Abstract

The invention provides a multifunctional information management teaching device, which comprises a bottom plate, moving wheels, telescopic pipes, a telescopic rod, a U-shaped frame, a connecting rod,a protection plate, a placement plate, a rotatable fixing seat structure, a projection writing board structure, an auxiliary supporting frame structure, a movable cleaning frame structure, a shell, astorage battery and a driving switch. The moving wheels are installed on the periphery of the lower surface of the bottom plate through bolts. The telescopic pipes are welded to the left side and theright side of the upper surface of the bottom plate correspondingly. The telescopic rods are welded to the left side and the right side of the lower end of a U-shaped frame correspondingly, the telescopic rods are inserted into the telescopic pipes, and meanwhile the connecting positions of the telescopic rods and the telescopic pipes are fixed through bolts. The device has the beneficial effectsthat through the arrangement of a rotatable fixing seat structure, a clamping plate is contracted under the action of external force during rotation, so that the clamping plate can be clamped throughthe clamping teeth for fixed use when the clamping teeth rotate or do not rotate, and then the clamping plate can be conveniently rotated and fixed at a specified angle for use.

Description

technical field [0001] The invention belongs to the technical field of information management teaching, and in particular relates to a multifunctional information management teaching device. Background technique [0002] In the process of teaching and teaching, due to the limited size of the blackboard board, additional teaching boards are often needed during the teaching process to expand the limited blackboard, or hang wall charts on the teaching board to assist in teaching. The existing teaching aids The device is provided with a column for support. The upper end of the column is provided with a board. The board can be set vertically for additional writing or hanging, and the board can be set horizontally to place teaching aids. In order to facilitate movement, it is usually set on the base of the column. universal wheel. [0003] However, the existing information management teaching device still has the problems of being inconvenient to adjust and use, the device has po...
