Abstract
The utility model relates to a T square is used in drawing teaching, including horizontal chi and vertical chi, horizontal chi distributes with vertical chi mutually perpendicular, along the length direction of horizontal chi has seted up the spout, vertical chi along the spout slides at the horizontal upper part of cunkou pulse, vertical chi constitutes extension rule by first ruler, second ruler and third ruler, grips the handle at the end -to -end connection of vertical chi, connect through the set screw between horizontal chi and the vertical chi. The utility model has the advantages of simple structure and reasonable design, spout sliding connection on the convenient operation, horizontal chi and vertical chi, so transversely the chi can slide in the spout to extending structure is set to through horizontal chi to the convenient parallel lines that draw up, and the longer straight line that can draw up grips the handle, portable through being provided with.
Description
Technical field
The utility model relates to realia technical field, particularly relates to a kind of drawing teaching T-square.
Background technology
Existing teaching ruler, is made up of four rulers, two perpendicular chis, uses inconvenience, and time of act is grown very tired, and not portable, can not fold, takes up space large when putting.
In the process of carrying out drawing teaching, often can draw parallel lines, the mode generally drawn parallel lines now is with a ruler as benchmark, moves, draw parallel lines in this approach with one piece of set square along ruler.But this mode operates more loaded down with trivial details, drastically influence the efficiency of teaching of teacher.In addition, usually there will be the situation that ruler falls short of when sometimes drawing straight line, this is the thing making instructors have a bad headache.Therefore derive a kind of T-square, but T-square of the prior art can not stretch according to the needs of length on the one hand, be not easy to carry on the other hand, lack the device of movement simultaneously, make can not realize between horizontal chi and longitudinal ruler moving.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of drawing teaching T-square.
The utility model is achieved through the following technical solutions:
A kind of drawing teaching T-square, comprise horizontal chi and longitudinal ruler, described horizontal chi and the mutual vertical distribution of longitudinal ruler, length direction along described horizontal chi offers chute, described longitudinal ruler slides in horizontal chi along described chute, described longitudinal ruler forms shrinkage-rule by the first ruler, the second ruler and the 3rd ruler, is connected with grab handle at the end of longitudinal ruler.
As optimal technical scheme of the present utility model, connected by set screw between described horizontal chi and longitudinal ruler.
As optimal technical scheme of the present utility model, the upper surface of described horizontal chi and longitudinal ruler is provided with graduation mark.
As optimal technical scheme of the present utility model, described chute is bar-shaped trough.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to operate, horizontal chi is connected with the slide on longitudinal ruler, so horizontal chi can slide in chute, to draw parallel lines easily, be arranged to stretching structure by horizontal chi, longer straight line can be drawn, by being provided with grab handle, be easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the horizontal chi of 1-; 2-longitudinal ruler; 3-chute; 4-grab handle; 5-set screw; 20-first ruler; 21-second ruler; 22-the 3rd ruler.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of drawing teaching T-square, comprise horizontal chi 1 and longitudinal ruler 2, the upper surface of described horizontal chi 1 and longitudinal ruler 2 is provided with graduation mark, described horizontal chi 1 and longitudinal ruler 2 vertical distribution mutually, length direction along described horizontal chi 1 offers chute 3, described longitudinal ruler 2 slides in horizontal chi 1 along described chute 3, and described longitudinal ruler 2 forms shrinkage-rule by the first ruler 20, second ruler 21 and the 3rd ruler 22, is connected with grab handle 4 at the end of longitudinal ruler 2.
Described chute 3 is bar-shaped trough, is connected between described horizontal chi 1 and longitudinal ruler 2 by set screw 5.
Horizontal chi is connected with the slide on longitudinal ruler, and so horizontal chi can slide in chute, to draw parallel lines easily, being arranged to stretching structure by horizontal chi, can drawing longer straight line, by being provided with grab handle, being easy to carry.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
