Description
Technical field
The present invention relates to English teaching appurtenance technical fields, are specifically related to a kind of three lattice of English teaching, four line line drawing
Device.
Background technique
Usually need to draw three lattice, four line in process of English teaching on blackboard for English writing on the blackboard, traditional drafting is only used
Chalk simply draws four horizontal lines, and spacing is uneven between horizontal line, and such line drawing mode is lack of standardization.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of structures to be simple and convenient to operate, the religion of the English of line drawing specification
Learn three lattice, four line line drawing device.
In order to solve the above technical problems, the present invention is the following technical schemes are provided: a kind of three lattice of English teaching, four line line drawing device,
The first ruler of linear type including cross direction profiles, the second ruler of linear type, the moving sleeve being vertically distributed, the moving sleeve can
What is moved up and down is socketed on the second ruler, is threaded with the fastening bolt for fastening on the moving sleeve, and described
One ruler one end is connected on moving sleeve；Length scale line is provided on first ruler and the second ruler；Described
Two ruler both ends are removably connected with support base respectively, and the support base bottom surface is fixed with sucker.
Preferential on the basis of above scheme, the support base is connected in the second ruler, is extended with snap-gauge on the support base,
Card slot corresponding with snap-gauge is offered on second ruler end face, the snap-gauge is inserted into card slot and on second ruler
Also it is threaded with the second bolt for fastening.
It is preferential on the basis of above scheme, it is detachably connected between first ruler and moving sleeve by attachment base,
The attachment base side is fixed on moving sleeve, other side side offers slot corresponding with the first ruler, and described
The third bolt and nut for fastening are threaded in one ruler insertion slot and on the attachment base.
Compared with the prior art, the invention has the beneficial effects that: line drawing device of the invention, the second ruler utilize suction
Disk realizes stable position, and the first ruler is used for line drawing, adjusts moving sleeve according to line drawing spacing demand, structure is simple, makes
With convenient, line drawing specification；Meanwhile second is detachably connected between ruler and support base, moving sleeve covers on the second ruler, just
Strong applicability is independently operated, in splitting out the second ruler from line drawing device.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the second ruler side view angle schematic diagram of the invention；
Fig. 3 is the first ruler overhead view of the invention.
Figure label are as follows: the first ruler of 1-, the second ruler of 2-, 3- moving sleeve, 4- fastening bolt, 5- length scale line,
6- support base, 7- sucker, 8- snap-gauge, 9- card slot, the second bolt of 10-, 11- attachment base, 12- slot, 13- third bolt, 14- spiral shell
It is female.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In the description of the present invention, it is to be understood that, term " longitudinal direction ", " transverse direction ", "upper", "lower", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown is merely for convenience of the description present invention, rather than the device or element of indication or suggestion meaning must
There must be specific orientation, be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.
Referring to figs. 1 to Fig. 3 it is found that a kind of three lattice of English teaching, four line line drawing device, the linear type first including cross direction profiles
Ruler 1, the second ruler of linear type 2, the moving sleeve 3 being vertically distributed, the moving sleeve 3 is moving up and down to be socketed on second
On ruler 2, the fastening bolt 4 for fastening is threaded on the moving sleeve 3；First ruler 1 and moving sleeve 3
Between be detachably connected by attachment base 11,11 side of attachment base is fixed on moving sleeve 3, other side side offers
Slot 12 corresponding with the first ruler 2, first ruler 1 are inserted into slot 12 and are threaded on the attachment base 11
Third bolt 13 and nut 14 for fastening.
Second ruler, 2 both ends are removably connected with support base 6 respectively, and 6 bottom surface of support base is fixed with sucker
7.The support base 6 is connected in the second ruler 2, and snap-gauge 8 is extended on the support base 6, is opened up on 2 end face of the second ruler
There is card slot 9 corresponding with snap-gauge 8, the snap-gauge 8 is inserted into card slot 9 and is also threaded on second ruler 2 and is used for
Second bolt 10 of fastening.
Length scale line 5 is provided on first ruler 1 and the second ruler 2.
Line drawing device of the invention, the second ruler 2 realize stable position using sucker 7, and the first ruler 1 is used for line drawing, root
