Abstract
一种带副尺的丁字尺，包括互相垂直的横尺和主尺，在主尺上开有与横尺垂直的滑槽，带有滑轮的副尺在滑槽自由移动，副尺设有刻度的一边与主尺设有刻度的一边保持平齐。本实用新型通过在丁字尺的主尺上设有可自由滑动的带零刻线的副尺，以副尺的刻度为基准，上面有零刻度能很容易的量出任意长度，而且能够纵向自由移动，可以以任意点为纵向零点；这样画一条任意长度的水平线就更快更准确了。
A T-shaped ruler with an auxiliary ruler, including a horizontal ruler and a main ruler perpendicular to each other, a chute perpendicular to the horizontal ruler is opened on the main ruler, the auxiliary ruler with a pulley moves freely in the chute, and the auxiliary ruler is provided with a scale One side of the main scale is kept flush with the side with the scale. The utility model is provided with a freely slidable auxiliary ruler with a zero scale line on the main ruler of the T-shaped ruler. Taking the scale of the auxiliary ruler as a reference, there is a zero scale on it, which can easily measure any length, and can be freely longitudinally. For moving, any point can be used as the vertical zero point; it will be faster and more accurate to draw a horizontal line of 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.
