Description
Technical field
The utility model belongs to teaching aid field, particularly a kind of English teaching four line chi.
Background technology
Current teacher, when teaching English alphabet, needs on blackboard, depict four line three lattice, but the hand picture that teacher oneself is simple, the ruling drawn not too specification, and efficiency is low.
Summary of the invention
The utility model, in order to solve above asking a question, makes up the deficiency of conventional art, provides a kind of structure simple, setting-out specification, efficient English teaching four line chi.
The utility model is achieved by the following technical solution:
A kind of English teaching four line chi, it is characterized in that: comprise chi frame, guide wheel, handle and chalk clamp, chi frame is rectangle frame structure, and the rear end of chi frame has been provided with a rectangle gap, and the chi frame upper surface corresponding with rectangle gap is provided with graduation mark; The guide wheel of trend before and after being each side provided with one below the front end of chi frame; Chi frame is put and is installed with a handle; Rectangle gap through chi frame is provided with four chalk clamps, and chalk clamp is made up of pipe cap, neck and pipe clamp, and pipe cap is threaded with neck, and neck lower end is fixedly connected with pipe clamp, and pipe clamp is the cone-shaped tube cracked, and outside it, cover has clamp ring.
The beneficial effects of the utility model are, structure is simple, easy to use, and four chalk clamps that rectangle gap is installed can slide, and spacing, can draw four line lattice of different spacing, be applicable to different environments for use; The guide wheel of front and back trend can keep the linearity of setting-out, not flexible, setting-out specification.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is internal structure schematic diagram of the present utility model; Fig. 2 is the structural representation of chalk clamp of the present utility model.
In figure, 1 guide wheel, 2 chi framves, 3 chalk clamps, 4 graduation marks, 5 rectangle gaps, 6 handles, 7 pipe caps, 8 necks, 9 clamp rings, 10 pipe clamps.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.
English teaching four line chi of the present utility model, it is characterized in that: comprise chi frame 2, guide wheel 1, handle 6 and chalk clamp 3, chi frame 2 is rectangle frame structure, and the rear end of chi frame 2 has been provided with a rectangle gap 5, and chi frame 2 upper surface corresponding with rectangle gap 5 is provided with graduation mark 4; The guide wheel 1 of trend before and after being each side provided with one below the front end of chi frame 2; Chi frame 2 is put and is installed with a handle 6; Rectangle gap 5 through chi frame 2 is provided with four chalk clamps 3, chalk clamp 3 is made up of pipe cap 7, neck 8 and pipe clamp 10, and pipe cap 7 is threaded with neck 8, and neck 8 lower end is fixedly connected with pipe clamp 10, the cone-shaped tube of pipe clamp 10 for cracking, outside it, cover has clamp ring 9.
During use, chalk clamp be held on chalk clamp 3, regulate the spacing of four chalk clamps 3, hand-held handle 6, by guide wheel 1 side by blackboard, sliding in guide wheel 1 direction to draw four lines.This English teaching four line chi structure is simple, easy to use, and four chalk clamps that rectangle gap is installed can slide, and spacing, can draw four line lattice of different spacing, be applicable to different environments for use; The guide wheel of front and back trend can keep the linearity of setting-out, not flexible, setting-out specification.
