Abstract

The utility model discloses a four-line three-grid scribing device for English teaching and relates to the teaching appliance technical field. The four-line three-grid scribing device for English teaching comprises a box body, a sliding block, a support spring, elastic rubber rings and a ruler. The four-line three-grid scribing device for English teaching is characterized in that the box body opens on the left side, and the sliding block matched with a cavity of the box body is sleeved inside the box body in a sliding mode. The support spring is connected between the right end of the sliding block and the right board surface of the box body. Four round grooves are evenly arranged on the left end surface of the sliding block. The elastic rubber rings are arranged in the inner walls of the round grooves. The inner diameter of the elastic rubber rings is smaller than the diameter of a chalk. Mutually symmetrical limiting pins are respectively fixed at the upper end and the lower end of the sliding block. The two limiting pins respectively penetrate through square through holes in the upper board surface and the lower board surface of the box body and then are exposed outside the box body. The left end of the lower board surface of the box body is connected with a dovetail joint, and the dovetail joint is sleeved in a dovetail groove. The dovetail groove is arranged on the ruler and matched with the dovetail joint. The four-line three-grid scribing device for English teaching is simple in structure and convenient to use, so that a teacher can rapidly draw a four-line three-grid shape conforming to standard specifications, and standard writing of English letters is facilitated.

Description

English teaching is with four lines, three lattice scribers
Technical field:
The utility model relates to the teaching aid technical field, and specifically a kind of English teaching is with four lines, three lattice scribers.
Background technology:
When taking lessons in English, for expressing the specification writing of letter, teacher usually need be at blackboard four lines, three lattice that draw, and teacher is drawing with a horizontal line of horizontal line of ruler when drawing four lines, three lattice.So not only complex operation, and the horizontal line depth of parallelism of drawing can't guarantee that the distance between the horizontal line can not well be held, and makes four lines, three lattice of drawing out nonstandard, is unfavorable for specification writing.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to use, and the English teaching that can draw out standard four lines three lattice on blackboard fast is with four lines, three lattice scribers.
The purpose of this utility model is achieved in that this English teaching comprises casing with four lines, three lattice scribers, slide block, support spring, the elastic caoutchouc circle, ruler, the uncovered box house slip suit in left side the slide block that adapts with its inner chamber, be connected with support spring between slide block right-hand member and the casing right panel face, be provided with four circular grooves on the slide block left side uniformly, circular spill inwall is provided with internal diameter less than the elastic caoutchouc circle of chalk diameter, slide block is being fixed symmetrical spacer pin respectively in two ends up and down, and two spacer pins pass on the casing respectively, be exposed at the casing outside after the rectangular through holes on the lower face; Casing lower face left end is connected with dovetail, and the dovetail slip cap is contained in the dovetail groove that adapts with it above the ruler.
During use, the circular spill interpolation on slide block is loaded onto chalk respectively, then ruler is close on the blackboard back mobile box, and the chalk in four circular grooves can be at blackboard four lines, three lattice of standard criterion that draw.
Advantage of the present utility model: simple in structure, easy to use, can make teacher's four lines, three lattice of standard criterion that on blackboard, draw fast, be conducive to the specification writing of English letter.
Description of drawings:
Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment:
Describe in further detail below in conjunction with the utility model of Fig. 1: this English teaching comprises casing 1 with four lines, three lattice scribers, slide block 2, support spring 3, elastic caoutchouc circle 4, ruler 5, the uncovered casing 1 slides within suit in left side the slide block 2 that adapts with its inner chamber, be connected with support spring 3 between slide block 2 right-hand members and the casing 1 right panel face, be provided with four circular grooves on slide block 2 left sides uniformly, circular spill inwall is provided with internal diameter less than the elastic caoutchouc circle 4 of chalk diameter, slide block is being fixed 6, two spacer pins 6 of symmetrical spacer pin respectively and is being passed respectively on the casing 1 in two ends about in the of 2, be exposed at casing 1 outside after the rectangular through holes on the lower face; Casing 1 lower face left end is connected with dovetail 7, and dovetail 7 slip caps are contained in the dovetail groove that adapts with it above the ruler 5.
