Abstract
The invention belongs to the field of teaching appliances, and especially relates to an English teaching four-line ruler, characterized by comprising a ruler frame, guiding wheels, a handle, and chalk clamping pipes. The ruler frame is in a rectangular frame structure. The rear end of the ruler frame is provided with a rectangular gap, and the upper surface of the ruler frame, corresponding to the rectangular gap, is provided with a scale mark. Two guiding wheels moving front and back are respectively arranged on the left side and the right side of the lower part of the front end of the ruler frame. The handle is fixedly arranged on the upper part of the ruler frame. Four chalk clamping pipes are arranged passing through the rectangular gap of the ruler frame. The chalk clamping pipe is formed by a pipe cap, a pipe neck, and a pipe clamp. The pipe cap is connected with the pipe neck by threads. The lower end of the pipe neck is fixedly connected with the pipe clamp. Beneficial effects of the ruler are that structure is simple, use is convenient, the four chalk clamping pipes arranged in the rectangular gap can slide, and the distance can be adjusted, the ruler can draw four-line grids in different distances, and is suitable to be used in different use environment. The guiding wheels moving front and back can maintain linearity of the drawn lines, and the lines do not easily curve, and the lines are standard.
Description
Technical field
The invention belongs to teaching aid field, particularly to a kind of English teaching four line chi.
Background technology
If current teacher, when teaching English alphabet, needs to depict four line three lattice on blackboard, but the simple hands of teacher oneself is drawn, the ruling drawn less specification, and efficiency is low.
Summary of the invention
The present invention is to solve problem mentioned above, make up the deficiency of conventional art, it is provided that a kind of simple in construction, setting-out specification, efficient English teaching four line chi.
The present invention is achieved through the following technical solutions:
A kind of English teaching four line chi, it is characterised in that: including 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 rectangular gap, and the chi frame upper surface corresponding with rectangular 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；Put on chi frame and be installed with a handle；Rectangular 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 threadeded with neck, and neck lower end is fixedly connected with pipe clamp, and pipe clamp is the cone-shaped tube cracked, and is cased with clamp ring outside it.
The invention has the beneficial effects as follows, simple in construction, easy to use, four chalk clamps that rectangular gap is installed can slide, and regulates spacing, can draw four line lattice of different spacing, it is adaptable to different use environment；The guide wheel front and back moved towards can keep the rectilinearity of setting-out, the most flexible, setting-out specification.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the internal structure schematic diagram of the present invention；Fig. 2 is the structural representation of the chalk clamp of the present invention.
In figure, 1 guide wheel, 2 chi framves, 3 chalk clamps, 4 graduation marks, 5 rectangular gap, 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 invention.
The English teaching four line chi of the present invention, it is characterized in that: include 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 rectangular gap 5, and chi frame 2 upper surface corresponding with rectangular 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；Put on chi frame 2 and be installed with a handle 6；Rectangular 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 threadeded with neck 8, and neck 8 lower end is fixedly connected with pipe clamp 10, pipe clamp 10 is the cone-shaped tube cracked, and is cased with clamp ring 9 outside it.
During use, being clamped in by chalk 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 simple in construction, easy to use, four chalk clamps that rectangular gap is installed can slide, and regulates spacing, can draw four line lattice of different spacing, it is adaptable to different use environment；The guide wheel front and back moved towards can keep the rectilinearity of setting-out, the most flexible, setting-out specification.
