Abstract

The utility model discloses a magnetic writing board provided with a handwriting erasing mechanism, and belongs to the technical field of teaching appliances. The magnetic writing board comprises a tank, wherein a magnetic display board is fixed on the front surface of the tank, the handwriting erasing mechanism is mounted in the tank and comprises guide rails fixed in the tank, the guide rails are arranged in the length direction of the magnetic display board, a sliding block is glidingly mounted on the guide rails, a magnetic stripe support is fixed in the front of the sliding block, magnetic stripes are fixed on the magnetic stripe support and close to the back of the magnetic display board, the length of each magnetic stripe is equal to the width of the magnetic display board, and a linear motion transmission mechanism is connected onto the sliding block and driven by a driving device. The magnetic writing board provided with the handwriting erasing mechanism adopts the magnetic stripes and the magnetic erasers, is free from dust pollution and is environment-friendly and healthy; and a mechanical and electronic integration technology is applied comprehensively, so that handwriting on the whole board can be rapidly erased, the remote-control and manual point control mode saves the physical strength, the manual mode does not require electric power supply, and the magnetic writing board can be popularized and used in the area short of electric power.

Description

technical field [0001] The invention relates to a magnetic writing board for demonstration, which belongs to the technical field of teaching appliances. Background technique [0002] At present, the writing boards used for demonstration and teaching are mainly blackboards, which can be roughly divided into three categories in terms of production materials and usage principles: [0003] One is an ordinary blackboard. In terms of production materials, green board is currently the most widely used. It is composed of surface panels, sandwich materials, and back panels, and is coated with a layer on the surface, which is black and green, hence the name. Secondly, glass blackboards are used more. This kind of blackboards is made of glass plates of 5mm and above. The surface is finely processed, and the back is painted with black paint. There are relevant production standards. In addition, in some underdeveloped areas, there are wooden blackboards and cement blackboards. No mat...
