Description
Technical field
The utility model relates to the technical field of Chinese teaching aid, is specially four line three lattice line-plotting devices of language teaching.
Background technology
In Chinese language process, usually need teacher on blackboard, draw three rulings.In prior art, teacher also just relies on ruler, divides and draws four straight lines for four times, to form three lattice.
In Chinese language conventional teaching, often to use the specification writing that four line three lattice carry out guiding student study phonetic alphabet.Teacher often needs on blackboard, to draw four line three lattice with ruler, but there will be and loses time, or situation oblique for line drawing; Sometimes teachers association prepares the blank sheet of paper of four line three lattice finished in advance, and shortcoming compares to lose time and material, can not supplement in time after being finished.
But at present, most teacher is by with chalk direct Freehandhand-drawing four line three lattice, but due to the length of blackboard and the writing on the blackboard custom of individual, also often occurs four line three lattice to draw partially to draw oblique situations, to such an extent as to affect quality of instruction.The patent No. is the utility model patent of CN203543459, and its name is called English writing scriber, which solve teacher in process of English teaching and directly draw the problem of four line three lattice with hand, but its complex structure, manufacturing cost is high, are unfavorable for the teaching of poverty-stricken area.The patent No. is the utility model patent of CN202541125, its name is called a kind of four line three lattice scribers, its structure is simple, which solve teacher in process of English teaching directly draws the problem of four line three lattice with hand, but its long version can not be relatively fixed on blackboard, namely its long slab in line drawing process can slide by relative blackboard, have impact on its setting-out effect, reduce quality of instruction.
Therefore, it is simple, cheap for manufacturing cost, easy to use and improve four line three lattice line-plotting devices of the language teaching of efficiency of teaching and Classroom instruction quality that we have developed a kind of structure, its concrete target to utilize the material easily obtained to make a teaching aid easy and simple to handle, four line three lattice parallel to the ground can be drawn easily, no longer by the restriction of when and where on blackboard.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, cheap for manufacturing cost, easy to use and improves four line three lattice line-plotting devices of the language teaching of efficiency of teaching and Classroom instruction quality; Its specific purposes to utilize the material easily obtained to make a teaching aid easy and simple to handle, can draw four line three lattice parallel to the ground easily, no longer by the restriction of when and where on blackboard.
In order to realize described object, the utility model specifically adopts following technical scheme:
Four line three lattice line-plotting devices of language teaching, it comprises fixed head body 1, skateboard body 2, fixed connection apparatus 3, guide rail 4, pulley 5, and chalk socket 6, hand is 7.It is characterized in that: described fixed head body 1 is by penetrating two groove 101 trisections, and fixed head body 1 upper surface is provided with guide rail 4; Described skateboard body 2 lower surface is provided with the pulley 5 be connected with guide rail 4; Described fixed head body 1 bottom surface is provided with fixed connection apparatus 3; Described skateboard body 2 is provided with chalk socket 6.
The surface of described fixed head body 1 is provided with lever 8.
Described skateboard body 2 is provided with the identical chalk socket 6 of four line spaces.
The chalk that two chalk sockets 6 in the middle of described skateboard body 2 are installed pierces into groove 101 respectively and directly contacts with blackboard.
Madial wall and skateboard body 2 outer ledge of two chalk sockets 6 on described skateboard body 2 both sides are in same level.
Described skateboard body 2 is provided with hand 7.
Height≤the 1.2mm of described guide rail 4.
Described fixed connection apparatus 3 is small magnet block.
Described fixed head body 1 four jiaos of places are fillet, and the radius of corner R in the left upper right corner
1the radius of corner R at about > inferior horn place
2.
Four line three lattice line-plotting devices of the utility model language teaching, described fixed head body 1 is by penetrating two groove 101 trisections, and fixed head body 1 upper surface is provided with guide rail 4; Described skateboard body 2 lower surface is provided with the pulley 5 be connected with guide rail 4; Described guide rail 4 coordinates with pulley 5, facilitates skateboard body 2 opposing fixed plate body 1 and slides, make chalk not frangibility, and the line quality drawn is high; Described fixed head body 1 bottom surface is provided with fixed connection apparatus 3, and it makes the relative blackboard fixation of this device, can not produce slip, improve setting-out effect and quality of instruction.
Compared with prior art, the beneficial effects of the utility model are: one, described guide rail 4 coordinates with pulley 5, facilitate skateboard body 2 opposing fixed plate body 1 and slide, make chalk not frangibility, and the line quality drawn is high; Two, described fixed head body 1 bottom surface is provided with fixed connection apparatus 3, and it makes the relative blackboard fixation of this device, can not produce slip, improve setting-out effect and quality of instruction; Three, described fixed head body 1 four jiaos of places are fillet, in use avoid the problem of the user that damages, and the radius of corner R2 at radius of corner R1 about the > inferior horn place in the left upper right corner avoid in use procedure by teaching aid take fall situation; Four, its simplicity of design novel, practical, draw materials easily, structure is simple, be easy to operation, stable performance, safe and reliable, cheap, be convenient to self-control popularization.
