Description
Technical field
The utility model relates to a kind of English-teaching aid, especially a kind of English teaching board.
Background technology
In English teaching, it is the basis that student learns English well that English alphabet is write, teacher is when giving lessons in classroom, need before writing first to draw equidistant four straight lines respectively with pen and ruler, so not only troublesome poeration, waste time and energy, and four straight lines are also difficult to keep equidistant, affect teaching efficiency, inconvenience is brought to teaching, although there is many scribers had about English teaching now, but all have the following disadvantages in actual use: 1, first paintbrush will be loaded onto in each pen clip when using scriber setting-out, then setting-out could be started, so not only increase the workload of teacher, but also waste a large amount of time, what 2, must ensure between paintbrush in line drawing process is neat, otherwise the four line lattice drawn are just imperfect, 3, to take time before teaching four line lattice of deflorating, to take time again after teaching terminates and grid wiped, both time-consumingly also to require great effort.
Summary of the invention
Technical assignment of the present utility model is for above the deficiencies in the prior art, and provides a kind of English teaching board.
The utility model solves the technical scheme that its technical matters adopts: a kind of English teaching board, comprise board, wherein said board is blank, described blank is cavity structure, support column is provided with in described blank side, controller is provided with in described support column, groove is provided with inside described support column, two a series of paintings line blocks are at least provided with in described groove, four laser lamps are equipped with in described every a series of paintings line block, connected by expansion link between described laser lamp, range sensor is equipped with bottom described expansion link, connected by telescopic arm between described setting-out block, control module is provided with bottom described blank, the input end of described controller is connected with described control module and range sensor, output terminal is connected with described expansion link and telescopic arm.
Described telescopic arm and expansion link are electric expansion bar.
Advantage of the present utility model: the light 1, sent by laser lamp just can replace the setting-out of chalk, such teacher just goes to load paintbrush in each pen clip without spended time again, not only alleviates the workload of teacher, and also a saving the time; 2, just can complete four whole line lattice by the light moment of laser lamp, and the complete of four line lattice can be ensured; 3, teacher only need open laser lamp when four line lattice used by needs, does not need with then being closed by laser lamp, simple to operation, but also time saving and energy saving.

Fig. 2 is the utility model support column inner structure schematic diagram.
Fig. 3 is the utility model control framework figure.
Embodiment
Below in conjunction with Figure of description, the utility model is described below.
As shown in Figures 1 to 3, a kind of English teaching board, comprise board, wherein said board is blank 1, described blank 1 is in cavity structure, support column 3 is provided with in the side of described blank 1, controller 4 is provided with in described support column 3, groove is provided with inside described support column 3, two a series of paintings line blocks are at least provided with in described groove, four laser lamps 5 are equipped with in described every a series of paintings line block, connected by expansion link 6 between described laser lamp 5, range sensor 7 is equipped with bottom described expansion link 6, connected by telescopic arm 8 between described setting-out block, control module 2 is provided with bottom described blank 1, the input end of described controller 4 is connected with described control module 2 and range sensor 7, output terminal is connected with described expansion link 6 and telescopic arm 8.
Described telescopic arm 8 and expansion link 6 are electric expansion bar.
Its principle of work is: the expansion link 6 first between laser lamp 5 and range sensor 7 are mutually corresponding, each range sensor 7 correspondence controls an expansion link 6, then teacher at school time can adjust distance in same group of laser lamp between each laser lamp 5 by control module 2, can also control often to organize the distance between laser lamp, teacher is when four line lattice used by needs, first the distance in same group of laser lamp between each laser lamp 5 is inputted by control module 2, then the data detected will be passed to controller 4 by range sensor 7, controller 4 is by contrasting with the distance value of setting, if the distance value detected is less than setpoint distance value, so controller 4 extends with regard to controlling expansion link 6, just control expansion link 6 if contrary to shorten, it is made to be consistent with the distance of setting, then laser lamp 6 is opened by control module 2, four laser lamps 5 in same like this group will all be lighted, the light of laser lamp 5 will become complete four line lattice out at the rear row of blank, whole process operation is simple and convenient.
Claims (2)
1. an English teaching board, comprise board, it is characterized in that: described board is blank, described blank is cavity structure, support column is provided with in described blank side, controller is provided with in described support column, groove is provided with inside described support column, two a series of paintings line blocks are at least provided with in described groove, four laser lamps are equipped with in described every a series of paintings line block, connected by expansion link between described laser lamp, range sensor is equipped with bottom described expansion link, connected by telescopic arm between described setting-out block, control module is provided with bottom described blank, the input end of described controller is connected with described control module and range sensor, output terminal is connected with described expansion link and telescopic arm.
