Abstract
The utility model discloses a multimedia teaching projection curtain wall. The multimedia teaching projection curtain wall comprises a rolling curtain motor, a flexible curtain wall, and a support, wherein the flexible curtain wall is a composite curtain wall which is formed by fixing a plurality of hinged transverse curtain sheets at the rear side of an integral curtain. The multimedia teaching projection curtain wall takes the integral curtain of the composite curtain wall as a carrier for projection and writing, and takes the composite curtain sheets as a support, so that projection and writing are combined to facilitate quick and direct expression of a teaching purpose of the teacher. The curtain sheets are good in rolling effect, and has a certain hardness, thus can be fixed with an automation compressing mechanism. The multimedia teaching projection curtain wall is simple in structure, good in usage effect, easy to process and modify, and very suitable for popularization and execution.
Description
Technical field
The utility model relates to multimedia teaching technical field of tools, is specifically related to a kind of multimedia teaching projection curtain wall.
Background technology
At present, be that school, R&D institution, enterprise or government unit all use multimedia overhead projector technology more and more.Existing multimedia overhead projector instrument can be expressed course content in quicklook ground, and scene explanation and the content of preparing lessons are combined closely, and saves on-the-spot setup time, reaches good teaching efficiency.But existing multimedia curtain wall mostly adopts flexible screen-rollong form, can only be used for show and can not be used for writing.Need the interim process of supplementing or carrying out deep demonstration according to the interactive situation of student owing to having unavoidably in classroom displaying process, and the multimedia tool of existing flexible screen-rollong form does not have the on-the-spot display function that supplements, again supplement presentation process in order to reach scene, conventionally need to place again a blackboard or whiteboard bracket on multimedia curtain wall side for write use temporarily.The blackboard of newly establishing or blank can not with the direct combination of curtain wall, so the content that can not express is directly illustrated on multimedia curtain wall, affect quality of instruction.
Utility model content
The purpose of this utility model is problem and the defect existing for existing multimedia teaching instrument, and a kind of multimedia teaching projection curtain wall is provided.
For achieving the above object, adopt following technical scheme: a kind of multimedia teaching projection curtain wall, comprise rolling motor, flexible curtain wall and support, described flexible curtain wall is to be fixed with the composite curtain wall that multiple hinged horizontal curtain sheets form at monoblock type curtain rear, is provided with automatic compaction mechanism in described composite curtain wall lower limit simultaneously.
Between adjacent horizontal curtain sheet, be respectively arranged with upper shaft hole and lower shaft hole, upper and lower axis hole is inlaid in together and is provided with same rotating shaft mutually.
Described automatic compaction mechanism comprises that at least one is fixed on the base on body of wall, on base, by the hinged briquetting of bearing pin, is provided with arc groove in the inner side of briquetting, is provided with and can makes the inwardly torsion spring of motion of briquetting between described briquetting and base; Below composite curtain wall, be provided with arc fin, this arc fin mates and snaps together with described arc groove simultaneously.
Described support comprises the holder at roller shutter urceolus and two ends, and the holder at two ends is arranged on body of wall, and the two ends of rolling motor are arranged on holder madial wall, and roller shutter urceolus is arranged on holder.
Beneficial effect: flexible curtain wall is modified into composite curtain wall by the utility model, the monoblock type curtain that utilizes composite curtain wall is as projection and the carrier write, using the curtain sheet of combination as support, combine thereby can and write projection, be convenient to quicklook and express teacher's teaching intention.Curtain sheet can not only support monoblock type curtain, and rolled efficiency is better.By automatic compaction mechanism, whole composite curtain wall can be compressed and is fitted on body of wall, prevent that it from swinging arbitrarily.Composite curtain wall is launch or curlingly all have a certain degree of hardness, and its end can provide enough support strengths and enter in the groove of automatic compaction mechanism.The utility model is simple and reasonable, and result of use is good, and easily process and remould is applicable to promotion and implementation very much.
