Abstract
The utility model belongs to the drawing tool that machinery drawing was used especially relates to a T square. The technical scheme of the utility model is that: the T-square comprises a vertical ruler and a transverse ruler, wherein a boss is arranged at one end of the vertical ruler, and a groove matched with the boss is formed in the longitudinal direction of the ruler body of the transverse ruler. Can slide one side to the recess of erecting the chi on the horizontal ruler according to the drawing needs, then the length of horizontal ruler one side is elongated, makes the size of measuring and drawing more accurate, slides out in erecting the chi from the recess of horizontal ruler, then two chi parts can be separately as the ruler use to portable and placing.
Description
Technical field
The utility model belongs to the drawing instrument that mechanical drawing is used, and relates in particular to a kind of T-square.
Background technology
The personnel that begin to learn mechanical drawing at present draw on drawing paper with drawing board and T-square, traditional T-square is to be made of crossfoot and perpendicular chi, one termination portion of perpendicular chi is connected with the center fixation of crossfoot, because crossfoot is shorter, the crossfoot of the horizontal direction when drawing may just can not correctly be measured the drafting size, make and draw difficulty, render speed is slow, and size is made mistakes easily, again since T-square than the great achievement T-shaped, be not easy to carry, make troubles to the user.
Summary of the invention
The purpose of this utility model, be to overcome the deficiencies in the prior art, and provide a kind of T-square, hard chi in this technical scheme can slide on crossfoot, may slide into a side of crossfoot during drawing, and has prolonged the length of crossfoot one side, make the drafting size just accurate, the time spent can be perpendicular chi and crossfoot separately, takes up an area of for a short time, conveniently places or carry.
For solving the problems of the technologies described above, the technical solution of the utility model is: T-square, comprise hard chi and crossfoot, an end of described perpendicular chi has boss, the crossfoot blade vertically on the groove that matches with boss is arranged.Boss can slide in the groove on crossfoot, when skidding off in the groove of boss from crossfoot on the perpendicular chi then crossfoot and perpendicular chi separately, at this moment two chis can as two independently ruler use.
T-square described in the utility model is the transparent plastic material.
The beneficial effects of the utility model are: T-square comprises hard chi and crossfoot, at an end of perpendicular chi boss is arranged, the crossfoot blade vertically on the groove that matches with boss is arranged.Can slide into a side to perpendicular chi along the groove on the crossfoot according to the drawing needs, then the length of crossfoot one side is elongated, make the size of measuring and drawing more accurate, perpendicular chi is skidded off from the groove of crossfoot, and then two chis separately can be separately use when ruler, and are easy to carry and place.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is along the profile of A-A direction among Fig. 1.
Among the figure: the 1-crossfoot, the 2-groove, 3-erects chi, the 4-boss.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The specific embodiment
According to illustrated in figures 1 and 2, T-square comprises hard chi 3 and crossfoot 1, and an end of described perpendicular chi 3 has boss 4, crossfoot 1 blade vertically on the groove 2 that matches with boss 4 is arranged, T-square is the transparent plastic material.
Claims (2)
1, T-square comprises hard chi and crossfoot, it is characterized in that: an end of described perpendicular chi has boss, the crossfoot blade vertically on the groove that matches with boss is arranged.
2, T-square according to claim 1 is characterized in that: described T-square is the transparent plastic material.
