Abstract

The invention belongs to the technical field of teaching aids, and provides a mathematical teaching blackboard. The mathematical teaching blackboard comprises a blackboard body, wherein rails are arranged on the upper and lower sides of the blackboard; a first vertical rod and a second vertical rod which are connected with the two rails in a sliding manner are arranged between the two rails in a stretching over manner; the second vertical rod can slide circumferentially; a circle drawing cross rod and a line drawing cross rod which can rotate up and down are arranged on the first vertical rod in a sliding manner; a chalk fixing frame is arranged on the circle drawing cross rod; an auxiliary line drawing cross rod capable of rotating up and down is arranged on the second vertical rod in a sliding manner; a blackboard eraser is arranged on one side, which is opposite to the line drawing cross rod, of the second vertical rod; the first vertical rod is of a telescopic rod structure, and two ends of the first vertical rod are hinged to sliding combination parts between the first vertical rod and the rails; and vertical rod slots are formed in the left and right sides of the blackboard body. The mathematical teaching blackboard provided by the invention occupies a small space and is convenient to use; a teacher does not need to carry complicated drawing tools; and the blackboard drawing is more accurate, and the blackboard is more convenient and quicker to erase.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, in particular to a mathematics teaching blackboard. Background technique [0002] In the process of high school mathematics teaching, a large number of geometric drawings need to be drawn. Now, when drawing, mathematics teachers need to carry teaching drawing tools such as triangle rulers and compasses, which are inconvenient to carry and the drawing is not accurate enough; There is a lot of writing on it, the blackboard is wiped more frequently, and the chalk powder is not easy to clean up. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mathematics teaching blackboard which is easy to operate, accurate in drawing and quick in wiping the blackboard in view of the deficiencies in the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a kind of math...
