Blackboard with book supporting structure

Abstract

Disclosed is a blackboard with a book supporting structure. The blackboard comprises a blackboard body. A transverse guide rail groove is formed in the bottom edge of the blackboard body, a movable sliding block is arranged in the transverse guide rail groove, and a bearing block is further arranged in the transverse guide rail groove. A concave hole with an opening formed in the top is formed in the bearing block, a supporting rod is arranged in the concave hole, and a book bearing plate is arranged on the top of the supporting rod. An adjusting cavity which is communicated with the concave hole is formed in the bearing block, an adjusting toothed disk is arranged in the adjusting cavity, and the center of the adjusting toothed disk is connected to the interior of the adjusting cavity through a rotating shaft. A toothed groove which is linear in the vertical direction is fixedly formed in the surface of the supporting rod, a hand cranking rod which is connected with the rotating shaft is arranged on the outer side of the bearing block, an arc-shaped convex block is fixedly arranged in the middle of the bottom surface of the book bearing plate, and an arc-shaped groove is formed in the top of the supporting rod. The blackboard with the book supporting structure is reasonable in structural setting, broad in application range, good in usage stability and high in applicability, and easy and convenient to operate, can achieve book bearing and transverse movement through the book bearing plate and the movable sliding block, and meets the utilization requirements of different teachers.
