Description
Technical field
The utility model relates to English teaching technical field, especially a kind of English teaching line folding ruler.
Background technology
When English teaching, specification is more write in order to make letter, teacher can draw out four line three lattice usually on blackboard, and when drafting four line three lattice, teacher can use the drafting of a ruler horizontal line horizontal line, so not only loaded down with trivial details, and the horizontal line depth of parallelism drawn cannot ensure, article four, the distance between horizontal line is bad assurance also, four line three lattice drawn out are nonstandard, be unfavorable for specification writing, when drawing three lattice four lines by instrument, existing drawing tool volume is larger, carry inconvenience, and existing marking-out rule needs adjustment one by one when the distance of adjustment four line chi, waste time and energy.
Summary of the invention
Technical assignment of the present utility model is a kind of English teaching line folding ruler provided for above the deficiencies in the prior art.
The utility model solves the technical scheme that its technical problem adopts: a kind of English teaching line folding ruler, comprise four horizon rules, connecting rod is hinged with respectively at the two ends of described horizon rule, by regulating the angle of horizon rule and connecting rod and then regulating the distance between four horizon rules, thus realize the object marking four line three lattice of different size, the adjacent connecting rod being positioned at described horizon rule the same side is hinged between two, fixed bar is fixedly connected with in the bottom of the connecting rod of left side lowermost end, through hole is provided with in the bottom of described fixed bar, the gag lever post of arc-shaped is fixedly connected with in the bottom of the horizon rule of described lowermost end, through hole on described gag lever post and fixed bar is connected, described gag lever post is provided with several spacing holes, described fixed bar is provided with locating hole with spacing hole corresponding position, bolt is provided with in described locating hole, with bolt location fixed bar and gag lever post mainly in order to make the angle of horizon rule and connecting rod fix, thus mark four line three lattice of different size fast and accurately.
The utility model has the advantage of: 1, the utility model is simply rational in infrastructure, easy to operate; 2, connecting rod of the present utility model can fold mutually, is convenient for carrying; 3, the utility model can mark four line three lattice of different size, simultaneously can the distance of quick adjustment four horizon rules, without the need to regulating in turn, time saving and energy saving, convenient and practical.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the side view after the utility model folds.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As depicted in figs. 1 and 2, a kind of English teaching line folding ruler, comprise four horizon rules 1, connecting rod 2 is hinged with respectively at the two ends of described horizon rule 1, by regulating the angle of horizon rule 1 and connecting rod 2 and then regulating the distance between four horizon rules 1, thus realize the object marking four line three lattice of different size, the adjacent connecting rod 1 being positioned at described horizon rule 1 the same side is hinged between two, fixed bar 3 is fixedly connected with in the bottom of the connecting rod 2 of left side lowermost end, through hole 7 is provided with in the bottom of described fixed bar 3, the gag lever post 6 of arc-shaped is fixedly connected with in the bottom of the horizon rule 1 of described lowermost end, described gag lever post 6 is connected with the through hole 7 on fixed bar 3, described gag lever post 6 is provided with several spacing holes 5, described fixed bar 3 is provided with locating hole with spacing hole 5 corresponding position, bolt 4 is provided with in described locating hole, fixed bar 3 is located with gag lever post 6 mainly in order to make horizon rule 1 fix with the angle of connecting rod 2 with bolt 4, thus mark four line three lattice of different size fast and accurately.
Its operation principle is: during use, first folding connecting rod 2 is opened, and then regulate fixed bar 3 and gag lever post 6 according to the specification of four required line three lattice, namely first bolt 4 is backed out, rotate horizon rule 1, distance between horizon rule 1 is reduced, then locating hole and spacing hole 5 is alignd, bolt 4 is penetrated and tightens.
Claims (1)
