Abstract
The utility model discloses a T-square belonging to a plotting instrument, in particular to a multi-functional T-square, comprising a main scale, a turn scale, a vernier, a spring clamp, etc. The utility model has the function of a plotter, the structure is simple, the price is low, and the plotting is convenient.
Description
The utility model is about drawing instrument---the utility model of T-square, particularly multi-functional T-square.
Known T-square is generally drawn horizontal straight line and is used on chart board, and draw vertical vertical line or at any angle straight line must have set square or protractor to cooperate just to make, inconvenience during drawing is though plotter has the function of T-square, set square, protractor sum total, but price is more expensive, complex structure.
The utility model provides a kind of T-square, and it is simple in structure, and low price has the function of plotter.
Its solution is: have one with vernier 180 ° of scale values and that can laterally be free to slide on main scale on the main scale of drawing horizontal straight line, the commentaries on classics chi that also can lock on each scale value that can swing 180 ° is being housed on the center of circle of 180 ° of scale values of vernier, and they can make arbitrary line in same plane.One end of main scale is equipped with main scale and is fixed together and mutually perpendicular station meter, and the other end has the chucking chi that can laterally slide and lock in the main scale optional position on main scale, to adapt to the chart board of different size.The station meter at main scale two ends and chucking chi are parallel to each other, and their back are equipped with the Spring Card of adjustable clamping force respectively, so that chart board uses during greater than 30 ° in gradient.It is constant to remove chucking chi and spring khaki drawing function on the chart board that keeps flat.
This utility model has the function of T-square, set square, three kinds of drawing instruments of protractor.And structure is simpler than plotter.
Device and function situation that concrete structure foundation of the present utility model the utility model proposes:
Accompanying drawing 1, the front view of multi-functional T-square.Accompanying drawing 2 is vertical views.This utility model structure comprises the main scale (1) that has scale value, has the commentaries on classics chi (2) of scale value, vernier (3); Station meter (4), chucking chi (5), Spring Card (6), retainer spring sheet (7), set screw (8), handle (9) works the reed (12) of eliminating mismatch error between chucking chi set lever (10) and main scale and the vernier.
Accompanying drawing 2 is vertical views, wherein number for (11) be the drawing board of drawing in addition, to show the function of use situation of multi-functional T-square on vertical chart board.To tighten chi (5) during use and push chart board on one side along main scale (1) by direction shown in the arrow in the accompanying drawing 1, make retainer spring sheet (7) contact chart board (11) edge, tighten chucking chi handle (10), at this moment adjustable spring card (6) has been stuck in the chart board back, adjust set screw (8) and make this device, can on vertical chart board, use with not free-falling and don't tightly.
Accompanying drawing 3, multi-functional T-square is keeping flat or gradient is not more than 30 ° chart board operating position.Remove regulating spring card (6), chucking chi (5).Time spent station meter (4) is close to chart board (11) on one side, can the horizontal straight line of picture along main scale (1).Change chi (2) and aim at the 90 ° of scales or the arbitrary scale of vernier (3), chi handle (9) is changeed in locking, along changeing chi (2) can draw vertical line or straight line at any angle.Situation when commentaries on classics chi shown in Figure 3 (2) is 60 ° or 120 °.
Claims (1)
1, multi-functional T-square, an end of drawing the main scale (1) of horizontal straight line has a station meter (4) and its to be fixed together and is orthogonal.It is characterized in that:
Have on the described main scale (1) that has a scale one that have 180 ° of scale values and can go up the free vernier (3) that laterally slides at main scale (1).Being equipped with one in the heart at the Round of (3) 180 ° of scale values of vernier can commentaries on classics chi (2) 180 ° of swings and that can lock on each scale value.
