as a cross buckle, a civil star plate, a spark star plate and the like by hand, and the internal structure of the teaching aid and the superposition logic of all the plate bodies are deeply understood. The assembly process not only improves the participation of learning, but also can intuitively display the mechanical principle of the four-star instrument, thereby being beneficial to the learner to establish space thinking and deepen the cognition of astronomical teaching aid structures. 2.
