Description
Technical field
A kind of chalker, more particularly to a kind of four ruling chalkers of English teaching are the utility model is related to, are belonged to
English teaching aid technical field.
Background technology
In English teaching, preferred necessary formal training writing basic training, teacher often will be in blackboard in teaching process
On draw four rulings, the English alphabet of standard is then write out in four lattice, most most common method is existed with ruler and set square
Setting-out on blackboard, but this line drawing method teacher will take set square on the other hand, ajust the position of ruler on the other hand, then both taken with a hand
Set square takes ruler again, and another hand is taken chalk setting-out, is inconvenient, and draw several times, not only hand fatigue, also loses time more, draws
The length of the line gone out can not run through whole blackboard, it is also necessary to which single line is repeatedly drawn, spliced.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of four ruling chalkers of English teaching,
The correct position for being shifted device in blackboard onto at the outside of blackboard, use by installing the present apparatus, by promoting cross slide
Bar slides laterally, and four paintbrushes is drawn four equal rulings of four stripe pitch on blackboard, and once-through operation draws one on blackboard
Complete four ruling of the bar through left and right.Released when having drawn outside blackboard downwards, be not take up blackboard space.
The technical scheme in the invention for solving the technical problem is：Four ruling chalkers of English teaching,
It is by iron bottom plate bar, ∏ shape cross rails plate, L-shaped sideskid, magnetic stripe, cross slide bar, cross slide, bolt, turn, underlay
Circle, upper gasket 1, sliding sleeve, nut, paintbrush, elastic clip pen container, with flat foxy bolt, packing ring, wing nut, adjusting screw rod, dome
Plate, stud composition.Iron bottom plate bar is fixed with blackboard on both sides, ∏ shapes cross rail plate lower end passes through the magnetic stripe in its groove and iron bottom
Lath is slidably connected, on the outside of the ∏ shape cross rail plates below be fixed with L-shaped sideskid, L-shaped sideskid respectively with outside iron bottom plate bar
The side trench that side and its outside are provided with is slidably connected.Two strip openings, cross slide are provided with above ∏ shape cross rail plates
Bar lower end passes through on two strip openings, bolt, turn, lower gasket, sliding sleeve, upper gasket, nut and cross slide bar
Two circular holes are slidably connected with ∏ shape cross rail plates, cross slide are fixed with cross slide bar, two cross slides inner sides are respectively
It is slidably connected with ∏ shape cross rail plates two sides.Long sliding hole, middle slide opening, short cunning are from top to bottom respectively equipped with cross slide bar
Hole and a circular hole, elastic clip pen container is connected with circular hole by stud, packing ring, wing nut, long sliding hole, middle slide opening,
Elastic clip pen container is connected with by may move with flat foxy bolt, packing ring, wing nut respectively on short slide opening, in stud and three
Adjusting screw rod is connected on screwed hole of centre with flat foxy bolt, is provided with adjusting screw rod outer end and is cut mouth, adjusts spiral shell
Bar the inner puts in elastic clip pen container and is connected with dome plate, elastic opening is provided with elastic clip pen container perisporium, in elastic pen clip
Paintbrush is connected with by elastic opening and dome plate in cylinder.Described stud, with flat foxy bolt outer face tag line is provided with, it is right
Stud, the tag line with flat foxy bolt is answered to be respectively equipped with graduation mark on cross slide bar.
The beneficial effects of the utility model are：By magnetic stripe adhesive ∏ shape cross rail plates, with hand pushing movable flexible and convenient, draw
Spacing is by tag line and graduation mark to position adjustment, and quick and precisely, cross slide bar passes through two sliding sleeves and ∏ shapes for adjustment
Cross rail plate is slidably connected, and connection reliably slides freely, and apparatus structure is simple, easy to use, in that context it may be convenient to is drawn by paintbrush
The consistent setting-out of four width going out, using effect is very good, is a kind of to have very much practical value, four to be worth of widely use
Ruling chalker.The correct position for being shifted device in blackboard onto at the outside of blackboard, use by installing the present apparatus, pass through
Promote cross slide bar to slide laterally, four paintbrushes is drawn four equal rulings of four stripe pitch on blackboard, once-through operation exists
Complete four ruling through left and right is drawn on blackboard.Released when having drawn outside blackboard downwards, be not take up blackboard space.Teacher makes
One hand can of used time completes operation, very convenient, time saving and energy saving.
