The invention discloses a portable mathematical graph theory demonstration frame, specifically relates to the field of demonstration frames, comprising a drawing board, the bottom end of the drawing board is connected with a fixing seat through a fixing component, and a shaft sleeve is sleeved on the bottom end of the fixing seat, The bottom end of the sleeve is fixed with a folding support assembly for supporting the drawing board; the folding support assembly includes a support base that is socketed with the sleeve, and the support base is composed of two connecting rods fixed by hinges, and supports The four ends of the seat are all provided with pin shafts and are fixedly installed with sliders respectively through the pin shafts, and the two ends of the support seat along the transverse direction are respectively fixed with a first support frame and a second support frame; The structure of the frame and the second supporting frame is consistent, and the first supporting frame is composed of a first set of plates and a second set of plates embedded with each other. In the present invention, the entire demonstration frame structure can be folded and stored, and occupies a small area, and is convenient to carry and use.
Description
technical field [0001] The invention relates to the field of demonstration racks, in particular to a portable mathematical graph theory demonstration rack. Background technique [0002] Graph theory is a branch of mathematics that starts with picture As the research object, a graph in graph theory is a graph composed of a number of given points and a line connecting two points. This graph is usually used to describe a certain relationship between certain things, using points to represent things, and using The line connecting two points indicates that there is such a relationship between the corresponding two things. In the process of learning mathematical graph theory, it is often necessary to demonstrate the classic graph theory. [0003] In the teaching process of existing mathematical graph theory, it is often drawn directly on the blackboard, which is not portable enough and inconvenient to use. Contents of the invention [0004] For this reason, the present inventio...
