Description
Technical field
This utility model relates to a kind of educational aid, specifically discloses a kind of teaching board.
Background technology
Board is requisite educational aid in teaching.Blackboard is board form in early days, but owing to needing to write with chalk when using blackboard, and when chalk is write, easily there are the problems such as ash, pole affects environment.Therefore, chalk and blackboard are gradually replaced by free ink pen and blank.
Along with electronization equipment is increasingly widely used in teaching, teacher at school time be gradually rarely employed free ink pen and blank, but good PPT courseware is explained to use careful preparation.So can save the time that teacher writes on blank, be effectively increased efficiency of attending class.But, because present electronic equipment be not also impossible on the centre position at dais so that some classmates being sitting in corner can not clearly see, because of light problem, the content write on PPT clearly, makes the quality of attending class of these classmates be severely impacted.And, the curtain either projected still shows that the size of the screen of PPT is all fixing, and the content on PPT likely makes classmate below to see because of the least, brings impact also to the quality of attending class of these classmates.Additionally, because simply using PPT to explain on an electronic device, teacher cannot carry out hook for the content on PPT and draw emphasis explanation, the content that some classmates can be made cannot accurately to find teacher to explain in a PPT, makes troubles to teaching.
Utility model content
This utility model is intended to provide a kind of and can throw in PPT and can carry out the teaching board write.
Teaching board in this programme, including the base plate that can fold, the centre position of described base plate is provided with telescopic first expansion link, the front end that described base plate can be folded be provided with the first expansion link just to the second expansion link；The top of described first expansion link connects has horizontally disposed reel, described reel include discerptible upper cover, lower cover and are connected to the flexible board between cover and lower cover；It is equipped with the spool for wound flexible plate in described upper cover and lower cover, is hinged with in described lower cover for supporting upper cover and the bracing frame of lower cover；The top of described second expansion link connects mounting box, is placed with projector in described mounting box；The bottom surface of described base plate is provided with castor.
Operation principle:
During work, the first expansion link and the second expansion link are gradually stretched to certain altitude from base plate, open reel, pull up cover, make the flexible board between cover and lower cover be elongated.Bracing frame in lower cover can be erected when distance between upper cover and lower cover meets the use of flexible board, make bracing frame upper cover and lower cover be supported, and keep upper distance between cover and lower cover.Regulating the second expansion link makes the mounting box on the second expansion link top just to flexible board, the projector in mounting box is facilitated to throw on flexible board by PPT content, teacher can carry out hook for PPT content on flexible board and draws, point-to-point imparts knowledge to students simultaneously, is effectively increased teaching targets.Because there being castor on base plate, make teaching board can move to Anywhere, it is to avoid because position causes the problem that some classmates can't see partially.
When teaching board does not works, bracing frame can be gone back to horizontal direction and take in lower cover, flexible board is wound into cylinder and builds with cover and lower cover.First expansion link and the second expansion link are adjusted to short status, folded chassis, the front-end and back-end that can make base plate are upturned, and reel, mounting box, the first expansion link, the second expansion link are all wrapped in the U-shaped ring of encirclement that base plate is formed, teaching board is made to be retracted to minimum, it is simple to place and carry.
Optimizing further, described first expansion link and the second expansion link all include multiple threaded pipe, and described pipe is equipped with female thread and external screw thread, and pipe above can screw in following pipe successively from top to bottom, and the pipe of lowermost end can screw in base plate.Facilitate the first expansion link and the elongation of the second expansion link and shortening, facilitate utilization and the folding shrinking of teaching board.
Optimizing further, described flexible board is the iron plate that appearance scribbles lacquer painting.The characteristic having according to iron plate itself, enables flexible board to bend winding and to have certain flintiness conveniently to write after deployment.Lacquer painting is coated on the surface of iron plate, facilitates use water to write pen and writes, facilitates projector simultaneously.
Optimize further, the front-end and back-end that described base plate is folded are correspondingly provided with hand-held hole respectively, inside described hand-held hole, scribble rubber layer.Can be mentioned folding the teaching board drawn in by hand-held hole, utilize the elasticity of rubber, enable people to reduce the pressure that staff is experienced when mentioning teaching board by hand-held hole, conveniently guide and support.
Optimizing further, described spool is provided with the rectangular channel for clamping flexible board, and the two ends of described rectangular channel are respectively equipped with the snap close for locking rectangular channel.Open snap close, flexible board can be taken out from rectangular channel, convenient change various sizes of flexible board according to needing of teaching.
Optimize further, be provided with buckling groove in described lower cover, be provided with water in buckling groove and write pen and blackboard eraser.The water conveniently write is write pen and is placed in reel together with blackboard eraser.
Optimizing further, described castor is universal wheel.Conveniently can move board in all directions on ground when teaching of use board.
Optimizing further, described mounting box just one side to flexible board has the opening for projector projects, and the surrounding of described opening is hinged with can be with the baffle plate of mounting box snapping.Conveniently projector is firmly placed in mounting box, convenient by projector taking-up when opening baffle plate.
Optimization, support frame as described above at least two, and the bottom of two bracing frames are symmetricly set in lower cover along the perpendicular bisector of the length direction of lower cover further.Facilitate two bracing frames that stress balance between cover and lower cover when vertically supporting cover and lower cover, can be made.
Optimizing further, described first expansion link and the second expansion link are connected to the center of reel and mounting box.Reel and mounting box is made to be in balanced steady state by the first expansion link and the second expansion link when supporting.
