The utility model provides a line drawing ware, line drawing standard and efficient, the function is various, and convenient to use can improve the chalk utilization ratio.
Description
Technical field
This utility model relates to teaching aid technical field, is specifically related to a kind of primary school Chinese pinyin lattice line drawing device.
Background technology
Primary school Chinese course is in teaching process, teachers association carries out pinyin marking to improve teaching efficiency to new Chinese character of learning, when pinyin marking, for improving the standardization of Pinyin writing, need to draw pinyin lattice on blackboard, and tradition teacher can only each drafting straight line to form pinyin lattice, drafting effect is relatively low.
Utility model content
Technical problem to be solved in the utility model is to provide the primary school Chinese pinyin lattice line drawing device of a kind of simple in construction, diverse in function.
For solving above-mentioned technical problem, this utility model offer techniques below scheme:
Parallel including two and be arranged at intervals with ruler plate, slide laterally the line drawing device being connected between two ruler plates, bottom surface, described ruler plate two ends is respectively fixed with sucker, described ruler plate medial surface is embedded with the chute of cross direction profiles, described chute extends to the other end from ruler plate one end, and the end face of described ruler plate is provided with length scale line；Described line drawing device includes that two ends are snug fit at the movable plate of two chutes, respectively with externally threaded four expansion links, the chalk that is homogeneously disposed in four chalk sleeves bottom movable plate, is fixed in each chalk sleeve, connection expansion link bottom is fixed on described chalk sleeve top, described expansion link top is placed in movable plate top, described expansion link being also associated with clamp nut through movable plate.
On the basis of such scheme preferentially, also include fixing chuck plate, being respectively embedded into draw-in groove on the end face of described ruler plate two ends, described fixing chuck plate two ends each extend over the fixture block corresponding with draw-in groove, and the corresponding end of two ruler plates is coordinated with the fixture block of fixing chuck plate achieved a fixed connection by draw-in groove.
On the basis of such scheme preferentially, described fixing chuck plate constitutes U-shape structure with two ends fixture block.
This utility model compared with prior art has the beneficial effect that the line drawing device that this utility model provides, and two ruler plate positions, and slides laterally drawing apparatus and can disposably draw out pinyin lattice, line drawing specification and efficiency height.Wherein, line drawing device can skid off between two ruler plates, it is achieved is independently operated, two ruler plates and can be employed as individually drawing straight line, and diverse in function is easy to use.Wherein, chalk can change use height by adjustable telescopic rod, improves chalk utilization rate.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.
See figures.1.and.2 and understand, primary school Chinese pinyin lattice line drawing device, parallel including two and be arranged at intervals with ruler plate 1, slide laterally the line drawing device 2 being connected between two ruler plates 1, bottom surface, ruler plate 1 two ends is respectively fixed with sucker 3, ruler plate 1 medial surface is embedded with the chute 11 of cross direction profiles, chute 11 extends to the other end from ruler plate 1 one end, and the end face of ruler plate 1 is provided with length scale line 13；Line drawing device 2 includes that two ends are snug fit at the movable plate 21 of two chutes 11, respectively with externally threaded four expansion links 22, the chalk 25 that is homogeneously disposed in four chalk sleeves 24 bottom movable plate, is fixed in each chalk sleeve 24, connection expansion link 22 bottom is fixed on chalk sleeve 24 top, expansion link 22 top is placed in movable plate 21 top through movable plate 21, clamp nut 23 it is also associated with on expansion link 22, when regulating chalk 25 and using height, screw clamp nut 23 and fix expansion link 22.
Also include fixing chuck plate 4, it has been respectively embedded into draw-in groove 12 on the end face of ruler plate 1 two ends, fixing chuck plate 4 two ends each extend over the fixture block 41 corresponding with draw-in groove 12, fixing chuck plate 4 and two ends fixture block 41 constitute U-shape structure, the corresponding end of two ruler plates 1 is coordinated with the fixture block 41 of fixing chuck plate 4 achieved a fixed connection by draw-in groove 12, utilizing fixing chuck plate 4 to connect fixing for two ruler plates 1, improve stability in the large, Convenient ruler plate 1 location quickly assembles with line drawing device 2.
The line drawing device that this utility model provides, two ruler plates 1 position, and slide laterally drawing apparatus 2 and can disposably draw out pinyin lattice, line drawing specification and efficiency height；Wherein, line drawing device 2 can skid off between two ruler plates 1, it is achieved is independently operated, two ruler plates 1 and can be employed as individually drawing straight line, and diverse in function is easy to use.Wherein, chalk 25 can change use height by adjustable telescopic rod 22, improves chalk utilization rate.
