Abstract

The utility model discloses a multifunctional rolling type automatic blackboard which comprises a frame, a rolling curtain mechanism, a wiping mechanism and a lining mechanism. The multifunctional rolling type automatic blackboard can turn an annular blackboard surface left and right by means of the driving of an electromotor, thereby being convenient for students to read and memorize; the annular board surface can be returned to repeatedly watch if the students can not memorize; and the blackboard surface also can be taken as a screen of a projecting apparatus. With the driving mode of the electromotor, the blackboard can lead a strip-shaped wiper to swing and rub back and forth to delete the original content; with a white board pen, the blackboard is dust-resistant, can clean the environment, is beneficial to health, can automatically erase handwriting, and is time-saving, labor-saving and safe; when in the practical use, the area of the blackboard surface is twice as large as that of a visible area, so that the blackboard has a long continuous writing time and does not need to be frequently erased; and the blackboard has the functions of memorizing, music playing and time displaying, and can draw up a straight line and a circle with a lining ruler.

Description

The multi-functional rolling type automatic blackboard

Technical field

The utility model relates to a kind of teaching aid, particularly a kind of multi-functional rolling type automatic blackboard with line drawing ruler.

Background technology

The blackboard of existing teaching usefulness is wooden or the blackboard made of materials such as frosted glass or iron porcelain, on blackboard, write or draw with chalk, because dust from flying contaminated environment, long-term contact chalk dust can produce harmful effect to teachers and students' health, and the easy counter tide of chalk, chalk behind the counter tide is difficult on the blackboard and writes, writing is unclear, word and to erase the board with blackboard eraser all be the thing of part effort writes with chalk, and the pupil is because of can't reach blackboard, often stepping on the writing of stool on erasing the board, and easily causes tumble injury, very dangerous, erase the board for short person's people and bring difficulty.And, it is comparatively limited that blackboard is write literal, in order to enlarge the writing surface area, someone proposes comparatively advanced two boards arranged superposed and moves up and down, the method that is used alternatingly has increased than traditional blackboard and to have write literal, but can not change the blackboard aspect at any time according to instructor's needs, the labour intensity that erases the board is big, operates not too flexible etc.In addition, line tool commonly used mostly adopts common meter ruler, set square etc. on blackboard at present, because volume is bigger, the position instability, the normal chi body that takes place tilts, moves in the setting-out process, influence the setting-out effect, and the common drawing instrument of the singlehanded grasp of user is comparatively painstaking, also easily comes off and causes damage.These looks for a change, the design people has proposed a kind of simple in structure by practical studies repeatedly, low price is write literal 2 times than traditional blackboard area, can increase on demand at any time and write literal, memory function is arranged, and the multi-functional rolling type automatic blackboard of band line drawing ruler.

Summary of the invention

The purpose of this utility model provides a kind of multi-functional rolling type automatic blackboard, and it can increase at any time on demand writes literal, and memory function is arranged, the multi-functional rolling type automatic blackboard of band line drawing ruler.

For addressing the above problem, the technical solution of the utility model is: a kind of multi-functional rolling type automatic blackboard, comprise framework, rolling curtain mechanism, Wiping mechanism, setting-out mechanism, framework is the rectangular framework that light weight angle steel or corrosion resistant plate are made, electronic player is equipped with in its underpart, electronic watch, gauge tap, pen container is being fixed on its right, electronic player is the ready-made player that carries loudspeaker, two kinds of flash disk interfaces and power switch are arranged on the electronic player, the input electricity of player is directly received on the battery main switch, opens the player switch when last music lesson or other need the audio frequency course and flash disk is injected directly to pay attention to the class on the flash disk interface gets final product; Electronic watch is the ready-made clock and watch that show date and time, and the input electricity of electronic watch is directly received on the battery main switch, and teachers and students give birth to by time course and grasp teaching and study schedule.Gauge tap comprises battery main switch, curtain switch and wiping switch, battery main switch is the switch that extraneous 220V electricity is provided to the blackboard consumer, the curtain switch is a pole changer, the curtain switch is connected with the curtain motor with battery main switch by electric wire, by pinning curtain switch two respectively curtain can positive and negatively be rotated, writing full curtain face simultaneously is to forward the blackboard back side by the curtain switch to by it to store, treat that two class go back to storage when after class needing to look back soon a curtain face briefly explains, if or the student does not write down, also can go back to heavily and see; The wiping switch also is a pole changer, the wiping switch is connected with the wiping motor with battery main switch by electric wire, wiping switch and wiping motor are just, two the normally closed buttons of contacting respectively on the circuit for reversing, pinning wiping switch left end makes motor just change the felt rug plate to compress an act face, the rocking bar of felt rug plate is pushed normally closed button and is made the motor outage simultaneously, the felt rug plate is in the state that compresses act face, this moment, curtain rotated the writing on the erasable curtain face, pinning wiping switch right-hand member makes motor counter-rotating felt rug plate leave an act face, the rocking bar of felt rug plate is pushed normally closed button and is made the motor outage simultaneously, the felt rug plate is in the state of branch opening face, and this moment, curtain rotated not the writing on can wiping curtain face; Four or more pen containers weld sideling or stick on the frame right, can put into versicolor blank pen, and the teacher selects use as required.

Rolling curtain mechanism comprises curtain, left and right sides cylinder, decelerator, the curtain motor, curtain is to piece together with rubber strip or plastic tape or metal strip annular to make, curtain is looped around on two parallel cylinders, regulating between the cylinder apart from the available adjustment bolt, the liner plate that is fixed in framework is close on curtain writing surface north, this liner plate remain on when writing on the curtain not can swing or a curtain face fall in and be unfavorable for writing, left and right sides cylinder by bearing fixing on framework, right cylinder connects with decelerator by shaft coupling, decelerator connects with the curtain motor by shaft coupling, decelerator and curtain motor all are fixed on the framework, roll left the tube bearing withstand the adjusting screw mandrel up and down, screw mandrel is fixed on the framework by support bar, the bolt of screwing on the screw mandrel, and bolt promotes the screw mandrel adjustable range by support bar.
