Description
Technical field
The utility model relates to a kind of real object exhibition booth, particularly relates to a kind of multimedia teaching multi-angle real object exhibition booth.
Background technology
Along with the development of science and technology, daily teaching has been come in multimedia teaching, real object exhibition booth is exactly wherein one, can a less thing be projected on giant-screen by its conversion in teaching, student is allowed to see more clearly, for teaching is provided convenience, no longer be crowded together with everybody and surround and watch, improve efficiency of teaching, but present real object exhibition booth is all take from above, exhibition booth is made up of opaque entity and keeps flat on the table, operation is all easy to for displaying plane object, can only an angle place when running into some, turn over and be not easy to put steady object, want multi-angled shooting just to show dying, so this deficiency still needs to be improved.
Utility model content
In order to the utility model that solves the problem provides a kind of multimedia teaching multi-angle real object exhibition booth.
The technical solution adopted in the utility model is: a kind of multimedia teaching multi-angle real object exhibition booth, comprise camera, support arm and exhibition booth, it is characterized in that exhibition booth is made up of transparent table top and frame, support arm is made up of forearm and upper arm, forearm front end connects camera by pipe-menders and forms wrist joint, the hinged formation elbow joint in forearm rear end and upper arm front end, upper arm rear end is hinged on frame, frame is hinged with three with upper supporting leg, the hinged termination of supporting leg is outward extended with and supporting leg, limited block that jointed shaft is vertical, and there is a blank on transparent table top upper berth.
Further, described forearm is made up of two sections of hinge bars, and upper arm is connected and composed by two sections of expansion links.
Further, described each hinge point in relative rotation two parts is respectively equipped with graduated collar and tuning drive gear.
Exhibition booth is set to transparent by the utility model, run into can only angle place turn over put unstable object time, need lower view, only supporting leg need be erected, camera is translated into below exhibition booth, take away blank, just can obtain steady and audible image, supporting leg can be turned up when not needing bottom to make a video recording, exhibition booth keep flat take up room little.
