described multimedia foreign language dais, described folding rack comprises straight-bar, the top of described straight-bar connects connection-peg, described connection-peg grafting extension bar also connects by rivet, the top of described extension bar connects connection-peg, described connection-peg connects lap bars, and described lap bars connects described screen, and described screen twists in described lap bars.
described multimedia foreign language dais, the two ends of described lap bars connect oblique fulcrum bar simultaneously, between described oblique fulcrum bar, mutually peg graft, oblique fulcrum bar described after pegging graft connects clip, described clip connects telescopic cantilever bar, and described telescopic cantilever bar connects outer space bulbus cordis, and described outer space bulbus cordis inner sleeve has interior hollow ball, described interior hollow ball is connected and fixed circle, and described retainer plate is projecting apparatus fixedly.
described multimedia foreign language dais, described combination box comprises base plate, overhead door after described base plate is connected through the hinge, described base plate connects front apron, right baffle-plate and right baffle plate simultaneously, described right baffle-plate and described right baffle plate are all by described chain connection half overhead door, described front apron is connected described straight-bar with the junction of described right baffle-plate, described front apron is connected described straight-bar with the junction of described right baffle plate, described base plate connects supporting leg, and described supporting leg connects movable pulley.
beneficial effect:
1. volume of the present utility model is small and exquisite, and Foreign Language Teacher can shift any classroom onto at school time and explain use, and small investment is applicable to small city and rural area very much, also has school from far-off regions to use.
after paying combination box when folding rack of the present utility model is used, launch screen again, facilitate projection not play while not using and fold in combination box, do not take up room, deposit conveniently, the screen after raising is convenient to student viewing.
the utility model can raise notebook computer as required, is convenient to improve drop shadow effect, is convenient to student viewing, improves Quality of Foreign Language Teaching.
compact mechanical structure of the present utility model, the about space of the trifle that takes up room, lifting is effective, safe, practical, is easy to carry.
