Abstract

The invention discloses a demonstration system for experiment instrument development for experiment teaching, and the system comprises a sleeve rod, an inner cavity of the sleeve rod is slidably connected with a supporting rod, the upper end surface of the supporting rod is fixedly connected with a placement plate, the inner side wall of the sleeve rod is fixedly connected with a substrate, the upper end surface of the substrate is symmetrically and fixedly connected with bosses, the front end faces of the bosses are rotatably connected with a rotating shaft in a penetrating mode, the rear end face of the sliding shaft is rotatably connected with the lower end face of the supporting rod, the front, rear, left and right side walls of the sleeve rod are fixedly connected with baffles, the front and rear end faces of the baffles are provided with protection mechanisms, and the outer side walls of the baffles are slidably connected with protection frames through sliding grooves matched with sliding blocks. The invention relates to the technical field of demonstration platforms. The demonstration system for experiment instrument development for experiment teaching solves the problems that an existing demonstration system for experiment instrument development for experiment teaching is inconvenient to temporarily limit and fix placed experiment instruments and is inconvenient to protect and block the experiment instruments when the experiment instruments are not used.

Description

technical field [0001] The invention relates to the technical field of demonstration platforms, in particular to a demonstration system for developing experimental instruments for experimental teaching. Background technique [0002] At present, in the learning process of students, some physical experiments are used to understand the working principle and working process, and teachers are often required to do experimental demonstrations to increase students' understanding and memory of physical principles, which is convenient for students' learning and the development of experimental instruments and improvements, so it needs to be demonstrated with the help of a demonstration platform system when using it. [0003] The existing device used for the demonstration system for the development of experimental equipment for experimental teaching is inconvenient to temporarily limit and fix the placed experimental equipment, and it is easy to be bumped and dumped during the experimen...
