Description
Technical field
The utility model relates to English-teaching aid field, especially a kind of English teaching panel.
Background technology
Blackboard, as a kind of surface plate that can repeated writing, is used for teaching.Blackboard surface adopts wear-resisting and lacklustre material, can write in the above with chalk.Existing blackboard stock size height should not be less than 1000mm, width: primary school should not be less than for 3600mm, and middle school should not be less than 4000mm, edge and the vertical range of saying table top under blackboard: primary school is preferably 800-900mm; Middle school is preferably 1000-1100mm, and the horizontal range at two ends, dais and blackboard edge should not be less than 200mm, and width should not be less than 650mm, is highly preferably 200mm.Because blackboard size is larger, in use, font often can not ensure to meet normalized written, especially for english font.Write the position that the normalized written of English word should should account for according to the alphabetical order of strokes observed in calligraphy and letter in three lattice, and each letter should slightly be tilted to the right, and it is consistent that gradient is wanted.Such normalized written keeps than being easier in the books with four line three lattice.But in process of English teaching, teacher often need to write a large amount of English words, statement on blackboard, and because blackboard size is larger, teacher is difficult to ensure to meet normalized written in writing on the blackboard process.For the students of the junior years, if teacher demonstrates to student with the writing on the blackboard that does not meet normalized written for a long time, be easy to student to cause harmful effect.At present, a lot of teachers are lack of standardization for fear of writing on the blackboard, can only carry out manual line to blackboard with board foot, but manual line can take a large amount of instructional blocks of times of teacher, uses very inconvenient.
Summary of the invention
The utility model will solve the nonstandard problem of writing on the blackboard in existing English teaching, provide a kind of can system for automatic marker making, and simple in structure, cost is low, the economic environment-friendly type teaching panel of easy popularization.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of English teaching panel, comprise panel body, laser instrument, transmission device, controller and gauge tap, one side of described panel body is provided with described laser instrument, transmission device, controller and gauge tap, described laser instrument can move up and down along described panel body by described transmission device, described controller respectively with described laser instrument, described transmission device, described gauge tap electrical connection, described transmission device comprises turn-screw, nut, nut fixing device and slide unit, described nut coordinates socket with described turn-screw, and described nut is fixed on described slide unit by described nut fixing device, described slide unit can move up and down along described panel body, described laser instrument is positioned at described slide unit one side.
Further, one end of described drive lead screw connects reduction gear box, and the other end is connected with described panel body by bearing holder (housing, cover), and described reduction gear box connects stepless speed-change motor.
Further, be also provided with power supply, described power supply is connected with described controller, described laser instrument, described gauge tap and described stepless speed-change motor.
Advantage and the good effect that the utlity model has are: a kind of English teaching panel, and can realize system for automatic marker making by laser instrument is set, and realize the automatic walking of laser instrument by transmission device, overcome the problem that needs to adopt multiple laser instruments.The utility model is simple in structure, cost is low, be easy to popularization, gauge tap provides control signal for stepless speed-change motor, controller is adjusted writing on the blackboard line space a running time of stepless speed-change motor by setting, can in writing process, form a horizontal line, auxiliary teacher's normalized written font, alleviate teacher's work load, saved hours of instruction.

Detailed description of the invention
As shown in Figure 1, a kind of English teaching panel, comprise panel body 1, laser instrument 2, transmission device, controller 3 and gauge tap 4, one side of described panel body 1 is provided with described laser instrument 2, transmission device, controller 3 and gauge tap 4, described laser instrument 2 can move up and down along described panel body 1 by described transmission device, described controller 3 respectively with described laser instrument 2, described transmission device, described gauge tap 4 is electrically connected, described transmission device comprises turn-screw 5, nut 6, nut fixing device 7 and slide unit 8, described nut 6 coordinates socket with described turn-screw 5, and described nut 6 is fixed on described slide unit 8 by described nut fixing device 7, described slide unit 8 can move up and down along described panel body 1, described laser instrument 2 is positioned at described slide unit 8 one sides.
One end of described drive lead screw 5 connects reduction gear box 9, and described reduction gear box 9 connects stepless speed-change motor 10, and the other end is connected with described panel body 1 by bearing holder (housing, cover).
Also be provided with power supply, described power supply is connected with described controller 3, described laser instrument 2, described gauge tap 4 and described stepless speed-change motor 10.
Described nut 6 is socketed with described turn-screw 5, and described nut 6 is fixed on described slide unit 8 by described nut fixing device 7, one side of described slide unit 8 connects described laser instrument 2, and therefore described laser instrument 2 can move up and down along described panel body 1 along with slide unit 8.The rotational power of described turn-screw 5 derives from described reduction gear box 9, and the power resources of described reduction gear box 9 are in described stepless speed-change motor 10.Described stepless speed-change motor 10 is connected with described controller 3 again, therefore can set the rotation number of turns under 10 control signals of described stepless speed-change motor by described controller 3, can set the distance that described laser instrument 2 is once walked, i.e. the line space of writing on the blackboard.The control signal of described stepless speed-change motor 10 derives from described controller 3, and the control signal of described controller 3 derives from described gauge tap 4.After teacher writes a line word, press described gauge tap 4, described gauge tap 4 is sent to described controller 3 by relay by pulse signal.Control signal is transferred to described stepless speed-change motor 10 by described controller 3, controls electric machine rotation.When described stepless speed-change motor 10 has rotated after the setting number of turns, automatically stop operating, after running to respective distance, described laser instrument 2 stops, and the light beam that now teacher can send according to described laser instrument 2 has assisted writing on the blackboard to write.The utility model is simple in structure, cost is low, be easy to popularization, gauge tap provides control signal for stepless speed-change motor, controller is adjusted writing on the blackboard line space a running time of stepless speed-change motor by setting, can in writing process, form a horizontal line, auxiliary teacher's normalized written font, alleviate teacher's work load, saved hours of instruction.
