Description

A kind of English teaching chalker

Technical field

The utility model belongs to teaching aid field and in particular to a kind of English teaching chalker.

Background technology

In English teaching, especially in the teaching process of word and phonetic symbol, instructors are needed to draw English four line lattice, ability The more specification that word and phonetic symbol are write, but light relies on feel and eyes to be difficult to draw four line lattice being parallel to each other, once It is lack of standardization that four line lattice are drawn, and may result in the letter that teacher writes and phonetic symbol deformation, this deformation still not unsightly, but also Can cause to obscure it is impossible to understand the regular literary style of word and phonetic symbol to students.

Utility model content

In order to solve the problems referred to above of prior art presence, the utility model provides a kind of English teaching chalker.

The technical scheme that the utility model is adopted is:

A kind of English teaching chalker, is to be made up of two cross bars, two vertical poles and mobile scribe structure, described two Individual cross bar is fixed between two vertical poles, and through mobile scribe structure and mobile scribe structure can be in two horizontal strokes for two cross bars Slide on bar, described mobile scribe structure is to be made up of sliding bar, chalk fixed structure and handle, two cross bars pass through and slide Perforation on bar, chalk fixed structure is fixed on sliding bar at equal intervals, shakes hands to be individually fixed in for u-shaped structure, its two ends The two ends of sliding bar.

As further improvement of the utility model, described chalk fixed structure is by fixed block, push rod, nut and powder Pen cap pipe is constituted, and described fixed block bolt is fixed on sliding bar, and chalk sleeve passes through and be fixed on fixed block, push rod interior Portion has been threaded connection the threaded rod matching with nut, and the afterbody of threaded rod is located in chalk sleeve, under chalk sleeve Portion is provided with fixing bolt.

As further improvement of the utility model, the inner side of one of vertical pole is provided with two suckers.

The beneficial effects of the utility model are: English teaching chalker of the present utility model, simple to operate, user Just, only device need to be placed on blackboard, pull handle, you can four lines being parallel to each other are drawn on blackboard, and device is whole Body Stability Analysis of Structures, chalk stationarity is also preferable, brings great convenience to the teaching of teacher, improves the teaching effect on classroom Rate.

Specific embodiment

As shown in figure 1, a kind of English teaching chalker of the present utility model, it is by 1, two vertical pole 2 and of two cross bars Mobile scribe structure 3 is constituted, and two described cross bars 1 are fixed between two vertical poles 2, and the inner side of one of vertical pole 2 is provided with Two suckers 13, for the vertical pole 2 of non-hand-held side is fixed on blackboard, make structure during line more stable；Two cross bars 1 Pass through mobile scribe structure 3 and mobile scribe structure 3 can slide on two cross bars 1；Described mobile scribe structure 3 is 6 it is made up of (as Fig. 2) sliding bar 4, chalk fixed structure 5 and handle, two cross bars 1 pass through the perforation 7 on sliding bar 4, chalk The quantity of fixed structure 5 is four, and four chalk fixed structures 5 are fixed on sliding bar 4 at equal intervals；Handle 6 is u-shaped knot Structure, its two ends are individually fixed in the two ends of sliding bar 4, and when needing line, user only need to pull handle 6, you can band Dynamic sliding bar 4 is mobile, and sliding bar 4 drives four chalk fixed structures 5 to draw four line lattice on blackboard；Described chalk fixed knot Structure 5 is to be made up of (as Fig. 3) fixed block 8, push rod 9, nut 10 and chalk sleeve 11, and described fixed block 8 bolt is fixed on cunning In lever 4, chalk sleeve 11 passes through and is fixed on fixed block 8, and the inside of push rod 9 has been threaded connection is matched with nut 10 Threaded rod, the afterbody of threaded rod is located in chalk sleeve 11, when chalk expose shorter when, can be with turn nut 10, with spiral shell Chalk will be released by the threaded rod that cap 10 matches；The bottom of chalk sleeve 11 is provided with fixing bolt 12, when the length of chalk When suitable, can turn bolt 12 by fixing for chalk with chalk sleeve 11 in.

Using front, first chalk is loaded standby in four chalk fixed structures 5；During use, can be first by with sucker 13 Vertical pole 2 is fixed on suitable position using sucker 13, and then user's proficiency pins another vertical pole 2, and another pulls dynamic drawing Hand 6, you can draw four line lattice.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model Other various forms of products, however, making any change in its shape or structure, every have same as the present application or phase Approximate technical scheme, all falls within protection domain of the present utility model.
