Abstract
Novel T-square includes crossfoot, perpendicular ruler, and the crossfoot is equipped in the width direction, " convex " type groove, and trough rim sets that there are two gears.Perpendicular ruler top is divided into " convex " type, closes with horizontal ruler slot tone, and both sides are equipped with the rack gear that concaves, and with gear inosculation, bottom end is equipped with round protractor.It is equipped with round shaft in the middle part of perpendicular ruler, has a vertical ink line from the center of circle in the middle part of shaft, angle is measured in conjunction with the size of perpendicular ruler top bottom end.With straight trough mouth extrusion link shaft and perpendicular ruler lower part, keep perpendicular ruler top and the bottom foldable.Perpendicular ruler lower part is equipped with groove, places the sliding block with rotatable graduated scale in slot, and sliding block ruler with a scale is moved freely along impression orbit, can enclose rotate around the axis drafting and the angled straight line of other straight lines or the straight line with a certain straight line parallel.Totally carry T-square, drawing is more convenient.
Description
Technical field
This product is related to engineering graphics field, in particular to a kind of foldable and multi-functional drawing Novel T-square.
Technical background
In machinery, building, the industries such as gardens can all use and arrive T-square, and traditional T-square is crossfoot, erect ruler and constitute, institute
The larger not Portable belt of volume is accounted for, while parallel lines and the straight line with a certain straight line certain angle can not be drawn.So producing one kind
Multi-functional T-square can solve problem above.
Summary of the invention
The present invention provides a kind of foldable portable, draws parallel lines and the novel fourth with the angled straight line of a certain straight line
Word ruler.
To solve the above problems, implementation is as follows the present invention provides Novel T-square:
This product is fabricated using transparent hard plastic.(it is as identical as this product in still constructed using other materials, then it is considered as
Belong to the scope of the present invention)
The utility model T-square is erected ruler top (2) by crossfoot (1), is erected (3) and perpendicular ruler lower part (4) composition in the middle part of ruler, is erected ruler
Top (2) can edge, crossfoot notch (1-1) track sliding, can be tightened with the fixed knob (1-4) on crossfoot, by gear (1-3) squeeze
Pressing is fixed, thus fixed perpendicular ruler top (2).Perpendicular ruler lower part (4) can be rotated along straight trough mouth extrusion (3-2) thus by perpendicular ruler lower part
(4) it is folded with perpendicular ruler top (2).The angle that the line of ink marker (3-1) of (3) and the formation of perpendicular ruler top (4) lower end can be read in the middle part of perpendicular ruler
Degree draws the straight line with a certain straight line at required angle.Perpendicular ruler lower part (4) are adjusted, its boundary is overlapped with specific line segment, tightens
Knob is fixed, then slides perpendicular ruler top (2), mobile sliding block (4-3), and rotating scale ruler (4-4) measures required distance, along perpendicular ruler
Straight line is drawn in lower part (4) sideline, can draw the parallel lines of required distance.
Detailed description of the invention
Embodiment further illustrates this product in conjunction with attached drawing:
Fig. 1 is the structural schematic diagram (wireframe) of T-square
Fig. 2-1 is crossfoot (1), and Fig. 2-2 is crossfoot gear (1-3) and its notch sectional view
Fig. 3-1 is in the middle part of perpendicular ruler (3), and Fig. 3-2 is shaft disk (2-2), and Fig. 3-3 is that the arc angle in shaft disk is put
Big figure, Fig. 4 is sliding block (4-3) and Fig. 5 is graduated scale (4-4).When Fig. 6 is that the present invention implements to draw parallel lines operation, use
State diagram.When Fig. 7 is that the present invention implements to draw the straight line being at an angle of with a certain straight line, usage state diagram.Fig. 8 is of the invention real
When applying fixed perpendicular ruler top (2) operation, usage state diagram.Fig. 9-1 Fig. 9-2 Fig. 9-3 is that the present invention successively implements to fold T-shaped
When ruler operates, the perspective view of use state
Specific embodiment
] draw parallel lines.Perpendicular ruler lower part (4) is rotated, is overlapped perpendicular ruler lower part (4) boundary with existing straight line, is tightened solid
Determine knob (3-3) to slide perpendicular ruler top (2), the graduated scale (4-4) on rotary slider (4-3) measures specific length, under perpendicular ruler
Straight line is drawn on portion (4) boundary, the drafting of spaced parallel lines needed for completing, such as Fig. 6.
It draws and is at an angle of straight line with a certain straight line.The center of circle of shaft in the middle part of perpendicular ruler is fixed on this straight line, utilize disk
The disk center of circle (2-2) is overlapped, by perpendicular ruler lower part sideline and selected angle by the Angular Dimension on (2-2) with drawn straight line
It spends vertex to be overlapped, (3) rotation in the middle part of perpendicular ruler, the line of ink marker (3-1) of (3) and the required Angular Dimension weight of disk in the middle part of perpendicular ruler
When conjunction, along corresponding boundary mapping straight line, line drawn in this way and former straight line constitute required angle, complete angle and draw, such as Fig. 7.
Fixed perpendicular ruler top (2).Perpendicular ruler top (2) is slided into required position along convex groove (1-1), is tightened on crossfoot
Two fixed knobs (1-4), fixed gear (1-3) is squeezed, thus fixed perpendicular ruler top (2).Such as Fig. 8.
It folds.It, will be under perpendicular ruler when (3) and perpendicular ruler lower part (4) are in having on straight line in the middle part of perpendicular ruler top (2), perpendicular ruler
Portion (4) is whole to rotate around straight trough mouth connector (3-2), and perpendicular ruler top (2) is close to perpendicular ruler lower part (4) surface, completes folding
It is folded, such as Fig. 9-1, successively implement shown in Fig. 9-2, Fig. 9-3.
