Translation blackboard

Abstract

The invention provides a translation blackboard, belongs to the technical field of teaching equipment, and solves the problem of easiness in shaking of the blackboard due to excessive gap between the blackboard and a slide rail side wall in the sliding process in a traditional translation blackboard. The translation blackboard comprises a fame, and a slide rail 1 and a slide rail 2 arranged at two ends of the frame; a blackboard is arranged between the slide rail 1 and the slide rail 2; a control motor and a rack connected with the blackboard are arranged at the upper end of the blackboard; the control motor is connected with a gear engaged with the rack; the slide rail 2 is projected to form a slide plate; at least one pair of adjusting grooves formed in the thickness direction of the blackboard is respectively arranged at the upper end and the lower end of the blackboard; multiple pairs of adjusting blocks are arranged at the upper end and the lower end of the blackboard; each pair of adjusting blocks at the upper end of the blackboard can slide along the corresponding adjusting grooves, and can be butted against two side walls of the slide rail 1; and each pair of adjusting blocks at the lower end of the blackboard can slide along the corresponding adjusting grooves and can clamp the slide plate. The translation blackboard can be more stable in the use process.

Problems solved by technology

[0002] With the progress of the times, teaching instruments and equipment have also developed rapidly. Blackboards are often used by teachers in the teaching process. With the increase of knowledge and the lengthening of courses, sometimes only a blackboard is not enough for teachers to write on the blackboard. , in traditional teaching, the general teacher uses blackboard eraser to clean the blackboard and write on the blackboard again, which causes some students to fail to record the knowledge points written on the blackboard on the blackboard in time, and also wastes the teacher's teaching time

[0003] In the prior art, a plurality of matching blackboards are generally installed on the frame, so that the blackboard needs to move left and right or up and down to facilitate the teacher’s writing. Parallel slide rails are set at the upper and lower ends, and the hanging wheels or rollers can slide in the slide rails. However, during the long-term sliding process, the gap between the hanging wheels or rollers and the side walls of the slide rails is relatively large, which makes the blackboard slide left and right. At the same time, after the blackboard is translated in place, when the teacher is writing on the blackboard, due to the excessive gap between the hanging wheel or the roller and the side wall of the slide rail, noise or vibration will be generated, which will affect the quality of the teacher's writing on the blackboard
