Movable blackboard structure for economic management teaching

Abstract

The invention discloses a movable blackboard structure for economic management teaching, and belongs to the technical field of teaching auxiliary equipment. The movable blackboard structure for economic management teaching comprises a board body, wherein a writing board is arranged on the front side wall of the board body, horizontal sliding grooves are formed in the upper end and the lower end of the front side wall of the board body, clamping sliding blocks are slidably connected into the sliding grooves, a vertically-arranged ferromagnetic metal plate is arranged on the front side of the board body, the ferromagnetic metal plate is fixedly connected with the two clamping sliding blocks, the ferromagnetic metal plate is perpendicular to the two sliding grooves, a bristle layer is attached to the outer wall of the side, close to the board body, of the ferromagnetic metal plate, the bristle layer is attached to the writing board, magnets are fixed to the positions, located on the left side and the right side of the writing board, of the front side wall of the board body, a cavity is formed in the board body, a supporting board is vertically arranged at the center in the cavity, and two sets of electromagnets are fixed to the supporting board. The blackboard can be conveniently and efficiently wiped, the wiping effect is good, the blackboard can be expanded for writing, occupancy of large space is avoided, and the utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of teaching auxiliary equipment, more specifically, to a mobile blackboard structure for economic management teaching. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board surface is hard and is mostly used for teaching. Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. Mostly black, dark green, white or beige. [0003] Most of the existing blackboards are just a single board with a simple structure, and it is very troublesome to wipe after writing. The user needs to use a blackboard eraser to wipe it. Not only the wiping effect is poor, but repeated wiping is required, and the efficiency is low. Small board body, limited writing area and low utilization rate. Contents of the invention [0...
