Description
Technical field
The utility model relates to a kind of four line lattice demonstration tools, belong to English study technical field.
Background technique
Common format in four line format English teachings, for king's English letter and word written form, English letter
And usually to write on four lines various for word, English teacher give lessons write writing on the blackboard on blackboard or blank when in order to neatly drawing
One, also four line lattice are drawn on plate giving lessons, signature pen or chalk can only be relied on along straight however, teacher draws four line lattice on blank
The picture of ruler one line, one line, wastes time and efficiency very much.
Utility model content
Against the above technical problems, the utility model aim is to provide a kind of four line lattice demonstration tools, when English teaching
Without being drawn with pen to four line lattice, directly four line lattice are shown, improve efficiency of giving lessons.
Four lines lattice demonstration tool described in the utility model, including rectangular base plate and rectangular glass, floor length are greater than
Glass plate length, bottom plate is equal with width of glass sheet, plate upper surface two sides edge and glass sheet lower surface two sides edge
It is fixedly connected respectively by the first support bar of bar shaped with second support bar, forms bar shaped cavity between bottom plate and glass plate, it is empty
Intracavitary to be equipped with 4 elastic webbings, 4 elastic webbing both ends are pierced by after cavity equidistantly to be fixed with the first fixed plate, the second fixed plate respectively,
Backplate surface on the outside of glass board ends is respectively equipped with several the first fixation holes being equally spaced, the second fixation hole, and first is solid
Determine hole, the second fixation hole into column distribution, the first fixed plate, the second fixed plate lower surface are respectively equipped with the first plug, second insert
Head, the first plug, the second plug quantity be 2, the first plug, the second plug are inserted into the first fixation hole, second solid respectively
Determine hole and completes being detachably connected for the first fixed plate, the second fixed plate and bottom plate.
First plug and the first fixation hole dimensional fits, the second plug and the second fixation hole dimensional fits.
Elastic webbing is black stretch cord, and backplate surface is coated with white coating layer, facilitates the bullet for more intuitively observing black
Property band.
Distance of the length end of glass plate side away from corresponding floor length end is 5-10cm.
Lower surface of base plate is equipped with 4 suckers.
The utility model compared with prior art, has the advantages that.
When the utility model is used, the utility model is fixed on to by sucker the surface of give lessons blank or blackboard first,
The elastic webbing of four black can be directly shown as four line lattice, and teacher can be carried out on the surface of glass plate using signature pen
The writing of English, teacher draws four line lattice without scene, very convenient, while when writing a line and need to carry out next line writing, will
First fixed plate, the second fixed plate are removed from bottom plate, are then selected suitable first fixation hole, the second fixation hole, are inserted respectively
Enter the first plug, the second plug, is suitble to the writing of multirow English, improves the efficiency of giving lessons of English.
Detailed description of the invention
Fig. 1, an embodiment of the present invention structural schematic diagram；
Elastic string connection schematic diagram between first fixed plate, the second fixed plate in Fig. 2, Fig. 1；
Section A-A figure in Fig. 3, Fig. 1.
In figure: 1-1, the first fixed plate 1-2, the second fixed plate 2, elastic webbing 3-1, the first fixation hole 3-2, second are consolidated
Determine hole 4, glass plate 5, bottom plate 6-1, first support bar 6-2, second support bar 7, cavity 8-1, the first plug 8-2,
Two plugs.
Specific embodiment
The utility model is described further below with reference to embodiment and Figure of description.
As shown in Figure 1-3, four lines lattice demonstration tool described in the utility model, including rectangular base plate 5 and rectangular glass
4,5 length of bottom plate is greater than 4 length of glass plate, and bottom plate 5 is equal with 4 width of glass plate, 5 upper surface two sides edge of bottom plate and glass
4 lower surface two sides of plate along place be fixedly connected respectively by the first support bar 6-1 of bar shaped with second support bar 6-2, bottom plate 5 and
Bar shaped cavity 7 is formed between glass plate 4, and 4 elastic webbings, 2,42 both ends of elastic webbing are equipped in cavity 7 and are pierced by after cavity 7 respectively
It is equidistantly fixed with the first fixed plate 1-1, the second fixed plate 1-2,5 surface of bottom plate on the outside of 4 both ends of glass plate is respectively equipped with several
