Be undoubtedly Western languages not with English is immediate, this language still uses now in the northern Friesland of Holland, nearly 500,000 users.Some think that low ground Scotch is an independent language close with English, and some then think that it is a dialect of English.The low ground Saxon of Scotch, eastern Netherlands and Spruce from Northern Germany and English are also very close.Other relevant language comprise Dutch, Afrikaans and German.The Normans belonged under Germanic branc conquers England in 11st century, brings a large amount of French vocabulary, has enriched outside English glossary largely, relatively also orders about much primary Germany's vocabulary and cancels.
Existing English teaching board needs manually to carry out rotating or Non-follow control in use, and it uses inconvenience, complicated operation, inefficiency.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of high-level efficiency English teaching board.
A kind of high-level efficiency English teaching board of the present utility model, it comprises framework, display screen, guidance panel, explanation plate, rotating shaft, drive motor, base, controller, reversing switch, baffle plate, timing relay, the left side of framework is provided with display screen, the lower end of display screen is provided with guidance panel, explanation plate is arranged on the right side of framework, the bottom of framework is provided with rotating shaft, rotating shaft is connected with the axle of drive motor, drive motor is arranged on the inside of base, controller and timing relay are installed in the inside of base, two reversing switches are arranged on the rear side at base two ends respectively, the front end of base of frame both sides is all provided with baffle plate, baffle plate matches with the contact of reversing switch, two reversing switches are by the input end of timing relay and controller, the output terminal of controller is connected with drive motor.
As preferably, the bottom of described base is provided with slipmat.
As preferably, described timing relay is electronic type timing relay.
The beneficial effects of the utility model are: be convenient to realize timing reversing, easy and simple to handle, easy to use, and increase work efficiency, structure is simple.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure: 1-framework; 2-display screen; 3-guidance panel; 4-explains plate; 5-rotating shaft; 6-drive motor; 7-base; 8-controller; 9-reversing switch; 10-baffle plate; J1-timing relay.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises framework 1, display screen 2, guidance panel 3, explanation plate 4, rotating shaft 5, drive motor 6, base 7, controller 8, reversing switch 9, baffle plate 10, timing relay J1, the left side of framework 1 is provided with display screen 2, the lower end of display screen 2 is provided with guidance panel 3, explanation plate 4 is arranged on the right side of framework 1, the bottom of framework 1 is provided with rotating shaft 5, rotating shaft 5 is connected with the axle of drive motor 6, drive motor 6 is arranged on the inside of base 7, controller 8 and timing relay J1 are installed in the inside of base 7, two reversing switches 9 are arranged on the rear side at base 7 two ends respectively, the front end of framework 1 two bottom sides is all provided with baffle plate 10, baffle plate 10 matches with the contact of reversing switch 9, two reversing switches 9 pass through the input end of timing relay J1 and controller 8, the output terminal of controller 8 is connected with drive motor 6.
Further, the bottom of described base 7 is provided with slipmat.
Further, described timing relay J1 is electronic type timing relay.
The principle of work of this embodiment is: adopt drive motor 6 to drive framework 1 to rotate, when framework 1 rotates, baffle plate 10 can touch reversing switch 9, reversing switch 9 realizes time delay commutation by timing relay J1, easy to use, easy and simple to handle, precise control, adopt the display screen display content of courses, save the time, work efficiency is high simultaneously.
