Abstract

The invention discloses a novel blackboard. The novel blackboard comprises a main body and a machine body, the main body is connected with a connecting ring through a fixing sheet, and a hook is arranged above the connecting ring; a rolling bearing is inlaid in the upper part of the hook, and a cross rod is installed inside the rolling bearing; a movable rod is installed above the cross rod, and two ends of the movable rod are connected with first pulley blocks; the two ends of the cross rod are provided with bearing caps, the outside of each first pulley block is provided with a first fixingrailway, and the upper surface of each first fixing railway is provided with a fixing hole in a penetrating mode; and the middle of the cross rod is connected with the machine body through the rollingbearing, the two sides of the machine body are provided with second pulley blocks, and the outside of each second pulley block is provided with a second fixing railway. According to the novel blackboard, the machine body and the second pulley blocks are arranged, a motor is arranged in the machine body, so that the motor drives the second pulley blocks, then the second pulley blocks can move forwards and backwards, the maneuverability of the device is improved, and therefore the machine body can move back and forth.

Description

technical field [0001] The invention relates to the field of education technology, in particular to a novel blackboard. Background technique [0002] The blackboard is used for teachers to write educational content on it and write questions that need to be explained to students. Its role is very important. However, students in the back row cannot see the words on the blackboard clearly during use. Students need to keep asking questions. The words on the blackboard can be known, thereby causing the problem of poor learning efficiency. [0003] Therefore, we have proposed a new type of educational blackboard to solve the above-mentioned problem that students cannot see the blackboard in class and have poor learning efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a new type of educational blackboard to solve the problem that the students in the back row cannot see the words on the blackboard in class in the current market rai...
