Abstract
The utility model provides a teaching blackboard enabling an English four-line grid to be drawn rapidly and relates to the teaching blackboard. The teaching blackboard enabling the English four-line grid to be drawn rapidly solves the problem that an existing teaching device used for drawing the English four-line grid is time-waste and labor-waste when being used for drawing the English four-line grid on the teaching blackboard. The upper end and the lower end of a blackboard body are respectively provided with a guide rail in the length direction. A sliding block is sleeved on each guide rail. A longitudinal coordinate meter is connected with the two guide rails in a sliding mode through the two sliding blocks. At least four through holes are evenly formed in the longitudinal coordinate meter in the length direction. A fixing hole which is perpendicular to a chalk fixing through hole is formed in the position of each through hole of the longitudinal coordinate meter. A fixing pin is arranged in each fixing hole and in threaded connection with one fixing hole. The teaching blackboard enabling the English four-line grid to be drawn rapidly is used for drawing the English four-line grid.
Description
Technical field
The utility model relates to a kind of blackboard for education of the English four line lattice that can draw fast.
Background technology
At present, traditional English traditional instruction still in the highest flight.In carrying out basic writing training and writing and teaching, English standard writing on the blackboard is used more extensive, for normalized written, the teacher need be at the blackboard corresponding English four line lattice that draw, during frame with the four line lattice that draw that go of delegation of long ruler delegation, also the someone has invented blackboard and the teaching equipments such as English, music teaching blackboard of four line lattice devices, English three ruling chalkers, parallel lines line assistor, band ruler, though can reach the purpose of the grid that draws like this, carry utensil at any time and also lose time very much with its frame.
To sum up, existing for the teaching equipment of drawing English four line lattice when blackboard for education is drawn English four line lattice, have the problem that wastes time and energy.
The utility model content
Existingly there is the problem that wastes time and energy for the teaching equipment of drawing English four line lattice in the utility model for solving when blackboard for education is drawn English four line lattice, and then a kind of blackboard for education of the English four line lattice that can draw fast is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the blackboard for education that can draw English four line lattice fast of the present utility model comprises the blackboard main body, described blackboard for education also comprises the along slope coordinate chi, two slide blocks and two guide rails, a guide rail respectively is installed on the upper and lower side of blackboard main body along its length, be set with a slide block on each guide rail, the along slope coordinate chi is slidingly connected by two slide blocks and two guide rails, uniformly along its length on the along slope coordinate chi be processed with at least four through holes, each through hole of coordinatometer is processed with and the orthogonal fixing hole of chalk fixed via, be provided with a steady pin in each fixing hole, steady pin is threaded with fixing hole.
The beneficial effects of the utility model are: the blackboard for education that can draw English four line lattice fast of the present utility model is provided with the along slope coordinate chi, be processed with through hole on the along slope coordinate chi, can be at the along slope coordinate chi many chalks of packing into when the teacher draws, draw many straight lines simultaneously, once finish the drafting of English four line lattice, compare with existing blackboard for education, shortened the time of drawing English four line lattice greatly, the time only draws 1/4th of the English four line lattice times spent for existing.
Description of drawings
The front view of the blackboard for education of Fig. 1 English four line lattice that can draw fast of the present utility model.
The specific embodiment
The specific embodiment one: as shown in Figure 1, the blackboard for education of the English four line lattice that can draw fast of present embodiment comprises blackboard main body 1, described blackboard for education also comprises along slope coordinate chi 2, two slide blocks 3 and two guide rails 4, a guide rail 4 respectively is installed on the upper and lower side of blackboard main body 1 along its length, be set with a slide block 3 on each guide rail 4, along slope coordinate chi 2 is slidingly connected by two slide blocks 3 and two guide rails 4, uniformly along its length on the along slope coordinate chi 2 be processed with at least four through hole 2-1, each through hole 2-1 place of coordinatometer 2 is processed with the orthogonal fixing hole 2-2 with chalk fixed via 2-1, be provided with a steady pin 5 in each fixing hole 2-2, steady pin 5 is threaded with fixing hole 2-2.
During use, chalk is fixed on corresponding through hole 2-1 place, and fixing by steady pin 5, move the drafting that along slope coordinate chi 2 can once be finished English four line lattice along horizontal direction.
The specific embodiment two: as shown in Figure 1, the described blackboard for education of present embodiment also comprises at least four molding powder pens cap 6, is provided with a molding powder pen cap 6 in each through hole 2-1.So design can prevent that chalk from fractureing, and improves the stability of setting-out.Other composition and connected mode are identical with the specific embodiment one.
