Abstract
T utility model discloses a T-square with a subsidiary ruler, which comprises a transverse ruler and a main ruler which are perpendicular with each other, wherein the main ruler is provided with a chute which is perpendicular with the transverse ruler, the subsidiary ruler with a pulley freely moves in the chute, and one edge of the subsidiary ruler which is provided with scale is parallel and level with one edge of the main ruler which is not provided with the scale. By arranging the subsidiary ruler which can freely slide and is provided with zero mark on the main ruler of the T-square, the T-square takes the scale of the subsidiary ruler as datum to easily measure any length due to zero mark on the subsidiary ruler; and can lengthways and freely move to take any point as a lengthways zero point, thereby being faster and more exact for drawing a horizontal line with any length.
Description
Technical field
The utility model relates to a kind of drawing tools, particularly a kind of T-square with secondary chi.
Background technology
In order to make horizontal line and vertical line orthogonal vertical when drawing, an end of existing T-square is fixed along chart board one end, utilizes a set square and T-square to cooperate the quadrature vertical line that just can draw.But when drawing vertical line, can not be very fast measure straight length, the number of lattice of lattice is.If can not guarantee again the line level of drawing so just to have influenced mapping speed and accuracy with other rulers.
The utility model content
The problem that the utility model solves is to provide a kind of T-square with secondary chi, and the straight line of random length in the vertical fast and accurately can draw.
The utility model is achieved through the following technical solutions:
A kind of T-square with secondary chi comprises mutually perpendicular crossfoot and main scale, has the chute vertical with crossfoot on main scale, and the secondary chi that has pulley moves freely at chute, and one side that secondary chi is provided with scale keeps concordant with one side that main scale is provided with scale.
Described secondary chi is provided with zero groove.
Existing main scale scale can not move, and the utility model is by being provided with the secondary chi of band zero groove that can be free to slide on the main scale of T-square, scale with secondary chi is a benchmark, there is zero graduation can measure random length easily above, and can vertically move freely, can be vertical zero point with the arbitrfary point; The horizontal line of drawing a random length like this is just faster more accurate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1, with the T-square of secondary chi, comprise mutually perpendicular crossfoot 1 and main scale 2, have the chute 3 vertical on the main scale 2 with crossfoot 1; Secondary chi 4 is provided with the pulley that adapts with chute 3, and secondary chi moves freely at chute by pulley, and one side that secondary chi is provided with scale keeps concordant with one side that main scale is provided with scale, and the scale that secondary chi is provided with comprises zero groove.
When drawing straight line, be benchmark with the scale of secondary chi, there is zero graduation can measure random length easily above, and can vertically moves freely, can be vertical zero point with the arbitrfary point; Can keep the line level of drawing again as the T-square of main scale, the horizontal line of drawing a random length like this is just faster more accurate.
Claims (2)
1. T-square with secondary chi, comprise mutually perpendicular crossfoot and main scale, it is characterized in that, on main scale, have the chute vertical with crossfoot, the secondary chi that has pulley moves freely on chute, and one side that secondary chi is provided with scale keeps concordant with one side that main scale is provided with scale.
2. the T-square of the secondary chi of band as claimed in claim 1 is characterized in that, the scale that secondary chi is provided with comprises zero groove.
