Abstract
The utility model is related to a kind of blackboard for English teaching, including blackboard body, ground glass plate, fibre bundle, controller, shift knob and brightness regulation knob, blackboard body upside sets ground glass plate, fibre bundle is uniformly arranged between blackboard body and ground glass plate, and fibre bundle includes four identical optical fiber, and every optical fiber is parallel is equally spaced, blackboard body side sets controller, fibre bundle is connected with the fibre-optical splice set in controller, and shift knob and brightness regulation knob are respectively provided with controller.The utility model beneficial effect：Easy to use, solving tradition and drawing the method for four line lattice not only wastes time and energy, and spacing between four line ruling bars is not uniform enough, and not straight enough the problem of lines, and long service life is more environmentally-friendly.
Description
Technical field
The utility model is related to a kind of blackboard for teaching, more particularly to a kind of blackboard for English teaching.
Background technology
Teacher is needed to be written on regular English word on blackboard in English teaching at present, and this is accomplished by blackboard
The upper four line lattice for drawing specification, the method that tradition draws four line lattice is mostly the direct Freehandhand-drawing on blackboard, is not only wasted time and energy, and
And four spacing between line ruling bar is not uniform enough, and lines are not straight enough, influence writing quality.
Utility model content
Technical problem to be solved in the utility model is：A kind of English teaching aid is provided, is solved tradition and is drawn four
The method of line lattice not only wastes time and energy, and spacing between four line ruling bars is not uniform enough, and not straight enough the problem of lines.
The utility model is by solving the problems, such as the technical scheme for using set forth above：
A kind of blackboard for English teaching, including blackboard body 1, ground glass plate 2, fibre bundle 3, controller 4, shift knob
5 and brightness regulation knob 6, the upside of blackboard body 1 sets ground glass plate 2, uniform between blackboard body 1 and ground glass plate 2
Fibre bundle 3 is set, and fibre bundle 3 includes four identical optical fiber 7, and every optical fiber 7 is parallel is equally spaced, blackboard body 1
Side sets the fibre-optical splice set in controller 4, fibre bundle 3 and controller 4 and is connected, be respectively provided with controller 4 switch by
Button 5 and brightness regulation knob 6.
The opposite side of described blackboard body 1 sets magazine 8, is easy to place blackboard eraser and chalk holder.
Described ground glass plate 2 is black ground glass plate, and the color contrast with white chalk is high.
Spacing between described adjacent fibre bundle 3 is easy to distinguish the often line lattice of row four more than the every spacing of optical fiber 7.
Described optical fiber 7 is the optical fiber for emitting white light, with preferable visual effect.
Operation principle of the present utility model：Optical fiber has good light transmission capability, but due to manufacture processing,
The optical fiber for being produced inevitably produces light scattering phenomenon, so as to be detected by human vision, so the utility model
The light scattering phenomenon for just having used optical fiber to produce, it is achieved thereby that need not draw four line lattice in English teaching, only need to make light
The fine Shu Faguang and refraction action by ground glass plate sees the clearly line lattice of light four.
The beneficial effects of the utility model are：1st, it is easy to use, solve traditional method for drawing four line lattice not only expense
When it is laborious, and spacing between four line ruling bars is not uniform enough, and not straight enough the problem of lines, long service life, more
Environmental protection.2nd, the opposite side of blackboard body sets magazine, is easy to place blackboard eraser and chalk holder.3rd, ground glass plate is black mill
Sand glass plate, the color contrast with white chalk is high.4th, the spacing between adjacent fibre bundle is more than the every spacing of optical fiber,
It is easy to distinguish the often line lattice of row four.5th, optical fiber is the optical fiber for emitting white light, with preferable visual effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- blackboard bodies, 2- ground glass plate, 3- fibre bundles, 4- controllers, 5- shift knobs, 6- brightness regulations
Knob, 7- optical fiber, 8- magazines.
Specific embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
Reference picture 1, a kind of blackboard for English teaching described in this specific embodiment, including blackboard body 1, ground glass
Plate 2, fibre bundle 3, controller 4, shift knob 5 and brightness regulation knob 6, the upside of blackboard body 1 set ground glass plate 2, black
Fibre bundle 3 is uniformly arranged between plate body 1 and ground glass plate 2, and fibre bundle 3 includes four identical optical fiber 7, and every light
Fibre 7 is parallel to be equally spaced, and the side of blackboard body 1 sets controller 4, the fibre-optical splice company for setting interior with controller 4 of fibre bundle 3
Connect, shift knob 5 and brightness regulation knob 6 are respectively provided with controller 4.
The opposite side of described blackboard body 1 sets magazine 8, is easy to place blackboard eraser and chalk holder.
Described ground glass plate 2 is black ground glass plate, and the color contrast with white chalk is high.
Spacing between described adjacent fibre bundle 3 is easy to distinguish the often line lattice of row four more than the every spacing of optical fiber 7.
Described optical fiber 7 is the optical fiber for emitting white light, with preferable visual effect.
The operation principle of this specific embodiment：Optical fiber has good light transmission capability, but due to manufacture processing
Reason, the optical fiber for being produced inevitably produces light scattering phenomenon, so as to be detected by human vision, so this practicality
The new proper light scattering phenomenon for having used optical fiber to produce, it is achieved thereby that need not draw four line lattice in English teaching, only needs
Make fibre bundle luminous and the refraction action by ground glass plate sees the clearly line lattice of light four.
The beneficial effect of this specific embodiment is：1st, it is easy to use, solve the method for tradition four line lattice of drafting not
Only waste time and energy, and spacing between four line ruling bars is not uniform enough, and not straight enough the problem of lines, long service life,
It is more environmentally-friendly.2nd, the opposite side of blackboard body sets magazine, is easy to place blackboard eraser and chalk holder.3rd, ground glass plate is black
Color ground glass plate, the color contrast with white chalk is high.4th, the spacing between adjacent fibre bundle is more than every optical fiber
Spacing, is easy to distinguish the often line lattice of row four.5th, optical fiber is the optical fiber for emitting white light, with preferable visual effect.
Specific embodiment of the utility model is not constituted to limitation of the present utility model, every to use phase of the present utility model
Like structure and change, in protection domain of the present utility model.
