Abstract
The invention discloses a blackboard good in use effect. The blackboard comprises support plates and is characterized in that a first electric telescopic rod is fixedly connected to the top of each support plate, a transverse rod is fixedly connected to one side of the output end of each first electric telescopic rod, a support block sleeves the surface of each transverse rod, a vertical plate isfixedly connected to the top of each support block, and a support rod is fixedly connected to the front side of each support block. The blackboard has the advantages that by the coordination of the support plates, the first electric telescopic rods, the transverse rods, the support blocks, the vertical plates, the support rods, first support blocks, a blackboard body, second support blocks, secondelectric telescopic rods, an eraser box, a placing plate, a chalk box, a first board block, a second board block, slide grooves, grooves, horizontal rods, slide wheels and slide plates, the blackboard is good in use effect, teachers' use of the blackboard is not affected by the fact that the use effect of the blackboard is not good, teaching progress delaying caused by the fact that the blackboard is inconvenient to use is avoided, and the problem that the blackboard is poor in use effect is solved.
Description
technical field [0001] The invention relates to the technical field of blackboards, in particular to a blackboard with good use effect. 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. Writing materials are written on it, mostly black, dark green, white or beige, but most of the general blackboards are not used well, and the poor use of the blackboard will affect the use of the blackboard by school teachers and bring inconvenience to the use of the teacher , It may even delay the progress of teaching. Due to the above problems, we have introduced a blackboard with good effect. Contents of the invention [0003] The object of the present invention is to provide a blackboard with good use effect, which has the advantage of good...
