Embodiment Construction

[0027] The following is attached Figure 1-4 The present invention is further described in detail.

[0028] A kind of multi-functional blackboard, it comprises the blackboard that is fixed on the wall 11 by support 1 and is respectively arranged on the projection mechanism and the wiping mechanism of blackboard both sides by suspension device; Described blackboard comprises: rectangular steel plate layer 21, is laid on The glass writing layer 22 on the outer rough surface and a plurality of LED lamp beads 23 distributed on the steel plate layer 21 in a matrix, the LED lamp beads 23 pass through the steel plate layer 21 and conflict with the glass writing layer 22; the evenly distributed LED lamp beads 23 will On the glass writing layer 22, a uniform array of light spots is displayed, so that there is a good basis for drawing straight lines, oblique lines, and circles when using it. It can quickly divide the area of ​​the blackboard and easily draw tables, especially for establ...

Abstract

The invention relates to a multifunctional blackboard. The multifunctional blackboard comprises a blackboard fixed on a wall by a support and a projector mechanism and an erasing mechanism which are respectively arranged at two sides of the blackboard by a suspension device. The multifunctional blackboard is mainly formed by three parts, LED lights are embedded to a steel deck and are uniformly distributed in a matrix form, and when in use, positioning can be carried out according to light spots shown by a glass writing layer, so that use of ruler set square can be reduced, and board writing efficiency can be improved; light of the LED lights cannot affect the display effect of black and white after passing through the roughened glass writing layer; the multifunctional blackboard is further provided with a dustless module for erasing the blackboard and a releasing module for a projection screen, and therefore, the multifunctional blackboard is good in integrity and integrates multiple functions.
