Abstract

The invention belongs to the technical field of teaching appliances, in particular to an orbit transferring type push-pull blackboard. The orbit transferring type push-pull blackboard comprises a first aluminum sliding rail and a second aluminum sliding rail, and is characterized in that the first aluminum sliding rail and the second aluminum sliding rail are internally provided with a first sliding rail and a first arc-shaped guide groove, and a second sliding rail and a second arc-shaped guide groove; the right end of the first sliding rail is fixedly connected with the first arc-shaped guide groove; and the right end of the second sliding rail is fixedly connected with the second arc-shaped guide groove. According to the orbit transferring type push-pull blackboard, a movable blackboardcan be moved left and right according to the using requirement of teaching staff by arranging the devices, such as the first sliding rail, the second sliding rail, the arc-shaped guide grooves, the sliding assembly and the like; a first movable blackboard and a second movable blackboard are withdrawn into the first arc-shaped guide groove and the second arc-shaped guide groove by arranging a return spring when multimedia equipment is not used; and the using effect of the blackboard is better by mutual cooperation of various structures.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, and in particular relates to a track-changing push-pull blackboard.
