Teaching demonstration platform

Abstract

The invention relates to the technical field of teaching tools, especially a teaching demonstration platform. The platform comprises an operating platform, and the top of the operating platform is coaxially provided with a placement groove. The interior of the placement groove is rotatingly connected with a support seat through a rotating shaft, and the top and bottom surfaces of the support seatare respectively in fixed connection with a first experiment table and a second experiment table. The other end of the rotating shaft is connected with two limiting blocks in a symmetric and fixed manner, and the two limiting blocks are parallel to the top surface of the support seat. The top of the operating platform is provided with a bar-shaped groove, and one side, close to the placement groove, of the bar-shaped groove is communicated with an opening. A side wall of the opening wall is symmetrically provided with a groove, and the rotating shaft passes through the opening to extend to thebar-shaped groove. Moreover, the rotating shaft is connected with a cross plate through a bearing seat, and the cross plate is connected in the bar-shaped groove through a plurality of electric telescoping rods. According to the invention, the support seat can achieve the rotating and switching of the first and second experiment tables for use under the action of the electric telescoping rods andthe rotating shaft, so as to select different experiment tables according to the requirements of application.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a teaching demonstration platform. Background technique [0002] Mechanism cognition experiments in the course of mechanical principles generally use mechanism display cabinets or mechanism models to enhance students' perceptual knowledge of mechanism connections and movements. Traditional mechanism display cabinets have many types of demonstration mechanisms, but their large size is not conducive to classroom demonstrations. Theoretical teaching and practical teaching cannot Good unification is achieved, the organization model is small in size, but the demonstration organization is relatively single, and students' understanding of the organization is not comprehensive enough. For this purpose, we propose a teaching demonstration table. Contents of the invention [0003] The object of the present invention is to propose a teaching demonstration platform in order to...
