Abstract

The present invention discloses a mechanical teaching aid convenient for the students to demonstrate. The mechanical teaching aid comprises two supporting plates, the tops of the supporting plates are fixedly connected with the supporting legs, and the tops of the supporting legs are fixedly connected with a connecting casing. The bottom of the connecting casing is movably connected with a U-shaped block, an inner cavity of the U-shaped block is connected with a pulley movably via a rotating shaft, the surface of the pulley is movably connected with a traction belt, and the two ends of the traction belt both extend to the bottom of the pulley. According to the present invention, by rotating a rotating handle to drive a rotating rod and a gear to rotate, and by the rotation of the gear, a toothed plate can be moved rightwards to an inner cavity of a fastening groove, and then a pulley block demonstration test can be operated. After an experiment is ended, by rotating the rotating handle reversely, the toothed plate can be taken out from the inner cavity of the fastening groove. The experiment process is not limited by the places, the operations are very convenient, the interests of the students are enhanced, and naturally, the academic records of the students are improved.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a mechanical teaching aid which is convenient for students to demonstrate. Background technique [0002] Teaching aids are models, real objects, charts, slides, etc. used to explain something, including teaching equipment, teaching instruments, training equipment, educational equipment, experimental equipment, teaching specimens and teaching models, etc. Among them, the pulley block demonstration experiment is a middle school experiment. An extremely important experiment, the experiment process is vivid, vivid and interesting, and is deeply loved and concerned by students. Every school will demonstrate the pulley block experiment to students. However, the operation process of the traditional pulley block experiment is limited by the location, so it cannot be done without a support at will. The operation process is very inconvenient, which will not only affect the effec...
