Rotation type multi-layer display rack for teaching

Abstract

The invention discloses a rotation type multi-layer display rack for teaching. The rotation type multi-layer display rack for teaching comprises a base, a regulating motor, a lifting column and a fixing frame, wherein the regulating motor is fixedly mounted at the top end of the base, the lifting column is mounted at the output end of the regulating motor, a lifting rod at the top end of the lifting column penetrates through the center of the fixing frame, a locking block is mounted at the joint of the lifting rod and the fixing frame, a support rod is hinged between a support plate on the lifting rod and a hinge base at the lower end of the fixing frame, and a first layer of display board and a second layer of display board are mounted between slide rails at the top end and the bottom endinside the fixing frame in a sliding manner. The rotation rack provided by the invention is simple in structure, is convenient to use, and is rapid and effective, through the motor and the lifting column, the rotation operation and lifting operation of the display rack are realized, and thus writing for teaching is facilitated; through the arrangement of the two layers of display boards, the blackboard-writing area for teaching is greatly increased, and thus the teaching efficiency and teaching quality of teachers are improved.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a rotating multi-layer teaching display stand.
