Description
Technical field
The utility model is related to field of Education and teaching, more particularly to a kind of lattice setting-out teaching aid of four line of novel English three.
Background technology
With the development of international community, exchange it is close, English also seems more and more important as an International Language.
In English teaching, blackboard writing on the blackboard is be unable to do without, during writing on the blackboard, for the writing of specification English alphabet, allows the student can be intuitively
See the sequential write of pinyin and English letter, generally require to draw the equidistant straight line in four roads with ruler on blackboard, and classroom
The time of teaching is limited, it is necessary to spend many times, because ruler length is less than blackboard length, so it is difficult to accurate draw
Equidistant lattice of four line three between outlet and line.
Disclose a kind of lattice instrument of four line three suitable for English teaching, its Application No. on December 16th, 2015
CN201520454854.7, the light that the device is broken forth using infrared lamp on blackboard is write, and is adjusted by compression spring
Save the distance between light.But this device is existed：Light is weak, spring is fragile, accuracy is low, baroque shortcoming.
Utility model content
Technical problem to be solved in the utility model is：A kind of lattice setting-out teaching aid of four line of novel English three is provided, to solve
Certainly the problem of above-mentioned background technology.
The technical scheme that the utility model is used by solution the problem of set forth above is：
A kind of lattice setting-out teaching aid of four line of novel English three, including mounting bracket 2, wooden unit A3, laser lamp 4, slide rail 7 and wooden unit

The described side of mounting bracket 2 is provided with handle 5, and the upper end of handle 5 is connected with wooden unit A3, the lower end of handle 5 and wooden unit
B9 connections, conveniently move up and down this teaching aid.
Described laser lamp 4 is fixed on magnet 6 by geometrical clamp 1, and geometrical clamp 1 is pull-in on magnet 6, and convenient dismounting is more
Change laser lamp.
Described laser lamp 4 is red laser lamp, facilitates teacher to observe.
Described laser lamp 4 is concordant with blackboard surface, facilitates teacher to observe.
Described slide rail 7 is provided with scale, quickly and accurately the distance between light regulating.
The number of described recess hole 8 is 8-12, and the number of recess hole is adjusted according to the specific height of blackboard.
Utility model works principle：Setting-out teaching aid is arranged on the left of blackboard, demand is write according to teacher, cunning is utilized
Scale on rail, with the distance between hand adjustment section adjacent magnets so that four laser lamps, irradiated on blackboard surface four it is parallel
The distance between equidistant line changes, so that the spacing of the lattice of four line three is adjusted so that the utility model is adapted to each
Individual teacher；After a line letter is write completely, this teaching aid is lifted by handle, is then put into next group of recess hole, this teaching aid exists
The next group of lattice of four line three are irradiated on blackboard surface.
The utility model beneficial effect is：The utility model is simple in construction, easy to use, high working efficiency；Laser lamp
Replace infrared lamp observing effect more preferable；, can quick and precisely the distance between light regulating using the graduated scale on slide rail；Wooden unit
B and wooden unit A, using the mode that is connected together, can allow this teaching aid to be quickly found out next a series of paintings line position with recess hole.
