Description
Technical field
The utility model is related to teaching aid technical field, specially a kind of teaching ruler for high school mathematics teaching.
Background technology
Ruler is also known as chi, a chi, is for setting-out section, measures the instrument of length.Generally there is scale to measure length on chi.
In high school mathematics teaching, teacher often uses ruler, but existing ruler is only used for drawing straight line, and can not
Parallel lines are drawn well, also, can not keep the levelness and perpendicularity of straight line well when drawing straight line, give mathematics religion
Make troubles.In view of disadvantages described above, it is necessary to design a kind of religion for high school mathematics teaching for conveniently drawing parallel lines
Learn chi.
Utility model content
The purpose of this utility model is to provide a kind of teaching ruler for high school mathematics teaching, to solve above-mentioned background skill
The existing teaching ruler function of being proposed in art is single, can only draw straight line, and can not keep well straight line levelness and
Perpendicularity, and the problem of parallel lines can not be drawn.
To achieve the above object, the utility model provides following technical scheme：A kind of teaching for high school mathematics teaching
Chi, including fixed plate, handle, chute, bolt, ruler, scale, first level pearl, the second horizontal bead, internal thread sheath and suction
Disk, the top both sides of the fixed plate are respectively equipped with first level pearl and the second horizontal bead, and the sucker is located at the bottom of fixed plate
Portion, the fixed plate is provided with chute, and the left end bottom of the ruler is inlaid with internal thread shield in chute on the ruler
Set, the bolt is connected with internal thread sheath, and the ruler is provided with scale.
It is preferred that, it is vertical relation between the first level pearl and the second horizontal bead.
It is preferred that, the top of the fixed plate is provided with handle.
It is preferred that, the chute is convex shape structure.
Compared with prior art, the beneficial effects of the utility model are：This is used for the teaching ruler structure of high school mathematics teaching
Simply, it is easy to use, when drawing straight line, reference can be carried out by horizontal bead, be easy to draw out straight line horizontally or vertically, and
And, by regulating bolt, ruler is slided in chute, can easily draw out parallel lines, in the bottom of fixed plate provided with suction
Disk, the convenient fixation to the teaching ruler, also, can be easy to carry out the teaching ruler by the handle that is arranged at the top of fixed plate
Operation.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of teaching ruler for high school mathematics teaching,
Including fixed plate 1, handle 2, chute 3, bolt 4, ruler 5, scale 6, first level pearl 7, the second horizontal bead 8, internal thread sheath 9
With sucker 10, the top both sides of fixed plate 1 are respectively equipped with the horizontal bead 8 of first level pearl 7 and second, and sucker 10 is located at fixed plate 1
Bottom, fixed plate 1 is provided with chute 3, and the left end bottom of ruler 5 is inlaid with internal thread sheath in chute 3 on ruler 5
9, bolt 4 is connected with internal thread sheath 9, and ruler 5 is provided with scale 6.
In above-described embodiment, specifically, being vertical relation between the horizontal bead 8 of first level pearl 7 and second, in the level of drafting
Or during vertical straight line, respectively refer to the horizontal bead 8 of first level pearl 7 and second, you can the convenient levelness for determining straight line and
Perpendicularity.
In above-described embodiment, specifically, the top of fixed plate 1 is provided with handle 2, in use, handle 2 is grasped, can be square
Just to the operation of the teaching ruler.
In above-described embodiment, specifically, chute 3 is convex shape structure, the structure of convex shape makes the left end of ruler 5 be stuck in cunning
In groove 3, ruler 5 is positioned.
Operation principle：When being used for the teaching ruler of high school mathematics teaching using this, need first to being entirely used for high school mathematicses
The teaching ruler of teaching has the understanding in a structure, when in use, can more easily be used, this is used for high school mathematicses
The top both sides of the fixed plate 1 of the teaching ruler of teaching are respectively equipped with the horizontal bead 8 of first level pearl 7 and second, first level pearl 7 with
