Abstract
A multifunctional square ruler aims to solve the problems of the traditional square ruler that the function is monotonous, only horizontal straight lines can be drawn on a drawing board, other tools need to be used when other line shapes are drawn, thereby causing great inconvenience in drawing. The multifunctional square ruler comprises a main ruler, a ruler head and an auxiliary ruler; the main ruler adopts a pane-shaped ruler body with a transparent middle part; two longitudinal edges on the inner side of the pane are in slide fit with longitudinal grooves on the two sides of the auxiliary ruler integrating a protractor template, a conventional engineering symbol set pen template and a curve template into a whole; the auxiliary ruler and the main ruler are locked or unscrewed through a thread positioning knob; and a second auxiliary ruler passes through a positioning hole and a screw hole on the straight angle line of the protractor template, and is rotationally connected or locked to be fixed through the thread positioning knob. The multifunctional square ruler has the characteristics and the benefits as follows: the square ruler integrates various functions as a whole and keeps the original function of a square ruler, through which a user can draw a perpendicular line at a fixed length, a line segment at an arbitrary angle, conventional symbols, conventional line segments and curve and the like by matching the templates on the auxiliary ruler with the second auxiliary ruler; and the utility model has the advantages of multifunction, low cost and easy carrying, provides convenience for drawing and improves the work efficiency.
Description
Technical field:
The utility model relates to a kind of drawing instrument, relates in particular to a kind of multi-functional T-square.Be mainly used in manual drawing the in the engineering design.
Background technology:
As everyone knows, existing T-square function singleness, can only on chart board, draw horizontal straight line, when drawing vertical line or at any angle during straight line, must need prepare various drawing instruments when therefore charting, not only the price height by means of set square or protractor etc., and not portable, bring a lot of inconvenience to drawing.
Be embodied in:
T-square not only uses in drawing such as engineering, also often uses in teaching practice, finds in practice, and many technotes need repeat to draw, and waste time and energy.
T-square " 0 " scale is fixed, and when needing the fixed length draw line segments, it is pretty troublesome also to need to recomputate its relative length, and inefficiency.
When on on-plane surface, mapping,, when drawing parallel lines, can cause between the straight line of drawing out not parallelly, have a strong impact on drawing quality owing to the reasons such as gravity of chi.
When drawing with T-square, when needing the picture great circle or drawing semicircle, all need to finish by compasses, very inconvenient.
Summary of the invention:
The utility model is in order to solve the function singleness that existing T-square exists, can only on chart board, draw horizontal straight line, need drawing other can only be by means of other instrument when linear, price height so not only, and it is not portable, bring problems such as a lot of inconvenience to drawing, a kind of multi-functional T-square is provided, it comprises main scale, chi head and secondary chi, described main scale is the penetrating square frame shape blade in middle part, inboard two longitudinal edges of its square frame and collection protractor template, a technote cover template commonly used and template curve secondary chi both sides longitudinal fluting are slidingly matched, and by the screw thread positioning knob with secondary chi and main scale locking positioning or unscrew slip; The second secondary chi is rotatably connected or locking positioning by the screw thread positioning knob by the screw on locating hole and the described protractor template rectangular wire.
Characteristics of the present utility model and beneficial effect: T-square integrates multiple function, not only kept the original horizontal straight line function of on chart board, drawing of T-square, can also utilize the protractor template on the secondary chi and the second secondary chi fixed length draw vertical line, at any angle line segment, draw great circle or semicircle, utilize a technote cover template commonly used and template curve on the secondary chi to draw conventional sign line segment and curve, and improved drawing quality by auxiliary parts such as on-plane surface level meter and screw thread positioning knobs.Realize the many usefulness of a chi, and cost is low, portable, provide convenience to drawing, improved operating efficiency.

The secondary ulnar surface structural representation of Fig. 2 the utility model
The structural representation of Fig. 3 the utility model second secondary chi
The specific embodiment:
Multi-functional T-square, it comprises main scale 1, chi head 2 and secondary chi 3, described main scale 1 is the penetrating square frame shape blade in middle part, inboard two longitudinal edges of its square frame are slidingly matched with the secondary chi 3 both sides longitudinal flutings that integrate protractor template 3-1, a technote cover template 3-2 commonly used and template curve 3-3, and by screw thread positioning knob 3-4 with secondary chi 3 and main scale 1 locking positioning or unscrew slip; The second secondary chi 4 is rotatably connected or locking positioning by the screw thread positioning knob by the screw 3-5 on locating hole 4-1 and the described protractor template 3-1 rectangular wire.
Be provided with the on-plane surface level meter 1-2 that constitutes by the horizontal observation window of liquid state in the end of described main scale 1, on observation window, be provided with one group of equidistant vertically directrix of different colours.
Be provided with parcel tray 2-1 and pencil-knife 2-3 on described chi head 2, described parcel tray 2-1 is provided with and opens 2-2.
The edge 3-6 that described secondary chi 3 stretches out a side is provided with graduated scale.
Be equipped with graduated scale 4-2 on the both sides of the described second secondary chi 4.
Be provided with slideway 4-4 on the described second secondary chi 4, sliding or lock with a cover annulus 4-3 is connected.
During use, pencil and rubber etc. parcel tray 2-1 be can be put into, keeping and use are convenient to; Template on the secondary chi 3 not only brings convenience to drawing, and accurate positioning, the drawing accuracy height of drawing out.During drawing, can secondary chi 3 be slided on main scale 1 according to drawing needs, draw after being tightened by screw thread positioning knob 3-4 the scale location on main scale 1 or secondary chi 3 more again.Because have graduated scale 3-6 on the secondary chi 3, removable again location has avoided " 0 scale is fixed " need recomputate its trouble with respect to main scale 1 length, has improved operating efficiency.
When on on-plane surface, drawing parallel lines, can utilize the liquid horizontal observation window on main scale 1 end, be in the position of directrix on the observation window, conveniently draw out parallel lines by bubble among the eye-level instrument 1-2.Be on which bar directrix of level meter 1-2 for the ease of memory bubble two ends, the directrix on the observation window has adopted different colors.Solve uneven problem between the straight line of drawing out on the on-plane surface, improved drawing quality.
The second secondary chi 4 can solve and draw great circle, decide radius picture circle and the second secondary chi 4 is used with protractor 3-1 can be in the problem of arbitrarily angled picture fixed length straight line.Paintbrush slides on slideway 4-4 by a cover annulus 4-3, determines radius of circle according to the graduated scale 4-2 on the second secondary chi, 4 both sides of the edge again, is that circle is drawn in the center of circle with screw 3-5.After determining good size, drawing after fixing by the screw thread positioning knob can be better again.
