Three-dimensional display device for electronic blackboard and using method thereof

Abstract

The invention discloses a three-dimensional display device for an electronic blackboard and a using method thereof, and relates to the technical field of electronic blackboards. The device comprises a base, a rotating shaft cylinder and mounting and fixing frames; a fixing column is rotationally connected to the axis of the upper surface of the base; a through hole is formed in the axis of the lower surface of the rotating shaft cylinder; a convex cap is arranged at the axis of the upper surface of the rotating shaft cylinder; a plurality of through grooves are uniformly formed in the peripheral side of the rotating shaft cylinder; and the mounting fixing frame is formed by sequentially connecting an upper parallel rod, a right connecting plate, a lower connecting plate and a left parallel rod end to end. The plurality of mounting and fixing frames are uniformly arranged on the rotatable shaft cylinder, the electronic blackboard is placed in the fixing frame, and a nylon adhesive tape bypasses the rollers to limit the electronic blackboard, so that the electronic blackboard is fixed and prevented from falling off in the display process, meanwhile, the electronic blackboards of different sizes can be fixed, operation is convenient, and consumers can check the electronic blackboards conveniently.

Description

technical field [0001] The invention belongs to the technical field of electronic blackboards, and in particular relates to a three-dimensional display device for electronic blackboards and a usage method thereof. Background technique [0002] Electronic blackboard is an organic combination of traditional blackboard and multimedia teaching, seamless switching, the same area not only realizes the chalk writing function of ordinary blackboard, but also provides high-definition display and interactive touch, including playing teaching courseware, videos, pictures, animations And various rich multimedia teaching functions such as annotations. The product seamlessly combines traditional blackboards with intelligent high-definition interactive display functions, and deeply integrates traditional teaching with modern technology to bring the best teaching experience. [0003] When the electronic blackboard is sold or displayed, it is fixed on the display wall by bolts for consumers...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a three-dimensional display device for an electronic blackboard and its use method. By arranging a plurality of installation and fixing frames evenly on the rotatable shaft tube, the electronic blackboard is placed in the fixed frame, and the electronic blackboard is driven by nylon adhesive. The roller fixes the electronic blackboard, which solves the problems of wasting space, time-consuming disassembly and assembly of the existing electronic blackboard exhibition
